Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. Has the properties of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface properties, retaining moisture and protective colloids. Hydroxypropyl methylcellulose, methylcellulose can be used in building materials, coating industry, synthetic resin, ceramics industry, medicine, food, textile, agriculture, daily chemical and other industries.
The main application of hydroxypropyl methylcellulose HPMC in building materials:
1 Cement-based plastering grout
①Improve uniformity, make plastering paste easier to trowel, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
②High water retention, prolong the placement time of the mortar, improve the work efficiency, and facilitate the hydration and solidification of the mortar to produce high mechanical strength.
③ Control the introduction of air to eliminate cracks on the coating surface and form an ideal smooth surface.
2 Gypsum-based plastering pastes and gypsum products
①Improve uniformity, make plastering paste easier to trowel, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
②High water retention, prolong the placement time of the mortar, improve the work efficiency, and facilitate the hydration and solidification of the mortar to produce high mechanical strength.
③ Control the consistency of the mortar to be uniform and form an ideal surface coating.
3 Masonry mortar
①Enhance the adhesion with the masonry surface, enhance the water retention, and improve the strength of the mortar.
②Improve lubricity and plasticity, and improve workability; the mortar improved by cellulose ether is easier to construct, saves construction time and reduces construction cost.
③Ultra-high water-retaining cellulose ether, suitable for high water-absorbing bricks.
4 plate joint filler
①Excellent water retention, prolong opening time and improve work efficiency. High lubricant, easier to mix.
②Improve shrinkage resistance and crack resistance, and improve the surface quality of the coating.
③Improve the adhesion of the bonding surface and provide a smooth and smooth texture.
5 Tile Adhesives
①Easy to dry mix the ingredients, no lumps will be produced, the application speed will be increased, the construction performance will be improved, the working time will be saved, and the working cost will be reduced.
②By extending the opening time, it improves the efficiency of tiling and provides excellent adhesion effect.
6 Self-leveling floor materials
① Provides viscosity and can be used as an anti-settling aid.
②Enhance the pumpability of fluidity and improve the efficiency of paving.
③ Control water retention and shrinkage to reduce cracks and shrinkage of the ground.
7 Water-based paint
①Prevent solid precipitation and prolong the container period of the product. High biological stability and excellent compatibility with other components.
②Improve fluidity, provide good splash resistance, sag resistance and leveling, and ensure excellent surface finish.
8 wallpaper powder
①Quickly dissolve without agglomeration, which is convenient for mixing.
②Provide high bond strength.
9 Extruded cement board
①It has high adhesion and lubricity, and enhances the processability of extruded products.
②Improve the green strength, promote the hydration and curing effect, and improve the yield.
10 HPMC products for ready-mixed mortar
The HPMC product specially used for ready-mixed mortar has better water retention than ordinary products in ready-mixed mortar, ensuring that the inorganic cementitious material is fully hydrated, and significantly preventing the reduction of bond strength caused by excessive drying and cracking caused by drying shrinkage. HPMC also has a certain air-entraining effect. HPMC products specially used for ready-mixed mortar have appropriate, uniform and small air-entrainment, which can improve the strength and plastering of ready-mixed mortar. The HPMC product specially used for ready-mixed mortar has a certain retarding effect, which can prolong the opening time of ready-mixed mortar and reduce the difficulty of construction.
