pplication of hydroxypropyl methyl cellulose in various building materials products
First, the use of hydroxypropyl methylcellulose (HPMC) in construction mortar plastering mortar
High water retention can fully hydrate cement and significantly increase bond strength.
At the same time, the tensile strength and shear strength can be appropriately increased, which greatly improves the construction effect and the work efficiency.
Second, the use of hydroxypropyl methylcellulose (HPMC) in water-resistant putty powder
Cellulose ether in the putty powder mainly maintains water, bonds and lubricates to avoid cracks and dehydration caused by excessive water loss.
At the same time, the adhesion of the putty is enhanced, the sagging phenomenon during construction is reduce, and the construction is smoother.
Third, the use of hydroxypropyl methylcellulose (HPMC) in stucco plaster series
In the gypsum series products, cellulose ether mainly plays a role of water retention and increased lubrication.
At the same time, it has a certain retarding effect, which solves the problem of drums being lay out and the initial strength cannot be reach during the construction process, which can extend the working time.
Fourth, the use of hydroxypropyl methylcellulose (HPMC) in interfacial agents
It is mainly use as a thickener, which can improve the tensile strength and shear strength, improve the surface coating, enhance adhesion and bond strength.
Fifth, the use of hydroxypropyl methylcellulose (HPMC) in exterior insulation mortar
Cellulose ether in this material focuses on the role of bonding and increasing strength. Sand will be easier to coat and improve work efficiency.
At the same time, it has anti-sagging effect and higher water retention performance can prolong the working time of the mortar. Improve shrinkage and crack resistance, improve surface quality, and improve bond strength.
Sixth, the use of hydroxypropyl methyl cellulose (HPMC) in tile adhesives
Higher water retention eliminates the need to pre-soak or wet the tiles and base. So significantly improve its bonding strength, the slurry can be use for a long, fine, uniform and convenient construction. It also has good anti-moisture properties.
