What are the characteristics of the production process of aluminum silicate silk carpet? Aluminum silicate spinning blanket (also known as ceramic fiber spinning blanket) is a flexible refractory insulation material made from high-purity aluminum silicate by spinning method (also known as centrifugal spinning method). Pour the molten high-purity aluminosilicate solution (mainly composed of alumina and silica) into a high-speed rotating spinning reel or roller. Characteristics of the production process of aluminum silicate silk carpet:
1. Excellent fiber quality
High toughness and low slag ball content: Long fibers entangle more firmly during subsequent cotton laying and needle punching processes, endowing the blanket with excellent tensile strength and mechanical vibration resistance. At the same time, the process of spinning produces fewer non fibrous slag balls (non fiber impurities), and the slag ball content (>0.25mm) can usually be controlled below 5%, improving the purity and insulation efficiency of the product. 2. Stable product structure
Long fibers interweave with each other, and after needle punching, a more stable three-dimensional network structure is formed in the blanket body. This makes the spinning blanket have lower thermal shrinkage rate and higher high-temperature stability, making it less prone to deformation and pulverization under long-term high-temperature use. 3. Excellent thermal insulation performance
The uniform distribution of fiber diameter can form a more uniform and fine pore structure, effectively suppressing air convection and thermal radiation. Therefore, under the same bulk density and thickness, the thermal conductivity of the spun silk blanket is usually lower than that of the blown blanket, resulting in better insulation effect. 4. Good construction performance
Due to its long fiber length and high strength, the spinning blanket is less prone to breakage and falling off during cutting, folding, wrapping, and installation processes, making construction more convenient, reducing installation losses, and having less skin irritation to workers. 5. High requirements for production process control
The spinning process requires extremely precise control of parameters such as melt viscosity, temperature, and spinning disc speed to ensure stable and consistent fiber quality. This makes the investment and technological threshold for production lines relatively high. 6. Widely applicable
Thanks to its excellent comprehensive performance, the spun aluminum silicate fiber blanket is particularly suitable for fields that require higher strength, stability, and lifespan of refractory insulation materials.
What are the characteristics of the production process of aluminum silicate silk carpet? The core feature of the production process of aluminum silicate spinning blanket lies in "spinning long fibers by centrifugal force". This fundamental difference endows it with a series of outstanding properties such as fiber length, high strength, less slag balls, stable structure, excellent insulation, and long service life. Although the production cost is relatively high, its long-term reliability, energy-saving effect, and reduced maintenance costs in harsh industrial high-temperature environments make it the preferred material for high-end fire-resistant insulation applications.
