Different Types of Sandblasting and How They Work

All sandblasters basically work the same. Silica sand with fine texture and grit is utilized to clean and rub a surface, normally metal, of any rust, paint or other undesirable surface materials. This works by using an air-controlled gun with high pressure that fires out the sand at high speed to take effect on the target surface. All sandblasting types use these guns. The interior coat of these guns are made up of a strong material to keep the sand from wearing it away after some time. The only difference is the precise way of how the sand is brought into the gun. Fundamentally, there are three kinds of sandblaster.  

Gravity-dependent  

There are three essential parts to this model. They are the air blower or pressurized air tank, the gun with air hose and a receptacle located over the gun. The hose interfaces with the air tank, and the receptacle is loaded up with sand. At the point when the trigger of the weapon is held down, two things occur. First off, compacted air is discharged through the gun. Secondly, an opening at the highest point of the gun where the receptacle is attached opens. The air pressure moving through the gun and the power of gravity are what makes the sand exit continuously under high pressure.  

Pressure Blasters 

These are all the more frequently utilized by business associations. They are fundamentally simpler to use compared to other but are more costly to utilize. They comprise of a huge container holding sand under high pressure. The idea is comparable to a pressurized aerosol product. A sandblasting gun, mostly needing 2 hands to use, is associated with the port at the highest point of the canister by methods for a particular hose that can endure the sand’s abrasive rubbing. When the trigger is pulled, both the air and sand are forced out as a solitary element. There are a few downsides though. Since the canisters are completely encased, the sand that they fire out can’t be gathered and reused. Once the canister is used, it needs to be replaced. This will be costly.  

Siphon Blaster 

This type is effective in cleaning and stripping extensive surfaces without being expensive. It comprises of three sections. The difference of this type is that it has two separate hoses, one connected to the base of the handle and the other beneath the barrel. One of the gun’s air hose is attached to the compressor. The other one is attached to under the different sand canister. At the point when the gun’s trigger is toggled, the air will create a suction action, which pulls the sand from the repository up the hose and into the firearm to be discharged out the cask. This technique allows the sand that exited the cask and to be collected back, placed again in the canister, and reused over and over. This makes this type cost-efficient.
