1. nā mea maʻamau i hoʻohana ʻia i ke kaʻina metala
Ke kila ʻōwili anuanu
Hoʻohana nui ʻia nā huahana Cold-rolled i ke kūkulu ʻana, ʻoihana māmā, nā mea hana hale, electromechanical, kaʻa a me nā ʻoihana ʻē aʻe.Loaʻa i ka huahana nā hiʻohiʻona o ka pololei kiʻekiʻe o ke ʻano a me nā ana geometric, ka hana paʻa o ka ʻōwili like, a me ka maikaʻi o ka ʻili.
SGCC
Nui ka laulā o nā lako hale liʻiliʻi, kahi maikaʻi ke ʻano.Nā helu Spangle: spangle maʻamau maʻamau a me ka spangle liʻiliʻi a hiki ke ʻike ʻia e kona uhi ʻia: no ka laʻana, Z12 ʻo ia ka nui o ka uhi ʻaoʻao ʻelua he 120g/mm2.
He kaʻina hana hoʻoheheʻe hoʻohaʻahaʻa ʻo SGCC i ka wā o ka galvanizing wela, a ʻoi aku ka paʻakikī o ka paʻakikī, no laila ʻaʻole maikaʻi ka hana ʻana o ka metala me ka SECC.ʻOi aku ka mānoanoa o ka papa zinc o SGCC ma mua o ka SGCC, akā ʻoi aku ka maʻalahi o ka hana inā ʻoi aku ka mānoanoa o ka papa zinc.Wehe ʻia ʻo Zinc, a ʻoi aku ka maikaʻi o SECC no nā ʻāpana paʻakikī.
5052 Aluminum huila
Loaʻa i ka 5052 alumini alumini kekahi o nā hiʻohiʻona wili maikaʻi loa, loaʻa nā ʻano hoʻopau maikaʻi loa, maikaʻi loa ka pale ʻana i ka wai paʻakai, akā ʻaʻole maʻalahi ka mīkini.ʻAʻole hiki ke hoʻomaʻamaʻa ʻia kēia huila a hiki ke hoʻoikaika ʻia me ka hoʻohana ʻana i ke kaʻina hana paʻakikī, ʻo 5052-H32 ka hana maʻamau (no ka ʻike hou aku e pili ana i ka paʻakikī hana, e ʻoluʻolu e kipa i kā mākou ʻatikala e pili ana i ka 5052 alumini alumini. ʻO ke ʻano 5052 alumini ka mea ikaika loa o nā mea hoʻoheheʻe hiki ʻole i ka wela no kēia mau kumu, hana maikaʻi loa ʻo 5052 alumini e like me ka lau a me ka metala, e hui pū ana me ka hoʻonui ʻana i ka ikaika Al 5052. 'o ia ho'i, 'a'ole hiki ke ho'opō'ino i ka wai pa'akai e like me nā alumini alumini'ē a'e, e lilo ia i mea koho maika'i loa no nā noi kai.
ʻAi ʻole 304
ʻO ka SUS 304 he kila kila kila i hoʻohana nui ʻia no ka hana ʻana i nā mea hana a me nā ʻāpana e pono ai ka hui pū ʻana o nā waiwai (ke kūpaʻa corrosion a me ka formability).
He kila kila 316
SUS316 hoʻohana i ka hana ʻana i nā Blades, nā ʻāpana mīkini, nā mea hoʻomaʻemaʻe ʻaila, nā bolts, nā nati, nā lāʻau pamu, nā papa ʻaina papa 1 (nā ʻoki a me ka ʻōpala)
2. ʻO nā lāʻau lapaʻau maʻamau no ka pepa metala
Elele uila:
ʻO ka ʻenehana o ka waiho ʻana i nā pale metala i hoʻopili maikaʻi ʻia me nā mea matrix hana like ʻole ma nā huahana mechanical e ka electrolysis.ʻOi aku ka like o ka papa electroplating ma mua o ka papa wela, a ʻoi aku ka lahilahi, mai nā microns a hiki i nā ʻumi microns.Ma ka electroplating, hiki ke kiʻi ʻia nā ʻāpana ʻili o nā mea hana ma nā huahana mechanical, a hiki ke hoʻoponopono ʻia nā mea hana i hoʻopaʻa ʻia a hana hewa ʻia.Eia kekahi, aia nā hana like ʻole e like me nā pono electroplating.Eia kekahi laʻana:
1. Copper plating: hoʻohana ʻia ma ke ʻano he kumu no ka hoʻomaikaʻi ʻana i ka adhesion a me ka corrosion resistance o ka papa electroplating.
2. Nickel plating: hoʻohana ʻia ma ke ʻano he kumu mua a i ʻole he hiʻohiʻona e hoʻomaikaʻi i ka pale ʻana i ka corrosion a me ke kūpaʻa ʻana (ma waena o lākou, ʻoi aku ka pale ʻana o ka nickel kemikal ma mua o ka chrome plating i ka ʻenehana hou).
