Properties Of Building Material Grade Cellulose Ether

The solubility properties of cellulose after etherification change significantly and can be dissolved in water, dilute acid, dilute alkali or organic solvents. The solubility mainly depends on three factors: (1) the characteristics of the groups introduced during the etherification process, The larger the introduced group, the lower the solubility, the stronger the polarity of the introduced group, and the easier it is for cellulose ether to dissolve in water; (2) The degree of substitution and the distribution of etherification groups in macromolecules. Most cellulose ethers can only be dissolved in water under a certain degree of substitution, which is between 0 and 3; (3) The degree of polymerization of cellulose ethers. The higher the degree of polymerization, the less soluble it is; the higher the degree of polymerization, the less likely it is to dissolve. The lower the degree of substitution, the wider the range of substitution degrees that can be dissolved in water. There are many varieties of cellulose ethers with excellent properties, and they are widely used in industries such as construction, cement, petroleum, food, textiles, detergents, coatings, medicine, papermaking, and electronic components.
