Mafilimu Omatira a TPU Hot-Melt | Kupaka Nsalu ndi Thovu
Mafilimu Omatira a TPU Hot-Melt Adhesive (HMA)
Pa ntchito zomangira ndi zomangira, kupambana kumadalira pa kukhazikika kwa zinthu izi:
kumamatira ku zinthu zenizeni, zenera loyatsira kutentha,
ndikulimba pambuyo pa ukalamba(kutentha, chinyezi, kusinthasintha, kusamba, kukhudzana ndi mankhwala).
Mafomu operekera:
Mafilimu a TPU HMA (ma pellets)zotulutsira/kuphimba filimu
Makanema omatira a TPU osungunuka ndi kutentha(kutengera pulojekiti, ngati papemphedwa).

Mapulogalamu Odziwika
- Kupaka nsalu ndi zovala: nsalu kuchokera ku nsalu kupita ku nembanemba, chizindikiro/chigamba chomangira.
- Nsapato: pamwamba mpaka pa mzere, zigawo zolimbitsa, TPU-to-EVA/thovu lomangirira (lodalira njira).
- Chikopa / chikopa chopangidwa: zigawo zokongoletsera ndi zomangira zomangira.
- Zosakaniza za mafakitale: milu ya filimu-laminate komwe kutentha ndi kusungidwa kwa ukalamba ndizofunikira.
Kusankha Mwachangu (Sankhani Choletsa Chachikulu)
Kutsegula kwa Kutentha Kochepa
Ngati zinthu zogwiritsidwa ntchito pansi pa nthaka sizikhudzidwa ndi kutentha kapena kutentha kwa mzere kumakhala kochepa.
- Chofunikira pa kutentha kotsika
- Zenera lalikulu la lamination
- Chepetsani chiopsezo cha kuchepa/kupotoza
Mphamvu Yaikulu Yogwirizana
Pamene kupeta/kudula ndi mphamvu yaikulu (kugwirizana kwa kapangidwe kake).
- Mphamvu yogwirizana kwambiri
- Kukana bwino kukameta ubweya
- Dongosolo lomatira lokhazikika pa substrate
Kulimba kwa Ukalamba / Kusamba
Pamene zomangira ziyenera kupirira kutentha - chinyezi, kusamba, kusinthasintha, ndi nthawi.
- Kusunga zikopa pambuyo pa ukalamba
- Njira yopewera chinyezi/kutentha
- Kuchepetsa chiopsezo cha delamination
Ngati polojekiti yanu ili ndiziwiri kapena kuposerapozoletsa zolimba (monga kuyatsa kutentha kochepa + kupukuta kwambiri + kulimba kwa kusamba),
ndiZogwira Ntchito Zapamwambamlandu: zenera la njira yopangira + njira liyenera kulumikizidwa pamodzi.

Njira Zofala Zolephera (Chifukwa → Kukonza)
Mu mgwirizano wa filimu yotentha kwambiri, "umamatira poyamba" n'kosavuta. Nkhondo yeniyeni ndi mgwirizano wokhazikika pakati pa
zenera la kutentha, kupanikizika/nthawindikukhudzana ndi ukalamba.
| Chizindikiro | Chifukwa Chofala Kwambiri | Konzani Malangizo |
|---|---|---|
| Amachotsa khungu poyamba, kenako amasungunuka pambuyo pa ukalamba | Dongosolo lomatira silikugwirizana ndi gawo lapansi; mphamvu yogwirizana ndi yochepa kwambiri; njira yokalamba ikusowa | Sinthani njira yolumikizirana; onjezerani mphamvu yogwirizana; tsimikizirani ndi kutentha-chinyezi / kusamba nthawi zonse |
| Zenera lochepa loyatsira (mzere wosakhazikika) | Zenera loyenda/kukhuthala latsekedwa kwambiri; kutentha kwa kuyatsa kwayandikira kwambiri malire a ntchito | Kukulitsa zenera loyatsira; sinthani kayendedwe ka kusungunuka; sinthani makulidwe a filimu & momwe lamination imagwirira ntchito |
| Chigwirizano chofooka pa gawo limodzi lokha | Kusagwirizana kwa mphamvu pamwamba; zinthu zodetsa/zotulutsa; njira yolakwika yoyambira | Njira yodziwira malo otsetsereka; chithandizo cha pamwamba/kuyang'ana koyamba; fufuzani mwachangu malo otsetsereka |
| Kukweza m'mphepete / ngalande / makwinya pambuyo pa lamination | Kusagwirizana, kuzizira, kuyatsa kosagwirizana, kapena mavuto ogawa mphamvu | Kusintha kwa njira (kutentha/kupanikizika/nthawi/kuzizira); sinthani kapangidwe kake; khazikitsani mikhalidwe yozungulira |
| Filimu imatuluka kwambiri (kutuluka magazi / kusokoneza zosindikiza) | Mphamvu yochepa yosungunuka ikayamba kugwira ntchito; kutentha kwambiri; makulidwe okwera kwambiri kuti kapangidwe kake kasawonongeke | Wonjezerani mphamvu yosungunuka; chepetsani kutentha koyambitsa; konzani makulidwe ndi kuthamanga/nthawi yothira lamination |
| Kuphwanyika / kusweka mu nthawi yozizira kapena nthawi ikatha | Kupanga kwake kuli kolimba kwambiri; phukusi lotentha pang'ono silikupezeka; njira yokalamba sikugwirizana | Sinthani kusinthasintha kwa kutentha kochepa; sinthani bwino gawo lolimba/lofewa; tsimikizirani kayendedwe ka kusinthasintha |
Zimene Tiyenera Kupangira Mndandanda Waufupi
Chikwama cholumikizira
- Gawo A / Gawo B (zinthu, zokutira, mankhwala pamwamba)
- Cholinga cha makulidwe a filimu (ndi kulekerera)
- Mtundu wa chigwirizano (kuchotsa peel vs kumeta)
Njira ndi kutsimikizira
- Kutentha kwa lamination, kuthamanga, nthawi yokhala
- Kuzizira ndi kupsinjika/kuzungulira
- Ndondomeko ya ukalamba: kutentha ndi chinyezi, nthawi yotsuka, mankhwala, kusinthasintha
Pemphani Zitsanzo / TDS
Tikhoza kuthandizira zonse ziwirima pellets(pa extrusion/coating yanu ya filimu) ndimafilimu omalizidwa(kutengera pulojekiti).
Gawani mfundo zazikulu zomwe zili pansipa ndipo tidzakulangizani mndandanda waufupi ndikupereka TDS/SDS kuti muyesedwe.
Kuti mupeze malangizo mwachangu, tumizani:
- Ma substrate:momwe zinthu zilili pamwamba (zothandizira kuchiritsidwa / zophimbidwa / zotulutsa)
- Chofunikira pa bond:peel/meat target ndi kutentha kwa ntchito
- Zenera loyambitsa:kutentha komwe kulipo kwa lamination ndi nthawi yokhala
- Ndondomeko ya ukalamba:kutentha-chinyezi, njira zotsukira, mankhwala, kusinthasintha (ngati kulipo)
- Fomu yoperekera:ma pellets opangira filimu, kapena filimu yomatira yomalizidwa (kukhuthala/kupingasa/kuzungulira)
