Description
The product is an inorganic material, with the main crystal phase being hard calcium silicate, and its physical and chemical properties are stable.
The product substrate is synthesized from siliceous and calcareous materials through steam pressure hydrothermal process, uniformly distributed with a large number of micron and nanometer-sized pores, with a porosity of 79~91 %, and excellent thermal insulation performance.
The product is a backing insulation material, determined by its performance, and cannot be used as the working layer of a furnace lining.
The product does not contain asbestos or other toxic and harmful components; it has no biological nutrients, will not rot or mold, and poses no risk of pest or rodent damage.
Product characteristics
Low thermal conductivity, good insulation effect
Low thermal shrinkage rate, dimensionally stable
Low bulk density, low thermal capacity
Stable physical and chemical properties, good durability
Product application
As an excellent insulation backing material, the product can be widely used in thermal equipment in most industrial fields.
Cement industry, suitable for insulation and heat preservation of equipment such as preheaters, decomposition kilns, grate coolers, and tertiary air ducts.
