Zomwe zimakhudza katundu wa PCABS alloy

(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 PC/ABS, koma amawononga kwambiri machitidwe ogwirizana pakati pa magawowo, motero amachepetsa mphamvu zamagetsi za alloy.Chifukwa chake, kusankha ABS yokhala ndi mphira yoyenera sikungowonjezera mphamvu yakuphatikiza, komanso kumawonjezera mphamvu yopindika mogwirizana.Pamene ABS yokhala ndi mphira yotsika ikagwiritsidwa ntchito, mphamvu yopindika ya aloyiyo imawonekera kupititsa patsogolo.Kuphatikiza apo, acrylonitrile apamwamba, otsika mphira okhutira ndi kulemera kwa maselo ABS amatha kusintha kukana kwa kutentha kwa aloyi.

(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.Makhalidwe a PC/ABS alloy ali ndi ubale wofananira ndi zomwe zili mu ABS, ndipo pafupifupi amamvera zowonjezera.Makhalidwe onse a PC/ABS alloy ali pakati pa PC ndi ABS, ndipo mphamvu yamphamvu imakhala ndi zotsatira za 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 jekeseni wa aloyi, PMMA, SAN, SBR, acrylic viniga elastomer, low density polyolefin, ethylene/acrylic vinegar/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 ya kusakaniza mode, 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 zogwiritsira ntchito mphamvu, 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 wopangidwa 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 ziwirizi imakhala ndi kusiyana kwakukulu, ndipo mphamvu ya tsinde la psinjika akamaumba chitsanzo ndi mkulu.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 musanayambe kuyanika ayenera kupewa lubricant asidi osakaniza, kuti asakhudze magwiridwe antchito.
