Cellulose ether is a kind of cellulose derivative, could use in various applications based on its unique properties. HPMC hydroxypropyl methylcellulose and MHEC methyl hydroxy ethyl cellulose are most widely used in dry mix mortar industry, paint and coatings, detergent and oil drilling.

In dry mix mortar, Adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar.

1. Subject content and scope of application

HPMC Hydroxypropyl methyl cellulose in cement mortar and gypsum slurry, mainly play the role of water retention and thickening, can effectively improve the adhesion and sag resistance of slurry.

Hydroxypropyl methyl cellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water.

Determination of purity of HPMC hydroxypropyl methyl cellulose

Different dry powder mortar products have different performance requirements, and the dispersible polymer powder is required to provide suitable performance.

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.
