Product Description

 

Overview of brown cordum sand

Brown Corundum grain size sand is generally F12-F220 single sand, such as F12, F30, F54, F90, F100, F220 and other specifications of brown corundum single sand, mainly used in abrasive and other industries. It has a variety of excellent characteristics, such as brown corundum acid and alkali corrosion resistance, and good toughness, in which some adhesive can be used to make the grinding wheel; brown corundum crystallization is better, will not occur differentiation, cracking and blasting, can be used as refractory materials; and does not affect the color of the processing parts, can be used in prohibited iron powder residue sandblasting, powder level is very suitable for wet sandblasting and polishing work, fast processing speed and high quality, the amount of iron oxide is suitable for prohibited iron residual sandblasting operation, after pickling steps to remove impurities and other advantages.
