Ua ntej peb tau hais txog peb txhuas txheej txheem txheej txheem txheej txheem, lub sijhawm no weihua (txhuas extrusion tuam txhab) xav qhia luv luv rau koj li cas peb siv cov kev lag luam aluminium extrusion khoom tsim tawm.

1. Melting casting

(Melting casting yog thawj txheej txheem ntawm txhuas ntau lawm)

(1) Cov khoom xyaw:

Raws li qhov tshwj xeeb ntawm cov khoom lag luam alloy uas yuav tsim tawm, laij cov nqi sib ntxiv ntawm ntau cov khoom siv hauv cov thooj voos, thiab tsim nyog phim ntau cov ntaub ntawv raw.

(2) Smelting:

Cov khoom siv sib xyaw ua ke yog melted rau hauv lub tshuab ua kom sov, raws li cov txheej txheem thev naus laus zis, thiab cov impurities thiab roj cua hauv cov yaj tau muab tshem tawm tau zoo los ntawm txoj kev degassing thiab slag tshem tawm cov dej ua kom zoo.

(3) Cov Ntawv:

Tus hlau molten yog txias thiab pov rau hauv cov kab puag ncig ntawm ntau cov kev qhia tshwj xeeb los ntawm kev sib sib zog nqus zoo casting system nyob rau hauv qee yam kev ua haujlwm casting.

2. Extrusion:

Extrusion yog txhais tau tias kev ua cov xa tawm profiles.Thaum thawj, raws li cov khoom lag luam ntu tsim qauv, tsim khoom lag luam pwm, siv lub tshuab txuas ntxiv yuav rhaub zoo puag ncig cam cam extrusion daim ntawv ua pwm.

Cov feem ntau siv 6063 alloy yog extruded nrog cov txheej txheem huab cua txias ua kom tiav thiab cov txheej txheem kev laus tsim kom tiav cov kev kho cua sov.Qhov kev kho cua sov ntawm cov cua kub-kho tau alloy ntawm cov qib sib txawv yog txawv.

3. Cov xim

(Ntawm no peb tsuas yog tham txog oxidation), extruded aluminium alloy profile, nws qhov chaw tiv thaiv corrosion tsis muaj zog, yuav tsum tau anodized rau kev kho saum npoo kom nce qhov corrosion corrosion ntawm aluminium, hnav tsis kam thiab zoo li qib zoo nkauj.

Cov txheej txheem loj yog raws li nram no:

(1) Nto pretreatment:

Kev siv tshuaj los yog kev siv lub cev yog siv los ntxuav qhov saum npoo ntawm qhov profile kom nthuav tawm cov ntshiab hauv qab, kom thiaj li ua tiav tiav thiab ntuag cov tshuaj oxide zaj duab xis.

(2) Anodic oxidation:

Tom qab cov txheej txheem ua ntej saum npoo av, nyob rau hauv qee yam txheej txheem thev naus laus zis, anodic oxidation tshwm sim rau ntawm cov txheej txheej txheej qis, ua rau muaj qhov ntom, ntxeem thiab muaj zog adsorption AL2O3 zaj duab xis txheej.

(3) Lub qhov khi:

Lub qhov hws ntawm cov dej ua ntu oxide zaj duab xis tsim tom qab anodic oxidation raug kaw los txhim kho kev tiv thaiv kev ua qias tuaj, tiv thaiv corrosion thiab hnav tsis kam ntawm oxide zaj duab xis.Oxidation zaj duab xis tsis muaj xim thiab pob tshab, kev siv cov muaj zog adsorption ntawm oxidation zaj duab xis ua ntej sib khi, hauv zaj duab xis lub qhov adsorption deposition ntawm qee cov hlau ntsev, tuaj yeem ua rau cov duab profile qhia ntuj (nyiaj dawb) lwm yam ntau dua li xim, xws li: dub, tooj, kub thiab stainless hlau xim.
