Ceramic fiber board is a good fire-resistant material, with strong performance, so generally speaking, it does not suddenly appear chapped during use. Therefore, if the sudden occurrence of chapping occurs when the plate is used, then the material quality of the plate is not up to standard, and there is a problem of determination, which cannot be continued to be used. So, what is the cause of the sudden chapping of the plate when it is used? Topower—Ceramic Fiber Board manufacturers tells you the answer.
1. In the grinding process of fiberboard, due to the amount of feed is too large, resulting in insufficient cooling, so that the surface to form a large thermal stress and organizational stress, superimposed on the residual stress, easy to cause grinding cracks.
2. In the process of heat treatment of ceramic fiber board, due to high temperature, resulting in carbides all dissolved, coarse grain; At the same time, tempering is not enough, resulting in the increase of residual stress and brittleness;
3. The wrong use can result external force to cause the plate in the use of sudden chapping.
Therefore, whether it is in the purchase of ceramic fiber insulation board, or before use, we should do the relevant inspection to determine that the quality of the board purchased and used is not a problem, and then it can be used in accordance with the correct way of use, so as to avoid the sudden cracked phenomenon of the board in the process of use to a large extent.
In addition to the corresponding loose ceramic fiber cotton excellent performance, the Ceramic fiber board is hard, has better toughness and wind erosion resistance is also better, and heating does not expand, light weight, convenient construction, can be arbitrarily shear bending, is an ideal energy-saving material for kiln, pipeline and other thermal insulation equipment.
When ceramic fiber board is used for the first time, light smoke will appear when the component temperature exceeds two or three hundred degrees, which is caused by the combustion and volatilization of organic matter in ceramic fiber board, and then it becomes brown in a short time, and aluminum silicate will naturally return to the original white after 1-3 days of operation, which will not cause any impact on product quality.
The furnace lining construction speed is accelerated, the weight of the kiln is reduced, and the fire-resistant performance of the kiln is greatly improved. Users can use different fiber modules according to the kiln structure, Topower Refractory can provide multiple varieties, multi-system ceramic fiber board, can also be processed according to user requirements.
