No ke aha e hoʻohana ai i ke kāpili kāpili?
Kau ʻia e Nick P ma Pepeluali 21, '18
ʻO nā kāpili silikone kahi hui kāpili me nā mea kūlohelohe a me nā inorganic, a me ka silica fume maʻemaʻe loa e like me ʻelua mau mea nui. Loaʻa iā lākou nā ʻano he nui i loaʻa ʻole i loko o nā ʻōpala ʻē aʻe a he kuleana koʻikoʻi i nā ʻoihana he nui, e like me ka uila, uila, kaʻa, nā meaʻai, nā lāʻau lapaʻau, nā mīkini home a me nā huahana leʻaleʻa. ʻOkoʻa ka mea ʻāpana silikone mai ka lahilahi maʻamau i ke ʻano o ka mole o ka polymer o nā kaulahao lōʻihi o nā ʻāpana silikona a me oxygen ʻokoma. No laila he ʻano ʻokanika a ʻaʻano ʻole kēia polymer. Hiki i ka ʻāpana inorganic ke pale aku i ka polymer i ka mahana kiʻekiʻe a hāʻawi i nā pono uila uila maikaʻi a me ka inertness kemika, ʻoiai nā mea kūlohelohe e maʻalahi.
Nā ʻano
Heat ia'ku:
Pilikia wela nā mea kāpili silikone i ka hoʻohālikelike ʻia me nā ʻōpala maʻamau. ʻAneʻane ʻaʻohe hoʻololi o nā waiwai ma 150oC a no laila hiki iā lākou ke hoʻohana ʻaneʻane paʻa. Ma muli o kā lākou kūpaʻa wela maikaʻi e hoʻohana ākea ʻia lākou ma ke ʻano he mea no nā ʻāpana kāpili i hoʻohana ʻia i nā mahana wela.
Kūʻali anuanu:
Paa anuanu i ke kūpale ke kāpili silikona. ʻO ke kiko palupalu o nā rubber meaola maʻamau ma kahi o -20oC a -30oC. ʻO ke kiko palupalu o nā rubber silikone ma lalo o -60oC a -70oC.
Ke Kūlana Kūwaʻa:
He maikaʻi loa ke kūpale ʻana i ke aniani o nā silikona. Ma lalo o ke aniani o ka ozone e hana ʻia ma muli o ka hoʻokuʻu corona, ʻoi aku ka lahilahi o nā rubber meaola maʻamau akā ua waiho mau nā ʻāpana silikone i aneane ʻole e hoʻopilikia ʻia. ʻOiai ma lalo o ka hopena lōʻihi i ka ultraviolet a me ke anilā, noho mau ko lākou mau waiwai.
Nā Pono uila:
He maikaʻi maikaʻi nā mea hoʻoheheʻe uila a me ka paʻa i lalo o kahi ākea o nā alapine a me ka mahana. ʻAʻole ʻike ʻia ka hōʻino nui o nā ʻano ke hoʻokomo ʻia nā rubber silikone i ka wai. No laila ʻoi aku ka maikaʻi o ka hoʻohana ʻia ʻana ma ke ʻano he mau uila uila. I kekahi mau mea pīpī pīpī e kūpale loa i ka hoʻokuʻu corona a i ʻole ka uila ma kāna uila kiʻekiʻe a no laila hoʻohana nui ʻia e like me nā mea insulate no nā ʻāpana uila kiʻekiʻe.
Uila conductivity:
ʻO nā ʻāpana silikō conductive uila ka hui pū me nā uila i lawe ʻia e like me ke kalapona i hoʻohui ʻia. Loaʻa nā huahana like ʻole me ke kūʻē uila mai kekahi mau ohms-cm a i e + 3 ohms-cm. Eia kekahi, ua hoʻohālikelike ʻia nā waiwai ʻē aʻe i kēlā me nā rubber silikona maʻamau. No laila hoʻohana ākea lākou e like me nā kiko pili o nā keyboard, a puni nā mea hoʻomehana a me nā mea e sila ai no nā mea anti-static a me nā kaula uila kiʻekiʻe. Ma ke ʻano laulā, loaʻa nā uila silikone conductive uila i ke kūʻai aku ka hapanui o nā mea me ka nui o ka uila resistivity mai 1 a e + 3 ohms-cm.
