Meltblown zvinhu zvapera pasirese uye mafekitori ese akazara, asi kune yakakwirira-yekupedzisira sefa zvinhu inotsiva meltblown zvinhu.Ndiyo PTFE (polytetrafluoroethylene)!
Kupfeka mask inzira yakakosha uye inoshanda yekuparadzanisa hutachiona uye kudzivirira mapoka anotambura.Parizvino, masks anogona kushandiswa kupatsanura mabhakitiriya uye PM2.5 zvimedu nenzira mbiri:
(1) Electrostatic adsorption, inova nzira inoshanda yekuzviparadzanisa nevamwe, inoshandisa simba remagetsi riri pakati pemafiber ari pakati pemasiki kushambadza mabhakitiriya uye twudiki twudiki kuti uwane kuzviparadzanisa nekudzivirira;
(2) Kuzviparadzanisa nevamwe inzira yekuzviparadzanisa nevamwe, iyo inoshandisa diki pore chimiro chemasikisi pachayo kudzivirira kupinda kwebhakitiriya nemavhairasi.Nzira yekuzviparadzanisa nevamwe inonyanya kushandisa simba rinokwevera zvinhu pasi, mhedzisiro, mhedzisiro yekupararira, uye inertia mhedzisiro yebhakitiriya uye zvimedu zvakanaka.
Izvo zvinodikanwa zvekugadzira zvemasikirwo ekuvhiya akajairwa anogona kuvharira mabhakitiriya aerosol zvimedu zvakakura kupfuura 3 microns padhayamita, asi nekuda kweiyo hombe pore dhayamita yepakati layer yemask, kuparadzaniswa kwemuviri kwezvimedu zvidiki zvebhakitiriya uye mavhairasi hazvigone kuwanikwa zvakakwana.Masiki akadaro anonyanya kushandisa electrostatic adsorption Nzira.Nekudaro, sezvo nguva yekupfeka ichiwedzera (senge 1 kusvika maawa maviri), mask inonyorova nekuda kwezviitiko zvevanhu sekufema kweanoipfeka, uye kugona kwayo kwe electrostatic adsorption kunodzikira, uye mhedzisiro yekuzviparadzanisa zvishoma nezvishoma inowedzera.Naizvozvo, akajairwa masiki ekuvhiya ekurapa haakwanise kuwana kwenguva yakareba inobudirira yekuzviparadzanisa nevamwe uye kudzivirira.
Kuwedzera kwekudiwa kwepasi rose kwemask kwave musoro wepasi rose.Machira akanyunguduka anozivikanwa se "moyo" masiki akatanga kutanga ari pasi pemadhora zviuru zvitatu patani, uye ikozvino mutengo wakakwira kupfuura madhora makumi mana!
Muchirevo chechinyorwa chino, kutsiva kwemachira akanyungudika machira zvakare yave nyaya inopisa munguva pfupi yapfuura!Meltblown zvinhu zvapera pasirese uye mafekitori ese akazara, asi kune yakakwirira-yekupedzisira sefa zvinhu inotsiva meltblown zvinhu.Ndiyo PTFE (polytetrafluoroethylene)!
Chinofanirwa kutariswa zvakanyanya ndechekuti PTFE nano masiki anogadzirwa nePTFE (polytetrafluoroethylene) seyo huru mbishi yakave nzira nyowani yekuvandudzwa kwemasiki mune ramangwana!
Nano masks ave chifukidzo chekudzivirira chekurapa chinoshanda nekuda kwekuita kwayo kwakanyanya kusefa.Zvakafanana nemasiki ekurapa akajairwa, nano antibacterial masks zvakare ine yekunze layer, yepakati layer, yemukati layer, nzeve hoko, mhino clip uye zvimwe zvikamu.Nano masks akakosha pakuti iyo yepakati layer inogadzirwa nano-membrane ine diki pore saizi (100-200 nanometers), iyo inowanzo gadzirwa nePTFE.ThePTFE firimuinogadzirwa neunidirectional kana biaxial kutambanudza nzira ine dandemutande-senge microporous chimiro pamusoro, uye ine mativi matatu-dimensional chimiro chine shanduko dzakaomarara senge network yekubatanidza, kugadzika kwegomba, uye kubhenda kwechanera, saka ine yakanakisa kusefa kwepamusoro Zvimiro.
Nano masks akagadzirwa kubva kuPTFE zvinhu ane hunhu hwepamusoro chipingamupinyi kunyatsoshanda, hurefu hwakapfeka hupenyu, huremu uye hunofema, uye itsika nyowani yekuvandudza masks mune ramangwana.Nekudaro, parizvino, masks ePTFE akadaro anodhura uye haakwanise kutsiva zvachose masiki echinyakare.
