Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether made of natural polymer cotton by a series of chemical treatments. In the construction industry, what is the main use of hydroxypropyl methylcellulose?

1, cement mortar: to improve the degree of cement sand dispersion, greatly improve the plasticity and water retention of mortar, crack prevention, can improve cement strength.

2, asbestos and other refractory materials coating: used as suspension agent, improve the fluidity, but also increase the bonding strength of the matrix.

3, gypsum coagulant slurry: improve its water holding performance and processing performance, and increase the adhesion to the matrix.

4, latex putty: latex oil based on resin latex, improve fluidity and water retention.

5, stucco: as a slurry instead of natural substances, can improve water retention, increase with the base glue relay.

6, coating: used as latex coating plasticizer, can improve the operating performance of coating and putty powder, improve its liquidity.

7, spraying: to prevent cement or latex system and other filler leakage, improve the fluidity and spray pattern has a good effect.

8, cement, gypsum secondary products: as a hydrohard material such as cement – asbestos extrusion molding binder, improve fluidity, can obtain uniform molding products.

9, fiber wall: Because it has the effect of antibacterial and anti-enzyme, it is very effective as a binder for sand wall.

10, gap cement: add in gap cement to improve fluidity and water retention.

The above is the introduction of hydroxypropyl methyl cellulose use, we understand it!
