The use of hydroxypropyl methylcellulose in building decoration materials

Hydroxypropylmethylcellulose (HPMC) is an odorless, odorless, non-toxic milky white powder that can be dissolved in cold water to produce a completely transparent viscous aqueous solution. It has the characteristics of thickening, bonding, dispersion, emulsification, demulsification, floating, adsorption, adhesion, surface activity, moisturizing, and maintenance colloidal solution.

1. Lime mortar cement mortar

High water retention can make the concrete fully set. The compressive strength of bonds continued to rise. In addition, tensile and shear strength can be increased. Further improve the actual effect of construction and improve work efficiency.

2. Waterproof putty

The main function of cellulose ether in putty powder is to maintain moisture, bond and lubricate, prevent cracks or glue opening caused by excessive water shortage, improve the cohesiveness of putty powder, and reduce the suspension state of the construction site. Make the project construction more satisfactory and save human capital.

3. Interface agent

Mainly as an emulsifier, it can increase the strength and tensile strength, improve the surface coating, and improve the adhesion and bonding strength.

4. External wall insulation mortar

Cellulose ether plays an important role in bonding, improving strength, making cement mortar easy to coat, and improving efficiency. Increase the working time, improve the anti-shrinking and cohesion performance of cement mortar, improve the process performance, and increase the bonding compressive strength.

5. Tile glue

High-grade water properties do not need to pre-soak or wet ceramic tiles and subgrades, which can significantly improve their bonding strength. The mortar can be used for a long time, fine, well-proportioned, convenient for construction, and has strong anti-slip properties.

6. caulking agent pointing agent

The addition of cellulose ether has good edge adhesion, low shrinkage and high wear resistance, protecting basic materials from mechanical damage, and avoiding the adverse effects of water immersion on the entire building.

7. Self-leveling raw materials

The stable viscosity of cellulose ether ensures the good fluidity and self-leveling ability of cellulose ether, controls the water retention rate, makes cellulose ether solidify quickly, and reduces cracks and shrinkage.
