The main application of hydroxypropyl methylcellulose HPMC in building materials:
1. Cement-based gypsum
1) Improve uniformity, make mortar easier to construct, improve sag resistance, increase fluidity and pumpability, and improve work efficiency.
2) High water retention, extending the mortar pouring time, improving work efficiency, conducive to the hydration of the mortar, and producing high mechanical strength.
2. Gypsum-based gypsum and gypsum products
1) Improve uniformity, make mortar easier to construct, improve sag resistance, increase fluidity and pumpability, and improve work efficiency.
2) High water retention, extending the mortar storage time, improving work efficiency, conducive to the hydration of the mortar, and producing high mechanical strength.
3. Masonry mortar
1) Enhance the adhesion to the masonry surface, enhance the water retention, and increase the strength of the mortar.
2) Improve lubricity and plasticity, improve processability; use cellulose ether to improve mortar, which is easier to construct, save construction time and reduce construction cost.
4. Board joint filler
1) Excellent water retention, extending open time and improving work efficiency. High lubricant, easier to mix.
2) Improve shrinkage resistance and crack resistance, and improve the surface quality of the coating.
3) Improve the adhesion of the bonding surface to provide a smooth and smooth texture.
5. Tile adhesive
1) Easy to dry the mixed ingredients, no bulk, increase application speed, improve construction performance, save man-hours, and reduce work costs.
2) Improve tiling efficiency by providing longer open time and providing excellent adhesion.
6. Self-leveling floor material
1) Provide viscosity and can be used as anti-settling agent.
2) Improve fluid pumping capacity and improve the efficiency of laying the ground.
7. Water-based paint
1) Prevent solid precipitation and extend the shelf life of the product. High biological stability and excellent compatibility with other components.
2) Improve fluidity, provide good splash resistance, sag resistance and leveling, and ensure excellent surface finish.