Kūlana luhi:
Ma ka laulā, ʻaʻole ʻoi aku ka maikaʻi o nā rubber silikona i nā ʻōpala kūlohelohe maʻamau e pili ana i ka ikaika i ke koʻikoʻi ikaika e like me ke kūlia luhi. Eia nō naʻe, e lanakila i kēia kīnā, nā ʻōpala i 8 a 20 mau manawa ʻoi aku ka maikaʻi ma ke kūpaʻa luhi ke hoʻomohala ʻia. Hoʻohana nui ʻia kēia huahana ma nā ʻano like ʻole e like me nā keyboard o nā mīkini hana keʻena a me nā ʻāpana kāpili o nā kaʻa halihali.
Ke kūʻē ʻana i nā kukuna Radioactive:
ʻO nā rubber silikone maʻamau (dimenthyl silicone rubbers) ʻaʻole hōʻike i ke kūpaʻa maikaʻi loa i nā kukuna radioactive i ka hoʻohālikelike ʻia me nā ʻōpala ʻokanika ʻē aʻe. Eia nō naʻe nā methyl phenyl silikō rubber, me ka radical phenyl e hoʻokomo ʻia i loko o ka polymer, loaʻa iā ia ke kūpaʻa maikaʻi i nā kukuna radioactive. Hoʻohana ʻia lākou ma ke ʻano he kaula uila a me nā mea hoʻopili i nā wahi uila nukelea.
Ke kūʻē ʻana i ka mahu:
Loaʻa nā haʻahaʻa o ka wai silikone i kahi mimiki o kahi 1% ʻoiai ke komo ʻia i loko o ka wai no kahi lōʻihi. ʻAneʻane ʻole e hoʻopili ʻia ka ikaika o ka mīkini a me nā pono uila. ʻO ka maʻamau ʻaʻole e hōʻino nā rubber silikone ke hoʻopili ʻia me ka mahu, lilo ka hopena i mea nui ke hoʻonui ʻia ka puhi mahu. Haki ka Siloxane polymer ma lalo o ka māhu kiʻekiʻe ma luna o 150oC. Hiki ke hoʻoponopono ʻia kēia hanana e ka hana kāpili silikone, ke koho ʻana i nā ʻākena vulcanizing a me ka hoʻōla post.
Uila conductivity:
ʻO nā ʻāpana silikō conductive uila ka hui pū me nā uila i lawe ʻia e like me ke kalapona i hoʻohui ʻia. Loaʻa nā huahana like ʻole me ke kūʻē uila mai kekahi mau ohms-cm a i e + 3 ohms-cm. Eia kekahi, ua hoʻohālikelike ʻia nā waiwai ʻē aʻe i kēlā me nā rubber silikona maʻamau. No laila hoʻohana ākea lākou e like me nā kiko pili o nā keyboard, a puni nā mea hoʻomehana a me nā mea e sila ai no nā mea anti-static a me nā kaula uila kiʻekiʻe. Ma ke ʻano laulā, loaʻa nā uila silikone conductive uila i ke kūʻai aku ka hapanui o nā mea me ka nui o ka uila resistivity mai 1 a e + 3 ohms-cm.
Mīkiniʻopihia Hoʻonohonoho:
Ke hoʻohana ʻia nā kāpili silikone e like me nā mea kāpili no ka hoʻopili ʻana i hana ʻia i ka deformation compressive ma lalo o ke ʻano hoʻomehana, he mea nui ka hiki ke loaʻa hou. Hoʻonohonoho ʻia ka seti compression o nā rubber silikone ma luna o kahi ākea o nā mahana mai -60oC a i 250oC. ʻO ka maʻamau ka mea e pono ai i nā rubbers silikone e hoʻōla i ka lāʻau. ʻOi loa i ka hihia o nā huahana me nā hoʻonohonoho hoʻohaʻahaʻa haʻahaʻa. Makemake ʻia ka lāʻau hoʻōla a pono ke koho ʻana i nā ʻohana vulcanizing optimum maikaʻi loa.
Thermal Conductivity:
ʻO ka conductivity thermal o ka paukū silikone ma kahi o 0.5 e + 3 cal.cm.sec. C. Kēia waiwai hōʻike maikaʻi conductivity mehana no ka mea pīlali rubbers, no laila lākou e hoʻohana ai e like me nā poho wela a me nā paiehana hoʻomehana.