3. Hoʻopili gula: E hoʻomaikaʻi i ke kūpaʻa pili conductive a hoʻomaikaʻi i ka lawe ʻana i ka hōʻailona.
4. Palladium-nickel plating: Hoʻomaikaʻi i ke kūpaʻa hoʻopili conductive, hoʻomaikaʻi i ka hoʻouna ʻana i ka hōʻailona, a ʻoi aku ka ʻoi aku o ka pale ʻana ma mua o ke gula.
5. ʻO ka pahu a me ke kepau: e hoʻomaikaʻi i ka hiki ke hoʻopaʻa ʻia, a e hoʻololi koke ʻia e nā mea pani ʻē aʻe (no ka mea, ua uhi ʻia ka hapa nui o ke kēpau me ka tin a me ka matte tin).
ʻO ka pauka/ka uhi ʻia:
1. Hiki ke loaʻa i kahi uhi mānoanoa e ka uhi hoʻokahi.No ka laʻana, pono e hoʻopili ʻia kahi uhi o 100-300 μm i 4 a 6 mau manawa me kahi pale solvent maʻamau, ʻoiai hiki ke hoʻokō ʻia kēia mānoanoa me ka uhi pauka i ka manawa hoʻokahi..He maikaʻi loa ka pale ʻana o ka corrosion o ka uhi.(Ke paipai nei mākou iā ʻoe e hoʻolohe i ka moʻokāki lehulehu "Mechanical Engineer", a e ʻike i ka ʻike o nā waiwai maloʻo a me nā ʻike ʻoihana i ka hiki ke hiki)
2. ʻAʻohe mea hoʻoheheʻe a ʻaʻohe haumia o nā ʻōpala ʻekolu i ka pauka, kahi e hoʻomaikaʻi ai i nā kūlana hana a me ka maʻemaʻe.
3. Hoʻohana ʻia ka ʻenehana hou e like me ka pauka electrostatic spraying, kahi kiʻekiʻe kiʻekiʻe a kūpono hoʻi no ka pena laina laina hui;kiʻekiʻe ka nui o ka hoʻohana ʻana i ka pauda a hiki ke hana hou ʻia.
4. Ma waho aʻe o ka thermosetting epoxy, polyester, acrylic, aia ka nui o ka thermoplastic grease-resistant hiki ke hoʻohana ʻia e like me ka pauka, e like me ka polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate a me nā ʻano Fluorine resin, etc.
Electrophoresis
Loaʻa i ka kiʻi pena electrophoretic nā mea maikaʻi o ka uhi piha, ʻaʻahu, pālahalaha a maʻalahi.ʻOi aku ka maikaʻi o ka paʻakikī, adhesion, corrosion resistance, hopena hopena a me ke komo ʻana o ka kiʻi pena electrophoretic ma mua o nā kaʻina hana uhi ʻē aʻe.
(1) ʻO ka hoʻohana ʻana i ka pena wai a me ka wai e like me ka dissolving medium e mālama i ka nui o nā mea hoʻoheheʻe organik, e hōʻemi nui i ka haumia o ka ea a me nā pōʻino o ke kaiapuni, palekana a maʻemaʻe, a pale i ka pilikia huna o ke ahi;
(2) He kiʻekiʻe ka maikaʻi o ka uhi ʻana, liʻiliʻi ka nalowale o ka uhi ʻana, a hiki i ka helu hoʻohana o ka uhi ke hiki i 90% a 95%;
(3) ʻO ka mānoanoa o ke kiʻiʻoniʻoni heʻaʻahu, ikaika ka pili, a maikaʻi ka maikaʻi o ka uhi.Hiki i nā ʻāpana āpau o ka mea hana, e like me nā papa o loko, nā puʻu, nā welds, a me nā mea ʻē aʻe, hiki ke loaʻa i kahi kiʻi ʻoniʻoni ʻoniʻoni a maʻemaʻe, kahi e hoʻonā ai i ka pilikia o nā ʻano hana ʻē aʻe no nā mea hana paʻakikī.nā pilikia o ka uhi ʻana;
(4) Hiki ke hoʻokō ʻia ka hana hoʻomau kiʻekiʻe i ke kūkulu ʻana, kahi e hoʻomaikaʻi nui ai i ka hana hana;
(5) He paʻakikī nā mea hana, he kiʻekiʻe ke kumukūʻai hoʻopukapuka, nui ka hoʻohana ʻana i ka mana, he kiʻekiʻe ka mahana e pono ai no ka hoʻomaloʻo ʻana a me ka hoʻōla ʻana, paʻakikī ka hoʻokele ʻana i ka pena a me ka uhi ʻana, paʻa nā kūlana kūkulu, a koi ʻia ka mālama ʻana i ka wai. ;
(6) Hiki ke hoʻohana wale i ka pena wai-soluble, a ʻaʻole hiki ke hoʻololi ʻia ke kala i ka wā o ke kaʻina hana, a paʻakikī ka paʻa ʻana o ka pena ma hope o ka mālama ʻana no ka manawa lōʻihi.(7) He paʻakikī ka mea hoʻopili electrophoretic a he kiʻekiʻe ka ʻenehana ʻenehana, kahi kūpono no ka hana ʻana i ke kala paʻa.
