HPMC cellulose ether cement-based mortar

HPMC may serve as thickening agent, dispersant agent, emulsifying agent or film-forming agent, and its industrialized products may be applicable to the production of daily chemicals, synthetic resin, construction and coating materials.

1.Suspension Polymerization:

In the production of synthetic resin such as polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other copolymerisate, suspension polymerization is the most used and it requires to keep hydrophobic monomers to suspend in the water. HPMC product has excellent surface activity as a type of water-soluble polymer. In addition, it plays the role of colloidal protectant that it can delay the coacervation of particles. Furthermore, although HPMC is a type of water-soluble polymer, it is somewhat dissolvable in hydrophobic monomers and can enhance the monomer porosity for production of polymerizing particles, thus, it may render polymer good capacity for removal of residual monomers and absorption of plasticizer.

2.It is applicable to the production of following products in the recipe of construction materials.

1) Waterproof putty powder

2) Cement sand mortar

3) Cement base brick/tile and the bonding between tile and base brick

4) Plaster for gypsum board base

5) Cement-based structural plaster.
