Ceramic fiber board, as a kind of high-performance thermal insulation material, is widely used in the industrial field. This article will provide you with a detailed introduction to the key elements of the purchase of high-quality ceramic fiber board, to help you make a wise choice.
Clarify the use of temperature requirements
Selection of ceramic fiber board should first consider the use of temperature. Ordinary ceramic fiber board temperature is usually about 1000 ℃, and high-purity ceramic fiber board up to 1260 ℃, containing zirconium ceramic fiber board can withstand high temperatures of more than 1400 ℃. According to the actual working conditions to choose the appropriate temperature-resistant grade of ceramic fiber board, to avoid material failure due to high temperature.
Focus on physical performance indicators
High-quality ceramic fiber board should have the following characteristics: low thermal conductivity (usually ≤ 0.12W/m-K), high compressive strength (≥ 0.3MPa), low heat capacity and excellent thermal stability. When purchasing, you can ask the supplier to provide a detailed performance test report to ensure that the ceramic fiber board meets your technical requirements.
Check the appearance quality
Ceramic fiber board of good quality should have a flat surface without cracks, delamination or obvious impurities. Tap the surface of the board with your finger, the sound is good. Poor quality ceramic fiber board is often uneven density, easy to fracture or deformation problems. It is recommended to choose a well-known brand of ceramic fiber board, the quality is more guaranteed.
Consider the special treatment process
According to the use of the environment, you can choose the ceramic fiber board after special treatment. For example:
Waterproof ceramic fiber board (add hydrophobic agent)
Reinforced ceramic fiber board (add reinforcing fiber)
Low slag ball content ceramic fiber board (reduce dust)
Certification and Environmental Requirements
High-quality ceramic fiberboard should pass ISO9001 quality management system certification, and some high-end products also have CE, ROHS and other international certifications. Environmentally friendly ceramic fiber boards should comply with national environmental standards and do not contain harmful substances such as asbestos.
Suggestions for Supplier Selection
It is recommended to choose manufacturers with many years of production experience, who can not only provide ceramic fiber boards with stable quality, but also recommend the most suitable product specifications according to your specific needs. You can ask the supplier to provide samples for testing to ensure that the ceramic fiber board meets the requirements of actual use.
Through the comprehensive consideration of the above aspects, you will be able to purchase ceramic fiber boards with excellent performance and reliable quality to provide the best thermal insulation solution for your project.
