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: Is the quality of refractory brick influenced if it is soaked by water
Refractory bricks shouldn't be got wet by damp. Other refractory brick is not much problem, after touching, please wash hand, or masonry stove ignition will burst. In addition, refractory bricks containing chromium can't meet water, it's easy to hydrate and scrap, it will generate Cr VI ( chromium VI ), which is hanrmful to health and pollutes the environment, but try not to get wet
Q: Do refractory bricks need to be sent to the lab to test after arriving the site?
Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need
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: why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
Q: 90 porous brick and ordinary shale brick, clay brick difference
Porous brick refers to clay, shale and fly ash as the main raw material, porous brick after molding, roasting and hole rate of not less than 15%~30%, the pass is a round hole or non circular hole, the small size and number of loading sintered porous brick has a rectangular or circular hole, is not equivalent to as long as the bricks some hole. The utility model can directly replace the sintered clay brick, and is widely used for various bearing, thermal insulation, bearing and frame filling construction walls with wide popularization and application prospect.
Q: What kinds of annealing furnace refractory bricks there are?
But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick
Q: Are refractory bricks necessarily needed to build a kitchen stove?
It will be better to use refractory bricks for long term because of its high temperature resistance
Q: What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
Withstanding voltage strength is not the same, the strength of the mechine-made is higher
Q: Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
The following buildings plus or minus zero use of clay bricks is used because the clay brick has good water absorption, can make the capillary water in the soil up to the clay brick, clay brick is absorbed, so as to prevent the capillary water rising effect
