Okwamanje,okungalukiwe okuncibilikisiweIzindwangu zisetshenziswa kabanzi emkhakheni wezinto zokuhlunga. Kusukela ngawo-1970, kuye kwathuthukiswa futhi kwasetshenziswa ubuchwepheshe obuhlukahlukene bokushaja kanye nezihlungi ezihlukile ezinama-electrostatic charges ngokuxuba imicu ehlukene. Umphumela osheshayo inqubo yamanje ye-electrostatic electret. Njengamanje, izindlela ze-electret zifaka phakathi ukuphotha kwe-electrostatic, ukushaja kwe-corona, ugesi wokungqubuzana, ukuhlukaniswa kokushisa, ukubhomba kwe-electron beam yamandla aphansi, i-pure water jet, njll. Ngenxa yezinqubo ezahlukene ze-electrostatic electret zezinto, izakhiwo zemizimba ye-electret ezakhiwe nazo zihlukile kakhulu, futhi kukhona umehluko ekuthuthukisweni kokusebenza kokuhlunga kanye nokuphikelela kwe-electrostatic.
Eqinisweni, ukusebenza kokuhlunga kwezindwangu ezingezona ezelukiwe ezincibilikisiwe kungaphansi kuka-70% kuphela, futhi akwanele ukuthembela kuphela kumphumela wokuvimba ngomshini wokuhlanganiswa kwezintambo ezi-three-dimensional ezinezintambo ezincane, izikhala ezincane kanye ne-porosity ephezulu. Ngaphandle kwalokho, ukukhulisa nje ubukhulu besisindo segremu yezinto kuzokwandisa kakhulu ukumelana kokuhlunga. Ngakho-ke, izinto zokuhlunga ezincibilikisiwe nezifafazwayo ngokuvamile zengeza umphumela wokushaja we-electrostatic endwangu yokuncibilikisa nokufafaza ngenqubo ye-electrostatic electoral-electrode, futhi zisebenzisa indlela ye-electrostatic ukuthuthukisa ukusebenza kahle kokuhlunga, okungafinyelela ku-% kuya ku-%. Lokho kungukuhlangabezana nezinga le-KN95 noma ngaphezulu.
Izinto zokuhlunga umoya ze-Electret ZISEBENZISA i-polarity yefayibha ngokwayo ukumunca uthuli oluyi-electrostatic futhi zibambe amabhaktheriya namagciwane. Ishaja kagesi ye-electret ye-polypropylene fused jet fiber ihlukile kweyebhande lokushayisana lezinto ezivamile. Akuyona isayensi ukudweba izingcezu zephepha ukuze kunqunywe ukuthi i-spray encibilikisiwe ishaja noma ukuthi imaski inokusebenza kokuhlunga ngokusebenzisa ugesi wokushayisana. I-Friction electrification iyishaja yesikhashana, uma ishaja engaphezulu iqoqwe okwesikhashana. Ishaja yokushayisana iyishaja ehlanganisiwe esezingeni eliphezulu nelibi, kuyilapho ishaja yefayibha ye-electret iyishaja yangaphakathi eyengeziwe engezwe ngokusebenzisa ishaja ephezulu ye-voltage ngesikhathi senqubo ye-electret. Lawa mashaja ahlakazeka ngaphakathi kwe-porous yefayibha encibilikisiwe ye-ultrafine ngesimo se-electret master nanoparticles. Ukumelana kwamanzi kwezinto ze-jet encibilikisiwe kanye nesithiyo sefayibha ye-ultrafine kwenza la mashaja avalelwe ngokuqinile ngaphakathi. Lapho izinhlayiya ezincane kuphela zingena ngaphakathi kwengqimba ye-jet encibilikisiwe, umphumela we-electrostatic kanye nesakhiwo sefayibha ye-ultrafine kuqala ukudlala indima.
Lokhu okubizwa ngokuthi ugesi oqinile kungenxa yokuthi izinto ezincibilikisiwe ze-polypropylene ngokwazo ziyavikela, futhi ziwuhlobo lwezinto ze-electpoles, ngakho-ke ishaja ngeke isuswe ngokungahleliwe, ihlakazeke ngokungahleliwe. Ishaja yokukhipha i-voltage ephezulu eyengeziwe igcinwa ku-fiber isikhathi eside ngeshaja kagesi eyanele. Ngaphezu kwalokho, ukuba khona ndawonye kwamacala amaningi, hhayi uhlobo lweshaja oludalwa ukungqubuzana. Ngakho-ke, i-macro adsorption ayikwazi ukukhombisa ngqo ukusebenza kweshaja encane. Izakhiwo ze-porosity ephezulu kanye ne-electrostatic evulekile ye-electrostatic electret yezintambo ze-ultrafine zisetshenziselwa ukuhlinzeka ngokusebenza kahle okuphezulu kanye nekhwalithi yokuhlunga ephansi yokumelana. Endleleni yokusebenza kwe-antibacterial kakhulu, indwangu encibilikisiwe ivuselela insimu enamandla ye-electrostatic kanye nokugeleza kwe-microelectronics kwamagciwane, yenze umonakalo wayo we-protein kanye ne-nucleic acid mutation, ibhubhise amagciwane esakhiwo sobuso, ibulale amagciwane, ikhulule ama-ion amabi i-tourmaline ngokwayo ivimbe amanye amagciwane izinqubo ze-metabolic microbial, kufaka phakathi uhlelo lokuphefumula, umsebenzi we-enzyme, ukudluliselwa kwesisindo kusuka odongeni lweseli, ngaleyo ndlela ivimbele amangqamuzana amagciwane abe nomphumela wokulwa namagciwane.
Singabantuumenzi wendwangu engalukiwe encibilikisiwe, wamukelekile ukusibonisana ~
