ʻO ke kaʻina hana hoʻopili electrophoretic kahi hana hoʻopili e hoʻohana ana i kahi kahua uila waho e hana i nā puaʻa a me nā ʻāpana resin i hoʻokuʻu ʻia i ka wai electrophoretic e neʻe i kahi ala kuhikuhi a waiho ma ka ʻili o ka substrate o kekahi o nā electrodes. E nānā kāua i kāna kaʻina hana kumu:

Kaʻina hana

Hoʻokumu nui ʻia ka uhi electrophoresis i ka electrophoresis a me ka electrodeposition. I loko o ke kaʻina hana hoʻopili electrophoretic, neʻe nā ʻāpana pena (nā resins a me nā puaʻa) i ka cathode ma lalo o ka hana o ke kahua uila, aʻo nā mea i hoʻopiʻi ʻole ʻia e neʻe i ka anode. Ke piʻi nā ʻāpana maikaʻi (resins a me nā puaʻa) i ka ʻili o ka cathode (ka mea e uhi ʻia), loaʻa iā lākou nā electrons a hana me nā ion hydroxide e lilo i mau mea hiki ʻole i ka wai, i waiho ʻia ma ka cathode (ka mea e lilo ai. i uhi ʻia) e hana i kahi kiʻi ʻoniʻoni ʻoniʻoni.

Kaʻina hana

ʻO ke kaʻina hana hoʻopili electrophoretic ma ke ʻano he ʻehā mau hana nui:

1. Hoʻomaʻamaʻa mua ma mua o ka uhi ʻana: me ka hoʻomaʻemaʻe mua ʻana, degreasing, wehe ʻana i ka ʻōpala, neutralization, holoi wai, phosphating, passivation a me nā kaʻina hana ʻē aʻe. He mea koʻikoʻi kēia mau kaʻina hana pretreatment i ka maikaʻi a me ka hana o ka uhi. Hoʻopaʻa lākou i ka ʻole o ka ʻaila a me ka ʻōpala ka ʻili o ka mea i uhi ʻia, a ʻo ka kiʻiʻoniʻoni phosphate he densely a me ka crystallized like.
2. Electrophoretic coating: Ma hope o ka pau ʻana o ka pretreatment, hoʻokomo ʻia ka mea hana i loko o ka pahu electrophoretic a hana ʻia ka uhi electrophoretic e ke au pololei. Ma kēia kaʻina hana, e neʻe ana nā ʻāpana pena ma lalo o ka hana o ke kahua uila a waiho ma ka ʻili o ka mea hana.
3. Hoʻomaʻemaʻe ma hope o ka electrophoretic: Ma hope o ka pau ʻana o ka uhi electrophoretic, pono e hoʻomaʻemaʻe ʻia ka mea hana e wehe i ka wai pahu a me nā mea haumia ʻē aʻe i pili i ka ʻili. ʻO ke kaʻina hoʻomaʻemaʻe maʻamau e pili ana i nā ʻanuʻu e like me ka hoʻomaʻemaʻe tank a me ka holoi wai ultrafiltration.
4. Hoʻomaloʻo i ka uhi electrophoretic: ʻO ka hope, ua maloʻo ka mea hana i uhi ʻia me ka electrophoretic coating e hoʻopaʻa ʻia i loko o kahi uhi paʻa. ʻO ka mahana maloʻo a me ka manawa e pili ana i ke ʻano o ka uhi i hoʻohana ʻia a me nā koi o ka mea hana.

Kaʻina hana

ʻO ka uhiʻana he plump,ʻaʻahu, pālahalaha, a maʻalahi, me nā mea hoʻonani maikaʻi a me nā mea pale.

ʻOi aku ka maikaʻi o ka paʻakikī o ka uhi ʻana, adhesion, corrosion resistance, hopena hopena, a me ke komo ʻana ma mua o nā kaʻina hana uhi ʻē aʻe.
ʻO ka hoʻohana ʻana i ka pena wai-soluble, me ka wai ma ke ʻano he mea hoʻoheheʻe, mālama i ka nui o nā mea hoʻoheheʻe organik, hoʻemi i ka pollution ea a me nā pōʻino o ka nohona.
He kiʻekiʻe ka maikaʻi o ka uhi ʻana, liʻiliʻi ka nalowale o ka uhi ʻana, a hiki i ka 90% ~ 95%.

Kaʻina hana hoʻoponopono ʻāpana

ʻO nā kūlana kaʻina hana electrophoretic e loaʻa i nā ʻāpana e like me ke ʻano o ka wai ʻauʻau, ka maʻiʻo paʻa, ka ʻona lehu, MEQ (ka helu o nā millimoles o ka waika i koi ʻia no 100 grams o ka maʻiʻo paʻa o ka pena) a me ka ʻike solvent organik. He mea koʻikoʻi ka hoʻokele ʻana i kēia mau ʻāpana e hōʻoia i ka maikaʻi a me ka hana o ka uhi. I ka manawa like, pono nō hoʻi e hoʻolohe i ka hopena o nā mea e like me ke koho ʻana o ka ʻōnaehana filtration a me ka nui o ka puʻupuʻu e pili ana i ka paʻa o ka wai ʻauʻau a me ka maikaʻi o ka kiʻi pena.

Hoʻomalu

I ka wā o ke kaʻina hana electrophoretic coating, pono e paʻa ka mana o ka mana e pale i ka mana o ka fluctuations voltage i ka maikaʻi o ka uhi.
E nānā mau i ke kūlana o ka pahu electrophoretic a me nā mea hana e hōʻoia i kā lākou hana maʻamau.
E hoʻopaʻa paʻa i nā kaʻina hana electrophoretic coating e hōʻoia i ka maikaʻi a me ka hana o ka uhi i nā koi.
E noʻonoʻo i ka hana palekana e pale aku i nā pōʻino e like me ka uila uila a me ke ahi i ka wā o ke kaʻina hana electrophoretic coating.
