In the use of building materials, hydroxypropyl methylcellulose is a more commonly used building material additive, and hydroxypropyl methylcellulose is widely used in industry and has different types. Hydroxypropyl methylcellulose can be divided into cold water instant type and hot melt type, cold water instant HPMC can be used in putty powder, mortar, liquid glue, liquid paint and daily chemical products; hot melt HPMC is usually used in dry powder products, and Mix directly with dry powders such as putty powders and mortars for an even application.

Hydroxypropyl methylcellulose can be widely used to improve the performance of cement, gypsum and other hydrated building materials. In cement mortar, it can improve water retention, prolong correction time and open time, and reduce flow suspension phenomenon.

Hydroxypropyl methylcellulose can be used in the mixing and construction of building materials, and the dry mix formula can be quickly mixed with water and the desired consistency can be obtained quickly. Cellulose ether dissolves faster and without agglomeration, propylmethylcellulose can be mixed with dry powder in building materials, it has the characteristics of dispersing in cold water, which can suspend solid particles well and make the mixture more fine and uniform .

In addition, it can enhance the lubricity and plasticity, increase the workability, make the product structure more convenient, strengthen the water retention function, prolong the working time, help prevent the vertical flow of mortar, mortar and tiles, and extend the cooling time , to promote work efficiency.

Hydroxypropyl methylcellulose improves the bonding strength of tile adhesives, improves the crack resistance of mortar and wood board adhesives, not only increases the air content in the mortar, but also greatly reduces the possibility of cracking, and also improves Improve the appearance of the product and enhance the anti-sag performance of the tile adhesive.
