Structure Formula :

Introduction

Where :R=-H , -CH3 , or -CH2CHOHCH3;X=degree of polymerization .

Abbreviation: HPMC

Characteristics

1. Water-soluble, non-ionic cellulose cellulose ether
2. Odorless, tasteless, non-toxic, white powder
3. Dissolved in cold water, forming a clear or slightly solution
4. Properties of thickening, binding, dispersing, emulsifying, film-forming, suspension, adsorption, gel, surface activity, water retention and protective colloid

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.

Application

1. Cement based plaster
(1) Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the introduction of air to eliminate cracks on the surface of the coating to form the desired smooth surface.
2. Gypsum-based plaster and gypsum products
(1) Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the uniformity of the consistency of the mortar to form the desired surface coating.
