Water retention action and principle of hydroxypropyl methylcellulose (HPMC)

Mainly play the role of water retention and thickening, can effectively improve the bond of paste Force and anti-vertical.Air temperature, temperature and air pressure speed and other factors will affect the volatilization speed of water in cement mortar and stone camp base products.HPMC

Therefore, in different seasons, there are some differences in the water retention effect of products with the same amount of hydroxypropyl methyl fiber toxicity. In specific construction, the water retention effect of slurry can be adjusted by increasing or decreasing the amount of HPMC.

The water retention of methyl cellulose ether under high temperature conditions is an important indicator to distinguish the quality of methyl cellulose ether.

HPMC

Excellent hydroxypropyl methyl cellulose series products can effectively solve the problem of water retention under high temperature.In the high temperature season, especially in the hot and dry areas and the thin layer construction of the sunny surface, high-quality is needed to improve the water retention of the slurry.High quality HPMC, the uniformity is very good, its methoxy group and hydroxy propanxy group are evenly distributed along the cellulose molecular

HPMC
