Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials
Hydroxypropyl methylcellulose (HPMC) is made from natural polymer material cellulose.
A nonionic cellulose ether produced by a series of chemical processing. And they are an odorless, tasteless, non-toxic white powder. Swell in cold water into a clear or slightly turbid colloidal solution.
Therefore, it has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, surface property, moisture retention and protective colloid.
Hydroxypropyl methylcellulose, methyl cellulose can be used in construction materials, coatings industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical and other industries.
The main application of hydroxypropyl methylcellulose HPMC in building materials:
1 cement based plaster
(1) Improve the uniformity, make the plaster more easy to smear, improve the sag resistance, enhance the fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the introduction of air to eliminate cracks on the surface of the coating to form the desired smooth surface.
2 gypsum based plaster and gypsum products
(1) Improve the uniformity, make the plaster more easy to smear, improve the sag resistance, enhance the fluidity and pumpability, and improve work efficiency.
(2) High water retention, prolonging the placement time of the mortar, improving work efficiency, and facilitating the high mechanical strength of the mortar hydration and solidification.
(3) Control the uniformity of the consistency of the mortar to form the desired surface coating.
3 masonry mortar
(1) Enhance the adhesion to the masonry surface, enhance water retention, and increase the strength of the mortar.
(2) Improve lubricity and plasticity, improve work ability; use mortar improved by cellulose ether, easier to construct, save construction time and reduce construction costs.
(3) Extra high water retention cellulose ether for high water absorption bricks.
4 plate joint filler
(1) Excellent water retention, extended open time and improved work efficiency. Highly lubricious and easier to mix.
(2) Improve shrinkage resistance and crack resistance and improve coating surface quality.
(3) Improve the adhesion of the bonding surface to provide a smooth, smooth texture.
5 tile adhesive
(1) It is easy to dry mix ingredients, no clumps, improve application speed. improve construction performance, save working time and reduce work cost.
(2) Improve the efficiency of tiling by extending the opening time and provide excellent adhesion.
6 self-leveling floor materials
(1) Provide viscosity as an anti-settling aid.
(2) Enhance the pumpability of fluidity and improve the efficiency of paving the ground.
(3) Control water retention and shrinkage, reducing cracking and shrinkage on the ground.
7 water-based paint
(1) Prevent solid precipitation and extend the container period of the product. High biostability with excellent compatibility with other components.
(2) Improve fluidity, provide good spatter resistance, sag resistance and leveling to ensure excellent surface finish.
8 wallpaper powder
(1) Quickly dissolve without clumps, which is good for mixing.
(2) Provide high bond strength.
9 extruded cement sheet
(1) It has high adhesion and lubricity and enhances the processability of extruded products.
(2) Improve green strength, promote hydration curing, and improve yield.
10 HPMC products for premixed mortar
HPMC products for ready-mixed mortar. The water retention in the ready-mixed mortar is superior to that of the ordinary product, ensuring that the inorganic cementing material is fully hydrated.The HPMC product for premixed mortar has a proper amount of venting, uniformity and small bubbles. The strength and smearing of the ready-mixed mortar can be improved.
Therefore, the HPMC product for premixed mortar has a certain retarding effect. It can extend the opening time of ready-mixed mortar and reduce the construction difficulty. Moreover, hydroxypropylmethylcellulose (HPMC) is made from natural polymer material cellulose.
