Application of hydroxypropyl methyl cellulose in various building materials products
Mortar and insulation
Hydroxypropyl methyl cellulose (HPMC) in building mortar plaster mortar use role
High water retention can make cement fully hydrated, significantly increase bond strength, and can appropriately improve tensile and shear strength, greatly improve the construction effect, improve work efficiency.
Use of hydroxypropyl methyl cellulose (HPMC) in water – resistant putty powder
The cellulose ether in putty powder is mainly used for water retention, bonding and lubrication, to avoid cracks and dehydration caused by excessive water loss, and to enhance the adhesion of putty, reduce the flow and hanging phenomenon in construction, so that the construction is relatively smooth.
Hydroxypropyl methyl cellulose (HPMC) in plaster plaster series of use role
In gypsum series products cellulose ether mainly plays the role of water retention, increase lubrication, and has a certain retarding effect, to solve the construction process of drum, initial strength can not reach the problem, can extend the working time.
Use of hydroxypropyl methyl cellulose (HPMC) in interfacial agent
Mainly used as thickening agent, can improve tensile strength and shear strength, improve surface coating, enhance adhesion and bond strength.
Use of hydroxypropyl methyl cellulose (HPMC) in exterior wall insulation mortar
Cellulose ether in this material focus on bonding, increasing the strength of the role, sand will be easier to coating, improve work efficiency, and has the effect of anti-vertical flow, high water retention performance can extend the working time of mortar, improve the anti-shrinkage and anti-cracking, improve the surface quality, improve the bond strength.
Use of hydroxypropyl methyl cellulose (HPMC) in ceramic tile binder
High water retention can not be pre-soaked or wet ceramic tile and base, significantly improve its bond strength, slurry construction cycle can be long, delicate, uniform, convenient construction, and has good moisture resistance.
Hydroxypropyl methyl cellulose (HPMC) in the use of caulking agent, seam agent
The addition of cellulose ether gives it good edge bonding, low shrinkage and high wear resistance, protecting the base material from mechanical damage and avoiding the impact of penetration on the whole building.
Application of hydroxypropyl methylcellulose (HPMC) in self-leveling materials
The stable cohesiveness of cellulose ether ensures good fluidity and self-leveling ability, and the control of water retention rate enables rapid solidification, reducing cracking and shrinkage.
