Qhov kev faib tawm yog dab tsi insulating refractory bricks

1. High-temperature rwb thaiv tsev bricks, qhov kev pab kub yog siab tshaj 1500 ℃, thiab yuav siv tau ncaj qha raws li lub hauv ob sab phlu ntawm high-temperature kilns, mas suav nrog lub teeb corundum cib, hollow alumina sphere khoom thiab zirconia hollow sphere khoom.

2. Ordinary thermal rwb thaiv tsev cib, kev siv kub yog qis dua 1000 ℃, feem ntau yog diatomaceous earth bricks, nthuav razor pob zeb cib, nthuav perlite cib, thiab lwm yam, uas feem ntau yog siv los ua cua sov rwb thaiv tsev txheej rau cov khoom siv thermal.

3. Refractory thiab tshav kub rwb thaiv tsev cib, qhov kev pab cuam kub ntawm 1000-1500 ℃, feem ntau suav nrog lub teeb av nplaum refractory cib, lub teeb silica cib, lub teeb siab alumina cib, thiab lwm yam.
