How is sodium carboxymethylcellulose prepared?
Using cellulose as raw material, CMC-Na was prepared by a two-step method. The first is the alkalization process of cellulose. The cellulose reacts with sodium hydroxide to generate alkali cellulose, and then the alkali cellulose reacts with chloroacetic acid to generate CMC-Na, which is called e...Read more -
The quality of cellulose determines the quality of mortar
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more -
What are the types of cellulose ethers?
Classified according to substituents, cellulose ethers can be divided into single ethers and mixed ethers; classified according to solubility, cellulose ethers can be divided into water-soluble and water-insoluble. The main classification method of cellulose ether is to classify according to ioni...Read more -
What are the definitions of fiber, cellulose, and cellulose ether and what are the differences?
Putty powder is mainly composed of film-forming substances (bonding materials), fillers, water-retaining agents, thickeners, defoamers, etc. Common organic chemical raw materials in putty powder mainly include: cellulose, pregelatinized starch, starch ether, polyvinyl alcohol, dispersible latex p...Read more -
