Hydroxypropyl methyl cellulose, is a nonionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer commonly used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicine.

First of all, the raw material for the preparation of PCE Powder is the mother liquor of polycarboxylic acid water-reducing agent, and the mother liquor prepared by each manufacturer is different. To study its principle, in addition to external factors such as environmental temperature and manual operation, the process of polymerization monomer is also different. Therefore, if a manufacturer cannot control the production of polycarboxylic acid mother liquor, he can only purchase the mother liquor with different performance from other manufacturers and the quality of each batch can not be guaranteed to spray powder, resulting in the quality of PCE Powde produced.

1. VAE Re dispersible Polymer Powder is a water-soluble redispersible powder, which can be divided into ethylene/vinyl acetate copolymer, vinyl acetate/ethylene tert carbonate copolymer, acrylic acid copolymer, etc. The powder adhesive made by spray drying uses polyvinyl alcohol as a protective adhesive.

Polycarboxylate superplasticizer is a concrete admixture with high water reducing rate and low slump loss.
