hpmc manufacturer-Daily chemical grade hpmc hydroxypropyl methylcellulose 1. Natural raw materials, low irritation, mild performance, safety and environmental protection; 2. 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 Morehpmc manufacturer-Cellulose Ether Classification Hydroxyethyl Cellulose and Hydroxypropyl Methyl Cellulose Cellulose ethers are classified according to the different etherification agents used. Hydroxypropyl methyl cellulose, methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, benzyl cyanoethyl cellulose cellulose, carboxymethyl hydroxyethyl cellulose, etc. Hydroxypropyl methylcellulose and hydroxyethyl cellulose are more practical. The solubility of cellulose after etherification has […]
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-Temperature of hydroxypropyl methyl cellulose gel Many users rarely pay attention to the problem of hydroxypropyl methyl cellulose gel temperature. Now, viscosity is generally used to distinguish hydroxypropyl methyl cellulose, but for some special environments and special industries, the viscosity of products is not enough. Here is a brief introduction of hydroxypropyl methyl cellulose […]
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 Morerdp powder-Redispersible Polymer Powder has a Good Improvement Effect on Tile Adhesives Redispersible polymer powders are spray-dried emulsions that, when mixed with water or water in a mortar, form the same stable dispersion as the original emulsion. The characteristic of redispersible polymer powder is that this powder can only be dispersed once, and it will not […]
Read Moreredispersible powder-Redispersible latex powder for tile adhesive grouts free sample Re-dispersible polymer powder, produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAC/E), then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles. The film acts as […]
Read Morevae redispersible powder-Test of viscosity of redispersible latex powder At present, the widely used redispersible latex powder in the world occupies a dominant position in the entire market, has a priority in the global field, and represents the technical characteristics of the redispersible latex powder. From the technical experience of polymers applied in mortar modification, […]
