Inzira Zihariye za Polyester (PE) Gusaba Porogaramu kuri ACM kubikoresho byo murugo

Polyester (PE) itwikiriye ibikoresho-byo mu rwego rwa Aluminiyumu Ibikoresho (ACM) bikoreshwa ku mpapuro za aluminiyumu mbere (mbere yo guhuza ibice), ukoresheje umurongo uhoraho wo gutwikira. Iyi gahunda yo mu rwego rwinganda yateguwe kugirango ihuze ibyifuzo bikenerwa n’ibikoresho byo mu rugo - kwemeza uburinganire buhanitse, gukomera cyane kuri aluminiyumu, no guhinduka gukomeye nyuma yo gushyirwaho kashe, kunama, no gukora inzira. Imikorere ihamye ya ACM isize kandi iremeza ko irwanya igihe kirekire ibidukikije byo murugo (ubuhehere, umwotsi wamavuta, ibikoresho byogusukura) kandi bikomeza kugaragara mubuzima bwumurimo wibikoresho. Hasi nuburyo bwuzuye, burambuye bwa tekiniki:

Aluminium Substrate Uncoiling & Surface Gutegura

Icyiciro cyo gutegura ubuso ni ingenzi cyane kugirango habeho gufatira hamwe no kurwanya ruswa - ibyanduye byose bisigaye cyangwa okiside bizagira ingaruka ku bwiza bwa nyuma bwibikoresho. Iki cyiciro gikurikira neza, cyikora:

Gupfundikanya Igiceri cya Aluminium
