Pharmaceutical Sustained-release Excipients

Pharmaceutical Sustained-release Excipients 01 Cellulose ether   Cellulose can be divided into single ethers and mixed ethers according to the type of substituents. There is only one type of substituent in a single ether, such as methyl cellulose (MC), ethyl cellulose (EC), hydroxyl Propyl c... Read More

Cellulose ether uses in dry mixed mortar

Cellulose ether uses in dry mixed mortar The effects of several common cellulose single ethers and mixed ethers in dry-mixed mortar on the water retention and thickening, fluidity, workability, air-entraining effect, and strength of dry-mixed mortar are reviewed. It is better than a single ether;... Read More

How Many Additives in dry mix mortar?

1. Water retention and thickening material The main type of water-retaining thickening material is cellulose ether. Cellulose ether is a high-efficiency admixture that can greatly improve the specific performance of mortar with only a small amount of addition. It is converted from water-insoluble... Read More

What is gypsum-based self-leveling mortar?

Gypsum-based self-leveling is a new type of ground leveling material that is green, environmentally friendly and high-tech. By utilizing the good flowability of gypsum-based self-leveling mortar, a large area of finely leveled ground can be formed in a short time. It has the advantages of high fl... Read More

Cosmetic thickeners and stabilizers

01 Thickener thickener：After being dissolved or dispersed in water, it can increase the viscosity of the liquid and maintain a relatively stable hydrophilic polymer compound in the system. The molecular structure contains many hydrophilic groups, such as -0H, -NH2, -C00H, -COO, etc., which can h... Read More

Effect of cellulose ether on plastic free shrinkage of mortar

Effect of cellulose ether on plastic free shrinkage of mortar A non-contact laser displacement sensor was used to continuously test the plastic free shrinkage of HPMC modified cement mortar under accelerated conditions, and its water loss rate was observed at the same time. HPMC content and plast... Read More

Cellulose ether modified cement slurry

Cellulose ether modified cement slurry   The effect of different molecular structure of non-ionic cellulose ether on the pore structure of cement slurry was studied by performance density test and macroscopic and microscopic pore structure observation. The results show that nonionic cellulos... Read More

Pharmaceutical Excipients Cellulose Ether

Pharmaceutical Excipients Cellulose Ether Natural cellulose ether is a general term for a series of cellulose derivatives produced by the reaction of alkali cellulose and etherifying agent under certain conditions. It is a product in which the hydroxyl groups on cellulose macromolecules are parti... Read More

Downstream Industry of Cellulose Ether

Downstream Industry of Cellulose Ether As “industrial monosodium glutamate”, cellulose ether has a low proportion of cellulose ether and has a wide range of applications. The downstream industries are scattered in all walks of life in the national economy. Normally, the downstream con... Read More

Cellulose ether on the slag sand mortar

Cellulose ether on the slag sand mortar Using P·II 52.5 grade cement as the cementitious material and steel slag sand as fine aggregate, the steel slag sand with high fluidity and high strength is prepared by adding chemical additives such as water reducer, latex powder and defoamer Special morta...

How does the fineness of cellulose ether affect the performance of mortar?

Both carboxymethyl cellulose and methyl cellulose can be used as water-retaining agents for plaster, but the water-retaining effect of carboxymethyl cellulose is far lower than that of methyl cellulose, and carboxymethyl cellulose contains sodium salt, so it is not suitable for plaster of paris. ...
