The microscopic shortening and accumulation in appearance are more significant, causing the contact gap between the aluminum silicate fiber blanket units to increase. Although there is a pre compression amount left during the installation, the compensation is limited due to the loss of elasticity of the fibers. Flames will enter from the unit joint, causing damage to the anchor and inner layer fibers, resulting in them falling off.
Therefore, the shortening rate of aluminum silicate fiber blanket is an important condition for measuring the temperature and time of fiber blanket use. The temperature at which the shortening rate is less than 2.4% during heating should be the safe operating temperature of the fiber blanket. So in the application technology, while selecting the temperature for fiber blanket use, it is also necessary to coordinate the heating time, and the optimal value of both should be a reliable parameter in the design.
Aluminum silicate fiber blanket has a bright white color, regular scale, and integrates fire resistance, thermal insulation, and thermal insulation. Does not contain any binders. It can maintain good tensile strength, durability, and fiber structure even when used in a neutral and oxidizing atmosphere for a long time. The temperature resistance is between 950-1400. Aluminum silicate fiber blanket has excellent sound absorption and noise reduction functions; Excellent thermal stability; Excellent chemical stability; Excellent tensile strength; Low thermal conductivity; Low heat capacity.
