filimu TPU, monga chida cha polima chochita bwino kwambiri, chimakhala ndi gawo lofunikira m'magawo ambiri chifukwa cha mawonekedwe ake apadera akuthupi ndi mankhwala. Nkhaniyi idzatero
fufuzani muzolemba, njira zopangira, mawonekedwe, ndi kagwiritsidwe ntchito kafilimu TPU, kukutengani paulendo kuti muyamikire kukongola kwaukadaulo kwa nkhaniyi.
1. Zida zopangira filimu ya TPU:
Kanema wa TPU, yemwe amadziwikanso kuti thermoplastic polyurethane film, ndi filimu yopyapyala yopangidwa ndi polyurethane monga gawo lapansi kudzera munjira zinazake zopangira. Polyurethane ndi a
ma polima opangidwa ndi momwe ma polyols ndi isocyanates amachitira, omwe ali ndi kukana kwamphamvu kwambiri, kulimba, komanso kukana mankhwala. Kuti muwonjezere magwiridwe antchito ake,
zowonjezera zogwira ntchito monga ma antioxidants ndi zotsekemera za UV zimawonjezeredwanso panthawi yopanga mafilimu a TPU.
2. Njira yopangira:
Njira yopangafilimu TPUndi zabwino komanso zovuta, makamaka kuphatikiza njira zotsatirazi:
Aggregation reaction: Choyamba, pansi pa zochita za chothandizira, ma polyols ndi isocyanates amakumana ndi polymerization reaction kuti apange polyurethane prepolymers.
Sungunulani extrusion: Kutenthetsa prepolymer kukhala wosungunuka ndiyeno extrude mu filimu kupyolera mutu extruder.
Kuziziritsa ndi kupanga: Kanema wosungunula wotuluka amaziziritsidwa mwachangu ndi chogudubuza chozizirira kuti alimbike ndi kupanga.
Kukonza positi: kuphatikiza kudula, kupindika ndi masitepe ena, kuti pamapeto pake mupeze filimu yomalizidwa ya TPU.
3. Makhalidwe:
Makhalidwe a filimu ya TPU ndiye maziko ogwiritsira ntchito kwambiri, makamaka akuwonetsedwa m'mbali izi:
Mphamvu yayikulu komanso kukhazikika: Kanema wa TPU ali ndi mphamvu zolimba kwambiri komanso luso lotha kuchira, ndipo amatha kupirira mphamvu zazikulu zakunja popanda kupunduka.
Kukana kuvala: Kulimba kwapamtunda kumakhala kocheperako, kokhala ndi kukana kwabwino, koyenera kumadera osiyanasiyana ovuta.
Kutentha kukana: amatha kusunga bata mkati mwa kutentha kwa -40 ℃ mpaka 120 ℃.
Chemical resistance: Imalimbana bwino ndi mankhwala ambiri ndipo sichita dzimbiri mosavuta.
Kuthekera kwa chinyontho: Lili ndi mlingo wakutiwakuti wa chinyezi ndipo lingagwiritsidwe ntchito pamene kupuma kumafunika.
4. Kugwiritsa ntchito
Chifukwa chakuchita bwino kwambiri, filimu ya TPU yakhala ikugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikiza koma osachepera:
Makampani opanga zovala: Monga nsalu yopangira zovala, imakhala yopepuka, yopanda madzi, komanso yoteteza mpweya.
Malo azachipatala: Zida zakunja monga mikanjo ya opaleshoni, zovala zoteteza, ndi zina zotere zimagwiritsidwa ntchito popanga zida zachipatala.
Zida zamasewera: zomwe zimagwiritsidwa ntchito popanga nsapato zamasewera, zikwama, ndi zida zina zamasewera, zomwe zimapereka kulimba komanso kutonthoza.
Makampani opanga magalimoto: Monga chokongoletsera chamkati, amatha kukonza chitonthozo ndi kukongola kwa chilengedwe chagalimoto.
Munda womanga: womwe umagwiritsidwa ntchito popangira zida zapadenga, zosanjikiza madzi, ndi zina zambiri, kupititsa patsogolo kukana kwanyengo komanso mphamvu zamanyumba.
Mwachidule, monga zinthu zambiri zimagwira ntchito, filimu ya TPU yakhala ikugwiritsidwa ntchito kwambiri masiku ano. Zomwe zimapangidwira ndizopadera, njira zopangira
ndikupita patsogolo, ndipo mawonekedwe azinthu ndi osiyanasiyana. Kanema wa TPU, wokhala ndi zabwino zake zapadera, wawonetsa phindu losasinthika m'moyo watsiku ndi tsiku komanso magawo apamwamba kwambiri.
