He aha ka mea hoʻoheheʻe wela?ʻO nā lula maʻamau o nā mea hana a me ka ʻenehana insulation pipeline, thermal insulation material ʻo ia hoʻi ke like ka awelika o ka mahana ma lalo o 623K (350 ° C), ʻoi aku ka liʻiliʻi o ka conductivity thermal ma mua o 0. 14W / (mK) mea.ʻO nā mea insulation maʻamau he māmā, ʻoluʻolu, porous, a me ka haʻahaʻa haʻahaʻa.Hoʻohana maʻamau ia no ka pale ʻana i ka nalo wela i nā mea wela a me nā paipu, a i ʻole i hoʻohana ʻia i ka hau (i kapa ʻia ke anuanu maʻamau) a me ka wela haʻahaʻa (i kapa ʻia ʻo cryogenic), no laila ua kapa ʻia nā mea hoʻonā wela ma koʻu ʻāina i ka mālama wela a i ʻole nā mea mālama anu.I ka manawa like, ma muli o ke ʻano porous a i ʻole ka fibrous o ka mea hoʻonaninani wela me ka hana hoʻoheheʻe kani maikaʻi, hoʻohana nui ʻia ia i ka ʻoihana kūkulu.
Loaʻa i nā mea insulation thermal nā hōʻailona hana.
(1) Ka hoʻoili wela.Ma ke ʻano he mea hoʻokaʻawale wela, pono e liʻiliʻi ka conductivity thermal e like me ka hiki.ʻO ka mea maʻamau, ʻoi aku ka liʻiliʻi o ka conductivity wela ma mua o 0.14W/(mK).Ma ke ʻano he mea hoʻokalakupua wela no ka mālama anuanu, ʻoi aku ka kiʻekiʻe o ke koi no ka conductivity thermal.
(2) ʻO ka nui o ka nui, ke kaumaha o nā mea insulation - ma ke ʻano he haʻahaʻa haʻahaʻa, ʻoi aku ka liʻiliʻi o ka wela, akā i ka manawa like e hoʻemi ʻia ka ikaika o ka mīkini, no laila e koho ʻia kahi koho kūpono. .
(3) Ka ikaika mīkini.I mea e pale aku ai i ka hoʻoheheʻe ʻia ʻana a i ʻole ka pōʻino o ka mea insulation thermal ma lalo o kona kaumaha a me kona ikaika ponoʻī, ʻaʻole e emi iho kona ikaika compressive ma mua o 3kg/cm.
(4) Ka nui o ka lawe ʻana i ka wai.Ma hope o ke komo ʻana o ka wai i ka wai, ʻaʻole ia e hōʻemi nui i ka hana ʻana i ka wela, l He mea ʻino loa ia i ka skimming metala.No laila, pono e koho ke kumu waina i kahi mea wela me ka haʻahaʻa haʻahaʻa o ka wai.
(5) Pono e koho ʻia ka wela wela a me ka hoʻohana ʻana i ka mahana, nā mea hoʻonaninani wela me nā ʻano ʻokoʻa o ka wela e like me ka mahana o kahi e hoʻohana ai.ʻO ka "hoʻohana ʻana i ka mahana" ke kumu no ka pale ʻana i ka wela o nā mea insulation thermal.
ʻO ka ʻike ma luna nei ka ʻike pili e pili ana i ke ʻano o ka insulation wela a me nā mea refractory i hoʻolauna ʻia e kahi ʻoihana papa pale ahi ʻoihana.Mai ka Goldenpower Group ka ʻatikala
