Menene hanyar tace HEPA?

1. Ƙa'idar mahimmanci: tsaka-tsakin Layer uku + motsi na Brownian

Tasirin Inertial

Manyan barbashi (> 1 µm) ba za su iya bin motsin iska ba saboda rashin aiki kuma kai tsaye sun buga ragar fiber kuma suna "manne".

Tsangwama

0.3-1 µm barbashi suna motsawa tare da streamline kuma an haɗa su idan suna kusa da fiber.

Yaduwa

Kwayoyin cuta da VOCs <0.1 µm suna tafiya ba bisa ka'ida ba saboda motsin Brownian kuma a ƙarshe fiber na kama su.

Electrostatic Jan hankali

Filayen haɗe-haɗe na zamani suna ɗaukar wutar lantarki na tsaye kuma suna iya ɗaukar ɓangarorin da aka caje, suna haɓaka aiki da wani 5-10%.

2. Matsayin inganci: H13 vs H14, kar kawai ku yi ihu "HEPA"

A cikin 2025, EU EN 1822-1: 2009 har yanzu zai kasance mafi yawan ma'aunin gwajin da aka ambata:

Daraja	0.3 µm Ingantacce	Misalai na Aikace-aikace
H13	99.95%	Mai tsabtace iska na gida, tace mota
H14	100.00%	Dakin tiyata na asibiti, dakin tsaftar semiconductor

3. Tsarin: Pleats + Partition = Maƙarƙashiyar Riƙe Ƙura

HEPAba "net" ba ne, amma haɗin fiber na gilashi ko PP tare da diamita na 0.5-2 µm, wanda ya cika ɗaruruwan lokuta kuma an raba shi da manne mai zafi mai zafi don samar da tsarin "gado mai zurfi" 3-5 cm lokacin farin ciki. Mafi yawan lallausan, mafi girman filin sararin sama da tsawon rayuwa, amma asarar matsa lamba kuma za ta karu. Samfuran ƙaƙƙarfan ƙaƙƙarfan ƙira za su ƙara matattarar MERV-8 don toshe manyan barbashi da farko kuma su ƙara zagayowar maye gurbin HEPA.

4. Maintenance: bambancin matsa lamba + sauyawa na yau da kullum

• Amfani da gida: Sauya kowane watanni 6-12, ko maye gurbin lokacin da bambancin matsa lamba shine>150 Pa.

• Masana'antu: Auna bambancin matsa lamba kowane wata, kuma maye gurbin shi idan ya kasance sau 2 na juriya na farko.

• Wankewa? ’Yan HEPA masu rufaffiyar PTFE ne kawai za a iya wanke su da sauƙi, kuma fiber ɗin gilashin zai lalace lokacin da ya haɗu da ruwa. Da fatan za a bi umarnin.

5. Shahararrun yanayin aikace-aikacen a 2025

• Gida mai wayo: Masu shara, kwandishan, da humidifiers duk an sanye su da H13 a matsayin ma'auni.

• Sabbin motocin makamashi: H14 cabin kwandishan tace kashi ya zama wurin siyar da samfura masu tsayi.

• Likita: Gidan PCR na wayar hannu yana amfani da U15 ULPA, tare da adadin riƙe ƙwayoyin cuta na 99.9995% ƙasa da 0.12 µm
