Hydroxypropyl methyl cellulose for construction purposes

"Weihong" construction dedicated hydroxypropyl methyl cellulose

Properties of hydroxypropyl methyl cellulose for construction purposes

Soluble in water and some organic solvents can dissolve in cold water, only the highest concentration depends on the viscosity, solubility with viscosity changes, viscosity is low, the solubility is higher.

The salt tolerance of the construction-specific hydroxypropyl methyl cellulose is non-ionic cellulose ether, not the polymer electrolyte, so in the presence of metal salts or organic electrolytes, in aqueous solution is relatively stable, but excessive electrolyte can cause gel and precipitation.

Because the surface activity of aqueous solution has the function of surface activity, it can be used as colloid protector, emulsifier and dispersant.

Curdlan Adhesive Building Dedicated hydroxypropyl methyl cellulose solution heated to a certain temperature, opaque, gel formation, precipitation, but after continuous cooling, return to the original solution, temperature and gel precipitation mainly depends on its lubricants, suspension additives, protective colloid, help emulsifier.

Fungi possess good drug resistance and have good viscosity stability in long-term preservation.

The viscosity stability of the ph-specific hydroxyl-propyl methyl cellulose solution is hardly influenced by the acid-base, and the ph value is relatively stable in the range of 3.0 ~ 11.0.

The shape-preserving water solution is made of a special hydroxypropyl methyl cellulose with a high concentration aqueous solution compared with other polymers, which has a special viscoelasticity, combined with the invariant shape extrusion of ceramic products, and improves its ability.

High viscosity water retaining construction dedicated hydroxypropyl methyl cellulose is hydrophilic, its aqueous solution is a high-performance water reducer.

Thickening agent, film forming agent, adhesive, lubricant, suspension agent, emulsifier, protective colloid and other characteristics.

The architectural superiority of hydroxypropyl methyl cellulose in the construction field

Performance：

1, the dry powder formula is easy to blend.

2, with cold water dispersion characteristics.

3, the solid particles are effectively suspended, making the mixture smoother and evenly.

Mixed：

Dry mixing formulations containing hydroxypropyl methyl cellulose can be easily blended with water.

2. Fast access to required consistency.

The dissolution of cellulose ether is quicker and no clumps.

Construction：

1, improve lubrication and plasticity, so as to improve mechanical processing, so that the construction of products more convenient and efficient.

2, improve water retention, prolong working hours.

3. Help to prevent the vertical flow of mortar, mortar and tiles. Lengthen the setting time and improve the working efficiency.

4, improve the bonding strength of ceramic tile adhesives.

5. Improve the cracking resistance and strength of mortar and plate joints sealant.

6, improve the air content in mortar, greatly reduce the likelihood of cracks.

7. Can increase the tile adhesive's anti-flow hanging performance.

8, with the use of chemical starch ether, the effect is better!
