Do-it-yourself foaming agent for contactless. Do-it-yourself car shampoo without harmful substances. What to make a foam generator from

Every car owner must visit the car wash. Water treatments help keep the vehicle clean and special meansapplied during washing create an additional barrier to dirt and protect the body paintwork. For high-quality cleaning, a thick active foam is used, obtained by foaming in a special device. Some car enthusiasts use self-made foam generators when washing.

Benefits of using a foam generator for car wash

The foam generator is sold in a shop that sells equipment for professional car wash. The price of the purchased foam generator is from 10 thousand. And if you take a branded device, you will have to pay twice as much. Not everyone can afford such costs. Therefore, below is a small instruction on how to make a foam generator yourself and spend only 500 to 2 thousand rubles on its manufacture. In addition to saving money, the owner of a homemade generator receives the following benefits:

• saving time - washing the car with active foam is faster, by about 10-15 minutes;
• detergent is consumed more efficiently and more economically;
• active foam eliminates the use of a sponge, which helps protect the paintwork from mechanical stress;
• the foam generator allows you to thoroughly wash hard-to-reach places.

Do-it-yourself assembly: schematic drawing and manufacturing instructions

To understand the principle of operation of the foam generator, a diagram is placed below. Water is poured into the container and the detergent concentrate is added. Air from the compressor is supplied through a shut-off valve. To control the pressure in the container, a pressure gauge must be used. The outlet produces a mixture of water and detergent. It passes through a foamy tablet which produces a dense active foam.

A simple and clear diagram of the foam generator helps to understand the principle of the device

What you need to build

For self-made generator will need:

1. Capacity.
2. Pressure gauge.
3. 1 shut-off valve (it only allows air to pass in one direction).
4. 1 tap (they regulate the supply of finished foam).
5. Metal tube.
6. Reinforced hoses that can withstand a pressure of 6-8 atmospheres.
7. Metal clamps for secure connection of hoses and fittings.
8. Foam tablet.

First of all, you need to decide on the capacity. The main requirement is the ability to withstand a pressure of 5-6 atmospheres. If it is possible to carry out welding work, then a receiver from a truck or an old compressor can be used for the generator. Weld 2 1/2 inch fittings and a filler neck onto the body from above. The optimal volume is 20–30 liters, which is enough for personal use.

If an old water heater is lying around in a garage or shed, then it can be used to create a foam generator. In this case, no welding work is necessary.

Homemade unit from an old sprayer

In the household of every summer resident, there is always an old sprayer, which is a pity to throw away. With a small upgrade and using the drawing attached above, it can be easily converted into a foam generator. Let's get started:

Remember that the sprayer body can withstand 4-5 atmospheres pressure. Do not overdo it, control the pressure on the pressure gauge.

We buy a foam tablet in a store or make it ourselves. The main element of the tablet is a metal mesh. It is easy to make from a regular metal dish brush. It is sold at any hardware store.

Using a DIY device: highlights

Pour water through the neck by ⅔ of the total volume of the container and add the detergent concentrate in the amount indicated on the package. Usually it is 10-20 g per 1 liter of water. We securely close the neck and the outlet valve. We supply from the compressor to the input compressed air... Be sure to monitor the pressure on the arrow of the manometer.

At the outlet, we connect a hose with an irrigation nozzle. We open the tap gradually. We direct the hose to the car and apply the foam. The density can be adjusted with a garden irrigation nozzle.

The dense active foam quickly corrodes dirt and removes it from the surface without a sponge

The foamed car should stand for 10-15 minutes. Active foam flows down with the dirt. Then it is enough to wash off the foam with plain water and wipe the surface of the car.

As you can see, it is not difficult to assemble a foam generator with your own hands. No special skills or abilities are required. It will cost 10-15 times cheaper than purchased. The quality of the sink will increase several times, and the savings in time and detergent are noticeable. Remember that the eyes are afraid, but the hands are doing. Good luck!

The cost of the simplest car wash is 300-400 rubles, which is quite a lot and ineffective, given that for the cost of 5 such car washes, you can assemble your own penegenerator with your own hands to wash a car.

Car wash today is a luxury, even the simplest one, not to mention contactless with the help of a foam generator.

