1. Cov Cuab Yeej Siv Hluav Taws Xob
- Smelting txheej txheem: Thaum lub sij hawm smelting txheej txheem ntawm txhuas alloys, roj combustion nyob rau hauv lub cub tawg ua combustion pa gases xws li carbon dioxide, carbon monoxide, nitrogen oxides, thiab sulfur dioxide. Ib txhij, qee qhov impurities thiab additives nyob rau hauv aluminium alloy muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm qhov kub thiab txias, tsim cov plua plav-laden pa gases thiab volatile organic compounds (VOCs).
- Tuag Casting Txheej Txheem: Thaum lub tshuab tuag casting ua haujlwm, qhov siab - qhib thiab kaw ntawm pwm, txau thiab txias ntawm cov hlau molten, thiab lwm yam, ua kom muaj cov plua plav ntau ntau - cov pa tawm pa thiab cov pa kub. Tsis tas li ntawd, cov pwm tso tawm cov neeg ua haujlwm thiab cov roj lubricating siv hauv cov txheej txheem tuag casting kuj volatilize ntawm qhov kub thiab txias, tsim cov pa roj carbon monoxide.
- Tshaj tawm- txheej txheem txheej txheem: Deburring, sandblasting, polishing, thiab lwm yam kev tshaj tawm- cov kauj ruam ua tiav ua kom muaj cov pa roj ntau ntau. Nyob rau tib lub sijhawm, qee qhov txheej txheem kho saum npoo (xws li anodizing) yuav siv cov tshuaj reagents, tsim cov kua qaub lossis alkaline tso pa tawm.
2. Cov yam ntxwv ntawm Cov Hluav Taws Xob Hluav Taws Xob
- Complex Composition: Cov pa pa muaj ntau yam kuab paug, nrog rau cov pa roj inorganic los ntawm combustion, hlau plua plav, VOCs, thiab acidic los yog alkaline gases. Cov txheej txheem tsim khoom sib txawv thiab cov khoom siv raw ua rau muaj kev hloov pauv hauv qhov muaj pes tsawg leeg ntawm cov pa pa.
- Kub Kub: Cov pa hluav taws xob tsim tawm thaum lub sij hawm smelting thiab tuag- cov txheej txheem casting muaj qhov kub thiab txias, feem ntau nyob ib ncig ntawm 100-300 degree, xav tau kev kho cua txias ua ntej kev kho cov pa roj tom qab.
- Cov ntsiab lus siab plua plav: Cov plua plav tso pa tawm thaum lub sij hawm xa tawm - cov txheej txheem kho muaj cov hmoov av uas muaj qhov loj me me, xws li micrometers mus rau millimeters, thiab nyob rau ntawm qhov siab, ua rau nyuaj rau kev kho cov pa roj.
- Cov ntxhiab tsw ntxhiab: Qee cov pa roj carbon monoxide thiab cov pa roj acidic muaj cov ntxhiab tsw ntxhiab, xws li cov ntxhiab tsw uas tsim los ntawm volatilization ntawm cov neeg ua hauj lwm tso tawm thiab cov ntxhiab tsw ntxhiab ntawm cov kua qaub tso pa tawm, uas tuaj yeem cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv.
