(1) Umthelela wezinto ezingavuthiwe
Izinhlobo ezahlukene ze-PC kanye ne-ABS resin blend ye-alloy inomehluko omkhulu ekusebenzeni.Kungabonakala kuMfanekiso 6-22 ukuthi okuqukethwe kwerabha ephezulu kuthuthukisa amandla omthelela wesistimu ye-PC/ABS, kodwa kulimaza kakhulu ukuziphatha kwe-mutual capacitance phakathi kwezigaba, ngaleyo ndlela kunciphisa izakhiwo eziqinile ze-alloy.Ngakho-ke, ukukhetha i-ABS enokuqukethwe kwerabha efanele akukwazi nje ukuthuthukisa amandla omthelela wenhlanganisela, kodwa futhi kuthuthukise amandla ayo okugoba ngokuvumelana.Lapho kusetshenziswa i-ABS enokuqukethwe kwerabha ephansi, amandla okugoba engxubevange azovela njengesithuthukisi se-synergistic.Ngaphezu kwalokho, i-acrylonitrile ephezulu, okuqukethwe kwerabha ephansi kanye nesisindo esiphezulu se-molecular ABS kungathuthukisa ukumelana nokushisa kwe-alloy.
(2) Umthelela wesilinganiso senhlanganisela ye-PC/ABS ezakhiweni zengxubevange
Ukuhambisana kanye nezakhiwo zemishini ze-PC/ABS blend system zihlobene ngokuqondile nokuqukethwe kwengxenye ngayinye ohlelweni.UCao Mingan et al.ithole ama-alloys e-PC/ABS ahlukahlukene anezici ezihlukile ngokulungisa isilinganiso sokuhlanganisa se-PC ne-ABS resin.Izici ze-PC/ABS alloy zinobudlelwano bomugqa nokuqukethwe kwe-ABS, futhi cishe zithobela okungeziwe.Izakhiwo eziphelele zengxubevange ye-PC/ABS ziphakathi kwe-PC ne-ABS, futhi amandla omthelela anomphumela we-superadditivity (okungukuthi umthelela we-synergy) kanye nomphumela wokuphikisa ngengxenye.
(3) Umphumela wengxenye yesithathu
Ukumelana nokushisa nokuzinza kokushisa kwe-PC/ABS alloy kungathuthukiswa ngokungeza i-benzothiazole ne-polyimide.I-fluidity ye-PC/ABS alloy ingathuthukiswa ngokwengeza izilungisi zokucubungula ezifana ne-ethylene oxide/propylene oxide block copolymer, i-MMA/St copolymer ne-olefin/acrylic copolymer uviniga.Ngaphezu kwalokho, ukuze kuthuthukiswe amandla ahlangene emikhiqizo yomjovo we-PC/ABS ingxubevange, i-PMMA, SAN, SBR, acrylic vinegar elastomer, low density polyolefin, ethylene/acrylic vinegar/acetic acid, ethylene (vinegar) copolymer, PC/ethylene block noma i-graft copolymer nezinye izinto ngokuvamile ziyengezwa.
(4) Umthelela wokucubungula ubuchwepheshe
Imishini yokuhlanganisa ye-PC kanye ne-ABS ingakhetha ku-twin screw extruder kanye ne-screw extruder eyodwa ene-mixer emile.U-Jong Han Chun ukholelwa ukuthi umthelela we-extruder eqhubekayo yokuxova ulungile.Mayelana nemodi yokuxuba, umphumela wokuhlanganiswa kwe-oda lesibili ungcono.Kodwa-ke, ekuxubeni kwe-oda lesibili, ingxenye yezinto zokwakha idinga ukukhishwa kabili ekushiseni okuphezulu, okunokusetshenziswa kwamandla aphezulu, kulula ukululaza izinto kanye nokunciphisa izakhiwo ze-alloy.
Indlela yokubumba nayo inethonya elikhulu ku-morphology kanye nesakhiwo se-PC/ABS alloy.Isibonelo, isifanekiso esakhiwe ngokucindezela ipulasitiki singagcina kangcono isimo se-microstructure heterogeneous dispersion esakhiwe ukuxuba ingxubevange, kuyilapho ukubumba komjovo, ngenani eliphezulu lokugunda, isimo sokuhlakazeka siyashintsha futhi sifinyelele ukubola okufanayo okufana nokweqile.Ngakho-ke, amandla omthelela wamasampuli amabili anomehluko omkhulu, futhi amandla omthelela wesampula yokubumba yokucindezelwa aphezulu.I-PC emanzini (okuqukethwe kwamanzi kungaphezu kuka-0.03%) kanye nezinga lokushisa eliphezulu (izinga lokushisa lingaphezu kuka-150 ℃) ngaphansi kokuwohloka kalula, ngakho-ke ekuhlanganiseni noma ekubunjweni ngaphambi kokumiswa, kufanele futhi kugweme izithambisi ze-stearic acid ezixutshwe, ukuze zingathinti ukusebenza kwemikhiqizo.
