Boiler desulfurization caustic / soda / sodium hydroxide

Caustic soda, sodium hydroxide characteristics: 1. Water solubility: easily soluble in water, aqueous solution is colorless 2. The water absorption: a strong corrosive, water absorption and deliquescence (NaOH so open place, quality will increase), can be used as a desiccant, however, can not dry carbon dioxide and other acid gases, because it can react with CO2 and other so bad. Astringency and creamy liquid which is a colorless liquid,: (will react with the acidic gases.) 3. strongly alkaline. Sodium hydroxide reacts with carbon dioxide and deterioration in air. Caustic soda, sodium hydroxide security measures: sealed package, stored in a cool dry place. With acids, ammonium, easy (to) fuel storage points aliquot was shipped. Not in contact with the skin, if the skin (eye) contact with caustic rinse Hongyu contact with the flowing water: in Toshihide 13931721530 90 90 Industrial Caustic Caustic Caustic belong to non-national standard is mainly used for sewage treatment, boiler cleaning , brick desulfurization using caustic soda national standard is GB209-2006 industrial grade caustic soda 90 national standards for sewage treatment Caustic (GB209-2006) part of the standard on solid sodium hydroxide (including flaky, massive, granular) of : 99 caustic soda (IS-IT-Ⅰ) sodium hydroxide, sodium carbonate ≥ ≤ ≤ sodium ferric oxide ≤ superior products 99.0 0.5 0.03 0.005 0.008 0.05 First grade qualified products 98.5 98.0 0.8 1.0 0.08 0.01 96 caustic soda ( IS-DT-Ⅰ) sodium hydroxide, sodium carbonate ≥ ≤ ≤ sodium ferric oxide ≤ superior products 96.0 1.2 2.5 96.0 1.3 2.7 0.008 0.01 First grade qualified products 95.0 1.6 3.0 0.02 NOTE IS: solid sodium hydroxide IT: generally it refers to an ion-exchange membrane produced sodium hydroxide, but the process is not limited thereto.
