The greater the viscosity of cellulose ether is, the better the water retention property will be. The viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and apparatus to measure the viscosity of HPMC

Anti-dispersion is an important technical indicator to measure the quality of anti-dispersion agents. Hydroxypropyl Methylcellulose(HPMC) is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer, which can increase the viscosity of mixed water by increasing the consistency of the mixture. It is a hydrophilic polymer substance that can form a solution or dispersion after dissolving in water.

As a covering material for buildings, ceramic tiles are popular among people. In addition to providing decorative surfaces with aesthetic usage, ceramic tiles are also resistant to water, hard, hygienic and easy to clean. However, the problem of tile peeling,

The thermal insulation board supporting mortar is an important part of the external wall insulation, mainly the thermal insulation board adhesive and protective mortar. As a supporting material for the system, the components of the external insulation system must be regarded as a whole.

Applying RDP into mortar is actually the modification of ordinary mortar, also known as polymer modified cement mortar. Through polymer modification, the brittleness, high elastic modulus and other weaknesses of traditional cement mortar are improved;

The role of masonry mortar is to make block materials bonded into a whole. Generally the strength of block material is higher than that of mortar. The block materials in the mortar of low strength are usually in the state of flexural and shear stress. For the structural failure of masonry,

After dry-mixed mortar added with redispersible polymer powder is mixed with water, the modification of redispersible polymer powder on cement mortar is accomplished by redispersion of powder, hydration of cement and film formation of polymer.

HPMC are widely used in dry mix mortar products. The amount of cellulose ether, such as HPMC in dry mortar, added is very low, but it can significantly improve the performance of mortar and is an important additive that affects the construction performance of mortar. Cellulose ethers are rheology modifiers used to adjust the rheological properties of mortar.

Self-leveling mortar can rely on its weight to form a flat, smooth, and strong foundation on the substrate for laying or bonding other materials, and at the same time, it can carry out large-area and efficient construction. Therefore, high fluidity is a very significant feature of self-leveling mortar. Besides, it must have a certain degree of water retention and bonding strength, no segregation of water, and have the characteristics of insulation and low-temperature rise.
