EPDM (Ethylene Propylene Diene Monomer) yog ib copolymer ntawm ethylene, propylene thiab ib tug me me ntawm cov tsis-conjugated diene.Nws yog ib hom ethylene propylene roj hmab.Kev sib xyaw, tsuas yog muaj ob daim ntawv cog lus tsis txaus ntseeg nyob rau hauv cov saw hlau sab, yog li nws muaj kev laus zoo xws li ozone tsis kam, tiv thaiv tshav kub, thiab huab cua tsis kam, thiab tuaj yeem siv dav hauv cov tsheb, cov khoom siv dej tsis zoo rau kev tsim kho, hlau thiab cable sheaths, tshav kub. -resistant hoses, tapes, Automotive seals thiab lwm yam teb.
Qhov tseem ceeb tshaj plaws ntawm EPDM yog nws cov oxidation zoo dua, ozone kuj thiab corrosion kuj.Txij li thaum EPDM belongs rau tsev neeg polyolefin, nws muaj cov yam ntxwv zoo vulcanization.Ntawm tag nrho cov roj hmab, EPDM muaj qhov qis tshaj qhov tshwj xeeb thiab tuaj yeem nqus tau ntau ntawm cov khoom ntim thiab cov roj uas muaj cov nyhuv me me ntawm cov khoom, kom cov khoom siv roj hmab qis tuaj yeem ua tau.
EPDM roj hmab yog terpolymer ntawm ethylene, propylene thiab non-conjugated dienes.Dienes muaj cov qauv tshwj xeeb.Thaum lub sij hawm cov tshuaj tiv thaiv copolymer, tsuas yog ib qho kev sib koom ua ke ntawm ob daim ntawv cog lus koom nrog cov tshuaj tiv thaiv, thaum qhov seem ob daim ntawv cog lus nrog kev ua haujlwm tsawg tseem nyob rau ntawm cov saw hlau copolymer molecular raws li qhov tsis txaus ntseeg rau kev muab khoom.Sulfur vulcanization tau siv.Tsuas yog ib qho ntawm ob daim ntawv cog lus tuaj yeem ua tau copolymerized, thiab ob daim ntawv cog lus unsaturated feem ntau yog siv los ua qhov sib txuas.Lwm yam unsaturated yuav tsis dhau los ua cov pob txha polymer, tsuas yog sab chains.Lub ntsiab polymer saw ntawm EPDM yog tag nrho saturated.Cov cuab yeej no ua rau EPDM tiv taus cua sov, lub teeb, oxygen, thiab tshwj xeeb tshaj yog ozone.EPDM yog non-polar nyob rau hauv cov xwm, resistant rau polar daws thiab tshuaj, muaj tsawg dej nqus, thiab muaj zoo insulating zog.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. yog ib lub tuam txhab mob siab rau tsim thiab faib cov roj hmab hose, EPDM hose, zaub mov qib hose thiab pvc hose thiab lwm yam nrog kev nplua nuj ntau lawm, kev tsim khoom siab heev thiab ua tiav thiab kev tswj xyuas zoo.Hauv xyoo 2009, lub tuam txhab ua tiav tag nrho cov khoom tsim tawm tus nqi ntawm 10.01 lab yuan thiab ua tiav cov se warehouse ntawm 250,000 yuan.Tag nrho cov ntawm lawv yog txuam nrog ntau tshaj 30 domestic OEMs xws li Jinlong, Yutong, Ankai, thiab Zhongtong, thiab nrog thoob ntiaj teb ceg ntawm Volvo thiab Is Nrias teb, New Zealand, Thaib, Taiwan, Poland, Ixayees, Britain, Egypt, Spain, Qaib ntxhw, Brazil, Singapore, Lub teb chaws Yelemees thiab ntau dua 20 lub teb chaws thiab cheeb tsam tau txais cov chaw txhawb nqa.Ua raws li lub ntsiab lus ntawm "kev txhim kho txuas ntxiv, kev ua tau zoo, zoo heev, thiab kev txaus siab rau cov neeg siv khoom", peb tau mob siab ntes cov cuab yeej technology thoob ntiaj teb tshiab thiab cov ntaub ntawv khoom, tas li tsim thiab tsim cov khoom tshiab, thiab muab cov neeg siv khoom.
