Application of hydroxypropyl methyl cellulose HPMC in buildin
Application of hydroxypropyl methyl cellulose HPMC in building materials
Hydroxypropyl methylcellulose (HPMC) is nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, tasteless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gel, surface, moisture retention and protective colloid. HPMC, MC can be used in construction materials, coatings industry, synthetic resin, ceramic industry, pharmaceuticals, food, textile, agriculture, daily chemical and other industries.
Cement based plaster
a> Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
b> High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength produced by the mortar hydration and solidification.
c> Control the introduction of air to eliminate cracks on the surface of the coating to form an ideal smooth surface
Gypsum based plaster and gypsum products
a> Improve uniformity, make plaster easier to smear, improve sag resistance, enhance fluidity and pumpability, and improve work efficiency.
b> High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength produced by the mortar hydration and solidification.
c> Control the uniformity of the consistency of the mortar to form the ideal surface coating.
Masonry mortar
a> Enhance the adhesion to the masonry surface, enhance water retention, and increase the strength of the mortar.
b> Improve lubricity and plasticity, improve workability; use mortar improved by cellulose ether, which is easier to construct, saves construction time and costs.
c> High water retention cellulose ether suitable for high water absorption bricks.
Tile adhesive
a> It is easy to mix dry ingredients, no agglomeration, improve application speed and construction performance, save working time and cost.
b> Improve the efficiency of tiling by extending the opening time and provide excellent adhesion.
Self-leveling floor materials
a> Provide viscosity as an anti-settling agent.
b> Enhance the pumpability of fluidity and improve the efficiency of paving the ground.
c> Control water retention and shrinkage, reducing cracking and shrinkage on the ground.
Water-based paint
a> Prevent solid precipitation and extend the container period of the product. High biostability and excellent compatibility with other components.
b> Improve fluidity; provide good spatter resistance, sag resistance and leveling to ensure excellent surface finish.
Wallpaper powder
a> Quickly dissolve without agglomeration, which is good for mixing.
b> Provide high bond strength.
Extruded cement sheet
a> It has high adhesion and lubricity, which enhances the workability of extruded products.
b> Improve green strength, promote hydration curing effect, and improve yield.
hydroxypropyl methyl cellulose HPMC products for premixed mortar
The HPMC product for premixed mortar has better water retention in the ready-mixed mortar than the ordinary product, ensuring that the inorganic cementing material is fully hydrated, significantly preventing the bond strength from being lowered due to excessive drying, and cracking caused by drying shrinkage. HPMC also has a certain venting effect. The HPMC product for premixed mortar has a proper amount of venting, uniformity and small bubbles, which can improve the strength and smooth of the ready-mixed mortar. The HPMC product specially used for ready-mixed mortar has a certain retarding effect, which can extend the opening time of the ready-mixed mortar and reduce the construction difficulty.
