Quantity: 5000Metric Tons Specs: acetate Price:1990 USD Metric Tons 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 Our company refined cotton product features: 1. 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. 2 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.)C series refined cotton standard specification for ACETATE GRADE Types C100 C200 Viscosity mPa.s 71～120 121～300 Degree of polymerization 1301～1600 1601～1900 Alpha-cellulose % >= 99.0 99.0 Moisture % <= 8.0 8.0 Water absorptivity g/15g 160 160 Ash content % <= 0.10 0.10 Sulphuric acid insoluble % <= 0.10 0.10 Brightness % >= 87 87 Iron content mg/kg <= 15 15 Ether content % <= 0.15 0.15 Soda soluble 7.14% <= 2.0 2.0 Copper content <= 0.20 0.20 |
