Amacandelo aphambili kwisicoci soMoya se-HEPA

I-HEPA (iNdlela yokuSebenza ngokuPhezuluIsihluzi soMoya).IUnited States yaseka iqela elikhethekileyo lophuhliso ngowe-1942 yaza yavelisa imathiriyeli exutyiweyo yefibre yomthi, asbestos, kunye nomqhaphu.Ukusebenza kwayo kokucoca kufikelele kwi-99.96%, eyona ndlela i-embryonic ye-HEPA yangoku.Emva koko, iphepha lokucoca i-glass fiber hybrid laphuhliswa kwaye lasetyenziswa kwitekhnoloji yeathom.Kwagqitywa ekugqibeleni ukuba izinto eziphathekayo zinomsebenzi wokuloba ongaphezulu kwe-99.97% ye-0.3μm yamasuntswana, kwaye yabizwa ngokuba yi-HEPA filter.Ngelo xesha, izinto zokucoca zenziwe nge-cellulose, kodwa izinto eziphathekayo zineengxaki zokunganyangeki komlilo kunye ne-hygroscopicity.Ebudeni bexesha, iasbestos nayo yayisetyenziswa njengesixhobo sokucoca, kodwa yayiza kuvelisa izinto ze-carcinogenic, ngoko ke izinto zokucoca zesihluzo esisebenza ngokuphezulu sisekwe ikakhulu kwifiber yeglasi ngoku.

I-ULPA (Isihluzo soMoya sokuNgena okuPhantsi kweUltra).Ngophuhliso lweesekethe ezidityanisiweyo ze-ultra-scale, abantu baye baphuhlisa i-ultra-high-effective filter ye-0.1μm yamasuntswana (umthombo wothuli useyi-DOP), kunye nokusebenza kwayo kokucoca kufikelele ngaphezu kwe-99.99995%.Yayibizwa ngokuba sisihluzo se-ULPA.Xa kuthelekiswa ne-HEPA, i-ULPA inesakhiwo esihlangeneyo kunye nokusebenza kakuhle kokucoca.I-ULPA isetyenziswa ikakhulu kushishino lombane okwangoku, kwaye akukho zingxelo zezicelo kwiamacandelo amayeza kunye nezonyango.
