ʻO nā silikoni kahi papa polymers i hele mai i nā ʻano like ʻole, e hāʻawi ana i ka mana nui no ka hana maʻamau e hoʻokō i nā pono kūpono o nā ʻoihana olakino a me ka aerospace.ʻO kā lākou mau hiʻohiʻona e hiki ai iā lākou ke hana i nā hana like ʻole, e like me ke sila, lubricating, a me ka hoʻokō ʻana i nā hana ʻē aʻe.
Hoʻopili ʻia ka versatility o Silicone i kona ʻano kino a me nā ʻano mechanical, kahi e lilo ai ia i mea waiwai i nā ʻoihana like ʻole.E komo kēia ʻatikala i nā waiwai maʻamau ʻelima aka pono o ka siliconea makaikai i kaʻehā mau ʻāpana kumuo na mea silicone.Eia kekahi, e kūkākūkā mākou i nā ʻano hana hana like ʻole a wehewehe i ke kumu e lilo ai ke silicone i koho kūpono no kāu mau pono kikoʻī.
1.Silicones ole react kemika a hōʻike ilihune thermal conductivity.
ʻO ka uhaki ʻana i nā kaulahao silicon-oxygen i loko o nā molekele silikoni e pono ai ka nui o ka ikehu.Ma muli o ke kūpaʻa kiʻekiʻe o nā molekala silicone e hoʻololi, ʻaʻole lawa ka ikaika o ka hapa nui o nā kemika e hoʻoulu i nā hopena kemika.ʻO ka hopena, ʻo ka silicone ka mea maʻamau non-reactive chemically.ʻO nā paʻa paʻa i ka silicone ke kuleana no ka nui o kāna mau hiʻohiʻona maikaʻi.
Hōʻike maʻamau nā Silicones i ka conductivity thermal haʻahaʻa ma muli o kā lākou molecular structure, ka mea e pale ai i ka hoʻolaha ʻana o nā haʻalulu wela ma waena o nā molekala.ʻOiai he mea maikaʻi paha kēia waiwai i kekahi mau noi, e like me ka umu umu, hiki ke lilo i palena i nā pōʻaiapili ʻē aʻe kahi e pono ai ka hoʻololi wela.No ka hoʻoponopono ʻana i kēia pilikia, hiki ke hoʻopili ʻia nā mea hoʻopihapiha thermally conductive i loko o ka silicone formulation e hoʻomaikaʻi i ka hoʻoili wela a hoʻokō i nā koi o ka hoʻohana i manaʻo ʻia.
2.Silicone i haʻahaʻa toxicity
Manaʻo ʻia ʻo Silicone he mea ʻino ʻole no ke olakino kanaka.Ua ʻae ʻia e ka FDA no ka hoʻohana ʻana i ka pilina meaʻai a me ka implantation lōʻihi i loko o ke kino kanaka.Eia nō naʻe, e ʻoluʻolu e hahai i nā kuhikuhi a ka mea hana i ka wā e hoʻohana ai i nā huahana silicone e hōʻoia i ka palekana loa.
ʻO 3.Silicone ka mana nui e hoʻokuke i ka wai
Loaʻa i ka Silicone kahi ʻano kūʻokoʻa i kapa ʻia ʻo hydrophobicity, ʻo ia hoʻi he hiki ke hoʻokuʻu i ka wai.Hoʻopili ʻia kēia i nā pūʻulu methyl i hoʻopili ʻia i ke kaulahao polymer silicon-oxygen, ʻaʻohe polar ma ke ʻano a ʻaʻohe pili i nā mole wai.ʻO ka hopena, ʻaʻole hiki i nā molekele wai ke hoʻolaha a komo i ka ʻili silikoni, a ma ke ʻano, ʻoki lākou a ʻōwili.ʻO kēia waiwai hoʻopaʻa wai kamahaʻo, i hui pū ʻia me ka hiki ʻana o ke silicone e hana i kahi paʻa paʻa paʻa me nā ʻāpana like ʻole, hana maikaʻi loa nā huahana sealing silicone, me nā sila hiki ke hoʻomau i nā makahiki he mau makahiki.
4. Hiki i ka Silicone ke hana ma ke ʻano he insulator a me ke alakaʻi o ka uila.
Hoʻohana maʻamau ʻo Silicone rubber ma ke ʻano he insulator ma muli o ka nele o nā electrons manuahi i loaʻa no ka lawe ʻana i nā uku.He mea maikaʻi loa kēia ʻano maikaʻi no nā hoʻohana like ʻole, ʻoiai i loko o ke kahua lapaʻau kahi mea koʻikoʻi ka insulation.Eia nō naʻe, hiki ke hoʻololi ʻia ke silicone e alakaʻi i ka uila i kekahi ʻano no nā noi e like me nā gaskets a me nā pale static.Hoʻopili kēia hoʻololi i ka hoʻohui ʻana i nā mea hoʻopihapiha e like me ke kalapona, kālā, a i ʻole nā mea conductive ʻē aʻe i loko o ka mea silicone.
5.Silicone ke kū'ē kū'ē i nā mea hoʻoheheʻe organik
Hiki i ka Silicone ke pale i ka ʻike ʻana i ka hapa nui o nā kemika ma muli o kāna ʻano hana ʻole a me ka liʻiliʻi o ka ikehu.Eia nō naʻe, hiki i kekahi mau mea inorganic i koho ʻia, ʻoi aku ka nui o ka sulfuric a me ka waika hydrofluoric, hiki ke hōʻeha i ka silicones.E pili ana i nā pūhui organik i hiki ke hana ma ke ʻano he sol, ʻoi aku ka maikaʻi o ka silicones ma hope o ka hoʻopili lōʻihi ʻana me nā mea like toluene, mineral spirits, gasoline, a me carbon tetrachloride.
