ʻO ka puna silicone foam kekahi o nā mea hoʻopaʻa paʻa, damping a me nā mea insulation thermal i kēia wā HVAC, nā mea hana ʻenehana, nā hana uila a me nā ʻoihana ikehu hou. Wahi a nā kaʻina hana hoʻopihapiha hoʻopihapiha, hoʻokaʻawale ʻia i ʻelua mau ʻāpana kumu: fumed foam silicone a precipitated foam silicone. ʻOiai nā mea ʻelua i loko o nā mea silicone foam a kaʻana like i nā ʻano waiwai silicone kumu, ʻo nā ʻokoʻa koʻikoʻi o ka hana hana waiwai e hoʻoholo ai i kā lākou mau āpau i nā waiwai kino, ka lōʻihi, ka hana kūlohelohe a me nā hiʻohiʻona noi. Hoʻokaʻawale ʻia kēia ʻatikala i nā mea like a me nā ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua, e hāʻawi ana i ke kumu koho ʻoihana loea no nā mea hoʻolālā ʻenehana, nā mea hana mea hana a me nā mea kūʻai ʻenehana.
1. Nā mea like ma waena o Fumed a me Precipitated Foam Silicone
ʻO ka mea nui, ʻo ka silikoni fumed foam a me precipitated foam silicone he mau mea elastic porous sponge i hana ʻia ma o ka hui ʻana i nā mea kumu kumu lāʻau silikoni, hoʻohui i nā mea hoʻohāhā a me nā mea hoʻohui kōkua, a ke komo nei i ka -welikino wela kiʻekiʻe a me ka hoʻohuhū ʻana. Loaʻa iā lākou nā pōmaikaʻi koʻikoʻi o nā mea silicone organik a loaʻa iā lākou nā hiʻohiʻona noi maʻamau i nā hiʻohiʻona ʻoihana. ʻO ka mea mua, loaʻa nā mea ʻelua i ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, e mālama mau ana i ka hana elastic ma ka laulā wela maʻamau o -50 degere a 200 degere, a ʻaʻole e paʻakikī, māwae a deform paha ma lalo o ka mahana maʻamau alternating kūlana hana. ʻO ka lua, loaʻa iā lāua ʻelua ka maʻalahi, ka ʻili o ka ʻili a me ka hana haʻalulu haʻalulu, hiki ke hoʻopiha pono i nā ʻāpana hui o nā lako, a pāʻani i nā kuleana o ka hoʻopaʻa ʻana i ka ea, ka pale ʻana i ka lepo, ka hoʻohaʻahaʻa haʻalulu a me ka hoʻohaʻahaʻa leo. ʻO ke kolu, hoʻohana lāua ʻelua i nā hale kūʻokoʻa paʻa -cell a i ʻole semi-pani -cell foam, me kekahi mau mana wai a me ka makū, a hiki ke pale aku i ke komo ʻana o ka mahu wai a me ka hōʻiliʻili ʻana o ka wai i loko o nā kaiapuni maʻamau a me nā mea hoʻopaʻa. Eia kekahi, kākoʻo nā mea ʻelua i nā ʻano hana hohonu e like me ka extrusion molding, die cutting a me back adhesive lamination, a hiki ke hoʻopili ʻia i loko o nā kikoʻī like ʻole o nā strips, gaskets a me nā ʻāpana e hoʻokō i nā pono hoʻohālikelike like ʻole o nā lako mīkini a me nā hoʻonohonoho ʻenekinia.
2. Nā ʻokoʻa koʻikoʻi ma waena o Fumed a me Precipitated Foam Silicone
ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua mai ka silica hoʻopiha piha ʻana a me ka silica precipitated, i hoʻomākaukau ʻia e nā kaʻina hana ʻokoʻa like ʻole, e alakaʻi ana i ka ʻokoʻa ʻokoʻa o ka microstructure material, nā waiwai mechanical, ka pale ʻana i ka wā kahiko a me nā paepae noi, a me ka hoʻokumu ʻana i ke kūlana kiʻekiʻe a me ka gradient maʻamau i ka mākeke ʻoihana.
E pili ana i ka hana hana a me ka microstructure, hoʻohana ʻia ka silicone fumed foam silicone kiʻekiʻe -maemaʻe nano fumed silica i hoʻohui ʻia e ka -kiʻekiʻe mahanahana kinoea-pā ahi. ʻO nā ʻāpana hoʻopiha piha he -maikaʻi loa, ʻano like ka nui a kiʻekiʻe i ka maʻemaʻe, hiki ke hana i kahi ʻano hoʻohui keʻa paʻa-me nā molekala kopa silicone. Ma hope o ka huʻa ʻana, liʻiliʻi nā pores o loko, ʻaʻahu a paʻa, ʻaʻohe pores nui a i ʻole pore defects. ʻO ka ʻokoʻa, hoʻohana ʻia ka silica precipitated foam i hoʻomākaukau ʻia e ka hoʻoheheʻe kemika. ʻOi aku ka maʻemaʻe o nā ʻāpana hoʻopihapiha, me ka hāʻawi ʻole ʻana i ka nui o nā ʻāpana a me nā koena haumia. ʻO ka mea i hoʻoulu ʻia he ʻano pores o loko, ka nui ʻole o ka pore a me nā hale ʻokoʻa kūloko, e hopena i ka hoʻopaʻa ʻana o nā mea āpau.
Ma ke ʻano o ka hana mechanical a me ka lōʻihi, ʻo fumed foam silicone he kūʻē tensile koʻikoʻi, kū i ka waimaka a me ka hana hoʻihoʻi elastic. ʻOi aku ka kiʻekiʻe o kona elongation ma ka haʻihaʻi ma mua o nā mea i hoʻoheheʻe ʻia, ʻaʻole ia e lilo i keʻokeʻo a i ʻole māwae ma hope o ke kulou mau ʻana a me ka extrusion. ʻO ka mea nui loa, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke mālama i ka elasticity sealing paʻa no ka manawa lōʻihi ma lalo o ka hoʻomau mau ʻana a me nā kūlana hana vibration, e pale aku i ka leakage ea a me ka hemahema i hoʻokumu ʻia e ka elastic attenuation. Loaʻa i ka silicone foam precipitated ka ikaika mechanical maʻamau; He mea maʻalahi ia i ke keʻokeʻo i ka wā e hoʻolōʻihi ʻia a maʻalahi e haehae ma lalo o ka ikaika o waho. Ma hope o ka lōʻihi -koomi ʻana, wikiwiki ka elastic attenuation, kiʻekiʻe ka nui o ka deformation mau loa, a maʻalahi ka ʻike ʻana o ke āwaha hoʻopaʻa ma hope o ka luhi ʻana o ka mea, e hōʻemi ana i ka hana sila ʻana o ka lako.
E pili ana i ka pale kaiapuni, ka pale ʻana i ka wā kahiko a me ka hana palekana, hana ʻia ka silicone fumed foam me ka -maʻemaʻe kiʻekiʻe, me ka haʻahaʻa haʻahaʻa, ʻaʻohe sulfur a ʻaʻohe ʻala ʻokoʻa. Hiki iā ia ke hoʻokō i nā kūlana palekana kūlohelohe a me ka hoʻomaʻemaʻe e like me REACH a me FDA, a hiki ke hoʻokō i ka UL94 V0 kiʻekiʻe o ka lapalapa ahi. He kūpaʻa ikaika kona i ka ʻelemakule wela, ultraviolet a me ka hoʻoheheʻe ʻia ʻana o ke kaiapuni, a hiki ke mālama i nā waiwai kino paʻa no 5-8 makahiki i ka -kiʻekiʻe-makahiki lōʻihi a me nā kaiapuni hana anu a me ka wela. Loaʻa i ka silicone foam precipitated trace volatile precipitates, kekahi pilau i loko o ke kaʻina hana, a ʻaʻole hiki ke hoʻokō i ka hoʻomaʻemaʻe a me ka ʻai{11}}mau kūlana palekana kaiapuni. ʻO ka nui o ka HB ka papa hoʻopaʻa ahi, me ka haʻahaʻa kiʻekiʻe kiʻekiʻe-e kūʻē i ka wā kahiko. Hiki i ka melemele, ka pa'akikī a me ka pohā ma hope o ka -mau hana wela ki'eki'e, a he 2-3 makahiki wale nō ke ola o ka lawelawe.
E pili ana i nā hi'ohi'ona noi a me ka ho'onohonoho 'ana i ke kumu kū'ai, 'o ka fumed foam silicone kahi mea ho'opa'a 'oihana ki'eki'e, i ho'ohana nui 'ia i nā hi'ohi'ona ki'eki'e e like me nā ʻōnaehana HVAC kikowaena ea, nā lako lako ea ho'oma'ema'e lapa'au, nā lako uila pololei, nā lako pahu pahu ikehu hou a me nā ke'ena ka'a ka'a. He kūpono ia no nā kūlana hana e koi ana i ka paʻa paʻa o ka ea no ka manawa lōʻihi, ʻaʻohe ʻala ʻokoʻa, hoʻopaneʻe ahi nui a me ka wehe pinepine ʻana a me ka pani ʻana o nā mea hana. ʻO ka silicone foam precipitated he kumu kūʻai-maʻamau maʻamau, hoʻohana nui ʻia i nā hiʻohiʻona kivila-haʻahaʻa-e like me nā ea ea hale, nā ʻōnaehana ea maʻamau, nā mea hoʻoheheʻe makani liʻiliʻi a me ka hoʻopiha piha ʻana i ka lepo mechanical. He kūpono ia no nā kūlana hana maʻamau me nā koi kaiapuni haʻahaʻa, ʻaʻohe hana hoʻomau -manawa lōʻihi a me nā pōʻai maʻamau.
3. Hōʻuluʻulu manaʻo a me nā mea koho
ʻO ka hōʻuluʻulu ʻana, ʻo ka silicone fumed foam a me ka silicone foam precipitated i kūlike i nā ʻano mea silicone kumu a me ka hoʻoponopono ʻana i ka hoʻoponopono ʻana, akā hana i kahi gradient hana maʻalahi ma muli o nā kaʻina hana hoʻopihapiha. Hoʻopili ʻia ka silicone foam precipitated i ka hana kumu kūʻai a hoʻokō i nā pono hoʻopaʻa a me ka hoʻoheheʻe ʻana o nā mea hana kīwila a me ka haʻahaʻa, ʻo ia ka mea makemake no nā papahana maʻamau i hoʻomalu ʻia. Ke hilinaʻi nei ka silicone fumed foam i kona ʻano paʻa, elasticity paʻa, kūpaʻa ʻelemakule maikaʻi a me ka palekana o ke kaiapuni kiʻekiʻe, a ʻo ia ka mea hoʻohālikelike maʻamau no ke kiʻekiʻe -hopena -ola a kiʻekiʻe-ke kākoʻo ʻoihana maʻamau a me ka hoʻopaʻa paʻa pono ʻana. Ma ke koho ʻana i nā mea maoli, pono ia e hoʻoponopono piha e like me ka ʻenehana hana ʻana, nā kūlana palekana, nā koi ola lawelawe a me ka waihona kālā o ka papahana e koho i ka mea hoʻopaʻa silicone foam kūpono loa.
