Matumba a Rubber Compounding
Kuphatikizika kwa mphira kumatanthauza kuwonjezera mankhwala ena ku mphira waiwisi kuti apeze zomwe akufuna. ZopandaTM thumba lopangira mphiras ndi matumba opangidwa mwapadera kuti azinyamulira zopangira mphira ndi mankhwala omwe amagwiritsidwa ntchito popanga mphira. Zida monga kaboni wakuda, anti-aging agent, accelerator, machiritso ndi mafuta onunkhira a hydrocarbon akhoza kuyesedwa kale ndikusungidwa kwakanthawi m'matumba a EVA. Popeza kuti zinthu zamatumba zimagwirizana bwino ndi mphira wachilengedwe komanso wopangidwa, matumbawa pamodzi ndi zinthu zodzaza akhoza kuikidwa mwachindunji mu chosakanizira, ndipo matumbawo adzasungunuka ndikubalalika kwathunthu mu mphira ngati chogwiritsira ntchito chochepa.
Matumbawa amathandizira kwambiri ntchito yophatikizira mphira popereka makonzedwe enieni a mankhwala, malo ogwirira ntchito oyeretsa komanso kuchita bwino kwambiri.
Matumba okhala ndi malo osungunuka osiyanasiyana (kuyambira 65 mpaka 110 digiri Celsius) amapezeka pamikhalidwe yosakanikirana ya mphira. Kukula ndi mtundu zitha kusinthidwa malinga ndi zomwe kasitomala akufuna.
