Quantity: 30000 Specs:Specifications Payment Method: T/T,L/C,D/P Specifications 1 Na2S2O5 (96.5%min) 2 Best quatity & excellent service 3 Food and Tech grade 4 Annual production: 30, 000m Sodium Metabisulphite/Sodium Pyrosulfite Molecular weight: 190.10 Appearance: White or light yellow crystalline powder, relative Density is 1.4. Applications: Sodium metabisulfite's reductive and sulfonating properties provide versatile applications. It is used as an oxygen scavenger to eliminate the dissolved oxygen in waste water and in pipes. Bisulfite is a reductive bleaching agent. It reduces carbonyl and alcohol groups, which function as colorants of the substances. It is used in bleaching mechanical paper pulp, cotton, wool and kaolin clay. Additional applications include as a preservative (antioxidant), a hair waving agent, and Ensiling agent. Bisulfites are used in industries concerned with leather processing, food and beverage processing, gas purification, water treatment to remove excess chlorine, textiles and pulp processing, and many others. It is used as a reducing agent in chemical manufacturing. It is an alternative to sulfur dioxide which is used in sterlization of equipment.
