What are cellulose derivatives?

Cellulose derivatives are produced by esterification or etherification of hydroxyl groups in cellulose polymers with chemical reagents. According to the structural characteristics of the reaction products, cellulose derivatives can be divided into three categories: cellulose ethers, cellulose est... Read More

What are the differences between various types of cellulose?

Cellulose ether is a general term for a series of products produced by the reaction of alkali cellulose and etherifying agent under certain conditions. Alkali cellulose is replaced by different etherifying agents to obtain different cellulose ethers. According to the ionization properties of subs... Read More

The causes of bubbles and the advantages and disadvantages of bubbles during the application of cellulose ether products

The cellulose ether products HPMC and HEMC have both hydrophobic and hydrophilic groups. The methoxy group is hydrophobic, and the hydroxypropoxy group is different according to the substitution position. Some are hydrophilic and some are hydrophobic. Hydroxyethoxy is hydrophilic. The so-called h... Read More

The relationship between cellulose ether, magnesium aluminum silicate and ready-mixed mortar and dry powder mortar

In order to make the performance of all aspects of the ready-mixed mortar meet the specifications and construction requirements, the mortar admixture is an essential component. Magnesium aluminum silicate thixotropic lubricant and cellulose ether are commonly used water-retaining thickeners in mo... Read More
