Products | Function and Application |
CMC Ceramic Grade | CMC is used for ceramic embryo, glazing pulp and colored glaze in ceramic industry. Addition: 0.03%-0.2% used in ceramic embryo; 0.05-0.2% used in glazing pulp; 1.4-4.0% used in colored glaze. |
CMC Paper Grade | In making paper, CMC is used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability. Addition: 0.3-1.5%. |
