Q: Which thermal stability of clay bricks and high alumina bricks is good?
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials. The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
Q: How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
Q: Why is the house made of refractory bricks not warm in winter
Heating equipment can be used
Q: Why can earth make bricks?
Therefore, it is still widely used in masonry projects such as walls, foundations and columns. However, due to the production of traditional clay brick to destroy the field, large amount of soil sampling, high energy consumption, brick from the major, high labor intensity and low efficiency in construction, it is necessary to gradually reform and replace with new materials. Some cities have banned the use of clay bricks in buildings. Brick for sintering brick and non sintered brick in accordance with the production process; according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, slag brick and lime sand brick; according to whether the hole is divided into hollow brick, brick. In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal.
Q: Clay brick, red brick, always fried brick how to do?
Clay brick and red brick are of very important quality and must not contain sand or gravel.
Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
Q: Can refractory be used to sharpen knife?
Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness
Q: What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
use castable refractory
Q: How to make refractory bricks? ? ?
Can knock, use angle grinder to slowly cut off the glaze layer outside the refractory brick, and then use hand to gently tap, to compare the complete China to do the work of the destruction of the situation
