With the rapid development of the construction industry, people have increasing demands for new building materials. Due to the increase in people’s awareness of environmental protection and the continuous improvement of construction efficiency,

The water putty is divided into two kinds: dry powder putty and putty paste. In the two kinds of putty, the modified methyl cellulose and hydroxypropyl methyl cellulose are generally chosen for use, and the viscosity is the most suitable between 30000-60000cps.

In the dry-mixed mortar, the cellulose ether plays a role in such aspects as water retention, thickening and improving construction performance. Good water retention can avoid the sugaring, dusting and strength decrease of mortar resulting from water shortage and incomplete cement hydration;

Cellulose ethers are currently the commonly used polymer admixtures of the cement mortar used in construction. Cellulose ethers can be fully dispersed in water to form a transparent viscous liquid. With a small amount (the mass percentage of less than 1%) added to the cement,

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;
