What are the requirements for the production materials of breathable bricks?

Breathable brick is a new product with high lifespan, energy saving and consumption reduction, reasonable structure design, good thermal stability, erosion resistance, erosion resistance, and permeability resistance, high blow-through rate, safe and reliable operation, and long service life. Features.

First of all, in order to better ensure the permeability of the surface of the breathable brick, it needs to be manufactured in a steel infiltration mode in the ventilation channel, and in this process, we need to ensure the value of its steel infiltration. In order to control the relevant materials of the breathable brick, it can well control the wetting point of view with its molten steel; in addition, the function of the breathable brick will be affected by the environment due to the use of the environment. The strong erosion of the molten steel function, and then the material of the brick body in the manufacture, requires a sufficiently high structural function and related functions such as high temperature mechanics.

It is reported that this kind of high-function breathable brick is applied in an intermittent mode during use. Therefore, under the effect of acute cooling and heating, all materials of the brick body need to have strong thermal shock resistance. function and strong anti-shedding function, etc. Because of such good product function, and then in the later use and protection, it is necessary to carry out the burning oxygen cleaning effect, so as to improve the anti-oxidation function of the outer surface of the brick. Let it in the later production effect, can better improve the service life of its products.

Therefore, in order to better meet the various functions required in the process of use, in the manufacture of this kind of craft brick, it is necessary to effectively reduce the content of its fine powder, and at the same time add the required medium granular substances. At the same time, in the manufacturing process, the raw materials need to use plate-shaped corundum profiles, as well as fused zirconium and other corundum profiles as aggregates, and at the same time use a micro-powder material such as activated alumina. , as well as high-purity functional fused spinel, and a unique type of material such as chrome oxide green, to carry out the matrix ratio. In this process, we should pay attention to its cement chrome steel and other materials in this process. The proportion of the sintered alumina should be less than that of other corundum-type elements.
