Parizvino,isina kurukwa yakanyungudukaMachira anoshandiswa zvakanyanya mumunda wezvinhu zvekusefa. Kubva kuma1970, matekinoroji akasiyana-siyana ekuchaja uye mafirita akasiyana ane machaji emagetsi nekusanganisa mafiber akasiyana akagadzirwa uye akashandiswa. Mhedzisiro yacho pakarepo ndiyo nzira yemagetsi emagetsi iripo. Parizvino, nzira dzemagetsi dzinosanganisira kutenderera kwemagetsi, kuchaja kwekorona, friction electrification, thermal polarization, low-energy electron beam bombardment, pure water jet, nezvimwewo. Nekuda kwemaitiro akasiyana emagetsi emagetsi emagetsi, hunhu hwemiviri yemagetsi inoumbwa hwakasiyanawo, uye kune misiyano mukuvandudzwa kwekushanda kwekusefa uye kuramba kwemagetsi.
Kutaura zvazviri, mashandiro ekusefa kwemachira asina kucheneswa emeltblown ari pasi pe70% chete, uye hazvina kukwana kungovimba chete nemhedzisiro yekuvharira kwemechanical yekubatanidzwa kwetatu-dimensional fibers nefibers dzakapfava, ma voids madiki uye porosity yakakwira. Zvikasadaro, kungowedzera ukobvu hwemagiramu echinhu kunowedzera zvakanyanya kuramba kwekusefa. Naizvozvo, kunyungudutsa nekupfapfaidza zvinhu zvefirita zvinowanzowedzera electrostatic charge effect ku melting and spraying jira kuburikidza ne electrostatic electoral-electrode process, uye shandisa nzira ye electrostatic kuvandudza mashandiro ekusefa, ayo anogona kusvika % kusvika %.Ndiko kuti isangane neKN95 standard kana pamusoro.
Zvinhu zveElectret air filter zvinoshandisa polarity yefiber pachayo kunyudza guruva nekubata mabhakitiriya nemavhairasi. Chaja yemagetsi ye electret ye polypropylene fused jet fiber yakasiyana neyebhandi rekukweshana rezvinhu zvakajairwa. Hazvisi zvesainzi kudhirowa zvidimbu zvepepa kuti utonge kana spray yakanyungudutswa yachajwa kana kuti mask ine mashandiro ekusefa kuburikidza nemagetsi ekukweshana. Kukweshana kwemagetsi ichaja yenguva pfupi, kana chaja yepamusoro yaunganidzwa kwenguva pfupi. Chaja yekukweshana ichaja yakanaka neisina kunaka pamusoro, nepo chaja ye electret fiber ichaja yemukati yakawedzerwa nekushandisa chaja yepamusoro panguva ye electret. Machaja aya anopararira mukati me porous ye fiber yakanyungudutswa muchimiro che electret master nanoparticles. Kudzivirira mvura kwejet yakanyungudutswa uye chipingamupinyi che ultrafine fiber zvinoita kuti machaja aya avharwe zvakasimba mukati. Kana zvidimbu zvidiki chete zvikapinda mukati me jet layer yakanyungudutswa, electrostatic effect uye chimiro che ultrafine fiber zvinotanga kutamba basa.
Iyo inonzi magetsi asingachinjiki imhaka yekuti polypropylene yakanyungudutswa jet zvinhu pachayo zvinodzivirira, zvakare rudzi rwezvinhu zve electpoles, saka chaji haizombodzivisiki zvisina tsarukano, kunyangarika zvisina tsarukano. Chaji yepamusoro inobuda mu fiber kwenguva yakareba ine chaji yemagetsi yakakwana. Uyezve, ihwo hukama hwemachaji akawanda, kwete rudzi rwechaji inogadzirwa nekukweshana. Naizvozvo, macro adsorption haigone kuratidza zvakananga mashandiro echaji microscopic. Hunhu hwepamusoro hwe porosity uye hwakavhurika electrostatic electret hwemafiber e ultrafine hunoshandiswa kupa kushanda kwepamusoro uye hunhu hwakaderera hwekupfapfaidza. Munzira yakanyanya yekurwisa mabhakitiriya, jira re electret rakanyungudutswa rinosimudzira simba re electrostatic field uye microelectronics kufamba kwemabhakitiriya, kuita kukuvara kweprotein ne nucleic acid mutation, kuparadza mabhakitiriya epamusoro pechimiro, kuuraya mabhakitiriya, kuburitsa ma negative ions tourmaline pachayo yakavhara mamwe mabhakitiriya maitiro e metabolic microbial, kusanganisira respiratory system, basa re enzyme, kutamiswa kwehuwandu kubva pamadziro esero, nokudaro zvichidzivirira masero ebhakitiriya ane antibacterial effect.
Isu tirimugadziri wemachira asina kurukwa akanyungudutswa, tinokugamuchirai kuti mutibvunze ~
