Ngoku,ilaphu elingalukwanga eliqhushumbisiweyozisetyenziswa kakhulu kwicandelo lezinto zokucoca. Ukusukela ngeminyaka yoo-1970, kuye kwaphuhliswa kwaye kwasetyenziswa iindlela ezahlukeneyo zokutshaja kunye nezihluzo ezizodwa ezinee-electrostatic charges ngokuxuba iifayibha ezahlukeneyo. Isiphumo esikhawulezileyo yindlela yangoku ye-electrostatic electret. Iindlela eziphambili ze-electret okwangoku ziquka ukujikeleza kwe-electrostatic, ukutshaja kwe-corona, umbane we-friction, i-thermal polarization kunye ne-low energy electron beam bombardment. Ngenxa yeendlela ezahlukeneyo ze-electrostatic electret (iinkqubo) zezinto, iimpawu zemizimba ye-electret ezenziweyo nazo zahlukile kakhulu.
Enyanisweni, ukusebenza kokuhluza kwe-meltblown nonwoven kungaphantsi kwe-70% kuphela, kwaye akwanelanga ukuxhomekeka kuphela kwisiphumo sokuvimba koomatshini sokuhlanganiswa kwe-three-dimensional fibers ye-ultrafine ene-fibres ecolekileyo, i-voids encinci kunye ne-porosity ephezulu. Ngaphandle koko, ukwandisa nje ubukhulu begram yezinto kuya kwandisa kakhulu ukumelana nokuhluza. Ke ngoko, izixhobo zokuhluza i-melting spray ngokubanzi zongeza i-electrostatic charge effect kwilaphu lokuhluza i-melting ngenkqubo yokukhetha i-electrostatic. Ukusebenza kokuhluza kunokufikelela kwi-99.9% ukuya kwi-99.99% ngokusebenzisa indlela ye-electrostatic.KN95 standard.
Izinto zokucoca umoya ze-Electret ZISEBENZISA i-polarity yefayibha ngokwayo ukufunxa uthuli lwe-electrostatic nokubamba iintsholongwane. Iipropathi ze-electrostatic eziphezulu kunye ne-electrostatic evulekileyo yeefayibha ze-ultrafine zisetyenziselwa ukubonelela ngokusebenza okuphezulu kunye nomgangatho wokucoca ophantsi wokuxhathisa. Kwindlela yokusebenza kakhulu ye-antibacterial, ilaphu le-electret elinyibilikisiweyo livuselela intsimi enamandla ye-electrostatic kunye nokuhamba kwe-microelectronics yeebhaktheriya, lenze umonakalo kwi-protein kunye ne-nucleic acid mutation, litshabalalise iibhaktheriya zesakhiwo somphezulu, libulale iibhaktheriya, likhuphe ii-ions ezingezizo i-tourmaline ngokwayo ivale ezinye iinkqubo ze-metabolic zebhaktheriya, kubandakanya inkqubo yokuphefumla, umsebenzi we-enzyme, ukudluliselwa kobuninzi ukusuka eludongeni lweseli, ngaloo ndlela kuthintele iiseli zebhaktheriya ukuba zibe nefuthe le-antibacterial.
Izinto zokucoca i-melting-jet electret zibamba amasuntswana ikakhulu ngesenzo esiphindwe kabini sesithintelo soomatshini kunye nokutsalwa kwe-electrostatic. Ukumelana noomatshini kunxulumene ngokusondeleyo nolwakhiwo kunye neempawu zezinto: xa ilaphu lokutshiza elinyibilikisiweyo litshajwa yi-corona nge-voltage yamakhulu aliqela ukuya kwiikhilovolts ezininzi, iifayibha ziyasasazeka kwinethiwekhi yemingxunya ngenxa yokugxothwa kwe-electrostatic, kwaye ubungakanani phakathi kweefayibha bukhulu kakhulu kunobungakanani bothuli, ngaloo ndlela kwakheka isakhiwo esivulekileyo. Xa uthuli ludlula kwizinto zokucoca i-jet ezinyibilikisiweyo, isiphumo se-electrostatic asinakutsala kuphela amasuntswana othuli atshajiweyo ngokufanelekileyo, kodwa sikwabamba amasuntswana angathathi hlangothi ngesiphumo sokungenisa i-electrostatic. Okukhona amandla aphezulu e-electrostatic ezinto, kokukhona uxinano lwetshaja lwezinto luphezulu, itshaja ephezulu, kokukhona itshaja ephezulu, kokukhona isiphumo se-electrostatic siqina. Ukukhutshwa kwe-Corona kunokuphucula kakhulu ukusebenza kokucoca kwelaphu lokutshiza le-polypropylene. Ukongezwa kwamasuntswana e-tourmaline kunokuphucula ngokufanelekileyo ukusebenza kwe-electret, kwandise ukusebenza kokucoca, kwandise ukumelana kokucoca, kwandise uxinano lwetshaja yomphezulu wefayibha, kwaye kwandise amandla okugcina i-fiber net. Isiphumo esibanzi singcono xa i-6% ye-tourmaline electret kongezwa. Izinto ze-electret ezininzi endaweni yoko ziya kwandisa ukunganyamezeli kwentshukumo yomthwali.
Ngasentla malunga noku: yintoni ukungeniswa kwelaphu elingalukwanga le-melt spray, ndinethemba lokuba siza kukunceda; SiyilaI-BEF99 inyibilika,ukucoca i-meltblown,Ilaphu elingelolukiweyo elinyibilikisiweyo lemaski yobusoWamkelekile ukubonisana ~