The cost of the simplest car wash is 300-400 rubles, which is quite a lot and ineffective, given that for the cost of 5 such car washes, you can assemble your own penegenerator with your own hands to wash a car. Of course, you can buy a new and branded one for 16-18,000 rubles, but again this is not effective and expensive. When assembling this equipment, the most expensive part will be the compressor, which is responsible for air injection, but you can buy an automobile compressor, which will cost 1200-1600 rubles.

Foam generator device and principle of its operation

Before you start building your own foam generator, you need to understand exactly how it works. The main purpose of this device is the release of foam and its further smooth and uniform distribution over the body of the machine.

The water jet passes through the solution, which is mixed with the air discharged from the compressor. During this process, an active foam is formed, which can easily clean a car from dirt. In addition to the fact that the foam has formed, it must be dense, which is achieved by passing slightly foamed soapy water through a tablet (multilayer metal mesh), which intensively foams the solution. The liquid then flows onto parallel regulating plates to keep the solution flow flat. The hose is necessary to remove the foam; a nozzle for distributing water flows or just a shower nozzle is attached to it.

The most simple way make a foam generator for car washing from a garden sprayer of the Beetle type. In structure, a garden sprayer is almost identical to a foam generator. In total, it is necessary to spend 1-1.5 hours of time to change the sprayer to the foam generator, if, of course, all the necessary parts for creation are there.

So, to create a foam generator from a garden sprayer you will need:

• Sprayer capacity;
• Air flow pressure gauge;
• One-way valve allowing air to pass in only one direction;
• Flow regulator or just a tap;
• Air injection pipe;
• A hose with a wall thickness capable of withstanding a pressure of 6-8 atm;
• Metal bandage for joints;
• Foam mesh.

The first thing that is needed for a foam generator is a container that can not burst at a pressure of 5 atmospheres; the sprayer capacity is just suitable for these purposes, since the walls can withstand a pressure of 4-6 atmospheres.

Step by step, the process of creating a foam generator from a sprayer for a garden looks like this:

Two metal squeegees: a hose is screwed into the first, air will be supplied to the second

• The final stage is the connection of a car compressor (cost from 1200 rubles) or a compressor purchased in the secondary market specifically to create a foam generator.

This method is even easier and simpler than the previous one. To make a foam generator you need:

• Automotive compressor (cost from 1200 rubles);
• Pistol;
• Canister (as a container);
• Nozzle;
• Hoses;
• Manometer;
• Fitting.

All together it will cost a maximum of 1600-1800 rubles at a cost of one car wash of 300-400 rubles.

The first thing to do is to take a tube with a length of 60-65 cm (in general, the length of the tube can be different and depends on the size of the plastic canister, the length of the tube should be 2-3 cm less than the height of the canister from the hole to the bottom) and fill with fishing line, which will act as a foaming tablet. The ends are covered with plugs with threaded holes. A T-shaped transition link is mounted on one of the holes, a fitting is mounted on the remaining hole. Two hoses are connected to the T-shaped adapter, one of the holes must have a tap to control the flow of water, the second is needed to connect a pressure gauge. It should be remembered that the canister must be made of dense plastic that will withstand a pressure of 5-6 atmospheres, otherwise all the work will go down the drain.

Many are trying to find a compressor on the secondary market, however, for the purpose of washing a car, a cheap car compressor with a pressure gauge is quite enough, the price of which is 1200-1300 rubles, and the pressure created by even the cheapest model ranges from 2 to 7 atmospheres, which is what is needed to create foam generator.

How to make a foam generator with your own hands or where to start?

How to make a foam generator with your own hands? The answer is simple - you have to try. For the manufacture of a foam generator, it is important to choose not a compressor, but a container that can withstand a huge volume of water and pressure inside. All the variations of creating a foam generator presented above are the simplest and most understandable, but also one of the most dangerous when using because of the case. So, with the slightest deviation in pressure, the device can crack and leak at best, or explode in your hands at worst. The best base (capacity) for this kind of foam generator would be gas bottle, but to create a foam generator in this case, you will need experience in using welding and, in fact, welding machine, which is long and problematic, but reliable.

How to use a homemade foam generator?

