Binder Raw Material Hpmc Pva Cement Additive

  In the construction industry,The HPMC as a water retaining agent and retarding agent for water and sediment, the sand slurry can be pumped.Use mortar, gypsum, putty powder or other building materials as adhesives to improve the applicability and prolong the operation time.Use as paste ceramic tile, marble, plastic adornment, paste enhancement agent, still can reduce cement dosage. Hydroxypropyl methylcellulose (HPMC) is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, and other industries.Methyl cellulose is a non - ionic cellulose ether produced by a series of chemical processes.Hydroxypropyl methyl cellulose is a kind of white powder that is odorless, tasteless and non-toxic, which can dissolve in cold water and form a transparent viscous solution.It is characterized by thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid. Redispersible emulsion powder is mainly applied for the dry mixed mortar of the construction industry, and is the important additive of dry mixed mortar.
