What is Ceramic millboard
Ceramic millboard is a high temperature insulation board. It is characteristic of excellent insulation efficiency and good strength for various high temperature applications.
Ceramic millboard is made from refractory ceramic fiber, attending inorganic and suitable organic binders. The mixture is vacuum processed into boards or formed shapes that keep good mechanical strength after heating. The classification temperature of millboard is 1500℃. The board can be used for internal lining of furnace with high strength and anti airspeed eroding.
It has features such as good heat and fire resistance and good high temperature strength. It has excellent thermal stability and can be used at temperatures up to 500℃ and even higher temperature when properly supported. Additionally, it can be used acceptably at extreme temperature up to approximately 1400℃. It is also known for its features such as withstanding vibratory and impact loads easily. It has excellent chemistry quality, low thermal conductivity, low thermal capacity and good insulation.
There could be smoke generated when the binder in the fiber board is burnt above approximately 260℃ but the smoke will disappear soon and once for all. To limit or avoid such smoke generation in initial start-up performance, heat rise should be controlled at about 7℃ per minute to allow the binder to dissipate with moderate temperature increase. The ignition loss of binder in the first startup operation will not adversely affect the insulation value. It can be used at different service temperatures up to a maximum of 1038℃ on the hot surface of the enclosed panel. This board is not to be subjected to direct touch with flame as a hot face refractory material.
Ceramic millboard is ideal for refractory backup insulation behind insulating firebrick and other refractory linings. It is widely used in boiler and furnaces, catering equipment and steel, ferrous, non-ferrous plants.
