Hydroxypropyl methylcellulose model difference

Hydroxypropyl methyl cellulose is divided into 2 kinds of ordinary hot-dissolving cold water instant type.

1. Gypsum series In gypsum series products, cellulose ethers are mainly used to retain water and increase smoothness. Together they provide some relief. It can solve the doubts of drum cracking and initial strength during the application process, and prolong the working time.

2. In the putty of cement products, cellulose ether mainly plays the role of water retention, adhesion and smoothness, preventing cracks and dehydration caused by excessive water loss, and they together enhance the adhesion of the putty and reduce the occurrence of the construction process. sag phenomenon, and make the construction more smoothly.

3. In the coating industry of latex paints, cellulose ethers can be used as film-forming agents, thickeners, emulsifiers and stabilizers, so that they have good wear resistance, uniform layer performance, adhesion and PH value, and have improved surface tension. It also works well when mixed with organic solvents, and its high water retention makes it excellent for brushing and leveling.

4. The interfacial agent is mainly used as a thickener, which can improve the tensile strength and shear strength, improve the surface coating, and enhance the adhesion and bonding strength.

5. The cellulose ether in this paper focuses on bonding and increasing strength, making the mortar easier to apply and improving work efficiency. Anti-sag effect, higher water retention function can prolong the service time of the mortar, improve the resistance to shortening and cracking, improve the surface quantity and improve the bond strength.

6, Honeycomb ceramics In the new honeycomb ceramics, the product has smoothness, water retention and strength.

7. The increase of sealant, suture cellulose ether makes it have excellent edge adhesion, low reduction rate and high wear resistance, and protect the underlying data from mechanical damage, preventing the impact of soaking on all construction.

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. Building mortar plastering mortar has high water retention to fully hydrate the cement, significantly increase the bond strength, and at the same time appropriately increase the tensile and shear strength, which greatly improves the construction effect and improves the work efficiency.

10. The high water retention of the tile adhesive does not require pre-impregnation 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 anti-migration.
