Hydroxypropyl methyl cellulose plays three roles in the putty powder: thickening, water retention and construction:

Hydroxypropyl methylcellulose for construction prevents excessive absorption of water by the substrate, and the water should be retained in the plaster as much as possible during the period when the gypsum is solidified.

Hydroxypropyl methylcellulose is now used in all walks of life. What kind of raw material is it?

Hydroxypropyl methylcellulose has its unique properties in the application of building materials, from mixing to dispersion to construction, as follows:

Tile adhesive is an adhesive specially used to bond tiles. According to its composition, different products are divided into: cement-based tile adhesive, paste emulsion adhesive and reactive resin adhesive. This section mainly introduces cement-based tile adhesive.

Fast drying: This is mainly related to the amount of gray calcium powder added (too large, you can appropriately reduce the amount of gray calcium powder in the putty formula) and the water retention rate of the fiber, and it is also related to the dryness of the wall.

1. The quality of hydroxypropyl methylcellulose produced in horizontal and vertical kettles

Hydroxypropyl methyl cellulose HPMC is one of the most commonly used additives in dry mortar. Cellulose ether plays an important role in dry mortar. After the cellulose ether in the mortar is dissolved in water, it guarantees gelation due to surface activity.

Soluble in water and some organic solvents

It is soluble in cold water, and its maximum concentration is only determined by viscosity. The solubility changes with viscosity. The lower the viscosity, the greater the solubility.
