EPDM papa huʻihuʻi/pepa make ʻoki ʻoki/gasket
1. Kū'ē kiʻekiʻe i kaʻelemakule
ʻO kahi kūʻē ozone maikaʻi loa - Ua ʻike ʻia ʻo EPDM ʻo "non-cracking rubber", a loaʻa iā ia ke kūpaʻa ozone maikaʻi loa ma waena o nā pulupulu kumu nui.
B ʻoi aku ka maikaʻi o ka paʻa wela.
C Ke kūpaʻa ʻelemakule maikaʻi loa - hiki ke hoʻohana ʻia no ka manawa lōʻihi ma 130 ℃, a hiki ke hoʻohana i ka manawa pōkole a i ʻole ka wā pōkole ma 150 ℃ a i ʻole ka wela kiʻekiʻe.
D Kūʻē maikaʻi i ka wā - pili i ka ʻelemakule o nā kumu i hui pū ʻia o ka māmā, ka wela, ka hau, ka makani, ka ua, ka ozone a me ka oxygen i ke kaiapuni kūlohelohe.
2. Kūʻē kemika maikaʻi loa: Ma muli o ke kūpaʻa a me ka polarity ʻole o ka EPDM ponoʻī, ʻaʻole ia e hana kemika me ka hapa nui o nā mea kemika, a ʻaʻole kūpono a ʻaʻole liʻiliʻi ka pili ʻana me nā mea polar.He kūpaʻa ia i ka waiʻona, nā waikawa (formic acid, acetic acid), nā kumu ikaika, nā mea hoʻomake (e like me H2O2, HCLO, etc.), nā mea holoi, nā aila holoholona a me nā mea kanu, nā ketones, kekahi mau momona, a me ka hydrazine.
3. ʻO ke kūpaʻa wai maikaʻi loa, ka pale ʻana i ka wela a me ka pale ʻana i ka mahu wai: ʻo ka wai he mea polar ikaika, a ʻo EPDM rubber kahi ʻano macromolecular alkanehydrazine me ka "hydrophobicity".ʻAʻohe pilina kemika ma waena o nā mea ʻelua, no laila he kūpaʻa wai maikaʻi loa, kūpaʻa overheating a me ke kū ʻana o ka mahu wai.
EPDM waiwai waiwai
ʻO nā hiʻohiʻona huahana o EPDM rubber foam sponge: Ua māhele ʻia ka huahana i loko o ka pahu pani pani a me ka ʻūhā hāmama.Hoʻokaʻawale ʻia ke kelepona i loko o ka mea hoʻoheheʻe i pani ʻia mai ke kelepona e kahi kiʻi pā, ʻaʻole i pili kekahi i kekahi.He hale kūʻokoʻa pūnaewele ia, a ʻo ka mea nui He ʻano liʻiliʻi liʻiliʻi a i ʻole liʻiliʻi liʻiliʻi micro-cell;ʻo nā pūnaewele o loko o ka mea hāmama pūnaewele e pili pū kekahi me kekahi, a pili pū kekahi me ka ʻili o waho, ʻo ia ka hale kūʻokoʻa kūʻokoʻa ʻole, ʻoi aku ka nui o nā pūnaewele a i ʻole nā puka koʻikoʻi.
Mea paʻa paʻa kelepona: maikaʻi loa ka pale ʻana i ka wā;liʻiliʻi bulk density, kiʻekiʻe waimaka ikaika;haʻahaʻa thermal conductivity;maikaʻi haʻalulu.
Mea wehe ʻia: maikaʻi loa ka pale ʻana i ka wā;pale wela kiʻekiʻe, maikaʻi haʻahaʻa haʻahaʻa haʻahaʻa;ka mālama ʻana i ka wela, ka mālama ʻana i ka wela maikaʻi;pale ʻaila polar, kūʻē kemika;ʻoi aku ka maikaʻi o ka hoʻoemi ʻana i ka wai, maikaʻi ke kani kani.
ʻO nā mea paʻa i hoʻopaʻa ʻia: hoʻohana ʻia no ka lawe ʻana i nā mea hana pololei, nā mea lapaʻau, nā puka kaʻa a me nā sila puka makani, nā mea kani a me nā mea haʻalulu;ka ea, ka hoʻopaʻa ʻana i ka pahu hau a me nā mea hoʻomāmā.ʻO nā mea hoʻoheheʻe leo no nā paia, ka mahu a me ka pale wai no nā huahana uila.
Mea wehe: E like me ke kiʻekiʻe-grade thermal insulation, shock absorption, sound absorption material, hoʻohana ʻia i nā kaʻa, air conditioners, electronics, leo hale, nā alanui, nā alahaka a me nā māla ʻē aʻe.
ʻO ka EPDM EPDM rubber ka maikaʻi o ka wā, ke kū'ē i ka mahana, ke kū'ēʻana i ka wā kahiko, ka hoʻopaʻaʻana i ka sila a me nāʻano'ē aʻe, a hiki ke hoʻohanaʻia i ka ea ea waena, ka hoʻouluʻana o ka pipeline insulation, nā pale pale, ke kani kani a me ka hoʻohaʻahaʻa leo a me nā māla'ē aʻe.
