Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
Q:What are the differences between high alumina brick and high alumina refractory brick?
High alumina brick is generally the national standard T-3 models, high alumina refractory brick is brick with more than 55% of aluminum content including special-shaped brick.
Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:General used refractory brick T-20 / T-39/ T-206 specifications and dimension
No T-206 model (we produce the clay) T-20 and T-39 are the size of 230*length, 113* width and 65/45 thickness, T-20 is a vertical arch brick and T-39 is horizontal arch brick.
Q:What are the reasons for the production of waste in the formation of fireclay bricks?
The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.
Q:What is light brick and what are the characteristics of light brick?
The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
Q:What building materials can take the place of clay bricks?
Housing grades have been upgraded, heat preservation, sound insulation, heat insulation, seismic, energy-saving performance fully reflected, can improve the selling point of commercial housing 3%, in the major cities in China has become the preferred condition of user purchase.
Q:What are the physical and chemical properties of refractory bricks
The thermal shock stability, linear change on reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness
Q:Are buildings allowed to use red bricks?
Clay brick is forbidden to be used by the state, whether red or green. Red and cyan are just the difference between making techniques. Now also produces appearance and clay sintering, red brick like silicate sintered brick can be used.
