NEEDS FOR SANDBLASTING
Sandblasting machines are composed of four main parts: air filter, compressor, compressed air dryer and sandblaster.
The compressors are used for the production of compressed air, the air filter is used to obtain air and pressure at the pressure and flow until the end of the blasting process. Because the use of large amounts of air in the blasting works is required, your compressor request was important. Compressors are divided into old screw and piston. Screw compressors are preferred in high pressure apparatus blasting process. Before the compressed air produced by the compressor goes to the blasting drum; pressure tested and certified pressure is deposited in the tank.
Another important part is the compressed air dryer. Since the high moisture content of the exposed moisture is condensed by the condensation of the consumable material, the sand processing begins to be intermittent, and this process also allows abrasive twine material contacting with high humidity to be made at an early age, so that the preparation of such conditions of the blasting process the importance of the compressed air dryer once again emerges.
One of the main parts, the blasting drum is a pressurized container. Loading of consumables on the application surface of this boiler, the risk of possible explosion Produced in the compressor and compressed air in the air tank into this boiler is filled into. Compressed air that is filled up moves the plug that closes the sand loading hole upwards. With the closure of the plug, the compressed air searches for the outflow path and moves to the outlet valve at the bottom of the boiler. It uses the appropriate abrasive consumables and air mixture, which is the duty of the valve in the room. In order to determine the desired effect in the blasting process, abrasive consumables mixed with 3-4 m3 air at 6-8 bar pressure will be sprayed. During the process, it is often necessary to stop and not waste time by filling the boiler with sand, and prefer the blasting boilers to be large in volume.
One of the deepest parts of the sandblasting is the blasting nozzle, nozzle located at the end point of the blasting hose. As a result of excessive friction, the nozzle made of wear-resistant material is preferred. Inside the nozzle, adjust the flow of air passing through the blasting feature and there are 6-8 mm internal. The nozzle made of non-durable materials has been used and if the blasting options are the nozzle-wide expansion, the desired fluctuations are made on the product surface. The quality of the nozzle was important in order not to give rise to the surfaces of the wavy products.
Abrasive used for blasting. Effective cleaning, cleaning, angular cleaning. In this way, keep in mind that the material is better attached to the surface than when it is being applied. Before the particles are angular, the cutting feature can be confirmed by the blasting process. It can be applied in the same area for a long time and may change the thickness of the surface in the sandblasting. Likewise, the size of the abrasive consumables is very expensive, which is possible in the machining process to be applied at the end of the sandblasting application. In order to avoid over-consumption of these materials, it is useful to re-emphasize the need to be very sensitive.
The sandblasting product will not be processed and managed to process. Globalized, united burrs, traces, stains, etc., produced on the surface of the material in question. It is used by removing unwanted results. For these situations, if angular materials were used, some of the deep cuts on the surface of the product would come to the future mata and work hard on the soils that were placed on these sections. Global abrasives most often need to be removed before the final sale.
In dry weather, blasting should be done and finished as soon as possible. Because, after cleaning the rust and unwanted formations on the steel, the corrosion is even more vulnerable. If the air is damp, the sandblasted steel starts to blacken and rust immediately.
Before the painting for surface preparation according to the paint sheets, paint preparation will be started based on the authorized inspector report brought by the Contractor.
Shot blasting surfaces will be protected from external weather conditions and at least 15-20 microns of shop primer should be thrown in at least 6 hours or primer paint thickness will be discarded.
