I. Product overview.
Hydroxypropyl Methylcellulose (HPMC) is a kind of nonionic cellulose ether prepared from cellulose, a natural macromolecule material, by a series of chemical processes. Hydroxypropyl methyl cellulose (HPMC) is a odorless, tasteless, non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. It has the properties of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, water retention and protective colloid.
II. Application of Building Materials.
1. Masonry mortar and plastering mortar
High water retention can make cement fully hydrated. The bond strength is increased obviously. At the same time, the tensile strength and shear strength can be improved appropriately. Greatly improve the construction effect and work efficiency.
2. Water-resistant putty
The main functions of cellulose ether in putty are water retention, bonding and lubrication, avoiding cracks or dedusting caused by excessive water loss, increasing the adhesion of putty, reducing the hanging phenomenon in construction, making construction more smooth and labor-saving.
3. Interfacial agents
Mainly used as thickener, it can improve the tensile strength and shear strength, improve the surface coating, enhance the adhesion and bond strength.
4. External wall insulation mortar
Cellulose ether plays an important role in bonding and increasing strength, which makes mortar easier to coat, improves work efficiency, and has anti-hanging ability. Higher water-holding capacity can prolong the working time of mortar, improve shrinkage and crack resistance, improve surface quality and improve bonding strength.
5. Tile adhesive
Higher water retention can significantly improve the bond strength without pre-soaking or wetting ceramic tiles and foundations. Slurry can be constructed in a long period, delicate, uniform, easy to construct, and has good slip resistance.
6. Joint filler
The addition of cellulose ether makes it have good edge adhesion, low shrinkage and high wear resistance. It protects the base material from mechanical damage and avoids the negative impact of water infiltration on the whole building.
7. Self-leveling materials
The stable viscosity of cellulose ether guarantees good fluidity and self-leveling ability, controls water retention rate to enable it to solidify quickly, reduces cracking and shrinkage.
