Soo koobid:Nooc cusub oo budo ah oo loo isticmaalo in lagu wanaajiyo sifooyinka farsamada ee AS resin sida iska caabbinta saamaynta, kordhinta xoogga alaabta iyo hagaajinta waxqabadka gabowga ee alaabta - budada ASA JCS-885, oo lagu dabaqay naqshadaynta duritaanka resin AS.Waa wax soo saar ka samaysan polymerization emulsion-ka qolof ah waxayna leedahay la jaanqaad wanaagsan oo ku saabsan xabagta AS.Waxay hagaajin kartaa sifooyinka farsamada ee alaabta iyada oo aan la dhimin waxqabadka gabowga ee alaabta waxaana loo isticmaalaa qaabeynta duritaanka.

1. Hordhac
Guud ahaan, ASA resin, terpolymer ka kooban acrylate-styrene-acrylonitrile, waxaa loo diyaariyaa iyadoo lagu tallaalayo styrene iyo acrylonitrile polymers caag akril ah waxaana caadi ahaan loo isticmaalaa qaybaha elektiroonigga ah ee dibadda, qalabka dhismaha, iyo alaabta ciyaaraha sababo la xiriira sifooyinkeeda wanaagsan, oo ay ku jiraan caabbinta cimilada. , iska caabin kiimikaad, iyo karti shaqayneed.Si kastaba ha ahaatee, isticmaalka resins ASA ee alaabta u baahan midabada sida casaanka, jaalaha, cagaarka, iwm waa xaddidan tahay sababtoo ah xeryahooda styrene iyo acrylonitrile si fiican uguma tallaalaan caag acrylate inta lagu jiro diyaarinta waxayna soo bandhigaan caag acrylate ah oo ku jira, taasoo keentay midabka liidata iyo dhaldhalaalka haraaga ah.Gaar ahaan, tusmooyinka dib-u-celinta ee monomer-yada loo adeegsaday diyaarinta resin ASA waxay ahaayeen 1.460 for butyl acrylate, 1.518 ee acrylonitrile, iyo 1.590 ee styrene, sida in farqi weyn uu u dhexeeyay index refractive ee caagga acrylate loo isticmaalo sida xudunta iyo kan. index refractive ee xeryahooda meeshoodii galay.Sidaa darteed, xabagta ASA waxay leedahay sifooyin isku mid ah midab liita.Maaddaama uu xabagta ASA uu yahay mid mugdi ah oo aan fiicnayn sifooyin farsamo oo aan fiicneyn sida guryaha saamaynta iyo xoogga xajinta ee xabagta saafiga ah, tani waxay ina keenaysaa jihada R&D ee hadda iyo dariiqa R&D.
Hababka heerkulbeegga caadiga ah ee hadda la heli karo waa acrylonitrile-butadiene-styrene (ABS) polymers oo lagu daray caag sida polymers-ka butadiene.ABS polymers waxay leeyihiin awood saameyn aad u fiican xitaa heerkulka aadka u hooseeya, laakiin waxay leeyihiin cimilo liidata iyo iska caabinta gabowga.Sidaa darteed, waxaa lagama maarmaan ah in laga saaro polymers-ka ethylene ee aan saturated copolymers-ka si loogu diyaariyo resins leh awood saameyn aad u wanaagsan oo ay weheliso cimilo heer sare ah iyo caabbinta gabowga.
Budada ASA JCS-885 ee ay soo saartay shirkadeena waxay aad ugu habboon tahay AS resin, waxayna leedahay faa'iidooyinka iska caabbinta saamaynta sare leh, wax qabad heer sare ah, iska caabin cimilo oo heer sare ah, iyo korodhka xoogga alaabta.Waxa lagu dabaqaa qaabaynta duritaanka resin-ka ee AS.
2 Qiyaasta lagu taliyay
AS resin/ASA budada JCS-885=7/3, taas oo ah, 100kii qayboodba ee AS resin alloy, waxay ka kooban tahay 70 qaybood oo AS resin ah, iyo 30 qaybood oo ah budada ASA JCS-885.
3 Isbarbardhigga waxqabadka ee gudaha iyo dibadda budada caadiga ah ee ASA
1. Daawaha resin-ka AS waxa loo diyaariyey si waafaqsan qaacidada shaxda 1 ee hoose.
