Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based.

Hydroxypropyl methylcellulose HPMC endows wet mortar with excellent viscosity, which can significantly increase the adhesion between wet mortar and the base layer, and improve the anti-sagging performance of mortar. in mortar. The thickening effect of cellulose ether can also increase the homogeneity and anti-dispersion ability of fresh cement-based materials

Product name: hydroxyethyl methyl cellulose HEMC

1. Mix redispersible polymer powder with water in a ratio of 1:5, stir evenly and let it stand for 5 minutes, then observe the sediment on the bottom layer. Generally, the less sediment, the better the quality of RDP.

Control joints are essentially deliberate cracks cut into concrete floors that allow for movement caused by temperature and moisture changes. Put another way, when the concrete does inevitably shrink and crack, it does so on a line (at the bottom of the control joint) instead of randomly across the slab. If left unfilled, control joints can become areas for dirt, debris, and moisture to collect and cause problems.

The general plan for the application effect of HPMC is as follows：

Hydroxypropyl methylcellulose HPMC is mainly used in the molding of cement mortar and gypsum products as a dispersant, thickener and binder in building treatment. It is used in cement mortar to increase its cohesiveness, reduce flocculation, improve viscosity and shrinkage,

In the use of building materials, hydroxypropyl methyl cellulose HPMC is a commonly used building material additive, hydroxypropyl methyl cellulose is widely used in industry, and has different types, hydroxypropyl methyl cellulose can be divided into For cold water instant type and hot melt type.

As a common building material, hydroxypropyl methylcellulose HPMC is more important in the construction industry. What are the main functions of hydroxypropyl methylcellulose?
