To introduce the nextpolycrystalline mullite fiberEnvironmental requirements for storage

How does polycrystalline mullite fiber achieve heat insulation function?

Polycrystalline mullite fiber is a new type of refractory materials in the leader, stable performance, affordable, so cost-effective refractory material how to achieve the insulation function.

1. Fiber conduction and heat transfer: due to thispolycrystalline mullite fiberThe ceramic fibers in the paper have no directionality, so they exist in all directions. At the same time, heat is transferred along the fibers, and the fibers are rarely perpendicular to the hot surface. In addition, the fibers overlap each other, increasing the thermal resistance of heat conduction. Therefore, the heat conduction of the ceramic fiber paper is not significant.

2. Fiber radiation heat transfer: The fiber in the ceramic fiber paper is not bright, so that the heat ray cannot penetrate the fiber, the fiber is very thin, it cannot accept heat radiation well, and the heat transfer effect is not significant.

3. Gas convective heat transfer: As the ceramic fibers overlap each other, many air chambers are formed inside the polycrystalline mullite fibers. These air chambers store a large amount of air, so that the air cannot flow freely and will generally stop relatively. The heat absorbed by the gas can only be transferred through conduction. Due to the small thermal conductivity of the gas in the stopped state, polycrystalline mullite fibers cannot use gas for heat transfer.

What are the requirements for the storage environment for polycrystalline mullite fiber blankets?

Polycrystalline mullite fiber felt is a brand-new refractory fiber product with relatively stable performance. Only when you buy it, you need to buy it in many places. After all, it is more convenient to use it for repairs. Of course, storage is a problem when the purchase volume is large. In addition, this material should be stored carefully. The small editor will introduce the requirements of polycrystalline mullite fiber felt for the storage environment, so that everyone can rest assured.

　　polycrystalline mullite fiberFelt has the characteristics of high temperature resistance, strong impact resistance, good ductility, good fire resistance and wear resistance, and good heat insulation. It is mainly used in aviation, high temperature manufacturing and other industries with high product requirements. As a company that produces a large number of needled blankets For manufacturers, we must do a good job in inventory and product maintenance in order to provide customers with better products.

Polycrystalline mullite fiber blankets are generally placed in the warehouse of the manufacturer, but different products have different requirements for the warehouse environment. The needle blanket is mainly aluminum silicate. Although it has certain anti-corrosion properties, it cannot be mixed with strong alkali and strong acid in some storage, which will cause the needle blanket to fail. Second, the warehouse should not be too humid or directly exposed to the sun. Both are not conducive to the storage of the needle blanket, which will cause the product to crack or mold, two extreme environments should be avoided, and its packaging and dustproof technology should be well done.
