Superiority

99% high purity 870-72-4 reliable manufacturers 870-72-4 Formaldehyde Sodium Bisulfite

1. Sodium hydroxymethyl sulfonate (PN) is a polymer, which needs to be used in combination with SP, M, N, P, AESS, GISS, etc.

2.It has a very strong cathodic polarization, can significantly enhance the brightness of low areas, the use of PN found insufficient brightness, can appropriately increase the amount of high agent (polydisulide).  
 
3. PN is the best high temperature carrier of sour copper lumens, suitable for electroplating complex workpieces.  

4. It can be used in the range of 15 degrees C to 45 degrees C, PN is not only suitable for acid copper, but also can be used for cyanide-free galvanizing brighteners.

5. Nickel-plated heavy metal complex agent.

6. Widely used, sodium hydroxymethyl sulfonate can effectively complex copper, zinc, lead and other metal ions. Lead-zinc ore floating lotions and color photo aids (anti-pollution and fading), cotton printing industry.

7. Does not contain SO32-, with de-hybrid, walk, soft function.

Production method

The distilled water and formaldehyde solution will be added to the reaction pot, cooled to less than 15 degrees C, stirred under the batch added sodium sulphate, control temperature at 60-65 degrees C reaction 20min, with sodium hydroxide solution to control pH9 or so. After the reaction, add hydrochloric acid to make pH up to about 3. Add activated carbon decolorization, filtration, filter cooling after adding ethanol to extract solids, placement, next day filtration, ethanol washing, drying, finished products.
