Papa PCB uila pinch gula a me ka nickel poho gula ʻokoʻa?

Loaʻa ka gula PCB papa ma o ka electrolysis, a loaʻa ke gula ma o ka hopena hoʻoliʻiliʻi kemikala.

He aha ka ʻokoʻa ma waena o ke gula uila PCB a me ke gula niki i piholo.

E waiho wale ia, PCB electroplating gula, e like me nā PCB electroplating, pono uila a me ka rectifier. Nui a hewahewa nā ʻano o ke kaʻina hana, e laʻa me ka cyanide, ʻōnaehana cyanide ʻole, ʻōnaehana non-cyanide a me ka waikawa citric, sulfite a pēlā aku. Hoʻohana ʻia i ka ʻoihana PCB he ʻōnaehana non – cyanide.

ʻAʻole koi ka plating gula (plating gula) i ka uila, akā waiho i ke gula i ka papa ma o ka hopena kemika i ka hopena.

Loaʻa iā lākou kā lākou pono a me nā mea maikaʻi ʻole. Ma waho aʻe o ka mana inā ʻaʻole paha, hiki i ka papa PCB gula ke hana i nā mānoanoa. ʻOiai e hoʻolōʻihi ʻia ka manawa, kūpono ia no ka hana ʻana i nā papa paʻa. ʻOi aku ka liʻiliʻi o ka wao o ka wai electrogold PCB ma mua o ke gula. Eia nō naʻe, pono i ka ʻōnaehana PCB ka conduction papa holoʻokoʻa, a ʻaʻole kūpono no ka hana ʻana i nā laina kūikawā kūikawā.

ʻO ka mineralization gula he lahilahi loa (ʻoi aku ma mua o 0.2 micron) a haʻahaʻa ka maʻemaʻe o ke gula. Hiki ke hoʻolei ʻia ka wai hana i kahi nui.

Hoʻokahi ʻo PCB plating e hana i nā gula nickel

Hoʻokahi ka hoʻohana ʻana o ka sodium hypophosphite ponoʻī REDOX i ka hopena e hana i kahi papa nickel, ka hoʻohana ʻana i ka hopena hoʻololi e hana i kahi papa gula (kamura (ʻo TSB71 me ka hoʻoliʻiliʻi gula), he hana kemika.

ʻIvy: Ma waho o nā ʻokoʻa i ke kaʻina hana o ka electroplating PCB a me ka plating, eia nā ʻokoʻa aʻe:

ʻO ka PCB electroplated gula papa he mānoanoa, paʻakikī kiʻekiʻe, no laila hoʻohana mau ʻia ia no ka paheʻe pinepine ʻana o ka plug, e like me ka manamana gula kāleka, a pēlā aku.

Hoʻohana ʻia ia no ka kuʻihao manuahi kēpau ma muli o ka maʻalahi o ka pad.
