Aluminium profile tsim txheej txheem

Aluminium profile ntau lawm suav nrog peb txheej txheem: melting thiab casting, extrusion thiab deg kho (xim feem ntau suav nrog oxidation, electrophoretic txheej, fluorocarbon spraying, hmoov txau, ntoo grain hloov luam ntawv, thiab lwm yam).

1. Melting thiab casting yog thawj txheej txheem ntawm txhuas profile ntau lawm. Cov txheej txheem tseem ceeb yog:

(1) Cov khoom xyaw: xam qhov sib ntxiv ntawm ntau yam khoom siv alloy raws li cov hom alloy tshwj xeeb yuav tsum tau tsim, thiab tsim nyog phim 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 zoo tshem tawm lwm yam slag thiab roj nyob rau hauv lub yaj los ntawm kev degassing thiab slag refining.
(3) Casting: molten aluminium yog txias thiab cam khwb cia rau hauv round cam khwb cia rods ntawm ntau yam specifications los ntawm sib sib zog nqus casting system nyob rau hauv tej yam txheej txheem casting.

2. Extrusion:extrusion yog cov txheej txheem ntawm txhuas profile. Ua ntej, qhov tuag yog tsim thiab tsim raws li seem ntawm cov khoom profile, thiab cov rhuab puag ncig cam khwb cia yog extruded los ntawm cov tuag los ntawm extruder (nyob rau hauv cov txheej txheem no, tuag, extruder thiab round cam khwb cia qws yuav tsum tau rhuab). 6063-T5 aluminium alloy feem ntau siv los ntawm Hongfa nonferrous hlau kuj muaj 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 kom muaj zog alloys muaj cov txheej txheem kho cua sov sib txawv.

3. Kev kho deg
Oxidation: cov extruded aluminium alloy profile feem ntau hu ua cov khoom siv hauv paus, thiab nws qhov kev tiv thaiv corrosion tsis muaj zog. Kev kho saum npoo yuav tsum tau nqa tawm los ntawm anodic oxidation kom muaj kev tiv thaiv corrosion, hnav tsis kam thiab zoo nkauj ntawm txhuas. Cov txheej txheem tseem ceeb yog:
(1) Deg pretreatment: ntxuav lub profile nto los ntawm tshuaj lom neeg los yog lub cev txoj kev los nthuav tawm cov ntshiab matrix, thiaj li yuav tau ib tug tiav thiab ntom khoom oxide zaj duab xis. Daim iav lossis matte (Matt) qhov chaw kuj tuaj yeem tau los ntawm kev siv tshuab.
(2) Anodizing: rau saum npoo pretreated profile, nyob rau hauv tej yam txheej txheem, lub substrate nto yuav anodized los ua ib tug ntom, ntxeem tau thiab muaj zog adsorption alumina zaj duab xis.
(3) Pore sealing: kaw lub qhov hws ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodic oxidation, txhawm rau txhim kho cov pa phem, tiv thaiv corrosion thiab hnav tsis kam ntawm oxide zaj duab xis. Cov oxide zaj duab xis tsis muaj xim thiab pob tshab. Los ntawm kev siv lub zog adsorption ntawm oxide zaj duab xis ua ntej kaw lub qhov, qee cov hlau ntsev yog adsorbed thiab tso rau hauv lub qhov zaj duab xis, uas tuaj yeem ua rau cov duab profile qhia ntau xim uas tsis yog xim ntuj (nyiaj dawb), xws li dub. , bronze, golden yellow thiab stainless hlau.

Oxidation kab

Lub kaw lus aluminium profile tuaj yeem ntim tau tom qab ntxuav thiab ziab. Aluminium profiles feem ntau ntim nrog cov ntaub tsis-woven + kraft ntawv. Tom qab lub ntim tiav lawm, nws yuav tsum tau saws rau hauv ib qho ntev raws li tus neeg siv khoom xav tau ua ntej nws tuaj yeem muab tso rau hauv qhov chaw cia. Lub sawing ntev ntawm kev lag luam txhuas profile yog 6.02M.
