He aha ka fiber ceramic?

Ceramic Fiber, a i ʻole Aluminum Silicate Wool blankets i hana ʻia mai kaolin, a i ʻole alumini silicate hui ʻana me ka hiki ke wela a hiki i 1425°C (2600°F).Hōʻike ʻo Refractory Ceramic Fiber (RCF) i kahi ʻohana o nā fiber vitreous synthetic i hoʻohana maʻamau no ka insulation refractory a me ka pale ahi.ʻO nā huahana RCF he "Amorphous nā mea i hana ʻia e ke kanaka i hana ʻia mai ka hoʻoheheʻe ʻana, puhi a milo paha i ka pālolo kaolin calcined (nā huahana mai Minye me kēia kemika he Normal a i ʻole Standard 1260 o nā huahana RCF) a i ʻole kahi hui o ka alumina (Al2O3) a me ka silica (SiO2) .ʻO nā huahana RCF i hana ʻia mai ka hui ʻana o ka alumina (Al2O3) a me ka silica (SiO2) i kapa ʻia ʻo High Purity (a i ʻole HP) RCF huahana.Hiki ke hoʻohui ʻia nā oxides e like me zirconia a me kēlā hoʻololi kemika, e kapa ʻia ka huahana AZS (Alumina Zirconia Silicate) RCF.ʻO ka maʻamau ʻo RCFs he alumina-silicates maʻemaʻe kiʻekiʻe me 48-54% silica a me 48-54% alumina.ʻO ka hana ʻana o AZS e pili ana i ka zirconia RCFs i loaʻa ka 15-17% zirconia a me 35-36% alumina me kahi ʻano silica e like me nā mea i loko o nā fibers maʻemaʻe kiʻekiʻe.

Ma mua o ka hana ʻana o RCF, ua hoʻohana ka poʻe i ka cement refractory a me nā pōhaku lepo e like me ka uhi ʻana o ka umu ahi a i ʻole nā ​​​​mea insulation.Me ka hoʻomohala ʻana o ka fiber Ceramic, hauʻoli ka poʻe i ka hana maikaʻi loa o ka fiber insulation kiʻekiʻe ma o kāna conductivity thermal haʻahaʻa a ʻoi aku ka maikaʻi o ka haʻalulu wela.Hoʻohana nui ʻia nā huahana Refractory Ceramic Fiber (RCF) i nā noi ʻoihana e hāʻawi i ka ikehu pono, ka hoʻoheheʻe wela kiʻekiʻe.I kēia lā, ʻaʻohe hihia o ka maʻi ʻoihana i hōʻike ʻia i ka RCF i nā makahiki he kanahā o ka hoʻohana ʻana.Ma muli o kekahi mau hoʻokolohua holoholona koʻikoʻi, akā naʻe, ua hoʻokaʻawale ka EU i ka RCF ma ke ʻano he carcinogen ʻano 2 i Dekemaba 1997. ʻO Refractory Ceramic fiber (RCF) me kona wela hana kiʻekiʻe a hiki i 1340C ke koho mua loa no ka uhi ʻana o ka umu wela kiʻekiʻe ma Iron Steel a me CPI. (Chemical & Petrochemical Industries) ʻoiai ʻo ka piʻi ʻana o ka hopohopo olakino o RCF a me PCW e koi ana i nā mea kūʻai aku a me nā mea hana e noiʻi a hana i ka hopena ʻokoʻa i ka wā e hiki mai ana.I nā huaʻōlelo maʻalahi, ke ola mau nei ʻo RCF i ka mākeke a pono paha nā mea kūʻai aku e ʻimi i nā huahana ʻē aʻe ma ʻEulopa.ʻO nā huahana ʻē aʻe i RCF he PCW a i ʻole Low Bio-persistence (a i ʻole e kāhea i nā huahana bio-soluble fiber).E kaʻana like mākou i ka ʻike hou aku e pili ana i nā huahana RCF a me Bio Soluble fiber ma ka leka uila inā makemake ʻoe.

Ua hauʻoli ʻo JIUQIANG i ka inoa kiʻekiʻe ma Kina no kāna mau pale RCF a ua kūʻai aku ʻo ia ma luna o 2600 mea kūʻai aku ma ka honua holoʻokoʻa me kāna mau hale hana 5.He ʻike nui ka hui o JIUQIANG me RCF a me Bio Soluble Products.
