Hebei conqi Auto Parts Co., Ltd. waxay leedahay 10 sano oo waayo-aragnimo ah oo ku saabsan soo saarista caagga iyo alaabada caagga ah si ay kula wadaagto faa'iidooyinka iyo faa'iido darrada tuubooyinka EPDM: caabbinta gabowga, waxqabadka korantada korantada iyo waxqabadka caabbinta ozone ayaa ah mid aad u fiican.Iska caabin cimilo oo heer sare ah, caabbinta ozone, caabbinta kulaylka, caabbinta acid iyo alkali, caabbinta uumiga biyaha, xasilloonida midabka, guryaha korantada, buuxinta saliidda iyo dareeraha heerkulka caadiga ah ee kiimikooyinka kala duwan ee sida khamriga, acids, alkalis, oxidants, qaboojiyaha, saabuunta, xayawaanka iyo saliidaha khudradda, ketones iyo dufanku dhammaantood waxay leeyihiin iska caabin wanaagsan;si kastaba ha ahaatee, way ku xasilloon yihiin dareerayaasha alifleyda iyo udgoonka (sida shidaalka, benzene, iwm.) iyo saliidaha macdanta.Marka la eego ficilka muddada dheer ee aashitada xoogga leh, waxqabadka ayaa sidoo kale hoos u dhigi doona, caabbinta uumiga biyaha ayaa ka fiican iska caabbinta kulaylka.Uumiga kulul ee 230°C, ma jiro wax isbedel ah oo muuqaal ah kadib ku dhawaad 100 saacadood.Isla shuruudo isku mid ah, caag silikoon ah, caag fluorosilicone, caag butyl ah, caag nitrile ah, iyo caag dabiici ah ayaa la kulmi doona muuqaal ahaan sii xumaanaya muddo gaaban ka dib.Maaddaama aysan jirin wax beddelaad ah oo ku jira qaab-dhismeedka molecular ee caagga ethylene-propylene, tamarta isku-dhafka ah ee molecule waa mid hooseeya, silsiladda molecular waxay ilaalin kartaa dabacsanaanta ballaaran, oo keliya marka loo eego caagga dabiiciga ah iyo caagga butadiene, oo wali sii wadi kara. heerkulka hooseeya.Sababtoo ah la'aanta kooxaha firfircoon ee qaab dhismeedka molecular ee caagga ethylene-propylene, tamarta isku xiran ayaa hooseysa, caagguna waa sahlan tahay in uu ubaxo, is-ku-dhejinta iyo isku-duubnida wadajirka ah ayaa aad u liita.
Warshadeenu waxay soo martay tijaabooyin badan iyo wax soo saar badan, casriyaynta alaabta ceeriin iyo tignoolajiyada ayaa si tartiib tartiib ah u soo gaabisay farqiga u dhexeeya faa'iidooyinka iyo khasaarooyinka tuubooyinka epdm oo aad u deggan.Si kastaba ha ahaatee, sidoo kale waa lagama maarmaan in la doorto kuwa ugu habboon macaamiisha marka loo eego baahida macaamiisha.alaabta.
