Aluminum silicate blanket/felt/roll
Item No.: GQ-ASF
Introduction
Aluminum silicate, also known as ceramic fiber, is a mixture of aluminum, silica, and oxygen that can be either a mineral, or combined with water to form a clay.
Production Technique
The common aluminum silicate blanket is manufactured with flint clay as main ingredient through melting, fiberizing (with addition of an adequate amount of cementing agent), solidification in solidification chamber and cutting. The whole process is fully PLC controlled and the product is formed in one continuous process.
Main Specifications
Density (kg/m3): 90-110
Thickness (mm): 15-50
Width (mm): 400, 600, 1200
