1. Application in Silicate Industry In ceramic industry, Sodium Carboxymethylcellulose can be used as the rough adhesive agent, plasticizer, glaze suspending agent and dye-fixing agent. Sodium Carboxymethylcellulose can also be used in construction works. For example, in concrete construction, adding Sodium Carboxymethylcellulose can reduce water loss and has…
Preparation of hydroxyethyl cellulose 1. Overview Alkali cellulose is a natural polymer. Each of the fiber-based rings contains three hydroxyl groups, and the most reactive hydroxyl groups react to form hydroxyethyl cellulose. The raw cotton linters or refine mash are soaked in 30% liquid alkali,…
The specific role of building grade hydroxypropyl methyl cellulose ether (HPMC) 1. Construction mortar plastering mortar High water retention can make the cement fully hydrated, significantly increase the bond strength. And at the same time increase the tensile strength and shear strength, greatly improve the…
The nature of hydroxyethyl cellulose I. Overview Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdery solid. That is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin). It is a non-ionic soluble cellulose ether. It has…
What is the main use of carboxymethyl cellulose(CMC）? Carboxymethylcellulose is a carboxymethyl group substituted product of cellulose. Depending on its molecular weight or degree of substitution, it may be a fully dissolved or insoluble polymer. The latter can be used as a weak acid type…
Hydroxypropyl Methyl Cellulose HPMC 1.The main use of cellulose ether HPMC? HPMC is widely used in construction mortar, waterborne coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, cosmetics, tobacco, and other industries, and is divided into building grade, food grade, and pharmaceutical grade. PVC industrial grade…
Hydroxypropyl Methyl Cellulose(HPMC) problems 1. What are the main technical indicators of HPMC? The hydroxypropyl content and viscosity, which most users care about are these two indicators. If the hydroxypropyl content is high, the water retention is generally better. 2. What is the viscosity of…
Hydroxyethyl cellulose (HEC) Hydroxyethyl cellulose (HEC) It is a white or light yellow, odorless, non-toxic fibrous or powdery solid. It is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin), and is a nonionic soluble cellulose ether. Because HEC has good properties…
Comparative Advantage Analysis of Gelatin and HPMC Capsules HPMC has good properties of film formation, dispersion,water retention and protection of colloids. And it is widely used in medicine and food. What is the effect of HPMC hollow capsules on disintegration and dissolution? 1.Chemical structure Gelatin…
Hydroxypropyl methylcellulose ten questions 1. Hydroxypropyl methylcellulose is a nonionic cellulose ether. So what is nonionic? Generally speaking, non-ion is a substance that does not ionize in water. Ionization refers to the process by which an electrolyte is dissociate into a freely moving charged ion…
