High purity quartz wool: excellent insulation and high temperature resistance solution
Are you facing these challenges?
Q: Are you looking for an insulation material that can maintain stable performance in extreme high temperature environments?
Answer: High purity quartz wool can be used for a long time at a high temperature of 1650 ℃, with a short-term temperature resistance of up to 1750 ℃, providing you with reliable high-temperature protection.
Q: Are you concerned about impurities in insulation materials contaminating your production environment or products?
Answer: We use high-purity quartz raw materials with a purity of over 99.95% to ensure that the material is free of alkali metals and has low boron content, avoiding secondary pollution.
Q: Do you need a lightweight and efficient insulation solution?
Answer: The density range of quartz wool is 80-200kg/m ⊃3;, which combines excellent insulation performance and lightweight characteristics to reduce equipment load.
Q: Are you troubled by customizing irregular insulation components for complex equipment?
Answer: We provide full-size customization services, which can be processed into various forms such as boards, felt, pipes, and shaped parts to accurately match your needs.
Product Overview
High purity quartz wool is an inorganic fiber material made from high-purity natural quartz (SiO ₂ content ≥ 99.95%) through high-temperature melting and fibrosis. Its unique amorphous structure and chemical stability make it an irreplaceable insulation, filtration, and filling material in the high-temperature field.
Key performance parameters
-Maximum operating temperature: long-term 1650 ℃, short-term 1750 ℃
-Fiber diameter: 3-8 μ m (customizable)
-Density range: 80-200kg/m ⊃3;
-Thermal conductivity: 0.035-0.055 W/(m · K) @ 500 ℃
-Chemical composition: SiO ₂ ≥ 99.95%, Fe ₂ O3 ≤ 0.005%, Al ₂ O3 ≤ 0.05%, alkali metals ≤ 0.01%
-PH value: neutral (6.5-7.5)
-Moisture content: ≤ 0.5%
Product Advantage Analysis
Excellent temperature resistance performance
Quartz fibers manufactured using special processes have higher softening points and lower high-temperature shrinkage rates. In a continuous working environment at 1650 ℃, the linear shrinkage rate is less than 1%.
Ultra high purity guarantee
The raw materials undergo three purification processes, and the content of key impurities is controlled at the ppm level:
-Alkali metals (Na, K, Li): ≤ 100ppm
-Transition metals (Fe, Ti, Cr): ≤ 50ppm
-Boron (B): ≤ 10ppm
Excellent thermal stability
The coefficient of thermal expansion is only 0.54 × 10 ⁻⁶/℃, much lower than that of ordinary glass fiber (5-8 × 10 ⁻⁶/℃), and it is not easy to crack under rapid cooling and heating conditions.
chemical inertness
Except for hydrofluoric acid and hot phosphoric acid, it is resistant to acid, alkali, and most chemical media corrosion, and can remain stable in both reducing and oxidizing atmospheres.
Low heat capacity and low thermal conductivity
The porous fiber structure stores over 85% of air, significantly reducing heat storage and conduction, and improving energy efficiency.
