What are the benefits of using hydroxypropyl methylcellulose as a hollow capsule?
This product is 2-hydroxypropyl ether methyl cellulose, which is a semi-synthetic product. It can be produced by two methods: (1) After treating cotton linters or wood pulp fibers with caustic soda, they are mixed with chloromethane and epoxy Propane reacts, refined and pulverized to get it; (2) ...Read more -
Which plant-derived materials are suitable for the production of hollow hard capsules?
In the century-old history of capsules, gelatin has always maintained its position as the mainstream capsule material due to its wide range of sources, stable physical and chemical properties, and excellent processing performance. With the increase of people’s preference for capsules, hollo...Read more -
How is Hypromellose (HPMC) used in extended-release matrix tablets?
In the pharmaceutical industry, hypromellose (HPMC, METHOCEL?) can be used as filler, binder, tablet coating polymer and key excipient to control drug release. Hypromellose has been used in tablets for more than 60 years and is a key excipient widely used in hydrophilic gel matrix tablets. Many p...Read more -
What is the application of hydroxypropyl methylcellulose ether in machine blasting mortar?
The mechanized construction of mortar has been tried and promoted for many years in China, but no substantial progress has been made. In addition to people’s skepticism about the subversive changes that mechanized construction will bring to traditional construction methods, the main reason ...Read more -
What effect does cellulose ether have on cement-based materials?
1. Heat of hydration According to the release curve of the heat of hydration over time, the hydration process of cement is usually divided into five stages, namely, the initial hydration period (0~15min), the induction period (15min~4h), the acceleration and setting period (4h~8h ), deceleration ...Read more -
How about hydroxypropyl methylcellulose 400 viscosity as self-leveling mortar?
Self-leveling mortar is a dry-mixed powder material composed of a variety of active ingredients, which can be used after mixing with water on site. After a little spreading with a scraper, a high flat base surface can be obtained. The hardening speed is fast, and you can walk on it within 24 hour...Read more -
Do you understand the important role of cellulose ether in ready-mixed 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 -
What factors affect the thickening of cellulose ether?
The thickening effect of cellulose ether depends on: the degree of polymerization of cellulose ether, solution concentration, shear rate, temperature and other conditions. The gelling property of the solution is unique to alkyl cellulose and its modified derivatives. The gelation properties are r...Read more -
How effective is hydroxyethyl cellulose as a thickener?
Cellulose is a polysaccharide that forms a variety of water-soluble ethers. Cellulose thickeners are nonionic water-soluble polymers. Its use history is very long, more than 30 years, and there are many varieties. They are still used in almost all latex paints and are the mainstream of thickeners...Read more -
What is the effect of hydroxypropyl methylcellulose on cement mortar?
Hydroxypropyl methylcellulose can improve the dispersion resistance of cement mortar. Hydroxypropyl methylcellulose is a water-soluble polymer compound. It generally increases the consistency of the mixture by increasing the viscosity of the mixing water. It can be dissolved in water to form a vi...Read more -
