Refined 99.2% Soda Ash Dense Chemical name: sodium carbonate Molecular Formula: Na2CO3 Appearance: white crystalline powder Chemical name: sodium carbonateMolecular Formula: Na2CO3Appearance: white crystalline powderProperties: soluble in water, alkaline aqueous solution significantly, and release heat, easy to deliquescence; react with the acid salt generated.Uses: soda is the most important one of chemical raw materials widely used in chemical, glass, metallurgy, paper making, printing and dyeing, synthetic detergent, petrochemical, food, medicine and health industry, the amount of large, important in the national economy status.Specification: Light Soda Ash (sodium carbonate industry, consumption of soda ash), Dense SodaThe implementation of quality standards:Industrial soda ash (light soda ash, heavy soda ash) the implementation of People's Republic of China issued the "Industrial sodium carbonate GB210-1992" standards, both product quality reach the international advanced level. Soda consumption of the implementation of People's Republic of China issued a "food additive sodium carbonate GB1886-1992" standard.Technical indicators for the quality of soda ash consumption: GB1886 - 1992Index nameClass indicatorsExcellentFirst-class goodsFirst-class goodsAlkaloids volume (dry basis of the mass fraction of Na2CO3)% ≥99.298.898.0NaCl % ≤0.700.901.20Iron (Fe) the mass fraction (dry basis)% ≤0.00350.0060.010Sulfate (SO4 dry basis of the mass fraction of the total)%0.03The quality of water insoluble matter% ≤ Score0.030.100.15LOI 2),% ≤0.81.01.3Bulk Density (g / ml) ≥0.900.900.90Particle size, 180μm sieve residue% ≥70.065.060.0Technical indicators for the quality of soda ash consumption: GB1886 - 1992ItemIndicatorsAlkaloids volume (dry basis Na 2 CO 3 of the mass fraction of total)% ≥99.2Sodium chloride (dry basis of the mass fraction of NaCl)% ≤0.7Iron (Fe) the mass fraction (dry basis)% ≤0.004Heavy metals (Pb) content,% ≤0.001Arsenic (as of) content,% ≤0.0002Loss on ignition 1),% ≤0.8Water Insoluble% ≤0.03Technical indicators for the quality of soda ash consumption: GB1886 - 1992Light soda ash (kg / bag)Dense Soda (kg / bag)Remarks25The use of composite woven bags, flexible container bags or bulk packaging40507501000BulkBulk
