Before starting any painting work, in order to achieve a high-quality result, it will be necessary to clean the surface from all kinds of contaminants. For such a case, a special mini-sandblast is suitable, which can be used at home. In this article, we will take a closer look at the characteristics of such a compact sandblasting for a small compressor.
Peculiarities
This small machine is designed for abrasive surface preparation. The directional flow of the sand jet allows you to get rid of dirt, change the structure of the coating and engrave all kinds of patterns . In addition, this technology, with its high efficiency, makes it possible to clean various surfaces even in hard-to-reach places. After appropriate treatment, the surface is ready for maximum adhesion to paints and varnishes.
The most relevant field of application of this method is the cleaning of a metal surface during auto repair . Using high jet pressure, old coatings, rust, scale are removed, and at the same time a perfectly cleaned surface is obtained. Parts painted after such processing serve for a rather long time. A similar technology can be applied to work with concrete, wood and brick products.
Small apparatuses differ from industrial design characteristics and used pumping equipment
No such device will do its job better than a sandblasting model. Indeed, after the operation performed, no scratches remain, as in the case of using sandpaper, but at the same time the most inaccessible places are cleaned.
Principle of operation
All sandblasting devices have the same design, which consists of the following parts:
- compressor unit - the main device required to obtain air;
- receiver - designed to accumulate air under pressure;
- gun - necessary for supplying a mixture of air, abrasive;
- a special tank for filling the abrasive;
- a system that allows you to monitor the pressure level of the working mass at the time of supply to the gun;
- general control system;
- connecting hoses for air supply;
- a wire for connecting to a power source.
The principle of operation of this sandblasting unit is as follows:
- the compressor by means of injection creates air pressure;
- there is an air supply and a simultaneous supply of abrasive to the gun;
- an air-abrasive mixture is released under pressure;
- sand particles begin to work, removing dirt from the surface, while sanding it at the same time.
What can be made of?
For periodic work in a domestic environment, it is quite possible to get by with a home-made device, since a self-made model will cost much cheaper than industrial counterparts. There are a number of options for such designs, taking into account what the master has at hand . Next, we will explore several assembly options.
Gas cylinder
For the manufacture of this structure, you will need the following components:
- empty bottle;
- ball valves - 2 pcs;
- a piece of pipe for a funnel intended for filling sand into the chamber;
- tees - 2 pcs;
- hoses with a diameter of 14 and 10 millimeters for supplying the mixture;
- hose clamps.
Manufacturing procedure:
- clean and dry the inside of the cylinder;
- drill holes at the bottom to install the crane and fill the sand;
- install a crane;
- fix the tee and the mixing block behind the tap;
- a second valve is installed on the balloon block, followed by a tee.
For more convenient and easy movement, the wheels should be welded to the structure.
High pressure washer
Without a bottle at hand, such a device can be made from any high pressure washer. This will require:
- armored hose;
- ceramic nozzle;
- tee with nozzle;
- abrasive capture tube;
- feed adjusting block.
This type of construction works electronically. The incoming liquid moves through the mixing block and at the same time creates a vacuum in the abrasive feed channel. Under high pressure, together with the liquid, it is directed to the surface, which is cleaned.
Air blow gun
This is the most compact sandblasting model. To manufacture this option, you will need:
- blow gun;
- tee;
- ball valve;
- clamping nut.
In this case, an ordinary plastic bottle is suitable as a container for sand.
Spray gun
To collect this model, you will need the following parts:
- a gun with the principle of operation of the mixing valve;
- handle with a special device for air intake;
- plastic container for sand;
- tee;
- ball valve.
Assembly principle:
- bore the gun, bringing the outlet to the required diameter;
- fix the mixing tee to the gun;
- attach and secure the supply and circulation hoses;
- the volume of a plastic bottle is enough to clean the surface in a 30-minute period.
Fire extinguisher model
This design corresponds to the above described view from a balloon. A plug must be installed here to seal the top. You should also make two holes: at the bottom and at the top. A leg is welded to the bottom, made mainly of reinforcement. After installing the fittings, the unit is completely ready for operation.
How to use the device?
This device cannot be considered safe, and in the case of self-assembly, you should even more think about precautions. To avoid the risk of injury, the following nuances must be taken into account:
- before starting work on cleaning the surface, it is imperative to check all connections for strength and tightness, such actions must be carried out every time;
- use equipment (glasses, gloves, respirator), which is mandatory for any master in such work;
- free up the nearby space, driving away both people and all living creatures;
- before starting the unit, open the valve supplying the abrasive;
- before connecting to the network, the device must be grounded;
- closely monitor the quality and dryness of the sand;
- avoid tension on hoses;
- regularly monitor the condition of the nozzle;
- after each operation, carry out preventive lubrication of valves and filters.
In addition to observing safety measures, these measures will help to extend the life of the device.
For the best performance on all surfaces, a right angle is recommended
Now, having an idea of the device and the principle of operation of a mini-sandblaster, anyone who wishes, finding a set of components at hand, can make a useful structure.
