Pamakina a mafakitale ndi uinjiniya wamagalimoto, kufunikira kwa zida zolimba zomwe zimawonetsetsa kuti magwiridwe antchito abwino sizingapitiritsidwe. Zina mwa zigawo izi,zophimba za aluminiyumu aloyi kuponyerazapezeka ngati yankho lofunikira komanso losunthika. Ndi mphamvu zake zapadera, mawonekedwe opepuka, komanso zinthu zolimbana ndi dzimbiri, zophimbazi zimagwira ntchito yofunika kwambiri poteteza makina ofunikira ndikuwonjezera magwiridwe antchito awo onse. Cholemba ichi chabulogu chimayang'ana tanthauzo la zovundikira zotayira za aluminiyamu, kuwunikira mbali zake zofunika, zopindulitsa, ndi ntchito.
1. Chitetezo Champhamvu:
Zophimba zopangira aluminium alloy zidapangidwa makamaka kuti ziteteze ndikutchinjiriza zinthu zofunikira kuzinthu zosiyanasiyana zakunja, kuphatikiza fumbi, zinyalala, chinyezi, komanso nyengo yoyipa. Pokhala ngati chotchinga choteteza, zophimbazi zimalepheretsa zinthu zosafunikira kulowa ndikuwononga makina, kuchepetsa chiopsezo chosokonekera kapena kuwonongeka. Kukhazikika kwawo komanso kukana kwamphamvu kumatsimikiziranso kutalika kwa zigawo zophimbidwa.
2. Wopepuka komanso Wosiyanasiyana:
Poyerekeza ndi zida zina monga chitsulo kapena chitsulo, zotayira za aluminiyamu zimawonetsa zinthu zopepuka kwambiri, zomwe zimawapangitsa kukhala abwino popangira zovundikira. Kulemera kocheperako kumakhala kopindulitsa pankhani ya mayendedwe, kuwongolera, komanso kumasuka kwathunthu. Chikhalidwe chopepukachi chimathandizira kusinthasintha kowonjezereka popanga zida zovuta, kuonetsetsa kuti zikuyenda bwino komanso magwiridwe antchito abwino. Kuphatikiza apo, ma aloyi a aluminiyamu amatha kuponyedwa m'mawonekedwe osiyanasiyana, kulola kusinthika kwa zovundikira pazofunikira zinazake.
3. Thermal Conductivity:
Ubwino winanso wa zovundikira zotayira za aluminiyamu ndi matenthedwe awo abwino kwambiri. Ma aluminiyamu aloyi ali ndi mphamvu yotha kutentha kwambiri, yomwe imathandizira kuyendetsa bwino kutentha kopangidwa ndi makina otsekedwa. Khalidweli ndi lofunika kwambiri pazantchito zomwe kuwongolera kutentha kuli kofunika kwambiri kuti zisungidwe bwino kapena kupewa kutenthedwa. Pochotsa bwino kutentha, zovundikira zotayira za aluminiyamu zimathandizira kukulitsa moyo wa zida zodziwikiratu ndikuwonjezera mphamvu zake zonse.
4. Kukanika kwa Corrosion:
Kuphatikiza pa kulimba kwawo, zotayira za aluminiyamu zimadziwika chifukwa cha kukana kwapadera kwa dzimbiri. Katunduyu amawapangitsa kukhala oyenera kuponyera zophimba zomwe zimakumana ndi zinthu zosiyanasiyana zachilengedwe, monga chinyezi, mankhwala, kapena madzi amchere. Kukana kwa dzimbiri sikumangoteteza makina komanso kumachepetsa ndalama zokonzera zomwe zimagwirizanitsidwa ndi kukonzanso kapena kusinthidwa chifukwa cha kuwonongeka kwa dzimbiri.
5. Ntchito Zosiyanasiyana:
Zophimba za Aluminium alloy castingkupeza ntchito zambiri m'mafakitale osiyanasiyana. Amagwiritsidwa ntchito kwambiri popanga magalimoto popanga zovundikira zama injini, ma gearbox, ndi zovundikira zotumizira. M'makampani azamlengalenga, amakhala ngati nyumba zodzitchinjiriza pazofunikira zamagetsi zamagetsi kapena ma hydraulic system. Kuphatikiza apo, amagwiritsidwa ntchito kwambiri popanga makina olemera, zida zopangira magetsi, komanso zida zamagetsi zamagetsi, chifukwa cha kusinthasintha kwawo komanso mapindu omwe amapereka.
Zovundikira zopangira ma aluminiyamu zakhala gawo lofunikira pamakina amakono chifukwa cha kulimba kwawo, kapangidwe kake kopepuka, kukhathamiritsa kwamafuta, komanso kukana dzimbiri. Zophimba izi sizimangoteteza zinthu zofunika zokha, komanso zimawonjezera magwiridwe antchito ndikuwonetsetsa kuti zida zakhala zikugwira ntchito nthawi yayitali. Pomwe ukadaulo ukupita patsogolo, kufunikira kwa zovundikira zopangira ma aluminiyamu akuyembekezeredwa kukula, ndikusamalira mafakitale osiyanasiyana omwe amadalira makina amphamvu komanso ogwira mtima.
