Ceramic fiber blanket, also known as aluminum silicate fiber blanket, has greatly improved the degree of fiber interweaving, anti-delamination performance, tensile strength and surface smoothness after the double-sided needling process, so it is also called aluminum silicate needle-punched blanket. The fiber blanket does not contain any organic binder to ensure that the ceramic fiber blanket has good formability and stability under high temperature and low temperature conditions. The ceramic fiber blanket is white in color and regular in size, integrating fire resistance, heat insulation and heat preservation.
It can still maintain good tensile strength, toughness and fiber structure after long-term use in neutral and oxidizing atmospheres. The temperature resistance is 900-1500°C. It occupies a dominant position in the use of high-temperature pipelines. Ceramic fiber blankets have strong thermal insulation capabilities, so they can save more heat, which is 1.2 times the energy-saving capability of similar thermal insulation materials (such as thermal insulation bricks, etc.), and are gradually replacing asbestos. products. Its advantage is that it does not contain harmful ingredients to the human body.
Classification
Classification of ceramic fiber blankets according to different characteristics
According to the processing technology of ceramic fiber, it can be divided into two types: spinning blanket and blown blanket.
The ceramic fiber used in the silk blanket is thicker and longer than that of the blown blanket, so the tensile and flexural strength of the silk blanket is higher than that of the blown blanket, and it is suitable for thermal insulation environment with higher requirements for bending and tensile properties. The sprayed ceramic fiber is thinner than the silk blanket, so it is inferior to the blanket in terms of flexural and tensile strength, but the thermal conductivity of the blown blanket is better, and it is suitable for ceramic fiber blankets that require low tear resistance, but for insulation Environments with higher thermal performance requirements.
