Environmental Protection Without Impurities White M series Refined Cotton

Short Description:

Refined cotton,cotton linters pulp as ether, ester products, known as industrial MSG in the world.
It is a fiber material made of linters by alkaline cooking. It can be used for industrial production of nitrocellulose, cellulose ether:CMC,MC,EC,HPC,CEC etc. and acetate. We adopting 100% Xinjiang cotton linters as raw material, alkaline cooking, oxidizing bleaching refined a uniform loose, no wood, bamboo shavings, sand, oil, metals and other impurities on the white floc. The main chemical ingredient is cellulose, lignin and hemicellulose. It is composed of carbon, hydrogen, three kinds of elements, the oxidizing bleaching subtracting refined cooking and refined cotton, has a low impurity content, the higher swelling capacity and response, preferably a polymerization degree and whiteness.

FEATURES

● All raw materials we adopt the Xinjiang and Central Asia cotton linters, the cotton linters has high maturity, refined cotton made by the cotton linters has high alpha cellulose content, etherification reaction to reduce polymerization degree in small amplitude.
● Because of the use of advanced and reasonable production technology, refined cotton whiteness could reach 87%, the polymerization degree can reach more than 2800, low content of impurities, without other fiber (no three wire.)

APPLICATION

Refined cotton M series for ether cellulose -1(1)

Refined cotton is the main material for manufacturing nitrocellulose (nitrocellulose) , widely used in food, medicine, daily chemical, plastics, electronics, paper making, metallurgy, aerospace and other fields, known as "special industrial monosodium glutamate".
