Application Fields Of Hydroxypropyl Methylcellulose In Various Building Materials

Hydroxypropyl methylcellulose In dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive that affects the performance of mortar construction. The cellulose ether used in dry mortars is now primarily hydroxypropyl methylcellulose ether (HPMC). Hydroxypropyl methylcellulose plays a role in water retention, thickening and improving construction performance in dry mortar.

Hydroxypropyl methylcellulose application areas:

1. The high water retention of building mortar and plastering mortar can fully hydrate the cement and significantly increase the bonding strength. At the same time, the tensile strength and shear strength can be appropriately improved, the construction effect can be greatly improved, and the working efficiency can be improved.

2, water-resistant putty in the putty cellulose ether mainly plays the role of water retention, bonding and lubrication, to avoid cracks and dehydration caused by excessive water loss, while enhancing the adhesion of putty, reducing the phenomenon of sagging during construction, so that The construction is smoother.

3. Plastering gypsum series In the gypsum series products, cellulose ether mainly plays the role of retaining water, increasing lubrication, etc., and has a certain retarding effect, which solves the problem of drum cracking and initial strength during construction, and can prolong working time. .

4. The interface agent is mainly used as a thickener to improve tensile strength and shear strength, improve surface coating, enhance adhesion and bond strength.

5. External wall thermal insulation mortar cellulose ether plays a role in bonding and increasing strength in this material, which makes the mortar easier to coat, improves work efficiency, and has more anti-sagging effect, and higher water retention performance can be extended. The working time of the mortar improves the anti-shrinkage and crack resistance, improves the surface quality and improves the bond strength.

6, the higher water retention of the tile adhesive can not pre-soak or wet the tile and the base, significantly improve its bond strength, the slurry can be long, delicate, uniform, easy to construct, and has good resistance to run-off .

7. The addition of caulking agent and grouting agent cellulose ether has good edge adhesion, low shrinkage and high wear resistance, protects the base material from mechanical damage and avoids penetration to the entire building belt. The impact of coming.

8. The self-leveling material cellulose ether has stable cohesiveness to ensure good fluidity and self-leveling ability, and control water retention rate to enable rapid solidification and reduce cracking and shrinkage.
