Profaịlụ aluminom nwere ngwa ngwa dị iche iche, ma n'ihi ihe mejupụtara ya dị iche iche, ọ ga-esi ike ịchịkwa mmecha na usoro nke extrusion, si otú a ga-eme ka dulness, site na nyocha ihe na-egbuke egbuke nke ngwaahịa profaịlụ aluminum nwere ike imeziwanye na atọ. akụkụ:
1. Alloy mejupụtara ruru nke ihe onwunwe: dịkwuo ọdịnaya nke chemical ọcha ọla kọpa na magnesium, na-atụ aro ruru bụ: Si0.55-0.65, Fe <0.17, Cu0.3-0.35, Mg1.0-1.1.
2. Na-achịkwa usoro nkwụsịtụ ma melite okpomọkụ nke ihe nkwụsị nke profaịlụ aluminom.Ọ na-atụ aro na okpomọkụ nke aluminum mkpanaka na-510-530 ℃ na okpomọkụ nke tinyekwa 530-550 ℃.
3. Gbanwee pretreatment usoro nke dyeing anodic oxidation, naanị pickling mmanụ maka aluminum profaịlụ, ọ bụghị alkali corrosion.
Okwu:
Aluminom profaịlụ mkpuchi ugbu a n'ozuzu uzuzu mkpuchi na agba mkpuchi.
Maka mmetụta ọkụ na nke na-egbuke egbuke:
1. Jiri ezigbo egbe ịgba, ka ọnụ ọgụgụ nke ntụ ntụ spraying muzzle, nke ukwuu na foogu ka mma (uniform ejection mmetụta)
2. High gloss (gloss 95 na n'elu) ntụ ntụ (nhọrọ agba) ma ọ bụ agba na ezigbo fluorocarbon agba.
