Good Thermal Shock Resistance Insulation Brick nsulating Refractory Mullite Bricks For High Temperature Kiln
Good Thermal Shock Resistance Insulation Brick nsulating Refractory Mullite Bricks For High Temperature Kiln also known as mullite lightweight insulating firebrick of high purity refractory powder, according to product requirements proportion, adding organic composite filler, the vacuum extrusion molding, high temperature sintering refractory insulation mullite insulating brick .In the main phase of mullite alumina, alumina content in general 65% ~ 75%.A high degree of fire resistance, up to 1790 degrees celsius. Load softening temperature 1600 ~ 1700 degrees to start. Room temperature compressive strength of 70 ~ 260MPa. Good thermal shock resistance. The sintered mullite and fused mullite brick two .
Laurel produces a comprehensive range of Good Thermal Shock Resistance Insulation Brick nsulating Refractory Mullite Bricks For High Temperature Kiln consisting of 30-55% Alumina all of which exhibit excellent strength. For more arduous environments we offer a hand fired "super duty" Fire clay brick with a very high mechanical strength.
Typically our Good Thermal Shock Resistance Insulation Brick nsulating Refractory Mullite Bricks For High Temperature Kiln range is based upon flint clay giving it both a low iron and low alkali characteristic. Resistance to thermal shock, abrasion, chemical attack and reducing atmospheres are just some of the key criteria determining choice of product within each application. a wide range of sizes are held in stock.
