Tips on the use of hydroxypropyl methyl cellulose

About the use of hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose can be applied to various fields of building materials. The editor will explain the functions and effects of hydroxypropyl methyl cellulose one by one. Next, let's learn the following knowledge together with the editor~

1. The high water retention of building mortar and plastering mortar can fully hydrate cement and significantly improve the bonding strength of the mortar. At the same time, hydroxypropyl methyl cellulose can appropriately improve the tensile and shear strength, greatly improving the construction effect and improving work efficiency.

2. Water resistant putty mainly plays a role in water retention, adhesion, and lubrication in the putty, avoiding cracking and dehydration caused by rapid water loss. HPMC can also enhance the adhesion of the putty and reduce sagging to ensure smooth construction.

3. In the plastering gypsum series, hydroxypropyl methyl cellulose mainly plays a role in water retention, thickening, lubrication, and has a certain retarding effect. Hydroxypropyl methyl cellulose solves the problems of hollowing and insufficient initial strength during the construction process, which may also extend the working time.

4. The Cellulose ether products in the exterior wall insulation mortar mainly plays a bonding role and improves the strength of the material. Mortar is easier to cover, improves work efficiency, and has the effect of resisting sagging. The water retention performance of hydroxypropyl methyl cellulose can extend the working time of mortar, improve shrinkage and crack resistance, improve surface quality, and increase bonding strength.

5. The high water retention of ceramic tile adhesive eliminates the need for pre soaking or wetting the ceramic tile and substrate, thereby greatly improving the bonding strength. The construction time of this slurry is long, delicate, uniform, convenient to construct, and has good resistance to moisture migration.

6. In the latex paint industry, hydroxypropyl methyl cellulose can be used as a film-forming agent, thickener, emulsifier, and stabilizer, making the film have good wear resistance, leveling, and adhesion. The pH used to improve surface tension is qualitative and has good miscibility with organic solvents. Its high water retention performance gives it good smoothness.

That's all for the use of hydroxypropyl methyl cellulose. If you are interested in the content of the above article and would like to continue learning more about methyl cellulose and building materials, you can continue to follow our article.
