Kwiminyaka emibini edlulileyo, intsholongwane entsha ye-crown iyanda kwaye ubhubhane omtsha we-crown unzima kakhulu kwamanye amazwe. Thina bantu baqhelekileyo kufuneka sizikhusele ngokungqongqo, sinikele ingqalelo ekunxibeni iimaski (iimaski ezilahlwayo, iimaski zonyango ezilahlwayo okanyeIimaski ze-KN95, iimaski ze-N95) kwaye uqaphele umgama phakathi kwabantu, kwaye uzijolise kubo. Ukuze ufumane ulwazi lokuzikhusela, ungabhekisa kwiindlela ezilungileyo zaseTshayina zokuthintela ubhubhane. Ngale ndlela, impilo yethu, kuquka usapho lwakho, abahlobo, oogxa bethu, njl.njl., inokuhlala kude nentsholongwane kwaye yonwabele ubomi.
Ngoko ke, namhlanje, kunye noJin Haocheng, umenzi weilaphu elivuthuziweyo elinyibilikisiweyo (izinto zemaski), makhe sifunde ngendlela izinto ezisetyenziswa ngayoilaphu elivuthuziweyo elinyibilikisiweyokwiimaski.
Ilaphu eliqhushumbisiweyo lenziwe kakhulu nge-polypropylene, kwaye ububanzi befayibha bungafikelela kwi-1 ukuya kwi-5 microns. Kukho i-voids ezininzi, ulwakhiwo oluthambileyo, kunye nokukwazi okuhle ukulwa nemibimbi. Ezi fayibha zincinci kakhulu ezinesakhiwo se-capillary esahlukileyo zandisa inani kunye nommandla womphezulu weefayibha kwindawo nganye, ukuzeilaphu elivuthuziweyo elinyibilikisiweyoinokucoca kakuhle, ukukhusela, ukuthintela ubushushu kunye nokufunxa ioyile. . Ingasetyenziswa kwiindawo zomoya, izixhobo zokucoca ulwelo, izixhobo zokwahlukanisa, izixhobo zokufunxa, izixhobo zemaski, izixhobo zokuthintela ubushushu, izixhobo zokufunxa ioyile kunye namalaphu okusula.
Wonke umntu uyazi ukuba iimaski zonyango ziqulathe umaleko weilaphu elivuthuziweyo elinyibilikisiweyo, ngoko ke yintoni le nto isetyenziswayoimaski yezonyangoilaphu eliqhushumbisiweyo elenziwe ngalo?
Ilaphu eliqhushumbisiweyo elisetyenziswa kwimaski lenziwe ngezinto zepolypropylene, kwaye ilaphu eliqhushumbisiweyo elinyibilikisiweyo lenziwe ngezinto zepolypropylene ezibizwa ngokuba yi-high-melt fat fiber. Luhlobo lwelaphu le-electrostatic fiber elihle kakhulu, elinokusebenzisa umbane oqinileyo ukufunxa iintsholongwane, uthuli, amaconsi, esi sisizathu esibalulekileyo sokuba iimaski zikwazi ukucoca iintsholongwane. Iimaski zonyango zihlala zisebenzisa isakhiwo esineengqimba ezininzi, esibizwa ngokuba yisakhiwo seSMS: umaleko omnye we-spunbond (S) kumacala omabini. Kukho umaleko omnye okanye iingqimba ezininzi ze-meltblown (M) embindini. Eyona nto ilungileyo yomaleko we-meltblown yilaphu eliqhushumbisiweyo. Lililo elenziwe ngokucoca iintsholongwane kwiimaski, kwaye ilaphu eliphakathi le-M-meltblown non-woven. Enyanisweni, ezi ngqimba zintathu zonke zilaphu ezingalukwanga, kwaye izinto eziluhlaza zonke ziyipolypropylene, kodwa inkqubo yokuvelisa yahlukile. Phakathi kwazo, ububanzi befayibha yomaleko oqhoshumbisiweyo kumacala angaphakathi nangaphandle bubukhulu, malunga ne-20 microns; Ububanzi befayibha enyibilikisiweyo kumaleko ophakathi yi-2 microns kuphela, eyenziwe ngezinto ze-polypropylene ezibizwa ngokuba yi-high-melt fat fiber. Ibuthathaka kwaye ayinakuhlanjwa ngamanzi okanye itshizwe ngotywala. Nokuba imanzi kwaye yomile, iya konakalisa izicubu zefayibha kwaye ibangele iindawo ezivulekileyo. Ukuba iintsholongwane zingena kwiindawo ezivulekileyo, imaski ilahlekelwa ngamandla ayo okukhusela.
Ngenxa yemeko enzima yesifo esigqugqisayo, iimaski ziye zaba yinto ebalulekileyo kubomi bethu bokuhamba. Masiqonde ukuba kutheni iimaski zinokuthintela iintsholongwane? Okokuqala, umthamo we-coronavirus yi-80 ～120nm, kuba uhlala unamathele kulwelo lomzimba kwaye utshizwe. , Ngoko ke ngokubanzi mkhulu kune-0.1um (0.1 micron (um) = 100 nanometers (nm)). Ilaphu elinyibilikayo lisebenzisa i-polypropylene njengezinto eziphambili zokwenza imveliso, kwaye ububanzi befayibha bunokufikelela kwi-0.5-10um. Ukuba yintsholongwane enamathele kulwelo lomzimba, inokucoca.
Ngale ntshayelelo ingasentla, ngaba uyazi ngakumbi ngeemaski?
Ukuze ufumane ulwazi oluchanekileyo kunye nokubonisana malungaIlaphu elingalukwanga eliqhumayo nelinyibilikisiweyo, Imveliso Egqityiweyo Engalukwanga, Ilaphu elingelolukiweyo le-Spunlace, Ilaphu elingalukwanga lokucoca, I-Nonluken ebotshwe ngenaliti, wamkelekile ukuba uqhagamshelane neJin Haocheng Non-woven Fabric. Siza kwenza konke okusemandleni ethu ukukunceda.
