Paperboard Primary Air Lim nyob rau hauv Industrial Dust thiab Smoke Collection rau Cleanrooms
1. Txheej txheem cej luam ntawm Paperboard Primary Air Lim
Paperboard thawj cov ntxaij lim dej (tseem hu ua vaj huam sib luag lim los yog ua ntej-filters) feem ntau yog siv rau hauv cov khoom siv plua plav thiab cov pa luam yeeb, suav nrog cov chaw huv huv. Lawv lub luag haujlwm tseem ceeb yog khaws cov khoom loj (piv txwv li, plua plav, lint, paj ntoos) ua ntej huab cua mus txog siab dua -cov lim dej ua haujlwm zoo (piv txwv li, HEPA/ULPA), ncua lub neej ntawm cov lim dej hauv qab thiab txo cov nqi kho.
Cov yam ntxwv tseem ceeb:
Khoom siv: Ua los ntawm cov ntaub ntawv txheej los yog cov khoom siv hluav taws xob nrog cov corrugated los yog pleated tsim kom nce qhov chaw.
Kev ua tau zoo: Feem ntau ntsuasG3-G4 (EN779: 2012)los yogMERV 5–8 (ASHRAE 52.2), ntes 50-90% ntawm cov khoom loj dua lossis sib npaug li 5 μm.
Siab poob: Tsawg pib tsis kam (20-50 Pa), kom ntseeg tau tias siv zog tsawg.
Tus nqi -Cov: Tus nqi qis dua thiab cov qauv siv pov tseg ua rau lawv zoo tagnrho rau cov ntawv thov siab - ntim.
2. Daim ntawv thov hauv Cleanroom Dust and Smoke Collection
Hauv chav huv huv, thawj cov lim cua ua lub luag haujlwm tseem ceeb hauv:
Ua ntej-Kev lim rau HEPA/ULPA Systems:
Tshem tawm cov khoom ntxhib, tiv thaiv kev txhaws ntxov ntxov ntawm HEPA lim (uas yog kim los hloov).
Piv txwv li: Hauv chav tsev semiconductor cleanroom, G4 paperboard lim ntes 80% ntawm 10 μm hais ua ntej huab cua mus txog HEPA lim (H13 / H14).
Muaj pa taws thiab fume Control:
Siv nyob rau hauv vuam, laser txiav, los yog soldering fume extraction systems los ntxiab loj sparks thiab soot.
Piv txwv: G3 lim nyob rau hauv lub vuam fume extractor txo cov load ntawm downstream electrostatic precipitators.
Kev Tiv Thaiv HVAC:
Tiv thaiv plua plav buildup hauv ductwork thiab txias coils, txhim kho kev ua haujlwm zoo.
3. Qhov zoo ntawm Cleanroom Environments
| Qhov zoo | Kev piav qhia |
|---|---|
| Cov hmoov av siab -Tuav muaj peev xwm | Corrugated tsim tsub kom cov xov xwm saum npoo av, tso cai rau lub neej ntev kev pab cuam ua ntej hloov. |
| Kev kho qis | Cov lim dej pov tseg txo qis qis dua piv rau lwm txoj kev ntxuav tau. |
| Compatibility nrog Cleanroom Standards | Ua tau raws li ISO 14644-1 cov kev cai thaum siv nrog HEPA / ULPA lim. |
| Zog Efficiency | Tsis tshua muaj siab poob qis minimizes kiv cua siv zog. |
4. Kev txwv thiab kev txiav txim siab
Tsis yog rau Fine Particle Tshem Tawm:
Paperboard filters tsis tuaj yeem ntes cov sub-micron hais (piv txwv li,<1 μm), which require HEPA/ULPA filtration.
Humidity Sensitivity:
Paper media may degrade in high-humidity environments (relative humidity >80%).
Hluav taws kub muaj xwm txheej nyob rau hauv siab -Tswj daim ntawv thov:
Not suitable for temperatures >80℃tshwj tsis yog raug kho nrog nplaim taws- cov txheej txheem retardant.
5. Kev Xaiv Cov Cai rau Kev Siv Chav Dej
Kev ntsuas ntsuas:
Rau chav huv,G4 (MERV 8)raug pom zoo rau ua ntej- pom kom sib npaug ntawm tus nqi thiab kev ua haujlwm.
Hom Media:
Cov khoom siv hluav taws xob (xws li, polyester) yog nyiam tshaj daim ntawv hauv qhov chaw ntub lossis oily.
Kev tsim kho ncej:
Galvanized steel los yog noo noo-cov duab los qhia thav duab kom ruaj khov.
Airflow Resistance:
Xaiv cov ntxaij lim dej uas muaj tsawg dua lossis sib npaug li 50 Pa pib ua haujlwm kom tswj tau qhov system efficiency.
6. Case Study: Pharmaceutical Cleanroom
Scenario: Chav kawm 10,000 (ISO 7) chav huv yuav tsum tau ua ntej - pom rau HEPA- raws HVAC system.
Kev daws:
G4 paperboard limntsia saum toj kawg nkaus ntawm HEPA lim.
Kev tshwm sim: HEPA lim lifespan ncua ntawm 6 lub hlis mus rau 18 lub hlis, txo cov nqi hloov los ntawm 67%.
7. Cov lus qhia txog kev tu
Kev tshuaj xyuas tsis tu ncua: Hloov cov lim dej thaum lub siab poob siab tshaj 200 Pa lossis kev soj ntsuam pom pom pom tias muaj plua plav hnyav.
Teem caij hloov: Rau cov chav huv si tseem ceeb, hloov cov lim dej txhua 3-6 lub hlis tsis hais qhov poob siab.
Kev pov tseg kom raug: Siv cov ntxaij lim dej ua cov pov tseg uas muaj kev phom sij yog tias muaj cov kab mob lom (xws li cov hlau hnyav).
8. Lwm txoj rau Paperboard Lim
Washable Hlau Mesh Lim:
Tsim nyog rau daim ntawv thov rov siv tau tab sis tsis tshua muaj txiaj ntsig (G1-G2).
Synthetic Bag Lim:
Cov hmoov av siab dua (MERV 11–13) tab sis kim dua.
Tus kheej -Tshuaj lim:
Zoo tagnrho rau kev ua haujlwm tas mus li tab sis xav tau kev nqis peev tseem ceeb ua ntej.
9. Cov lus xaus
Paperboard thawj cua lim yog ib qhotseem ceeb thiab raug nqi - zootivthaiv nyob rau hauv cleanroom plua plav thiab pa luam yeeb systems. Los ntawm kev ntes cov khoom loj, lawv tiv thaiv cov ntxaij lim dej hauv qab HEPA / ULPA, txo cov nqi tu, thiab txhim kho tag nrho cov kev ntseeg tau. Txawm li cas los xij, lawv yuav tsum raug xaiv raws liefficiency, media hom, thiab ib puag ncig tej yam kev moblos xyuas kom meej qhov ua tau zoo hauv cov ntawv thov huv huv.
Rauhigh-humidity, oily, los yog high-kub ib puag ncig, hluavtaws lossis lwm hom lim yuav tsum raug txiav txim siab.
Koj puas xav kom tob tob rau hauv ib qho tshwj xeeb (piv txwv li, kev ntsuas kev ua haujlwm lim dej, tus nqi- kev tshuaj xyuas txiaj ntsig)?
