The role of Hpmc

Cold water instant HPMC can be used for putty powder, mortar, liquid glue, liquid paint and daily chemical products. Hot melt HPMC is usually used in dry powder products and directly mixed with dry powder for uniform application, such as putty powder and mortar. Hydroxypropyl methyl cellulose can be widely used to improve the performance of cement, gypsum and other hydrate building materials. In cement-based mortar, it can improve water retention, extend correction time and opening time, and reduce flow suspension.

Hydroxypropyl methyl cellulose can be used in the mixing and construction of building materials. The dry mixing formula can be quickly mixed with water to quickly obtain the required consistency. Cellulose ether dissolves faster without agglomeration. PMC can be mixed with dry powder in building materials. It has the characteristics of cold water dispersion, which can well suspend solid particles and make the mixture more delicate and uniform. In addition, it can enhance the lubricity and plasticity, increase the processability, and make the product structure more convenient. The water retention property is enhanced and the working time is longer, which helps to prevent the vertical flow of mortar and ceramic tiles, prolong the cooling time and improve the working efficiency.

Hydroxypropyl methyl cellulose improves the bonding strength of tile adhesive, improves the crack resistance of mortar and wood joint, not only increases the air content in mortar, but also greatly reduces the possibility of cracking. It can also improve the appearance of products, and enhance the anti sagging performance of tile adhesive.
