Kusiyana Pakati pa BOPP, OPP ndi PP Matumba.

Makampani azakudya amagwiritsa ntchito kwambiri ma pulasitiki a BOPP.Matumba a BOPP ndi osavuta kusindikiza, kuvala ndi laminate zomwe zimawapangitsa kukhala oyenera kunyamula zinthu monga zatsopano, zokometsera ndi zokhwasula-khwasula.Pamodzi ndi matumba a BOPP, OPP, ndi PP amagwiritsidwanso ntchito pakuyika.Polypropylene ndi polima wamba pakati pa atatu omwe amagwiritsidwa ntchito popanga matumba.

OPP imayimira Oriented Polypropylene, BOPP imayimira Biaxially Oriented Polypropylene ndipo PP imayimira Polypropylene.Onse atatu amasiyana pamapangidwe awo.Polypropylene yomwe imadziwikanso kuti polypropene ndi polima ya thermoplastic semicrystalline polima.Ndi yolimba, yamphamvu komanso imatsutsa kwambiri.Zikwama zoimilira, zikwama za spout ndi zikwama za ziplock zimapangidwa kuchokera ku polypropylene.

Ndizovuta kwambiri kusiyanitsa pakati pa OPP, BOPP ndi PP mapulasitiki poyamba.Kusiyanaku kumatha kumveka pogwirana chifukwa PP ndi yofewa pomwe OPP ndi yofewa.Ndikofunika kumvetsetsa kugwiritsa ntchito matumba a OPP, PP ndi BOPP muzinthu zenizeni zapadziko lapansi kuti muwasiyanitse.ThePPkapena matumba a polypropene amagwiritsidwa ntchito ngati matumba osaluka.Amathandizidwa kuti apange chinyezi kapena kuyamwa madzi.

Matewera, zopukutira zaukhondo ndi zosefera mpweya pakati pa ena ndi zinthu wamba PP.Zofananazo zimagwiritsidwanso ntchito popanga zovala zotentha chifukwa zimapereka zotchinga kutentha.Matumba a OPP ndi owoneka bwino komanso amakhala ndi mphamvu zolimba kwambiri.Amalimbana ndi kutentha kwambiri koma amakwinya ngati atagwiritsidwa ntchito movutikira.Matepi omatira owonekera amapangidwa pogwiritsa ntchito njira yomweyo.

Ndizovuta kung'amba ndipo matumba a OPP amagwiritsidwa ntchito polongedza zikopa ndi zovala pakati pa ena.Matumba a BOPP ndi matumba owoneka bwino a polyethylene.Maonekedwe a biaxial amawapangitsa kuti aziwoneka bwino ndipo amawapangitsa kukhala oyenera kuyika chizindikiro posindikiza pamwamba.Matumba a BOPP amagwiritsidwa ntchito popanga malonda ogulitsa.The biaxial orientation amawonjezera mphamvu ndipo amatha kunyamula katundu wolemera.

Matumbawa salowa madzi.

Zomwe zili mkati mwawo zimatetezedwa ku chinyezi kwa nthawi yayitali.Ndiwo chisankho choyamba mumakampani opangira nsalu.Matumba a PP, OPP ndi BOPP sagonjetsedwa ndi asidi, alkali ndi zosungunulira za organic.Ichi ndichifukwa chake amagwiritsidwa ntchito m'mafakitale onyamula katundu komwe kusungirako ndi zoyendera pansi pakusintha kwamlengalenga sikungapewedwe.Amapanga zinthuzo kuchokera ku chinyezi ndi fumbi ngati mafilimu a chakudya.

Atha kusinthidwanso ndipo kupanga kwawo kumaphatikizapo kutulutsa mpweya wochepa.Matumba a PP, BOPP ndi OPP nawonso ndi abwino kuchokera ku chilengedwe.Rishi FIBC ndiwopanga zikwama za BOPP ndipo amazipereka pamitengo yotsika mtengo yamsika.
