ʻO ka ʻokoʻa ma waena o ka silica gel thermal a me ka momona wela

1. He aha nā ʻano o ka silica gel wela (thermal potting glue)?

Ua kapa ʻia ʻo silicone conductive thermally thermally conductive potting glue a i ʻole thermally conductive RTV glue.He haʻahaʻa-viscosity flame-retardant ʻelua mea hoʻohui ʻano silicone heat-conducting potting glue.Hiki ke ho'ōla ma ka lumi wela a wela paha.ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka wikiwiki o ka hoʻōla.kūikawā.ʻO ka ʻokoʻa nui loa mai ka ʻaila silicone thermal ka hiki ke hoʻōla ʻia ka silicone thermal a loaʻa kekahi mau waiwai adhesive.

Thermally conductive silica gel (thermally conductive potting glue) ʻo ia ke ʻano o ka ʻili silikoni, nona ka ʻōpala wai o ka vulcanization wela o ka lumi hoʻokahi.I ka manawa e ʻike ʻia ai i ka lewa, hoʻohui ʻia nā monomers silane i loko e hana i kahi hoʻonohonoho pūnaewele, ua hoʻopili ʻia ka ʻōnaehana, ʻaʻole hiki ke hoʻoheheʻe ʻia a hoʻoheheʻe ʻia, he elastic, lilo i rubbery, a pili i nā mea i ka manawa like.ʻOi aku ka kiʻekiʻe o kona conductivity thermal ma mua o ka ʻōpala maʻamau, akā ʻoi aku ka haʻahaʻa ma mua o ka momona silicone conductive thermal, a i ka manawa i ho'ōla ʻia, paʻakikī ke hoʻokaʻawale i nā mea i hoʻopaʻa ʻia.

2. He aha nā ʻano o ka momona wela
ʻO ka momona silicone thermally conductive i kapa ʻia ʻo "thermally conductive paste", "silicon paste", thermally conductive silicone grease he ʻano mea kiʻekiʻe thermal conductivity insulating silicone material, ʻaʻole ia e ho'ōla, a hiki ke mālama i ke kūlana o ka momona no ka manawa lōʻihi. i ka mahana o -50°C-+230°C thermally conductive mea.ʻAʻole wale ka maikaʻi o ka uila insulation, akā loaʻa nō hoʻi i ka conductivity thermal maikaʻi loa, a i ka manawa like he haʻahaʻa haʻahaʻa o ka ʻaila (e like me ka zero), kiʻekiʻe a me ka haʻahaʻa haʻahaʻa pale, ka wai kū, ka ozone kū'ē, a me ka wā kahiko kū'ē.

Hiki ke hoʻohana nui ʻia i nā huahana uila like ʻole, a me ka ʻili pili ma waena o nā mea hoʻomehana (nā paipu mana, nā mea hoʻoponopono silicon, nā pahu hoʻomehana uila, a me nā mea ʻē aʻe). , hoʻohāhā a me nā waiwai ʻē aʻe.

He kūpono ia no ka uhi ʻana i ka ʻili a i ʻole ka ipuhao holoʻokoʻa o nā ʻenehana microwave like ʻole e like me ke kamaʻilio microwave, nā lako hoʻoili microwave, ka lako mana kūikawā microwave, a me ka lako mana hoʻopaʻa ʻia.Hāʻawi kēia ʻano mea silika i ka conductivity thermal maikaʻi loa no nā mea uila e hoʻohua ai ka wela.E like me: transistors, CPU hui, thermistors, nā ʻike wela, nā ʻāpana uila automotive, nā pahu hau kaʻa, nā modula mana, nā poʻo paʻi, etc.

3. ʻO nā mea like a me nā ʻokoʻa ma waena o ka silica gel wela a me ka momona wela
He aha kā lākou mea maʻamau: loaʻa iā lākou a pau ka thermal conductivity a me ka insulation, a ʻo lākou nā mea pili wela.

ka ʻokoʻa:

ʻO ke silikoni hoʻoheheʻe wela (hoʻoheheʻe ʻia i ka ipu hao): pipili (hoʻokahi paʻa, paʻakikī ke wehe,

No laila, hoʻohana nui ʻia i nā manawa kahi e pono ai ka hoʻopaʻa ʻana i hoʻokahi manawa.He translucent, hoʻoheheʻe i ka wela kiʻekiʻe (wai viscous), paʻa (hōʻike) i ka wela haʻahaʻa, ʻaʻole hiki ke hoʻoheheʻe a hoʻoheheʻe ʻia, a he elastic.

ʻO ka momona silikoni thermally conductive (thermally conductive paste): Adsorptive, non-sticky, paste semi-liquid, non-volatile, non-curing (ʻaʻole mānoanoa i ka wela haʻahaʻa, a ʻaʻole ʻoi aku ka lahilahi i ka wela kiʻekiʻe).

4. Laulā noi

Ke hoʻohālikelike ʻia me ka silica gel, ʻoi aku ka nui o ka hoʻohana ʻana i ka momona silicone.Nui nā huahana ʻenehana a me nā mea uila e hoʻohana i ka ʻaila silicone conductive thermal kahi e koi ʻia ai ka wela.

Eia kekahi, nui nā ʻano o ka ʻaila silicone, a hoʻohui ka poʻe i kekahi mau "mea haumia" i ka momona silicone conductive thermal maʻemaʻe e hoʻomaikaʻi i kona conductivity thermal.

ʻO kēia mau mea haumia ʻo ka pauka graphite, ka pauka alumini, ka pauka keleawe a pēlā aku.

ʻO ka momona silicone maʻemaʻe he keʻokeʻo waiū keʻokeʻo, ʻo ka momona silicone i hui pū ʻia me ka graphite he ʻeleʻele i ka waihoʻoluʻu, ʻo ka ʻaila silicone i hui pū ʻia me ka pauka alumini he hina a ʻālohilohi, a ʻo ka momona silicone i hui pū ʻia me ka pauda keleawe he melemele.
