- Q: How to distinguish between sintered clay brick and sintered coal gangue brick
- Sintered coal gangue brick with coal gangue as main raw material, sintering after selection, crushing, molding, drying and baking into non clay brick. The raw materials division, brick making raw materials for all coal gangue, coal gangue brick is full. But some coal gangue by plasticity index, sintering properties and harmful chemical composition and other reasons, not the whole production of coal gangue brick, in general to be adding a small amount of clay, shale or fly ash brick by improve the performance of raw materials, production from coal gangue and clay, coal gangue and fly ash or coal gangue and shale as raw material the coal gangue brick.
- Q: what is consequence of high load and soft low of high alumina refractory brick ?
- softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
- Q: What are the differences between thermal?insulation?bricks and refractory bricks?
- Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.
- Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
- Heat insulation cotton is laid behind refractory brick.
- Q: What is the coefficient of heat transfer for clay bricks?
- The heat transfer coefficient of clay brick is about 0.8.
- Q: What is the difference between clay brick, glazed tile and brick?
- Clay bricks are actually a kind of clay bricks, mainly made of solid bricks! It is a product of continuous optimization of products and upgrading of traditional techniques. Usually made of high quality clay and clay brick clay high temperature firing, using natural clay as main component, quartz and feldspar as aggregate, construction bricks after sintering the formed. The nature of clay brick belongs to low temperature brick, the burning temperature is about 800 degrees Celsius, the water absorption rate is higher, and the general water absorption rate is 8%--10%.
- Q: What are the sizes and sizes of clay bricks?
- At present, with the minimum size of the maximum size of the market, for the maximum size of the clay brick, there are 600*250*200mm, 180*115*90mm, 300*300*55mm, and the minimum sizes 150*150*150mm, 235*115*55mm and so on, the construction industry the most basic materials for clay brick, must use in daily life is very broad.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
- High temperature resistance can also extend its service cycle. If there are conditions for the user heat resistant steel welding nails. By using high temperature high alumina brick, expansion joints can not be too large, with high-temperature adhensive paste masonry, recommend that you use the refractory brick, add the amount of long pieces of brick or rachel brick
- Q: Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
- The clay brick has a certain strength, and has better heat insulation and sound insulation performance, and the interior wall of the winter can not appear condensation phenomenon, and the price is low. Although a variety of new wall materials are emerging, clay bricks will still be used as a main material for masonry work in the future
