(1) Mhedzisiro yezvigadzirwa
Mhando dzakasiyana dzePC uye ABS resin musanganiswa weiyo alloy ine musiyano mukuru mukuita.Zvinogona kuonekwa kubva kuMufananidzo 6-22 kuti yakakwira rubha yemukati inovandudza simba rekukanganisa kwePC/ABS system, asi inokuvadza zvakanyanya hunhu hwekubatana pakati pezvikamu, nekudaro kuderedza kusimba kweiyo alloy.Naizvozvo, kusarudza ABS ine yakakodzera rabha yemukati haingogone kuvandudza simba rekuita remusanganiswa, asi zvakare kuwedzera simba rayo rekukotama synergistically.Kana ABS ine yakaderera rabha yemukati yakashandiswa, iyo yekukotama simba reiyo alloy inowoneka synergistic kusimudzira.Uye zvakare, yakakwira acrylonitrile, yakaderera rabha yemukati uye yakakwira molecular uremu ABS inogona kuvandudza kupisa kwekupisa kwealloy.
(2) Pesvedzero yePC/ABS musanganiswa ratio pane zvivakwa zvealloy
Iko kuenderana uye michina yePC / ABS blend system yakanangana nezviri mukati mechikamu chimwe nechimwe muhurongwa.Cao Mingan et al.yakawana akasiyana maPC/ABS alloys ane hunhu hwakasiyana nekugadzirisa kusanganisa reshiyo yePC neABS resin.Izvo zvivakwa zvePC/ABS alloy zvine hukama hwemutsara nezvirimo zveABS, uye zvakapotsa teerera yekuwedzera.Izvo zvese zvimiro zvePC/ABS alloy zviri pakati pePC neABS, uye simba rekuita rine superadditivity mhedzisiro (kureva synergy athari) uye antagonism mhedzisiro ine chikamu.
(3) Mhedzisiro yechikamu chechitatu
Kupisa kwekudzivirira uye kugadzikana kwekupisa kwePC/ABS alloy kunogona kuvandudzwa nekuwedzera benzothiazole uye polyimide.Iyo fluidity yePC/ABS alloy inogona kuvandudzwa nekuwedzera kugadzirisa ma modifiers akadai se ethylene oxide/propylene oxide block copolymer, MMA/St copolymer uye olefin/acrylic vhiniga copolymer.Pamusoro pezvo, kuitira kuvandudza simba rakabatanidzwa rePC/ABS alloy jekiseni zvigadzirwa, PMMA, SAN, SBR, acrylic vhiniga elastomer, low density polyolefin, ethylene/acrylic vhiniga/acetic acid, ethylene (vhiniga) copolymer, PC/ ethylene block. kana graft copolymer nezvimwe zvinhu zvinowanzowedzerwa.
(4) Mhedzisiro yekugadzira tekinoroji
PC uye ABS yekusanganisa michina inogona kusarudza kubva papatya screw extruder uye imwechete screw extruder ine static musanganiswa.Jong Han Chun anotenda kuti mhedzisiro yekuramba ichikanya extruder yakanaka.Panyaya yekubatanidza maitiro, mhedzisiro yechipiri-yekurongeka yekubatanidza iri nani.Zvisinei, muchikamu chechipiri chekubatanidza, chikamu chezvigadzirwa zvinoda kubudiswa kaviri pakupisa kwepamusoro, iyo ine simba guru rekushandisa, nyore kuderedza zvinhu uye kuderedza zvinhu zvealloy.
Iyo nzira yekuumba zvakare ine simba guru pane morphology uye chimiro chePC / ABS alloy.Semuenzaniso, mufananidzo wakaumbwa nekutsikirira epurasitiki unogona kuchengetedza zvirinani iyo microstructure heterogeneous dispersion state inoumbwa nekusanganiswa kwealloy, nepo jekiseni richiumba, pamwero wakakwira wekugera, nyika yekupararira inoshanduka uye inosvika pakuora kweyunifomu yakawandisa.Naizvozvo, simba rekuita remasamples maviri ane musiyano mukuru, uye simba rekuita reiyo compression molding sampu yakakwira.PC mumvura (yemvura inodarika 0.03%) uye tembiricha yakakwira (tembiricha yakakwira kupfuura 150 ℃) pasi pekuora kuri nyore, saka mukusanganiswa kana kuumbwa kusati kwaoma, kunofanirwawo kudzivirira stearic acid lubricant yakasanganiswa, kuti irege kukanganisa kushanda kwezvigadzirwa.
