Grinding wheel cutting parts usually use certain colorants to increase the color of the grinding parts. On the one hand, it is for aesthetics; on the other hand, it can protect the cutting parts of the grinding wheel and improve the light resistance and high temperature resistance of the grinding parts. Today we will talk about the types of colorants used in the cutting parts of the grinding wheel.
1. Iron oxide red, short for iron red, commonly known as Sudan, is a cheap red colorant with strong hiding power and tinting power. It has excellent light resistance, high temperature resistance, resistance to atmospheric influences, resistance to polluted gases, and resistance to all alkalis. Due to the different manufacturing methods and process conditions, the crystal state and composition of the structure are different, and the color and light of the cutting parts of the grinding wheel are very different. Pay attention when using it.
2. Chrome oxide green, referred to as chrome green, the color range introduced by the grinding wheel cutting machine manufacturer ranges from bright green to dark green. High temperature resistance, light resistance, resistance to various chemical solvents.
3. Iron oxide black, short for iron black, black powder, is an adduct of iron oxide and ferrous oxide. Manufacturers of abrasive cutting machines believe that it has a saturated bluish-black color, has high hiding power and tinting power, but is not as good as carbon black. It is stable to sunlight and atmosphere, resistant to all alkalis, but soluble in acid.
4. Carbon black, light and very fine black powder, the main component is elemental carbon, containing a small amount of oxygen, hydrogen, sulfur, etc. Insoluble in various solvents.
5. Titanium dioxide, commonly known as titanium dioxide or titanium dioxide, white powder, is a white pigment with strong tinting power. Manufacturers of grinding wheel cutters believe that it has excellent hiding power and color fastness, good light stability, and non-toxic.
