Okungalukiwe okuphuphunyezwe ukuncibilikainqubo: ukondla nge-polymer - ukukhishwa okuncibilikisiwe - ukwakheka kwefayibha - ukupholisa - kunethiwekhi - ukuqinisa kube yindwangu.
Ukuthuthukiswa kobuchwepheshe be-melt-Jet nonwovens -- Ubuchwepheshe be-melt-jet obunezingxenye ezimbili
Kusukela ngekhulu lama-21, intuthuko yobuchwepheshe be-melt-jet nonwovens emhlabeni iye yathuthuka kakhulu.
Umgogodla wesikhwama:
Ingenza izinto ezingezona ezelukiwe zizizwe zithambile, ingenziwa imikhiqizo eqondile, engavamile, enomumo okhethekile. Ngokuvamile, umongo wenziwe ngezinto ezishibhile, kanti i-polymer ebizayo enezakhiwo ezikhethekile noma ezidingekayo ungqimba lwangaphandle, njenge-polypropylene core kanye ne-nylon yangaphandle ungqimba lwangaphandle ukuze kwenziwe i-fiber ibe yi-hygroscopic. Umongo uyi-polypropylene, kanti isikhumba sangaphandle singanamathela i-polyethylene ephansi yokuncibilika noma i-polypropylene eguquliwe, i-polyester eguquliwe, njll. Nge-fiber eqhubayo emnyama yekhabhoni, umongo oqhubayo ugoqwe kuwo.
Uhlobo lokuhlangana:
Ama-Nonwoven anokunwebeka okuhle ngokuvamile enziwa ngama-polymer amabili ahlukene noma i-polymer efanayo ene-viscosities ehlukene ibe yi-fiber enezingxenye ezimbili ezifanayo. Ukuncipha okuhlukile kokushisa kwama-polymer ahlukene kungasetshenziswa ukwenza imicu egoqekile ngokujikajika. Isibonelo, inkampani ye-3M yathuthukisa ama-nonwoven e-PET/PP anezingxenye ezimbili ancibilikisiwe. Ngenxa yokuncipha okuhlukile, ama-nonwoven akha i-spiral crimp, okwenza ama-nonwoven abe nokunwebeka okuhle kakhulu.
Uhlobo lwetheminali:
Lokhu kungokwezinhlobo ezintathu zamaqabunga, uhlobo oluphambene kanye nenhlanganisela yokugcina, uhlobo oluthile lwe-polymer, njenge-antistatic, umswakama, i-fibre conductive ingaba phezulu kwe-polymer conductive conductive, hhayi nje kuphela engaba yi-conductive, conductive, antistatic, futhi igcine inani le-polymer conductive.
Uhlobo lwe-Microdenier:
Kungasetshenziswa ukuma kwe-petal e-orenji, ingxenye yohlobo lwe-strip strip, futhi ingaba yingxenye yohlobo lwe-sea island. Ukusebenzisa ama-polymer amabili angahambisani ukuze kuhlungwe ukwenza inethiwekhi ye-superfine fiber, noma ngisho nenethiwekhi ye-nanofiber, njenge-fiber ka-kimberly-Clark's strip-type two-component, kuyinethiwekhi ye-fiber enhle kakhulu esebenzisa iqiniso lokuthi i-fiber enezingxenye ezimbili eyenziwe ngama-polymer amabili angahambisani ingahlungwa ngokuphelele ngaphansi komzuzwana emanzini ashisayo. Uhlobo lwe-sea-island luzoncibilikisa ulwandle ukuze kutholakale inethiwekhi enhle yezintambo ze-island.
I-hybrid:
Kuyinethiwekhi yezintambo ezinezinto ezahlukene, imibala ehlukene, imicu ehlukene, izimo ezahlukene zesigaba esiphambeneyo, ngisho nengaphakathi lesikhumba elixutshwe nemicu ejikelezayo kanye nemicu enezingxenye ezimbili, ukuze imicu ibe nazo zonke izinhlobo zezakhiwo ezidingekayo. Lolu hlobo lwe-melt-jet two-component fiber nonwovens noma i-mixed fiber nonwovens lungathuthukisa kakhulu i-filtering property ye-filter medium uma iqhathaniswa nemikhiqizo ye-melt-jet fiber ejwayelekile, futhi lenze i-filter medium ibe ne-antistatic property, i-electrical conductivity, i-hygroscopic property, i-enhanced barrier property, njll. Noma yenza i-fiber mesh bond, i-fluffy, i-air permeability ithuthuke.
