Insulation cracks: Generally, irregular cracks are common. It is caused by many reasons such as shrinkage deformation of benzene board, mesh cloth, mortar, and incorrect construction. The solution should be based on the size and distribution of the crack. If it is serious,

Cellulose ether HPMC mainly plays a role of water retention and thickening in cement mortar and gypsum-based slurry, which can effectively improve the adhesion and sag resistance of the slurry.

Hydroxypropyl methylcellulose (HPMC) is a kind of odorless, tasteless, non-toxic white powder. After fully dissolved in water, HPMC will form a transparent viscous colloid.

Internal and external wall putty powder, ceramic tile binder, ceramic tile sewing agent, dry powder interface agent, external wall external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external thermal insulation dry mixed mortar.

As we all know, the theory of cement’s complete hydration theory requires 26% of the cement’s mass, and the actual water consumption of the mortar greatly exceeds the moisture required for the cement’s hydration in the mortar,

The water retention of hydroxypropyl methyl cellulose ether decreased with the increase of temperature, and the fineness also requested that the particle size of 20~ 60 percent was smaller than 63um. The appearance immediately dissolved and formed the gel to wrap the material to prevent the water molecules from continuing to infiltrate,

At present, redispersible latex powder is widely used in concrete due to its good storage stability, storage period, no deterioration due to freezing or water volatilization, simple packaging, convenient transportation, and can be mixed with cement, gypsum and other raw materials at will.

Redispersible polymer powder is water-soluble redispersible powders. It is divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., and is powder bonded after spray drying.

In recent years, with the continuous development of external wall insulation technology, the continuous progress of cellulose production technology, and the excellent characteristics of HPMC itself, HPMC has been widely used in the construction industry. In order to understand the mechanism of HPMC and cement-based materials in depth, this article introduces the improvement effect of HPMC on the cohesive properties of cement-based materials.
