Hydroxypropyl methyl cellulose, referred to as cellulose (HPMC), is made of highly pure cotton cellulose as a raw material and is specially etherified under alkaline conditions. The whole process is completed under automatic monitoring and does not contain any Active ingredients such as animal organs and oils.
Cellulose HPMC has many uses, such as food, medicine, chemistry, cosmetics, kiln industry, etc. The following briefly introduces its application in the construction industry:
1. Cement mortar: improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and enhance the strength of cement;
2. Tile cement: improve the plasticity and water retention of pressed tile mortar, improve the adhesion of tiles, and prevent pulverization;
3. Coating of refractory materials such as asbestos: as a suspending agent, fluidity improving agent, and also improves the bonding force to the substrate;
4. Gypsum coagulation slurry: improve water retention and processability, and improve adhesion to the substrate;
5. Joint cement: added to joint cement for gypsum board to improve fluidity and water retention;
6. Latex putty: improve the fluidity and water retention of putty based on resin latex;
7. Stucco: As a paste that replaces natural products, it can improve water retention and improve the bonding force with the substrate;
8. Coatings: As a plasticizer for latex coatings, it can improve the operational performance and fluidity of coatings and putty powders;
9. Spraying paint: It has good effect on preventing the sinking of cement or latex spraying materials and fillers and improving fluidity and spray pattern;
10. Secondary products of cement and gypsum: used as an extrusion molding binder for hydraulic substances such as cement-asbestos, to improve fluidity and obtain uniform molded products;
11. Fiber wall: Due to the anti-enzyme and anti-bacterial effect, it is effective as a binder for sand walls;
12. Others: It can be used as air bubble retaining agent (PC version) for thin clay sand mortar and plaster operator.
