Muri iki gihe,idafite ubudodo bushongeshejweImyenda ikoreshwa cyane mu bijyanye n'ibikoresho byo kuyungurura. Kuva mu myaka ya 1970, hakozwe kandi hakoreshwa ikoranabuhanga ritandukanye ryo gushyushya hamwe n'ibikoresho byihariye byo kuyungurura hamwe n'amashanyarazi asanzwe binyuze mu kuvanga imigozi itandukanye. Umusaruro wihuse ni uburyo bwa elegitoroniki bugezweho. Kuri ubu, uburyo bwa elegitoroniki bukubiyemo cyane cyane kuzunguruka kwa elegitoroniki, gusharija korona, amashanyarazi asanzwe, polirisasiyo y'ubushyuhe, guturika kw'amashanyarazi make, indege y'amazi meza, nibindi. Bitewe n'imikorere itandukanye ya elegitoroniki y'ibikoresho, imiterere y'imibiri ya elegitoroniki nayo iratandukanye cyane, kandi hari itandukaniro mu kunoza imikorere yo kuyungurura no kugumana amashanyarazi.
Mu by’ukuri, ubushobozi bwo kuyungurura imyenda idafunze neza (meltblown nonwoven) buri munsi ya 70% gusa, kandi ntibihagije kwishingikiriza gusa ku ngaruka zo kuziba za mekanike zo guteranya imigozi myiza cyane hamwe n’imigozi mito, utuntu duto n’imyenge myinshi. Bitabaye ibyo, kongera ubunini bwa garama y’ibikoresho byongera cyane ubudahangarwa bwo kuyungurura. Kubwibyo, gushonga no gusukura ibikoresho by’iyungurura muri rusange byongera ingaruka zo gushyushya imyenda hakoreshejwe electrostatic electoral-electrode, kandi hakoreshejwe uburyo bwa electrostatic kugira ngo kunoze ubushobozi bwo gusukura, bushobora kugera kuri % kugeza kuri %. Ibyo ni ukuvuga kugira ngo huzuzwe ibipimo bya KN95 cyangwa hejuru yayo.
Ibikoresho bya electret air filter BIKORESHA polarity ya fibre ubwayo kugira ngo bikurure umukungugu w’amashanyarazi no gufata bagiteri na virusi. Umuvuduko w’amashanyarazi wa electret ya polypropylene fused jet fibre utandukanye n’uw’umukandara w’ibikoresho bisanzwe. Ntabwo ari siyansi gushushanya ibice by’impapuro kugira ngo hamenyekane niba spray ishongeshejwe irimo umuriro cyangwa niba mask ifite ubushobozi bwo kuyungurura hakoreshejwe amashanyarazi ashongeshejwe. Umuvuduko w’amashanyarazi ni umuriro w’igihe gito, ni uko umuriro w’ubuso uba uhujwe by’igihe gito. Umuvuduko w’amashanyarazi ni charge nziza na negative surface polarized charge, mu gihe charge ya electret fibre ari charge y’inyongera yongerwaho hakoreshejwe charge nyinshi z’amashanyarazi mu gihe cyo gutunganya electret. Izi charges zikwirakwizwa mu mwobo w’imbere wa fibre ishongeshejwe mu buryo bwa electret master nanoparticles. Ubudahangarwa bw’amazi bw’ibikoresho bya electret ishongeshejwe n’uruzitiro rwa fibre ishongeshejwe bituma izi charges zifungwa neza imbere. Iyo uduce duto gusa twinjiye imbere mu gice cy’icyuma gishongeshejwe, ingaruka za electrostatic n’imiterere ya fibre ishongeshejwe bitangira kugira uruhare.
Icyiswe amashanyarazi adahinduka ni uko ibikoresho bya polypropylene ishongeshejwe ubwabyo ari byo bikingira ubushyuhe, bikaba ari n'ubwoko bw'ibikoresho bya electpoles, bityo umuriro ntuzacika burundu, ngo ucike burundu. Umushahara w'amashanyarazi menshi usohoka ubitswe muri fibre igihe kirekire hamwe n'amashanyarazi ahagije. Byongeye kandi, ni ukubaho kw'imishahara myinshi, ntabwo ari ubwoko bw'imishahara iterwa no gushwanyagurika. Kubwibyo, kunyuzwa kwa macro ntibishobora kugaragaza neza imikorere ya mikorosikopi. Imiterere ya porosity nyinshi n'imiterere ya electret ifunguye ya fibres nziza cyane bikoreshwa mu gutanga imikorere myiza no kugabanya ubushobozi bwo kuyungurura. Mu buryo bukabije bwo gukora kwa bagiteri, umwenda wa electret ushongeshejwe utera imbaraga electrostatic field ikomeye na microelectronics urujya n'uruza rwa bagiteri, bigatuma poroteyine na aside nucleic mutation byangirika, bigasenya bagiteri zo mu buso, bikica bagiteri, birekura iyoni mbi za tourmaline ubwayo zahagaritse zimwe mu mikorere ya mikorobe za bagiteri, harimo n'uburyo bwo guhumeka, imikorere ya enzyme, kwimura imbaga kuva ku rukuta rw'uturemangingo, bityo bikabuza uturemangingo twa bagiteri kugira ingaruka za bagiteri.
