Why HEMC is the better choice than HPMC for manufacturing of Cement tile adhesive and Wall putty?

Water-retaining and Principle of HPMC

HPMC, which is uniformly reacted, has even distribution of methoxy and hydroxypropoxy groups and high water retention.

1, this method is suitable for the determination of the dynamic HPMC viscosity of non-Newtonian fluids (polymer solution, suspension, emulsion dispersion liquid or surfactant solution, etc.).

In dry mix mortar, Adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar.

Hydroxypropyl methyl cellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water.

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,
