Calcium silicate (microporous calcium silicate) insulation material i hana ʻia me ka silicon dioxide pauka mea (quartz sand powder, diatomaceous earth, etc.), calcium oxide (pono no ke aniani fiber weft, etc.) e like me ka mea nui maka, a laila hoʻohui. wai , Auxiliaries, molding, autoclave hardening, maloʻo a me nā kaʻina hana ʻē aʻe.ʻO nā mea nui o ka calcium silicate he honua diatomaceous a me ka lime mai Shen.Ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, hiki mai ka hopena hydrothermal, he ʻokoʻa ia mai nā mea maka i hoʻohana ʻia e like me nā fibers i hoʻoikaika ʻia a me nā mea kōkua coagulation, ka ratio a i ʻole nā kūlana kaʻina hana, a me nā huahana hopena. ʻokoʻa.
ʻO ka calcium silicate i hoʻohana ʻia i nā mea insulation he ʻelua mau hale aniani.Ua hana mua ʻia ka calcium silicate e Owence Coming Glass Fiber Corporation ma ʻAmelika Hui Pū ʻIa ma kahi o 1940.ʻO ka hoʻāʻo, ka inoa huahana ʻo kaylo (kaylo), hoʻohana ʻia i ka ʻenehana a me ka insulation hale.Mai ia manawa, ua hana pū ka United Kingdom, Iapana, a me ka Soviet Union i ka noiʻi a me ka hana ʻana.Ma waena o lākou, ua ulu wikiwiki ʻo Iapana, a ua hāʻule ka nui o ka huahana mai 350kg/m3 a i 220kg/m3.No nā huahana tobel mullite-type nona ka mahana lawelawe ma lalo o 650 ℃, ua hana ʻo Iapana i nā huahana ultra-māmā me ka nui o 100-130kg/m3.I nā huahana insulation thermal i hoʻohana ʻia i ka ʻoihana insulation thermal ma Iapana, ʻoi aku ka nui o ka calcium silicate ma kahi o 70%.Ua hana ʻo ʻAmelika Hui Pū ʻIa i ka calcium silicate ikaika me ka ikaika flexural> 8MPa, i hoʻohana ʻia ma ke ʻano he gasket no ka hoʻokuʻu ʻana i ka pipeline.
I ka makahiki 1970, ua hana a hoʻohana koʻu ʻāina i ka tobermorite-type calcium acid thermal insulation huahana ma lalo o 650 ° C, a hoʻohana i ka asbestos ma ke ʻano he fiber reinforcing, i hoʻoheheʻe ʻia e ka hoʻolei ʻana, me ka nui o 500-1000kg/m.30 Ma hope o nā makahiki 1980, ua hana hou ʻia.ʻO ke kaʻina hana he kaʻina hana hoʻoheheʻe ʻia, e hoʻomaikaʻi ana i ka maikaʻi o loko a me ka maikaʻi o ka hiʻohiʻona o ka huahana a hoʻemi i ka density i lalo o 250kg/m3.Hoʻomaka i ka hana ʻana i nā huahana non-asbestos calcium silicate thermal insulation i 1 makahiki, a hoʻomaka e hoʻokuʻu aku i kahi hapa o ia mea.
Ua hoʻohana ʻia ka mea insulation calcium silicate mai ka makahiki 1970 a hiki i kēia manawa.Ma ke ʻano o ka hoʻoheheʻe ʻana, ua hoʻololi ʻia mai ka hoʻolei ʻana i ka hoʻoheheʻe ʻana;ma ke ʻano o ka mea, ua hoʻomohala ʻia mai ka asbestos calcium silicate i ka asbestos-free calcium silicate;ma ke ʻano o ka hana, ua hoʻomohala ʻia mai ka waikawa silicic maʻamau.Ua hoʻomohala ʻia ka calcium i ka silicate calcium ultra-light a me ka silicate calcium ikaika kiʻekiʻe.I kēia manawa, he mea hoʻokaʻawale wela kūpono i waena o nā mea paʻakikī.
Ma hope o ka noiʻi ʻepekema, ua hoʻomohala maikaʻi ʻia ka mea hoʻonaninani kūʻokoʻa wela kūikawā a me nā mea hoʻopili wela kiʻekiʻe no ka calcium silicate thermal insulation huahana, a ua hoʻohana nui ʻia lākou, e hoʻonā i ka pilikia ʻaʻole hiki ke hamo ʻia nā huahana calcium silicate me nā mea ʻili maʻamau.
Nā hiʻohiʻona o ka calcium silicate insulation material
He māmā a maʻalahi nā huahana, corrosion ikaika, haʻahaʻa haʻahaʻa thermal conductivity, kiʻekiʻe lawelawe wela a me ka maikaʻi paʻa.
ʻO ke kani ʻana, ʻaʻole hiki ke puhi ʻia, pale i ke ahi, ʻaʻohe ʻino, ʻaʻole e hoʻokuʻu i nā kinoea ʻawaʻawa ke hoʻohana ʻia i nā wela kiʻekiʻe.
Loaʻa iā ia ke kūpaʻa wela a me ke kūpaʻa wela, a paʻa.
ʻO ke kūpaʻa wai maikaʻi, ʻaʻole e hōʻino ʻia ka wai lōʻihi.
He nani ke ʻano o ka huahana, a hiki ke ʻeli ʻia, hoʻolālā ʻia, wili, wili, pena ʻia, a hoʻokomo ʻia.Hoʻopakele hana a maʻalahi.
ʻO ka ʻike ma luna aʻe e pili ana i nā mea insulation calcium silicate i hoʻolauna ʻia e Fiber Cement Board Company.