The step-by-step process of using the generator looks like this:

• Through the main hole - the neck, water is poured, preferably purified, to 60% of the volume;
• In the water, again through the neck, the detergent concentrate is poured in a ratio of 10-18 grams per 1 liter of water;
• After the first two stages, the tap and the neck are closed;
• The compressor starts up;
• Air is supplied to the container;
• A hose with a gun is connected;
• Open the tap very slowly;
• Foam is applied (its density can be easily adjusted with an irrigation nozzle or a gun, depending on what is installed in the form of a distributor);
• The foam should be on the surface of the car for 15-20 minutes;
• After the foam has been supplied, you can rinse the container and pour water into it and, in the same way as the foam was applied, rinse it off, but with clean water.

Contactless car wash for many car owners it is a luxury, as they spend up to 300 rubles. at the next washing of the car, not everyone will allow himself. Buy a mini-sink, spending up to 15 thousand rubles. also not many are solved.

But to afford a foam generator for washing with your own hands from a sprayer, spending minimal funds, it is quite possible by making it yourself from old sprayers and a few simple parts. Such a foaming agent will provide a constant, almost free, but fast and effective car wash at home.

Principle of operation

The main purpose of the foam generator is foam formation from shampoo and water, which after generation is evenly distributed over the surface.

The sprayer as a foam generator is based on mixing two foam-forming components under the pressure of compressed air and supplying foam to the surface.

In practice, this is realized by mixing water and detergent in a container, compressed air pushes the solution through the foam tablet with the formation of a dense active foam.

For more information about the operation of the foam generator from the sprayer, see the video:

Necessary materials

For the efficient operation of the future foam generator, the purchase of expensive components, as well as the use of new parts and devices is not necessary. When making a device with your own hands, you will need the following parts and materials:

• container from a garden sprayer. For this, containers from sprayers, garden, as well as the "Quasar" or "" models are suitable.

• For these models, the pump or pump is dismantled;
• pressure gauge with a scale up to 10 atm;
• one direction air check valve nipple. Two 0.5-inch squeegees with four nuts and gaskets;
• a tap that regulates the supply of foam;
• metal tube and;
• reinforced hose that can withstand pressure up to 8 atmospheres;
• hose adapter;
• clamps for connecting fittings with hoses;
• foam tablet.

When selecting materials, the first step is determined with a container that can withstand pressure up to 6 atmospheres. Undamaged tank garden sprayer is quite suitable for these requirements. You can buy a foam tablet at a store or make it yourself.

The basis of the functioning of the foam generator from the Beetle sprayer is a metal mesh, which is easy to make from a metal brush designed for washing dishes, or a tightly knit lump of fishing line.

Safety engineering

When making a foam generator, it must be borne in mind that the container in the sprayer can withstand pressure up to 4-5 atm... When injecting air into it, be sure to follow the pressure gauge reading or control the pressure with a relief valve.

The device must not be used for other purposes by pouring toxic or flammable substances into the container.

How to make a foam generator from a sprayer with your own hands? If you used to make your own for a snow blower, did it, assembled it yourself or for a walk-behind tractor, then it will not be difficult for you to make a foam generator yourself from a sprayer.

If the necessary parts and parts are available, the foam generator is assembled in the following order:

• in the container from the sprayer the hand pump is removed and holes are jammed;
• a pair of squeegees, 1.27 cm (0.5 in) in diameter, are installed at the top of the tank The parts are fastened with nuts on both sides, and their tightness is achieved using gaskets;
• a T-shaped adapter is placed on the squeegee for air supply, a pressure gauge and a shut-off valve are placed on it, and a tube is attached inside, slightly less than the height of the tank. This is necessary in order for the air to enter from below. Thanks to this, the liquid foams;
• the second squeegee is for the foam outlet. A tap, a foam tablet is installed on it, and for quick connection of the hose - easy removal. A metal tube is connected to the hose, and to it a nozzle or spray. The foam maker is ready.

For automatic regulation of the pressure in the tank, installation of fittings for air injection control in the form of a valve that releases excess atmospheres.

This frees the operator from constantly monitoring the pressure gauge when air is injected, and guarantees the safety of the device, excluding the possibility of a tank explosion under the influence of pressure.

Multifunctional high quality motor vehicles. He will help you in places where the snow is above the roof.

Motoblocks are the necessary equipment from summer residents and farmers. get acquainted with the advantages of the Niva walk-behind tractor.

