1. Nānā o ke aniani insulating
,
ʻO ke aniani insulated kahi ʻano o ke aniani mālama i ka ikehu i hoʻohana nui ʻia i nā hale keʻena ʻoihana, nā hale kūʻai kūʻai nui, nā hale noho kiʻekiʻe a me nā hale ʻē aʻe. Loaʻa iā ia ka maikaʻi o ka wela wela a me ke kani ʻana o ke kani a nani a kūpono hoʻi. Hana ʻia ke aniani i hoʻopaʻa ʻia me nā ʻāpana aniani ʻelua (a ʻoi aku paha) i hoʻopaʻa ʻia me nā spacers. ʻElua ʻano nui o ka hoʻopaʻa ʻana: ke ʻano hoʻopaʻa ʻana a me ke ʻano hoʻopaʻa paʻa. I kēia manawa, ʻo ke sila ʻelua i ke ʻano hoʻopaʻa paʻa ka mea maʻamau i hoʻohana ʻia. E like me ka mea i hōʻike ʻia ma ke Kiʻi 1: ʻelua ʻāpana aniani i hoʻokaʻawale ʻia e nā spacers, a ua hoʻohana ʻia ka butyl sealant e sila ai i ka spacer a me ke aniani i mua.E hoʻopiha i ka loko o ka spacer me ka kānana molekala, a e hoʻopaʻa i ke āpau i hana ʻia ma waena o ka lihi o ke aniani a me waho o ka spacer me kahi sealant lua.
,
ʻO ka hana o ka mea hoʻopaʻa mua e pale i ka mahu wai a i ʻole ke kinoea inert mai ke komo ʻana a i waho o ka lua. Hoʻohana pinepine ʻia ka butyl sealant no ka mea he haʻahaʻa loa ka nui o ka hoʻouna ʻana i ka mahu wai a me ka wikiwiki o ka lawe ʻana i ke kinoea inert o ka butyl sealant. Eia nō naʻe, ʻo ka butyl sealant ponoʻī he haʻahaʻa ka ikaika hoʻopaʻa haʻahaʻa a me ka elasticity haʻahaʻa, no laila pono e hoʻopaʻa ʻia ke ʻano holoʻokoʻa me kahi sealant lua e hoʻopaʻa i nā papa aniani a me nā spacers. Ke hoʻokau ʻia ke aniani insulating, hiki i kahi papa o ka sealant ke mālama i kahi hopena sila maikaʻi. I ka manawa like, ʻaʻole pili ka hale holoʻokoʻa.

2. Nā ʻano o nā sealants lua no ke aniani insulating
,
ʻEkolu mau ʻano nui o nā sealants lua no ke aniani insulating: polysulfide, polyurethane a me ke silicone. Hōʻike ka papa 1 i kekahi mau hiʻohiʻona o nā ʻano sealants ʻekolu ma hope o ka hoʻōla piha ʻana.
Papa 1 Hoʻohālikelike i nā hiʻohiʻona hana o ʻekolu ʻano sealants lua no ke aniani insulating
ʻO ka maikaʻi o ka polysulfide sealant ʻo ia ka haʻahaʻa haʻahaʻa o ka wai a me ka argon kinoea transmittance i ka lumi wela; ʻO kona hemahema, ʻo ia ke kiʻekiʻe o ka lawe ʻana i ka wai.
Ua emi nui ka modulus a me ka elastic recovery rate i ka piʻi ʻana o ka mahana, a ʻoi aku ka nui o ka neʻe ʻana o ka mahu wai ke kiʻekiʻe ka wela. Eia kekahi, ma muli o ka maikaʻi ʻole o ka pale ʻana i ka wā kahiko o UV, ʻo ka irradiation UV lōʻihi e hana i ka degumming non-stick.

ʻO ka maikaʻi o ka polyurethane sealant ʻo ia ka haʻahaʻa o kona mahu wai a me ka argon gas transmittance, a ʻoi aku ka haʻahaʻa o ka lawe ʻana o ka wai i ka wā kiʻekiʻe ka wela; ʻO kona hemahema ʻo ia ka maikaʻi ʻole o ka ʻelemakule UV.
,
ʻO ka silicone sealant e pili ana i kahi mea hoʻopaʻa me ka polysiloxane ma ke ʻano he kumu waiwai nui, i kapa ʻia hoʻi ka ʻōnaehana hana mahiʻai silicone sealant. ʻO ke kaulahao polymer o ka silicone sealant ka mea nui o Si-O-Si, kahi i hoʻopili ʻia e hoʻokumu i kahi ʻano hui like ʻo Si-O-Si i ka wā o ka hoʻōla ʻana. He kiʻekiʻe loa ka ikehu paʻa Si—O (444KJ/mol), ʻaʻole ʻoi aku ka nui ma mua o nā ikehu paʻa polymer ʻē aʻe, akā ʻoi aku ka nui ma mua o ka ikehu ultraviolet (399KJ/mol). ʻO ka molecular structure o ka silicone sealant hiki i ka silicone sealant ke loaʻa i ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka pale ʻana i ka wā a me ka pale ʻana o UV, a me ka haʻahaʻa haʻahaʻa o ka wai. ʻO ka hemahema o ka silicone sealant ke hoʻohana ʻia i ke aniani insulating he kiʻekiʻe ke kinoea permeability.
