0.1mm lim

Nyob rau xyoo 1980s, lub lim dej nrog kev ua haujlwm siab dua li "kev ua haujlwm siab". Tom qab ntawd, cov lus piav qhia thiab kev sim cov txheej txheem ntawm HEPA lim tau hloov kho, thiab cov lus tshiab tau hloov "0.1mm lim".

Lub npe tseem ceeb rau US tsoom fwv tus qauv rau chav huv, FED-STD-209. Lub Koom Haum Thoob Ntiaj Teb rau Standardization tau qiv tus lej 209 thaum nws tsim Pawg Pabcuam Kev Ua Haujlwm Huv Huv (ISO/TC209).

484mm

Classic loj ntawm domestic baffle lim. Saib "HEPA Lim Dimensions".

863 qhov kev pab cuam

Thaum Lub Peb Hlis 3, 1986, plaub tus kws tshawb fawb tau sau tsab ntawv mus rau CPC Central Committee, thov kom taug qab lub ntiaj teb qib siab thiab tsim cov thev naus laus zis tshiab. Ib nrab xyoo tom qab ntawd, lub xeev tau tshaj tawm Daim Ntawv Qhia Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Txhim Kho Tshiab, lossis "863 Program" luv luv.

Lim manufacturers feem ntau hais txog 863 thiab tau ua tiav muag lawv cov khoom rau txhua qhov chaw ntawm 863 qhov kev pab cuam. 863 tau ua raws li "Project 973".

project 908

Lub yim hli ntuj 1990, lub xeev tau pom zoo ib tug loj-scale integrated circuit project. Ob peb xyoos tom qab, lwm qhov haujlwm loj ua hauv Shanghai tau dhau los ua 909.

99.97%

Kev lig kev cai, lub cim HEPA lim efficiency Performance index.

Cov lim dej HEPA ntxov tshaj plaws hauv Tebchaws Meskas muaj qhov ua tau zoo ntawm 99.97 feem pua ​​​​rau 0.3mm hais, uas yog siab me ntsis rau lub sijhawm. Tam sim no, tus naj npawb sensational efficiency yog 99.999999%.

Laminar flow hood

Local high efficiency filtration system nrog nws tus kheej kiv cua. Nws tau siv los xa mus rau lub kaw lus nrog lub kiv cua lossis ib qho array ntawm cov ntxaij lim dej. Tam sim no nws kuj tseem tuaj yeem xa mus rau FFU.

Kev Ua Phem Pib. Pib tiv thaiv

Qhov tsis kam ntawm cov lim tshiab hauv kev siv tiag tiag lossis hauv kev sim ntsuas, lossis qhov tsis kam ntawm cov lim tshiab hauv qab ntsuas huab cua.

Rated Airflow. Rated airflow

Nominal cua ntim tau thov los ntawm cov chaw tsim khoom.

Cov lim dej yog "qhov ncauj qhov ntswg," thiab ua pa yog nyob ntawm tus neeg siv. Tsis tas yuav tsum tau them nyiaj ntau dhau rau qhov "rated" kom muaj nuj nqis los ntawm tus neeg muag khoom, muaj ntau ntau ntses.

Particle Diameter, Particle Loj. Particle diam, particle loj

A: Txoj kab uas hla ntawm plua plav, lo lus nug yooj yim dhau. Ib zaug ntxiv, lub cheeb ntawm ib daim ntawm dandruff yog dab tsi, lub blob ntawm E. coli, ib txoj hlua ntawm ib nrab-hlawv coke hais?

Lub ntiaj teb kev tshawb fawb sib cav txog lub ntsiab lus ntawm qhov loj me, thiab qee zaum cov kws tshawb fawb tau koom nrog. Cov lag luam hauv zej zog yog qhov zoo ntawm kev sib koom tes thiab txhais tau tias: Txoj kab uas hla ntawm ib qho chaw uas tsim cov lus teb, los ntawm cov khoom siv particle-sizing, uas sib npaug rau teb ua los ntawm particle raug ntsuas.

Thaum lub laser particle txee yog siv los ntsuas tej yam ntawm cov plua plav, lub txee muab lub cheeb ntawm ib tug particle sib npaug rau lub teeb pom kev zoo ntawm ib tug qauv Latex sphere (sphere nrog ib tug tshwj xeeb kho qhov muag cov cuab yeej thiab ib tug heev cov duab) siv nyob rau hauv lub calibration. ntsuas.

HEPA lim. Hepa lim

Ib txwm hais: Rau 0.3mm particle filtration efficiency ≥99.97% lim.

Cov lus hais hauv tsev: nrog kev ntsuas hluav taws xob sodium, efficiency ≥99.97% lim.

Lub teb chaws tus qauv yuav tsum tau hloov kho: Lim nrog efficiency ≥99.9%, kuaj los ntawm sodium nplaim taws txoj kev.

Nuclear Grade Filter Nuclear qib lim

Kev lag luam nuclear ua haujlwm hauv nws lub voj voog, nrog nws tus kheej cov qauv zoo thiab cov kev cai xeem. Txhua hom huab cua lim siv nyob rau hauv kev lag luam nuclear yog sib sau ua ke hu ua "nuclear grade filters".

Inhalable Particulate Matter, IP. Inhalable particle teeb meem, IP

Cov khoom me me uas tuaj yeem nkag mus rau hauv tib neeg txoj kev ua pa qis. Cov ntaub ntawv inhalable particulate yog tag nrho qhov hnyav ntawm cov khoom me me nrog qhov me me ntawm 10mm lossis tsawg dua rau ib lub cubic meter ntawm huab cua. Saib "Particulate Matter".

photocatalyst

Ntawd yog, photocatalysis. "Catalysis" txhais tau tias "catalyst" hauv Nyij Pooj, thiab nws kuj tau hu ua "catalyst" hauv qee phau ntawv Suav ntev dhau los.