A home snow blower is a relatively low power device for domestic use. - This is what you need.

After checking the reliability of all connections and the tightness of the tank, water is poured into it through the neck in an amount of 2/3 of the total volume and concentrated shampoo is added according to the instructions (as a rule, this is up to 2 g / l of water). The neck is tightened securely and the outlet valve is closed.

By pump or compressor through a shut-off valve pump air to the required pressure. The hose with the nozzle is directed to the surface to apply the foam and the tap is slowly opened. Density of application can be adjusted with a nozzle or a nozzle.

Conclusion

Self-assembly of the foam generator is quite simple, and does not require special knowledge and skills for this. The cost of making it will be 10-15 times lower than the factory device. To do this, you need to draw up a product diagram and a sequential action plan, as well as correctly select all the necessary materials.

When assembling the device, safety requirements must be taken into account: since the foam generator tank operates under pressure, its permissible value is controlled by a pressure gauge, and all parts and connections must be operable and reliably assembled.

Hello to all homemade lovers!

In today's article, I want to show one of the options for making a simple foam generator from a conventional garden spray.

This sprayer will only take a few minutes to complete and the result will be great! Verified personally!

A couple of years ago, I published my article on manufacturing, I want to say that this homemade product works to this day and helps out very well when washing engines on a car, but in order to clean everything better, you need chemistry, and that's what this homemade product was for. foam generator.

Materials for making

• garden sprayer with a metal spout (sold in any household store);
• dishwashing sponge (hard top);
• needle or awl.

Making a foam generator

You don't need to do anything else inside. The only thing, if you don't want to pump air manually, you can install a nipple from tubeless tires and pump air with a compressor, but I did not do this, since a regular pump is enough.
Next, remove the metal spout from the spray, take the upper part of the sponge, cut off a piece that is suitable in size and insert it tightly into the spout, as shown in the photo below.

And that's actually the whole revision! As I said, everything is done in just a few minutes.

But actually

Car shampoo for contactless washing can be made by hand. The financial situation of the population determines the number of car washes in cities. From time to time, some car owners find this service expensive, they choose car shampoo to tidy up the car manually. Any car owner often uses automotive cosmetics, among which car shampoo has become one of the most popular products.

The use of high-quality composition makes it possible to give the car the new kind, it is easy to clean the body, optics, bumpers and glass from dust and dirt, which spoil the look of the car and affect driving safety.

Features of car shampoos

The use of chemicals that are not suitable for washing conditions or of poor quality often leads to negative effects, which are:

• The presence of streaks and stripes on the paintwork surface.
• Poorly washed dirt and stains.
• Blurring of body paintwork and glazing.

Also, incorrectly chosen cosmetics for the car can lead to the most serious consequences - defects in the body paint and varnish surface. Many car owners, knowing that an ineffective product will be offered to them in a car store for a large amount, often use different recipes for making car shampoo on their own. But, before starting to consider the recipes of cleaning chemistry and methods for their manufacture, you need to better understand all the subtleties of car washing using the latest technological methods and the latest automotive cosmetics.

Vehicle washing technology

Currently, the owners of private cars have two ways to bring their car to a normal state after driving on domestic off-road or driving in rainy weather:

• Using the available detergents at hand chemical substances wash the car yourself.
• Contact a commercial car wash.

The first method is often used with a simple soapy water... Many car owners believe that in the composition of factory industrial chemicals there is a simple soap, with the addition of fragrances that impart a scent to cosmetics, and increasing its value to the level of well-known companies.

To wash your car, the use of proprietary formulations is required. Their composition, viscosity and properties are well combined and make it possible to:

Do the least damage to the paint and varnish surface and exposed metal and plastic parts.

Features of factory auto cosmetics

The features of these shampoos include:

• Availability of shampoos different recipes and consistency.
• A large assortment of packaging, from aerosols to canisters of significant volume.
• The ability to remove serious dirt, bitumen tar, oil stains, dirt that simple cleaning products cannot cope with.
• Abundant foaming.

By the first sign, car shampoos can be subdivided:

• Liquid solutions commonly called car shampoos.
• In the form of a paste that is applied directly to the surface or dissolved in water.
• Powder, dissolving in a lot water.

