Aluminium can ndi chidebe chojambulira wamba m'moyo wathu watsiku ndi tsiku,
amagwiritsidwa ntchito kwambiri popakira zakumwa ndi zakudya zosiyanasiyana. Anthu ambiri amatha kuona kugunda kowoneka bwino m'mphepete mwa kamwa lachitsulo mukamagwiritsa ntchito aluminiyamu , koma ndi ochepa omwe amadziwa sayansi kumbuyo ndi gawo la kapangidwe kameneka. Ndikufunseni zomwe zili mkati mwa bwalo lophulikalo mozungulira m'mphepete mwa chitini cha aluminiyamu, ndipo mwina munganene kuti, 'Ndikutsimikiza kuti ndi bobo.' Koma sichoncho!
Mu 1810, kuti apititse patsogolo kusunga chakudya, Peter Durand wa ku England anatulukira chitini choyamba chachitsulo padziko lapansi. Komabe, panadutsa zaka zoposa 100 pamene zosavuta zotsegula za aluminiyamuanatulukira njira ina. Mu 1959, Amereka kudzera luso, ntchito akhoza kuphimba zipangizo zopangidwa rippers, ndiyeno anapereka mphete Chikoka ndi riveting, ndi kugoletsa zolondola, bwinobwino kupanga wathunthu zitsulo zotayidwa mosavuta kutsegula chivundikiro . Izi zatsopano zidalimbikitsa kwambiri kupita patsogolo kwaukadaulo wazitsulo zazitsulo. Pofika m'ma 1970 ndi 1980, kupanga zitini zotayidwa pang'onopang'ono kunafalikira ku Japan, South Korea ndi madera ena.
ku China, kumayambiriro kwa zaka za m'ma 1980, Qingdao Brewery anayambitsa bwino kusindikizidwa zonse zotayidwa 2 zidutswa zitini ku Japan kwa nthawi yoyamba kuti azolowere ndi ma CD zosowa za katundu kunja, amene chizindikiro chiyambi cha ntchito lonse la zitini ku China. Zitini zikhoza kugawidwa m'magulu awiri akuluakulu malinga ndi zipangizo: imodzi imapangidwa ndi tinplate, monga Lulu Almond Renlu ndi ma CD a JDB; Zinazo zimapangidwa ndi aluminiyamu, monga zamzitini Coca Cola ndi mowa, zakumwa za carbonated ndi zina zotero.
Mapangidwe a zitini zachitsulo akhoza kugawidwa mowonjezereka mu zitini ziwiri ndi zitini zitatu . Chitini cha zigawo zitatu chili ndi magawo atatu: chitini, pansi ndi chitini. Thupi la chitini limakhala ndi mfundo, ndipo thupi la chitini limalumikizidwa ndi chivundikiro cha chitini ndipo chitinicho chimakhala pansi pamphepete. Zitini ziwirizi zimapangidwa ndi magawo awiri: chitini chophimba ndi chosindikizidwa chopanda msoko ndi pansi. Thupi la chitini ndi chivundikirocho chimapangidwa kukhala chimodzi mwakugudubuza.
Ndipotu, thupi la Aluminiyamu akhoza kupangidwa ndi stamping mapepala aluminiyamu. Makulidwe a pepala la aluminiyumu iyi ndi pafupifupi mamilimita 0.3. Panthawi yopondaponda, pepala la aluminiyamu limayikidwa pa chida chotchedwa stretch die. Chikhomero cha cylindrical kenako chimakanikizira pansi pa pepala kuchokera pamwamba, ndikulisandutsa mu silinda yayifupi yooneka ngati phulusa. Njira imeneyi imatchedwa stamping.
Komabe, pakangodutsa chidindo chimodzi chokha, silinda yopangidwa ndi pepala la aluminiyamu ikadali yotakata komanso yokhuthala, yomwe siinafikebe mawonekedwe a aluminiyamu yomaliza, kotero kuti masitampu angapo akufunika. Kupondaponda kulikonse kumapangitsa pepala la aluminiyamu kukhala locheperako komanso locheperako mu radius, pomwe likukulirakulira. Pambuyo pa makina osindikizira angapo otere, pepala loyambirira la aluminiyumu lozungulira pang'onopang'ono limapanga ndondomeko ya aluminiyumu.
