La diferencia entre la lana de roca y la lana de fibra de cerámica

Rock wool and ceramic fiber wool both have the characteristics of high-temperature resistance, y también se puede usar en hornos de cristal único, fundición metalúrgica, y crujido de petróleo, y se puede usar como materiales de aislamiento resistentes a la alta temperatura y resistentes a la ablación; Materiales de absorción de sonido y materiales de aislamiento para edificios y equipos; 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, polvo de sílice, 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, alta resistencia, resistencia a la oxidación, baja conductividad térmica, good softness, resistencia a la corrosión, pequeña capacidad calorífica,Y, and sound insulation.

Rock wool is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc., through high-temperature melting and fiberization. The fiber can be processed into various products such as boards, tubes, felts, belts, etc., which can be used for insulation, fire prevention, sound absorption, and earthquake resistance, etc.. in buildings and industrial equipment, pipelines, horno, etc.. 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. Además, the highest operating temperature of ceramic fiber wool is above 1000 grados. Commonly used types are 1050 y 1230, while the highest operating temperature of rock wool is about 600 grados.

Application difference

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