EPDM (Ethylene Propylene Diene Monomer) waa copolymer ethylene, propylene iyo qadar yar oo ah diene aan isku xidhnayn.Waa nooc ka mid ah caagga ethylene propylene.Halabuurka, kaliya waxa ku jira bonds double unsaturated in silsilad dhinaca, sidaas darteed waxa uu leeyahay iska caabin gabow heer sare ah sida iska caabin ozone, kulaylka caabbinta, iyo cimilada caabbinta, oo waxaa si ballaaran loo isticmaali karaa in qaybaha baabuurta, alaabta biyuhu aan dhismaha, silig iyo fiilada galalka, kulaylka Tuubooyinka adkaysiga u leh, cajaladaha, Baabuurta shaabadood iyo goobo kale.
Tilmaamaha ugu muhiimsan ee EPDM waa iska caabbinta oksaydhka sare, caabbinta ozone iyo caabbinta daxalka.Maadaama EPDM ay ka tirsan yihiin qoyska polyolefin, waxay leedahay sifooyin vulcanization ah oo aad u fiican.Dhammaan caagadaha dhexdooda, EPDM waxay leedahay cufis-jiidad gaar ah oo ugu hooseeya waxayna nuugi kartaa xaddi badan oo buuxinyaal iyo saliid ah oo saameyn yar ku leh guryaha, si xeryahooda caagga ah ee jaban loo sameeyo.
Rabadhka EPDM waa terpolymer ethylene, propylene iyo dienes aan isku xidhnayn.Dienes waxay leeyihiin qaab dhismeed gaar ah.Inta lagu jiro fal-celinta copolymer-ka, hal bond oo labanlaab ah oo firfircoon ayaa ka qaybqaadanaya falcelinta, halka labanlaab-jibbaaran ee soo hadhay ee leh hawl yar ay ku hadhsan tahay silsiladda molecular copolymer oo ah barta unsaturation ee sahayda.Sulfur vulcanization ayaa la isticmaalay.Kaliya mid ka mid ah labada curaarta ayaa la koobi karayn karaa, dammaanad labajibbaaran oo aan dhergin ayaa inta badan loo isticmaalaa isku xirka.Midka kale ee aan dheregsanayn ma noqon doono laf-dhabarta polymer, kaliya silsilado dhinac ah.Silsiladda polymer-ka ugu weyn ee EPDM si buuxda ayaa loo buuxiyey.Hantidani waxay EPDM ka dhigaysa mid u adkaysata kulaylka, iftiinka, ogsijiinta, iyo gaar ahaan ozone.EPDM dabeecad ahaan aan dabaylaha ahayn, adkaysi u leh xalalka polar-ka iyo kiimikooyinka, waxay leedahay nuugista biyaha hoose, waxayna leedahay sifooyin dahamiya oo wanaagsan.
Hebei CONQI VEHICLE FITTINGS Co., Ltd waa shirkad u heellan inay soo saarto oo qaybiso tuubada caagga ah ee baabuurta, tuubada EPDM, tuubada heerka cuntada iyo tuubada pvc iwm oo leh khibrad wax soo saar qani ah, tignoolajiyada wax soo saarka sare leh iyo nidaamka maaraynta tayada dhamaystiran iyo sayniska.Sannadkii 2009, shirkaddu waxay dhamaystirtay wadarta qiimaha wax soo saarka warshadaha oo dhan 10.01 milyan yuan waxayna dhamaystirtay cashuur bakhaar oo dhan 250,000 yuan.Dhammaantood waxay ku habboon yihiin in ka badan 30 OEM-yada gudaha ah sida Jinlong, Yutong, Ankai, iyo Zhongtong, iyo laamo caalami ah oo Volvo iyo India, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Masar, Spain, Turkey, Brazil, Singapore, Germany iyo in ka badan 20 waddan iyo gobollo ayaa helay tas-hiilaad taageero ah.U hoggaansanaanta mabda'a "horumar joogto ah, heer sare, tayo aad u wanaagsan, iyo qanacsanaanta macaamiisha", waxaan si taxadar leh u qabsanaa tignoolajiyada caalamiga ah ee ugu dambeeyay iyo macluumaadka badeecada, si joogto ah u naqshadeyna oo u horumarinayna alaabooyin cusub, waxaana siinaa macaamiisha.
