You can consult a professional sandblasting dealer or practitioner to learn more about it and make a wise choice.

1.Depending on the size of the workpiece, choose a box-type sandblasting machine, a mobile sandblasting machine, and an automatic sandblasting machine;

2.It depends on the shape of the product, choose the specifications of the sandblasting machine, generally there are fixed specifications below one meter, and especially large ones should be customized or open.

3.The degree of requirements for the surface of the product, this depends on whether it is dry spray or wet spray, if it is dry spray, there are many choices of abrasives, wet spray is generally glass sand, etc.

4.Some accessories of the sandblasting machine should be familiar, sandblasting guns and sandblasting gloves are things that often need to be changed, because sandblasting is actually very worn.

Sandblasting grade: The sandblasting effect of different sandblasting machines is different, so in order to ensure that the sandblasting effect reaches a certain height, there is a certain sandblasting grade in the sandblasting machine industry.

The most thoroughly cleaned surface is a consistent off-white color with a certain roughness to improve the adhesion of the coating. Grease, dirt, scale, rust, corrosion, oxide and other impurities on the surface should be thoroughly removed.

All grease, dirt, scale, rust, corrosion, old paint and other impurities are removed from the surface of the cleaning grade very thoroughly, allowing for shadows or color differences due to incomplete cleaning, but at least 95% of the surface is SA3 and 5% of the surface is only mild.

Grease, dirt, rust and other impurities are removed from the surface of the more thorough cleaning grade, and rust, oxide scale and old paint are removed, allowing for shadows or color differences due to incomplete removal of rust and oxide scale. If the surface of the steel has been pitted, there will be a small amount of rust or old paint deep in the erosion point.

The non-thoroughly cleaned surface is thoroughly cleaned with grease, dirt, loose rust scale, loose oxide scale, loose patent leather removed, and the oxide scale, rust, paint and coating firmly bonded to the substrate allow a large number of evenly distributed metal spots to appear on the surface after the paint is cleaned.

Working principle of liquid sandblasting machine:

The liquid sandblasting machine uses the abrasive liquid as the feeding power of the abrasive liquid, and transports the evenly stirred abrasive liquid (a mixture of abrasive and water) into the spray gun through the abrasive pump.

Compressed air is used as the acceleration power of the grinding liquid, through the air pipe, into the spray gun, in the spray gun, the compressed air accelerates the grinding liquid entering the spray gun, and is shot out through the nozzle, sprayed to the processed surface to achieve the expected processing purpose. In a liquid sandblasting machine, the abrasive pump is the power for the supply and the compressed air is the acceleration power.
