Knowledge and application of hydroxypropyl methylcellulose HPMC

Low viscosity cellulose ethers are widely use in autorid leveling. Self-leveling is a very progressive ancestors of the ground groundbreaking skills, all the ground in the environment of very few construction staff natural leveling. Compare with the previous manual leveling process, flatness and groundbreaking speed have been greatly improve.

Since flat dry mixed sand slurry coaxed the hydroxypropyl methylmethyl cellulose excellent water retention. Due to the flow requirements mixing balanced sand slurry can be automatic flat on the ground. So the water material used is larger, add HPMC, and after it will control the appearance of water retention, water, after drying the strength of the ground is higher, shrinkage is small, greatly reduce the cracking. Hydroxypropane fiber improves paving efficiency.

Underwater anticrete concrete:

Binding: HPMC, as a high-performance binder, is use in pigments, paper making, tobacco products and ceramic products.

HPMC material can adjust the width of the index scale, products with different viscosity have different applications. Low viscosity products are mainly use for film materials. To improve the dissolution of tablets, for example, water solution viscosity should not be less than 3cp, 3cp, if less than 3 c p, the coating will not have enough strength. But the viscosity is not too large, otherwise not disintegration. High viscosity products can be mainly used as accessories for controlle release and slow release preparation.
