N’chifukwa chiyani mtengo wa ma profiles a aluminiyamu a mafakitale ungakhalebe wokwera?

Mtengo wa ma profiles a aluminiyamu a mafakitale sunasinthe kwenikweni kwa nthawi yayitali. Ngakhale mtengo pa tani imodzi wakonzedwa bwino, opanga omwe amagulitsa ndi mita sadzasintha, ndipo mitengo yawo yakhalabe yokwera. Ndiye chifukwa chake vutoli ndi chiyani?
Chifukwa chomwe mtengo wa ma profiles a aluminiyamu a mafakitale ungakhalire wokwera kwa nthawi yayitali chikugwirizana kwambiri ndi kutukuka kwake. Pakadali pano, zinthu zambiri za chimango zimasinthidwa ndi ma profiles a aluminiyamu a mafakitale, monga chimango cha mzere wosonkhanitsira, chimango cha benchi yogwirira ntchito, chimango choyera cha chipinda, chimango cha zida zosungiramo zinthu, chimango chowonetsera ndi chimango cha sikirini cholumikizira. Pakadali pano, kutukuka kwake sikunatsike, ndipo kugwiritsidwa ntchito kwake kwakula kwambiri. Ngakhale mpikisano wamsika ndi waukulu, kuchuluka kwa kugwiritsidwa ntchito kwake ndi kwakukulu kwambiri, zomwe zimapangitsa kuti mtengo wake ukhale wokwera kwambiri, ndipo n'kovuta kuchepetsa.
Chinthu chachikulu chomwe chimapangitsa kuti ma profiles a aluminiyamu azikwera mtengo chimachokera ku kutchuka kwa ogwiritsa ntchito. Zachidziwikire, ndi mawonekedwe a ma profiles a aluminiyamu a mafakitale omwe angakhutiritse ogwiritsa ntchito ambiri, ndipo izi zidzachitika. Chitsulo chomwe chikubwerachi chomwe chikukula nthawi ino chidzakhala ndi ntchito zambiri mtsogolo, motero chikulosera kuti mtengo wake udzakhala wokwera kwambiri.
