The Importance of Water Retention of HPMC
April 24th 2024
Hydroxypropyl methyl cellulose (HPMC) in construction plastering mortar
High water retention can make cement fully hydrated, significantly increase bond strength, and can appropriately improve tensile strength and shear strength, greatly improve the construction effect, improve work efficiency.
Hydroxypropyl methyl cellulose (HPMC) in water – resistant putty powder
In putty powder cellulose ether mainly from water retention, bonding and lubrication, to avoid the phenomenon of cracks and dehydration caused by too fast loss of water, and enhance the adhesion of putty, reduce the phenomenon of flow hanging in the construction, so that the construction is relatively smooth.
Hydroxypropyl methyl cellulose (HPMC) in the use of plaster series
In gypsum series of products, cellulose ether mainly plays the role of water retention, increase lubrication and so on, and has a certain effect of retarding, to solve the problem of drum list in the construction process, initial strength can not reach, can prolong the working time.
Hydroxypropyl methyl cellulose (HPMC) in the use of interface agent
Mainly used as thickener, it can improve tensile strength and shear strength, improve surface coating, enhance adhesion and bond strength.
Hydroxypropyl methyl cellulose (HPMC) in the external wall insulation mortar function
Cellulose ether in this material focus on bonding, increase the strength of the role, is the sand will be easier to coating, improve work efficiency, at the same time with vertical flow resistance, high water retention performance can prolong the working time of mortar, improve the anti shrinkage and anti cracking, improve surface quality, improve bond strength.
Hydroxypropyl methyl cellulose (HPMC) in ceramic tile binder
High water retention can not pre-soak or wet ceramic tile and base, significantly improve its bond strength, slurry can be long construction cycle, delicate, uniform, convenient construction, and has good resistance to moisture.
Hydroxypropyl methyl cellulose (HPMC) in the caulking agent, groove seam agent
The addition of cellulose ether makes it have good edge adhesion, low shrinkage and high wear resistance, protect the base material from mechanical damage, avoid the impact of infiltration to the whole building.
Application of hydroxypropyl methyl cellulose (HPMC) in self leveling materials
Cellulose ether stable bond to ensure good liquidity and self-leveling ability, control water retention rate so that it can quickly solidify, reduce cracking and contraction.