Thaum raug ultraviolet lub teeb, tej yam volatile organic tebchaw (VOCs) hloov mus rau hauv cov pa roj carbon dioxide molecules thiab dej molecules thaum lawv los rau hauv kev sib cuag nrog ultra-fine titanium dioxide hmoov (nano-titanium). Titanium dioxide ua raws li ib tug catalyst ntawm no.

Cov tub ntxhais kawm ntawv theem nrab nkag siab "catalysis", tab sis cov xibfwb tsis paub "catalyst", yog li cov lag luam siv cov chij ntawm "photocatalyst". Ob xyoos tom qab nws tau nrov, "photocatalyst" tau los ua "nanotechnology" vim nws cov nanometrics.

Lim Efficiency

Qhov piv ntawm cov hmoov av ntes los ntawm lub lim rau cov hmoov av nkag mus rau hauv lub lim. Saib cov kev ua tau zoo thiab kev sim rau cov ntsiab lus ntxiv.

Vim tias txoj kev sim, ntsuas lub xeev, cov qauv plua plav siv hauv qhov kev sim thiab cov txheej txheem kev kho ntawm cov ntaub ntawv xeem muaj ntau yam, qhov tseem ceeb ntawm kev pom kev ua haujlwm ntawm tus nqi kuj txawv.

Feem ntau, txoj kev xeem yuav tsum tau qhia rau ntawm qhov Performance index.

Tus naj npawb ntawm Cua Hloov

Qhov piv ntawm huab cua muab rau chav ntim hauv ib teev.

Kev tu Kom huv

Qhov kev txwv ntawm cov khoom me me tshaj qhov loj me ntawm ib chav tsev nyob hauv chav huv lossis qhov chaw huv. Saib Tshooj 6.1 "Cleanliness Classification".

Tuam Tshoj Contaminant Control Society. Tuam Tshoj Contaminant Control Society

Tuam Tshoj Clean Society tau tsim nyob rau hauv 1982, vim hais tias qhov loj ntawm lub zej zog tsis loj, raws li txoj cai, txuas nrog Suav Society of Electronics, yog ib tug "secondary society", lub npe tag nrho ntawm "Suav Society of Electronics huv si technology. ceg". Rau tib lub laj thawj, Tuam Tshoj Aerosol Society yog lub koom haum thib ob txuas nrog Suav Granular Society.

lim

Cua lim rau tsheb, sab hauv combustion engine, compressed cua thiab lwm yam lag luam. Feem ntau cylindrical, siv tshwj xeeb ntoo pulp fiber lossis tshuaj fiber ntau lim ntawv. Lus Askiv kuj yog Filter. Cov neeg nyob hauv cov kev lag luam no nyiam hu lawv "filters" vim tias lawv koom nrog ntau qhov chaw tsim khoom thiab kev siv.

Dust Capacity plua plav-tuav muaj peev xwm

Qhov hnyav ntawm lub lim kom tuav cov plua plav cuav uas tau teev tseg thaum qhov kev txiav txim siab tau teev tseg lossis pom zoo nrog cov txheej txheem kev xeem, siv cov qauv siv cov plua plav, saib "Phaub muaj peev xwm".

Cov neeg sab saum toj hauv kev lag luam lim txhais peb cov lus "plua plav muaj peev xwm" rau "kev muaj kuab paug".

Lub neej expectancy. Lub neej expectancy

Lub sij hawm thaum lub lim tsis kam mus txog qhov kawg qhov kev tawm tsam, los yog lub sij hawm thaum tus neeg siv xav tias cov lim yuav tsum tau muab pov tseg.

Yog tias koj xav ua tus neeg muag khoom lim lossis tus kws tsim tshuab cua txias, lub neej expectancy yog ib lo lus nug nug.

Tus nqi nkag nkag

Transmittance = 1 -- pom efficiency

Lub transmittance kuj hu ua "tus nqi nkag".

Subhigh efficiency lim

Cov khoom siv tshwj xeeb hauv tsev, sodium nplaim hluav taws xob txoj kev ua haujlwm ≥95% lim.

Cov khoom txawv teb chaws uas zoo sib xws (H10) feem ntau yog siv rau prefiltration ntawm high efficiency lim.

Thaum kawg Resistance kawg kuj

Txhawm rau txiav txim siab qhov ntsuas qhov ntsuas qhov ua haujlwm tsis zoo, saib "filter resistance".

Raws li qhov kev pom zoo ntawm tus neeg siv thiab tus neeg sim, qhov ntsuas qhov ntsuas tsis zoo los txiav txim siab cov plua plav tiam ntawm cov lim. Saib "dust peev".

Hluav taws xob

Cov khoom siv dielectric muaj peev xwm khaws cia ntev ntawm qhov chaw thiab cov nqi dipole.

"Standing" yog ntev ntev, "ncej" hais txog polarity lossis nqi, uas yog, cov khoom siv hluav taws xob zoo li qub rau lub sijhawm ntev. Hauv kev lag luam pom, electret hais txog cov tshuaj fiber ntau lim cov khoom siv nrog cov hluav taws xob zoo li qub, xws li PP cov khoom siv rau cov cua lim, PTFE lim ntawv rau kev ua haujlwm siab lim.