Liquid formulations are divided:

• For non-contact washing, used for washing the machine with a jet of water under high pressure through a special nozzle.
• For contact washing, used for washing vehicles by hand with a cloth or sponge.

At present, nozzles are produced that serve for contactless car washing; the device, shape and number of nozzles that contribute to large foaming may be different.

Homemade car shampoo

Usually, the car owner is faced with a problem when you need to give the car a normal look, but there is no good car shampoo. In such a situation, you can make a tool from scrap materials. The recipe for a self-made cleanser is quite simple, and its constituent parts include active chemicals:

• Anti-corrosion additives.
• Foaming agents that increase the quality and speed of washing and erasing dirt.
• Complexing agents that reduce water hardness and improve the fluidity of the cleaning solution.
• Synthetic components - ethylene, propylene, petroleum substances.
• Natural ingredients - fish oil, non-edible oil, wax.

To make a car shampoo that matches the factory recipe, a little polish and fragrances are usually added to it. The main effect on the quality of homemade shampoo is the surfactants, which make up the bulk of the composition, as well as the pH value equal to pH \u003d 7.

In special cases, low alkaline surface active elements can be used. It is these elements that have a major effect on the efficiency and quality of dirt removal. Their content in the prepared composition is in the range of 5 - 30%. For a car shampoo made in a domestic environment, you can select different types fatty alcohols offered for sale in household chemistry departments.

The recipe for individual elements is determined independently, by the method of errors and trial. After mixing the considered ingredients, a car shampoo is formed, which is used when different types vehicle washing. If washed by hand with a sponge, then the solution is applied to the contaminated areas with a sponge, and when washing with a contactless method, it is poured into a special container.

Safety precautions when preparing car shampoo

Any solution for processing a car is made by dissolving a prepared concentrated car shampoo with a given amount of water. When using homemade shampoo, so that there are no unpleasant consequences, you need to follow some rules:

• If a washing solution remains on the body, rainbow spots and stains may form.
• After washing the paintwork, headlights and glass, wipe dry with a special soft cloth or napkin.
• During contact washing, the applied solution in concentrated form should be quickly ground to foam.
• A very high concentration of shampoo often leads to defects in the coating of the car body.

Currently, the automotive cosmetics trade network has a large selection of different shampoos for hand washing in various containers. Hand shampoos allow you to wash your car with a regular sponge. To make this procedure simpler, special nozzles are often used to dissolve shampoo. The advantage of manual car shampoo is the neutral balance of alkali and acid.

Car washing becomes safe due to the peculiarities of the composition, which allows you to quickly wash the glass and the body of the vehicle. When the machine dries, a special film forms on the surface to protect it from dirt. Many products make the surface shine.

At the special trading platforms, you can now buy easy-to-use cylinders that spray a special composition on the glass and body. They are well suited for traveling by car.

To make your own shampoo for a car, it is better to use non-aggressive substances in order to prevent the possibility of a negative effect on the body coating. Car washing is considered a responsible procedure that requires knowledge. Therefore, drivers should know which shampoo for hand washing is better to purchase. Everyone wants their car to be clean and free from harsh chemicals.

What leads to improper use of chemistry

It must be said that a large number of car owners use not very high quality chemical agents, because they do not know how to properly wash the car, if there is no special shampoo available. As a result, after using low-quality chemicals, dirt, stains and stripes are revealed. In addition, the misuse of such products often causes cloudy spots on the paintwork, which is not a positive factor.

In order to prevent such negative effects of the use of various chemical detergents, it is advisable to use only the most reliable and high-quality special shampoos for automotive technology.

The use of high-quality chemicals will significantly save time and effort. Now all drivers can know how to choose the right car shampoo to wash in a non-contact way. The use of such tools is advised only at specialized car washes.

A specially conducted test of automotive chemicals for a non-contact method shows them high efficiency, however, when choosing, experts advise determining the presence of a permit or a special certificate of compliance, which should always be included with the shampoo.

When car owners do not follow the instructions, the surface of the body is damaged. Over time, negative factors can only increase. This sink is well suited for cars with a new coating. Today we can say that only a special shampoo for the non-contact method of body treatment is the best for external cleaning of the car. Drivers take their time to use non-contact shampoo on new cars all the time to prevent damage to the bodywork. Possible defects in the paintwork will cost them too much.
