Ua aʻo ʻia ke kumu o ka hoʻohemo ʻana o Resist paʻakai S a me kona mana, a ua hoʻohana ʻia ke ʻano o ka fenton oxygen/chemical no ka hoʻoponopono ʻana i ka ʻōpala deplating i loaʻa.E kūʻē iā S. Hōʻike nā hopena i hiki ke hoʻoneʻe i ka chroma 70%.

E kūʻē iā Sʻo // nitrate //ji// Ben //.. Ma ke ʻano he waena o nā kala, sulfur // acid // hoʻohana mau ʻia ka sodium ma ke ʻano he mea pale wai a me ka mea pale ʻalani, a hoʻohana nui ʻia e like me ka wehe ʻana i ka nikela electroplating.E kūʻē iā Shiki ke hoʻoheheʻe i ka uhi ʻana, akā ʻaʻole ia e corrode i ka substrate, a he hopena pale i ka substrate. ʻO kāna kaʻina hana hoʻomākaukau e like me kēia:

 

C6H6 -- HNO3.H2SO4 hui pū ʻia -- nitrate. Base Ben -- trioxygen. Sulphurization. Sulfonation -- paʻakai no ka pale ʻana.

 

1. Ke kumu o ka hoolei ana i ka paakai anti-dye S ma o ka electroplating

 

I ka ʻoihana electroplating, ʻoi aku hoʻi i nā ʻoihana o ka plating metala, hoʻohana nui ʻia ka paʻakai anti-dye S no ka nickel, ke gula a me nā plating ʻē aʻe, akā hoʻohana nui ʻia i ka hana pre-electroplating.

 

I kēia manawa, ʻo ke kaʻina hana deplating nui: mixed nitrate. ʻO ke ala ʻakika, ke ʻano electrolysis, ke ʻano anti-dye paʻakai S. Ma waena o lākou, ʻo ka ʻokoʻa ma waena o ka QING a me ka non-Qing deplating kaʻina i ka anti-dye paʻakai S ke ʻano inā hoʻohana ʻia ʻo NaCN ma ke ʻano he mea paʻakikī. No laila, ʻo ka paʻakai anti-dye S ka mea pono o nā ʻano mea wehe nickel āpau ma ka mākeke i kēia manawa.

 

1, deplating agent ingredients

 

2, ka mana o ka electroplating anti-dyeing paʻakai S

 

Ua like ka waihoʻoluʻu o ka hoʻonā deplating me ka wai ʻōpala i loko o ka chromium kiʻekiʻe, a ʻo ka hoʻonā deplating aia kahi kiʻekiʻe kiʻekiʻe o QING, kahi maʻalahi ke kuhi hewa ʻia i loko o ka wai ʻōpala i loko o ka chromium. Wai, ka hopena. Luna Ho'okele /.. pela.

 

Mai ke kala i hanaia eE kūʻē iā SHe paʻakikī loa ka wehe ʻana, ʻaʻole hiki ke hoʻoneʻe ʻia e ka hoʻomaʻamaʻa mua ʻana o ka wai electroplating e like me ka chlorine maʻamau a me ke ʻano oxygen, ka hopena i ka waihoʻoluʻu melemele koʻikoʻi o ka effluent, e pili ana i ka hoʻokuʻu ʻana o ka wai a hoʻonui i ke kaumaha o ka ʻōnaehana mālama membrane no ka medium. hoohana hou i ka wai. ʻOi aku ka māmā o ka melemele māmā ma nā kūlana ʻakika, ʻoi aku ka ʻeleʻele i nā kūlana kūʻokoʻa a me ka alkaline, a ʻeleʻele ka waihoʻoluʻu mai ka melemele a i ka ʻulaʻula ma hope o ka ʻike ʻana i ka mālamalama.

 

3. Ka mālama ʻana i ka ʻōpala >/ wai i loaʻa ka paʻakai anti-dye

 

Pono e hōʻiliʻili ʻia ka wai a hoʻokaʻawale ʻia. I kēia manawa, ʻaʻole nui nā ala kūpono no ka mālama ʻana i ka wai, e like me ka oxygen/chlorination maʻamau. ʻAʻole hiki i ka sodium acid, oxygen, etc. ke wehe i ka nitrate. Hoʻokani ʻo Ben ma ke kumu ʻo Ben a me Benamine. ʻAʻole hiki ke hoʻoneʻe i ka nitrate i ka adsorption kalapona hoʻōla a me ka flocculant precipitation. Base Ben a me benamine, akā me ka sulfur. Hiki i ka Ferrous acid ke uhi i ka ʻāpana o ke kala, akā e loaʻa ke kala, inā ʻaʻole nui ka wai, hiki ke hoʻoheheʻe ʻia me ka wai hoʻokuʻu ma hope o ka hoʻokuʻu ʻana.

 

Ua hoʻohana ʻia ke kaʻina hana hoʻokahe Fenton e mālama i ka ʻōpala./ wai, a ua aʻo ʻia ka hopena wehe kala o H2O2. Hoʻokaʻawale ʻia ke kaʻina holoʻokoʻa i ʻelua mau pae: pretreatment a me Fenton oxygenation.
