| HPMC has a wide range of roles in construction materials, it can be applied to masonry mortar, plastering mortar, stucco, plastering paste, adding a small amount of HPMC to the material will result in a great improvement in these properties. In cement and gypsum based, plasters, the moisture retention effect of HPMC will result in high bond strength and hardness of the plaster after curing.
High water retention can make the cement fully hydrated, significantly increase the bond strength, but also appropriate to improve the tensile bond strength and shear bond strength of hardened mortar, but also significantly improve the ease of use and lubricity, greatly improve the construction effect, improve work efficiency. When cement mortar is used, it is important to ensure good water retention because of the strong water absorption of bricks and wall surfaces, coupled with the high sand content of the mortar. Otherwise, bricks etc. can easily adsorb the water out of the mortar, making the mortar partially water-loss and the cement difficult to fully hydrate. The bond strength of mortar composed of sand-lime-cement is very low, and after adding cellulose ether, the bond strength increases significantly, and the tensile bond strength and shear bond strength will be relatively high even if there is a significant eccentric load or horizontal load occurs.

Suitable for water-resistant putty
In water-resistant putty, the main role of cellulose ether is to retain water,
improve adhesion as well as lubricity, to avoid cracks or powder phenomenon caused by rapid loss of water, and at the same time to enhance the adhesion of the putty to reduce the phenomenon of hanging in the construction, so that the construction of the smoother, less labor, and enhance the controllability. |
Suitable for plastering
In gypsum series products, cellulose ether mainly plays the role of water retention, thickening, lubrication, etc. It also has a certain retardation effect, which can solve the problems of bulging and cracking in the process of construction, and the problem that the initial strength cannot be reached, and prolong the working time.
|
Suitable for slurry sprayingSpray slurry with cellulose is suitable for all kinds of protective works on internal and external walls of buildings, roofs, floors and tunnels. Cellulose can form a certain combing effect in the spray slurry material, increasing the cohesion and adhesion of the material, thus effectively overcoming the cracking problem of the material itself, and improving the impermeability and durability of the sprayed layer. |
Suitable for daily-use chemicals
Commonly used in cosmetics, shampoos, shower gels and other daily-use chemicals.HPMC has good thickening properties and can be thickened by combining with water molecules to form a colloid.HPMC can increase the consistency of the product, making it easier to apply and use. It has excellent moisturizing properties and can absorb and retain water molecules.
|
Suitable for caulking
The addition of HPMC provides good edge bonding, low shrinkage and high abrasion resistance, protecting the base material from mechanical damage and avoiding the negative effects of water penetration on the building.
|
Suitable for self-leveling cement mortar |
