Kedu ihe bụ EPDM ihe? -Ntụle omimi nke njirimara na ngwa nke roba EPDM
EPDM (ethylene-propylene-diene monomer) bụ rọba sịntetik nwere ihu igwe dị mma, ozone na nguzogide kemịkalụ, a na-ejikwa ya n'ọtụtụ ụgbọ ala, ihe owuwu, ngwa elektrọn na ụlọ ọrụ ndị ọzọ. Tupu ịghọta ihe EPDM mere, ọ dị mkpa ịghọta usoro ihe omimi ya pụrụ iche na usoro mmepụta ya iji ghọta nke ọma njirimara na ojiji ya.
1. Ngwakọta kemịkalụ na usoro ihe omimi nke EPDM
EPDM rọba nwetara aha ya site na isi ihe mejupụtara ya: ethylene, propylene na diene monomers. Ndị monomers ndị a na-etolite ụdọ polymer na-agbanwe site na mmeghachi omume copolymerisation. Ethylene na propylene na-enye ezigbo okpomọkụ na nguzogide oxidation, ebe diene monomers na-ekwe ka EPDM jikọọ ya site na vulcanisation ma ọ bụ peroxide, na-abawanye ike na ịdịte aka nke ihe ahụ.
2. Isi arụmọrụ njirimara nke EPDM
N'ihi ihe mejupụtara kemịkalụ ya pụrụ iche, EPDM nwere ọtụtụ ihe mara mma nke na-eme ka ọ pụta ìhè n'ọtụtụ ebe. na-enweghị mmebi.EPDM nwekwara ezigbo nguzogide ozone, nke na-enye ya ohere ịnọgide na-arụ ọrụ ya na ọnọdụ gburugburu ebe obibi siri ike na-enweghị mgbawa.
Akụkụ ọzọ dị mkpa bụ nguzogide kemịkalụ ya, ọkachasị acid, alkalis na ihe mgbaze dị iche iche. Ya mere, a na-ejikarị EPDM eme ihe n'ọnọdụ ndị chọrọ ikpughe kemịkalụ ogologo oge.EPDM nwere okpomọkụ dị iche iche na-arụ ọrụ, ọ pụkwara ịrụ ọrụ nke ọma n'etiti -40 ° C na 150 ° C, nke na-eme ka ọ bụrụ nke a na-ejikarị eme ihe na ụgbọala. ụlọ ọrụ, dị ka windo akara, radiator hoses, wdg.
3. Ngwa EPDM na ụlọ ọrụ dị iche iche
A na-ekwu na ojiji EPDM juru ebe niile bụ n'ụdị ya dị iche iche na ihe anụ ahụ mara mma. N'ụlọ ọrụ ụgbọ ala, a na-ejikarị EPDM eme ihe n'ịmepụta akara, akara ọnụ ụzọ, mkpuchi ikuku na mmiri ọkụ. N'ihi okpomọkụ ha na nkwụsị nke ịka nká, ihe ndị a na-ejigide elasticity na ọrụ ha ruo ogologo oge, na-eme ka ndụ ọrụ nke ụgbọ ala dịkwuo elu.
N'ime ụlọ ọrụ ihe owuwu, a na-eji EPDM eme ihe n'ọtụtụ ebe na mkpuchi mkpuchi ụlọ, ọnụ ụzọ na windo na ngwa ndị ọzọ chọrọ mkpuchi mmiri na mgbochi UV. Nkwụsi ike ihu igwe ya dị mma na mgbanwe na-eme ka nkwụsi ike na nhazi nke ụlọ na-arụ ọrụ. EPDM na-ejikwa ihe mkpuchi nke wires na eriri, na-enye ezigbo mkpuchi ọkụ eletrik na nguzogide kemịkalụ.
4. EPDM nchekwa gburugburu ebe obibi na mmepe na-adigide
N'ọnọdụ dị ugbu a nke chọrọ nchekwa gburugburu ebe obibi na-esiwanye ike, EPDM na-enwekwa nchegbu n'ihi nchekwa gburugburu ebe obibi na ikike mmepe ya. EPDM bụ ihe a na-emegharịgharị, usoro mmepụta adịghị emerụ ahụ gas na mkpofu, n'ikwekọ na mkpa ọha mmadụ nke taa maka nchebe gburugburu ebe obibi. Site n'ịkwalite usoro mmepụta ihe na-aga n'ihu, a na-ejikwa nwayọọ nwayọọ na-ebelata ike na ihe onwunwe nke EPDM, na-enye aka na mmepe mmepe nke ụlọ ọrụ ahụ.
Mmechi
Kedu ihe bụ EPDM ihe? Ọ bụ ihe roba sịntetị na-arụ ọrụ nke ọma na ọtụtụ ngwa ngwa. Site na nguzogide ihu igwe ya, nguzogide kemịkalụ na enyi na gburugburu ebe obibi, ọ na-arụ ọrụ dị mkpa na ụlọ ọrụ dị iche iche. Ma n'ụlọ ọrụ ụgbọ ala, ụlọ ọrụ ihe owuwu, ma ọ bụ mpaghara eletriki na eletrọnịkị, EPDM abụrụla nhọrọ ihe dị mkpa n'ihi arụmọrụ ya pụtara ìhè.
