Application
1.Water reducer
Improve concrete's impermeability, frost resistance, and reduce bleeding. In addition to sugar, wood calcium contains retarding group hydroxyl (—OH) and ether bond (—O—) in its molecule, which can inhibit initial hydration, so it has a retarding effect. The retardation effect of wood calcium changes significantly with the decrease of temperature.
2.Refractory
When making refractory bricks and tiles, wood calcium is used as a dispersant and adhesive, which can significantly improve the operating performance, and has good effects such as water reduction, enhancement, and prevention of cracks.
3.ceramics
Calcium lignosulfonate is used in ceramic products, which can reduce the carbon content and increase the green strength, reduce the amount of plastic clay, have good mud fluidity, increase the yield by 70-90%, and reduce the sintering speed from 70 minutes to 40 minutes.
4.others
Feed binder mineral powder binder calcium lignosulfonate can also be used in refining aids, casting, pesticide wettable powder processing, briquette pressing, mining, beneficiation agent, road, soil, dust control, manufacturing Leather tanning leather filler, carbon black granulation, etc.
