4 mau ala e aʻo ai iā ʻoe e hoʻokaʻawale i ka maikaʻi o ka pahu alumini cigarette uila

1. Nānā ʻike

Inā hōʻailona ʻia ka helu maʻamau o ka huahana a me ka helu laikini hana ma ka ʻaoʻao alumini a me ka ʻeke.

2. Ka maikaʻi o ka ʻili

Ma waho aʻe o ka maʻemaʻe, ʻaʻole pono e ʻae ʻia ka ʻili o ka ʻaoʻao alumini e loaʻa nā hemahema e like me nā māwae, peeling, corrosion a me nā ʻūhū, akā nā hemahema pū kekahi e like me nā wahi corrosion, nā uila uila, nā ʻeleʻele, a me ka peeling film oxide.

3. Oxide film mānoanoa

Hoʻokumu ʻia ka kiʻiʻoniʻoni oxide o ka profile alumini i ka anodizing, nona ka hana o ka pale a me ka hoʻonaninani, a hiki ke ʻike ʻia e kahi ana mānoanoa o kēia manawa.

4. Ka maikaʻi o ke sila

Nui nā hakahaka ma ka ʻili o ka ʻaoʻao alumini ma hope o ka anodization.Inā ʻaʻole i hoʻopaʻa ʻia a ʻaʻole i hoʻopaʻa maikaʻi ʻia, e hoʻemi ʻia ke kūpaʻa corrosion o ka profile alumini.ʻO nā ʻano hana maʻamau no ka hoʻopaʻa ʻana i ka maikaʻi ʻo ia ke ʻano leaching acid, ke ala komo a me ke ʻano phosphobutyric acid.

Hoʻohana maʻamau ʻia ke ʻano leaching acid i ka nānā ʻana ma ka pūnaewele, ʻo ia hoʻi, ʻāwili ʻia ka ʻili o ka ʻaoʻao alumini me ka acetone e wehe ai i ka aila a me ka lepo, a ʻo ka waikawa nitric me ka ratio volume o 50% e hāʻule i ka ʻili a me ka mālie. holoi ʻia.Ma hope o 1 minuke, holoi ʻia ka wai nitric me ka wai, a laila holoi i ka maloʻo, hoʻoheheʻe i kahi kulu o ka syrup poni lapaʻau ma luna o ka ʻili, ma hope o 1 mau minuke, holoi i ka syrup poni a hoʻomaʻemaʻe pono i ka ʻili, e nānā pono i nā meheu i koe, ka ʻO ka ʻaoʻao alumini me ka hoʻopaʻa maikaʻi ʻole e waiho i nā ʻāpana ʻike, a ʻoi aku ka nui o ke kaumaha, ʻoi aku ka maikaʻi o ka sila.ka ino.