3. Koho pololei o ka sealant lua no ke aniani insulating
,
Inā ʻike ʻia ka ʻili o ka polysulfide glue, polyurethane glue a me ke aniani i ka lā no ka manawa lōʻihi, e hiki mai ana ka degumming, kahi e hāʻule ai ka ʻāpana o waho o ke aniani insulating o ka pā huna aniani a i ʻole ka sila ʻana o ka pā. e hāʻule ke aniani hoʻokaʻawale o ka pā aniani i kākoʻo ʻia.No laila, pono e hoʻohana i ka sealant kiʻekiʻe no ka insulating aniani o nā paia pale pale huna a me nā paia semi-huna ʻia ka hoʻohana ʻana i ka sealant structural silicone, a pono e helu ʻia ka nui o ka interface e like me JGJ102 "Nā kikoʻī kikoʻī no ke aniani pale pale ʻenehana";
Pono e hoʻohana i ka sealant structural silicone ka mea hoʻopaʻa lua no ke aniani insulating o nā paia pale aniani i kākoʻo ʻia; no ka sealant lua o ke aniani insulating no ka nui-nui hamama puka aniani paia, ua paipai 'ia e hoʻohana insulating aniani silicone structural sealant.Hiki ke hoʻopaʻa ʻia ka mea hoʻopaʻa lua no ke aniani i hoʻopaʻa ʻia no nā puka, nā puka makani a me nā pā pale hāmama maʻamau i ke aniani silicone sealant, polysulfide sealant a i ʻole polyurethane sealant.
Ma muli o ka mea i luna, pono nā mea hoʻohana e koho i ka huahana sealant lua kūpono no ke aniani insulating e like me ka noi kikoʻī o ke aniani insulating. Ma ka manaʻo e kūpono ka maikaʻi o ka sealant, ʻoiai ke koho ʻia a hoʻohana pono ʻia, hiki ke hana ʻia ke aniani insulating me kahi ola lawelawe e kū ana i nā koi hoʻohana. Akā inā koho pono ʻole ʻia a hoʻohana ʻia, hiki i ka sealant maikaʻi loa ke hana i ke aniani insulating o ka maikaʻi ʻole.
Ke koho ʻana i ka sealant lua, ʻoi aku hoʻi i ka sealant structural silicone, pono mākou e noʻonoʻo pono e hoʻokō ka sealant silicone i nā koi hana o ke aniani insulating, ka launa pū me ka sealing butyl sealant mua, a me ka hana o ka silicone sealant e hoʻokō i nā koi. o nā kūlana kūpono. I ka manawa like, ʻo ke kūpaʻa maikaʻi o nā huahana silicone sealant, ka kaulana o nā mea hana silicone sealant, a me nā ʻenehana lawelawe ʻenehana o ka mea hana a me nā pae i ke kaʻina holoʻokoʻa o ke kūʻai mua ʻana, kūʻai aku, a ma hope o ke kūʻai ʻana he mau mea nui hoʻi e pono ai nā mea hoʻohana. e noonoo.
,
ʻO ka insulating aniani sealant helu no ka haʻahaʻa haʻahaʻa o ke kumukūʻai hana aniani insulating holoʻokoʻa, akā he hopena nui ia i ka maikaʻi a me ke ola lawelawe o ke aniani insulating. ʻO ka hoʻopili ʻana i ke aniani structural sealant pili pono i nā pilikia palekana o ka pā pale. I kēia manawa, ʻoiai e piʻi nui ana ka hoʻokūkū ma ka mākeke sealant, ʻaʻole kānalua kekahi mau mea hana sealant e mōhai aku i ka hana huahana a me ka maikaʻi i ka wā e hoʻemi ai i nā kumukūʻai i mea e lanakila ai nā mea kūʻai aku ma nā kumu kūʻai haʻahaʻa. Ua ʻike ʻia kahi helu nui o nā huahana sealant aniani insulating haʻahaʻa haʻahaʻa a me ke kumu kūʻai ma ka mākeke. Inā koho ʻole ka mea hoʻohana iā ia, i mea e mālama ai i ke kumukūʻai liʻiliʻi o ka sealant, hiki iā ia ke hoʻopilikia i ka palekana a i ʻole ke alakaʻi ʻana i nā pōʻino maikaʻi, hiki ke lilo i mea nui.
,
Ke koi aku nei ʻo Siway iā ʻoe e koho i ka huahana kūpono a me ka huahana maikaʻi; i ka manawa like, e hōʻike aku mākou iā ʻoe i nā pōʻino like ʻole i hoʻohana ʻia e ka hoʻohana ʻana i ka aniani insulating kiʻekiʻe haʻahaʻa sealant lua a me ka hoʻohana pono ʻole i ka wā e hiki mai ana.
