Water solubility and thickening: it can quickly dissolve in cold water, dissolve in some organic solvents and the mixed liquid of water and organic solvents; 3. Thickening and viscosity increasing: a small amount of increase […]
Read Moreconstruction hpmc-What raw materials are needed for the production of gypsum-based self-leveling mortar? Gypsum-based self-leveling mortar is mainly composed of base material, mixed material, admixture and other parts. The base material mainly refers to α-type hemihydrate gypsum made by autoclaving or hydrothermal synthesis, or β-type hemihydrate gypsum calcined with first-grade dihydrate gypsum with a purity […]

This method is suitable for measuring the dynamic viscosity of non-Newtonian fluids (polymer solution, suspension, emulsion dispersion liquid or surfactant solution, etc.). 2. Instruments and appliances 2.1 rotary viscometers (NDJ-1 and NDJ-4 are specified in the Chinese Pharmacopoeia) and viscometers with frequency stabilization measures (such as […]
Read MoreHPMC manufacturer-What Are the Main Functions of HPMC in A Dry Mix Mortar? Hydroxypropyl methylcellulose is one of the key ingredients in dry-mix mortars because of its ability to influence key dry-mix properties such as water retention, curing, workability, rheology, and thixotropy. 1. Water Retention The excellent water retention of hydroxypropyl methylcellulose gives the cement […]
Read MoreHPMC construction-How to test the viscosity of hydroxypropyl methylcellulose? Hydroxypropyl methyl cellulose for construction needs to avoid the infiltration of water into the wall, and the appropriate amount of water is retained in the mortar, which can make the cement fully produce good performance and perform the effect of water and water. Hydroxypropyl methyl cellulose […]
Read MoreHow To Dissolve HPMC(Hydroxypropyl Methylcellulose) Correctly? HPMC can be divided into instantaneous type (surface treatment) and hot melt type (non-surface treatment). The instant product disperses rapidly in cold water and disappears in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and not really dissolved. After about 2 […]
Read MoreHPMC 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 […]
