Q:What are the advantages and disadvantages of clay bricks?
Disadvantages of clay bricks1., since the majorCompared with other masonry materials, the weight of the clay brick is relatively large, so the structure needs to bear heavy deadweight, and the cost of the building increases. 2., poor sound insulation effectSound travels to the clay brick, because of its low porosity, without isolation of sound, sound decibel little drop, while other building materials such as now used more concrete block filling the void ratio is large, sound insulation effect is obvious.3, environmental destructionBecause clay bricks are mainly sintered by excavation soil, soil erosion and damage to vegetation have resulted in soil erosion and serious damage to the environment. Therefore, the country is gradually stopping the project to use clay bricks.
Q:The state's policy on clay bricks
Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:What are the materials for building blocks and what are the specifications?
Material: clay brick, shale, coal gangue brick, fly ash brick, lime sand brick, concrete brick etc..
Q:Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
The burner block is heavy, its using temperature is high, while thermal insulation brick is light and its using temperature is lower than heavy brick.
Q:Why can't build refractory brick behind the skew block?
Refractory is heat expansion and cold contraction, when it is high temperature, it will squeeze toward the center and the vault will be deformation .
Q:The matching ratio of masonrying refractory bricks cement
When building refractory bricks, use matching chamotte, do not use cement
Q:can castable refractory replace refractory bricks in rotary kiln?
No, there is expension gap between bricks, and that is no solution when the castable refractory expend.
Q:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
use ceramic fiber precast block
Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Heat insulation cotton is laid behind refractory brick.
