Hydroxyethyl cellulose (known as HEC) is a white or light yellow, odorless, non-toxic fibrous or powdered nonionic, manufactured through etherification of alkali cellulose and ethylene oxide (or chlorohydrin). HEC is soluble in both cold and hot water, and has no gel characteristics. It has a wide range of substitution, solubility and viscosity, good heat stability.. read more →

Cellulose Ether

Cellulose Ethers 0 Comment

Cellulose ether refers to cellulose derivatives on which hydroxyl groups are partially or completely substituted by ether groups. In dry mixed mortar products, the addition of cellulose can significantly improve the performance of mortar. Therefore it is an important additive in dry mixed mortar products. Cellulose ether can be divided into anionic type, cationic type.. read more →

Methylcellulose, a Cellulose Derivative with Original Physical Properties and Extended Applications 1. Introduction Chemically modified polymers have been extensively investigated in order to develop new biomaterials with innovating physic–chemical properties. Important classes of modified polymers are cellulose ethers, such as methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC) and carboxymethylcellulose (CMC). Cellulose is the most abundant polysaccharide.. read more →

⑴.Inorganic calcium sources like calcium carbonate, calcium phosphate and calcium oxide, or other machine processed animal bones, have high content of calcium, but need to be absorbed with involvement of gastric acid. So inorganic calcium is usually used for adult animals with fully developed digestive systems. (2). Organic calcium sources like calcium formate, calcium gluconate,.. read more →

basic concepts of cellulose ether In dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive that affects the performance of mortar construction. The cellulose ether is mainly made of natural fiber, and is processed by alkali dissolution, graft reaction(etherification),.. read more →

Acidifiers are mainly designed for weaned piglets as feed additive to compensate for lack of gastric acid in stomach. The research of acidifiers has a history of over 40 years. In 1960, people in feed industry found that piglet diarrhea can be relieved by organic acid. After that, simple acidifiers were used to lower pH.. read more →

Set-Accelerator refers to an additive, which can increase the mortar strength and has no significant effect on the later strength. According to the chemical composition, it is divided into two types: organic and inorganic.The organic includes Calcium Formate , Triethanolamine, Triisopropanolamine, Urea, etc. And the inorganic includes Sulfate, Chloride and so on. The effect of.. read more →
