1. Ubucucike buke no kuzura cyane
Ubucucike bwa reberi ya Ethylene propylene ni ubwoko bwa reberi yo hepfo, n'ubucucike bwayo ni 0.87.Byongeye kandi, amavuta menshi arashobora kuzuzwa no kuzuza ibyongeweho, bityo igiciro cyibicuruzwa bya reberi gishobora kugabanuka, kandi ibibi byigiciro kinini cyibikoresho bya reberi mbisi ya Ethylene-propylene.Kuri reberi ya Ethylene-propylene ifite agaciro ka Mooney, ingufu z'umubiri na mashini zirashobora kugabanuka nyuma yo kuzura cyane.ntabwo ari binini.
2. Kurwanya gusaza
Rubber ya Ethylene-propylene ifite uburyo bwiza bwo guhangana nikirere, kurwanya ozone, kurwanya ubushyuhe, aside na alkali, kurwanya imyuka y’amazi, guhagarara neza kwamabara, ibikoresho byamashanyarazi, kuzuza amavuta hamwe nubushyuhe bwicyumba.Ibikoresho bya reberi ya Ethylene-propylene birashobora gukoreshwa igihe kirekire kuri 120 ° C, kandi birashobora gukoreshwa mugihe gito cyangwa rimwe na rimwe kuri 150-200 ° C.Ongeramo imiti ikwiye yo kurwanya gusaza irashobora kongera ubushyuhe bwa serivisi.EPDM reberi ihujwe na peroxide irashobora gukoreshwa mubihe bibi.Mugihe cyimiterere ya ozone ya 50pphm no kurambura 30%, reberi ya EPDM irashobora kugera hejuru ya 150h idacitse.
3. Kurwanya ruswa
Bitewe no kubura polarite hamwe nubushyuhe buke bwo kutuzuza reberi ya Ethylene-propylene, ifite imbaraga zo kurwanya imiti itandukanye ya polar nka alcool, acide, alkalis, okiside, firigo, ibikoresho byogajuru, amavuta y’inyamanswa n’ibimera, ketone n’amavuta, nibindi. ;Ariko mumashanyarazi ya alifatique na aromatique (nka lisansi, benzene, nibindi) hamwe no guhagarara nabi mumavuta yubutare.Imikorere nayo izagabanuka mubikorwa birebire bya acide yibanze.
4. Kurwanya imyuka y'amazi
Rubber ya Ethylene-propylene ifite imbaraga zo guhangana n’umwuka w’amazi kandi bivugwa ko iruta ubushyuhe bwayo.Mu cyuka gishyushye kuri 230 ° C, nta gihinduka kigaragara nyuma yamasaha 100.Mubihe bimwe, fluororubber, silicone reberi, fluorosilicone rubber, butyl rubber, nitrile reberi, na reberi karemano bizagenda byangirika kugaragara nyuma yigihe gito ugereranije.
5. Kurwanya amazi ashyushye
Rubber ya Ethylene-propylene nayo ifite imbaraga zo kurwanya amazi ashyushye, ariko ifitanye isano rya hafi na sisitemu zose z’ibirunga.Rubber ya Ethylene-propylene hamwe na dimorpholine disulfide na TMTD kuko sisitemu y’ibirunga idafite impinduka nke mumiterere yubukanishi nyuma yo gushirwa mumazi ashyushye kuri 125 ° C mumezi 15, kandi igipimo cyo kwaguka ni 0.3% gusa.
6. Ibikoresho by'amashanyarazi
Rubber ya Ethylene-propylene ifite ibikoresho byiza byo gukwirakwiza amashanyarazi no kurwanya corona, kandi ibikoresho byayo byamashanyarazi birarenze cyangwa hafi ya reberi ya styrene-butadiene, chlorosulfonated polyethylene, polyethylene na polyethylene.
7. Elastique
Kubera ko nta kintu gisimbuza polar mu miterere ya molekuline ya reberi ya Ethylene-propylene, ingufu zifatika za molekile ni nkeya, kandi urunigi rwa molekile rushobora gukomeza guhinduka mu buryo bwagutse, rukurikira nyuma ya reberi karemano na reberi ya butadiene, kandi irashobora gukomeza ku bushyuhe buke.
8. Kwizirika
Bitewe no kubura amatsinda akora muburyo bwa molekuline ya rebero ya Ethylene-propylene, ingufu zifatika ziri hasi, kandi reberi iroroshye kumera, kandi kwishyira hamwe no gufatana ni bibi cyane.
Hebei CONQI VEHICLE FITTINGS Co., Ltd nisosiyete yitangiye gukora no gukwirakwiza ibinyabiziga byo mu bwoko bwa reberi, imashini ya EPDM, ibyiciro by’ibiribwa hamwe na pvc hose nibindi bifite uburambe bukomeye bwo kubyaza umusaruro, ikoranabuhanga rigezweho kandi rifite ubumenyi bwuzuye kandi bwubumenyi.Mu mwaka wa 2009, isosiyete yarangije umusaruro w’inganda ingana na miliyoni 10.01 Yuan kandi irangiza umusoro w’ububiko ungana na 250 000 000.Bose bahujwe na OEM zirenga 30 zo mu gihugu nka Jinlong, Yutong, Ankai, na Zhongtong, hamwe n'amashami mpuzamahanga ya Volvo n'Ubuhinde, Nouvelle-Zélande, Tayilande, Tayiwani, Polonye, Isiraheli, Ubwongereza, Misiri, Espagne, Turukiya, Burezili, Singapore, Ubudage hamwe n’ibihugu n’uturere birenga 20 byabonye ibikoresho byunganira.Twisunze amahame y "gukomeza gutera imbere, kuba indashyikirwa, ubuziranenge buhebuje, no guhaza abakiriya", dufata cyane cyane ikoranabuhanga mpuzamahanga n’amakuru agezweho ku bicuruzwa, duhora dushushanya kandi dutezimbere ibicuruzwa bishya, kandi dutanga abakiriya.
