Application of HPMC in Various Building Materials Products

High water retention can make cement fully hydrated and bond strength increased obviously, and tensile elongation and shear strength can be properly improved, construction effect and work efficiency can be greatly improved.

2) The function of HPMC in water resistant putty powder:
Cellulose ether is mainly used for water retention, bonding and lubrication in putty powder to avoid cracks and dehydration caused by too fast water loss. Meanwhile, it enhances the adhesion of putty, reduces the phenomenon of flow hanging in construction, and makes the construction more smooth.
3) The application of HPMC in the plastering gypsum series:
Cellulose ether plays a role of water conservation, lubrication and so on in gypsum series products, and has a certain retarding effect. It solves the problem of drum and train in the construction process and the initial strength can not reach, and the working time can be prolonged.

4) The role of HPMC in the interface agent:
It is mainly used as thickener, which can improve tensile strength and shear strength, improve surface coating, enhance adhesion and bond strength.
5) The application of HPMC in the external wall insulation mortar:
Cellulose ether plays an important role in bonding and strength increasing in this material. It is that sand will be easier to coating, improve working efficiency, and has anti vertical flow effect. High water retention performance can extend the working time of mortar, improve anti shrinkage and cracking resistance, improve surface quality and improve bond strength.
6) The application of HPMC in ceramic tile binder:
The higher water retention can not be soaked or wet in advance, and the bonding strength of the tiles and bases can be improved significantly. The slurry can be constructed for a long period, delicate, even and convenient for construction, and has good anti-moisture mobility.

7) The role of HPMC in caulking agent and groove sealer:
The addition of cellulose ether has good edge adhesion, low shrinkage and high wear resistance, which protects the base material from mechanical damage and avoids the influence of penetration on the whole building.
8) The application of HPMC in DC flat materials:
The stability of cellulose ether ensures good fluidity and self leveling ability. The control of water retention rate makes it solidify rapidly, reduce cracking and shrinkage
