HPMC manufacturer-The influence of the smell of hydroxypropyl methylcellulose on the quality The synthesis of hydroxypropyl methylcellulose: the refined cotton cellulose is treated with lye at 35-40℃ for half an hour, squeezed, the cellulose is crushed, and properly aged at 35℃, so that the obtained alkali fiber has an average degree of polymerization Within the […]
Read MoreHPMC manufacturer-The role of hydroxypropyl methylcellulose in dry-mixed ready-mixed mortar In the process of dry-mixed ready-mixed mortar, the addition amount of hydroxypropyl methylcellulose is relatively low. Although the addition amount is low, which is also a major additive that affects the construction performance of mortar. Therefore, a scientific and reasonable choice of cellulose ethers of […]
Read MoreHPMC – Hydroxypropyl methyl cellulose HPMC Hydroxypropyl MethylCellulose has thermal gelation properties, so after heating the aqueous solution will precipitate and form gels, and dissolve again after cooling. Products of different specifications have different gelling temperatures. Its solubility varies with the viscosity, and the lower the viscosity is, the greater the solubility will be. There are some […]
Read MoreHPMC manufacturer-Factors affecting the water retention of hydroxypropyl methylcellulose The greater the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to determine the viscosity of HPMC. The main methods are Haake Rotovisko, Hoppler, Ubbelohde and […]
Read MoreHydroxypropyl methylcellulose has its unique properties in the application of building materials, from mixing to dispersion to construction, as follows: Compounding and configuration 1. It is easy to mix with dry powder formula. 2. It has the characteristics of cold water dispersion. 3. Effectively suspend solid particles and make the mixture more smooth and uniform. […]
Read MoreHPMC manufacturer-The thickening effect of hydroxypropyl methylcellulose in putty powder mortar The viscosity of the hydroxypropyl methylcellulose solution depends on the following factors: 1. The molecular weight and concentration of cellulose ether, solution temperature, shear rate and test method. 2. The higher the degree of polymerization of cellulose ether, the higher the molecular weight and […]
Read MoreHPMC manufacturer-Main applications of Hydroxypropyl Methylcellulose (HPMC) 1. Tile Adhesive Since the tile adhesives must have very high bonding strength between the base layer and ceramic tiles, so adhesives are affected by two aspects of absorbed water, the surface of base layer (the wall/floor) and ceramic tiles. For ceramic tiles, there are large differences in […]
