Application
It is mainly used as a discharging agent, color-discharging agent, reductant in printing and dyeing industry, as an activating agent for production styrene-butadise rubber and synthetic resin, also be used to decolourize and bleach some organic matters, for example: as a bleaching agent in synthetic rubber, sugar-making, and food industries. It may be substituted for the sodium hydrosulfite in some special conditions.
Should be stored in a dry, cool and dark place. Protected from moisture, avoided exposure to direct sunshine. Don’t to let it be rained on. Be sure not to store it together with oxidant and acid, no presence of acidic vapour in storage life is one year.
In the printing and dyeing industry, it is used as a discharge agent and vat dye for cotton, rayon, short fiber fabrics, etc. Used as a redox catalyst when preparing synthetic resins and synthetic rubbers. It is also used as an antidote, sugar bleaching agent, detergent, detergent, and for the preparation of indigo dyes, vat dyes, etc. Sodium formaldehyde sulfoxylate is one of the most commonly used reducing agents in discharge printing, which can make the dyed color disappear, so it is named as white powder. Hanging white block is mainly used in rubber industry styrene-butadiene rubber polymerization activator, printing and dyeing process bleaching agent, photosensitive photographic material auxiliary agent, daily industrial bleaching agent and pharmaceutical industry, etc., appearance: white block
