What is Formaldehyde sodium bisulfite CAS 870-72-4？

Sodium methylate (PN for short) is a kind of high polymer, which needs to be used with SP, M, N, P, AESS, GISS, etc. It has a strong cathode polarization effect, can significantly enhance the brightness of the low area, the use of PN found that the brightness is insufficient, can appropriately increase the amount of high agent (polydisulfide). PN is the best high temperature carrier in copper acid brightener, suitable for complex workpiece plating.

Application

Sodium hydroxymethylsulfonate is used as an intermediate for isoniazid sodium sulfonate, neoarsvaramine, cancer, etc. It is also used as a fixative for protein fragrance, a floating lotion for lead-zinc ore and a color photo additive (anti-pollution and fading), cotton printing industry, and an important intermediate for the preparation of water treatment scale inhibitors. Scale inhibitors as a kind of water treatment agents are used in industrial production. Especially, it plays an important role in the treatment of NH2CH2 circulating cooling water and boiler cooling water. The research on the development agent of NHCH2 organic scale inhibitor containing phosphorus shows that the molecule contains carboxylic acid group, ester group, sulfonic acid group, phosphoric acid group and other specific functional groups, and has good effect on calcium carbonate (CaCO3), calcium sulfate (CaSO4), calcium phosphate and iron hydroxide in dispersed water, and has good water solubility.
