Indwangu encibilikisiwe ekwimaski yenziwe ngani? JINHAOCHENG

Eminyakeni emibili edlule, igciwane elisha lomqhele liyabhebhetheka futhi ubhubhane olusha lomqhele lubi kakhulu kwamanye amazwe. Thina bantu abavamile sidinga ukuzivikela ngokuqinile, sinake ukugqoka imaski (imaski elahlwayo, imaski yezokwelapha elahlwayo nomaAmamaski e-KN95, imaski ye-N95) futhi unake ukuqhelelana kwabantu, futhi uziqondise bona. Ukuze uthole ulwazi lokuvikela, ungabheka izindlela ezinhle kakhulu zaseShayina zokuvimbela ubhubhane. Ngale ndlela, impilo yethu, okuhlanganisa umndeni wakho, abangani, ozakwethu, njll., ingahlala kude negciwane futhi ijabulele impilo.

Ngakho-ke, namuhla, kanye noJin Haocheng, umenzi weindwangu epheshuliwe encibilikisayo (impahla yemaski), ake sifunde ngendlela izinto zeindwangu epheshuliwe encibilikisayokumaski kwenziwa.
　
Indwangu eqhunyisiwe encibilikisiwe yenziwe kakhulu nge-polypropylene, futhi ububanzi befayibha bungafinyelela kuma-micron angu-1 kuya kwangu-5. Kunezikhala eziningi, isakhiwo esithambile, kanye nekhono elihle lokulwa nemibimbi. Lezi zindwangu ezincane kakhulu ezinesakhiwo esiyingqayizivele se-capillary zandisa inani nendawo yobuso befayibha endaweni ngayinye, ukuzeindwangu epheshuliwe encibilikisayoinokuhlunga okuhle, ukuvikela, ukuvikela ukushisa kanye nokumunca uwoyela. . Ingasetshenziswa emikhakheni yomoya, izinto zokuhlunga uketshezi, izinto zokuhlukanisa, izinto zomunca, izinto zemaski, izinto zokuvikela ukushisa, izinto zomunca uwoyela kanye nezindwangu zokusula.

Wonke umuntu uyazi ukuthi imaski yezokwelapha iqukethe ungqimba lwe-indwangu epheshuliwe encibilikisayo, ngakho-ke yini into esetshenziswayoimaski yezokwelaphaindwangu ecibilikisiwe eyenziwe ngayo?

Indwangu epheshulwe nge-melt esetshenziswa kumaski yenziwe ngezinto ze-polypropylene, kanti indwangu epheshulwe nge-melt nayo yenziwe ngezinto ze-polypropylene ezibizwa ngokuthi i-high-melt fat fiber. Luhlobo lwendwangu ye-electrostatic fiber ecolekile kakhulu, engasebenzisa ugesi oqinile ngempumelelo ukumunca amagciwane, uthuli, ama-Droplets, lokhu futhi kuyisizathu esibalulekile sokuthi kungani amaski ekwazi ukuhlunga amagciwane. Amaski ezokwelapha ngokuvamile asebenzisa isakhiwo esinezingqimba eziningi, esibizwa ngokuthi isakhiwo se-SMS: ungqimba olulodwa lwe-spunbond (S) kuzo zombili izinhlangothi. Kukhona ungqimba olulodwa noma izingqimba eziningi ze-meltblown (M) phakathi. Izinto ezinhle kakhulu zengqimba ye-meltblown yindwangu ye-meltblown. Yinto eyinhloko yokuhlunga amagciwane amaski, kanye nendwangu ephakathi ye-M-meltblown non-woven. Eqinisweni, lezi zingqimba ezintathu zonke ziyizindwangu ezingezona ezilukiwe, kanti izinto zokusetshenziswa zonke ziyi-polypropylene, kodwa inqubo yokukhiqiza ihlukile. Phakathi kwazo, ububanzi be-fiber bengqimba eboshiwe nge-spun ezinhlangothini zangaphakathi nezangaphandle bubukhulu, cishe ama-microns angu-20; ububanzi be-fibre ecibilikisiwe engqimbeni ephakathi bungama-micron amabili kuphela, eyenziwe ngezinto ze-polypropylene ezibizwa ngokuthi i-high-melt fat fiber. Ibuthakathaka futhi ayikwazi ukugezwa ngamanzi noma ifuthwe ngotshwala. Ngisho noma imanzi futhi yomile, izolimaza izicubu ze-fibre futhi ibangele izikhala. Uma amagciwane engena ngezikhala, imaski ilahlekelwa amandla ayo okuvikela.

Njengoba isimo esibucayi sesimo samanje sobhubhane, imaski isibe yinto ebalulekile empilweni yethu yokuhamba. Ake siqonde ukuthi kungani imaski ingavimbela amagciwane? Okokuqala, umthamo we-coronavirus ungama-80～120nm, ngoba uvame ukunamathela oketshezini lomzimba bese ufuthwa. , Ngakho-ke ngokuvamile mkhulu kuno-0.1um (0.1 micron (um) = 100 nanometers (nm)). Indwangu encibilikisiwe isebenzisa i-polypropylene njengezinto ezisetshenziswayo eziyinhloko, kanti ububanzi befayibha bungafinyelela ku-0.5-10um. Uma kuyigciwane elinamathele oketshezini lomzimba, lingahlungwa.

Ngalesi singeniso esingenhla, ingabe wazi okwengeziwe ngamamaski?

Ukuze uthole ulwazi lochwepheshe kanye nokubonisana mayelanaIndwangu Engalukiwe Eqhunyisiwe Encibilikisiwe, Umkhiqizo Oqediwe Ongalukiwe, Indwangu Engalukiwe ye-Spunlace, Hlunga Indwangu Engalukiwe, Okungalukiwe Okubhajwe Ngenaliti Engaphothiwe, wamukelekile ukuxhumana ne-Jin Haocheng Indwangu Engalukwanga. Sizokwenza konke okusemandleni ethu ukukusiza.
