Problems solved by technology

The main disadvantages of the traditional glass fiber electroless plating technology are: 1. Sodium hypophosphite is used as the reducing agent. Sodium hypophosphite has certain toxicity, and the sodium hypophosphite solution is easy to explode when heated and evaporated under normal pressure.
2. There is H in electroless plating 2 PO 2 － +H 2 O=H + +HPO 3 2- +H 2 As a side reaction, most of the added hypophosphite is finally converted into low-solubility phosphite. When there is a complexing agent and there are few free nickel ions, no precipitate will be produced; when there is nickel phosphite solid precipitate, the solution will be triggered. In electroless plating, there will inevitably be a small amount of nickel precipitated on the tank wall a
