Iindaba-TPU Base Film Processing Technology

Yintoni i-TPU Base Film?

Ifilimu ye-TPU yifilimu eyenziwe ngeegranule ze-TPU ngeenkqubo ezikhethekileyo ezifana ne-calendering, ukuphosa, ukuvuthela ifilimu, kunye nokwaleka. Ngenxa yokuba ifilimu ye-TPU ineempawu zokungena kwamanzi aphezulu, ukunyanzeliswa komoya, ukumelana nokubanda, ukumelana nobushushu, ukumelana nokunxiba, uxinzelelo oluphezulu, amandla okutsala aphezulu, kunye nenkxaso yomthwalo ophezulu, ukusetyenziswa kwayo kubanzi kakhulu, kwaye ifilimu yeTPU inokufumaneka kuzo zonke iinkalo. bobomi bemihla ngemihla. Ngokomzekelo, iifilimu ze-TPU zisetyenziselwa izinto zokupakisha, iintente zeplastiki, i-bladders yamanzi, imithwalo yempahla edibeneyo, njl njl. Okwangoku, iifilimu ze-TPU zisetyenziswa kakhulu kwiifilimu zokukhusela ipende kwintsimi yeemoto.

Ukusuka kwimbono yesakhiwo, ifilimu yokukhusela ipeyinti ye-TPU ikakhulu iqulunqwe ngokutyabeka okusebenzayo, ifilimu yesiseko se-TPU kunye nomgangatho wokunamathela. Phakathi kwabo, ifilimu yesiseko se-TPU yinxalenye ephambili yePPF, kwaye umgangatho wayo ubaluleke kakhulu, kwaye iimfuno zayo zokusebenza ziphezulu kakhulu.

Ngaba uyayazi inkqubo yemveliso yeTPU?

Ukutshatyalaliswa kunye nokumisa: i-molecular sieve dehumidification desiccant, ngaphezu kwe-4h, umswakama <0.01%

Ubushushu benkqubo: bhekisa kubenzi bezinto ezikrwada abacetyiswayo, ngokobunzima, useto lweMFI

Ukuhluzwa: landela umjikelo wokusetyenziswa, ukuthintela amabala amnyama ezinto zangaphandle

Impompo enyibilikayo: ukuzinzisa umthamo we-extrusion, ukulawulwa kwe-loop evaliweyo kunye ne-extruder

Screw: Khetha ubume bokucheba obusezantsi beTPU.

Intloko yokufa: yila umjelo wokuhamba ngokwe-rheology yezinto ze-TPU ze-aliphatic.

Inyathelo ngalinye libalulekile kwimveliso yePPF.

Eli nani lichaza ngokufutshane yonke inkqubo yokusetyenzwa kwe-aliphatic thermoplastic polyurethane ukusuka kwigranular masterbatch ukuya kwifilimu. Ibandakanya i-formula yokuxuba izinto kunye ne-dehumidification kunye nenkqubo yokomisa, eshushu, i-shears kunye ne-plasticizes particles eqinile kwi-melting (i-melting). Emva kokucoca kunye nokulinganisa, ukufa okuzenzekelayo kusetyenziselwa ukubumba, ukupholisa, ukulingana ne-PET, kunye nokulinganisa ubukhulu.

Ngokuqhelekileyo, umlinganiselo wobukhulu be-X-reyi usetyenziswa, kunye nenkqubo yokulawula eyimfihlo enempendulo engalunganga evela kwintloko yokufa okuzenzekelayo isetyenziswa. Ekugqibeleni, ukusika edge kuyenziwa. Emva kokuhlolwa kwesiphene, abahloli bekhwalithi bahlola ifilimu kwii-angles ezahlukeneyo ukuze babone ukuba iipropati ezibonakalayo ziyahlangabezana neemfuno. Ekugqibeleni, imiqulu iyasongwa kwaye inikezelwe kubathengi, kwaye kukho inkqubo yokuvuthwa phakathi.

Amanqaku eteknoloji yokucubungula

I-TPU masterbatch: I-TPU masterbatch emva kobushushu obuphezulu

umatshini wokulahla;

ifilimu yeTPU;

I-gluing yomatshini wokugubungela: I-TPU ifakwe kwi-thermosetting / i-light-setting machine kwaye ifakwe ngoluhlu lweglue ye-acrylic / iglue yokukhanya;

I-Laminating: I-Laminating ifilimu yokukhululwa kwe-PET kunye ne-TPU edibeneyo;

I-Coating (i-functional layer): i-nano-hydrophobic coating kwi-TPU emva kokutshatyalaliswa;

Ukomisa: ukomisa iglue kwifilimu kunye nenkqubo yokumisa ehamba nomatshini wokugubungela; le nkqubo izakuvelisa irhasi encinci yenkunkuma ephilayo;

I-Slitting: Ngokweemfuno zomyalelo, ifilimu edibeneyo iya kunqunyulwa ngobukhulu obuhlukeneyo ngumatshini wokuqhawula; le nkqubo iya kuvelisa imiphetho kunye neekona;

Ukuqengqeleka: ifilimu yokutshintsha umbala emva kokuba i-slitting ihlanjululwe kwiimveliso;

Ukupakishwa kwemveliso egqityiweyo: ukupakisha imveliso kwindawo yokugcina impahla.
