Parizvino,jira risina kurukwa rakanyungudutswa rakaputikaZvinoshandiswa zvakanyanya mukugadzira zvinhu zvekusefa. Kubva kuma1970, matekinoroji akasiyana-siyana ekuchaja uye mafirita akasiyana ane ma electrostatic charges nekusanganisa mafiber akasiyana akagadzirwa uye akashandiswa. Mhedzisiro yacho pakarepo ndiyo nzira ye electrostatic electret iripo. Nzira huru dze electret parizvino dzinosanganisira electrostatic spinning, corona charging, friction electrification, thermal polarization uye low energy electron beam bombardment. Nekuda kwenzira dzakasiyana dze electrostatic electret (maitiro) ezvinhu, hunhu hwe electret bodies dzakaumbwa hwakasiyanawo.
Kutaura zvazviri, mashandiro ekusefa emeltblown nonwoven ari pasi pe70% chete, uye hazvina kukwana kungovimba chete nemhedzisiro yekuvharira kwemechanical yekuunganidza kwethree-dimensional fibers ye ultrafine fibers ine fine fibers, small voids uye high porosity. Zvikasadaro, kungowedzera ukobvu hwemagiramu echinhu kunowedzera zvakanyanya resistance yekusefa. Naizvozvo, melting spray filter materials inowanzo wedzera electrostatic charge effect ku melting spray cloth kuburikidza ne electrostatic electing process. Kushanda kwekusefa kunogona kusvika 99.9% kusvika 99.99% nekushandisa electrostatic method.KN95 standard.
Zvinhu zveElectret air filter zvinoshandisa polarity yefiber pachayo kunyudza guruva nekubata mabhakitiriya nemavhairasi. Mapurosity akakwira uye hunhu hwakavhurika hwe electret ye ultrafine fibers zvinoshandiswa kupa kushanda kwepamusoro uye kunaka kwekusefa kusingadzivisike. Munzira yakanyanya yekurwisa mabhakitiriya, jira re electret rakanyungudika rinosimudzira simba re electrostatic field uye microelectronics flow yebhakitiriya, rinoita kuti protein ne nucleic acid mutation zvikanganise, rinoparadza mabhakitiriya epamusoro pechimiro, richiuraya mabhakitiriya, richiburitsa ma negative ions. tourmaline pachayo inovhara mamwe mabhakitiriya. metabolic process, kusanganisira respiratory system, basa re enzyme, kutamiswa kwehuwandu kubva pamadziro esero, nokudaro zvichidzivirira masero emabhakitiriya ane antibacterial effect.
Zvinhu zvinonyungudutsa - jet electret filter zvinobata zvidimbu zvakanyanya kuburikidza nekuita kaviri kwechinhu chinodzivisa uye electrostatic adsorption. Kuramba kwemuchina kwakabatana zvakanyanya nechimiro uye hunhu hwezvinhu: kana jira rekupfapfaidza rakanyungudutswa richichajwa ne corona ne voltage yemazana akati wandei kusvika kumakilovolts akati wandei, shinda dzinopararira mu network yemakomba nekuda kwekudzoserwa kwemagetsi, uye saizi iri pakati peshinda yakakura kupfuura saizi yeguruva, nokudaro zvichigadzira chimiro chakavhurika. Guruva parinopfuura nepakati pechinhu chinonyungudutswa chejet filter, electrostatic effect haingogone kukwezva zvidimbu zveguruva zvakachajwa zvinobudirira, asiwo kubata zvidimbu zvisina kusimba zvakasanganiswa ne electrostatic induction effect. Kana simba remagetsi rechinhu chacho rakakwira, huwandu hwechaji hwechinhu hwakwira, point charge yakawanda, electrostatic effect yakasimba. Kubuda kweCorona kunogona kuvandudza zvakanyanya mashandiro ekupfapfaidza kwepolypropylene melting - jira rekupfapfaidza. Kuwedzera zvidimbu zvetourmaline kunogona kuvandudza mashandiro e electret zvinobudirira, kuwedzera mashandiro ekupfapfaidza, kuderedza kuramba kwekupfapfaidza, kuwedzera huwandu hwekushaja hwepamusoro hwefiber, uye kuwedzera kugona kwekuchengetedza fiber. Mhedzisiro yakazara iri nani kana 6% tourmaline electret inowedzerwa. Zvinhu zvemagetsi zvakawandisa zvinozowedzera kusashanda zvakanaka kwemuchina wekutakura zvinhu.
