Nanofiber Membrane Replace Melt-Blown Fabric Mask Material

Chigoba Chosefera Zinthu Zosefera Nanofiber Membrane

Nembanemba ya nanofiber yogwira ntchito yozungulira ndi electrostatic ili ndi mainchesi ang'onoang'ono, pafupifupi 100-300 nm, Ili ndi mawonekedwe a kulemera kopepuka, malo akuluakulu pamwamba, malo otseguka pang'ono komanso mpweya wabwino wolowera ndi zina zotero. Tiyeni tizindikire mafyuluta olondola mu fyuluta ya mpweya ndi madzi, chitetezo chapadera, zida zodzitetezera zachipatala, zida zolondola zogwirira ntchito ya aseptic ndi zina zotero, Zipangizo zosinthira zamakono sizingafanane nazo ngati malo otseguka pang'ono.

Ma nanofiber membranes aonekera ngati chinthu chatsopano, ndipo amagwiritsidwa ntchito m'njira zosiyanasiyana m'maphunziro olekanitsa ma membranes. Popeza kale anali ogulitsidwa kale kuti agwiritsidwe ntchito posefa mpweya, zinthu za nanofibers zaganiziridwa posachedwapa kuti zigwiritsidwe ntchito polekanitsa madzi, makamaka poyeretsa madzi, chifukwa cha kukula kwake kochepa komanso kokhazikika kwa ma pore, komanso kukana kwa hydraulic kochepa komwe kumachokera ku ma poresity apamwamba. Kuphatikiza apo, malo okwera kwambiri a zinthuzi amathandiza kuti zigwiritsidwe ntchito poletsa ma adsorption.

Ubwino wa nembanemba ya Nanofiber

Msika wamakono wa zigoba ndi thonje losalukidwa komanso losungunuka, losalukidwa pafupifupi 20μm, Thonje losungunuka ndi pafupifupi 1-5μm. Chitseko cha nembanemba ya nanofiber chikhoza kukhala 100-300 nanometers.

Kuyerekeza ndi nsalu yosungunuka ndi zinthu zina

Nsalu yosungunuka imagwiritsidwa ntchito kwambiri pamsika wamakono, Ndi ulusi wa PP polymeric womwe umasungunuka kutentha kwambiri, m'mimba mwake ndi pafupifupi 1 ~ 5μm.

Kachidutswa ka nanofiber komwe kamapangidwa ndi Shandong Blue future, m'mimba mwake ndi 100-300nm (nanometer)

Kuyerekeza mfundo zosefera ndi kupirira kokhazikika

Nsalu yosungunuka yomwe ikugulitsidwa pamsika wamakono, kuti ipange zotsatira zabwino zosefera, imafunika kulowetsedwa kwa electrostatic, zinthuzo zimagawidwa ndi electrostatic electret, yokhala ndi mphamvu yokhazikika. Kuti zitheke kusefera bwino, mphamvu zochepa zotsutsana ndi kusefera. Koma mphamvu ya electrostatic ndi mphamvu zosefera zidzakhudzidwa kwambiri ndi chinyezi cha kutentha. Mphamvu idzachepa ndi kutha pakapita nthawi. Kusowa kwa mphamvu kumapangitsa kuti tinthu tomwe timayamwa ndi nsalu yosungunuka tidutse mu nsalu yosungunuka. Mphamvu yoteteza si yokhazikika ndipo nthawi ndi yochepa.

Nembanemba ya Shandong Blue future ndi yosiyana ndi ya Shandong Blue future, siili ndi mphamvu iliyonse chifukwa cha mphamvu ndi chilengedwe. Patulani zinthu zodetsa pamwamba pa nembanemba. Chitetezo chake chimakhala chokhazikika ndipo nthawi yake ndi yayitali.

Kuyerekeza ndi zinthu zina ndi kuchuluka kwa kutayikira

Chifukwa cha ukadaulo wokonza nsalu yosungunuka ndi kutentha kwambiri, n'zovuta kuwonjezera ntchito zina ku nsalu yosungunuka, komanso sizingatheke kuwonjezera mphamvu zowononga tizilombo toyambitsa matenda kudzera mu kukonza pambuyo pake. Popeza mphamvu zamagetsi za nsalu yosungunuka zimachepa kwambiri panthawi yodzaza mankhwala opha tizilombo toyambitsa matenda, ilo lilibe ntchito yothira madzi.

Ntchito yoletsa mabakiteriya komanso yoletsa kutupa ya zinthu zosefera pamsika, ntchitoyo imawonjezeredwa pa zinthu zina zonyamulira. Zinthu zonyamulirazi zili ndi malo otseguka akuluakulu, mabakiteriya amaphedwa ndi kugundana, zinthu zodetsa zomwe sizikupezeka zomwe zimamangiriridwa ku nsalu yosungunuka ndi mphamvu yosasunthika. Mabakiteriya amapitirizabe kukhala ndi moyo pambuyo poti mphamvu yosasunthika yatha, kudzera mu nsalu yosungunuka, ntchito yoletsa mabakiteriya imachepa kwambiri, ndipo kuchuluka kwa zinthu zodetsa kumakhala kwakukulu.

Nembanemba ya nanofiber imapangidwa pansi pa kutentha kochepa, ndikosavuta kuwonjezera zinthu zogwira ntchito komanso mankhwala opha mabakiteriya. Kutuluka kwa madzi kumakhala kochepa.

Chigoba cha nano chakhala chigoba choteteza bwino chifukwa cha ntchito yake yosefera kwambiri. Kupatula thonje losungunuka, zizindikiro za nano anti-bacterial, zimawonjezeranso kabowo kakang'ono ka 100-300 nanofiber nembanemba. Pamwamba pake pali kapangidwe ka microporous kofanana ndi ukonde, komwe kumakhala ndi kusintha kovuta kwambiri mu kapangidwe ka magawo atatu monga kulumikizana kwa netiweki, kuyika mabowo ndi kupindika kwa njira, kotero kali ndi ntchito yabwino kwambiri yosefera pamwamba. Chigoba cha nanofiber chopangidwa ndi zinthuzi chili ndi mawonekedwe a ntchito yotchinga kwambiri, moyo wautali, woonda komanso wopumira, ndipo chimapeza kusefera kolondola kwambiri, komwe kumathetsa zovuta za fyuluta yamakono: kuyamwa kwa mphamvu kwa thonje losungunuka kumasiyana malinga ndi nthawi ndi malo, ndipo ntchito yosefera imachepa. Ndipo imatha kulumikizidwa ku ntchito yoletsa mabakiteriya mwachindunji, kuthetsa vuto la kuchuluka kwa mabakiteriya omwe amatuluka m'zinthu zotsutsana ndi mabakiteriya pamsika wamakono.

Njira yatsopano yopangira chigoba mtsogolo ndi yothandiza kwambiri komanso yodzitetezera. Ndi njira yatsopano yopewera miliri.
