Types of ceramic fiber cotton
Ceramic fiber wool, also known as aluminum silicate fiber wool or aluminum silicate wool, is a new type of fire-resistant insulation material. The cotton-like one is ceramic fiber loose wool, and the rolled felt-like one is a ceramic fiber blanket. Ceramic fiber wool is classified according to the fire-resistant temperature: there are ordinary type 1050, standard type 1260, high-purity type 1260, high-aluminum type 1400, zirconium-aluminum type 1400, and zirconium-containing type 1400. The long-term working temperature of ceramic fiber wool is 950℃～1280℃. The actual use temperature is -50℃～1280℃.
