Feem ntau ntawm cov khoom paug hauv kev kuaj kev laus muaj xws li ambient air particulate matter, biological and chemical contaminants qhia los ntawm cov neeg khiav dej num, residues hauv cov khoom siv, thiab dej los yog gaseous media siv thaum lub sij hawm xeem. Cov kab mob no tuaj yeem cuam tshuam nrog cov txheej txheem kev laus ntawm cov khoom, ua rau kev txiav txim siab ntawm kev ua tau zoo lossis cov txiaj ntsig kev xeem tsis raug.
1. Ambient Air Contaminants: Qhov Tseem Ceeb Ntawm Kev Tawm Tsam Sab Nraud
Yog tias chav kuaj tsis raug kaw kom zoo lossis lub tshuab cua tsis tau lim, cov kab mob sab nraud tuaj yeem nkag tau yooj yim.
Particulate Matter (PM2.5 / PM10): Plua plav, paj ntoos, thiab hmoov av muaj peev xwm ua raws li tus qauv saum npoo, cuam tshuam rau qhov sib xws ntawm lub teeb raug thiab tshav kub.
Gaseous Pollutants:
Ozone (O₃): Muaj zog oxidizing tus neeg sawv cev, accelerates roj hmab tawg.
Nitrogen Oxides (NOx): Koom nrog cov tshuaj tiv thaiv photochemical, txhawb cov khoom degradation.
Sulfur Dioxide (SO₂): Ua ke nrog cov dej noo los tsim cov kua qaub, corroding hlau thiab coatings.
Microorganisms: Pwm spores proliferate nyob rau hauv siab kub thiab av noo, ua rau pwm loj hlob ntawm cov ntaub ntawv organic.
Kev Tiv Thaiv thiab Tswj Cov Lus Pom Zoo: Muab cov cua nkag nrog HEPA siab - lim dej + cov pa roj carbon adsorption txheej, thiab hloov cov lim dej tsis tu ncua.
3. Cov pa phem qhia los ntawm cov neeg ua haujlwm: Tib neeg yam tsis tuaj yeem tsis quav ntsej. Cov neeg ua haujlwm nkag mus thiab tawm hauv thaj chaw yog qhov txuas tseem ceeb hauv kev sib kis ntawm cov pa phem.
Cov tawv nqaij flakes, cov plaub hau, thiab cov kua qaub ncaug: Nqa cov kab mob uas tuaj yeem ua rau muaj qhov kub thiab txias.
Tes roj thiab hws: Muaj cov ntsev thiab cov organic acids, uas tuaj yeem ua rau muaj kev xeb hauv zos lossis kev hloov pauv ntawm cov khoom siv kho qhov muag thaum sib cuag nrog cov qauv.
Cov hmoov seem ntawm cov hnab looj tes: Cov hnab looj tes latex tso tawm talc, ua paug rau qhov chaw rhiab heev.
Kev tiv thaiv thiab tswj cov lus pom zoo: Hnav hmoov- hnab looj tes dawb thiab lub qhov ncauj qhov ntswg, siv cov tweezers tsis muaj menyuam, thiab txo qhov zaus ntawm kev qhib qhov rooj.
4. Ntsuam xyuas cov kab mob nruab nrab: Kev tswj dej thiab roj zoo. Cov xov xwm tsis huv uas siv rau kev txau, humidification, lossis tswj huab cua yuav ncaj qha qhia cov kab mob.
Deionized dej tsis ua raws li cov qauv: Cov ions seem (xws li Cl⁻, Ca²⁺) ua rau electrochemical corrosion lossis scale tsim.
Compressed cua uas muaj roj thiab dej: Unfiltered compressed cua nqa roj pos huab thiab condensate, paug tus qauv.
Inert gas impurities: Nitrogen lossis argon roj sib xyaw nrog oxygen lossis noo noo cuam tshuam qhov tseeb ntawm kev kuaj tshuaj antioxidant.
Kev tiv thaiv thiab kev tswj xyuas cov lus pom zoo: Siv siab - dej purity deionized (resistivity Ntau dua lossis sib npaug ntawm 18.2 MΩ·cm), thiab teeb tsa cov roj- dej cais thiab tshuab ziab khaub ncaws.
5. Qauv tus kheej - tso tawm: Internal contamination qhov chaw. Qee cov ntaub ntawv tso tawm cov khoom me me hauv qab cua sov lossis lub teeb raug, ua rau tus kheej - paug.
Plasticizer tsiv teb tsaws: Cov ntaub ntawv xws li PVC tso phthalates, cuam tshuam rau cov qauv uas nyob ib sab.
Antioxidant volatilization: Antioxidants precipitate ntawm qhov kub thiab txias, tsim cov roj zaj duab xis rau saum npoo.
Polymer degradation khoom: VOCs xws li formaldehyde thiab benzene tebchaw sib sau ua ke hauv qhov chaw kaw.
Kev tiv thaiv thiab tswj cov lus pom zoo: Txhim kho cov qauv kev ywj pheej nrog qhov sib txawv txaus; nce qhov cua zaus kom tshem tawm cov volatiles.
Cov ntsiab lus: Cov pa phem nthuav dav tag nrho cov saw hlau los ntawm "ib puag ncig- neeg ua haujlwm- khoom siv- xov xwm- qauv." Tsim kom muaj kev kaw- lub voj voog kev tswj hwm los ntawm kev ntxuav ua ntej thiab kev tiv thaiv txheej txheem kom xaus- ntawm - kev saib xyuas yeeb nkab yog qhov tseem ceeb lav rau kev ua kom muaj tseeb thiab kev ntseeg siab ntawm cov ntaub ntawv kev laus sai.
