Product Description

 

      Sodium bisulfite formaldehyde is translucent white orthorhombic crystals or small pieces. Apparent density 1.80~1.85g/cm3. Easily soluble in water, slightly soluble in alcohol. It has extremely strong reducing properties under high temperature and can make the dyed color disappear, so it is called white lump. It decomposes when exposed to acid, and decomposes at 120°C to produce toxic gases such as formaldehyde and hydrogen sulfide. Anhydrous suspension white blocks are stable but will gradually decompose in humid air. Aqueous solutions begin to decompose above 60°C, and dilute solutions decompose much faster than concentrated solutions.

use
1. In the printing and dyeing industry, it is used as k-discharge agent and reducing agent to produce indigo dyes, vat dyes, etc. It is also used in synthetic rubber, sugar production and polymerization of vinyl compounds.
2. Used as a dye transfer agent for printing and dyeing, an activator for styrene-butadiene rubber and synthetic resin, a decolorizing and bleaching agent for organic matter, etc.
3. Mainly used in the printing and dyeing industry as a discharge agent, discharging agent, reducing agent and activator for styrene-butadiene rubber and synthetic resin. It is also used in the decolorization and bleaching of some organic substances (such as synthetic rubber, sugar, food industry As a bleaching agent), it can be used instead of insurance powder under certain conditions.
