Kodi Filimu ya TPU Base ndi chiyani?

Filimu ya TPU ndi filimu yopangidwa kuchokera ku TPU granules kudzera mu njira zapadera monga kuyika calendering, casting, kupyoza filimu, ndi kupaka utoto. Chifukwa filimu ya TPU ili ndi mawonekedwe a kulowetsedwa kwa chinyezi chambiri, kulowetsedwa kwa mpweya, kukana kuzizira, kukana kutentha, kukana kutopa, kupsinjika kwakukulu, mphamvu yokoka kwambiri, komanso kuthandizira katundu wambiri, kugwiritsidwa ntchito kwake ndi kwakukulu kwambiri, ndipo filimu ya TPU imapezeka m'mbali zonse za moyo watsiku ndi tsiku. Mwachitsanzo, mafilimu a TPU amagwiritsidwa ntchito muzinthu zopakira, mahema apulasitiki, zikhomo zamadzi, nsalu zophatikizika za katundu, ndi zina zotero. Pakadali pano, mafilimu a TPU amagwiritsidwa ntchito kwambiri mumafilimu oteteza utoto m'munda wamagalimoto.

Kuchokera pamalingaliro a kapangidwe kake, filimu yoteteza utoto wa TPU imapangidwa makamaka ndi zokutira zogwira ntchito, filimu yoyambira ya TPU ndi guluu. Pakati pawo, filimu yoyambira ya TPU ndiye gawo lalikulu la PPF, ndipo ubwino wake ndi wofunikira kwambiri, ndipo magwiridwe ake ndi apamwamba kwambiri.

Kodi mukudziwa njira yopangira TPU?

Kuchotsa chinyezi ndi kuumitsa: molecular sieve desiccant desiccant, yoposa maola 4, chinyezi <0.01%

Kutentha kwa ndondomeko: onani zomwe opanga zinthu zopangira amalangiza, malinga ndi kuuma, makonda a MFI

Kusefa: kutsatira njira yogwiritsira ntchito, kuti mupewe mawanga akuda a zinthu zakunja

Pumpu yosungunuka: kukhazikika kwa voliyumu yotulutsa, kuwongolera kuzungulira kotsekedwa ndi chotulutsira

Chokulungira: Sankhani kapangidwe kocheperako ka TPU.

Mutu wa Die: pangani njira yoyendetsera madzi motsatira rheology ya zinthu za TPU za aliphatic.

Gawo lililonse ndi lofunika kwambiri pakupanga PPF.

Chithunzichi chikufotokoza mwachidule njira yonse yogwiritsira ntchito aliphatic thermoplastic polyurethane kuchokera ku granular masterbatch kupita ku filimu. Chimaphatikizapo njira yosakaniza zinthuzo ndi njira yochotsera chinyezi ndi kuumitsa, yomwe imatenthetsa, kudula ndi kusungunula tinthu tolimba kuti tisungunuke (kusungunuka). Pambuyo posefa ndi kuyeza, die yodziyimira yokha imagwiritsidwa ntchito kupanga, kuziziritsa, kuyika PET, ndi kuyeza makulidwe.

Kawirikawiri, kuyeza makulidwe a X-ray kumagwiritsidwa ntchito, ndipo njira yowongolera yachinsinsi yokhala ndi mayankho oipa kuchokera ku mutu wodziyimira pawokha imagwiritsidwa ntchito. Pomaliza, kudula m'mphepete kumachitika. Pambuyo poyang'ana zolakwika, oyang'anira khalidwe amawunika filimuyo kuchokera mbali zosiyanasiyana kuti awone ngati mawonekedwe ake akukwaniritsa zofunikira. Pomaliza, mipukutuyo imakulungidwa ndikuperekedwa kwa makasitomala, ndipo pali njira yokhwima pakati.

Mfundo zaukadaulo wopangira zinthu

TPU masterbatch: TPU masterbatch pambuyo pa kutentha kwambiri

makina oponyera;

Filimu ya TPU;

Kumatira makina omatira: TPU imayikidwa pa makina omatira omatira oti azitha kutentha/kuwala ndipo imakutidwa ndi guluu wa acrylic/guluu wothira kuwala;

Kupaka utoto: Kupaka utoto filimu yotulutsa PET ndi TPU yomatidwa;

Chophimba (chogwira ntchito): chophimba cha nano-hydrophobic pa TPU pambuyo pa lamination;

Kuumitsa: kuumitsa guluu pa filimu pogwiritsa ntchito njira yowumitsa yomwe imabwera ndi makina opaka utoto; njira imeneyi ipanga mpweya wochepa wa zinyalala zachilengedwe;

Kuduladula: Malinga ndi zofunikira pa dongosolo, filimu yophatikizana idzadulidwa m'makulidwe osiyanasiyana ndi makina odulira; njirayi ipanga m'mbali ndi ngodya;

Kuzungulira: filimu yosinthira mtundu ikadulidwa imakulungidwa mu zinthu;

Kupaka zinthu zomalizidwa: kuyika zinthuzo m'nyumba yosungiramo katundu.
