Share:
In the high-temperature industrial sector, high-quality thermal insulation materials are crucial for ensuring production safety and enhancing energy efficiency. The ceramic fiber blanket meticulously crafted by Rosewool Insulation Refractory Co.,Ltd, with its exceptional performance and reliable quality, has become the trusted choice of numerous enterprises.
  •  Product Ingredients and Production Process
Our ceramic fiber blanket primarily utilizes high-purity aluminum silicate fibers as raw materials. Through advanced spinning or blowing processes, the molten raw materials are transformed into fine and uniform fiber threads. These fiber threads undergo a special double-sided needle punching process, interweaving and entangling with each other to form a tight and elastic blanket-like structure. The entire production process strictly follows the ISO quality management system, ensuring that each batch of products meets high quality standards.
                                                                                  
  • Product Features
  1. Excellent high temperature resistance: It can continuously withstand high temperature environments up to 1260℃, and its instantaneous temperature resistance can reach as high as 1400℃. Under such intense working conditions, the product can still maintain a stable physical form, without melting, deformation, or embrittlement, providing durable and reliable protection for high temperature equipment
  2. Excellent thermal insulation performance: The internal fibers are arranged in a three-dimensional interlaced pattern, creating countless tiny air chambers. This unique structure greatly hinders heat conduction, with a thermal conductivity reduced by more than 40% compared to traditional insulation materials. It can effectively reduce heat loss from equipment and lower energy consumption
  3. Lightweight and flexible: The product has a low density of 0.1 - 0.2g/cm³, with a soft texture that is easy to cut, roll, and fold. Whether it's wrapping complex-shaped pipes or filling irregular equipment gaps, it can easily conform to the shape, facilitating convenient construction and significantly shortening the installation period
  4. Excellent chemical stability: It exhibits outstanding resistance to most acids, alkalis, and corrosive gases. In harsh environments such as chemical and metallurgical industries, it remains undamaged from chemical erosion, boasting a long service life and low maintenance costs
  5. Environmentally friendly and safe without hazards: It does not contain harmful substances such as asbestos. During production, installation, and use, there is no dust flying, and it poses no harm to human health or the environment. According to tests conducted by authoritative institutions, the toxicity of the flue gas reaches AQ1 level, and it does not release toxic gases even at high temperature
