Anọ isi ọrụ nke pretreatment na aluminum alloy elu finishing

Mgbe profaịlụ extrusion aluminum na-enweta pretreatment na saịtị n'oge mmepụta, ihe mgbochi corrosion na ihe ịchọ mma nke elu aluminom nwere ike imeziwanye nke ọma.

Ọrụ 1: Site na ọgwụgwọ roughening elu dị ka sandblasting na kemịkalụ etching, pretreatment na-emepụta obere ihe siri ike Ọdịdị n'elu na-etolite n'ibu anchoring saịtị maka ntụ ntụ mkpuchi. Ọdịiche dị n'elu kwesịrị ekwesị nwere ike ịkwalite mmetụta mgbakasị n'ibu nke mkpuchi.

Ọrụ 2: Site na ọgwụgwọ ịgbalite elu elu dị ka pickling na alkaline etching, pretreatment na-ewepụ oyi akwa inert oxide n'elu, na-ekpughe elu igwe ọhụrụ ma na-emezi ọrụ kemịkalụ elu. Ngwọta mkpuchi mgbanwe kemịkalụ na-etolite ihe nkiri ntụgharị na-emeghachi omume n'elu iji nye saịtị njikọ kemịkalụ maka mkpuchi. Maka profaịlụ aluminom ejiri na windo na ọnụ ụzọ profaịlụ aluminom dị elu, enwere ike ịchọ usoro ọgwụgwọ elu abụọ ma ọ bụ atọ na-aga n'ihu.

Ọrụ 3: Pretreatment na-emetụta wettability na interfacial bonding ike n'etiti mkpuchi na mkpụrụ, na budata mma wettability nke aluminum profaịlụ elu.

Ọrụ 4: Ihe nkiri ntughari ma ọ bụ ọkwa ndị ọzọ a na-emeso n'elu site na pretreatment na-arụ ọrụ dị ka oyi akwa mgbanwe ihu, nke na-ebelata nrụgide nrụgide n'etiti mkpụrụ na mkpuchi ma na-abawanye ike njikọ ihu.
