Ceramic fiber blanket, as a flexible refractory insulation material, is a necessary insulation material for various electric heating equipment and high temperature pipelines.
Many friends may ask, is n’t it better to use ceramic fiber blankets for high-temperature pipe insulation, and it is also convenient for wrapping. actually not.
The density of ceramic fiber blanket is 128kg / m3, and the density of ceramic fiber paper is 200kg / m3. It can be seen that the porosity of ceramic fiber blanket is much larger than that of ceramic fiber paper, which means that the thermal insulation performance of ceramic fiber blanket is higher than that of ceramic fiber paper. .
Therefore, except for thinner pipes or small and fine heating equipment, ceramic fiber paper must be selected as the insulation layer, and ceramic fiber blankets are recommended for other medium and large-scale pipeline insulation.
So here comes the problem. We all know that ceramic fiber blankets have prescribed dimensions at the factory, such as 20mm thick is 7200 * 610 / 1220mm, 30mm thick is 5000 * 610 / 1220mm, and 50mm thick is 3600 * 610 / 1220mm.
If the amount of some special specifications is small, the manufacturer does not provide customization. Even if it can be customized and the cost of equipment adjustment is added, the price is staggering.
In fact, don’t worry about this problem. Ceramic fiber blankets can be processed by themselves. There is only a utility knife between the high price and the normal factory price. You can freely cut into any shape you need. This is a place where ceramic fiber blankets are more flexible and easy to install and use.
