System of brick of heat preservation of argillaceous qualitative heat insolation is secret

Clay pledges adiabatic firebrick calls argillaceous heat preservation the brick again, with heavy qualitative firebrick disparate, density of bulk of brick of adiabatic heat preservation is lower and heat preservation performance is better. We let know this kind of fireproof product below.
Content of Al2O3 of brick of heat preservation of argillaceous qualitative heat insolation is in more commonly 40 ％ above, fe2O3 content is less than 2 ～ 2.5 ％ . The grog in burden is 65 ～ 85 ％ , combinative clay is 35 ～ 15 ％ . Mix the combines clay and mill grog that smash grind, make up half dry pug together with grain grog again, high pressure shapes, firing below about 1400 ℃ , performance is better. Argillaceous brick shows weak acidity below high temperature.


Clay pledges adiabatic firebrick belongs to adiabatic and fireproof material, it has porosity density of tall, bulk is low, heat conduction leads low good point.
The porosity that sticks earthy and adiabatic firebrick is in commonly 40%-85% ; Bulk density is low under 1.5g/cm3; Thermal conductance is low, general under 1.0W (M.K) .
The over all dimension that sticks earthy and adiabatic firebrick basically is a basis " size of general firebrick shape " ask and make.
Clay pledges adiabatic firebrick manages change target:


Clay pledges brick of adiabatic heat preservation presses bulk density cent to be NG-1.5, NG-1.3a, NG-1.3b, NG-1.0, NG-0.9, NG-0.8, NG-0.7, NG-0.6, NG-0.5 and NG-0.4 10 kinds of brands.
Clay pledges brick of adiabatic heat preservation is the heat-insulating material that industrial kiln furnace recommends, it can reduce furnace kiln heat loss due to radiation, save the sources of energy, can reduce the quality of hot project facilities.


But what we should notice is, sex of caustic of intensity of machinery of brick of heat preservation of argillaceous qualitative heat insolation, wear-resisting and the aggressivity that fight broken bits is poorer. Because this is unfavorable,be used at kiln furnace bearing structure and direct contact the place such as metal of slaggy, charging, melt.
