Ka hana mua a me ka electrocoating

Pretreatment a me electrocoating kaʻina kiʻi hiʻona

ʻO ka wehewehe pōkole:

ʻO ka hoʻomaʻamaʻa ʻana i ka uhi ʻana ʻo ia ka hoʻomākaukau ʻana i ka ʻili o ka uhi ʻana ma mua o ka uhi ʻana a ʻo ia ke kumu o ke kaʻina hana uhi holoʻokoʻa.
Hoʻopili pololei ka maikaʻi o ka pretreatment i ka maikaʻi o ka uhi holoʻokoʻa, no laila pono mākou e hoʻolohe iā ia.

Hōʻike huahana

ʻO nā mea like ʻole a me kā lākou huahana i ke kaʻina hana, ka lawe ʻana, ka mālama ʻana, maʻalahi kona ʻili e hana a i ʻole
e hoʻopaʻa i nā mea ʻē, e like me ka machining burr, oxide skin, oil, etc., e pili ana kēia mau mea haumia i ka paʻa o ka uhi a me ka ikaika paʻa me ka matrix. ʻO ka hoʻomaʻamaʻa mua ʻana o ka mea nui ʻO ka pahuhopu ʻo ka wehe ʻana i kēia mau mea a hana i ka hoʻololi ʻana o ka ʻili kemika kūpono e hāʻawi i nā koi kūpono Coating o ka substrate, i mea e hoʻonui ai i ka adhesion o ke kiʻiʻoniʻoni, hoʻolōʻihi i ke ola lawelawe o ke kiʻiʻoniʻoni, Hāʻawi i ka pāʻani piha i ka pale. hopena a me ka hopena hoʻonani o ka uhi.

No laila, e pīpī i ka mea ma mua o ka hana ʻana. Loaʻa ka nui o nā ʻano penei:

Degreasing ma mua o ka uhi ʻana

ʻO ke kila a me kāna mau ʻāpana i ke kaʻina o ka mālama ʻana a me ka lawe ʻana e hoʻohana i ka pale aila antirust, pono e hoʻohana ʻia ka mea hana metala i ke kaha kiʻi ʻana i ka wā e hana ai ke kaomi, pono nā ʻāpana e hoʻopili i ka emulsion i ka wā e mīkini ai, hiki i ka mālama wela ke hoʻopili i ka aila hoʻomaha, ke loaʻa pinepine nā ʻāpana i ka aila. stains a me HanJi o nā lima o ka mea hana, ka momona o nā ʻāpana akā ʻo nā mea haumia e like me ka mau a me ka lepo i hui pū ʻia ʻO kēia mau mea āpau, nā ʻano ʻaila āpau ma nā ʻāpana ʻaʻole wale ke keʻakeʻa i ka hoʻokumu ʻia ʻana o ke kiʻi phosphating, akā pili pū kekahi i ka adhesion o ka ʻO ka hoʻomaloʻo ʻana i ka uhi ʻana i ka hana hoʻonaninani a me ke kūpaʻa ʻana i ka ʻino ʻana i ka papa 3-1 ka papa inoa o ka hoʻomaʻamaʻa mua ʻana o ka pā kila ʻōwili anuanu. Ka hopena o ka uhi electrophoretic cathodic i ka pale ʻana i ka corrosion.

Phosphating

ʻO ka Phosphating kahi hana maʻalahi, hilinaʻi, haʻahaʻa a maʻalahi hoʻi e hoʻomaikaʻi maikaʻi i ka pale ʻana i ka corrosion o ka uhi ʻili metala. Ua hoʻohana nui ʻia ma ka home a me nā ʻāina ʻē, ʻoi aku ka nui o ka uhi kaʻa, kahi i hoʻohana nui ʻia i nā makahiki i hala. Ma kahi o 100% o nā ʻāpana pā lahilahi i ka ʻoihana kaʻa he phosphating ʻO ke kaʻina hana Phosphating e pili ana i ka ʻili metala i hoʻopili ʻia me ka hopena waika i loaʻa ka paʻakai dihydrogen phosphate, ka hopena kemika a hana ʻia i loko o ka ʻili metala paʻa o ka insoluble inorganic compound layer membrane o kahi. ʻO ke ʻano hana hoʻomaʻamaʻa kemika a me ke kiʻiʻoniʻoni i hana ʻia i kapa ʻia ʻo phosphating film.

Kumuhana kiʻiʻoniʻoni Phosphate

Hiki i ka phosphating film ke hāʻawi i kahi kumu kūpono loa no ka uhi ʻana i ka pena, ma muli o kēia hopena:
1) Hāʻawi i kahi maʻemaʻe, ʻaʻahu a me ka momona ʻole ma ke kumu o ka degreasing piha
2) hoʻonui i ka hoʻopili ʻana o ka kiʻiʻoniʻoni organik i ka substrate ma muli o ka hana kino a me ka hana kemika ʻAʻole paʻakikī ke hoʻomaopopo ʻana i ka hoʻonui ʻana o ke ʻano porous o ke kiʻi phosphating i ka ʻili o ka substrate, no laila e hoʻonui like ka wahi pili ma waena o nā mea ʻelua, a ua hoʻokumu ʻia ka permeability i waena o nā papa kiʻiʻoniʻoni ʻelua. I ka manawa like, hoʻonui ka pilina ma waena o ka resin unsaturated a me ka kristal phosphate i kona ikaika paʻa
3) hāʻawi i kahi paʻa kaʻawale non-conductive papa, i ka manawa o ka uhi ʻana i ka pōʻino, loaʻa iā ia ke kuleana o ka corrosion inhibition, ʻoi aku hoʻi no ka incision anode ʻO ka helu mua e haʻalele pinepine wale ʻia i ka maikaʻi loa o ka aila e hana i kahi kiʻiʻoniʻoni phosphating maikaʻi. ʻO ke kiʻiʻoniʻoni phosphating ka hopena intuitive loa o ka ʻenehana pretreatment o ka mea hilinaʻi ponoʻī.