Tensile kiʻekiʻe a haehae Strengt:
Ma ka laulā, ʻo ka ikaika o ka waimaka o nā rubber silikone e pili ana iā 15kgf / cm. Eia nō naʻe, loaʻa nā huahana ikaika ikaika a haehae (30kgf / cm a 50kgf / cm) e ka hoʻomaikaʻi ʻana i ka polymer a me ke koho ʻana o nā mea hoʻopihapiha a me nā ʻākea hoʻohui. Hoʻohana maikaʻi ʻia kēia huahana e hana i nā hoʻoheheʻe paʻakikī, kahi e koi ai i ka ikaika o ka waimaka nui, nā ʻāpana puna me nā pale hope a me nā hoʻoheheʻe nui.
Incombustibility:
ʻAʻole wela nā ʻāpana silikone ʻoiai lākou e kau kokoke ana i ka lapalapa. Eia naʻe ke puhi lākou i ke ahi, wela mau lākou. Me ka hoʻohui ʻana o ka retardant o ka lapalapa minuke, hiki i nā rubbers silikone ke loaʻa ka incombustibility a me ka hiki ke kinai.
ʻAʻole hoʻokuʻu kēia mau huahana i kekahi uahi a i ʻole nā kinoea ʻino ke puhi lākou, no ka mea ʻaʻole lākou i loko o nā hui halogen organik i kū i nā ʻōpala maoli. No laila hoʻohana mau ʻia ia i nā mīkini uila o ka home a me nā mīkini keʻena a me nā mea no ka wahi paʻa i nā mokulele, nā subway a me nā hale o loko. Lilo lākou i huahana pono ʻole i nā ʻano palekana.
Gas Permeability:
ʻO nā membrane o nā ʻāpana silikona ka permeability ʻoi aku ka maikaʻi no nā kinoea a me ka mahu wai a ʻoi aku ka maikaʻi o ka selectivity i ka hoʻohālikelike ʻana i ka kāpiliola.
Inertness Physiological:
Hoʻomaʻamaʻa ʻole nā Rubber silikone i ka physiology. Loaʻa iā lākou nā waiwai hoihoi e like me ka mea maʻalahi ʻole i ka coagulation o ke koko. No laila ke hoʻohana ʻia nei lākou ma ke ʻano he catheters, hollow fibers a me ka puʻuwai puʻuwai puʻuwai, nā lāʻau āpau, nā lāʻau kūpina lāʻau lapaʻau a me nā aniani no ka ʻike ultrasonic.
Transparency a me ke kala:
ʻEleʻele nā rubber kūlohelohe maʻamau ma muli o ka hoʻopili ʻia ʻana o ke kalapona. E pili ana i nā rubber silikone, hiki ke hana i nā rubbers aniani loa ma o ka hoʻohui ʻana i ka silica maikaʻi i hōʻino ʻole ʻia i ka transparency kumu o ka silikona.
Ma muli o ka transparency maikaʻi loa, maʻalahi ka colouration e nā pigment. No laila hiki ke loaʻa nā huahana kala.
Nā Pono paʻa ʻole Non-corrosive:
Ke inert kemika nā mea ʻāpana silikone a loaʻa iā lākou ka punahelu maikaʻi e hoʻokuʻu ana i ka waiwai. E like me ka mea ʻaʻole lākou e corrode i nā mea ʻē aʻe. Ma muli o kēia waiwai, hoʻohana ʻia lākou e like me nā ʻōwili paʻa o nā mīkini paʻi paʻi, nā ʻōwili paʻi, nā lau a pēlā aku.
Manaʻo ʻia he pololei ka ʻike ma luna aʻe akā ʻaʻole kuhi ʻia e hoʻopili āpau ʻia. E like me ka hoʻololi ʻana o nā kūlana hana o kēlā me kēia mea i ka palapala noi o kēlā me kēia huahana, hiki ke ʻike ʻia ka ʻike ma kēia pepa ʻikepili ma ke ʻano he alakaʻi. ʻO ia wale nō ke kuleana o ka mea kūʻai aku e loiloi i kāna mau koi ponoʻī, ʻoiai inā lawa nā waiwai i kuhikuhi ʻia o kā mākou huahana no kāna hoʻohana i manaʻo ʻia.
