He aha ka mea EPDM? - Ka nānā ʻana i nā hiʻohiʻona a me ka hoʻohana ʻana o ka lāʻau EPDM
ʻO ka EPDM (ethylene-propylene-diene monomer) he lāʻau synthetic me ka maikaʻi o ka weathering, ka ozone a me ke kūpaʻa kemika, a hoʻohana nui ʻia i nā kaʻa, kūkulu, uila a me nā ʻoihana ʻē aʻe. Ma mua o ka hoʻomaopopo ʻana i ka mea i hana ʻia ai ka EPDM, pono e hoʻomaopopo i kāna ʻano molekala kūikawā a me ke kaʻina hana hana i mea e hoʻomaopopo maikaʻi ai i kāna mau waiwai a me kāna hoʻohana.
1. Hoʻohui kemika a me ka molecular structure o EPDM
Loaʻa ka inoa ʻo EPDM rubber mai kāna mau mea nui: ethylene, propylene a me diene monomers. Hoʻokumu kēia mau monomer i nā kaulahao polymer elastic ma o nā hopena copolymerization. Hāʻawi ka Ethylene a me propylene i ka wela maikaʻi a me ka pale ʻana, ʻoiai nā monomers diene e ʻae iā EPDM e hoʻopili ʻia e ka vulcanization a i ʻole peroxide, e hoʻonui hou i ka ikaika a me ka lōʻihi o ka mea.
2. Nā hiʻohiʻona hana nui o EPDM
Ma muli o kona ʻano kemika kū hoʻokahi, loaʻa iā EPDM nā ʻano waiwai maikaʻi loa e kū ai i nā ʻano ākea ākea. me ka deterioration.EPDM maikaʻi hoʻi ke kū'ē ozone, e hiki ai ke mālama i kāna hana i nā kūlana kūlohelohe koʻikoʻi me ka ʻole o ka pohā.
ʻO kekahi hiʻohiʻona koʻikoʻi kona kūpaʻa kemika, ʻoi aku hoʻi i nā waikawa, alkalis a me nā mea hoʻoheheʻe polar like ʻole. No laila, hoʻohana pinepine ʻia ʻo EPDM i nā kūlana e pono ai ka ʻike lōʻihi i nā kemika. ʻoihana, e like me nā sila puka makani, nā hoses radiator, etc.
3. Nā noi EPDM ma nā ʻoihana like ʻole
Hoʻohana ʻia ka hoʻohana nui ʻana o EPDM i kāna versatility a me nā waiwai kino maikaʻi. I ka ʻoihana kaʻa, hoʻohana pinepine ʻia ʻo EPDM i ka hana ʻana i nā sila, nā sila puka, nā wipers windscreen a me nā hoses radiator. Mahalo i ko lākou wela a me ke kūpaʻa ʻelemakule, mālama kēia mau mea i ko lākou elasticity a me ka hana no ka manawa lōʻihi, e hoʻonui ai i ke ola lawelawe o ke kaʻa.
I ka ʻoihana hana, hoʻohana nui ʻia ʻo EPDM i ka pale ʻana o ka hale, nā pani puka a me nā puka makani a me nā noi ʻē aʻe e pono ai ka pale wai a me ka pale UV. ʻO kona kūpaʻa maikaʻi a me ka maʻalahi e hōʻoia i ka paʻa o ka hoʻolālā a me ka hoʻopaʻa ʻana i ka hana o nā hale. Hoʻohana pū ʻia ʻo EPDM i nā mea sheathing o nā uea a me nā kaula, e hāʻawi ana i ka hana insulation uila maikaʻi loa a me ke kūpaʻa kemika.
4. EPDM palekana kaiapuni a me ka hoʻomohala mau
I ka pōʻaiapili o kēia manawa o nā koi palekana kaiapuni, hopohopo pū ʻia ʻo EPDM ma muli o kona palekana kaiapuni a me ka hiki ke hoʻomohala hoʻomau. ʻO ka EPDM he mea hiki ke hana hou ʻia, ʻoi aku ka liʻiliʻi o ke kaʻina hana i nā kinoea a me nā ʻōpala, e like me ka pono o ke kaiāulu o kēia lā no ka mālama ʻana i ke kaiapuni. Ma o ka hoʻomau mau ʻana o ke kaʻina hana, hoʻemi ʻia ka ikehu a me ka hoʻohana waiwai o EPDM, e hāʻawi ana i ka hoʻomohala mau o ka ʻoihana.
Ka hopena
He aha ka mea EPDM? He mea synthetic rubber me ka hana maikaʻi loa a me ka nui o nā noi. Me kona pale ʻana i ke aniau, ka pale kemika a me ke aloha kaiapuni, he hana koʻikoʻi ia ma nā ʻoihana like ʻole. Inā i loko o ka ʻoihana kaʻa, ka ʻoihana kūkulu, a i ʻole ka uila a me ka uila, ua lilo ʻo EPDM i mea koho waiwai nui ma muli o kāna hana koʻikoʻi.
