Litaba - TPU Base Film Processing Technology

TPU Base Film ke eng?

Filimi ea TPU ke filimi e entsoeng ka li-granules tsa TPU ka mekhoa e khethehileng e kang calendering, casting, filimi le ho roala.Hobane filimi ea TPU e na le litšobotsi tsa ho kenella ha mongobo o phahameng, ho kenella ha moea, ho hanyetsa serame, ho hanyetsa mocheso, ho hanyetsa ho roala, tsitsipano e phahameng, matla a ho hula haholo, le tšehetso e phahameng ea mojaro, ts'ebeliso ea eona e pharaletseng haholo, 'me filimi ea TPU e ka fumanoa likarolong tsohle. tsa bophelo ba letsatsi le letsatsi.Ka mohlala, lifilimi tsa TPU li sebelisoa ka thepa ea ho paka, litente tsa polasetiki, li-bladders tsa metsi, masela a kopantsoeng a thoto, joalo-joalo Hona joale, lifilimi tsa TPU li sebelisoa haholo-holo lifiliming tsa tšireletso ea pente tšimong ea likoloi.

Ho ea ka pono ea sebopeho, filimi ea ts'ireletso ea pente ea TPU e entsoe haholo ka ho roala ka mokhoa o sebetsang, filimi ea motheo ea TPU le lesela le khomarelang.Har'a bona, filimi ea motheo ea TPU ke karolo ea mantlha ea PPF, 'me boleng ba eona bo bohlokoa haholo,' me litlhoko tsa eona tsa ts'ebetso li phahame haholo.

Na u tseba mokhoa oa tlhahiso ea TPU?

Ho fokotsa mongobo le ho omisa: molecular sieve dehumidification desiccant, ho feta 4h, mongobo <0.01%

Mocheso oa ts'ebetso: bua ka baetsi ba thepa e tala ba khothalelitsoeng, ho latela boima, litlhophiso tsa MFI

Filtration: latela potoloho ea ts'ebeliso, ho thibela matheba a matšo a taba ea kantle ho naha

Melt pump: botsitso ba molumo oa extrusion, taolo ea loop e koetsoeng ka extruder

Screw: Khetha sebopeho se tlase sa ho kuta bakeng sa TPU.

E-shoa hlooho: rala mocha oa phallo ho latela rheology ea lisebelisoa tsa aliphatic TPU.

Mohato o mong le o mong o bohlokoa tlhahisong ea PPF.

Palo ena e hlalosa ka bokhutšoanyane ts'ebetso eohle ea ho lokisa aliphatic thermoplastic polyurethane ho tloha granular masterbatch ho ea filiming.E kenyelletsa mokhoa oa ho kopanya oa thepa le tsamaiso ea dehumidification le ho omisa, e futhumatsang, e kuta le ho etsa polasetiki ea likaroloana tse tiileng hore li qhibilihe (ho qhibiliha).Kamora ho sefa le ho lekanya, lefu la othomathike le sebelisetsoa ho bopa, ho pholile, ho lekana PET, le ho lekanya botenya.

Ka kakaretso, ho sebelisoa tekanyo ea botenya ba X-ray, 'me ho sebelisoa mokhoa oa ho laola lekunutu o nang le maikutlo a fosahetseng a tsoang hloohong ea "automatic die".Qetellong, ho khaola ka bohale ho etsoa.Ka mor'a ho hlahloba sekoli, bahlahlobi ba boleng ba hlahloba filimi ho tloha mahlakoreng a sa tšoaneng ho bona hore na thepa ea 'mele e finyella litlhoko.Qetellong, meqolo e phuthoa ebe e fuoa bareki, 'me ho na le ts'ebetso ea kholo lipakeng.

Lintlha tsa theknoloji ea ho sebetsa

TPU masterbatch: TPU masterbatch kamora mocheso o phahameng

mochine oa khatiso;

filimi ea TPU;

Sekhomaretsi sa mochini oa ho roala: TPU e behiloe mochining oa thermosetting / o behang leseli 'me o koahetsoe ka lera la sekhomaretsi sa acrylic / sekhomaretsi se bobebe;

Laminating: Laminating ea PET e lokolla filimi ka TPU e khomaretsoeng;

Ho roala (lera le sebetsang): ho roala ha nano-hydrophobic ho TPU ka mor'a ho lamination;

Ho omisa: ho omisa sekhomaretsi filiming ka mokhoa oa ho omisa o tlang le mochine oa ho roala;ts'ebetso ena e tla hlahisa khase e nyane ea litšila tsa manyolo;

Slitting: Ho ea ka litlhoko tsa taelo, filimi e kopantsoeng e tla aroloa ka boholo bo fapaneng ka mochine oa ho senya;ts'ebetso ena e tla hlahisa likarolo le likhutlo;

Rolling: filimi ea phetoho ea 'mala ka mor'a hore ho betla ho kenngoa lihlahisoa;

Sehlahisoa se felileng: ho paka sehlahisoa ka har'a polokelo.
