6 ,Sodium sulfite anhydrous used for making sodium sulfide , pulp , glass, water glass , enamel , also used as laxatives and barium salt poisoning antidotes . Is a byproduct of the manufacture of hydrochloric acid and sulfuric acid with salt when . For the manufacture of sodium sulfide , sodium silicate on the chemical . Laboratory for wash barium salt . Preparation for the industry to take NaOH and H ₂ SO ₄ raw materials , but also for paper, glass , printing and dyeing , synthetic fiber , leather and so on. Sodium in an organic synthesis laboratory of the most commonly used treatment desiccant.
7 Sodium sulfite anhydrous mainly used as synthetic detergent filler. Paper industry for cooking agent when manufacturing kraft pulp . Glass industry to replace soda . The chemical industry for the manufacture of sodium sulfide , sodium silicate raw materials and other chemical products . The textile industry for the deployment of Vinylon coagulating bath . The pharmaceutical industry as laxatives . Also used in non-ferrous metallurgy , leather and so on.
8 , so that the hydration products sulphoaluminate generate faster , thereby speeding up the rate of cement hydration and hardening . Sodium content of cement quality is generally 0.5 % to 2% , can improve the early strength of concrete by 50% to 100%, 28 days to improve the strength and sometimes , sometimes lower , increase rate of about 10% , with the type of cement , curing conditions its content varies . Also used as synthetic detergent filler , but also for the paper industry , glass industry, chemical industry, textile industry and pharmaceutical industry.
9 , Sodium sulfite anhydrous used as analytical reagents, such as dehydration, digestive catalyst fixed nitrogen , atomic absorption spectroscopy interference inhibitors. Also used in the pharmaceutical industry .
10 , for the chemical, paper and glass , dyes, printing and pharmaceutical industry, in the manufacture of synthetic fibers , leather , non-ferrous metallurgy , enamel , etc. There are also applications , also used as an additive in detergents and soaps .
11 , Sodium sulfite anhydrous can be used as a buffer to stabilize the sulfate zinc ph value of the bath .
