All about sandblasting nozzles on Karcher

In the domestic sphere, there are situations when you have to process various materials using available tools. This also applies to cleaning surfaces, which must be performed before other work processes. A smart solution might be to use a homemade sandblasting, created on the basis of a Karcher water sink.

The sandblasting nozzle on Karcher is quite famous in a certain circle of consumers and has been popular for a long time. Among the main features is the ease of use, which is available due to the simple design. The pneumatic equipment, which does most of the work, allows the abrasive to be directed at high pressure. This makes it possible to quickly and efficiently clean various surfaces.

The high degree of convenience is also expressed in the pistol, which is similar to those used in the car wash. It is this part of the sandblasting that is responsible for mixing air currents and water. They, in turn, by means of pressure with an abrasive material, create a mixture, which then comes out.

This applies to both the ceramic nozzle and the hose, which is subject to heavy loads. If we compare such hoses with the usual ones used in sinks, then sandblasting nozzles require more wear resistance. Of course, the abrasive is not water, which only makes the inside of the tube wet. The sand literally cuts the hose, which is why the latter needs a particularly dense structure. For this, it is recommended to use a material with a reinforced inner coating that is more resistant to physical damage.

Another feature of the sandblasting nozzles on Karcher is their simplicity. The device should be as light as possible and have small dimensions, therefore, there are no additional structures such as electronic dispensers and automatic regulators. You will be able to smoothly change the amount of sand taken by yourself, so the workflow can be customized for yourself.

There is a requirement for the abrasive itself, since it must be of fairly high quality and of the correct dimensions. If coarse material with an excessively sharp structure is fed into the hose, then the equipment will wear much faster. As a rule, river or quarry sand of medium or high quality is used in dry form. If it turns out to be wet, then the Preus high-pressure apparatus built into the Karcher will not be able to supply enough abrasive, because the wet material is much heavier than usual.

Having dealt with the features of the work and the structure of the sandblasting, you need to know what it can be useful for. First of all, the most common area of ​​application is cleaning. If a thing has been in the dirt for a long time, which then dried out, then the abrasive material under high pressure will easily wash the object. This approach significantly saves time and effort.

The power and efficiency of sandblasting is also appreciated when working with metals. Sand can remove perennial rust from parts and workpieces.

Sandblasting can clean various types of metals, which is important to consider when adjusting the flow of material. For example, soft raw materials such as aluminum or copper are more convenient to process under different pressures in order to achieve the desired result at a minimum cost.

Sandblasting is also known to be a good cleaner for removing old coatings - paint, adhesives, mixtures and liquids. The use of a solvent sometimes does not pay off due to long waiting times or excessive surface treatment of the required surface. The advantage of the nozzle is the ability to move relative to the desired object, therefore, sandblasting is also used when cleaning various component parts before processing them.

Homemade sandblasting from Karcher consists of several parts.

• Hose. It will allow an abrasive substance to enter the nozzle. It is better not to skimp on this component, opting for reinforced analogs. As for the length, it should be at least 2 meters, preferably three. Such a long distance is necessary so that the worker can use the tool at the optimum range. If the hose is too short, it will reduce the mobility of the sandblasting.

• Nozzle. A very important part of the device, since it is this component that contains the key details.

• Nozzle. We can say that the wear resistance of sandblasting depends on the quality of this thing. Mostly ceramic or metal nozzles are used. The first option is remarkable in that it is more resistant to corrosion, but has less physical strength. Metal is much more reliable, but it has one significant drawback - water easily oxidizes this material, after which rust forms. In any case, the choice of the nozzle should be taken with full responsibility.

• Trigger hook. This part is responsible for the direct supply of the abrasive to the nozzle.

• Dispenser. The simplest dispenser can be a water tap. Thus, you can independently set the output of the abrasive and save it.

• Clamp and fitting. It is these components that are used when assembling the nozzle.

• Abrasive nozzle. This part is lowered into a container with abrasive. By means of pressure, sand will flow through the nozzle, which will subsequently mix with water from the Karcher washer.

Having everything you need, you can start the manufacturing process. It's worth starting with assembling the nozzle. To do this, fix the tip to the nozzle using a thread. Then attach the dispenser, and then combine the main device, the resulting nozzle and the hose using the union and clamp. As a result, you should have a structure that needs to be mounted in the main sink device.

The next step is to use an abrasive attachment. By lowering it in the sand, calculate the approximate consumption of the material. On average, you will need 40-60 kg per cubic meter. meter depending on the force of pressure. In fact, the main part of the assembly consists precisely in the nozzle, and everything else is needed in order to connect the sink, the abrasive and the sandblast itself. Do not forget that with the help of certain actions, sand with water can be used a second time.

For this carry out the cleaning procedure over any mesh container, into which already spent abrasive will fall.

Sandblasting is a tool that works under high pressure, so it is very important to observe safety precautions when using it. First of all, it is necessary to have protective clothing, which in case of contact with abrasive water can prevent the main danger to humans. It should not be forgotten that the respiratory system must be protected while spraying the material and cleaning paint, glue and other substances. Therefore, it is worth using not just protective clothing, but also a breathing respirator, and the best solution would be to equip a suit.

With long-term use of sandblasting, harmful substances can be inhaled, in this regard, take care of the ventilation of the room. It is best to work in open areas where you can find a separate place to use sandblasting. There should be no explosive substances or electronic equipment nearby. If sand gets into it, it can lead to malfunctions.

Consider the selection of shoes with the utmost importance. It must be strong and comfortable, since the legs are the most vulnerable place when using sandblasting. Before the first use, you should familiarize yourself with the principle of operation of washing equipment, so if you have documentation and instructions from Karcher products, then it is advisable to read it. After each working session, it is required to blow the treated surfaces with compressed air and dry with a hairdryer.
