Ceramic fiber cotton and rock wool both have high temperature resistance characteristics, and there are many similarities between the two. Therefore, some users have asked about the differences between the two. To help everyone understand the differences between the two, let the staff of Henan Ofida Instrument introduce them to you.
Production process
1. Ceramic fiber loose cotton is a material that melts high-purity clay clinker, aluminum oxide powder, silica powder, chrome sand and other raw materials at high temperature in an industrial electric furnace to form a fluid. Then, compressed air is used to spray or a spinning machine is used to spin the yarn into a fibrous shape, which is then collected by a cotton collector to form ceramic fiber cotton. Fiber cotton can be processed into products such as fiber blankets, boards, paper, fabrics, ropes, etc. Ceramic fiber is an insulation material that has the characteristics of light weight, high strength, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, small heat capacity, and sound insulation.
2. Rock wool is an inorganic fiber made mainly from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc., which are melted and fibrotic at high temperatures. After processing, fibers can be made into various products such as boards, pipes, felt, belts, etc. They can be used for insulation, fire prevention, sound absorption, earthquake resistance, etc. in construction and industrial equipment, pipelines, and kilns. Rock wool board, rock wool tube, rock wool felt.
Performance differences
The former has advantages in long service life, high fiber toughness, and lower thermal conductivity. In addition, its high operating temperature is above 1000 degrees, with commonly used 1050 and 1230 types. The latter has a high operating temperature of around 600 degrees.
Application difference
Ceramic fiber cotton can be used for low temperature insulation at 200 degrees, medium temperature insulation at 500 degrees, and fire insulation at 1000 degrees. Rock wool, on the other hand, is commonly used for insulation at around 500 degrees and is often used for insulation in thermal pipelines or power equipment.
