Hydroxyethyl Methyl Cellulose (MHEC) is used in cement mortar. It is a natural polymer cellulose made by a series of chemical treatments . Water-soluble white powder.
It can improve the cohesiveness and operability of mortar, overcome the common faults such as shell lifting and hollow drum of common mortar, reduce blanking, save material and reduce cost.
It has a certain retarding effect, can ensure the mortar can operate time, improve mortar plasticity and construction effect.
Cellulose ether MHEC is a combination of physical and chemical effects to play the role of water retention and thickening, prevent mortar in the later hydration process due to shrinkage caused by cracking, improve the service life of the building.
ADVANTAGE
It has thickened, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gel and protective colloid surface activity, and retains moisture and other characteristics .
