HPMC use and application
The main purpose 1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic...Read more -
Quality Identification of Hydroxypropyl Methyl Cellulose
one. The difference between adulterated hydroxypropyl methylcellulose (HPMC) and pure hydroxypropyl methylcellulose (HPMC) 1. Appearance: Pure hydroxypropyl methylcellulose HPMC looks fluffy and has a low bulk density, ranging from 0.3-0.4g/ml; adulterated hydroxypropyl methylcellulose HPMC has b...Read more -
Application of Carboxymethyl Cellulose in Food Industry
Carboxymethylcellulose (CMC) is synthesized from fibers (fly/short lint, pulp, etc.), sodium hydroxide, and monochloroacetic acid. According to different uses, CMC has three specifications: pure product purity ≥ 97%, industrial product purity 70-80%, crude product purity 50-60%. CMC has excellent...Read more -
Functional Properties of CMC (Carboxymethyl Cellulose)
Carboxymethyl cellulose (sodium carboxyme thyl cellulose, CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, and is the most important ionic cellulose gum. CMC is usually an anionic polymer compound prepared by reacting natural cellulose with caustic alkali and mono...Read more -
Preparation of carboxymethyl cellulose
Carboxymethyl Cellulose (English: Carboxymethyl Cellulose, CMC for short) is a commonly used food additive, and its sodium salt (sodium carboxymethyl cellulose) is often used as a thickener and paste. Carboxymethyl cellulose is called industrial monosodium glutamate, which is widely used in indus...Read more -
Dissolution and Dispersion of Carboxymethyl Cellulose
The quality of carboxymethyl cellulose CMC mainly depends on the solution of the product. If the product solution is clear, there are less gel particles, less free fibers, and less black spots of impurities. Basically, it can be determined that the quality of carboxymethyl cellulose is very good....Read more -
What is the most suitable viscosity of hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose is generally used in putty powder with a viscosity of 100,000, while mortar has a relatively high viscosity requirement, so it should be used with a viscosity of 150,000. The most important function of hydroxypropyl methylcellulose is water retention, followed by thi...Read more -
The role of cellulose in mortar
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more -
The role of cellulose in self-leveling mortar
Cellulose ether is a general term for a series of products produced by the reaction of alkali cellulose and etherifying agent under certain conditions. Alkali cellulose is replaced by different etherifying agents to obtain different cellulose ethers. According to the ionization properties of subs...Read more -
Hydroxypropyl Methyl Cellulose (With Recipe)
Hydroxypropyl methylcellulose (HPMC for short) is an important mixed ether, which is a non-ionic water-soluble polymer, and is widely used in food, medicine, daily chemical industry, coating, polymerization reaction and construction as a dispersion suspension , thickening, emulsifying, stabilizin...Read more -
Application of methyl cellulose in food
Cellulose is the most abundant natural polymer in nature. It is a linear polymer compound connected by D-glucose through β-(1-4) glycosidic bonds. The degree of polymerization of cellulose can reach 18,000, and the molecular weight can reach several million. Cellulose can be produced from wood pu...Read more -
Talking about the types and characteristics of thickeners
Thickener is a special kind of rheological additive, its main function is to increase the viscosity of paint liquid, improve the storage performance, construction performance and paint film effect of paint. The role of thickeners in coatings thicken Anti-settling Waterproof Anti-sagging Anti shri...Read more
