New production process of high substitution hydroxyethyl cellulose ether is explained

Hydroxyethyl cellulose is one of the cellulose ethers with a long history of use. At present, it is widely use in latex paint, oil field, cosmetics and other industrial production fields. With the economic development and social progress. People’s demand for yearly cellulose, the requirement of application performance is also more and more high. HEC

And the conventional hydroxyeyl cellulose in the market only in one aspect. Such as salt resistance, temperature resistance, enzyme resistance, good rheology or splash resistance, etc. And lacking in comprehensive performance, so the development of high performance new products is imminent.HEC

Hydroxyethyl cellulose is a kind of water-soluble cellulose ether produced worldwide, large yield, rapid development. Is an important cellulose ether varieties after CMC and HPMC, according to incomplete statistics. The world output in 1978 was 18,000 tons; 50,000 in 1983 tons, China only began production in 1977. HEC

Hydroxyethyl cellulose can dissolve in cold and hot water, giving it a wider range of soluble and viscosity properties. As a non-ionic ether, hydroxyeethyl cellulose has all the characteristics of non-ionic ether. Not with positive, negative charge ions, less activity, in a wide range of water-soluble polymer, surfactant. Salt coexistence, make it widely as thickening, flow regulator, protective glue, stabilizer, water retaining agent, binder, etc., used in latex paint, medicine, oil exploitation and other industries.HEC
