Nā mea e pili ana i nā waiwai o PCABS alloy

(1) Ka hopena o nā mea maka

He ʻokoʻa nui ka hana o nā ʻano like ʻole o ka PC a me ka ABS resin blend o ka alloy. Hiki ke ʻike ʻia mai ka Figure 6-22 e hoʻomaikaʻi ana ka ʻikepili kiʻekiʻe i ka ikaika hopena o ka ʻōnaehana PC/ABS, akā hoʻopōʻino nui i ka ʻano capacitance like ma waena o nā pae, no laila e hōʻemi ana i nā waiwai tensile o ka alloy. No laila, ʻaʻole hiki ke hoʻomaikaʻi wale i ka ikaika o ka hopena o ka hui ʻana ke koho ʻana i ka ABS me ka ʻiʻo pāpaʻi kūpono, akā hoʻonui pū i kona ikaika kulou i ka synergistically. Ke hoʻohana ʻia ʻo ABS me ka haʻahaʻa haʻahaʻa haʻahaʻa, e ʻike ʻia ka ikaika wili o ka alloy e hoʻonui synergistic. Eia kekahi, hiki i ka acrylonitrile kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa a me ke kaumaha molecular kiʻekiʻe ABS hiki ke hoʻomaikaʻi i ka pale wela o ka alloy.

(2) ʻO ka mana o ka PC/ABS blend ratio ma luna o nā waiwai o ka alloy

ʻO ka hoʻohālikelike a me nā waiwai mechanical o ka ʻōnaehana hui PC/ABS pili pono i ka ʻike o kēlā me kēia ʻāpana i ka ʻōnaehana. ʻO Cao Mungan et al. loaʻa nā ʻāpana like ʻole PC / ABS me nā ʻano ʻokoʻa ma o ka hoʻoponopono ʻana i ka ratio hui ʻana o ka PC a me ka resin ABS. ʻO nā waiwai o ka PC/ABS alloy he pilina laina me ka ʻike o ABS, a pili i ka hoʻohui. ʻO nā waiwai holoʻokoʻa o ka PC / ABS alloy ma waena o PC a me ABS, a ʻo ka ikaika o ka hopena ka hopena superadditivity (ʻo ia hoʻi ka hopena synergy) a me ka hopena antagonism me ka hapa.

(3) Ka hopena o ke kolu o ka mea

Hiki ke hoʻomaikaʻi ʻia ka pale wela a me ke kūpaʻa wela o ka PC/ABS alloy ma ka hoʻohui ʻana i ka benzothiazole a me ka polyimide. Hiki ke hoʻomaikaʻi ʻia ka wai o PC/ABS alloy ma ka hoʻohui ʻana i nā mea hoʻololi e like me ka ethylene oxide/propylene oxide block copolymer, MMA/St copolymer a me ka olefin/acrylic vinegar copolymer. Eia kekahi, i mea e hoʻomaikaʻi ai i ka ikaika hui o ka PC / ABS alloy injection products, PMMA, SAN, SBR, acrylic vinegar elastomer, low density polyolefin, ethylene/acrylic vinegar/acetic acid, ethylene (vinegar) copolymer, PC/ ethylene block a i ʻole graft copolymer a me nā mea ʻē aʻe e hoʻohui pinepine ʻia.

(4) Ka hopena o ka ʻenehana hana

Hiki i nā mea hoʻohui hui PC a me ABS ke koho mai kahi extruder māhoe māhoe a me kahi extruder wili hoʻokahi me kahi hui static. Manaʻo ʻo Jong Han Chun he maikaʻi ka hopena o ka extruder kneading mau. Ma keʻano o ka hoʻohuiʻana i keʻano,ʻoi aku ka maikaʻi o ka hopena o ka hui lua. Eia nō naʻe, i ka lua o ka hui ʻana, pono e hoʻokuʻu ʻia kahi hapa o nā mea i ʻelua mau manawa i ke kiʻekiʻe kiʻekiʻe, he kiʻekiʻe ka hoʻohana ʻana i ka ikehu, maʻalahi e hoʻohaʻahaʻa i nā mea a hoʻemi i nā waiwai o ka alloy.

ʻO ke ʻano hana hoʻoheheʻe ʻia he mana nui i ka morphology a me ke ʻano o ka PC/ABS alloy. No ka laʻana, hiki i ka specimen i hoʻokumu ʻia ma ke kaomi ʻana i ka plastic ke mālama maikaʻi i ka microstructure heterogeneous dispersion state i hoʻokumu ʻia e ka hui ʻana o ka alloy, ʻoiai ka hoʻoheheʻe ʻia ʻana, ma kahi kiʻekiʻe o ka shear rate, hoʻololi ka mokuʻāina a hiki i ka decomposition like ʻole. No laila, he ʻokoʻa nui ka ikaika o ka hopena o nā laʻana ʻelua, a ʻoi aku ka kiʻekiʻe o ka ikaika o ka hopena o ka hoʻohālike hoʻoheheʻe ʻana. ʻO ka PC i ka wai (ʻoi aku ka nui o ka wai ma mua o 0.03%) a me ka wela kiʻekiʻe (ʻoi aku ka kiʻekiʻe o ka mahana ma mua o 150 ℃) ma lalo o ka hoʻohaʻahaʻa maʻalahi, no laila i ka hui ʻana a i ʻole ka hoʻomaloʻo ʻana ma mua o ka hoʻomaloʻo ʻana, pono e pale i nā lubricants stearic acid i hui pū ʻia, i ʻole e hoʻopilikia i ka. ka hana ʻana o nā huahana.
