1. Use in putty
In putty powder, HPMC plays three major roles of thickening, water retention and construction.
Thickener: The cellulose thickener acts as a suspending agent to keep the solution uniform up and down and prevent sagging.
Construction: HPMC has a lubricating effect, which can make the putty powder have good construction performance.
2. Application of cement mortar
The mortar without adding water-retaining thickener has high compressive strength, but its water-retaining performance, cohesion performance, and softness are poor, the amount of bleeding is large, and the operating feel is poor, so it is basically unusable. Indispensable ingredient for mixing mortar. In general, choose to add hydroxypropyl methylcellulose or methylcellulose to the mortar, and the water retention rate can reach more than 85%. The method used in the mortar is to add water after mixing the dry powder. The cement with high water retention performance can be filled with water, the bonding strength is significantly improved, and the tensile and shear strength can be appropriately increased, which greatly improves the construction effect and improves work efficiency.
3. Application of ceramic tile bonding
Hydroxypropyl methylcellulose tile adhesive can save tile pre-soaking water;
Specifications are pasted and secure;
Low posting technical requirements for employees;
There is no need to fix it with crossed plastic clips at all, the paste will not fall off, and the bond is firm;
There is no excess mud in the gaps of the bricks, which can avoid the surface pollution of the bricks;
Several tiles can be pasted together, unlike construction cement mortar, etc.
4. Application of caulking and grouting agent
Adding cellulose ether can make the edge bonding performance is good, the shrinkage rate is low, and the abrasion resistance is strong, so as to protect the base material from mechanical damage and avoid the adverse effect of water infiltration on the overall structure.
