Comprehensive protection of the metal jet from oxidation
23.05.2017
Mats (blankets, rolls, strips, felt, felt) made of ceramic fibers are new heat-insulating fire-resistant materials, have the exact size, do not contain any fasteners, the color is white.
Ceramic fiber mats (aluminosilicate fiber) are chemically resistant to erosion, hydrofluoric acid, phosphoric acid, concentrated alkalis (sodium and potassium), etc. The properties of mats made of ceramic fibers are not affected by oil and water, after firing, their physical and chemical properties are preserved.
Needle-punched blanket made of ceramic fiber is produced by a rotary method, it has good workability, quick and easy installation, excellent thermal insulation properties, can meet the requirements of various furnaces for insulation on hot and cold surfaces.
