Kusetyenzwa lwefilimu, olunye uhlobo lwemathiriyeli ekrwada lukhutshelwa kolunye uhlobo lwefilimu eyenziweyo okanye kwiindidi ezahlukeneyo zeefilimu ezenziweyo kunye nokuncamatheliswa kusetyenziselwa ukudibanisa ukwenza iifilimu zamanqanaba amaninzi.Le mveliso ibizwa ngokuba ziifilimu ezihlanganisiweyo.Co-extruded filmineempawu ezininzi zefilimu edibeneyo, kodwa kukho umehluko omnye, oko kukuthi, zonke iileya zefilimu edibeneyo zikhutshwe ngexesha elifanayo, kwaye iileyile zibophelelwe ngokunyibilika okutshisayo ngaphandle kwenkqubo yokucoca.
Izinto zefilimu edibeneyo ziyiplastiki, kodwa iphepha, i-foil yensimbi (ngokuqhelekileyo i-aluminium) okanye ilaphu linokusetyenziswa.Zonke iileya zeifilimu edibeneyozikhutshwe ngexesha elifanayo, ngoko ke akuyi kubakho i-aluminium foil, iphepha kunye nezinye izinto ezingekho zeplastiki.
I-Multi-layer co-extrusion barrier membrane yifilimu edibeneyo esebenzayoeyenziwe ngokusebenzisa ii-extruders ezininzi ukukhupha i-resin kunye nokusebenza komqobo ophezulu kunye nokunyibilika kwezinye iirasi ngokufa okuqhelekileyo.I-Multi-layer co-extrusion composite yinkqubo yemveliso edibeneyo eluhlaza, ngakumbi kwishishini langoku lokupakisha ukutya, izinto ezisetyenziswayo ziqhelekile zizixhobo eziqinisekiswe yi-United States ye-Arhente yoKutya kunye neMpilo kunye noKhuseleko, kwaye izinto eziluhlaza zinikezelwa ngokufanayo kumntu ngamnye. umaleko ngombhobho okhethekileyo wothutho.Akukho luvezo lwemathiriyeli ekrwada kunye nongcoliseko lokusingqongileyo kwinkqubo yokucubungula.Umaleko wayo oqukumbelayo wenziwe nge-LLDPE eguquliweyo njengento ekrwada, engeyiyo ityhefu kokusingqongileyo, ukutya kunye nomzimba womntu kwaye ayiyi kubonakala i-compound yendabuko eyomileyo, oko kukuthi, into ebizwa ngokuba yi-solvent residue phenomenon, ngaphandle kokungcola kwegesi;Ikwahluke kwi-compounding eyomileyo, i-solvent-free compounding kunye nenkqubo yokudibanisa i-single-layer extrusion, kwaye ifuna i-oven yokomisa unyango, ngoko ukusetyenziswa kwamandla kuncinci.Ukongezelela, inkqubo ye-multi-layer co-extrusion composite nayo ineenzuzo ezilandelayo.
(1) Ixabiso eliphantsi le-multi-layer co-extrusion co-extrusion composite process isebenzisa iindidi zeerasi ezinemisebenzi eyahlukeneyo.Inye kuphela inkqubo yokubumba i-blow-molding ingasetyenziselwa ukwenza iimveliso zefilimu ezidibeneyo ezinemisebenzi emininzi, enokunciphisa iindleko zokuvelisa.Ukongeza, kunokunciphisa ukusebenza okufunekayo kwe-resin ekrwada ukuya kubukhulu obuncinci, kwaye ubuncinci bobukhulu bomgangatho omnye bunokufikelela kwi-2 ~ 3 μ m.Inokunciphisa kakhulu ukusetyenziswa kwe-resin ebiza kakhulu, ngaloo ndlela inciphisa iindleko zezinto eziphathekayo.
(2) Itekhnoloji ye-flexible multi-layer co-extrusion iyakwazi ukuhambelana nezixhobo ezahlukeneyo zokudibanisa kwiintlobo ezahlukeneyo ezisebenzisa ngokupheleleyo izinto eziluhlaza kunye neempawu ezahlukeneyo kunye nefom ngexesha elinye.Ayikhawulelwanga ziinkcukacha ezifanelekileyo zemveliso yemarike kwaye inokwanelisa ngokufanelekileyo iimfuno zezihlandlo ezahlukeneyo zokupakishwa.Okukhona iileya ezininzi, kokukhona ubhetyebhetye uyilo lwesakhiwo kunye neendleko eziphantsi.
(3) Ukusebenza okuphezulu kwenkqubo ye-co-extrusion composite idibanisa i-adhesive etyhidiweyo kunye nesiseko se-resin.Le nkqubo inamandla amaxolo aphezulu aqhele ukuya kuthi ga kwi-3N/15mm okanye ngaphezulu alungele imathiriyeli yokupakisha ngokubanzi.Kwiimveliso ezineemfuno eziphezulu zamandla e-peel, i-resin ye-thermosensitive inokongezwa kwi-composite.Ngeli xesha, amandla e-peel anokufikelela kwi-14N/15mm, okanye nangaphezulu.
(4) Iimveliso ezidityanisiweyo ezidityanisiweyo ezininzi zinokugubungela phantse zonke iindawo zokupakisha, kuquka ukutya, iimveliso zemichiza yemihla ngemihla, iziselo, amayeza, iifilimu ezikhuselayo kunye neemveliso ze-aerospace.Okwangoku, iimveliso ezininzi ezomileyo ezihlanganisiweyo e-China zamkele inkqubo ye-co-extrusion phesheya.Iityhubhu ze-toothpaste ezingenakuveliswa yinkqubo edibeneyo eyomileyo.Iphepha leplastiki yealuminiyam yeemveliso ezihlanganisiweyo.I-aerospace kunye nezinye iimveliso nazo zibonwa ngenkqubo ye-co-extrusion.Ngophando olunzulu kunye nokuhlaziywa okuqhubekayo kwe-coextrusion composite resin, iteknoloji kunye nezixhobo, i-multi-layer coextrusion composite iya kwandisa ukuya kuluhlu olubanzi.
