The difference between rock wool and ceramic fiber wool

Rock wool and ceramic fiber wool both have the characteristics of high-temperature resistance, and can also be used in single crystal furnaces, metallurgical casting, and petroleum cracking, and can be used as ablation-resistant and high-temperature resistant insulation materials; sound-absorbing materials and insulation materials for buildings and equipment; but there are also some differences between the two.

Rock wool and ceramic fiber wool

Differences in production processes

Ceramic fiber loose wool is made by melting high-purity clay clinker, alumina powder, silica powder, chrome sand, and other raw materials at high temperatures in an industrial electric furnace to form a fluid. Then it is blown by compressed air or spun by a spinning machine into fibers, and then collected by a cotton collector to form ceramic fiber wool. The fiber cotton can be further processed into fiber blankets, boards, paper, cloth, ropes, and other products. Ceramic fiber is a highly efficient thermal insulation material with the characteristics of lightweight, high strength, oxidation resistance, low thermal conductivity, good softness, corrosion resistance, small heat capacity,y, and sound insulation.

Rock wool is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, ฯลฯ, through high-temperature melting and fiberization. The fiber can be processed into various products such as boards, tubes, felts, belts, ฯลฯ, which can be used for insulation, fire prevention, sound absorption, and earthquake resistance, ฯลฯ. in buildings and industrial equipment, pipelines, kilns, ฯลฯ. Rock wool board, rock wool tube, rock wool felt.

High-temperature range difference

Ceramic fiber wool has advantages in long service life and high fiber toughness. Ceramic fiber wool has lower thermal conductivity. In addition, the highest operating temperature of ceramic fiber wool is above 1000 องศา. Commonly used types are 1050 and 1230, while the highest operating temperature of rock wool is about 600 องศา.

Application difference

Ceramic fiber wool can be used for low-temperature insulation at 200 องศา, medium-temperature insulation at 500 องศา, and fireproof insulation at 1000 องศา, while rock wool is generally used for insulation at around 500 degrees and is mostly used in thermal pipes.
