Hana ʻia ʻo Brick Light Weight Clay Insulation Brick i ke ahi palolo grog e like me ka mea maka a me ka pālolo palolo e like me ka mea hoʻopaʻa paʻa a laila e hoʻohui i ka mea hoʻopau a i ʻole ka huʻihue kūpono ma ke kī ʻana. palolo insulation poloka ike porosity kiʻekiʻe e pili ana i 40 ~ 85% a me ka bulk density haʻahaʻa ma mua o 1.5 g/cm3. Hoʻohana nui ʻia nā pōhaku ahi insulation e like me nā mea insulation i ka kiln ʻoihana e hōʻemi i ka nalowale o ka wela o ka kiln, mālama i ka ikehu a hoʻomāmā i ka maikaʻi o nā mea wela.
Hana ʻia ʻo Brick Light Weight Clay Insulation Brick mai ka lepo ahi maʻemaʻe kiʻekiʻe a me ka mea hoʻopaʻa, ma o ka sintering ma o ka wela kiʻekiʻe. palolo insulation poloka he haʻahaʻa kumu kūʻai refractory insulation brick me ka hana kiʻekiʻe. ʻO nā pōmaikaʻi nui o ka poloka insulation pālolo ka refractoriness kiʻekiʻe ma lalo o ka ukana, nā coefficient hoʻonui laina haʻahaʻa, ke kūpaʻa haʻalulu maikaʻi a me ka ikaika ikaika e pale aku i ka erosion. Hana ʻia i nā mea ahi ahi ma lalo o ka wela kiʻekiʻe e like me ke kūlana aupuni mau loa, nona ka puʻupuʻu nui, ikaika kiʻekiʻe, haʻahaʻa thermal conductivity a me ka haumia haʻahaʻa.
Pālolo insulation firebrick mea argillaceous huahana me kahi 30 ~ 40% Al2O3 maʻiʻo. ka mea i hana ʻia me 50% pālolo palupalu a me 50% chamotte paʻakikī e like me kekahi granularity pono e hui pū ʻia a puhi ʻia ma 1300 ~ 1400 ℃ kiʻekiʻe wela ma hope o ka hoʻoheheʻe ʻana a me ka maloʻo. Pālolo insulation ahi brick main mineral haku mele kaolinite (Al2O3·2SiO2·2H2O) a me 6~7% haumia (K, Na, Ca, Ti, Fe oxide).

Hoʻohana nui ʻia ka poloka insulation pālolo no ka uhi insulating o nā wahi wela a i ʻole ke kākoʻo ʻana i nā papa insulating wela o nā mea refractory ʻē aʻe. ʻO nā linings refractory a i ʻole nā mea wela insulating o nā ʻoihana, e like me, ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high temperature shullte kilns, etc.
