Ibintu bigira ingaruka kumiterere ya PCABS

(1) Ingaruka z'ibikoresho fatizo

Ibirango bitandukanye bya PC na ABS resin ivanze ya alloy ifite itandukaniro rinini mubikorwa.Birashobora kugaragara kuva ku gishushanyo cya 6-22 ko ibinini bya reberi byongera imbaraga za sisitemu ya PC / ABS, ariko bikangiza cyane imyitwarire ya capacitance hagati yicyiciro, bityo bikagabanya imiterere ya tensile ya alloy.Kubwibyo, guhitamo ABS hamwe nibikoresho bya reberi ntibishobora gusa kunoza imbaraga zingaruka zuruvange, ahubwo binongerera imbaraga imbaraga zunamye hamwe.Iyo ABS ifite reberi nkeya ikoreshwa, imbaraga zunama za alloy zizagaragara hamwe.Byongeye kandi, acrylonitrile nyinshi, ibirimo reberi nkeya hamwe nuburemere buke bwa molekile ABS irashobora kunoza ubushyuhe bwumuti.

(2) Ingaruka ya PC / ABS igereranya ryimiterere kumiterere ya alloy

Ubwuzuzanye hamwe nubukanishi bwa PC / ABS bivanga sisitemu bifitanye isano itaziguye nibiri muri buri kintu muri sisitemu.Cao Mingan n'abandi.yabonye PC / ABS ibinyobwa bitandukanye bifite imiterere itandukanye muguhindura igipimo cyo kuvanga PC na ABS resin.Imiterere ya PC / ABS ivanze ifite umurongo ugereranije nibiri muri ABS, kandi hafi yubahiriza inyongera.Imiterere rusange ya PC / ABS ivanze iri hagati ya PC na ABS, kandi imbaraga zingaruka zigira ingaruka zidasanzwe (ni ukuvuga imbaraga za synergy) hamwe ningaruka ya antagonism hamwe nikigereranyo.

(3) Ingaruka yikintu cya gatatu

Kurwanya ubushyuhe hamwe nubushyuhe bwa PC / ABS alloy birashobora kunozwa wongeyeho benzothiazole na polyimide.Amazi ya PC / ABS alloy arashobora kunozwa hiyongereyeho uburyo bwo gutunganya nka Ethylene oxide / propylene oxyde block copolymer, MMA / St copolymer na olefin / acrylic vinegar copolymer.Mubyongeyeho, murwego rwo kunoza imbaraga zihuriweho nibicuruzwa byatewe inshinge za PC / ABS, PMMA, SAN, SBR, acarike vinegere elastomer, polyolefin yuzuye, Ethylene / acrylic vinegere / acide acike, Ethylene (vinegere) copolymer, PC / Ethylene block cyangwa gushushanya copolymer nibindi bintu mubisanzwe byongeweho.

(4) Ingaruka zikoranabuhanga ritunganya

Ibikoresho byo kuvanga PC na ABS birashobora guhitamo muri ekstruder ya twin screw na extruder imwe imwe hamwe na mixer static.Jong Han Chun yizera ko ingaruka zo gukomeza gukata extruder ari nziza.Kubijyanye no kuvanga uburyo, ingaruka zo gutondekanya-kabiri ni nziza.Nyamara, muburyo bwa kabiri buvanze, igice cyibikoresho bigomba gusubirwamo kabiri mubushyuhe bwinshi, bufite ingufu nyinshi, byoroshye gutesha agaciro ibikoresho no kugabanya imiterere yumuti.

Uburyo bwo kubumba nabwo bugira uruhare runini kuri morphologie n'imiterere ya PC / ABS.Kurugero, icyitegererezo cyakozwe mugukanda plastike kirashobora gukomeza neza microstructure ya heterogeneous dispersion leta ikorwa no kuvanga imvange, mugihe kubumba inshinge, kumuvuduko mwinshi, leta ikwirakwiza ihinduka kandi ikagera kubora kimwe.Kubwibyo, imbaraga zingaruka zintangarugero zombi zifite itandukaniro rinini, kandi imbaraga zingaruka za compression molding sample ni ndende.PC mumazi (ibirimo amazi arenze 0,03%) hamwe nubushyuhe bwo hejuru (ubushyuhe buri hejuru ya 150 ℃) mugihe cyo kwangirika byoroshye, kubwibyo kuvanga cyangwa kubumba mbere yo gukama, bigomba no kwirinda amavuta ya acide acide ivanze, kugirango bitagira ingaruka kuri imikorere y'ibicuruzwa.
