Hydroxypropyl methylcellulose is easily soluble in cold water, but hot water will dissolve it. However, its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also much better than methyl cellulose.

Putty powder is generally 100,000 yuan, but the mortar is more demanding, and it takes 150,000 yuan to work. Moreover, the most important role of HPMC is water retention, followed by thickening. In putty powder, as long as the water retention is good and the viscosity is lower (70,000-80,000),

In the ready-mixed mortar, the addition amount of HPMC is very low, but it can significantly improve the performance of the wet mortar and is a major additive that affects the construction performance of the mortar.

Let’s first analyze the common quality problems of redispersible latex powder, as well as the common methods and harms of poor manufacturers to reduce costs:
How to distinguish or distinguish the quality of redispersible latex powder? To find a way, start with analysis:

The film of redispersible latex powder is elastic and tough, and it is in the rigid framework formed by the hydration of cement mortar. Between cement mortar particles and particles, it has a function similar to a movable joint, which can withstand high deformation loads, reduce stress, and improve tensile and bending resistance.

The transparency and performance of hydroxypropyl methyl cellulose are relatively stable. The performance requirements of hydroxypropyl methyl cellulose have relatively different requirements. For example, what is the solubility of hydroxypropyl methyl cellulose products?

When it comes to redispersible latex powder, we can think of its film-forming effect and adhesion, so is it really all Are they all film-forming?
Redispersible latex powder is a polymer emulsion through spray drying, freeze drying or spin flash evaporation

External thermal insulation system-choosing an appropriate amount of HPMC can maximize the bonding strength and smooth construction of the bonding mortar, and improve work efficiency.

Tile adhesive-HPMC’s good water retention, enhanced adhesion,

Hydroxypropyl methyl cellulose is a propylene glycol ether of methyl cellulose, in which both hydroxypropyl and methyl are combined with the anhydrous glucose ring of cellulose by ether linkages. It is a non-ionic cellulose ether and is easily dispersed in In cold water, the solution can form a thin film after drying. The aqueous solution is characterized by a pseudoplastic fluid and has the effect of mixing. After heating, a reversible thermal gel is formed.
