What Is Wet Sandblasting Technology?

 Wet blasting is a technique for surface preparation using water, abrasives and compressed air.

"Wet blasting" refers to a technology that uses the power of compressed air to spray a mixture of water and abrasives at high speed to achieve surface cleaning, processing and modification of metals, plastics, ceramics and other materials. Since it is wet processing, it is also suitable for fine processing using abrasives as small as several microns.

Advantages of wet blasting 

Wide selection of abrasive grain sizes, shapes, and materials
Because the abrasive particles are carried by water to the target, finer particles can be used compared to dry blasting.

High fluid control and controllability
The grinding fluid mixed with water and abrasive grains can realize fluid control, so the processing precision is higher.

Less abrasive residue
After machining, the abrasive particles are washed away by water, so fewer particles remain on the machined surface.

Capable of handling ultra-thin targets
The processing pressure is small, and the ultra-thin target will not be damaged during processing.

Adding chemicals can get the effect of secondary treatment
Chemicals can be dissolved in water, and chemical treatment can be performed at the same time as sandblasting.

The principle of wet sandblasting

Wet sandblasting is an easy-to-automate and environmentally friendly way to circulate the grinding fluid. Check here to know wet blasting machine.

The basic principle of wet sandblasting is as follows. The grinding liquid (mixture of water and abrasive) in the grinding liquid tank is drawn to the sandblasting gun by a pump and is sprayed onto the target material by the action of compressed air in the sandblasting gun. The grinding fluid is recovered to the grinding fluid tank for recycling.
