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 zokunyuka komswakama ophezulu, ukunyanzeliswa komoya, ukumelana nokubanda, ukumelana nobushushu, ukuxhathisa ukunxiba, uxinzelelo oluphezulu, amandla okutsala aphezulu, kunye nenkxaso ephezulu yomthwalo, ukusetyenziswa kwayo kubanzi kakhulu, kwaye ifilimu ye-TPU inokufumaneka kuzo zonke iinkalo zobomi 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 iqulunqwe ikakhulu ngokutyabeka okusebenzayo, ifilimu yesiseko se-TPU kunye ne-adhesive layer. 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 wokuphosa;

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.
