Guangzhou Hi Star Recycling Recycling tin line _ hi _ Hong Fu star tin recycling companies

Shenzhen Fu waste recycling Limited (www.szhongfu528.com) is located in Longgang District, Shenzhen Baolong Industrial Zone, Contact: Ouyang Qing tin recycling rates high Sn +6 OH-4e = Sn (OH) 6 reduction occurs at the cathode tin deposition reaction: Sn (OH) 6 +4 e = Sn +6 OH. Cathode tin produced is spongy. After pressing the sponge tin group, melting tin obtained about 98% of the crude tin. Tin total recovery of 95% to 98% recycled hi Guangxi Star line, tin removal rate of 99% and a current efficiency of 90% per ton of tin consumption 3000 ~ 4000kW · h, consumption of base 750 ~ 900kg. Research shows that electrolysis to produce a sponge tin divalent tin ions is due to the discharge caused by the organic oxidizing agent added can nitrobenzoic acid oxidized sn sn, can obtain a dense cathode tin. Accordingly, it is proposed oxidant mixing plus electrolysis. Mixing the electrolyte containing NaOH20 ~ 40g / L, p-nitrobenzoic acid 5 ~ 10g / L, Sn5 ~ 15g / L recovered Lucky-line, the temperature at 363 ~ 368K and a cathode current density of 400 ~ 500A / m density conditions cathode, tin recovery of 97.2%. ALPHA Lead-free no-clean solder paste, suitable for a variety of applications. ALPHA solder paste design allows a wide process window from there lead to problems related to lead-free transition to a minimum. The paste provides a considerable lead craft process performance. ALPHA solder paste on the board in different designs exhibited excellent printing capabilities, particularly those that require ultra-fine pitch (0.28mm2) and the need for consistent high production printing applications. Outstanding reflow process window so that it may well plates welded CuOSP Guangzhou Hi Star tin recycling line, and various sizes of printed dots are a good combination. It also has excellent anti-irregular beads and anti MCSB tin solder ball performance. ALPHA OM-338 solder joints look excellent, easy visual inspection. In addition, ALPHA OM-338 also reached voiding performance IPC CLASS ROL0 IPC Class III and grade levels to ensure long-term reliability of the product. Shenzhen Hong Fuxi recycling company specializing in recycling industry alpha solder paste, welcome to inquire.
