Competitive price Industrial grade methyl cellulose Ether HPMC thickener for gypsum plaster of Paris

Short Description:

Hydroxy propyl methyl cellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.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. In the course of construction,HPMC is used for wall putty, tile adhesive, cement mortar, dry mix mortar, wall plaster, skim coat, mortar, concrete admixtures, cement, gypsum plaster, joints fillers, crack filler, etc.

Product viscosity
Construction-grade crystalline cellulose for mortar (here refers to pure cellulose, excluding existing products) in terms of viscosity range
Generally, the following types are commonly used (the unit is viscosity)
Low viscosity: 400 is mainly used for self-leveling mortar, but it is generally imported.
Reason: The viscosity is low, although the water retention is poor, but the leveling property is good, and the mortar density is high.
Medium and low viscosity: 20000-40000 is mainly used for anti-cracking mortar, thermal insulation cement mortar, etc.
Reason: good construction, less water, high density of mortar.
Medium viscosity: 75000-100000 mainly used for putty
Reason: good water retention
High viscosity: 150000-200000 Mainly used for tile adhesive, caulking, polystyrene particle insulation agent, mortar glue powder and vitrified microspheres
Insulation mortar.
Reason: high viscosity, mortar is not easy to fall off, sagging, which improves the construction.
But generally speaking, the higher the viscosity, the better the water retention. Therefore, considering the cost, many dry powder mortar factories use medium
Viscosity cellulose (75000-100000) replaces medium and low viscosity cellulose (20000-40000) to reduce the amount added.

Application
