Dab tsi yog cov txheej txheem ntawm kev lag luam aluminium profiles?

Muaj aluminium profiles xa mus rau tag nrho cov txhuas profile tshwj tsis yog cov siv hauv kev tsim cov qhov rooj thiab qhov rais, kab hlau rhuav phab ntsa, sab hauv tsev thiab sab nraum zoov kho kom zoo nkauj thiab kev tsim kho vaj tse. Muaj aluminium profile yog ib hom ntawm txhuas raws li ib qho tseem ceeb ntawm cov ntaub ntawv alloy, aluminium pas nrig los ntawm kub yaj, extrusion kom tau txais cov seem ntawm cov ntaub ntawv sib txawv ntawm txhuas, sib sau ua ke rau hauv cov khoom, raws li qhov sib txawv load-bearing profiles ntawm txawv specifications, thiab coj. txhawb nqa aluminium profile accessories, tsis tas yuav vuam, ntau tus phooj ywg ib puag ncig, thiab khoom siv, disassembly, lub teeb thiab nqa tau yooj yim, txav tau yooj yim heev. Dab tsi yog kev lag luam aluminium profile ntau lawm?
1, casting yog thawj txheej txheem ntawm aluminium ntau lawm
Cov txheej txheem tseem ceeb yog:
(1) Cov khoom xyaw: Raws li cov qib alloy tshwj xeeb uas yuav tsum tau tsim, suav qhov nce ntawm ntau yam khoom siv alloy, thiab tsim nyog phim ntau yam khoom qub.
(2) Smelting: cov ntaub ntawv thawj npaj tau ntxiv rau lub qhov cub melting raws li cov txheej txheem, thiab cov impurities thiab gases nyob rau hauv lub yaj yog zoo tshem tawm los ntawm degassing thiab slagging refining. Muaj aluminium raws li daim ntawv thov, kev lag luam aluminium profiles xa mus rau tag nrho cov txhuas profile tshwj tsis yog rau lub tsev qhov rooj thiab qhov rais, kab hlau rhuav phab ntsa, sab hauv tsev thiab sab nraum zoov kho kom zoo nkauj thiab cov qauv tsim.
(3) Casting: Nyob rau hauv lub premise ntawm ib tug tej yam txheej txheem casting, lub melted kua txhuas yog txias rau hauv ntau yam specifications puag ncig casting rods los ntawm lub tob tob casting system.
2, extrusion: extrusion yog cov txheej txheem ntawm kev sib sau. Muaj aluminium raws li daim ntawv thov, kev lag luam aluminium profiles xa mus rau tag nrho cov txhuas profile tshwj tsis yog rau lub tsev qhov rooj thiab qhov rais, kab hlau rhuav phab ntsa, sab hauv tsev thiab sab nraum zoov kho kom zoo nkauj thiab cov qauv tsim. Ua ntej, raws li seem ntawm cov khoom profile, cov pwm yog tsim thiab tsim, thiab cov rhuab puag ncig casting pas nrig yog extruded los ntawm pwm los ntawm kev lag luam txhuas extrusion tshuab. Feem ntau siv qib 6063 alloy kuj tseem siv cov txheej txheem cua txias quenching thaum lub sij hawm extrusion thiab cov txheej txheem kev laus tom ntej kom ua tiav kev kho cua sov. Cov qib sib txawv ntawm cov cua sov-kho tau muaj zog alloys muaj cov kev kho cua sov sib txawv.
3, xim (ntawm no yog thawj txheej txheem oxidation tseem ceeb)
Oxidation: Lub extruded aluminium alloy profile, nws cov nominal corrosion kuj tsis muaj zog, yuav tsum yog nominal kev kho mob los ntawm anodizing kom cov corrosion kuj, hnav kuj thiab nominal zoo nkauj ntawm txhuas.
Nws cov txheej txheem tseem ceeb yog:
(1) Nominal pretreatment: Lub npe ntawm qhov profile yog ntxuav los ntawm tshuaj lom neeg los yog lub cev txoj kev los nthuav tawm cov matrix qias neeg thiaj li ua kom yooj yim rau kev ua tiav thiab ntom cov khoom siv oxide zaj duab xis. Cov npe tshwj xeeb lossis matte (matte) kuj tuaj yeem tau los ntawm kev siv tshuab.
(2) Anodizing: Tom qab nominal pretreatment ntawm profiles, nyob rau hauv ib tug tej yam txheej txheem premise, lub matrix nominally tsim anodizing, tsim ib tug ntom, ntxeem tau, muaj zog adsorption AL203 zaj duab xis txheej. Muaj aluminium raws li daim ntawv thov, kev lag luam aluminium profiles xa mus rau tag nrho cov txhuas profile tshwj tsis yog rau lub tsev qhov rooj thiab qhov rais, kab hlau rhuav phab ntsa, sab hauv tsev thiab sab nraum zoov kho kom zoo nkauj thiab cov qauv tsim.
(3) Sealing qhov: lub membrane pores ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodic oxidation raug kaw, kom cov oxidation zaj duab xis tiv thaiv kab mob, corrosion kuj thiab hnav kuj muaj zog. oxide zaj duab xis yog tsis muaj xim thiab pob tshab, siv cov khoom muaj zog adsorption ntawm oxide zaj duab xis ua ntej kaw lub qhov, adsorbing thiab tso qee cov hlau ntsev hauv lub qhov zaj duab xis, uas tuaj yeem ua rau lub npe profile qhia ntau xim uas tsis yog cov khoom siv (nyiaj dawb) , xws li: dub, bronze, kub thiab stainless hlau xim.
