How is Silica Aerogel Paper Made?
The advanced production process (patented technology ) addresses traditional manufacturing flaws:
Substrate Preparation: Fiber paper (ceramic/glass fiber) is coated with a water-repellent, breathable membrane .
Aerogel Prepolymer Synthesis: Silica source (e.g., tetraethyl orthosilicate) is mixed with solvent, water, and catalysts to form a uniform solution .
Composite Formation: The prepolymer is infused into fiber paper via ultrasonic vibration (40-80Hz), reducing impregnation time from 2-10h to 15-50min .
Modification & Drying: Solvent replacement and alkylation treatment enhance hydrophobicity; drying via supercritical or atmospheric methods preserves porous structure .
New Energy & Transportation
EV battery packs: Thermal insulation between cells to prevent thermal runaway .
Aerospace: Insulation for missile high-temperature batteries and fighter jet engines .
Electronics & Precision Instruments
Thermal management for narrow spaces in semiconductors and medical devices .
Space-Saving: Ultra-thin design (0.1mm) fits complex curved surfaces .
Cost-Efficient: Long lifespan and low thermal loss reduce operational costs .
Eco-Friendly: No volatile additives, recyclable substrates .
Maintenance and Care
To ensure the longevity and effectiveness of fiberglass insulation paper, proper maintenance and care are essential. Here are some tips:
Inspect Regularly: Regularly inspect the insulation paper for signs of damage, such as tears, holes, or water damage. Repair any damage promptly to prevent further deterioration.
Keep Clean: Keep the insulation paper clean by vacuuming or brushing off dust and debris. Avoid using water or cleaning agents that could damage the insulation.
Protect from Moisture: Moisture can damage fiberglass insulation paper. Ensure that the insulation is properly sealed and protected from moisture sources, such as leaks or condensation.
Avoid Compression: Avoid compressing the insulation paper, as this can reduce its insulation effectiveness. Ensure that there is enough space for the insulation to expand and provide proper insulation.
FAQ:
What core safety issues can using Silica Aerogel Paper in EV battery packs address? Is there data to support its specific effectiveness?
It primarily addresses the "thermal runaway" problem in EV battery packs. When thermal runaway occurs, the material can withstand transient temperatures of 1200°C and block heat transfer between battery cells within 56 seconds, creating a critical safety barrier for the battery module. This feature effectively reduces the overall fire risk of the battery pack and compensates for the lack of flexibility and inability of traditional thermal insulation materials (such as ceramic sheets) to conform to the curved surfaces of battery cells.
What parameters can be customized for Silica Aerogel Paper? What specifications can companies adjust based on their purchasing needs?
Currently, we support multi-dimensional customization. Core adjustable parameters include: ① Thickness: Customizable within a range of 0.1-5.0mm to accommodate the tight spaces of various devices; ② Packaging: Adjustable roll sizes from 0.3-1m³/roll are available to accommodate both mass production and small-batch trials; ③ Base material selection: Ceramic fiber or glass fiber can be selected based on the operating environment (e.g., high temperature, high humidity). Furthermore, to meet customer requirements for higher hydrophobicity, the hydrophobicity can be increased to 99% (standard: ≥98%).
