Nkhani - TPU Base Film Processing Technology

Kodi TPU Base Film ndi chiyani?

Kanema wa TPU ndi filimu yopangidwa kuchokera ku ma granules a TPU kudzera munjira zapadera monga kuwerengera, kuponya, kuwomba filimu, ndi zokutira. Chifukwa filimu ya TPU ili ndi mawonekedwe a chinyezi chapamwamba, kutsekemera kwa mpweya, kukana kuzizira, kukana kutentha, kukana kuvala, kuthamanga kwambiri, mphamvu yokoka kwambiri, ndi chithandizo chachikulu cha katundu, ntchito yake ndi yotakata kwambiri, ndipo filimu ya TPU imapezeka m'mbali zonse. za moyo watsiku ndi tsiku. Mwachitsanzo, mafilimu a TPU amagwiritsidwa ntchito popanga zida, mahema apulasitiki, chikhodzodzo cha madzi, nsalu zopangira katundu, ndi zina zotero. Pakalipano, mafilimu a TPU amagwiritsidwa ntchito makamaka mu mafilimu otetezera utoto m'munda wamagalimoto.

Kuchokera pamawonekedwe, filimu yoteteza utoto wa TPU imapangidwa makamaka ndi zokutira zogwira ntchito, filimu yoyambira ya TPU ndi zomatira. Pakati pawo, filimu yoyambira ya TPU ndiye chigawo chachikulu cha PPF, ndipo khalidwe lake ndilofunika kwambiri, ndipo zofunikira zake ndizokwera kwambiri.

Kodi mukudziwa momwe TPU imapangidwira?

Dehumidification ndi kuyanika: molecular sieve dehumidification desiccant, kuposa 4h, chinyezi <0.01%

Kutentha kwa njira: tchulani opanga zopangira zomwe akulimbikitsidwa, malinga ndi kuuma, zoikamo za MFI

Kusefera: Tsatirani kagwiritsidwe ntchito, kuti mupewe mawanga akuda azinthu zakunja

Sungunulani pampu: kukhazikika kwa voliyumu ya extrusion, kuwongolera kotsekeka ndi extruder

Screw: Sankhani mawonekedwe otsika ometa ubweya wa TPU.

Ifa mutu: pangani njira yotuluka molingana ndi rheology ya aliphatic TPU zakuthupi.

Gawo lirilonse ndilofunika kwambiri pakupanga PPF.

Chiwerengerochi chikufotokozera mwachidule njira yonse yopangira aliphatic thermoplastic polyurethane kuchokera ku granular masterbatch kupita ku filimu. Zimaphatikizapo kusakaniza chilinganizo cha zinthu ndi dehumidification ndi kuyanika dongosolo, amene heats, shears ndi plasticizes olimba particles kusungunuka (kusungunuka). Pambuyo kusefa ndi kuyeza, kufa kwadzidzidzi kumagwiritsidwa ntchito kuumba, kuziziritsa, kukwanira PET, ndikuyesa makulidwe.

Nthawi zambiri, muyeso wa makulidwe a X-ray umagwiritsidwa ntchito, ndipo njira yowongolera mwachinsinsi yokhala ndi malingaliro oyipa kuchokera kumutu wodziyimira pawokha imagwiritsidwa ntchito. Pomaliza, kudula m'mphepete kumachitika. Pambuyo poyang'anitsitsa zolakwika, oyang'anira khalidwe amayendera filimuyo kuchokera kumbali zosiyanasiyana kuti awone ngati katundu wakuthupi akukwaniritsa zofunikira. Pomaliza, mipukutuyo imakulungidwa ndikuperekedwa kwa makasitomala, ndipo pali njira yakukhwima pakati.

Processing mfundo zamakono

TPU masterbatch: TPU masterbatch pambuyo kutentha kwambiri

makina osindikizira;

filimu ya TPU;

Kupaka makina opangira makina: TPU imayikidwa pa makina opangira thermosetting / kuwala-woyika ndikukutidwa ndi guluu wa acrylic / kuwala-kuchiritsa guluu;

Laminating: Laminating PET kumasulidwa filimu ndi glued TPU;

Kupaka (wosanjikiza): zokutira za nano-hydrophobic pa TPU pambuyo pa kuyanika;

Kuyanika: kuyanika guluu pafilimuyo ndi kuyanika komwe kumabwera ndi makina opaka; njirayi adzapanga pang'ono mpweya zinyalala organic;

Kudula: Malingana ndi zofunikira za dongosolo, filimu yophatikizika idzadulidwa mosiyanasiyana ndi makina opangira; njirayi idzatulutsa m'mphepete ndi ngodya;

Kugubuduza: filimu yosintha mtundu pambuyo podulidwa imadulidwa kukhala zinthu;

Kutsirizitsa katundu: kulongedza katundu m'nyumba yosungiramo katundu.
