One of the most important applications of polymer-modified cement mortar is the application of thin-layer construction methods to tile. The specific process is as follows: the dry powder adhesive with the package is mixed with water on the spot,

Starch ethers are used in cement-based systems such as plastering, adhesives, and leveling layer to form functional surfaces both internally and externally. Plastering mortar is used to cover uneven parts of walls. They must have a strong and durable bond to the substrate. 

Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE), and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles.

What should I pay attention to when using hydroxypropyl methylcellulose?

The hydroxypropyl methylcellulose market continues to expand. Compared with European malls, China’s hydroxypropyl methylcellulose mall is still in its infancy. Whether it is production skills or equipment, it is relatively backward, as a new type of Industry,

Under the wet-mixture situation, RDP would improve the thickness and slipperiness of the mortar system. The characters of the polymer itself make a big difference on mortar’s cohesion and workability.
After Tile Adhesive dried, RDP would also enhance the adhesion on the smooth and compact surface, and improve the effect of sandstone’s interface air vent. With enough RDP dosage, it would form a film on the interface which makes Tile Adhesive be flexible by lower the elasticity modulus.

In winter, how to use hydroxypropyl methyl cellulose for external wall insulation construction.

MFFT is the lowest temperature which allows polymer particles in emulsion have enough activity for intercoagulation and continuous film forming. During films forming, the polymer particles have a closer arrangement. To form a continuous film, besides good dispersion emulsion, there is also the requirement of polymer particles deforming (which shows the pressure between particles forced by hydraulic pressure). Closer the particles be, stronger the pressure would become.

HPMC is white powder or granule made from highly pure cotton – cellulose by reaction of etherification. HPMC is characterized by water solubility, water retention, nonionic, stability of the PH value, surface activity, temperature reversible gelling properties, thickening property, film formability, lubrication property etc.,without any organs of animals, fat and other bioactive constituents.
