Fyuluta yamakandulo ya mzere wa kanema wa BOPP

Popanga filimu ya BOPP, kusungunuka kwa polypropylene yapamwamba kwambiri kumapangidwa koyamba kukhala pepala kapena filimu wandiweyani kudzera pamutu wautali komanso wopapatiza wamakina, ndiyeno mumakina apadera otambasulira, pa kutentha kwina ndi liwiro lokhazikika, nthawi imodzi kapena masitepe. ndi sitepe Kanemayo amatambasulidwa mbali ziwiri ofukula (longitudinal ndi yopingasa), ndipo pambuyo kuzirala koyenera kapena kutentha kutentha kapena processing wapadera (monga corona, ❖ kuyanika, etc.).

Makanema omwe amagwiritsidwa ntchito nthawi zambiri a BOPP ndi awa: filimu wamba ya biaxially oriented polypropylene, filimu ya polypropylene yotchinga kutentha, filimu yonyamula ndudu, filimu ya biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matting film, etc.

Kanema wa BOPP ndichinthu chofunikira kwambiri chosinthika. Kanema wa BOPP ndi wopanda mtundu, wopanda fungo, wopanda fungo, wopanda poizoni, ndipo ali ndi mphamvu zolimba kwambiri, kulimba, kulimba, kulimba komanso kuwonekera bwino.

Mphamvu zapamtunda za filimu ya BOPP ndizochepa, ndipo chithandizo cha corona chimafunika musanamata kapena kusindikiza. Pambuyo pa chithandizo cha corona, filimu ya BOPP imatha kusindikiza bwino ndipo imatha kusindikizidwa kuti iwoneke bwino, chifukwa chake imagwiritsidwa ntchito ngati gawo lapamwamba la filimu yophatikizika.

The fyuluta chophimba ndi mbali yofunika kwambiri ya extruder, ndi mankhwala oyenerera okha akhoza kupangidwa kudzera fyuluta chophimba. Chophimba chojambulira cha extruder chimagwiritsidwa ntchito kusefera ndi kusakaniza zinthu zosiyanasiyana za viscous ndi zinthu monga mapulasitiki, ulusi wamankhwala, mphira, zomatira zotentha zosungunuka, zomatira, zokutira, ndi zosakaniza. Chophimba chojambula cha extruder chili ndi mtundu wa mauna. Ndi mauna lamba mtundu, ndi extruder akhoza m'malo fyuluta chophimba popanda kusokoneza kupanga kudzera basi chophimba chosinthira, kupulumutsa ntchito ndi nthawi, mankhwala ntchito ndi khola, kuzindikira basi kusintha chophimba ndi ntchito kwaulere, kuwonjezera ogwira kusefera nthawi, ndi kuchepetsa mtengo kupanga. .
