(1) Mphamvu ya zipangizo
Mitundu yosiyanasiyana ya PC ndi ABS resin blend ya alloy imakhala ndi kusiyana kwakukulu pakuchita. Zitha kuwoneka kuchokera ku Chithunzi 6-22 kuti mphira wapamwamba kwambiri amathandizira mphamvu ya machitidwe a PC / ABS, koma amawononga kwambiri machitidwe ogwirizana pakati pa magawo, motero kuchepetsa mphamvu zowonongeka za alloy. Chifukwa chake, kusankha ABS yokhala ndi mphira yoyenera sikungowonjezera mphamvu yakuphatikiza, komanso kumapangitsanso mphamvu yopindika mogwirizana. Pamene ABS yokhala ndi mphira yotsika ikagwiritsidwa ntchito, mphamvu yopindika ya aloyiyo imawonekera kupititsa patsogolo. Kuonjezera apo, acrylonitrile yapamwamba, otsika mphira okhutira ndi kulemera kwa maselo ABS amatha kusintha kutentha kwa alloy.
(2) Chikoka cha PC / ABS kuphatikiza chiŵerengero pa katundu wa aloyi
Kugwirizana ndi makina a PC/ABS blend system amagwirizana mwachindunji ndi zomwe zili mu gawo lililonse mu dongosolo. Cao Mingan et al. adapeza ma aloyi osiyanasiyana a PC/ABS okhala ndi mawonekedwe osiyanasiyana posintha chiŵerengero chosakanikirana cha PC ndi ABS resin. Katundu wa PC/ABS aloyi ali ndi ubale wamzere ndi zomwe zili mu ABS, ndipo pafupifupi zimamvera zowonjezera. Makhalidwe onse a PC/ABS alloy ali pakati pa PC ndi ABS, ndipo mphamvu yamphamvu imakhala ndi mphamvu ya superadditivity (ie synergy effect) ndi zotsatira za antagonism ndi gawo.
(3) Zotsatira za gawo lachitatu
Kukana kutentha ndi kukhazikika kwamafuta a PC/ABS aloyi kumatha kuwongolera powonjezera benzothiazole ndi polyimide. The fluidity wa PC/ABS aloyi akhoza kusintha powonjezera processing modifiers monga ethylene oxide/propylene oxide block copolymer, MMA/St copolymer ndi olefin/acrylic viniga copolymer. Kuonjezera apo, pofuna kupititsa patsogolo mphamvu zophatikizana za PC/ABS aloyi jakisoni, PMMA, SAN, SBR, acrylic viniga elastomer, low density polyolefin, ethylene/acrylic viniga/acetic acid, ethylene (vinegar) copolymer, PC/ethylene block. kapena kumezanitsa copolymer ndi zinthu zina nthawi zambiri zimawonjezeredwa.
(4) Zotsatira zaukadaulo waukadaulo
Zida zophatikizira za PC ndi ABS zitha kusankha kuchokera pawiri wononga extruder ndi screw extruder imodzi yokhala ndi chosakanizira chokhazikika. Jong Han Chun amakhulupirira kuti zotsatira za kukankha extruder mosalekeza ndi abwino. Pankhani yosakanikirana, zotsatira za kusakaniza kwachiwiri zimakhala bwino. Komabe, mu dongosolo lachiwiri lophatikizana, gawo la zipangizozo ziyenera kutulutsidwa kawiri pa kutentha kwakukulu, zomwe zimakhala ndi mphamvu zambiri, zosavuta kusokoneza zipangizo ndi kuchepetsa katundu wa alloy.
Njira yowumba imakhalanso ndi chikoka chachikulu pa morphology ndi kapangidwe ka PC/ABS alloy. Mwachitsanzo, chitsanzo chopangidwa ndi kukanikiza pulasitiki akhoza bwino kukhala ndi microstructure heterogeneous kubalalitsidwa boma opangidwa ndi aloyi kusanganikirana, pamene jekeseni akamaumba, pa mlingo mkulu kukameta ubweya, ndi kubalalitsidwa boma kusintha ndi kufika monyanyira yunifolomu kuwonongeka. Choncho, mphamvu ya mphamvu ya zitsanzo ziwirizo imakhala ndi kusiyana kwakukulu, ndipo mphamvu ya tsinde la tsinde lachitsulo ndilokwera kwambiri. PC m'madzi (madzi okhutira ndi aakulu kuposa 0.03%) ndi kutentha (kutentha ndi apamwamba kuposa 150 ℃) pansi mosavuta kuwonongeka, kotero mu ankasakaniza kapena akamaumba pamaso kuyanika ayenera kupewa mafuta asidi osakaniza osakaniza, kuti asakhudze magwiridwe antchito.
