Caustic Soda is raw material in the manufacturing of soaps, detergents,textiles and paper. Also in water softening and treatment.
2. Materialization nature: The pure product is the colourless transparent crystal, relative density. The main body is white,having luster and absorbing moisture easily,presenting alkalinity. It has strong corrosiveness and rises neutralization reaction with acid, and it can absorb NaCl,Na2SO4 etc. It also can rise reaction with organic matters, inorganic matters. The purely solid caustic soda is , there are bulk , granular, the quality is fragile ; The purely liquid caustic soda is the colourless transparent liquid. Dissolve caustic soda in water, it will send out heat and the aqueous solution is alkaline. Corrosivity is extremely strong, have function of corroding on fibre , skin , glass , pottery ,etc..
3. Usage: Caustic soda products widely used, is the most basic chemical raw materials; widely used in chemical industry, metallurgy, paper, petroleum, textile and chemical sectors .
(1) manufacturing soap. The main components of soap, the sodium salt of higher fatty acids, usually oil and caustic soda, caustic soda, sodium hydroxide as raw materials made through the saponification reaction.
(2) of refined petroleum. By the sulfuric acid washing of petroleum products also contain a number of acidic substances, must use caustic soda, caustic soda, sodium hydroxide solution, washed, and then by washing in order to obtain refined products.
(3) paper. Paper-making raw materials are wood or grass-like plants, except where these plants contain cellulose, but also contains a considerable number of non-cellulose (lignin, gums, etc.). Add dilute caustic soda, caustic soda, sodium hydroxide solution can be dissolved in the separation of non-cellulose components, thus the system can be mainly composed of cellulose pulp.
(4) textiles. Man-made fibers such as rayon, fake fur, artificial silk, etc., mostly viscose fibers, which is cellulose (such as the pulp), caustic soda, sodium hydroxide, carbon disulfide (CS2) as the raw material made of viscose liquid, by spraying silk, condensation and obtained.
(5) printing and dyeing. Cotton with caustic soda, caustic soda solution after treatment can remove the covering the cotton on the wax, grease, starch and other substances at the same time can increase the mercerized fabric color, so that more uniform dyeing.
