Izixhobo ze-Meltblown azikho esitokhweni kwihlabathi liphela kwaye zonke iifektri zigcwele, kodwa kukho into ephezulu yokucoca ethatha indawo yezixhobo ezinyibilikayo.Leyo yi-PTFE (polytetrafluoroethylene)!
Ukunxiba imaski yindlela ebalulekileyo nesebenzayo yokuhlukanisa intsholongwane kunye nokukhusela amaqela asengozini.Okwangoku, iimaski zinokusetyenziselwa ukwahlula iintsholongwane kunye namasuntswana e-PM2.5 ngeendlela ezimbini:
(1) I-electrostatic adsorption, eyindlela esebenzayo yokwahlula, isebenzisa amandla e-electrostatic phakathi kwemicu ephakathi kwe-mask ukubhengeza iibhaktheriya kunye namasuntswana amancinci ukufikelela ukuzimela kunye nokukhusela;
(2) Ukwahlula ngokwasemzimbeni kuyindlela yokwahlula yodwa, esebenzisa i-pore encinci ye-mask ngokwayo ukuvimba ukuhlasela kweebhaktheriya kunye neentsholongwane.Indlela yokwahlula ngokwasemzimbeni ikakhulu isebenzisa ifuthe lomxhuzulane, isiphumo sokucalula, isiphumo sokusasazwa, kunye nesiphumo se-inertia yebhaktiriya kunye namasuntswana amahle.
Iimfuno zoyilo lweemaski zoqhaqho lwezonyango ngokubanzi zinokuvala amasuntswana e-aerosol ebhaktheriya amakhulu kune-3 microns ububanzi, kodwa ngenxa yobubanzi bepore yomgangatho ongundoqo wemaski, ukwahlula ngokwasemzimbeni kwamasuntswana amancinci ebhaktheriya kunye neentsholongwane akunakufezekiswa ngokugqibeleleyo.Iimaski ezinjalo zisebenzisa ikakhulu iindlela ze-electrostatic adsorption.Nangona kunjalo, njengoko ixesha lokunxiba lisanda (njengeyure enye ukuya kwezi-2), imaski iba manzi ngenxa yemisebenzi yabantu efana nokuphefumla umntu osinxibileyo, kwaye amandla ayo okuthengisa nge-electrostatic ayancipha, kwaye umphumo wokuzihlukanisa uya uba mandundu ngokuthe ngcembe.Ke ngoko, iimaski eziqhelekileyo zoqhaqho lwezonyango azikwazi ukufikelela ukwahlula kunye nokukhusela ixesha elide.
Ukwanda kwemfuno yeemaski kwihlabathi jikelele ibe ngumxholo wehlabathi jikelele.Amalaphu anyibilikisiweyo abizwa ngokuba yimaski "intliziyo" ekuqaleni aqale ngaphantsi kwe-3,000 yeedola ngetoni, kwaye ngoku ixabiso linyuke ngaphezulu kwe-40,000 yeedola!
Kulo mongo, ukutshintshwa kwamalaphu e-mask meltblown kuye kwaba ngumxholo oshushu kumaxesha amva nje!Izixhobo ze-Meltblown azikho esitokhweni kwihlabathi liphela kwaye zonke iifektri zigcwele, kodwa kukho into ephezulu yokucoca ethatha indawo yezixhobo ezinyibilikayo.Leyo yi-PTFE (polytetrafluoroethylene)!
Yintoni efanelwe ingqwalasela ephezulu kukuba iimaski ze-PTFE ze-nano eziveliswe nge-PTFE (i-polytetrafluoroethylene) njengeyona nto iphambili ekrwada ibe yindlela entsha yokuphuhliswa kweemaski kwixesha elizayo!
Iimaski zeNano ziye zaba sisigqubuthelo sokhuselo sezonyango ngenxa yokusebenza kwayo kakuhle kokucoca.Ngokufana neemaski eziqhelekileyo zonyango, iimaski ze-nano antibacterial zikwaquka umaleko wangaphandle, umaleko ophakathi, umaleko wangaphakathi, i-ear hook, ikliphu yempumlo kunye namanye amalungu.Iimaski ze-Nano zikhethekileyo kuba uluhlu oluphakathi lwenziwe nge-nano-membrane kunye nobukhulu obuncinci be-pore (100-200 nanometers), eyenziwa ngokubanzi nge-PTFE.IIfilimu ye-PTFEiveliswe ngendlela yokwelula engafaniyo okanye ye-biaxial ine-spider web-like microporous structure kumphezulu, kwaye ine-dimensional-dimensional structure enotshintsho oluntsonkothileyo olufana noqhagamshelo lwenethiwekhi, ukusetwa komngxuma, kunye nokugoba kwetshaneli, ngoko ke ineeMpawu ezibalaseleyo zokuhluza umphezulu.
Iimaski zeNano ezenziwe ngezinto ze-PTFE zineempawu zokuphumelela okuphezulu komqobo, ukunxiba ixesha elide, ukukhanya kunye nokuphefumla, kwaye yindlela entsha yophuhliso lweemaski kwixesha elizayo.Nangona kunjalo, okwangoku, iimaski ezinjalo ze-PTFE zibiza kakhulu kwaye azikwazi ukuthatha indawo ngokupheleleyo iimaski zemveli.
