He aha ka hana e pono ai ke hana ma mua o ke kaula wela galvanized

ʻO ka pretreatment electroplating ke kumu o ka electroplating a me ke kī e hōʻoia i ka maikaʻi o ka uea wela wela.Inā ʻaʻole mālama ʻia ka substrate i nā koi i ʻōlelo ʻia ma mua o ka electroplating, ʻoiai me ka hopena electroplating maikaʻi, nā ʻāpana electroplating kūpono a me nā mea hana no ka hoʻoponopono ʻana i nā ʻāpana electroplating, a me nā limahana akamai loa, ʻaʻole hiki ke loaʻa i ka electroplating coating e hoʻokō i nā koi o ka maikaʻi.

Ma mua o ka plating ʻaʻole wale e wehe i ka matrix metala, a me ka noho ʻana o nā aila a hoʻopili i ka hoʻopili ʻana i ka uhi a me nā koi ʻē aʻe o nā mea ʻē aʻe, makemake nō hoʻi e hoʻoneʻe i ka oxide o ka honua, e hana i ka hoʻomaʻemaʻe a me ka hana maʻemaʻe, e hōʻoia i ka uhi ʻana. a paʻa ka substrate me, e like me nā koi o ke ʻano o ka plating, i kekahi manawa e hana i kekahi hana kūikawā ʻē aʻe ma mua o ka plating.

ʻO ke kūlana lawelawe a me ke ola lawelawe o ka metala electrogalvanized a i ʻole nā ​​​​mea pili i pili i ka mānoanoa plating.ʻOi aku ka paʻakikī o nā kūlana hoʻohana a ʻoi aku ka lōʻihi o ke ola lawelawe, ʻoi aku ka mānoanoa o ka papa galvanizing e pono ai.ʻO nā huahana like ʻole, e like me ke kaiapuni kikoʻī (ka mahana, ka haʻahaʻa, ka ua, ka haku mele ʻana, a me nā mea ʻē aʻe) e hoʻoholo ai i ke ola lawelawe i manaʻo ʻia o ka mānoanoa electroplating, ʻo ka mānoanoa makapō ke kumu o nā ʻōpala.Akā inā ʻaʻole lawa ka mānoanoa, ʻaʻole ia e hoʻokō i nā koi ola lawelawe i manaʻo ʻia.

ʻO nā mea hana like ʻole, e like me kā lākou mau pono ponoʻī, i ka hihia o ka hoʻoholo ʻana i ke ʻano plating, e hōʻuluʻulu mua i kahi kahe kaʻina ʻoi aku ka piha a me ke kūpono, nā ʻāpana plating maʻemaʻe, ka hoʻokele plating solution concentration, ka hana maʻamau.Hoʻomaʻamaʻa post-plating no ke kumu o ka hoʻonui ʻana i ka pale, hoʻonaninani a me nā kumu kūikawā ʻē aʻe o nā ʻāpana plating.Ma hopegalvanizing, chromate passivation, a i ʻole nā ​​​​lāʻau hoʻololi ʻē aʻe e koi ʻia e hana i ke ʻano like o ke kiʻi hoʻololi, ʻo ia kekahi o nā kaʻina hana nui e hōʻoia i ka maikaʻi o ka plating.
