Cellulose ether, derived from natural cellulose, is a synthetic polymer obtained through chemical modification. The basic material is natural cellulose, which is a natural polymer compound. Due to the unique structure of natural cellulose, it lacks the ability to react with etherification agents. However, under the treatment of swelling agents, the strong hydrogen bonds inside […]
Using renewable raw materials such as camphene, cork flour, straw, rapeseed or sugar cane can reduce the share of fossil raw materials by up to 50%. The use of renewable raw materials in paint production makes a significant contribution to sustainability, as natural resources are conserved and the use of fossil raw materials is reduced. […]
Cellulose ether is generated from natural cellulose as the basic raw material through alkalization and etherification reactions. Cellulose has a highly crystalline structure that only swells and does not dissolve in water, so it does not react with etherification agents. However, through the swelling agent, the hydrogen bonds between cellulose molecules are broken, and the […]
Calcium formate is a common chemical substance widely used in fields such as food, agriculture, and industry. However, during storage and use, calcium formate may sometimes clump, which not only affects its effectiveness but may also cause certain economic losses. In order to better understand the causes of calcium formate agglomeration and find solutions, this […]
