What are the differences between Guangxi Longhua nano calcium carbonate and Guangxi Longhua active calcium carbonate? 1. Guangxi Longhua active calcium carbonate refers to calcium carbonate particles whose surface has been treated. Usually, modification is carried out using surface active agents or coupling agents such as stearic acid. Calcium carbonate particles are originally hydrophilic and lipophilic. After surface modification, they become lipophilic and hydrophobic, so they can be added to the processes of plastics and rubber and are compatible with oily resins.

Guangxi Longhua Nano calcium carbonate and Guangxi Longhua What are the differences between active calcium carbonate and nano calcium carbonate? 1, Guangxi Longhua Active calcium carbonate refers to calcium carbonate particles whose surface has been treated. Usually, it is modified with surface active agents or coupling agents such as stearic acid. Calcium carbonate particles are originally hydrophilic and oleophobic. After surface modification, they become lipophilic and hydrophobic, so they can be added to the processes of plastics and rubber, and are compatible with oily resins.

　　2, Guangxi Longhua Active calcium carbonate is an important filler and enhancer. Guangxi Longhua Active calcium carbonate is used as a base material. Multifunctional surface active agents and composite high-efficiency processing auxiliaries are used to modify and activate the surface of inorganic powders. After modification, a special coating structure is formed on the surface of the calcium carbonate powder, which can significantly improve the dispersibility and affinity in polymer matrices such as polyolefins, and can produce interfacial effects with the polymer matrix, thereby improving the impact strength of the product. It is a high-performance incremental filler. The filling amount is generally 30-100%, and some products even exceed 100 parts.
