$Refractory Fireclay Brick with Al2O3 content 45%$

Q:With what three clay brick clay brick with six holes under what circumstances?: Different specifications, different strength, and use in different structures.

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

Q:What is the difference between a clay brick and a red brick?: Clay bricks burn red and red brick. Burnt blue. Green brick.Clay bricks are called sintered clay bricks.The construction methods are the same as those of the two. No difference.

Q:How to built refractory bricks as fitting between square and circle ducts: Use rectangle at the bottom and knife type for the top. trapezoid for junction.

Q:Are refractory bricks poisonous?: Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive

Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?: The proportion of refractory bricks is related to the density.

Q:What's the reason of cracks in refractory bricks?: The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious

Q:What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?: The effect of adding andalusite is better

Q:What are the specifications of clay brick and cement brick construction?: Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".

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.
