Ifihla ingaphakathi le-indwangu encibilikisiweIzinto zokuhlunga zenziwe nge-polypropylene superfine fibre kanye nokusatshalaliswa okungahleliwe, ukubukeka, ubucwebe be-fiber yezinto ezibushelelezi, ezithambile nezimhlophe obungu-0.5 kuya ku-1.0 mu m, ukusatshalaliswa okungahleliwe kwe-fiber ukunikeza amathuba amaningi okubopha ukushisa phakathi kwe-fiber ngaleyo ndlela kwenze izinto zokuhlunga igesi ezincibilikisiwe zibe nendawo enkulu ethile, ukugoba okuphezulu (75%) noma ngaphezulu. Ngokusebenza kahle kokuhlunga kwe-stationer ye-voltage ephezulu, umkhiqizo unezici zokumelana okuphansi, ukusebenza kahle okuphezulu kanye nomthamo wothuli oluphezulu.
Ingaphakathi lemaski
Indwangu engalukiwe encibilikisiwe njengohlobo olusha lwezinto zokuhlunga ezisebenza kahle kakhulu yimaski "yenhliziyo", uma iqhathaniswa nezinto zokuhlunga zendabuko, ukuhlunga umoya kanye nokusebenza kahle kokuhlanza kube ngcono izikhathi eziyikhulu, manje isilungele kakhulu izinto zokuvikela impilo yezinto eziphilayo (ikhabhoni esebenzayo nezinto ezifanayo zingasetshenziswa amakhemikhali okuvikela, ngokumelene namagciwane namagciwane ngaphandle komsebenzi wokuhlanza ukuhlunga). Ukuzalwa kwayo kungazelelwe ngobusuku obubodwa umsebenzi wezokwelapha USEBENZISA imaski ye-gauze yeminyaka eyikhulu isuswe ngokuphelele. Ukuvikelwa kwezokwelapha ngokuvamile kuhlukaniswe ngamazinga amathathu ngokuya ngezinga lezidingo zokuvikela. "Amamaski okuhlinzwa" aluhlaza okwesibhakabhaka esiwagqoka kakhulu angasetshenziswa ekuvikeleni okuyinhloko, ikakhulukazi ekudlulisweni okuyingozi kwamaconsi aqukethe izifo empilweni yansuku zonke nasekukhiqizweni. Isinyathelo esiyinhloko sokuthuthukisa ikhono lokuvikela ukwengeza ungqimba lokuhlunga olwenziwe ngendwangu engalukiwe encibilikisiwe phakathi kwemaski.
Ingqimba yokuvikela ephakathi kwemaski (ingqimba ka-M emfushane) yindwangu engalukiwe e-polypropylene encibilikisiwe, kanti izinhlangothi zangaphambili nangemuva zemaski ziyizingqimba ezisontekile (ingqimba ka-S emfushane). Kuye ngezinga lokuvikelwa elidingekayo, kungafakwa izendlalelo eyodwa kuya kweziningi kungqimba ka-M. Uma kuyimaski yokuvikela yezinga 1, sebenzisa ungqimba ka-M. Kumshini wokuphefumula wezinga 3 njenge-N95, ungqimba ka-M lungadinga izendlalelo ezintathu zendwangu engalukiwe encibilikisiwe noma ngaphezulu. Vele, uma izendlalelo eziningi zengqimba ka-M, kulapho ukungena komoya okubi kakhulu kwemaski, imikhiqizo ethile izohluka.
Uma sidabula imaski, sizobona izingqimba ezintathu ezingenhla, okungukuthi ungqimba oluyi-hygroscopic, ungqimba lwesihlungi esiyinhloko, kanye nongqimba lwesivimbeli samanzi.
