Paʻa ʻili
he pepa kila kalapona haʻahaʻa i uhi ʻia me kahi ʻāpana lahilahi o ka pī, ma ke ʻano maʻamau mai ka 0.4 a i ka 4 micrometers ka mānoanoa, me nā paona hoʻopaʻa tin ma waena o 5.6 a me 44.8 grams no ka mika square. Hāʻawi ka uhi ʻia i kahi ʻōlinolino, keʻokeʻo keʻokeʻo a me ka pale ʻana i ka corrosion maikaʻi loa, ʻoi aku ka paʻa ʻana o ka ʻili. Paʻa kemika a paʻa ʻole ka tin, no laila palekana ia no ka hoʻopili pololei ʻana i ka meaʻai. ʻO ke kaʻina hana e pili ana i ka acid electroplating a i ʻole ka wela wela, e ukali pinepine ʻia e ka passivation a me ka ʻaila e hoʻomaikaʻi i ka lōʻihi.
| Aspect | Paʻa ʻili | Pepa Galvanized |
|---|---|---|
| Mea hoolele | Pin (māmā, wahi hehee haʻahaʻa, paʻa kemika) | Zinc (ʻoi aku ka paʻakikī, hana kemika, hana i ka hopena anode kaumaha) |
| Pale ʻino | Maikaʻi, hilinaʻi i ke kaʻawale kino; hiki i ka oxidation inā pohō ka uhi | Maikaʻi, pale inā ʻino ka uhi ʻana, paʻa i nā kūlana paʻakikī |
| Kaʻawaʻawa | ʻAʻole ʻona, palekana no ka pili ʻana i ka meaʻai | ʻAʻole kūpono no ka hoʻopili ʻana i ka meaʻai |
| Ka nana aku | He ʻulaʻula, keʻokeʻo keʻokeʻo, kūpono no ka paʻi ʻana a me ka uhi ʻana | ʻO ka hina hina, ʻaʻole ʻoluʻolu i ka nani, ʻaʻole kūpono no nā kumu hoʻonaninani |
| Hana Hana | ʻoluʻolu, kūpono no ke kuʻi ʻana, hoʻopololei, a me ka hana ʻana; oluolu e wiliwili | ʻOi aku ka paʻakikī, ʻoi aku ka maikaʻi no ka wili a me ka hoʻopaʻa ʻana, ʻoi aku ka liʻiliʻi o ka ductile no nā ʻano paʻakikī |
| Mānoanoa maʻamau | 0.15–0.3 mm, loaʻa nā nui maʻamau 0.2, 0.23, 0.25, 0.28 mm | ʻO nā lau mānoanoa, hoʻohana pinepine ʻia no nā hana kaumaha |
ʻO ka tinplate a me ka pepa galvanized he mau mea kila i hoʻohana ʻia no ka hana ʻana i nā kini a me nā ʻeke, akā he ʻokoʻa ko lākou mau uhi a me nā noi.
Tinplate: Hoʻopili ʻia me ka tin, ʻaʻohe mea ʻawaʻawa a kūpono no nā kīʻai meaʻai, e hāʻawi ana i ke kūpaʻa ʻino maikaʻi a kūpono no ka paʻi ʻana. He palupalu a maʻalahi ke hana i nā ʻano paʻakikī.
Pepa Galvanized: Hoʻopili ʻia me ka zinc, hāʻawi ia i ke kūpaʻa ʻoi aku ka maikaʻi no ka hoʻohana ʻana i waho, e like me nā ʻeke, akā ʻoi aku ka paʻakikī a ʻaʻole kūpono no ka hoʻopili ʻana i ka meaʻai ma muli o ka hiki ʻana o ka zinc leaching.
ʻO Kina ka mea hoʻolako alakaʻi o 3 ʻāpana Tin Can Making Machine a me Aerosol Can Making Machine, Changtai Intelligent Equipment Co., Ltd. he mea akamai i ka hana ʻana i ka mīkini hiki ke hana i ka mīkini. hāʻawi i nā pae palekana kiʻekiʻe a me ka palekana kūpono no nā mea hana.
