ʻO Surley kahi hōʻiliʻili opretreatment a me nā hana electrophoresis Hale hoolele umu ʻōnaehana lawe pae hoʻāʻo ʻauʻau ʻenehana pale kaiapuni Mea lako hale hanakaila i loko o ka hale kūʻai hoʻokahi.
Ka hana mua a me ka electrocoating
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:
Kumukānāwai 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 papa hoʻokaʻawale paʻa ʻole conductive, i ka manawa o ka pōʻino o ka uhi, loaʻa iā ia ke kuleana o ka corrosion inhibition, ʻoi aku hoʻi no ka incision anode. ʻO ke kiʻiʻoniʻoni phosphating ka hopena intuitive loa o ka ʻenehana pretreatment o ka mea hilinaʻi ponoʻī.
