Menene hanyar matattarar HEPA?

1. Babban ƙa'ida: katsewar layuka uku + motsi na Brownian

Tasirin Inertial

Manyan ƙwayoyin cuta (>1 µm) ba za su iya bin iskar da ke shiga ba saboda rashin ƙarfin iska kuma su buga ragar zare kai tsaye kuma su "manne".

katsewa

Ƙwayoyin 0.3-1 µm suna motsawa tare da layin da aka haɗa kuma ana haɗa su idan suna kusa da zare.

Yaɗuwa

Kwayoyin cuta da VOCs <0.1 µm suna yawo ba bisa ka'ida ba saboda motsin Brownian kuma daga ƙarshe zare ya kama su.

Jan Hankalin Electrostatic

Zaruruwan haɗakar zamani suna ɗauke da wutar lantarki mai tsauri kuma suna iya sha ƙwayoyin da aka caji, suna ƙara inganci da wani kashi 5-10%.

2. Matsayin inganci: H13 da H14, kada ku yi ihu kawai "HEPA"

A shekarar 2025, EU EN 1822-1:2009 zai kasance ma'aunin gwaji da aka fi ambata:

Matsayi	Inganci 0.3 µm	Misalan Aikace-aikace
H13	99.95%	Mai tsarkake iska na gida, matatar mota
H14	100.00%	Dakin tiyata na asibiti, ɗakin tsafta na semiconductor

3. Tsarin: Pleats + Partition = Matsakaicin Ƙarfin Riƙe Kura

HEPAba "net" ba ne, amma haɗin zare na gilashi ko PP mai diamita na 0.5-2 µm, wanda aka yi masa liƙa sau ɗaruruwa kuma aka raba shi da manne mai zafi don samar da tsarin "gado mai zurfi" mai kauri cm 3-5. Yawan liƙa, girman yankin saman kuma tsawon rai, amma asarar matsi kuma zai ƙaru. Samfuran masu inganci za su ƙara matattarar MERV-8 don toshe manyan ƙwayoyin cuta da farko kuma su tsawaita zagayowar maye gurbin HEPA.

4. Kulawa: ma'aunin matsin lamba daban-daban + maye gurbin yau da kullun

• Amfani a gida: A maye gurbin duk bayan watanni 6-12, ko a maye gurbin idan bambancin matsin lamba ya wuce 150 Pa.

• Masana'antu: Auna bambancin matsin lamba a kowane wata, sannan a maye gurbinsa idan ya ninka juriyar farko sau biyu fiye da na farko.

• Ana iya wankewa? Za a iya wanke HEPA kaɗan masu rufi da PTFE kaɗan, kuma za a lalata zaren gilashin idan ya taɓa ruwa. Da fatan za a bi umarnin.

5. Shahararrun yanayin aikace-aikace a cikin 2025

• Gida mai wayo: Ana sanya wa masu gogewa, na'urorin sanyaya daki, da na'urorin humidifiers duk a cikin H13 a matsayin misali.

• Sabbin motocin makamashi: Matatar tace iska ta H14 ta zama wurin sayarwa ga manyan samfura.

• Likitanci: Ɗakin PCR na wayar hannu yana amfani da U15 ULPA, tare da ƙimar riƙe ƙwayoyin cuta na 99.9995% ƙasa da 0.12 µm
