The application of Hpmc used in putty powder

Hpmc can be used in putty powder,there are mainly four types of putty cracks. Insulation cracks: Generally, irregular cracks are common. It is caused by many reasons such as shrinkage deformation of benzene board, mesh cloth, mortar, and incorrect construction. The solution should be based on the size and distribution of the crack. If it [...]

What is the difference between cellulose ether and cellulose?

The nature of cellulose Cellulose is a macromolecular polysaccharide composed of D-1 glucose, which is composed of β-1,4 glycosidic bonds, and has a molecular weight of about 50,000 to 2,500,000, which is equivalent to 300 to 15,000 glucosyl groups. The formula can be written as (C6H10O5)n. It is the main component of vascular plants, lichens [...]
