ʻĀpana keleawe i hoʻopaʻa ʻia

II. Nā hiʻohiʻona uhi:

1) Kaulike like

A) Electroplating tinning: He maikaʻi ke ʻano o ka uhi ʻana, a hiki iā ia ke hana i kahi ʻāpana tinning a me ka palupalu ma luna o ka ʻili.kaula keleawe. Maikaʻi no nā ʻāpana keleawe me nā ʻano paʻakikī a me nā ʻili ʻole, hiki ke uhi maikaʻi ʻia, kūpono ia no nā hiʻohiʻona noiʻi me nā koi kiʻekiʻe no ka uhi ʻana i ka ʻano like ʻole.

B) ʻO ka ʻili wela: He ʻilihune ke ʻano o ka uhi ʻana, a hiki ke ʻike ʻia ka mānoanoa o ka uhi ʻole ma nā kihi a me nā ʻaoʻao.kaula keleawe. Eia nō naʻe, no kekahi mau manawa ʻaʻole koʻikoʻi nā koi no ka hoʻohui ʻana o ka uhi ʻana, liʻiliʻi ka hopena.
2) Mānoanoa uhi:

A) Electroplating tinning: He lahilahi ka mānoanoa o ka uhi, ma waena o kekahi mau microns a me ʻumi mau microns, a hiki ke hoʻokele pololei ʻia e like me nā pono kikoʻī.

B) ʻO ka ʻili wela wela: ʻoi aku ka mānoanoa o ka uhi ʻana, ma waena o nā ʻumi microns a me nā haneli mau microns, hiki ke hāʻawi i ke kūpaʻa corrosion maikaʻi aʻe a me ke kūpaʻa ʻaʻahu.nā kaula keleawe, akā ʻaʻole kūpono paha ia no kekahi mau noi me nā palena paʻa i ka mānoanoa.
III. Hana pono hana

1) Electroplating tin plating: He paʻakikī ke kaʻina hana, e koi ana i nā kaʻina he nui e like me ka pre-treatment, electroplating, a me ka post-treatment. He lohi ka wikiwiki o ka hana a ʻaʻole kūpono no ka hana nui a me ka hana kiʻekiʻe. Eia nō naʻe, no kekahi mau mea liʻiliʻi a me nā pono hana maʻamau, hiki i ka electroplating tin plating ke kūpono kūpono.

2) He mea maʻalahi ke kaʻina hana. Hiki ke hoʻopau ʻia ke kaʻina hoʻopaʻa ʻia ma ka hoʻolulu ʻana i kakaula keleawei loko o ke kini wai. He wikiwiki ka wikiwiki a hiki ke hoʻokō i nā pono o ka hana nui.
IV. Ka ikaika pili:

1) Electroplating tin plating: ʻO ka ikaika hoʻopaʻa ma waena o ka uhi a me kakaula keleaweikaika ka substrate. ʻO kēia ke kumu o ka hana ʻana o nā kinikini i nā mea hoʻopaʻa kemika me nā ʻātoma ma ka ʻili o ke kaula keleawe ma lalo o ka hana a ke kahua uila i ka wā o ka hana electroplating, e paʻakikī ai ka hāʻule ʻana o ka uhi5.

2) ʻO ka hoʻopaʻa ʻana i ka ipu wela: He maikaʻi nō ka ikaika o ka hoʻopaʻa ʻana, akā i kekahi mau hihia, ma muli o ka hopena paʻakikī ma waena o ka wai tin a me ka ʻili o ka wai.kaula keleawei loko o ke kaʻina hana hoʻoheheʻe wela, hiki ke ʻike ʻia kekahi pores liʻiliʻi a i ʻole nā ​​hemahema, e pili ana i ka ikaika paʻa. Eia nō naʻe, ma hope o ka mālama pono ʻana, hiki i ka ikaika hoʻopaʻa ʻana o ka pā wela wela ke hoʻokō i nā koi o ka hapa nui o nā noi.
V. ʻAi ʻino:

1) Electroplating tinning: Ma muli o ka uhi lahilahi, ua nāwaliwali kona kūpaʻa corrosion. Eia naʻe, inā e hoʻomalu pono ʻia ke kaʻina hana electroplating a hoʻokō ʻia ka hoʻomaʻamaʻa ʻana ma hope o ka hoʻomaʻamaʻa ʻana, e like me ka passivation, ʻo ke kūpaʻa ʻana o ka corrosion.kāʻei keleawe ʻumekehiki ke hoʻomaikaʻi ʻia

2) Hoʻohu wela: ʻOi aku ka mānoanoa o ka uhi ʻana, hiki ke hāʻawi i ka pale kūʻē corrosion maikaʻi aʻe no kakaula keleawe. I nā kūlana kaiapuni koʻikoʻi, e like me nā kaiapuni humid a corrosive, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion o ka wela wela.kāʻei keleawe ʻumekeʻoi aku ka maopopo5.
VI. Koina

1) Electroplating tinning: He ʻuʻuku liʻiliʻi ka hoʻolilo ʻana i nā mea hana, akā ma muli o ke kaʻina hana paʻakikī, ʻoi aku ka nui o ka uila a me nā reagents kemika, a loaʻa iā ia nā koi kiʻekiʻe no ke kaiapuni hana a me nā mea hana, no laila ke kiʻekiʻe ke kumu kūʻai.

2) Hot-dip tinning: He nui ka hoʻokomo ʻana o nā mea hana, a pono ke kūkulu ʻia nā umu wela wela a me nā mea hana ʻē aʻe, akā maʻalahi ke kaʻina hana a me ka liʻiliʻi o ka hoʻohana ʻana i nā mea waiwai, no laila ʻoi aku ka haʻahaʻa o ke kumukūʻai. hana nui.

Ke koho ʻana i kahikāʻei keleawe ʻumekekūpono i kāu hiʻohiʻona noi e pono ai ka noʻonoʻo piha ʻana i nā mea he nui e like me nā waiwai uila, nā waiwai mechanical, ka pale ʻana i ka corrosion, ke kaʻina hana, ke kumu kūʻai a me ka pale ʻana i ke kaiapuni. E like me nā pono kikoʻī, e kaupaona i nā pono a me nā mea ʻino o nā ʻano āpau a koho i ka mea kūpono loakāʻei keleawe ʻumekee hōʻoia i ka hana a me ka maikaʻi o ka huahana.
