Izindaba - I-TPU Base Film Processing Technology

Iyini i-TPU Base Film?

Ifilimu ye-TPU ifilimu eyenziwe ngama-TPU ama-granules ngezinqubo ezikhethekile ezifana ne-calendering, ukusakaza, ukufutha kwefilimu, nokuhlanganisa.Ngenxa yokuthi ifilimu ye-TPU inezici zokungena komswakama ophezulu, ukungena komoya, ukumelana nokubanda, ukumelana nokushisa, ukumelana nokugqoka, ukushuba okuphezulu, amandla okudonsa aphezulu, nokusekelwa komthwalo ophezulu, ukusetshenziswa kwayo kubanzi kakhulu, futhi ifilimu ye-TPU ingatholakala kuzo zonke izici. yokuphila kwansuku zonke.Isibonelo, amafilimu e-TPU asetshenziselwa izinto zokupakisha, amatende epulasitiki, ama-bladders amanzi, izindwangu ezihlanganisiwe zemithwalo, njll. Njengamanje, amafilimu e-TPU asetshenziswa kakhulu kumafilimu okuvikela upende emkhakheni wezimoto.

Ngokombono wesakhiwo, ifilimu yokuvikela upende we-TPU ikakhulukazi yakhiwe ngokunamathela okusebenzayo, ifilimu eyisisekelo ye-TPU kanye nongqimba olunamathelayo.Phakathi kwazo, ifilimu eyisisekelo ye-TPU iyingxenye eyinhloko ye-PPF, futhi ikhwalithi yayo ibaluleke kakhulu, futhi izidingo zayo zokusebenza ziphezulu kakhulu.

Ingabe uyayazi inqubo yokukhiqiza ye-TPU?

Ukunciphisa umswakama nokomisa: i-molecular sieve dehumidification desiccant, ngaphezu kwe-4h, umswakama <0.01%

Ukushisa kwenqubo: bheka abakhiqizi bezinto ezingavuthiwe ezinconyiwe, ngokusho kobunzima, izilungiselelo ze-MFI

Ukuhlunga: landela umjikelezo wokusetshenziswa, ukuvimbela amabala amnyama wendaba yangaphandle

Iphampu ye-Melt: ukuzinza kwevolumu ye-extrusion, ukulawulwa kwe-loop evaliwe nge-extruder

Isikulufu: Khetha isakhiwo esiphansi sokugunda se-TPU.

Ikhanda lokufa: klama isiteshi sokugeleza ngokuvumelana ne-rheology yezinto ze-TPU ze-aliphatic.

Isinyathelo ngasinye sibalulekile ekukhiqizeni i-PPF.

Lesi sibalo sichaza kafushane yonke inqubo yokucubungula i-aliphatic thermoplastic polyurethane kusuka ku-granular masterbatch kuye kwifilimu.Kuhilela ukuxubana kwefomula yezinto kanye nesistimu yokususa umswakama kanye nokomisa, okushisisa, ukugunda futhi kufake ipulasitiki izinhlayiya eziqinile zibe zincibilika (zincibilike).Ngemuva kokuhlunga nokulinganisa, i-automatic die isetshenziselwa ukubumba, ukupholisa, ukulingana ne-PET, kanye nokulinganisa ukujiya.

Ngokuvamile, kusetshenziswa isilinganiso sobukhulu be-X-ray, futhi kusetshenziswa isistimu yokulawula eyimfihlo enempendulo engemihle evela ekhanda lokufa elizenzakalelayo.Ekugcineni, ukusika emaphethelweni kwenziwa.Ngemuva kokuhlolwa okungalungile, abahloli bekhwalithi bahlola ifilimu besuka ezinhlangothini ezahlukene ukuze babone ukuthi izakhiwo ezibonakalayo ziyahlangabezana yini nezidingo.Ekugcineni, ama-rolls ayagoqwa futhi anikezwe amakhasimende, futhi kukhona inqubo yokuvuthwa phakathi.

Ukucubungula amaphuzu wobuchwepheshe

I-TPU masterbatch: I-TPU masterbatch ngemuva kwezinga lokushisa eliphezulu

umshini wokuphonsa;

ifilimu ye-TPU;

I-gluing yomshini wokunamathisela: I-TPU ibekwe emshinini wokugcoba we-thermosetting / ukukhanya-setting futhi ihlanganiswe nongqimba lweglue ye-acrylic / iglue yokwelapha ukukhanya;

Laminating: Laminating the PET release film with the glued TPU;

I-Coating (ungqimba olusebenzayo): i-nano-hydrophobic coating ku-TPU ngemva kokuqothula;

Ukomisa: ukomisa i-glue efilimu ngenqubo yokumisa efika nomshini wokugcoba;le nqubo izokhiqiza inani elincane legesi yemfucuza yezinto eziphilayo;

Ukusika: Ngokwezidingo ze-oda, ifilimu eyinhlanganisela izonqunywa ngosayizi ohlukene ngomshini wokusika;le nqubo izokhiqiza imiphetho namakhona;

Ukugoqa: ifilimu yokushintsha umbala ngemuva kokusikwa ifakwe emikhiqizweni;

Ukupakishwa komkhiqizo okuqediwe: ukupakisha umkhiqizo endaweni yokugcina impahla.
