Summary of application pain points of gypsum mortar retarder 1. Retarder gypsum has poor adaptability: It has a good retarding effect on some gypsum, but a poor retarding effect on some gypsum. If the dosage is increased several times, the retarding effect on different batches of gypsum will vary greatly. 2. Dosage of retarder is
NDJ viscosity and Brookfield viscosity are two common viscosity measurement methods. Viscosity is a measure of a liquid's resistance to flow and is used to describe how thick a liquid is. In industrial production and scientific research, viscosity is an important parameter, which has an important influence on the rheological properties and processing performance of
The plastering mortar on the wall has low strength, insufficient marking, sand and powder loss, hollowing and cracking, and unevenness... Many people will find it very troublesome if the above situations occur! However, if these phenomena are just superficial, they may not be as serious as you think. As long as there is nothing wrong

Different effects of HPMC, starch ether and RDP on gypsum mortar Hydroxypropyl methylcellulose (HPMC) 1. It is stable to acids and alkalis, and its aqueous solution is very stable in the range of pH=2~12. Caustic soda and lime water do not have much impact on its performance. But alkali can speed up its dissolution. And
Synthesis principle of hydroxyethyl cellulose When the molar substitution degree (MS) of hydroxyethylcellulose is 0.05-0.5. It is an alkali-soluble product. HEC with an MS above 1.3 is soluble in water. The MS range of common industrial HEC products currently on the market is 1.3 to 2.5. And the DS range of most water-soluble HEC products
HPMC is used in chemical industry and other industries Chemical industry 1. Polymerization of vinyl chloride and vinylidene: As a suspension stabilizer and dispersant during polymerization. It can be used together with vinyl alcohol (PVA) and hydroxypropyl cellulose (HPC) to control the particle shape and particle distribution. 2. Adhesive: As an adhesive for wallpaper, it
HPMC is used in construction and cosmetics industry Construction industry 1. Cement mortar: Improve the dispersion of cement-sand and greatly improve the plasticity and water retention of mortar. It is effective in preventing cracks and can enhance the strength of cement. 2. Tile cement: Improve the plasticity and water retention of pressed tile mortar, improve
This article introduces HPMC for food and pharmaceutical Food Industry 1. Canned citrus: Prevents the whitening and deterioration caused by the decomposition of citrus glycosides during storage to achieve the preservation effect. 2. Cold fruit products: added to sherbet, etc. to make the taste better. 3. Sauce: used as an emulsifying stabilizer or thickener for
