The difference between rock wool and ceramic fiber wool

Rock wool and ceramic fiber wool both have the characteristics of high-temperature resistance, а также может использоваться в монокристаллических печах, металлургическое литье, 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, кремнеземный порошок, 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, стойкость к окислению, низкая теплопроводность, good softness, устойчивость к коррозии, 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, и т. д., through high-temperature melting and fiberization. The fiber can be processed into various products such as boards, tubes, felts, belts, и т. д., which can be used for insulation, fire prevention, sound absorption, and earthquake resistance, и т. д.. in buildings and industrial equipment, pipelines, kilns, и т. д.. 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. Кроме того, the highest operating temperature of ceramic fiber wool is above 1000 степени. Commonly used types are 1050 и 1230, while the highest operating temperature of rock wool is about 600 степени.

Application difference

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