Panthawiyi, pali masitepe awiri okha omwe atsala kuti apange aluminiyamu akhoza : imodzi ndiyo kupanga kuvutika maganizo pansi pa aluminiyumu akhoza, ndipo ina ndiyo kusindikiza. Kupanga kupsinjika kwapansi kumangofunika kugwiritsa ntchito chida chofanana ndi dome, chofanana ndi kupondaponda pomwe aluminiyamu imatha kukanikizidwa pamwamba pa theka la kuzungulira kuti apange mawonekedwe okhumudwa. Kapangidwe kameneka kamafanana ndi mlatho wa arch ndipo amatha kupirira kupsinjika kwakukulu. Zonsezi pamodzi zimatenga gawo limodzi mwa magawo asanu ndi awiri okha pa sekondi imodzi.
Pambuyo pokonza pamwamba pa chitini cha aluminiyamu, choyikapo chakunja chikhoza kupopera. Panthawi imodzimodziyo, mkati mwa aluminiyumu iyeneranso kutsekedwa kuti muteteze zakumwa za acidic kuti zisagwirizane ndi aluminiyumu komanso kupewa kudya kwambiri kwa aluminiyumu komwe kumakhudza thanzi la mitsempha. Kenako, khosi la chitini liyenera kukokedwa kuti likhale lopyapyala kuti mupewe makwinya mu chitini chopyapyala chokhala ndi mipanda ya aluminiyamu. Pomaliza, gawo lofunikira kwambiri ndikusindikiza chitoliro cha aluminiyamu, ndichifukwa chake pamakhala phokoso lozungulira m'mphepete mwa kamwa la aluminiyamu.
Kodi kugunda m'mphepete mwa chitini cha aluminiyamu ndi chiyani?
Kuti soda asatayike, timasindikiza pamwamba pa chitini cha aluminiyamu. Panthawiyi, ndi nthawi ya protagonist wathu lero - mphete ya ng'oma kuti atengepo mbali. Njira yosindikizira zitini za aluminiyamu iyi imatchedwanso kusindikiza pawiri, ndiye kusindikiza pawiri ndi chiyani?
Monga momwe chithunzi chili pansipa, chofiira chimayimira pepala la aluminiyamu pa chivindikiro cha aluminiyamu, ndipo buluu imayimira pepala la aluminiyamu pa thupi la aluminiyamu. Chivundikiro cha thanki ndi m'mphepete mwa thanki zidzamangidwa mwamphamvu pansi pa mphamvu ya makina, ndipo izi zidzapanga gawo loyamba la nthiti. Kenaka, pogwiritsira ntchito kukakamiza kachiwiri, gawo lachiwiri la zopota zimapangidwira, zomwe zimakhala mkati mwa gawo loyamba la zopota. Mwa njira iyi, zigawo ziwiri za zisindikizo zimapangidwira pakati pa chivindikiro ndi thupi la thanki, zomwe zimawoneka ngati masika.
Komabe, kusindikiza pawiri palokha sangathe kudzipatula kwathunthu mkati ndi kunja kwa akhoza, mu wosanjikiza wa kusindikiza pawiri mkati mwa kusiyana wodzazidwa ndi madzi sealant. Amagwira ntchito ngati guluu wapadera yemwe amagwirizanitsa mapepala awiri a aluminiyumu pamodzi mwamphamvu ndikuletsa soda kuti asatuluke. Kuphatikiza apo, imalepheretsa dothi kulowa mkati mwa aluminiyamu. Mapangidwe a chosindikizira nthawi zambiri amakhala osakaniza a latex, labala kapena utomoni, ndi kusungunuka mu zosungunulira zamafuta. Ndiye ndani angaganize kuti madzi amafuta angakulungidwe pamphepete mwa chitini cha aluminiyamu?
