Product description:
ZM series lightweight insulation tiles, volume density of 0.5~1.25per cubic centimeter, the use of a temperature of 1250degrees C to 1600 degrees C, each level product formulation of unique design, to meet the needs of users in different environment requirements.
ZM series of lightweight heat insulating brick is made of high quality, high purity raw materials, according to rank with strict classification of filler, forming a uniform pore structure, brick on each side of the machined to the required dimension.
Characteristic:
Low thermal conductivity: have good thermal insulation effect
Low heat capacity: due to low heat rate, ZM series insulating brick accumulation little heat, in intermittent operation and obvious effect of energy saved
Low impurity content: having a very low alkali metal and iron oxide content, therefore high refractoriness, high aluminum content in the reducing atmosphere still maintain good performance.
Hot compressive strength
Dimensions:
accelerate building speed, accurate reduction refractory slurry usage, to ensure the masonry strength and stability, thereby prolonging lining life, can be used as heat surface refractory lining or other refractory insulation backing layer, used in petroleum, chemical industry, ethylene cracking furnace tube type heating furnace, furnace, ammonia synthesis gas furnace, high temperature shuttle kiln and other industrial furnace refractory lining insulation materials.