Ka pono o ka Silicone
ʻO ka versatility o Silicone e lilo ia i mea waiwai no nā ʻoihana like ʻole, me:
* Kaʻa kaʻa: ʻO ka pale wela kiʻekiʻe o Silicone a me ka lōʻihi e lilo ia i mea kūpono i ka hana kaʻa.
* Aerospace: ʻO nā waiwai insulation maikaʻi loa o Silicone a me ke kūpaʻa ʻana i nā wela wela e lilo ia i mea koʻikoʻi i ka hana mokulele.
* Hoʻopili: Hāʻawi nā mea hoʻoheheʻe Silicone i kahi hopena paʻa a paʻa i ka wai no nā ʻano like ʻole.
* Hana: Hoʻohana ʻia nā mea hoʻopaʻa silicone a me nā mea hoʻopili i ke kūkulu hale no ka hoʻopaʻa ʻana i ka ea a me ka wai.
* Mea Kuke: ʻO nā waiwai pale wela o Silicone he mea maikaʻi loa ia no nā mea kuke, e like me ka moena bakena a me nā spatula.
* Lubricants: Hoʻohana ʻia nā lubricants silicone i nā noi like ʻole, me nā mīkini kaʻa, nā mīkini ʻenehana, a me nā mea pono hale.
* Electronics: ʻO nā waiwai insulation maikaʻi loa o Silicone e lilo ia i mea koʻikoʻi i nā mea uila, e like me nā kamepiula, nā kelepona, a me nā televise.
* Hana ʻana i ka poʻi: ʻO ka maʻalahi o ka Silicone a me ka pololei e lilo ia i mea kūpono no ka hana ʻana i nā mold no nā noi like ʻole, me nā mea lapaʻau a me nā ʻāpana kaʻa.
* ʻO ka lāʻau lapaʻau a me ka ʻoki kino: ʻO ka biocompatibility a me ka versatility o Silicone e lilo ia i mea koʻikoʻi i nā implants lapaʻau, prosthetics, a me nā ʻoki hoʻonaninani.
* Nā mea pāʻani a me nā leʻaleʻa: ʻO ka maʻalahi o ka Silicone a me ka lōʻihi e lilo ia i mea kaulana no ka hana ʻana i nā mea pāʻani, nā pāʻani, a me nā mea leʻaleʻa ʻē aʻe.
ʻO nā ʻano mua o ka Silicone
ʻO nā ʻano kino nui ʻehā a i ʻole nā ʻano huahana silicone i helu ʻia ma lalo nei:
• E ho'ōla a hoʻonohonoho paha kēia mau silicones i ka lumi wela.Hoʻohana pinepine ʻia lākou no ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana.Hoʻomaka ka hoʻōla ʻana o RTV-1 i ka hoʻopili ʻana me ka makū i ka lewa.Hele mai nā silicones RTV-2 ma ke ʻano he ʻelua pūhui ʻokoʻa e pono ai ka mea hoʻohana hope e hoʻohui e hoʻomaka i ka hoʻōla.ʻOi aku ka maʻalahi o ka RTV-2 no nā noi e like me ke kālai ʻana a me ka uhi ʻana.
• Liquid Silicone Rubber (LSR): LSR i loko o kahi ʻōnaehana ʻelua, me ka hui pū ʻana o nā mea ʻelua i ka manawa hoʻohana.Ho'ōla maʻamau ia ma kahi wela kiʻekiʻe, me ka hoʻohana ʻana i ka platinum catalyst.ʻO ke kaʻina hana hoʻoheheʻe i hoʻohana ʻia a me nā hiʻohiʻona huahana hope o LSR hiki ke hoʻololi ʻia i kahi ākea o nā noi.
• Fluorosilicone Rubber (FSR): Loaʻa nā molekala FSR i nā ʻāpana hou o ka iwi kuamoʻo silicon-oxygen me nā wahi hoʻopaʻa ʻē aʻe i noho ʻia e nā pūʻulu molekole ʻē aʻe (nā hui methyl a me fluoroalkyl).Hāʻawi kēia i ka mea i ʻoi aku ka maikaʻi o ka pale ʻana i ka aila a me nā wahie.Ua kaulana ʻo FSR no ka hoʻopaʻa ʻana i nā noi i nā hoʻonohonoho mokulele.
• High-Consistency Rubber (HCR): HCR, i ʻike ʻia ʻo “heat-curing rubber,” he mau kaulahao polymer silicone kiʻekiʻe loa.Hiki i ka mea maka ke hoʻokomo i nā mea hoʻopihapiha a me nā mea hoʻohui e loaʻa ai nā hiʻohiʻona makemake.Hoʻolako pinepine ʻia i loko o kahi ʻano hoʻōla hapa, ʻano ʻano "gummy" i ʻōwili ʻia i loko o kahi pepa mānoanoa.He kūpono ia no ka hoʻohana ʻana i kekahi mau lāʻau lapaʻau, me ka paipu, nā baluna, a me nā pepa.
Hele mai ʻo Silicone i nā ʻano kino like ʻole, mai ka wai a paʻa.Chiki iā ustomer ke hana i nā ʻano silicone like ʻole e like me ke ʻano o ka huahana e kūpono i nā koi o nā huahana hope.
Hōʻuluʻulu manaʻo
Ua nānā ka ʻatikala i nā hiʻohiʻona 5 o ka silicone, hoʻomālamalama i kāna mau mea kemika a me ke kino, a ʻimi i nā ʻano like ʻole e hiki ke lawe i nā noi ʻoihana.
No ka ʻike hou aku e pili ana i ka silicone,e ʻoluʻolu e kelepona mai iā mākou.
