Kedu ihe njiri mara nke roba?

1. Ọnọdụ dị ala na ebe dị elu
Mpempe akwụkwọ nke etylene-proplenenenenenenenenenenenenene bụ rọba na obere nju oyi, ya na njupụta 0.87. Na mgbakwunye, enwere ike jupụta na nnukwu mmanụ na EPDM.
Na-agbakwunye frees nwere ike belata ọnụ ahịa roba ma mejupụta ọnụahịa dị elu nke ethylene profaịlụ roba roba. Maka roo proreslene proresylene nke nwere ezigbo nri Money bara, nke anụ ahụ na nke arụ ọrụ nke na-ebelata ike na-ejupụta.

2. Ngugide na-emegide
Mpempe akwụkwọ nke etylene-propylene nwere oke nguzosi ike, iguzogide nguzogide, mgbochi mmiri, akụrụngwa na-ejupụta na mmiri na ụlọ. Enwere ike iji ngwaahịa ylene-propylene ogologo oge na 120 Celsius C, enwere ike iji ya na nkenke ma ọ bụ na 150-200 Celsius C. Na-agbakwunye antioxidants dị mma nwere ike iwepụta okpomọkụ ya. EPDM RB ROB ROB Crow-jikọtara ya na peroxide nwere ike iji n'okpuru ọnọdụ jọgburu onwe ya. Mpempe akwụkwọ EPDM nwere ike iru ihe karịrị 150h na-enweghị ịgbaji n'okpuru ọnọdụ nke ịta 50phm na 30% ịgbatị.

3. Nkwụsị Corrosion
N'ihi na etylene profanet roo profane na-enweghị polaration na ogo dị ala, ọ nwere ezigbo nguzogide ọgwụ polir dị iche iche, acid, na-egbu, na Ketones na mmanụ na-acha ụtọ. Mana o nweghi nkwụsi ike na mgbazinye abụba na nke aromatic (dị ka mmanụ ala, benzene, wdg) na mmanụ ịnweta. Ọrụ ahụ ga-agbadata n'okpuru ogologo oge nke acid acid. Na ISO / ruo 7620, ihe fọrọ nke nta ka ọ bụrụ 400 ụdị 400 na kemịkalụ na-egbu egbu na-egosi ihe omuma ha, na mmetụta nke kemịkalụ ha na-eme na ngụkọta roba.

Olu olu na-agwọ ọnụego /% ike na-agbada uru dị na arụmọrụ
1 <10 <10 obere ma ọ bụ mba
2 10-20 <20 pere mpe
3 30-60 <30 ọkara
4> 60> 30 siri ike

4. Na-eguzogide mmiri
Mpempe akwụkwọ nke etylene-propylene toro eto nwere nnukwu mmiri vepo na-eguzogide ma na-eme atụmatụ ịdị mma karịa iguzogide ọkụ ya. Na 230 ℃ sọks subheated, ọdịdị EPDM dịtụbeghị mgbe ihe fọrọ nke nta ka ọ bụ 100h. Agbanyeghị, n'okpuru otu ọnọdụ, roba roba, roba roba, roba fluosililinine, rọba na-efe efe, roba roba, na roba eke na-emebi emebi dị njọ n'ọdịdị mgbe obere oge.

5. Ntughari mmiri nke Superhea
Mpempe akwụkwọ nke etylene-propylene nwekwara ike iguzogide mmiri na-enweghị mma, mana ọ bụ njikọ chiri anya na usoro ọ bụla. Ahịhịa-romanine na dimerpholine na-enwe ike ịmịnye na TMTD dị ka usoro dị iche iche na 125 Celsius.

6. Ọrụ eletriki
Mpempe akwụkwọ nke etylene-propylene nwere ezigbo mkpuchi mkpuchi eletrik na ntuli aka ya dị mma karịa ma ọ bụ nso roonene, chlorosulfonated polyethylene, polyethylene na polyethylene ogidi.

7. Mgbanwe
N'ihi na enweghị ndị nọ n'ọkpụkpụ polar na molecular nke roba nke etylene-propylene dị ala, nke abụọ nwere ike ịdị nkọ na mbara igwe na nke na-enwe okpomọkụ na obere okpomọkụ.

8. Adhesion
Otu roba roba na-enweghị atụ, enweghị otu dị iche iche na-arụ ọrụ n'ihi ihe owuwu ya ma nwee ike coheda ike. Na mgbakwunye, roba dị mfe oge ntoju, yana nnweta onwe ya na ngwa onwe ya na ngwakọta nke na-adịchaghị mma.
