● Kukonza Kwachiwiri
Monga zinthu zogwiritsidwa ntchito mu thermoplastic, zinthu za Si-TPV zitha kukonzedwanso kuti zigwiritsidwe ntchito pazinthu wamba.
● Kupanikizika kwa Kupaka JekeseniKupanikizika kwa chogwirira kumadalira kwambiri mawonekedwe, makulidwe ndi malo a chipata cha chinthucho. Kupanikizika kwa chogwirira kuyenera kuyikidwa pamtengo wotsika poyamba, kenako pang'onopang'ono kukwera mpaka palibe zolakwika zina zomwe zimawoneka mu chinthu chopangidwa ndi jakisoni. Chifukwa cha mphamvu zotanuka za chinthucho, kupanikizika kwambiri kwa chogwirira kungayambitse kusintha kwakukulu kwa gawo la chipata cha chinthucho.
● Kupanikizika kwa msanaNdikofunikira kuti mphamvu yakumbuyo ikabwerera m'mbuyo ikhale 0.7-1.4Mpa, zomwe sizingotsimikizira kuti kusungunuka kwa kusungunuka kumagwirizana, komanso zimatsimikizira kuti zinthuzo sizikuwonongeka kwambiri ndi kudulidwa. Liwiro la screw lomwe limalimbikitsidwa la Si-TPV ndi 100-150rpm kuti zitsimikizire kusungunuka kwathunthu ndi pulasitiki ya zinthuzo popanda kuwonongeka kwa zinthu chifukwa cha kutentha kwa shear.
Ndemanga:
1. Zinthu zopangidwa ndi elastomer za Si-TPV zitha kupangidwa pogwiritsa ntchito njira zodziwika bwino zopangira thermoplastic, kuphatikizapo overmolding kapena co-molding ndi ma substrates apulasitiki monga PP,PA.
2. Kumveka kosalala kwambiri kwa Si-TPV elastomer sikufuna njira zina zowonjezera zokonzera kapena zokutira.
3. Mikhalidwe ya ndondomekoyi ingasiyane malinga ndi zida ndi njira zake.
4. Kuwumitsa kochotsa chinyezi m'malo ouma kumalimbikitsidwa nthawi zonse.
