SPECIFICATION

USE:
(1) Sewage treatment:
As a carbon source: In the biochemical treatment of sewage (such as anaerobic digestion, denitrification and phosphorus removal process), sodium acetate can provide energy and carbon elements for microorganisms, promote denitrification, and improve denitrification efficiency.
Adjust pH: Its aqueous solution is alkaline and can be used to neutralize acidic wastewater and stabilize the pH environment of the treatment system.
(2) Textile printing and dyeing:
As a buffer, it regulates the pH of the dye bath to ensure a uniform and stable dyeing process, reducing dye waste and color aberration.
Mordant used in cotton fabrics to enhance the adhesion between dyes and fibers and improve dyefastness.
(3) Leather processing:
As a tanning aid, it helps to soften the leather and at the same time regulates the acidity during the tanning process and improves the quality of the leather.
(4) Synthetic materials:
further synthesis of coatings, adhesives, textiles, etc.
It is used as an additive in polyurethane, rubber and other industries to improve material properties.
