Nā ʻāpana liʻiliʻi Galvanizing laina (Robort)

ʻO ke galvanizing o nā ʻāpana liʻiliʻi he ʻāpana koʻikoʻi ia o ka ʻoihana galvanizing, me nā ʻāpana maʻamau, nā ʻāpana kila malleable, nā pāpale kila, nā mea hana mana a me nā ʻāpana like ʻole. Ma muli o kona mahana hana kiʻekiʻe, ka haumia koʻikoʻi, nā lako maʻalahi, kahi hana maʻalahi a me ka ikaika hana kiʻekiʻe o nā limahana. Me ka holomua o ka nohona a me ka piʻi nui ʻana o nā kumukūʻai hana, pono koke ka ʻoihana galvanizing ʻāpana liʻiliʻi e hoʻololi i ke kūlana o kēia manawa, kahi e hoʻolaha ai i nā koi wikiwiki no nā kaʻina hana mālama ikehu hou a me nā lako hana kūpono. ʻO ka mea mua, ma o ka nānā ʻana ma ka pūnaewele, loaʻa iā mākou kahi ʻike mua o ke kaʻina hana a me ke kūlana hana o nā ʻāpana liʻiliʻi o ka galvanizing wela.
I hui pū ʻia me nā hoʻokolohua, ua hoʻoholo ʻia nā palena hana o kēlā me kēia ʻāpana i ka hana ʻana o nā ʻāpana liʻiliʻi o ka galvanizing wela-dip. I kēia manawa, ua hoʻohana ʻia nā ʻāpana liʻiliʻi i ka galvanizing wela-dip i ka mahana kiʻekiʻe i ka hana ʻana, ma mua o ka mahana galvanizing wela-dip kuʻuna e hiki ai ke hana i ka maikaʻi o ka uhi ʻana. Ma o ka noiʻi ʻana i ka zinc plating a me ke kaʻina centrifugal, ua hoʻoholo ʻia nā palena ʻenehana o nā ʻāpana liʻiliʻi o ka plating wela-dip ma 450 ℃ mahana plating zinc kuʻuna.
ʻO ka lua, e like me nā palena hana i luna, ua hoʻolālā ʻia ka mea hana galvanizing rotary, ka mea hana pretreatment a me ka mea hana post-treatment. Hoʻomaʻalahi ka mīkini galvanizing Rotary i ke kaʻina hana o ka galvanizing a me ka centrifugation, a hoʻohui i ka galvanizing a me ka centrifugation. Hāʻule pololei ka wai zinc i hoʻokaʻawale ʻia e ka centrifugation i loko o ka ipu zinc, kahi e hōʻemi ai i ka nalowale wela a me ka hana ʻana o ka lehu zinc. Eia kekahi, ua lako me kahi ipu zinc annular, kahi e hoʻomaikaʻi ai i ka pono hana, hoʻokō i nā koi o nā palena hana o ka plating wela wela kuʻuna, a hiki ke hoʻopau i ka plating wela o nā ʻāpana liʻiliʻi ma ka mahana kuʻuna (450 ℃); Ua hoʻolālā ʻia ka mea hana pretreatment me ka pahu hexagonal a me ka gantry travelling trolley structure, nona ka pono pretreatment kiʻekiʻe; Hoʻoponopono ka mea hana post-treatment i ka pilikia o ka maikaʻi o ka uhi ʻana i hoʻokumu ʻia e ka hoʻokuʻi ʻino ma waena o nā ʻāpana hana o nā lako hana post-treatment o kēia manawa, a hoʻokō ka hoʻolālā i nā pono o ka galvanizing.
