The main construction functions of cellulose ether
Hydroxypropyl methyl cellulose (HPMC) is widely used in our daily life, not only has a very obvious role in convenient construction, but also occupies a high position in the coating industry. Let's take a look at the four superpowers of hydroxypropyl methyl cellulose（HPMC）:
1.The use of HPMC with a high degree of substitution can improve and control the properties of water-based coatings. It can improve the viscosity, surface expansion force, gel temperature and the compatibility of organic additives, and can control the effect of bacteria on the coating in tropical regions.
2.Various viscosity hydroxypropyl methylcellulose coatings are excellent in abrasion resistance, high temperature resistance, bacterial degradation resistance, washing resistance and stability to acid and alkali.
3.HPMC with high degree of substitution has better resistance to bacterial attack than low degree of substitution, and has better viscosity stability in polyvinyl acetate thickener. Inappropriate cellulose ethers reduce coating viscosity during storage due to cellulose ether degradation.
4.The degree of substitution of cellulose ether is increased, and the resistance to bacterial attack is also enhanced.
The company introduced a large-scale automated production line from Germany, specializing in the production of redispersible polymer powder, hydroxypropyl methyl cellulose, sodium carboxymethyl cellulose, and polycarboxylic acid water reducer.
