Why ua cov aluminium alloyy yuav rov qab muaj pwm thiab qhov chaw tom qab khaws cia rau lub sijhawm?

Qhov teeb meem no tau ntsib los ntawm ntau tus neeg siv khoom, thiab nws yog ib qho yooj yim rau cov neeg siv khoom tsis paub dhau los ntsib cov xwm txheej zoo li no. Txhawm rau zam cov teeb meem zoo li no, nws tsuas yog yuav tsum tau ua tib zoo saib xyuas peb lub ntsiab lus hauv qab no:

1. Qhov chaw uas cov ntaub ntawv muab tso rau yuav tsum tsis txhob dampness. Qee cov neeg muas zaub yuav cov ntaub ntawv thiab muab tso rau hauv cov hlau yooj yim, uas tuaj yeem xau los nag lossis muaj cov plag tsev ntub dej. Yog tias sab laug rau lub sijhawm ntev, cov pwm thiab oxidation tuaj yeem tsim.

2. Rau cov neeg muas zaub ntawm kev ua hom, xws li pwm ua, machining, txiav, thiab lwm yam, yuav tsum xyuam xim rau seb puas muaj residual tso cov neeg ua hauj, txiav kua, saponification kua, thiab lwm yam. Cov tshuaj corrosive no yuav tsum tau muab ntxuav kom raws sijhawm. Tom qab cov khoom tiav lawm, nws yuav tsum kujkhaws cia kom raug. Polishing wax, roj stains, thiab lwm yam siv rau polishing yuav tsum tau ntxuav. Yog tias lawv tsis kho kom zoo, nws kuj yog ib qho yooj yim los ua cov pob daj ntawm cov khoom siv tom qab anodizing.

3. Cov tshuaj ntxuav tsis raug siv hauv cov khoom nws tus kheej kuj tuaj yeem ua rau corrosion thiab oxidation ntawm cov khoom nws tus kheej.
