Chiyambi: Core Material for Lightweight Engineering

Chojambula cha aluminiyamu cha uchi ndiye zida zapadera zomwe zimagwiritsidwa ntchito popanga zitsulo za aluminiyumu za uchi. Monga momwe zimakhalira opepuka sangweji dongosolo pachimake, Chisa chimatha kuuma mwapadera kwambiri komanso mphamvu zenizeni kudzera mu geometry yake yapadera ya hexagonal.. Amagwiritsidwa ntchito kwambiri m'minda yomwe ili ndi zofunikira zokhwima zolemera, kuuma, ndi kutopa kuchita, monga magalimoto apamlengalenga, mayendedwe a njanji yothamanga kwambiri, ship superstructures, ndi machitidwe apamwamba opangira nsalu zotchinga.

Bukuli likufuna kufotokoza mwadongosolo, kuchokera kumalingaliro azinthu sayansi ndi uinjiniya wopanga, ndi metallurgical katundu wa aloyi, pamwamba mankhwala matekinoloje, mwatsatanetsatane akugubuduza njira, zizindikiro zazikulu za ntchito, ndi ubale wawo ndi khalidwe lomaliza lachisa cha uchi. Imagwira ntchito ngati ukadaulo waukadaulo kutengera machitidwe amakampani ndi miyezo ya mainjiniya, akatswiri ogula zinthu, ndi opanga.

1. Chisa cha Aluminiyamu Chojambula: Tanthauzo ndi Ntchito Yachikulu

Chojambula cha aluminiyamu cha uchi chimatanthawuza ku mzere wa aluminiyamu womwe wakhalapo zozizira ndendende mpaka zoyezera zoonda kwambiri (pafupifupi 0.03-0.08mm)ndikukutidwa ndi zokutira zapadera (E.g., chromate). Ntchito yake yayikulu ndikupanga makoma a ma cell a uchi wa hexagonal omwe amakonzedwa pafupipafupi kudzera munjira zopangira: nthawi zomatira kusindikiza, stacking, kunyezera, ndi kukulitsa.

Ntchito Yofunikira ya Foil: Makulidwe a zojambulazo (t) mwachindunji chimatsimikizira mtanda-gawo la makoma selo ndipo ndi chinthu choyambirirakumakhudza kwenikweni kukakamira mphamvu ndi kukameta ubweya. Mphamvu zokolola zakuthupi (σ) imatsimikizira malire onyamula katundu.

3. Chithandizo cha Chromate: Kufunika, Chinthu, ndi Process Control

Zolemba za aluminiyamu zosasamalidwa zimakhala ndi filimu yachilengedwe ya okusayidi yomwe imapereka zomatira zofooka komanso zosakhazikika ku zomatira za polima.. Chithandizo cha kutembenuka kwa chromate chimapangidwa ndi mankhwala a filimu yovuta ya amorphous passive yomwe ili ndi trivalent ndi hexavalent chromiumpamwamba pa aluminiyumu.

Kufunika Kwambiri kwa Chithandizo:

1. Imakulitsa Kukhazikika kwa Adhesive Bond: Kuphimba kutembenuka kumapereka malo ogwira ntchito olemera -OH magulu, kupanga zomangira zolimba zamakemikolo ndikulumikizana mwakuthupi ndi zomatira monga epoxy kapena phenolic resins.
2. Kupititsa patsogolo Kukaniza kwa Kuwonongeka kwa Substrate: Filimuyi imagwira ntchito ngati chotchinga, kuchedwetsa bwino kuwonongeka kwa electrochemical kwa gawo lapansi la aluminiyamu m'malo ovuta (chinyezi, Tsegulani mchere), kupewa zomatira kulephera chifukwa cha dzimbiri gawo lapansi.
3. Imatsimikizira Mawindo a Njira: Kukhazikika kwapamwamba kumatsimikizira kusasinthika pakusindikiza kwa zomatira ndi njira zopangira lamination, zomwe ndizofunikira kuti mupeze mizere yomatira yofananira komanso mphamvu yayikulu ya node.
