He aha nā mea e mālama ai i ke kūʻai ʻana a me ka hoʻohana ʻana i ka alumini

1. I ke koho ʻana, e nānā i ka lā ex-factory a me nā kikoʻī o ka alumini, a me ka inoa huahana a me ka helu laikini hana e pili ana.A e nānā i ke kala ʻili o ka alumini e ʻike inā ʻoi aku ka maikaʻi o ka ʻōlinolino.A inā paha he mau hemahema ma ka ʻili, inā aia, ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka mea alumini piha piha no ke kūʻai ʻana.Eia kekahi, ʻaʻole e emi ka mānoanoa o ka mea alumini ma mua o 1 mm, ʻaʻole e emi ka mānoanoa o ke kiʻiʻoniʻoni ma mua o 10um, a ʻaʻole pono ka mānoanoa o ka uhi ma mua o 40 ~ 120um.

2. Ke koho ʻana i nā mea alumini, ʻoi aku ka maikaʻi o ke koho ʻana i nā huahana me ka hana corrosion maikaʻi.Ma kēia ala, i ka wā e hoʻohana ai, ʻoi aku ka ikaika o ka hana.A ʻaʻole hiki ke hoʻomaʻemaʻe ʻia ka ʻili o ka mea alumini me nā mea paʻakikī ke hoʻomaʻemaʻe.E hōʻino kēia i ka ʻili o ka mea alumini, hiki ke holoi ʻia me ka wai a me ke kopa.

3. Ma hope o ka extrusion o ka alumini, aia kekahi mau hemahema.Loaʻa kēia ʻano inā ʻaʻole i oʻo loa ke kaʻina extrusion.A ʻo ka mānoanoa o ke kiʻi ʻoniʻoni he lahilahi loa

4. Ma kahi o 10um.A i ka laʻana, e ʻike pono e nānā i ka ʻili o ka alumini, inā he laikini hana a
