1. Melting thiab casting yog thawj txheej txheem hauv 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 cov nyiaj ntxiv ntawm ntau yam khoom siv hlau thiab sib xyaw ua ke ntau yam khoom siv raw.
(2) Smelting: Ntxiv cov khoom nyoos npaj rau hauv lub qhov cub smelting rau melting raws li cov txheej txheem yuav tsum tau, thiab tshem tawm impurities thiab gases nyob rau hauv lub yaj los ntawm degassing thiab slag tshem tawm refining txoj kev.
(3) Casting: Lub smelted aluminium kua yog txias thiab nrum rau hauv cov cam khwb cia rods ntawm ntau yam specifications los ntawm qhov sib sib zog nqus zoo casting system nyob rau hauv tej yam txheej txheem casting.
2. Extrusion: Extrusion yog ib txoj kev ntawm kev tsim profile. Ua ntej, cov pwm yog tsim thiab tsim raws li tus ntoo khaub lig-section ntawm cov khoom profile, thiab cov rhuab puag ncig cam khwb cia qws yog extruded los ntawm cov pwm siv ib tug extruder. Cov feem ntau siv qib 6063 alloy kuj tseem siv cov txheej txheem cua txias quenching thiab cov txheej txheem kev laus tom ntej thaum extrusion kom ua tiav kev kho cua sov ntxiv. Cov qib sib txawv ntawm cov cua sov-kho tau muaj zog alloys muaj cov txheej txheem kho cua sov sib txawv.
3. Xim xim (ntawm no peb yuav tsom mus rau cov txheej txheem oxidation)
Oxidation: Qhov saum npoo ntawm extruded aluminium alloy profiles tsis heev corrosion-resistant. Nws yuav tsum tau kho deg los ntawm anodizing kom muaj kev tiv thaiv corrosion, hnav tsis kam thiab zoo li ntawm aluminium.
Nws cov txheej txheem tseem ceeb yog:
(1) Nto pretreatment: Siv tshuaj los yog lub cev txoj kev los ntxuav qhov chaw ntawm qhov profile kom nthuav tawm cov ntshiab matrix, thiaj li yuav tau ib tug tiav thiab ntom oxide zaj duab xis. Daim iav los yog matte (matte) nto kuj tuaj yeem tau los ntawm kev siv tshuab.
(2) Anodizing: Hauv qee cov txheej txheem txheej txheem, qhov saum npoo ntawm qhov chaw-pretreated profile yuav raug anodized los tsim cov ntom ntom, ntxeem tau, muaj zog adsorption AL203 zaj duab xis txheej.
(3) Sealing: Seal lub qhov hws ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodization los txhim khu kev tiv thaiv kev ua qias tuaj, corrosion kuj thiab hnav tsis kam ntawm oxide zaj duab xis. oxide zaj duab xis yog xim tsis muaj xim thiab pob tshab. Los ntawm kev siv lub zog adsorption ntawm oxide zaj duab xis ua ntej sealing, qee cov hlau ntsev yog adsorbed thiab tso rau hauv cov yeeb yaj kiab qhov pores, uas tuaj yeem ua rau saum npoo ntawm qhov profile qhia ntau xim uas tsis yog cov xim qub (nyiaj dawb), xws li: dub, bronze, Golden daj thiab stainless hlau xim, thiab lwm yam.
