1. Hydroxypropyl methyl cellulose HPMC has stable chemical properties, mildew-proof and water-retaining effects in the glue, and is not affected by changes in pH. The viscosity can be used from 100,000 S to 200,000 S. However,

Accurate weighing and measurement of hydroxypropyl methyl cellulose samples, hydroxypropyl methyl cellulose cover the crucible half, calculate the content of iron salt content: the amount of plastic iron is 1000, the sample quality is measured several times and transferred to 50mL Volumetric flask to remove iron; accurately weigh 1～1.5g (accurate to 0.0001g) sample

1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. Used as a binder in plaster, plaster, putty powder or other building materials to improve spreadability and prolong operation time. It can be used as a paste tile, marble, plastic decoration, paste enhancer, and can reduce the amount of cement.

Cellulose products are all derived from natural cotton pulp or wood pulp, and are made through etherification. Different cellulose products use different etherifying agents. The etherifying agent used in hydroxyethyl cellulose (HEC) is ethylene oxide, and hydroxypropyl methylcellulose (HPMC) uses other types of etherifying agents.

The hydroxypropyl cellulose ether hpmc is provided with a water-repellent and thickening-imparting cellulose ether.
Redispersible polymer powder increasing the tile ceramic adhesion . It Vinyl acetate/vinyl ester copolymer, lauric acid ethylene/ethylene/vinyl chloride.

The tile adhesive /dry mortar must have strong adhesion between the cement base layer and ceramic tile ( wall tile and ground tile)

1. Air-entraining. Hydroxypropyl methyl cellulose ether hpmc has strong air-entraining properties, while hydroxypropyl starch ether has no air-entraining properties.

Hydroxypropyl content and viscosity, most users care about these two indicators. The higher the hydroxypropyl content, the better the water retention. Viscosity is higher, water retention is relatively (rather than absolute) is better, and viscosity is higher, it is better used in cement mortar.

Hydroxypropyl methyl cellulose (HPMC)
Application introduction:
1. Construction industry: As a water retention agent and retarder for cement sand slurry, the slurry is pumpable. Used as a binder in plastering plaster, gypsum material, putty powder or other building materials to improve the spreadability and extend the operating time. Used for pasting ceramic tiles, marble, plastic decoration
