1. Ubuninzi obuphantsi kunye nokuzaliswa okuphezulu
Ubuninzi berabha ye-ethylene propylene luhlobo lwerabha ephantsi, kwaye ukuxinwa kwayo yi-0.87.Ukongezelela, inani elikhulu leoli linokuzaliswa kwaye iifayili zinokongezwa, ngoko ixabiso leemveliso zerabha linokuncitshiswa, kwaye ukungonakali kwexabiso eliphezulu le-ethylene-propylene irabha yerabha eluhlaza inokwenziwa.I-rubber ye-ethylene-propylene enexabiso eliphezulu le-Mooney, amandla omzimba kunye nomatshini angancitshiswa emva kokuzaliswa okuphezulu.hayi mkhulu.
2. Ukumelana nokuguga
Irabha ye-ethylene-propylene inokumelana nemozulu ebalaseleyo, ukumelana ne-ozone, ukumelana nobushushu, ukuxhathisa kwe-asidi kunye ne-alkali, ukuxhathisa komphunga wamanzi, ukuzinza kombala, iipropati zombane, ukuzaliswa kweoli kunye nobushushu begumbi.Iimveliso zerabha ze-ethylene-propylene zingasetyenziselwa ixesha elide kwi-120 ° C, kwaye zingasetyenziswa okwethutyana okanye ngokuphindaphindiweyo kwi-150-200 ° C.Ukongeza i-agent echasene nokuguga inokunyusa ubushushu benkonzo yayo.Irabha ye-EPDM idityaniswe neperoxide ingasetyenziswa phantsi kweemeko ezinzima.Ngaphantsi kweemeko zoxinzelelo lwe-ozone ye-50pphm kunye nokwelula kwe-30%, i-rubber ye-EPDM inokufikelela ngaphezu kwe-150h ngaphandle kokuqhekeka.
3. Ukumelana nokubola
Ngenxa yokunqongophala kwe-polarity kunye neqondo eliphantsi le-unsaturation yerabha ye-ethylene-propylene, inokumelana kakuhle neekhemikhali ezahlukeneyo ze-polar ezifana ne-alcohols, i-acids, i-alkalis, i-oxidants, i-refrigerants, i-detergents, i-oyile yezilwanyana kunye nemifuno, i-ketones kunye namafutha, njl. ;Kodwa kwi-aliphatic kunye ne-aromatics solvents (efana ne-petroli, i-benzene, njl.) kunye nozinzo olubi kwioli ye-mineral.Ukusebenza kuya kuncipha phantsi kwesenzo sexesha elide le-asidi egxininisiweyo.
4. Ukumelana nomphunga wamanzi
Irabha ye-ethylene-propylene inokumelana nomphunga obalaseleyo wamanzi kwaye iqikelelwa ukuba ingaphezulu kunokumelana nobushushu.Kwi-steam eshushu kakhulu kwi-230 ° C, akukho tshintsho kwimbonakalo emva kweeyure eziphantse zibe yi-100.Ngaphantsi kweemeko ezifanayo, i-fluororubber, irabha ye-silicone, irabha ye-fluorosilicone, irabha ye-butyl, irabha ye-nitrile, kunye nerubha yendalo iya kuba nokuwohloka okucacileyo kwimbonakalo emva kwexesha elifutshane.
5. Ukumelana namanzi ashushu
Irabha ye-ethylene-propylene nayo inokumelana bhetele namanzi ashushu kakhulu, kodwa inxulumene ngokusondeleyo kuzo zonke iinkqubo ze-vulcanization.Irabha ye-ethylene-propylene kunye ne-dimorpholine disulfide kunye ne-TMTD njengoko inkqubo ye-vulcanization inotshintsho oluncinci kwiipropati zomatshini emva kokucwiliswa kwamanzi ashushu kakhulu kwi-125 ° C kwiinyanga ze-15, kwaye izinga lokwandiswa kwevolumu yi-0.3 kuphela.
6. Iimpawu zombane
Irabha ye-ethylene-propylene inezixhobo ezigqwesileyo zokufakelwa kombane kunye nokumelana ne-corona, kwaye iipropathi zayo zombane ziphezulu okanye zisondele kwirabha ye-styrene-butadiene, i-chlorosulfonated polyethylene, i-polyethylene kunye ne-polyethylene edibeneyo.
7. Ukolula
Ekubeni akukho zixhobo ze-polar kwisakhiwo se-molecular ye-rubber ye-ethylene-propylene, amandla adibeneyo e-molecule aphantsi, kwaye i-molecular chain chain inokugcina ukuguquguquka kuluhlu olubanzi, okwesibini kuphela kwi-rubber yendalo kunye ne-butadiene irabha, kwaye isakwazi ukugcina. kwiqondo lobushushu eliphantsi.
8. Ukuncamathela
Ngenxa yokungabikho kwamaqela asebenzayo kwisakhiwo se-molecular ye-ethylene-propylene irabha, amandla adibeneyo aphantsi, kwaye i-rubber ilula ukuqhakaza, kwaye i-self-adhesive and adhesion mutual ihlwempu kakhulu.
I-Hebei CONQI VEHICLE FITTINGS Co., Ltd. yinkampani ezinikele ekuveliseni nasekusasazeni umbhobho werabha we-auto, umbhobho we-EPDM, i-hose yebakala lokutya kunye ne-pvc hose njl njl kunye namava okuvelisa acebileyo, iteknoloji yemveliso ephezulu kunye nenkqubo epheleleyo kunye nesayensi yokulawula umgangatho.Ngo-2009, inkampani yagqiba ixabiso lemveliso ye-yuan yezigidi ezili-10.01 kwaye yagqiba irhafu ye-250, 000 ye-yuan.Zonke zihambelana nee-OEM zasekhaya ezingaphezu kwama-30 ezinje ngeJinlong, Yutong, Ankai, kunye neZhongtong, kunye namasebe aphesheya kweVolvo kunye neIndiya, New Zealand, Thailand, Taiwan, Poland, Israel, Britane, Egypt, Spain, Turkey, IBrazil, iSingapore, iJamani kunye namazwe angaphezu kwama-20 kunye nemimandla ifumene izibonelelo ezixhasayo.Ukubambelela kumgaqo "wophuculo oluqhubekayo, ukugqwesa, umgangatho obalaseleyo, kunye nokwaneliseka kwabathengi", sithatha ngokunyanisekileyo itekhnoloji yamva nje yezizwe ngezizwe kunye nolwazi lwemveliso, siyila rhoqo kwaye siphuhlisa iimveliso ezintsha, kwaye sibonelela abathengi.
