Insulation cracks: Generally, irregular cracks are common. It is caused by many reasons such as shrinkage deformation of benzene board, mesh cloth, mortar, and incorrect construction. The solution should be based on the size and distribution of the crack. If it is serious,

Cellulose ether HPMC mainly plays a role of water retention and thickening in cement mortar and gypsum-based slurry, which can effectively improve the adhesion and sag resistance of the slurry.

The water retention of hydroxypropyl methyl cellulose ether decreased with the increase of temperature, and the fineness also requested that the particle size of 20~ 60 percent was smaller than 63um. The appearance immediately dissolved and formed the gel to wrap the material to prevent the water molecules from continuing to infiltrate,

In recent years, with the continuous development of external wall insulation technology, the continuous progress of cellulose production technology, and the excellent characteristics of HPMC itself, HPMC has been widely used in the construction industry. In order to understand the mechanism of HPMC and cement-based materials in depth, this article introduces the improvement effect of HPMC on the cohesive properties of cement-based materials.

Construction Industry: HPMC,As Cement mortar water-retaining agent, retarder so that mortar with pumping. In the plaster, Gypsum Material, putty powder or other building materials, as an adhesive, improve smear and extend the operating time.

Powder mixing method: the HPMC powder and a large number of other powdery material ingredients, fully mixed with a blender, after adding water to dissolve, then the HPMC can be dissolved at this time, without agglomeration, because each tiny little corner, only a little HPMC powder

In premixed mortar, only a little HPMC can significantly improve the performance of wet mortar, which shows that HPMC is a major additive affecting the construction performance of mortar.
Selection of different varieties,

All types HPMC can be directly added in the material as dry mixing method

HPMC is off-white powder in appearance. HPMC could dissolved in water and forms colloids. It is no-toxic.
