Extrusion yog txhais tau tias tsim ib qho profile. Ua ntej, raws li Tshooj Cai tsim khoom siv, tsim cov pwm, siv cov tshuab ua hluav taws xob yuav tsum rhuab hloov cov pas nrig ntawm cov pwm extrusion tsim. Feem ntau siv qib 6063 txhuam, nyob rau hauv lub extrusion, kuj siv cov txheej txheem cua txias thiab quenching tom qab txheej txheem kom tiav cov kev kho mob kub kom zoo. Cov kawm sib txawv ntawm kev kho kom sov, nws txoj kev kho kom sov yog txawv.
Kom pleev xim (txheej txheem ntawm oxidation nyob rau hauv thawj qhov chaw)
Oxidation: Extruded aluminium alloy profile, nws cov corrosion deg kuj tsis muaj zog, yuav tsum tau kho los ntawm anodic oxidation ntom kho kom txhim kho txhuas kev txhuam hniav, hnav tsis kam thiab zoo li ntawm lub loog.
Cov txheej txheem tseem ceeb yog:
(1) Cov txheej txheem deg: Siv cov tshuaj los yog kev siv lub cev los ntxuav lub npoo ntawm qhov profile, ua kom pom cov ntshiab matrix, thiaj li yuav tau ua tiav, cov yeeb yaj kiab tso dag hlau. Ib daim iav los yog matte nto kuj tau los ntawm cov khoom siv txhais tau tias.
(2) Anodic oxidation: Lub qhov pretreatment ntawm qhov profile, nyob rau hauv ib lub qee txheej txheem, lub substrate nto anodic oxidation, ib txheej ntawm ntom, ntxeem tau, muaj zog adsorption $ zaj duab xis txheej.
(3) Sealing: qhov pores ntawm ntxeem tau oxide films uas ua los ntawm anodic oxidation raug kaw, uas ua rau oxidation zaj duab xis anti-pollution, corrosion resistant thiab hnav tsis zoo enhanced. Cov yeeb yaj duab oxide yog tsis muaj xim thiab pob tshab, siv cov adsorption zog ntawm cov membrane ua ntej sealing, thiab tso qee cov hlau ntsev hauv cov yeeb yaj kiab, uas tuaj yeem ua kom pom ntawm qhov profile (silvery dawb) xim, xws li dub, tooj liab, kub thiab Stainless hlau.
