Crystal fiber manufacturers take you to understand the basic knowledge of crystal fiber

Crystal fiber is a term that is often heard in the material market in recent years, but there are still people who do not understand this material. Crystal fiber manufacturers will take you to understand the basic knowledge of crystal fiber, so that everyone can have a comprehensive understanding of this material widely used in thermal equipment such as industrial furnace cellar.

What are the classification of polycrystalline mullite fiber?

Polycrystalline mullite fiber is a kind of polycrystalline alumina fiber. The content of Al2O3 in the fiber is between 72% and 75%, and the content of Al2O3 generally exceeds 80%, which is called polycrystalline alumina fiber.

Classification of Polycrystalline Fibers

PMF (Polycrystalline Fiber) is the latest ultra-light heat-resistant insulation material in the world. It consists of mullite microcrystals. Polycrystalline fiber It combines the characteristics of crystalline materials and fibrous materials with excellent thermal stability. The use temperature is 1500 ℃, the melting point is 1840, the thermal conductivity is 1/6 of the traditional refractory brick, and the bulk density is only 1/25 of the traditional refractory brick. It is an ideal material for high temperature furnace to save energy and increase production.

Application of Alumina Fiber

As one of the seven strategic emerging industries in China and one of the ten key areas of "made in China 2025" and the key areas in the 13th five-year National Science and Technology Innovation Plan, the new material industry is the industrial foundation for the transformation and upgrading of the whole manufacturing industry. The core manufacturing technology of alumina fiber needling blanket has been tightly blocked by developed countries due to its outstanding product advantages, while China has long relied on imports for this product. A very large application market for alumina fiber needled blankets is the three-way catalytic converter sealing gasket in exhaust gas treatment equipment in the high-end automobile industry. At present, the sealing gasket in the automobile industry is made up of Mitsubishi of Japan, IBIDEN of Japan, and 3 of the United States.

Do you know anything about fire blankets?

Fire blanket generally has: flame retardant, corrosion resistance, high temperature resistance, structural stability, tensile flexibility, high strength and a series of advantages. In addition, the fire blanket has some features other than its functions, you know! Follow Xiaobian to continue to understand it! Environmental protection: This is particularly important. Fire blanket, in the process of fire prevention, will not produce harmful gases, resulting in the impact on the human body. 2. Long-term: household fire escape blanket is once and for all products, will not fail. If there is a time limit with the second fire extinguisher, the powder must be replaced in one year, otherwise it will not work.

Ceramic fiber is not the higher the density, the more durable?

Ceramic fiberboard generally has a density of 280-550. When used as a heat insulation layer, the density is generally 280-350. Because there is no need to see fire, the strength requirement is not too high, and this density is also the density with the best heat insulation performance. If the density is higher or lower, the heat insulation performance will decrease. For refractory layer, the density should be appropriately increased with the temperature requirement to improve the service life, but it is not necessary to choose too large density, on the one hand, the density is too high, will make the thermal conductivity increased, resulting in lower insulation performance, on the other hand, the density is too high, will lead to ceramic fiber board hardness increased, but will be more likely to crack, so
