In modern high-temperature industrial applications, the choice of insulation material directly affects production safety, energy efficiency, and compliance costs. As a new generation of alkaline earth silicate (AES) ceramic fiber products, CCEWOOL® bio soluble fiber blanket not only inherit the excellent thermal properties of traditional refractory materials but also achieve breakthroughs in biosafety, environmental compliance, and long-term durability, making them the ideal replacement for RCF (refractory ceramic fiber).
Core Composition and Safety Principle: Scientific AES Formulation
CCEWOOL® bio soluble fiber blanket are manufactured from high-purity silica (SiO₂), magnesium oxide (MgO), and calcium oxide (CaO), precisely blended and melted to form AES fibers. Unlike conventional aluminosilicate-based RCF fibers, AES fibers are biodegradable: if inhaled into the lungs, they gradually dissolve in bodily fluids and are naturally expelled through human metabolic processes.
CCEWOOL® bio soluble fiber blankets have been certified by the Fraunhofer Institute in Germany and comply with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
Manufacturing Process: Precision Control Ensures Stable Performance
CCEWOOL® adopts an advanced one-step fiber-forming process, with strict control at every stage:
High-purity raw material selection and melting: Refined raw materials with metallic impurities strictly controlled below 1% are fully melted above 1500°C, forming a homogeneous liquid phase that guarantees compositional consistency.
Centrifugal fiber formation: High-speed spinning wheels draw the molten stream into micron-grade continuous fibers with uniform diameters, significantly enhancing blanket strength and thermal stability.
Integrated needling reinforcement: Fibers are evenly collected, then strengthened by a proprietary double-sided internal needling process to form a three-dimensional interlaced structure. This provides excellent tensile strength and resilience, ensuring easy installation and reliable maintenance.
Controlled heat treatment: Final products undergo carefully regulated heat treatment to release internal stress and enhance dimensional stability under high-temperature conditions.
Typical Applications: Widely Used in High-Temperature Equipment
Aluminum industry: Anode baking furnace (ABF) expansion joints, furnace door seals, castable back linings.
Metallurgy: Ladle covers, heat treatment furnaces, molten metal troughs.
Chemical and energy sectors: Cracking furnaces, gas turbine insulation, flue linings.
Civil applications: Fireproof curtains, insulation for nuclear power equipment, and more.
Through innovations in material science and manufacturing processes, CCEWOOL® bio soluble fiber blanket successfully balance the long-standing contradiction between high-temperature performance and environmental safety. They have become the preferred choice for thermal insulation upgrades in aluminum, metallurgy, power generation, and other industries. Representing the development trend of modern ceramic fiber technology, they also provide a reliable foundation for enterprises to advance green manufacturing and achieve sustainable development.
