1, ʻaʻole wela ka lole pale wela kiʻekiʻe ma 360 degere Celsius ma lalo o ka wela nui loa, ʻaʻole ʻelemakule;Hiki ke ʻā nā lole pale ahi ma lalo o ke ahi wela kiʻekiʻe.
2, ka lole pale ahi ma hope o ka haʻalele ʻana o ke kumu ahi i ka lapalapa e hiki ke pio iā ia iho;ʻAʻole e pio ka lole pale wela kiʻekiʻe ma hope o ka haʻalele ʻana o ke kumu lapalapa i ka lapalapa.
3, hana ʻia ka lole pale ahi i ka pulupulu, polyester a me nā mea maka;ʻO ka lole pale wela kiʻekiʻe i hanaʻia me ke kiʻekiʻe kiʻekiʻe i laweʻia mai ke aniani fiber.
4, hiki i ka lole pale wela kiʻekiʻe ke pale aku i ka corrosion o nā mea lāʻau lapaʻau a pau, i ka waikawa ikaika a me nā kūlana alkali ʻaʻole i ʻelemakule a me ka deformation;ʻAʻohe hana e like me ka lole pale ahi.
Heat insulation refractory e pili ana i ka porosity kiʻekiʻe,Ka lole hoʻokaʻawalehaʻahaʻa leo haʻahaʻa, haʻahaʻa thermal conductivity o refractory.Heat insulation refractory ua ʻike ʻia hoʻi nā kukui kukui.Loaʻa iā ia nā huahana refractory insulation, nā fiber refractory a me nā huahana fiber refractory.Ka lole hoʻokaʻawale
Heat insulation refractory ua hōʻike ʻia e ka porosity kiʻekiʻe, maʻamau 40% ~ 85%;Haʻahaʻa leo haʻahaʻa, maʻamau ma lalo o 1.5g/cm3;Haʻahaʻa thermal conductivity, maʻamau emi ma mua o 1.0W(m· K).Hoʻohana ʻia ʻo ia e like me ka mea insulation thermal o ka ʻoihana kiln, hiki ke hōʻemi i ka nalowale o ka wela o ka umu, mālama i ka ikehu, a hiki ke hōʻemi i ke kaumaha o nā mea wela.ʻAʻole pono e hoʻohana ʻia i ka hoʻokumu ʻana o ka umu ahi a hoʻopili pololei me ka slag, charge, molten metala a me nā ʻāpana ʻē aʻe.
Heat insulating refractory huahanaKa lole hoʻokaʻawale
Hōʻike nā huahana refractory i nā huahana refractory me ka porosity ʻaʻole i emi iho ma lalo o 45%.Nui nā ʻano o nā huahana refractory thermal insulation.ʻO nā ʻano hoʻohālikelike nui penei:
(1) E like me ka lawelawe ana wela ua maheleia i ka haʻahaʻa wela insulation refractory (lawelawe lawelawe mea 600 ~ 900 ° C), medium wela insulation refractory (lawelawe lawelawe he 900 ~ 1200 ° C) a me ke kiʻekiʻe wela insulation refractory (ʻoi aku ka wela o ka lawelawe. ma mua o 1200°C).
(2) Ma muli o ka nui o ka nui, ua māhele ʻia i nā refractory māmā maʻamau (ka nui o ka 0.4 ~ 1.0g/cm3) a me nā refractory kukui ultra-haʻahaʻa.
(3) E like me ka mea maka ua maheleia i loko o ka pālolo, kiʻekiʻe aluminika, silika a me ka magnesium wela insulation refractory mea.
(4) E like me ke ʻano hana, hoʻokaʻawale ʻia i ke ʻano hoʻohui burnout, ke ʻano o ka foam, ke ʻano kemika a me ke ʻano mea porous a me nā mea hoʻonaninani wela.
(5) e like me ke ʻano o nā huahana ua māhele ʻia i loko o ke ʻano o ka wela insulation refractory huahana a me ka amorphous wela insulation refractory huahana.
ʻOkoʻa nā huahana refractory thermal insulation a me nā huahana refractory dense, ʻo ke ʻano nui ke ʻano o ka burnout hoʻohui ʻana, ke ʻano foam, ke ʻano kemika a me ke ʻano mea porous:
