Printing and dyeing, textile industry, but also with plenty of lye to remove the cotton and wool grease top. Rayon production also requires caustic soda or soda ash. For example, the first to use the system of viscose fibers 18 to 20% caustic soda solution (or soda ash solution) to the impregnated cellulose, making it an alkali cellulose, the alkali cellulose is then dried, pulverized, and finally with dilute lye together with the sulfonamide salt dissolve, then get viscose. Then filtered, vacuum (to the bubble) caustic soda supply, can be used to snag the. Refined petroleum but also with caustic soda. To remove gum petroleum fractions, the general increase in petroleum distillates of concentrated sulfuric acid to make the gum to become acid residue and precipitation. After pickling uses caustic soda, oil also contains phenol, naphthenic acid and other acidic impurities and excess sulfuric acid must be washed with a caustic soda solution, then washed, in order to obtain refined petroleum products. Our responsibility to our customers believe that customers' success is our success! We are the best customers trusted partner. Soda role in the field of chemistry experiment chemistry experiment reagent used in addition to outside, because it has a strong water absorption and deliquescence, can also be used to make alkaline desiccant. Sodium hydroxide is widely applied in industry in the national economy, many industrial sectors need sodium hydroxide. Sodium hydroxide is the most used chemicals manufacturing sector, followed by paper, aluminum, tungsten refining, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of the old rubber, made of metal sodium, water electrolysis as well as inorganic salt production, preparation of borax, chromium salts, manganese, phosphate, etc., should use a lot of soda. Main uses: chemical manufacturing, paper, aluminum, tungsten refining, rayon, rayon and soap manufacturing, production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration system of metallic sodium, water electrolysis and inorganic salt production, manufacture of caustic soda manufacturers of borax, chromium salts, manganese, phosphate, etc. should use a lot of soda because we are professionals so we do a better quality of the first faith-based quality assurance caustic soda production at reasonable prices Manufacturers _ Zhengzhou Longda Chemical (certified) _ caustic soda provided by Zhengzhou Longda Chemical Products Co., Zhengzhou Longda Chemical Products Co., Ltd.
