HPMC(Hydroxypropyl MethylCellulose)In building materials, hydroxypropyl methyl cellulose can act as dispersing agents, thickeners and binders, and HPMC is mainly used in the molding of cement mortar and plaster products. With cement mortar, HPMC will increase adhesion, reduce flocculation, improve viscosity, shrinkage, and water retention, reduce the water loss of concrete surface, enhance the strength, and prevent the occurrence of cracks or weathering effects from water-soluble salts.
Hydroxy Propyl Methyl Cellulose is powder. Please store it under dry, ventilated and clean conditions, especially avoid direct sunlight and damped areas. After opening the bag, must use it as soon as possible. In the case that you can't use it up one time, keep the bag closed tightly.
Tang Zhi HPMC is a very important component in building materials. Our HPMC can provide better water retention, strength and adhesion to cement, lime and gypsum based products. HPMC powder was added to these construction materials can make them better performance and improve the work efficiency of construction workers.
HPMC has excellent homogeneity, and its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose chain, which increases the ability of the oxygen atoms on the hydroxyl and ether bonds to form hydrogen bonds with water, turning free water into bound water, thus effectively controlling the evaporation of water caused by high temperature, and achieving high water retention. HPMC can evenly and effectively disperse in cement mortar and gypsum-based mortar, and encapsulate all solid particles, and form a layer of wetting film, the water in the mortar gradually released for a long time, and react with inorganic cementitious materials so as to ensure the bond strength and compressive strength of the material.

Knowledge of the use of hydroxypropyl methyl cellulose,such as,
1. Used in the plastering mortar of construction mortar, the high water retention of hydroxypropyl methylcellulose can fully hydrate the cement, significantly increase the bond strength of the cement, and at the same time appropriately increase the tensile strength and shear of the cement Strength, greatly improving the construction effect and improving work efficiency.
2. In the water-resistant putty, hydroxypropyl methylcellulose mainly plays the role of water retention, bonding and lubrication, avoiding cracks and dehydration caused by excessive water loss, and at the same time enhancing the adhesion of the putty and reducing sag during construction This phenomenon makes the construction more smooth.
3. In the plaster series products, hydroxypropyl methylcellulose mainly plays the role of water retention, thickening and lubrication, and has a certain retarding effect at the same time, which solves the problems of hollowing, cracking and failure to reach the initial strength during the construction process , can extend the operating time.
4. In the external wall thermal insulation mortar, hydroxypropyl methylcellulose mainly plays the role of bonding and increasing the strength, so that the thermal insulation sand will be easier to coat, thereby improving work efficiency. High water retention performance can prolong the working time of thermal insulation mortar, improve shrinkage and crack resistance, and improve surface quality.
5. Among the tile adhesives, hydroxypropyl methylcellulose has high water retention, so that it is not necessary to pre-soak or wet the tiles and the base, and significantly improve the bonding strength of the tile adhesive, so that the slurry can last for a construction period Long, delicate, uniform, easy to construct, and has good anti-moisture property.
6. In latex paint, hydroxypropyl methylcellulose can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that the film has good wear resistance, leveling property and adhesion , Improve surface tension. The PH is qualitative, and the miscibility with organic solvents is also good. The high water retention performance makes it have good brushing and leveling properties.
