Differences Between Soluble Fiber Blanket and Traditional Fiber Blanket

1. Composition and Environmental Friendliness

▶ Soluble Fiber Blanket: Mainly composed of SiO₂, CaO, and MgO. Biodegradable, compliant with environmental regulations, and reduces long-term pollution risks.

▶ Traditional Fiber Blanket: Mainly composed of aluminosilicate (Al₂O₃-SiO₂). Non-degradable, difficult to dispose of after use, and has high biological persistence.

2. High-Temperature Resistance

▶ Soluble Fiber Blanket: Can withstand temperatures of 1200–1300°C, shows no shrinkage after 2 hours at 1000°C, and has a low thermal conductivity (0.08 W/(m·K)).

▶ Traditional Fiber Blanket: High-temperature performance is similar, but products with higher Al₂O₃ content are more stable under extreme temperatures (though environmental concerns remain).

3. Mechanical Properties and Processability

▶ Soluble Fiber Blanket: Tensile strength ≥150 kPa, slag ball content <10%, soft texture, easy to process into various shapes.

▶ Traditional Fiber Blanket: Mechanical properties vary by product; some fibers are coarse and rigid, with slightly higher skin irritation.

4. Chemical Stability

▶ Soluble Fiber Blanket: Resistant to acid and alkali corrosion (mass loss <5% after 72 hours in pH 2–12 solution), suitable for chemical and metallurgical applications.

▶ Traditional Fiber Blanket: Chemical stability depends on composition; performance may decrease in strong acidic or alkaline environments.

5. Application Scenarios

▶Soluble Fiber Blanket:

Industrial furnaces (easy removal, cost reduction)

Fireproof construction (environmentally friendly, no waste)

Aerospace (fire-resistant and biodegradable)

▶Traditional Fiber Blanket:

Traditional high-temperature industries (with increasing environmental pressure)

Building insulation (limited by non-degradability)
