Problems solved by technology

Aluminum silicate ceramic fiber is an emerging thermal insulation material, which has low shrinkage, high temperature oxidation resistance, stable physical and chemical properties, and is harmless to the environment and human body. It also has excellent sound insulation, water resistance, antifreeze, flame retardant and other characteristics, but Its fibers are loose, so its tensile strength and flexural strength are poor, which in turn limits its application
