Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether from natural high polymer refined cotton by a series of chemical treatment.In the construction industry, what is the main use of hydroxypropyl methyl cellulose?
1, cement mortar: make cement sand dispersion degree increase, greatly improve the plasticity of mortar and water retention, have a preventive effect on crack, can improve cement strength.
2, asbestos and other refractory coating: used as a suspension safety agent, improve the liquidity, but also increase the bonding strength of the matrix.
3, gypsum coagulant: 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 liquidity and water retention.
5, plaster: 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 coating and putty powder operation performance, improve its liquidity.
7, spraying: to prevent cement or latex system filling leakage, improve the flow and spray graphics has a very good effect.
8, cement, gypsum secondary products: as a hydraulic material such as cement - asbestos system of pressure forming binder, improve liquidity, can obtain uniform molding products.
9. Fiber wall: because of its antibacterial and enzyme resistance, it is very effective as a binder for sand wall.
10, gap cement: added to the gap cement, in order to improve the liquidity and water retention.
The above is the introduction of the use of hydroxypropyl methyl cellulose, we have a look!
