Kusukela ekuseni kwekhulu lama-21, intuthukoindwangu engalukiwe eqhumayoemhlabeni wonke, intuthuko iye yathuthuka ngesivinini esikhulu.
I-Hills Company kanye ne-Nordson Company yase-United States baphumelele ukuthuthukisa ubuchwepheshe be-meltblown obunezici ezimbili ngaphambili, okuhlanganisa uhlobo lwesikhumba, uhlobo oluseceleni, unxantathu, njll., ngokuvamile ubuncane befayibha bucishe bube yi-2 & micro;, inani lemigodi nge-intshi ngayinye yezinto ezijikelezayo ze-meltblown lingafinyelela emigodini eyi-100, ivolumu yokukhipha yembobo ngayinye ingafinyelela ku-0.5 g/min.

Indwangu Engalukiwe E-MeltblownOkwe-N95 99 Mask | JINHAOCHENG

Uhlobo lwesikhumba-umongo Ingenza indwangu engalukiwe izwakale ithambile futhi ingenziwa ibe yimikhiqizo eqondile, engavamile futhi ehlelekile ngokukhethekile. Ngokuvamile, kusetshenziswa izinto ezishibhile njengemongo, kanti ama-polymer ayigugu anamaphasela akhethekile noma aceliwe ayizingqimba zesikhumba sangaphandle. Isibonelo, umongo yi-polypropylene, kanti isikhumba sangaphandle siyi-nylon ukwenza i-fiber ibe yi-hygroscopic; i-Melting point polyethylene noma i-modified polypropylene, i-modified polyester, njll. Kuma-filaments e-carbon black conductive, umongo we-conductive ugoqwa ngaphandle.
Uhlobo oluseceleni lungenza indwangu engalukiwe ibe nokuthamba okuhle. Ngokuvamile yenziwe ngama-polymer amabili ahlukene, noma i-polymer efanayo enobukhulu obuhlukile. Ama-filaments azungezwe nge-spiral. Isibonelo, i-3M Company ithuthukise indwangu engalukiwe ye-PET/PP bicomponent filaments encibilikisiwe. Ngenxa yokulahlekelwa okuhlukile, kwakheka i-helical crimp, okwenza indwangu engalukiwe ibe nokuthamba okuhle kakhulu.

Uhlobo lwethiphu Lokhu kwenzelwa ukuhlanganisa enye i-polymer ohlotsheni lwe-trilobal, uhlobo oluphambene kanye nethiphu. Isibonelo, lapho kwenziwa ama-filaments aphikisanayo, aqhuba umswakama, kanye nalawo aqhuba umswakama, i-polymer eqhuba umswakama ingahlanganiswa ethekwini, engakwazi ukuqhuba umswakama futhi iqhube ugesi, i-antistatic, futhi igcine inani le-polymer eqhuba umswakama.
Uhlobo lwe-micro-denier Amamojula aqhekeka ngombala ophuzi, amise okwemigqa, noma amamojula e-ocean-islet angasetshenziswa. Ama-polymer amabili angavumelani ahlanganiswa ukuze kwenziwe ama-fiber webs amahle kakhulu, noma empeleni ama-nanofiber webs, afana nama-filament ahlanganisiwe athuthukiswe nguKimberly-Clark, okuyi-filament ahlanganisiwe enziwe ngama-polymers amabili angavumelani. Ngaphansi kwesekhondi lama-filament element emanzini ashisayo, ama-polymer amabili angahlanganiswa ngokuphelele ukuze akhe i-microfiber web. Uhlobo lwe-islet ludinga ukuncibilikisa ulwandle ukuze kutholakale inethiwekhi ye-islet fiber enhle.

Uhlobo lwe-mongrel Luyi-fiber web ehlanganisa izinto ezahlukene, imibala ehlukene, imicu ehlukene, izimo ezahlukene ezinqamula izinhlangothi, futhi empeleni ne-filaments yesikhumba, kokubili imicu ehlanganisiwe kanye ne-bicomponent, ukuze imicu ibe namaphasela adingekayo. Uma kuqhathaniswa nemikhiqizo ye-fibre ejwayelekile encibilikisiwe, lolu hlobo lwendwangu ye-bicomponent encibilikisiwe noma indwangu ye-fiber exubile engalukiwe ingathuthukisa kakhulu ukuhlungwa kwe-sludge medium, futhi yenze i-sludge medium ibe ne-antistatic, electrical conductivity, i-hygroscopicity, ithuthukise amaphasela e-hedge, njll. noma ithuthukise ukuhlangana, i-voluminousness kanye nokuvuleka komoya kwe-fiber web.

Izintambo ezincibilikisiwe ezinezici ezimbili zinganciphisa ukusebenza kwe-polymer eyodwa. Isibonelo, i-polypropylene ishibhile impela, kodwa uma isetshenziswa ezicini zezokwelapha, ayimelani nemisebe. Ngale ndlela, i-polypropylene ingasetshenziswa njengengqikithi futhi kungabizwa i-subcaste yangaphandle esebenzayo. Inkinga yokumelana nemisebe ingaphendulwa ngokubopha i-polymer engamelani nemisebe ngaphandle. Ngaleyo ndlela, umkhiqizo ungenziwa ube yintengo ephansi futhi ungahlangabezana nezimo zokusebenza, ezifana nezishintshi zokushisa nomswakama ezingasetshenziswa ohlelweni lokuphefumula emkhakheni wezokwelapha, futhi unganikeza ukushisa nomswakama ofanele wemvelo. Ulula, uyalahlwa noma kulula ukuwusika, uyathengeka, futhi usebenza njengodaka olusha ukususa ukungcola. Uqukethe ama-web amabili axubene kancane e-bicomponent meltblown. Usebenzisa i-fibre ye-bicomponent ye-jacket-core, ingqikithi yi-polypropylene, kanti isikhumba siyi-nylon. Ama-filament anezingxenye ezimbili angasebenzisa nezingxenye ezihlukile ezihlelwe ngendlela ekhethekile, ezifana ne-trilobal kanye ne-multi-lobed, ukwenza indawo yobuso ibe nkulu, futhi ngesikhathi esifanayo, ama-polymer angenza ngcono ukusebenza kokuhlunga angasetshenziswa endaweni engaphansi kobuso noma engxenyeni yesihloko. Ama-fiber web e-Olefin noma e-polyester meltblown bicomponent angenziwa abe yi-spherical liquid kanye negesi. I-mesh ye-fiber enezingxenye ezimbili encibilikisiwe ingasetshenziswa futhi entweni ye-sludge kagwayi; sebenzisa umphumela we-wicking ukwenza umongo odonsa indatshana wezinga eliphezulu; induku ye-wicking yokugcina uketshezi kanye nokufakwa, njll.
