Abstract:Uhlobo olusha lwempushana yenjoloba esetshenziselwa ukuthuthukisa izakhiwo zemishini ye-AS resin njengokumelana nomthelela, ukwandisa amandla omkhiqizo futhi kuthuthukise ukusebenza kokuguga komkhiqizo—i-ASA yerabha powder JCS-887, esetshenziswa ekubumbeni komjovo we-AS resin.Iwumkhiqizo we-core-shell emulsion polymerization futhi inokuhambisana okuhle ne-AS resin.Ingathuthukisa izici zemishini yomkhiqizo ngaphandle kokunciphisa ukusebenza kokuguga komkhiqizo futhi isetshenziselwa ukubumba umjovo.
Amagama angukhiye:I-AS resin, impushana yerabha ye-ASA, izakhiwo zemishini, ukumelana nesimo sezulu, ukubumba umjovo.

1 Isingeniso
Ngokuvamile, i-ASA resin, i-terpolymer ehlanganisa i-acrylate-styrene-acrylonitrile, ilungiswa ngokuxhunyelelwa ama-styrene nama-acrylonitrile polymers enjolweni ye-acrylic futhi ivame ukusetshenziswa ezingxenyeni zikagesi zangaphandle, izinto zokwakha, nezimpahla zezemidlalo ngenxa yezakhiwo zayo ezinhle, okuhlanganisa ukumelana nesimo sezulu. , ukumelana namakhemikhali, nokusebenza kahle.Kodwa-ke, ukusetshenziswa kwama-ASA resins ezintweni ezidinga imibala efana nobomvu, ophuzi, oluhlaza okotshani, njll. kunqunyelwe ngoba izinhlanganisela ze-styrene ne-acrylonitrile azixhumi ngokwanele kurabha ye-acrylate ngesikhathi sokulungiswa kwayo futhi zidalule irabha ye-acrylate ekhona kuyo, okuholela ekutheni ukungafani kombala okungalungile kanye nesicwebezelisi esisele.Ngokukhethekile, ama-indices e-refractive ama-monomers asetshenziselwa ukulungisa i-ASA resin abengu-1.460 we-butyl acrylate, 1.518 we-acrylonitrile, kanye no-1.590 we-styrene, kangangokuthi kube khona umehluko omkhulu phakathi kwenkomba ephikisayo yerabha ye-acrylate esetshenziswa njengomongo kanye Inkomba ye-refractive yama-compounds axhunyelelwe kuyo.Ngakho-ke, i-resin ye-ASA inezakhiwo ezilinganiselwe zokufanisa imibala.Njengoba inhlaka ye-ASA ingabonakali futhi ingeyona into enhle kakhulu yemishini efana nezakhiwo ezinomthelela namandla aqinile e-resin ehlanzekile, lokhu kusiletha endleleni yamanje ye-R&D kanye nomzila we-R&D.
Izingoma ezijwayelekile ze-thermoplastic ezitholakalayo njengamanje ama-polymer acrylonitrile-butadiene-styrene (ABS) ahlanganiswe nerabha njengama-polymers e-butadiene.Ama-polymer e-ABS anamandla amakhulu okuthonya ngisho nasezingeni eliphansi kakhulu lokushisa, kodwa anesimo sezulu esingesihle kanye nokumelana nokuguga.Ngakho-ke, kuyadingeka ukususa ama-ethylene polymers angagcwalisiwe kuma-graft copolymers ukuze kulungiswe ama-resin anamandla omthelela amahle kakhulu kanye nesimo sezulu esihle kakhulu nokumelana nokuguga.
I-ASA rubber powder JCS-887 ethuthukiswe inkampani yethu ihambisana kakhulu ne-AS resin, futhi inezinzuzo zokumelana nomthelela ophezulu, ukusebenza kahle kokucubungula, ukumelana nesimo sezulu esihle kakhulu, namandla omkhiqizo anda.Isetshenziswa ekubunjweni komjovo we-AS resin.
2 Umthamo onconyiwe
AS resin/ASA rubber powder JCS-887=7/3, okusho ukuthi, kuzo zonke izingxenye eziyi-100 ze-AS resin alloy, yakhiwe izingxenye ezingama-70 ze-AS resin, kanye nezingxenye ezingama-30 ze-ASA yerabha powder JCS-887.
3 Ukuqhathaniswa kokusebenza nempushana yerabha ye-ASA yasekhaya neyangaphandle
1. Ingxubevange ye-AS resin yalungiswa ngokwefomula kuThebula 1 ngezansi.

2. Izinyathelo zokucutshungulwa kwe-AS resin alloy: Hlanganisa ifomula engenhla, engeza inhlanganisela ku-granulator ukuze kuhlanganiswe ama-granules, bese ufaka ama-granules emshinini wokubumba umjovo wokubumba umjovo.
3. Hlola ukuze uqhathanise izakhiwo zemishini zamapheshana esampula ngemva kokubunjwa komjovo.
4. Ukuqhathaniswa kokusebenza phakathi kwe-ASA ye-rubber powder JCS-887 kanye namasampula angaphandle kuboniswe kuThebula 2 ngezansi.

4 Isiphetho
Ngemuva kokuqinisekiswa kokuhlolwa, i-ASA rubber powder JCS-887 eyakhiwe yinkampani yethu kanye ne-AS resin injection molding, zonke izici zemishini yemishini ziye zathuthukiswa, futhi kuzo zonke izici azikho ngaphansi kwezinye impushana yerabha ekhaya nakwamanye amazwe.
