Hydroxypropyl methylcellulose is divided into 2 kinds of ordinary hot-soluble cold water instant type.
1. Gypsum series In gypsum series products, cellulose ether is mainly used for water retention and smoothness. Together they provide some relief. It can solve the doubts about drum cracking and initial strength during construction, and prolong the working time.
2. In the putty of cement products, cellulose ether mainly plays the role of water retention, adhesion and smoothness, and prevents cracks and dehydration caused by excessive water loss. Together, they enhance the adhesion of the putty and reduce the occurrence of The drooping phenomenon, and make the construction more smoothly.
3, latex paint In the paint industry, cellulose ether can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that it has good wear resistance, uniform layer performance, adhesion and PH value, and has improved surface tension. Mixed well with organic solvents, high water retention gives excellent brushing and leveling.
4. The interface agent is mainly used as a thickener, which can increase the tensile strength and shear strength, improve the surface coating, and enhance the adhesion and bond strength.
5. Insulation mortar for external walls The cellulose ether in this article focuses on bonding and increasing strength, making the mortar easier to apply and improving work efficiency. Anti-sagging effect, higher water retention function can prolong the use time of mortar, improve the resistance to shortening and cracking, improve the surface volume and increase the bond strength.
6. Honeycomb ceramics In the new honeycomb ceramics, the product has smoothness, water retention and strength.
7. The addition of cellulose ether in sealants and sutures makes it have excellent edge adhesion, low reduction rate and high wear resistance, and protects the basic data from mechanical damage and prevents the impact of immersion on all constructions.
8. The stable adhesion of self-leveling cellulose ether ensures excellent fluidity and self-leveling ability, and the operating water retention rate enables it to set quickly and reduce cracking and shortening.
9. Construction mortar Plastering mortar with high water retention can fully hydrate the cement, significantly increase the bond strength, and at the same time appropriately increase the tensile and shear strength, greatly improving the construction effect and improving work efficiency.
10. The high water retention of the tile adhesive does not require pre-soaking or wetting of the tiles and the base layer, which significantly improves the bonding strength. The slurry construction period is long, the construction is fine and uniform, the construction is convenient, and it has excellent migration resistance.
