Methods to identify the quality of VAE Re-dispersible Polymer Powder

VAE Re-dispersible Polymer Powder formed polymer film has good flexibility. The film is formed on the gap and surface of cement mortar particles to form a flexible connection. Thus, the brittle cement mortar becomes elastic. Mortar with redispersible emulsion powder is several times higher in tensile resistance than ordinary mortar.

Improvement effect of hydroxypropyl methyl cellulose on cement-based materials

In recent years, with the continuous development of external insulation technology, hydroxypropyl methyl cellulose production technology progress, as well as hydroxypropyl methyl cellulose HPMC itself has excellent characteristics, hydroxypropyl methyl cellulose HPMC in the construction industry has been widely used. In order to investigate the interaction mechanism between HPMC and cement-based materials, this paper focuses on the improvement effect of HPMC on the cohesion of cement-based materials.

Basic details of VAE Re-dispersible Polymer Powder

1. VAE Re dispersible Polymer Powder is a water-soluble redispersible powder, which can be divided into ethylene/vinyl acetate copolymer, vinyl acetate/ethylene tert carbonate copolymer, acrylic acid copolymer, etc. The powder adhesive made by spray drying uses polyvinyl alcohol as a protective adhesive.

How HPMC helps construction

High-quality HPMC can be evenly and effectively dispersed in cement mortar and gypsum based products, and wrap all solid particles, and form a layer of wetting film. The moisture in the base is gradually released over a long period of time, and hydrates with inorganic cementitious materials, thus ensuring the bonding strength and compressive strength of the materials. Therefore, in high temperature summer construction, in order to achieve the water retention effect, it is necessary to add enough high-quality HPMC products according to the formula, otherwise, quality problems such as insufficient hydration, strength reduction, cracking, hollowing and falling off caused by drying too fast will occur, and the construction difficulty of workers will also be increased. As the temperature decreases, the amount of HPMC can be gradually reduced, and the same water retention effect can be achieved.
