hpmc used for all kinds ready-mixed construction powder materials

1. Use in putty.
In the putty powder, HPMC plays the three major roles of thickening, water retention and construction.
Thickener: Cellulose thickener plays a suspending role to keep the solution uniform and up and down to prevent sagging.
Construction: HPMC has a lubricating effect and can make the putty powder have good construction performance.
2. Application of cement mortar.
The mortar without water-retaining thickener has higher compressive strength, but its water-retaining performance, cohesive performance, softness is poor, bleeding is large, and the operating feel is poor, so it cannot be used basically. Therefore, the water-retaining thickening material is expected An indispensable ingredient for mixing mortar. Under normal circumstances, adding hydroxypropyl methylcellulose or methyl cellulose to the mortar, the water retention rate can reach more than 85%. The method used in the mortar is to mix the dry powder and add water. Cement with high water retention properties 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 work efficiency.
3. the application of ceramic tile bonding
Hydroxypropyl methylcellulose tile adhesive can save tile pre-foaming water;
The specifications are pasted and firmly;
The posting technical requirements for employees are relatively low;

There is no need to fix with cross plastic clips at all, the paste will not fall off, and the bonding is firm; There is no excess mud in the cracks of the bricks, which can avoid the surface pollution of the bricks; Several tiles can be pasted together, not like a single piece of cement mortar.
