Mafilimu Otentha ndi Ozizira Opangidwa ndi Composite

Kodi Mafilimu Otentha ndi Ozizira Ophatikizana ndi Chiyani?

Makanema otentha ndi ozizira ophatikizika ndi mafilimu apulasitiki okhala ndi zigawo zambiri omwe amapangidwa kuti azigwira ntchito pansi pa njira zolumikizira kutentha ndi kupsinjika kwa mlengalenga.
Nthawi zambiri amapangidwa ndi zinthu monga PET, BOPP, PE, CPP, kapena Nylon zolumikizidwa pamodzi pogwiritsa ntchito zomatira kapena co-extrusion.
Makanema awa amagwiritsidwa ntchito kwambiri popaka, kusindikiza, kuyika, ndi kutenthetsa chifukwa cha kusinthasintha kwawo kutentha komanso kapangidwe kake.

Kodi kusiyana kwakukulu pakati pa mafilimu otentha opangidwa ndi zinthu zosiyanasiyana ndi mafilimu ozizira opangidwa ndi zinthu zosiyanasiyana ndi kotani?

Makanema otentha ophatikizika amafunikira kutentha ndi kupanikizika kuti agwirizane—omwe amagwiritsidwa ntchito kwambiri popaka mafuta kapena kutseka kutentha.
Makanema ozizira ophatikizika, kumbali ina, amatha kugwiritsidwa ntchito pogwiritsa ntchito zomatira zomwe zimakhudzidwa ndi kupanikizika popanda kutentha, zomwe zimapangitsa kuti zikhale zoyenera kupaka mafuta ozizira kapena njira zotsika kutentha.
Makanema ena ophatikizika amapangidwa kuti azithandizira kuyika mafuta otentha ndi ozizira, zomwe zimapereka njira zosiyanasiyana zogwiritsira ntchito.

Ndi zipangizo ziti zomwe zimagwiritsidwa ntchito kwambiri m'mafilimu otentha ndi ozizira ophatikizana?

Kapangidwe ka zinthu wamba ndi:
• PET/PE
• BOPP/CPP
• Nayiloni/PE
• BOPP/PE yokhala ndi zomatira zopangidwa ndi EVA kapena zosungunulira.
Kuphatikiza kumeneku kumapereka zinthu zabwino monga kuteteza zotchinga, kukana kutentha, kuwonekera bwino, komanso kutseka.

Kodi mafilimu otentha ndi ozizira omwe amagwiritsidwa ntchito nthawi zambiri ndi otani?

Makanema opangidwa ndi zinthu zosiyanasiyana amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo:
• Mapaketi osinthika a chakudya (matumba oziziritsa, zakudya zozizira, matumba a mkaka)
• Kupaka mapepala, makadi, kapena mapaketi osinthika
• Kutseka matumba a mankhwala ndi azachipatala
• Kuphimba ndi zotetezera kutentha kapena zoteteza
• Zolemba, zipangizo zotsatsa, ndi zosindikizira zosindikizidwa zomata.
Kusinthasintha kwawo pa kutentha kumawapangitsa kukhala abwino kwambiri pa ntchito zodzichitira zokha kapena zamanja.

Kodi mafilimu ophatikizana awa ndi oyenera kupakidwa chakudya chapamwamba?

Inde, mafilimu ambiri otentha ndi ozizira opangidwa ndi utomoni ndi zomatira zotetezeka ku chakudya.
Amakwaniritsa malamulo a FDA, EU, ndi GB okhudzana ndi chakudya ndipo amapereka mphamvu zabwino kwambiri zotchingira chinyezi, mpweya, ndi fungo.
Amagwiritsidwa ntchito kwambiri m'matumba otayira mpweya, matumba obweza, ndi zophimba zokhwasula-khwasula.

Kodi ubwino wogwiritsa ntchito mafilimu otentha ndi ozizira ophatikizana ndi chiyani?

• Mphamvu ya makina komanso kukana kubowoka
• Kusindikiza bwino kwambiri komanso kusalala kwa pamwamba
• Kugwirizana mwamphamvu ndi pepala, bolodi, kapena mafilimu ena
• Kukana mafuta, mafuta, ndi mankhwala
• Kugwirizana ndi njira zonse ziwiri zotsekera kutentha komanso zoziziritsa kuzizira
• Kugwira ntchito bwino kwa zotchinga zomwe zingasinthidwe pogwiritsa ntchito zitsulo kapena zigawo zokutira.

Kodi ndi makulidwe otani omwe alipo pa mafilimu otentha ndi ozizira ophatikizana?

Kukhuthala kumasiyana malinga ndi kapangidwe ka filimu ndi momwe imagwiritsidwira ntchito, nthawi zambiri kuyambira ma microns 20 mpaka ma microns 150.
Mafilimu owonda (monga ma microns 25–40) amagwiritsidwa ntchito popaka utoto kapena zigawo zamkati, pomwe mafilimu okhuthala (oposa ma microns 80) amapereka mphamvu yabwino komanso kutseka ma CD akunja.
Mafilimu okhala ndi zigawo zambiri amatha kuphatikiza ma gauges osiyanasiyana kuti akwaniritse bwino ntchito.

Kodi mafilimu awa angasindikizidwe kapena kusinthidwa kukhala zitsulo?

Inde, mafilimu ambiri opangidwa ndi zinthu zosiyanasiyana amasindikizidwa pogwiritsa ntchito njira zolembera, zolembera, kapena za digito.
Mitundu yopangidwa ndi zinthu zopangidwa ndi zitsulo (monga PET kapena BOPP yopangidwa ndi zitsulo) imapereka mawonekedwe abwino komanso zotsatira zabwino zowoneka bwino pamapaketi apamwamba.
Kuchiza ndi corona kapena mankhwala kumatsimikizira kuti inki imamatirira mwamphamvu komanso kuti utoto wake ukhale wowala.

Kodi mafilimu otentha ndi ozizira opangidwa ndi zinthu zosiyanasiyana amatha kubwezeretsedwanso?

Zimadalira kapangidwe ka zinthuzo.
Kapangidwe ka zinthu chimodzi monga PE/PE kapena PP/PP laminate ndi kosavuta kubwezeretsanso.
Mafilimu ophatikizika a zinthu zambiri (monga PET/PE kapena BOPP/Nylon) ndi ovuta kuwabwezeretsanso koma amatha kupangidwa kukhala ochezeka kwambiri pogwiritsa ntchito zomatira zopanda zosungunulira kapena zigawo zowola.
Opanga akupereka kwambiri mafilimu ophatikizika obwezeretsanso kapena amodzi kuti athetse mavuto okhazikika.

Kodi nthawi yosungiramo zinthu ndi yotani?

Mu malo oyenera osungiramo zinthu—ozizira, ouma, komanso osakhudzidwa ndi dzuwa—mafilimu opangidwa ndi zinthu zosakanikirana nthawi zambiri amakhala ndi moyo wa miyezi 12 mpaka 18.
Kusunga pamalo otetezedwa ndi kutentha (15–25°C) kumalimbikitsidwa kuti kupewe kupindika, kutayika kwa ma glue, kapena kuwonongeka kwa zosindikizira.
