Chosintha cha ACR impact ndi acrylic copolymer yokhala ndi kapangidwe ka core-shell, komwe kamagwira ntchito zofunika kwambiri pakukonza pulasitiki monga PVC
1. Kulimbikitsa kukana mphamvu
Mwa kulowetsa mizere yasiliva ndi mikanda yoduladula kudzera mu elastomer yapakati, mphamvu ya impact imayamwa, zomwe zimapangitsa kuti mphamvu ya impact ya chinthucho ikhale yabwino kwambiri (makamaka m'malo otentha pang'ono); Kapangidwe ka kapangidwe ka chipolopolo chapakati kangathe kuwonjezera mphamvu ya impact ndi nthawi zoposa 6 ndikusunga kulimba kwa 90% pa -40 ℃.
2. Kukonza bwino magwiridwe antchito a processing
Limbikitsani kupangidwa kwa pulasitiki ya PVC, kufupikitsa nthawi yokonza, kukonza kuyenda bwino kwa madzi ndi kukhazikika; Kuchepetsa vuto la kusweka kwa madzi ndikuwongolera mtundu wa ma profiles ovuta a magawo osiyanasiyana.
3. Kukonza magwiridwe antchito mokwanira
Konzani kusalala kwa pamwamba pa chinthucho ndikuchotsa zolakwika monga maso a nsomba ndi zizindikiro za kuyenda kwa madzi; Kuonjezera kukana nyengo, kukana kutentha, komanso kukhazikika kwa mankhwala, makamaka oyenera zinthu zakunja.
4. Ubwino wapadera wogwiritsira ntchito
Kugwirizana bwino ndi PVC, komwe kumafalikira mofanana kuti kupewe kusonkhana; Poyerekeza ndi zosintha monga CPE, ACR ili ndi kutentha kwakukulu kokonza komanso magwiridwe antchito apamwamba osinthira; Transparent ACR imatha kusunga kuwala kopitilira 85% ndipo ndiyoyenera zinthu zowonekera; Kuchuluka kwa nthawi zambiri kowonjezera ndi 0.5-5phr, ndipo kusakaniza mwachindunji ndi zodzaza za alkaline kuyenera kupewedwa. Pakadali pano, Bangtai Petrochemical ACR yakhala imodzi mwa zosintha zomwe zimakondedwa kwambiri pa ma profiles olimba a PVC, mapaipi, ndi ma alloys apulasitiki auinjiniya.
5. Sankhani chitsanzo choyenera cha ACR
Mbiri/Chitoliro: Mitundu yolemera kwambiri ya mamolekyulu ndi yomwe imakondedwa, yokhala ndi kulemera kwa mamolekyulu kopitilira 500000, komwe kumatha kuwonjezera mphamvu yosungunuka ndi kupitirira 40% ndikuletsa bwino kusweka kwa kusungunuka kwa extrusion; Zigawo zopangidwa ndi jakisoni/zinthu zopyapyala: Mitundu yolemera yochepa ya mamolekyulu imalimbikitsidwa, yokhala ndi kulemera kwa mamolekyulu kwa 300000 mpaka 500000 kuti muchepetse kukhuthala kwa kusungunuka ndikuwonjezera liwiro lodzaza ndi 25% -30%; Zinthu zowonekera bwino ziyenera kuphatikizidwa ndi MBS (gawo losungunuka 9.4-9.5) kuti mugwiritse ntchito pa compound, yokhala ndi transmittance yopepuka ya>85%
