Product Application

1. good surface cleaning performance:
Sandblasting the surface treated without insert, no unfavorable convex pointed and potholes, easily get clear SA3 highest level; the surface roughness can reach 30-80 microns, achieve better coating

adhesion and longer service life.

2. lowest economic cost :

excellent toughness, low brittleness, low breakage rate in the process of sandblasting, depending

on the applications of different recycled 5-10 times, further reduce the cost of the customer.

3. Good working environment:

Garnet abrasive blasting, the production process after 6 times washing, dust content is very low, 

4. Health, safety, environmental protection:

Garnet sandblasting abrasive, excluding free silicon, heavy metals and other harmful ingredients, no radiation, no health or environmental risks.

5. natural nonmetallic abrasive;

almost all the surface of the material can be used for pretreatment, especially suitable for carbon steel, stainless steel, aluminum, galvanized parts, copper, alloy, glass, stone, wood, rubber sand-blasting processing.