Indwangu yokufutha encibilikayo, etholakala phakathi kwesendlalelo sesihlungi semaski, ingahlunga amabhaktheriya, ivimbele ukusabalala kwamagciwane. Indwangu yokufutha encibilikayo, indwangu yokufutha encibilikayo ikakhulukazi ibe yi-polypropylene njengezinto eziyinhloko zokusetshenziswa, ububanzi befayibha bungafinyelela ku-1 ~ 5 micron. Lezi zindwangu ezi-ultrafine ezinesakhiwo esiyingqayizivele se-capillarity zandisa inani nendawo yobuso bezintambo endaweni ngayinye, ukuze indwangu yokufutha ibe nezakhiwo ezinhle zokuhlunga, ukuvikela, ukuvikela kanye nokumunca uwoyela. Ingasetshenziswa emoyeni, ezintweni zokuhlunga uketshezi, ezintweni zokuhlukanisa, ezintweni zokumunca, ezintweni zemaski, ezintweni zokuvikela ukushisa, ezintweni ezimunca uwoyela kanye nendwangu yokusula kanye neminye imikhakha.
Ukuvalelwa kanye nokumuncwa
Indwangu ecibilikisiwe iwuhlobo lwe-polypropylene ene-index ephezulu yokuncibilika, eyenziwe ngemicu eminingi ecibilikisiwe ebekwe ngendlela engahleliwe. Ububanzi bemicu busukela kuma-micron angu-0.5 kuya kwangu-10, kanti ububanzi bemicu bungaba yingxenye eyodwa kwezingamashumi amathathu zezinwele.
Njengoba kungabonakala esithombeni, kusenezikhala eziningi kumaski ngaphansi kwe-electron microscope. Ngakho singalivimba kanjani leli gciwane?
Amamaskivikela amagciwane ngokwenza izinto ezimbili: ukubamba kanye nokubamba
Ukuvalelwa:
Izinto zokuhlunga zithembele ezinqubweni zendwangu noma ezingalukiwe ukuze kufezwe ubuningi bezintambo esikhaleni futhi kwakhiwe inethiwekhi ethile yama-pores, ngaleyo ndlela kwakha umphumela "wokuvimba" emoyeni ogelezayo. Izinhlayiya ezinkulu emoyeni "zibanjwa" ngokushayisana nezintambo noma ngokuvimba kwe-fiber mesh ohlangothini lwezinto zokuhlunga. Ezinhlayiyeni ezingezona eziphilayo emoyeni (njengothuli, i-PM2.5, njll.), ukusebenza kahle kokuhlanza kwamaski kuncike kakhulu ekhonweni elilodwa lokuvimba izinto zokuhlunga.
Ukumuncwa:
Kumaski okuvikela ezinto eziphilayo, ngenxa yobukhulu obuncane kakhulu bezinto ezibangela izifo ezifana namagciwane, kunzima ukuhlanza iningi lezinto eziyingozi ngokuvimba izikhala ze-mask fiber. Ngakho-ke, ukumuncwa kwe-electrostatic sekuyisici esibalulekile somsebenzi wokuvikela imaski. Imicu yemvelo yendabuko ibuthakathaka kakhulu ekukhiqizeni nasekuthwaleni ugesi omile, ngakho-ke amamaski e-gauze anomphumela omncane wokumuncwa. Futhi i-non-polar polymer melt jet fiber iyinto enhle kakhulu yokukhiqiza nokugcina i-electrostatic (leli phuzu, ungaqhathanisa umuzwa wokugqoka izingubo zikakotini ezihlanzekile nezingubo ze-chemical fiber), okwenza kube "ngokwemvelo" okune-adsorption enhle kakhulu. Abacwaningi benze umsebenzi omningi wokuthi bangakhiqiza futhi balondoloze kanjani ukusebenza kahle kwe-electrostatic kwezinto zokuhlunga. Ekukhiqizweni kwemaski, kusetshenziswa izindlela zemishini noma ze-elekthronikhi ukuze kucebiswe ishaja ye-electrostatic ibe yizinto ezincibilikisiwe zokufafaza.
Ngenxa yekhono eliyingqayizivele lokumuncwa kwe-electrostatic, ubuchwepheshe bokuncibilikisa i-melting spray bungakhiqiza imicu yamakhemikhali enobubanzi obuncane kakhulu kunobomicu bemvelo, okubuye kube nomthelela ekudalweni kokumuncwa kwamakhemikhali. Indwangu engalukiwe encibilikisiwe nge-polypropylene ngokungangabazeki iyisinqumo sokuqala sezinto zokuvikela imaski yezokwelapha.
