(1) Mmetụta nke akụrụngwa
Ụdị dị iche iche nke PC na ABS resin ngwakọta nke alloy nwere nnukwu ọdịiche na arụmọrụ. Enwere ike ịhụ site na onyonyo 6-22 na ọdịnaya rọba dị elu na-eme ka ike mmetụta nke sistemu PC/ABS dịkwuo mma, mana na-emebi àgwà mmekọrịta dị n'etiti akụkụ ahụ, si otú a na-ebelata ikike tensile nke alloy. Ya mere, ịhọrọ ABS na ọdịnaya rọba kwesịrị ekwesị nwere ike ọ bụghị naanị melite ike mmetụta nke ngwakọta, kamakwa kwalite ike na-ehulata na synergistically. Mgbe ejiri ABS nwere obere rọba, ike na-ehulata alloy ga-apụta nkwalite synergistic. Tụkwasị na nke ahụ, nnukwu acrylonitrile, obere roba ọdịnaya na nnukwu molekụla ABS nwere ike imeziwanye nkwụsị ọkụ nke alloy.
(2) Mmetụta nke ngwakọta PC / ABS na njirimara nke alloy
Ndakọrịta na akụrụngwa akụrụngwa nke sistemụ ngwakọta PC / ABS metụtara ọdịnaya nke akụkụ ọ bụla na sistemụ. Cao Mingan et al. nwetara alloys PC/ABS dị iche iche nwere njirimara dị iche iche site n'ịgbanwe nha ngwakọta nke PC na resin ABS. Ngwongwo nke PC/ABS alloy nwere njikọ kwụ ọtọ na ọdịnaya nke ABS, yana ihe dị ka irube isi na mgbakwunye. Njirimara zuru oke nke PC/ABS alloy dị n'etiti PC na ABS, na ike mmetụta nwere mmetụta superadditivity (ie synergy mmetụta) na antagonism mmetụta na oke.
(3) Mmetụta nke akụkụ nke atọ
Enwere ike imeziwanye nguzogide okpomọkụ na nkwụsi ike nke PC/ABS alloy site na ịgbakwunye benzothiazole na polyimide. Enwere ike imeziwanye mmiri nke PC/ABS alloy site n'ịgbakwunye nhazi nhazi dị ka ethylene oxide/propylene oxide block copolymer, MMA/St copolymer na olefin/acrylic vinegar copolymer. Na mgbakwunye, iji melite ike nkwonkwo nke PC / ABS alloy injection ngwaahịa, PMMA, SAN, SBR, acrylic vinegar elastomer, obere njupụta polyolefin, ethylene / acrylic mmanya / acetic acid, ethylene (mmanya) copolymer, PC / ethylene ngọngọ. ma ọ bụ graft copolymer na ihe ndị ọzọ na-agbakwunyere.
(4) Mmetụta nke teknụzụ nhazi
Ngwakọta PC na ABS nwere ike ịhọrọ site na ejima ịghasa extruder na otu ịghasa extruder nwere igwekota static. Jong Han Chun kwenyere na mmetụta nke ịhịa aka n'ahụ na-aga n'ihu dị mma. N'ihe gbasara ọnọdụ ngwakọta, mmetụta nke nchịkọta nke abụọ dị mma. Otú ọ dị, n'usoro nke abụọ na-agwakọta, akụkụ nke ihe dị mkpa ka a na-agbapụta ugboro abụọ na okpomọkụ dị elu, nke nwere ike oriri dị elu, dị mfe imebi ihe ma belata ihe onwunwe nke alloy.
Usoro ịkpụzi ahụ nwekwara mmetụta dị ukwuu na morphology na nhazi nke PC/ABS alloy. Dị ka ihe atụ, ihe nlere kpụrụ site na ịpị plastic nwere ike mma ịnọgide na-enwe microstructure heterogeneous dispersion steeti kpụrụ site alloy Ịgwakọta, mgbe injection ịkpụzi, na a elu shiee ọnụego, dispersion steeti mgbanwe na esịmde oke edo decomposition. Ya mere, mmetụta ike nke abụọ sample nwere nnukwu ọdịiche, na mmetụta ike nke mkpakọ ịkpụzi sample bụ elu. PC na mmiri (mmiri ọdịnaya karịrị 0.03%) na elu okpomọkụ (okpomọkụ dị elu karịa 150 ℃) n'okpuru mfe mweda, otú na ngwakọta ma ọ bụ ịkpụzi tupu ihicha, kwesịkwara izere stearic acid lubricants agwakọta, ka ọ ghara imetụta ndị arụmọrụ nke ngwaahịa.
