EVA Packaging Film for Rubber Additives
ZopandaTMKanema wapackage wa EVA adapangidwa mwapadera kuti apange matumba ang'onoang'ono a zowonjezera mphira (monga 100g-5000g) okhala ndi makina odzaza chisindikizo (FFS). Zowonjezera mphira kapena mankhwala osiyanasiyana (monga peptizer, anti-aging agent, machiritso, machiritso accelerator, mafuta opangira labala) amagwiritsidwa ntchito kwambiri posakaniza mphira, ndipo ndi zinthu zochepa zokha zomwe zimafunikira pagulu lililonse. Chifukwa chake maphukusi ang'onoang'onowa atha kuthandiza ogwiritsa ntchito zinthu kuti awonjezere magwiridwe antchito ndikupewa kuwononga zinthu. Kanemayo amapangidwa ndi utomoni wa EVA (copolymer wa ethylene ndi vinyl acetate) womwe uli ndi malo otsika osungunuka komanso ogwirizana bwino ndi mphira kapena utomoni. Choncho matumba pamodzi ndi zipangizo zili akhoza mwachindunji kuika mu chosakanizira. Matumbawo adzasungunuka ndikubalalika mumagulu a mphira ngati chinthu chaching'ono chothandiza.
Makanema okhala ndi malo osungunuka osiyanasiyana (madigiri 65-110 Celsius) ndi makulidwe amapezeka mosiyanasiyana pogwiritsa ntchito mikhalidwe.
