The water retention property of mortar refers to the ability of mortar to retain water. Mortar with poor water retention property is easy to bleed and segregate during transportation and storage, that is, water floats above and sand and cement sink below. It must be remixed before use.

The molecular weight of HPMC can be expressed by its solution viscosity in the solvent used.

How to improve adhesion of mortar？

1. Low-strength grade mortar, such as cement mortar, due to poor cement mortar workability.which is difficult to squeeze the mortar during masonry.

China’s cellulose ether production, processing and consumption in the world’s leading position.

The important role of water-soluble hydroxypropyl methyl cellulose ether in mortar is mainly in three aspects, one is excellent water retention capacity, the other is the effect on the consistency and thixotropy of mortar, and the third is the interaction with cement.

Redispersible polymer powder(RDP) is a water-soluble redispersible powder, which is a polymer of butadiene and vinyl acetate, and uses acrylic emulsion as a maintenance colloid solution. Therefore, RDP is very popular in the construction industry sales market, and the inappropriate use of RDP leads to unsatisfactory actual effects of engineering construction.
