I-Spunbond ne-melt blown yizinqubo ezimbili ezihlukene zokukhiqiza indwangu engalukiwe, enomehluko omkhulu ezintweni ezingavuthiwe, izindlela zokucubungula, ukusebenza komkhiqizo, nezinkambu zokufaka isicelo.
Umgomo we-spunbond kanye nokuncibilika okushaywayo
I-Spunbond isho indwangu engalukiwe eyenziwe ngokukhipha izinto ze-polymer esimweni esincibilikisiwe, ifafaze into encibilikisiwe ku-rotor noma umlomo wombhobho, iyidonsele phansi endaweni encibilikisiwe futhi iyiqinise ngokushesha ukuze yakhe i-fibrous material, bese ixhuma futhi ihlanganise imicu nge-mesh noma i-electrostatics spinning. Umgomo uwukukhipha i-polymer encibilikisiwe nge-extruder, bese udlula ezinqubweni eziningi ezifana nokupholisa, ukwelula, nokwelula okuqondile, ekugcineni kwakheke indwangu engalukiwe.
I-Meltblown, ngakolunye uhlangothi, inqubo yokukhipha izinto ze-polymer endaweni encibilikisiwe ngokusebenzisa umlomo wombhobho wesivinini esikhulu. Ngenxa yomthelela nokupholisa kokugeleza komoya okunesivinini esikhulu, izinto ze-polymer ziqina ngokushesha zibe izinto ezinezintambo futhi zintante emoyeni, ezibe sezicutshungulwa ngokwemvelo noma ezimanzi ukuze zakhe inethiwekhi yefayibha ekahle yendwangu engalukiwe. Isimiso siwukufafaza izinto ze-polymer ezincibilikisiwe ezinezinga lokushisa eliphezulu, zelulwe zibe imicu emihle ngokugeleza komoya okunesivinini esikhulu, futhi ziqine ngokushesha zibe imikhiqizo evuthiwe emoyeni, kwakhe ungqimba lwempahla yendwangu ecolekile engalukiwe.
Izinto zokusetshenziswa ezihlukene
Izindwangu ezingezona ezilukiwe eziphothiwe ngokuvamile zisebenzisa imicu yamakhemikhali efana ne-polypropylene (PP) noma i-polyester (PET) njengezinto zokusetshenziswa, kuyilapho izindwangu ezingalukiwe ezincibilikayo zisebenzisa izinto ze-polymer esimweni esincibilikisiwe, njenge-polypropylene (PP) noma i-polyacrylonitrile (PAN).Izidingo zezinto zokusetshenziswa ziyahlukahluka. I-Spunbonding idinga i-PP ukuthi ibe ne-MF ka-20-40g/min, kuyilapho ukuncibilika kudinga u-400-1200g/min.
Ukuqhathaniswa phakathi kwemicu encibilikayo ephephethwayo namafiber we-spunbond
A. Ubude befayibha – i-spunbond njengefilament, incibilika ephephetheka njengefayibha emfushane
B. Amandla efayibha: Amandla efayibha e-spunbonded>Amandla efayibha encibilikisiwe
C. Fibre fineness: Ifayibha encibilikisiwe ingcono kune-spunbond fiber
Izindlela ezihlukene zokucubungula
Ukucutshungulwa kwendwangu engalukiwe ye-spunbond kuhlanganisa ukuncibilika kwemicu yamakhemikhali emazingeni okushisa aphezulu, ukuwadweba, bese kwakha isakhiwo senethiwekhi ye-fiber ngokupholisa nokwelula; Indwangu engalukiwe encibilikisiwe iyinqubo yokufafaza izinto ze-polymer ezincibilikisiwe emoyeni ngokusebenzisa umlomo wombhobho wesivinini esikhulu, ipholise ngokushesha futhi izelule ibe imicu emihle ngaphansi kwesenzo sokugeleza komoya okunesivinini esikhulu, ekugcineni yenze ungqimba lwesakhiwo senethiwekhi yefiber eminyene.
Esinye sezici zezindwangu ezingalukiwe ezincibilikisiwe ukuthi ukucoleka kwefayibha kuncane, ngokuvamile kungaphansi kuka-10nm (ama-micrometer), futhi imicu eminingi inobunono obuyi-1-4 rm.
Amandla ahlukahlukene kuwo wonke ulayini wokuphotha kusukela ku-nozzle ephehlwayo encibilikayo kuya kudivayisi eyamukelayo awakwazi ukulingana (ngenxa yokuguquguquka kwamandla aqinile wezinga lokushisa eliphezulu nesivinini esikhulu sokugeleza komoya, isivinini nezinga lokushisa lomoya opholileyo, njll.), okuholela ekulinganeni kwefayibha engalingani.
Ukufana kobubanzi befayibha kumeshi yendwangu engalukiwe ye-spunbond kungcono kakhulu kunemicu yesifutho, ngoba enqubweni ye-spunbond, izimo zenqubo yokuphotha zizinzile, futhi izinguquko ezimweni zokubhala nokupholisa zincane uma kuqhathaniswa.
Ukuphuphuma kokuphotha kuyahlukahluka. I-Melt blown spinning iphakeme ngo-50-80 ℃ kune-spunbond spinning.
Ijubane elinwebekayo lemicu liyahlukahluka. Ukudla okuphothayo okungu-6000m/min, kuncibilike kuphephethelwe ku-30Km/min.
UNgonyama welula ibanga lakhe kodwa wehluleka ukuzibamba. I-Spunbound 2-4m, ihlanganiswe ngo-10-30cm.
Izimo zokupholisa nokudonsa zihlukile. Amafayibha e-Spinnbond adonswa ngomoya obandayo ophozithivu/ongemuhle ku-16 ℃, kuyilapho amafuse evuthelwa ngomoya oshisayo/ongalungile eduze kuka-200 ℃.
Ukusebenza komkhiqizo okuhlukile
Izindwangu ezingalukiwe eziphothiwe zivame ukuba namandla aphezulu okuphuka kanye nobude, kodwa ukuthungwa nokufana kwe-fiber mesh kungase kube kubi, okuhlangabezana nezidingo zemikhiqizo esemfashinini njengezikhwama zokuthenga; Indwangu engalukiwe ephephethwa yincibilika inamandla okuphefumula kahle, icwenga, ukumelana nokugqokwa, kanye nezindawo ezilwa nokuqina, kodwa ingaba nokungezwani kahle kwesandla namandla, futhi ingasetshenziswa ukwenza imaski yezokwelapha neminye imikhiqizo.
Izinkambu zohlelo lokusebenza ezahlukene
Izindwangu ezingalukiwe eziphothiwe zisetshenziswa kakhulu kwezokwelapha, izingubo, ikhaya, izimboni neminye imikhakha, njengamamaski, izingubo zokuhlinza, izembozo zosofa, amakhethini, njll; Indwangu engalukiwe encibilikayo isetshenziswa ikakhulukazi kwezokwelapha, ezempilo, ukuvikela, ukuvikelwa kwemvelo kanye neminye imikhakha, njengamamaski asezingeni eliphezulu, izingubo zokuzivikela, izihlungi, njll.
Isiphetho
Indwangu engalukiwe ephephethwa yi-Melt kanye ne-spunbond engalukiwe izinto ezimbili ezihlukene ezingezona ezilukiwe ezinezinqubo nezici ezihlukene zokukhiqiza. Mayelana nokusetshenziswa kanye nokukhetha, kuyadingeka ukucubungulisisa izidingo zangempela kanye nezimo zokusetshenziswa, bese ukhetha impahla yendwangu engalukiwe efaneleke kakhulu.
