Lub hauv paus ntsiab lus ua haujlwm ntawm txheej txheej aluminium coil feem ntau suav nrog ob kauj ruam: pretreatment ntawm aluminium coil thiab txheej ci. cov
Pretreatment ntawm aluminium coil:
Ua ntej, ntxuav cov roj lubricating, cov roj los tiv thaiv oxidation thiab ntau yam av uas txuas rau saum npoo ntawm aluminium coil thaum lub sij hawm dov, thiab tshem tawm cov nag lossis daus ntawm impurities xws li silicon, magnesium thiab tooj liab nyob rau saum npoo ntawm txhuas. cov
Tom qab ntawd, ntxiv qee cov khoom siv tshuaj lom neeg los kho cov aluminium coil los tsim cov yeeb yaj kiab honeycomb oxide tuab ntawm nws qhov chaw. Lub hom phiaj ntawm cov kauj ruam no yog ua kom cov xim thiab aluminium coil nruj nreem sib xyaw ua ke thaum lub txhuas coil yog coated, thiab muaj adhesion zoo. cov
Txheej ci:
Aluminium coil tom qab txheej txheej tshuaj raug xa mus rau txheej txheej thiab pleev xim nrog cov xim teev los ntawm tus neeg siv khoom. cov
Nyob rau hauv thawj theem, precision txheej yog nqa tawm nyob rau hauv lub kaw thiab tsis muaj plua plav lub xeev siv ib tug precision peb-yob rov qab cov menyuam txheej tshuab los tswj cov txheej thickness thiab zoo li zoo. cov
Nyob rau theem ob, cov txheej txheem ci tau muab faib ua plaub qhov chaw rauv, nrog rau qhov sib txawv ntawm qhov kub thiab txias tau teem rau ci cov xim txhuas coil. Los ntawm kev kub-kub ci, cov xim molecules yog txuas thiab solidified, yog li ntawd cov kuab tshuaj kuj, hardness, yooj thiab huab cua tsis kam ntawm txheej yog tag nrho cov nyob rau hauv lub zoo tshaj plaws lub xeev. cov
Los ntawm ob kauj ruam no, cov coated aluminium coil muaj gloss zoo, adhesion thiab corrosion kuj 1. cov
