Application:
External wall insulation system: Selecting the appropriate amount of HPMC can maximize the bonding strength and smooth construction of the bonding mortar, and improve work efficiency
Tile adhesive: HPMC's good water retention, enhanced adhesion, and high sag resistance improve the efficiency of tile bonding, which can greatly improve the workability of the adhesive, allowing longer open time and stronger adhesion. , to prevent the tiles from losing water too quickly and falling off, improving the bond strength and shear strength.
Putty powder for internal and external walls: The water retention of HPMC can prevent the putty powder from cracking due to drying too fast after batch scraping, enhance the strength after hardening, and facilitate batch scraping construction. .
Grout: HPMC provides suitable viscosity, good plasticity and easy construction.
Self-Leveling Mortar: Low viscosity HPMC resists settling, enhances flow, and is pumpable. Controls water retention and reduces cracking and shrinkage.
Gypsum-based plastering: HPMC retains the moisture in the mortar, allowing the gypsum to fully set, and its sag resistance allows the builder to apply thicker coats without causing building ripples.
Daily chemical washing: HPMC is an effective film former, binder, thickener, stabilizer and dispersing agent in daily chemical washing.
Performance
Hydroxypropyl methylcellulose (HPMC) is a natural polymer material as raw material.Nonionic cellulose ethers obtained by chemical processing. In the production of building materials, hydroxypropyl methyl cellulose ether is an indispensable additive. After adding HPMC, the following performance can be improved:
1. Water retention : enhance water retention, improve the rapid drying of cement mortar and dry powder putty
Insufficient hydration can cause poor hardening, cracking and other phenomena.
2. Workability : increase the plasticity of the mortar, improve the industriality of the construction of steamed coating,
Improve work efficiency;
3. Adhesion : due to the improved plasticity of the mortar, it can better bond the substrate and the substrate.
bond;
4. Anti-sag : due to its thickening effect, it can prevent the occurrence of slippage of mortar and adherends during construction.
