Posankha zipangizo zomangira padenga lanu kapena panja, zinthu zopangidwa ndi aluminiyamu ndi zinthu ziwiri zodziwika bwino. Koma ndi iti yabwino kwambiri?

Chingwe chopangidwa ndi ulusi wa matabwa ndi pulasitiki, nthawi zambiri chimakondedwa chifukwa cha kulimba kwake komanso kukongola kwake. Chimawoneka ngati matabwa popanda kufunikira kochisamalira, zomwe zimapangitsa kuti chisamavunde, chisweke, komanso chizitha kutha. Kuphatikiza apo, zingwe zopangidwa ndi ulusi zimapezeka mumitundu yosiyanasiyana, zomwe zimapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito popanga zinthu zosiyanasiyana.

Mosiyana ndi zimenezi, aluminiyamu imadziwika chifukwa cha kulimba kwake komanso kupepuka kwake. Imalimbana ndi dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera madera a m'mphepete mwa nyanja okhala ndi mpweya wamchere. Aluminiyamu imafunanso kusamalidwa pang'ono, imafunika kutsukidwa nthawi ndi nthawi kuti isunge mawonekedwe ake okongola komanso amakono. Komabe, sizingafanane ndi mawonekedwe ofunda komanso achilengedwe a composite.

Ponena za kulimba, chitoliro cha composite nthawi zambiri chimakhala ndi moyo wautali, pomwe aluminiyamu imapambana kwambiri m'malo omwe mphepo imawomba chifukwa cha mphamvu zake zapamwamba. Kusankha kwabwino kwambiri kumadalira zomwe mukufuna - kuphatikiza chifukwa cha kukongola kwake komanso ubwino wake, kapena aluminiyamu chifukwa cha mphamvu zake komanso kusamalika mosavuta.

Ngati mukufuna njira yolimba komanso yokongola yopangira njanji, zipangizo zonse ziwiri zili ndi ubwino wake, koma zosakaniza zimatha kupambana aluminiyamu pankhani ya magwiridwe antchito onse komanso kusinthasintha.
