Izinqubo ezijwayelekile zokwelashwa kwe-aluminium alloy surface -Ingxenye Yokuqala

Ukwelashwa okuhlukile okungaphezulu kungasetshenziswa kuphrofayili ye-aluminium, futhi inqubo ngayinye yokwelapha inezinzuzo zayo ezihlukile, ukungalungi kanye nezimo zohlelo lokusebenza.

Okokuqala, ubuchwepheshe bokwelashwa kwe-mechanical surface. I-Sandblasting: Isimiso saso esiyinhloko ukuthi izinhlayiya ze-abrasive zesivinini esiphezulu zithinta futhi zicindezele ubuso be-aluminium extrusions ukuze zenze ukuguqulwa kwepulasitiki, kwakha ungqimba lwe-pressive compressive stress.

Okulandelayo, ukugaya nokupholisha. I-Mechanical friction isusa ama-protrusions angaphezulu ukuze kuncishiswe ama-rough.Ukugaya kuyinqubo yokusika kancane, kuyilapho ukupholishwa kuwumsebenzi omuhle wokuqeda.

Okwesibili, ubuchwepheshe bokwelashwa kwamakhemikhali.

I-Chemical Conversion Coating: Ifilimu yekhemikhali eqhubekayo futhi ezinzile yakha lapho indawo yensimbi isabela ngamakhemikhali nesixazululo sokwelapha. Ithuthukisa ukubukeka kokuhlobisa kwephrofayili ye-aluminium extrusion futhi isetshenziswa kakhulu kumaphrofayili e-aluminium efasiteleni nomnyango.

Okulandelayo, ukukhetha: I-Acid ihlangana ne-aluminium extrusion ukuze isuse isikali se-oxide. Ukuhlanzwa kwe-alkaline: I-alkali icolisa amafutha ngaphezulu ukuze asuse amafutha.
