--Application
v It is mostly applied heat preservation of pipeline transportation equipments of the gas and the liquid in electric power, meta llurgy, engineering, chemical industry, petroleum industries etc. Also, it is used to the thermal protective coating of high temperature equipment within electric furnace, heating furnace, steel furnace, annealing furnace, and glass furnace etc.
v For aluminium electrolytic pot, the diatomite insulating brick can be used for the masonry of pot bottom and lower portion of pot side wall along the length as heat insulating layer;
vFor bake oven, the diatomite insulating brick can be used for masonry of wall as heat insulating layer.
