Recently returned home and abroad to use the tin bath are more complicated, expensive, and some pollution is serious, there seems to be inefficient, and some back-plated too slow, this retreat is designed to help recycling companies bath or recovery of tin plating electroplating back with, simple and easy to get their raw materials, short production cycle, it has high economic benefits. And Surface Treatment Materials Co., Ltd. by Bonthe laboratory proved its feasibility should be for everyone to promote.

 

Boric acid: 8%

Hydrofluoric acid: 50%

Nitric acid: 10%

Water: 32%


Room temperature can be plated back

Prepared as follows: If equipped with 100 kg stripper

First prepared 32KG water, heating to 60-70 degrees, then add 8 kg of boric acid, cooling and then adding hydrofluoric acid: 50 kg; nitrate 10 kg.

 

 

Remember: 1, time should be used with hard plastic barrel.

      2, start ratio, there were irritating taste, should pay attention to protection.

      3, if they think too fast, then add some water

BT-off powder (also known as stripping payment agent, peeling powder, retired powder) is used to back-plated gold plated gold layer and the recovery of an effect of the chemical. Does not corrode the substrate coating and the substrate (such as copper, nickel, tin); back gold fast, thorough, generally 20 seconds or so can be off the net. 1KG off powder can be recycled to the 300g-500g of gold. Gold recovery of 99%, BT-off powder by repeated crystallization to remove nitrate ions, to avoid the recovery of gold and adjust PH value when the hydrochloric acid formed a "aqua regia" sponge dissolved gold, pure gold can be recovered up to 24K. Compared with the traditional recycling process, the use of this product is simple, need little space. Powder does not contain toxic materials removal, storage, transportation is very safe.
