pvc resin kwa filimu yolimba
pvc utomoni wa filimu yolimba,
PVC utomoni filimu kalasi, PVC utomoni kwa filimu, PVC utomoni kwa filimu mandala,
Mafilimu Olimba a PVC ndi zinthu zosunthika zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana zolongedza.Chogulitsacho ndi chosavuta kugwiritsa ntchito potsutsana ndi magawo ena apulasitiki…
Pakuti kupanga ndi ntchito PVC okhwima mandala filimu, utomoni amakhala ndi yopapatiza kugawa utomoni polymerization digiri kuonetsetsa ntchito yake yabwino plasticizing ndi katundu mawotchi. .
Polyvinyl chloride (PVC) utomoni ndi mkulu polima opangidwa ndi polymerization wa ethylene.Kuyimitsidwa polymerization ntchito monga wamba mafakitale polymerization njira.Nthawi zambiri imakhala yolimba yomwe imatha kufewetsedwa ndi kutentha.Akatenthedwa, nthawi zambiri amakhala ndi kutentha kwa kutentha kapena kufewetsa, ndipo akhoza kukhala mu pulasitiki yotulutsa mpweya pansi pa mphamvu zakunja.Fakitale imatha kuwonjezera pulasitiki kapena othandizira ena kuti akwaniritse zofunikira zopanga malinga ndi zofunikira zamapulasitiki.
Kalasi S-1300 makamaka ntchito kupanga mkulu-mphamvu kusinthasintha mankhwala, mbamuikha zipangizo, okhwima ndi kusintha extrusion akamaumba ndi insulating zipangizo, etc. monga filimu woonda, mbale woonda, chikopa yokumba, waya, chingwe m'chimake ndi zofewa mitundu yonse ya mbiri.
