Zirconium containing high-temperature resistant 1300 ceramic fiber paper and zirconium containing ceramic fiber gasket? Zirconium containing high-temperature resistant 1300 ℃ ceramic fiber paper "and" Zirconium containing ceramic fiber gasket "belong to high-performance high-temperature insulation and sealing materials, widely used in ultra-high temperature working environments such as metallurgy, petrochemicals, power, aerospace, glass kilns, etc. It is crucial to choose a source factory with technical strength and stable production capacity when making bulk purchases or selecting projects.
                                                                                       

Zirconium containing high-temperature resistant ceramic fiber paper is mainly composed of:

Aluminum oxide (Al2O3): ≥ 45%
SiO ₂ (silicon dioxide): ≈ 40%
ZrO ₂ (Zirconia): 15% -17% ← Key to improving temperature resistance
Mechanism of action of zirconium containing high-temperature resistant ceramic fiber paper:
ZrO ₂ forms a stable cubic crystal structure at high temperatures, inhibiting fiber grain growth;
Significantly reduce the linear shrinkage rate at high temperatures (1350 ℃ × 24h ≤ 2-3%, ordinary fibers can reach 5-8%);
Enhance the ability to resist creep and slag corrosion.

How to choose a ceramic fiber paper source factory based on the four core principles?

1. Do you have the production capacity for zirconium containing fibers?

The true source factory should have a resistance melting furnace or electric arc furnace, and be able to produce zirconium containing ceramic fiber cotton on its own (not reprocessed from purchased cotton).
Small factories are mostly engaged in "processing with supplied materials", resulting in significant fluctuations in quality.

2. Is there an authoritative testing report?

Must provide:
GB/T 3003-2017 Testing of Refractory Ceramic Fiber Products;
Chemical composition analysis (Al ₂ O ∝ ≥ 45%, ZrO ₂ ≥ 15%);
Linear shrinkage rate test (1350 ℃ × 24h ≤ 3% is preferred);
Environmentally friendly asbestos free declaration (compliant with RoHS/REACH).

3. Process control capability

Paper products: require vacuum filtration molding, with uniform fiber distribution and no layering;
Gasket products: require molding or CNC punching, with a dimensional tolerance of ≤± 0.5mm;
Supporting customized shapes (such as perforated, curved, multi-layer composite) is a bonus.

4. Engineering application cases

The four core standards teach you how to choose the source factory of 1300 ceramic fiber paper containing zirconium and high temperature resistance? Rosewool Insulation Refractory Co.,Ltd. is a trusted brand partner that requires objective evaluation based on its actual product capabilities, industry positioning, and technical strength; For a detailed understanding of the specific functional application solutions of ceramic fiber products, click on our online business platform or call our consultation hotline, and our professional staff will provide you with detailed answers;

Advantages and characteristics of 120K rock wool blanket as tunnel insulation material

What are the advantages and characteristics of 120K rock wool blanket insulation material for tunnels? The term '120K' here usually refers to high-density rock wool board/felt with a density of 120kg/m ³. In tunnel engineering, this high-density rock wool material is the core component of fire prevention and insulation systems. In actual tunnel engineering, 120K rock wool blanket is often used as the core filling material for tunnel fireproof board (i.e. "rock wool sandwich fireproof board"), or directly as a spray/adhesive insulation fireproof layer.

External wall insulation composite aluminum foil rock wool board, 20mm thick

Is the external wall insulation composite aluminum foil rock wool board 20mm thick? The composite aluminum foil rock wool board (20mm thick) is an insulation board made of high-density hydrophobic rock wool as the core material, with one or both sides covered with high reflectivity aluminum foil (usually embossed aluminum foil). It is commonly used for thermal insulation, moisture prevention, and energy conservation in areas with limited space.
