Understand the role of hydroxypropyl methyl cellulose in putty powder. Redispersible latex powder has high bonding ability and unique properties, such as water resistance, workability and heat insulation. Therefore, their application range is still extremely wide.

In recent years, with the continuous development of external wall insulation technology, the continuous progress of hydroxypropyl methyl cellulose production technology, and the excellent characteristics of hydroxypropyl methyl cellulose HPMC itself, hydroxypropyl methyl cellulose HPMC has been widely used in the construction industry. In order to deeply explore the mechanism of hydroxypropyl methylcellulose HPMC and cement-based materials, this paper focuses on the improvement effect of HPMC on the cohesive properties of cement-based materials.

In dry-mixed ready-mixed mortar, the addition amount of hydroxypropyl methylcellulose hpmc is very low, but it can improve the performance of wet mortar and is a major additive that affects the construction performance of mortar.

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.The main raw materials of hydroxypropyl methylcellulose (HPMC) are refined cotton, methyl chloride, propylene oxide, and other raw materials and chemicals, such as caustic soda, acid, toluene, isopropanol.

The broad prospects of hydroxypropyl methylcellulose in the construction industry cannot be questioned. Its excellent thickening performance and water retention performance make its application in the construction industry not to be ignored. Now let's talk about the viscosity characteristics of the aqueous solution of hydroxypropyl methylcellulose:

Hydroxypropyl methylcellulose(HPMC)  is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, odorless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution.
