Hot-dip galvanizing, aia ma nā wela kiʻekiʻe e hoʻoheheʻe ai ka zinc ingots, i hoʻokomo ʻia i loko o ka mea kōkua, a laila hoʻokomo ʻia ke ʻano metala i loko o ka ʻauʻau zinc plating, i hoʻopili ʻia ka lālā metala i kahi papa ma ka papa zinc.ʻO ka maikaʻi galvanized wela e pili ana i kona hiki ke mālama, ʻoi aku ka maikaʻi o ka adhesion a me ka paʻakikī o ka papa galvanized.

ʻO ka galvanizing anuanu he hopena paʻakai zinc ma ka electrolysis, i ka plating ma ka uhi, ma ke ʻano nui, ʻaʻohe wela, ʻo ka nui o ka zinc i ʻike pinepine ʻole ʻia i kahi ʻāina humid e maʻalahi loa e hāʻule.ʻO ke anuanu galvanizing kino lapaʻau, wale i loko o ka ili palaki i ka papa o ka zinc, zinc ka uhi maʻalahi e hāʻule i ka hoʻohana 'ana i ka wela-luu galvanized kūkulu.

Kaʻina hana o ka wela-dip galvanizing a me ke anu

Hoʻokomo ʻia ʻo Hot dip galvanized i loko o ka wai zinc dissolved workpiece degreasing, pickling, dipping, hoʻomaloʻo i kekahi manawa a waiho i mua.

ʻO Cold galvanizing, i kapa ʻia ʻo electro-galvanized, ʻo ia ka hoʻohana ʻana i ka mea electrolysis i ka mea hana i loko o ka hoʻohui ʻana o ka wai paʻakai zinc, ma hope o ka degreasing, pickling, a me ka hoʻopili ʻana i ka electrode maikaʻi ʻole o ka mea electrolytic;ʻO ka pā zinc i kau ʻia ma ka ʻaoʻao ʻaoʻao o ka mea hana ua hoʻopili ʻia i loko o ka mea electrolytic ka electrode maikaʻi, ua hoʻohuli ʻia ka mana, kahi au mai ka electrode maikaʻi i ka neʻe ʻana i ka neʻe ʻino, e waiho ʻia ma luna o ka mea hana me kahi papa zinc. .

ʻO ke ʻano o ka galvanizing wela a me ka galvanizing anu

Cold galvanizing nana oi laumania, alohilohi, kala passivation kaʻina plating papa he melemele-'ōmaʻomaʻo i ka waihoʻoluʻu, ua waihoʻoluʻu.He polū-keʻokeʻo a keʻokeʻo paha me ke kaʻina passivation keʻokeʻo he ʻōmaʻomaʻo, keʻokeʻo kaʻina passivation uhi keʻokeʻo a ʻo ka lā nui ke kihi kala.ʻO nā ʻaoʻao angular mea hana paʻakikī e pili ana i ka "wela uila" mai ka pōʻeleʻele, nā ʻāpana o ka papa zinc mānoanoa.He mea maʻalahi ka paena kihi ʻo Yin e hana i kahi ʻāpana hina hina i kēia manawa a ʻoi aku ka lahilahi o ka ʻāpana zinc.ʻO ka mea hana maʻamau zinc tumor, caking phenomenon.

Hot dip galvanized nana i ka li'ili'i 'o'ole'a i ho'ohālikelike 'ia me ka electro-galvanized, silvery ke'oke'o, nana prone ka'ina waterlines a me kekahi mau kulu o ka ma'i ma'i 'oi aku ka maopopo, o ka oi aku ma ka hopena o ka workpiece.ʻO ka papa zinc galvanized wela ma mua o kekahi mau manawa o ka pale corrosion mānoanoa electro-galvanized ʻoi aku ka nui o nā manawa o ka electro-galvanized.
