The cellulose ether is also known the rheology modifier, i.e., an additive used to adjust the rheological properties of fresh mortar. The main functions are as follows:

HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.

HPMC are widely used as thickener, emulsifier, film-former, stabilizers, suspension agents, binder, dispersing agent, protective colloids, etc in construction materials, food, pharma, paper making industry, printing, synthetic resins, ceramics, textiles, agriculture, etc.

Hydroxypropyl methyl cellulose in dry mortar, increase the amount of cellulose ether is very low, but can improve the wet mortar obvious function, construction function is a main agent mortar. Now, using hydroxypropyl methyl cellulose in dry mortar cellulose ether is hydroxypropyl methyl cellulose ether (HPMC).

Redispersible latex powder: enhancing the bonding strength for all substrates (especially non-porous substrates and large-size tiles; or pasted on the smooth surface and unstable substrates), increasing the tensile strength, reducing the elastic modulus, increasing the water retention, improving the workability, and reducing the permeability, etc.;

Hydroxypropyl methylcellulose (HPMC) is a type of nonionic cellulose ether made from natural high molecular materials through a series of chemical processes. With such favorable features as high water retention, good dispersancy, h

 Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and ethylene. It dissolves in water easily and quickly forms emulsion.

Air temperature, temperature and wind pressure can affect the moisture content of cement mortar and gypsum base. Therefore, in different seasons, adding HPMC the same amount of product water conservation effect there are some differences.

CMC and HPMC can be added to mortar to maintain moisture and thickening.As the dosage increases, the level of mortar will be reduced.CMC is an ionic cellulose ether that can react with the Ca (OH) 2 when added to the mortar.There is no obvious improvement in the water retention performance of CMC,
