Iyo Yakajairwa Material uye Giredhi Chikamu cheHEPA Sefa Net

Izvo zvakajairika zvinhu zveHEPA sefa

Ndezvipi zvinhu zvakajairika zveHEPA sefa?Kune akawanda marudzi ezvigadzirwa zvinogadzira HEPA, inogona kupatsanurwa kuita PP (polypropylene) sefa bepa, PET sefa bepa, PP uye PET composite sefa bepa uye girazi fiber sefa bepa.PP (polypropylene) ipepa, saka kazhinji haigone kugezwa.

Chimwe chikamu cheHEPA sefakushandisa PET kana PTFE zvinhu, iyo ndiyo mavambo ezvinyorwa zvakawanda paInternet kugeza HEPA filter, asi pano kukuyeuchidza kuti kushanda kwePET kwakaderera zvikuru.PP (polypropylene) sefa bepa;Iyo itsva sefa zvinhu zvakagadzirwa nepolypropylene nenzira yakakosha inopisa yekunyungudika.Chigadzirwa chacho chine acid uye alkali resistance, corrosion resistance, high melting point, stable performance, isingaravike, yunifomu kugovera, nekudzikisira kushoma, kushanda kwepamusoro, simba rakawanda zvichingodaro.

PET sefa bepa: Yakagadzirwa nepolyester resin uye zvimwe zvinhu zvine kuomarara kwakanyanya, kuomarara kwakanaka, kushorwa kwecorrosion, kupisa kwekushisa kwakanyanya uye kuita kwakagadzikana.Inowanzo shandiswa mukutsvaira, vacuum cleaner nemimwe midziyo yemumba ine yakaderera yekusefa zvinodiwa kana michina mikuru yekuchenesa.

Composite sefa bepa (PP nePET): inoumbwa sefa bepa, yakangoti chidimbu chePP melt-spray, uyezve chidimbu chePET melt-spray, kuitira kuti abatanidze zvakanakira PP nePET: nyore kuumba, kusefa. kururama kunogona kusvika;Zvese kuoma uye yakakwirira chaiyo kusefa mhedzisiro inogona kuwanikwa.

Girazi fiber sefa bepa: Girazi faibha sefa bepa, yakakwira goridhe yemukati sefa bepa, yakashandiswa muindasitiri yenyukireya.

Kusarudzika kwakajairwa kwemazinga eHEPA

Masefa emhepoakakamurwa kuita G1-G4, F5-F9, H10-H14 uye U15-U17 maererano neEuropean giredhi.H giredhi inowanikwa mune zvinonatsa mweya.Iyi tsanangudzo ndeyekunyanya kushanda zvakanaka kana sub-high kunyatsoshanda sefa net.TheH13 sefa bepa rinogona kuzadzisa kushanda kwese kwe99.95%.Kunyatsoshanda kweHEPA sefa bepa negiredhi H14 kunogona kusvika 99.995%.

Ehe, muyero yeEuropean, iyo yakakwira yekucheneswa giredhi yeHEPA sefa iU giredhi, pakati payo kucheneswa kwese kweU17 giredhi HEPA sefa inogona kutosvika 99.99999%.Nekudaro, nekuti mutengo wekugadzira weU-giredhi HEPA sefa wakakwira, uye zvinodiwa nharaunda yekugadzira zvakaomarara.Saka hapana zvakawanda zvinogona kushandiswa pamusika.
