Product Description:

Refractory Brick

CMAX  firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation

Q:The structural specification does not indicate that masonry needs insulation bricks. Is it necessary to use insulation bricks?
Look at the exterior wall insulation design, construction practices and related requirements
Q:Material and making method of light insulating brick
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
Q:What's the difference between refractory bricks and insulating bricks?
In the preferred insulation performance, the thermal conductivity of insulating brick insulation brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better. In the degree of refractoriness, the refractoriness of insulating bricks is generally below 1400 degrees, while the refractoriness of refractory bricks is above 1400 degrees. In density, insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:There are several construction techniques for exterior wall insulation
Exterior wall sandwich insulation technologyThe exterior wall sandwich insulation is to place the heat preservation material between the inner and outer wall sheets of the outer wall, and the inner and outer walls can be made of concrete hollow blocks.Advantage:1) to the inner wall piece and the heat preservation material forms the effective protection, to the heat preservation material selection material request is not high (source: Chinese heat preservation net), polystyrene, glass cotton and urea aldehyde field casting material and so on may use;2) the construction season and construction conditions are not very high, and it does not affect the winter construction. In Heilongjiang, Inner Mongolia, northern Gansu and other cold areas have been given some applications.Shortcoming:1) in non cold areas, this kind of wall is thicker than traditional wall;2) the inner and the outer wall pieces need to be connected by connecting pieces, and the structure is more complicated than the traditional wall;3) periphery structure of "bridge" more. In the earthquake zone, building circle beam and constructional column settings, "bridge" more efficiency of thermal insulation materials is still not fully play.4) outside the walls by the outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking and leakage of rainwater.
Q:What is the bulk density of the sintered bricks?
The Dragon such high aluminum refractory brick density is generally around 1000, heavy refractory brick, high alumina brick HLGX heavy weight in general 2000Kg/m fand.
Q:Insulation brick should pay attention to external walls?
In each segment or block the tiles are from bottom to top paste, from the line of position the next layer of hypodermis first brick hidden good ruler, to hold the first leather tiles, pull in tile lines as the upper skin paste standard.
Q:What materials are used for roof insulation
There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
Q:Can the whole wall of the high-rise building be made of grey insulation bricks?
If the frame structure, it may be so. What is the length of the whole wall? If it is longer, it is necessary to make a constructional column; if the hole is larger, the edge of the hole needs to be made into a border or a constructional column; if the entrance is small, the edge of the hole is about 300mm and needs solid bricks to build better. South wall thickness can be about 190mm, plus plastering design value of 200mm. Personal comments for reference!
Q:If there is a main component of cenosphere light insulating brick.
Light heat insulation brick with cenosphere composition, material properties will be more high, especially the main properties of thermal conductivity
Q:Coke burns in a closed house. Will anyone suffocate in it?
Coke incomplete combustion can produce colorless gas carbon monoxide toxic odor. Carbon monoxide is a harmful gas. It will enter the body in the blood and hemoglobin, hemoglobin can combine with oxygen, cause the body tissue hypoxia, which causes the body to suffocation.