I-fibre ye-shotcrete encibilikisiwe enezingxenye ezimbili ingangezelela ukuntuleka kokusebenza kwe-polymer eyodwa, njenge-polypropylene ishibhile kakhulu, kodwa ezintweni zokwelapha, ayimelani nokuchayeka emisebeni, ngakho-ke ingaba yi-polypropylene njengengaphakathi, engxenyeni yayo yangaphandle ukukhetha i-polymer emelene nemisebe efanele egoqwe ngaphandle ingaxazulula inkinga yokumelana nemisebe. Ngakho-ke, umkhiqizo ungaba oshibhile futhi uhlangabezane nezidingo zokusebenza, njengezishintshi zokushisa nomswakama zesistimu yokuphefumula emkhakheni wezokwelapha, ezinganikeza ukushisa kwemvelo kanye nomswakama ofanele. Inesisindo esincane, ilahlwa noma kulula ukuyibulala, ishibhile, kodwa futhi ingadlala indima eyengeziwe yokususa isihlungi sokungcola. Ingakhiwa inethiwekhi ye-fiber ye-melt-spray enezingxenye ezimbili ezixutshwe ngokulinganayo.
I-fiber yesikhumba yohlobo lwe-core ezimbili iyasetshenziswa, i-core yi-polypropylene kanti i-cortex iyi-nylon. I-fiber enezingxenye ezimbili ingakhiwa ngesigaba esikhethekile, njengesimo samaqabunga amathathu noma isimo samaqabunga amaningi, ukuze indawo yabo engaphezulu ibe nkulu. Okwamanje, ama-polymer angathuthukisa ukusebenza kokuhlunga angasetshenziswa futhi engqimbeni yobuso noma engxenyeni ye-tip ye-fiber. I-alkene noma i-polyester fusible spray enezingxenye ezimbili ye-fiber mesh ingenziwa ibe yizihlungi zoketshezi negesi. Inethi ye-fiber enezingxenye ezimbili ye-fibre ye-melting spray ingasetshenziswa futhi njenge-tip ye-cigarette filter; Umphumela wokudonsa oyinhloko usetshenziselwa ukwenza i-core ye-inki yezinga eliphezulu. Induku yokudonsa oyinhloko yokugcina uketshezi kanye nokufakwa, njll.
Ukuthuthukiswa kobuchwepheshe be-melt blown nonwovens -- i-melt blown nanofibers
Ukuze kwenziwe ama-nanofiber, izimbobo ze-spinneret zincane kakhulu kunalezo ezitholakala emishinini evamile yokujova i-melt. I-NTI ingaba yincane njenge-0.0635 mm (okungukuthi ama-microns angu-63.5) noma ibe yincane njenge-0.0025 ft. Amaphaneli e-spinneret e-Modular angahlanganiswa abe ububanzi obungaphezu kwamamitha amathathu. Ububanzi be-fibre yokufutha encibilikisiwe ngaleyo ndlela bungaba ngama-nanometer angu-500. Imicu eyodwa emihle kakhulu ingaba ngama-nanometer angu-200 ububanzi.
Njengoba imishini yokuncibilikisa nokufutha yama-nanofibers okuphotha inezimbobo ezincane zangasese, uma kungekho zinyathelo ezithathwayo, umphumela uzoncishiswa kakhulu. Ngakho-ke, i-NTI isebenzisa indlela yokwandisa inani lezimbobo zangasese, futhi ipuleti ngalinye le-spinneret linemigqa emi-3 noma ngaphezulu yemigodi yangasese. Ngokuhlanganisa inani lezingxenye zamayunithi (kuye ngobubanzi), isivuno ngesikhathi sokuphotha singanda kakhulu. Isimo sangempela ukuthi lapho kusetshenziswa izimbobo ezingama-micron angu-63.5, inani lezimbobo emgqeni owodwa wama-spinnerets ngemitha lingu-2880. Uma kusetshenziswa imigqa emithathu, inani lezimbobo emgqeni owodwa wama-spinnerets ngemitha lingafinyelela ku-8640, ukuze umphumela uqhathaniswe nowokuphotha i-shotcrete fiber evamile encibilikisiwe.
Ngenxa yokuthi ama-spinneret amancane anezimbobo ezixinene kakhulu ayabiza futhi avame ukuqhekeka (ukuqhekeka ngaphansi kokucindezeleka okuphezulu), izinkampani zithuthukise amasu amasha okubopha ukuze kuthuthukiswe ukushesha kwama-spinneret nokuvimbela ukuvuza ngaphansi kokucindezeleka okuphezulu.
I-fibre efuthwe nge-nanometer ingasetshenziswa njengendlela yokuhlunga, okungathuthukisa ukusebenza kahle kokuhlunga kakhulu. Kukhona futhi idatha ekhombisa ukuthi ngenxa yokuthi i-fibre ekwi-nanometer melt-jet nonwovens incane, indwangu ye-melt-jet ingahlanganiswa nendwangu e-spunbonded enesisindo esilula segremu, esengamelana nokucindezela okufanayo kwekhanda lamanzi, kanye nemikhiqizo ye-SMS eyenziwe ngayo inganciphisa isilinganiso se-fibre ye-melt-jet.
Singabantuindwangu engalukiwe encibilikisiwe yemaski yobusoifektri, wamukelekile ukusibonisana ~
