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:There are several construction techniques for exterior wall insulation
Exterior wall internal insulation technologyThe interior heat preservation of the wall is to place the heat insulation material on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the energy transformation of existing buildings, especially at a time when the housing sold to individuals, the whole building (source: China insulation network) or the entire district unified reform is difficult, only by the possibility of a large number of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:What kind of material is clay insulation refractory brick made of?
Alumina silicate refractories with a content of 30% ~ 46% are called clayey refractories. Clay products are mainly made of mullite, glass phase, square quartz and quartz.
Q:What is the price of refractory bricks
Insulating brick is a refractory brick often used in kilns to reduce the heat loss of kilnsSo as to ensure the practical efficiency of kiln and bring more benefits.There are many kinds of thermal insulation bricks, and there are many refractory manufacturersAs to how much bricks should be paid, a detailed consultation should be made to the refractory bricks manufacturerHave some understanding of the properties, technologies, raw materials and so on, and make a decisionDifferent types of insulation brick prices are different, the price is relatively cheap, lightweight clay insulation brick 1The market price is 1.3 yuan a pieceThe price of mullite heat preservation brick 0.8, the market price of 4.62 yuan a pieceDepending on the area, the price of insulating bricks will fluctuate somewhat
Q:What are the bubble bricks?
The steam free aerated block has the advantages of wide raw material sources, high waste rate and low cost. With fly ash, slag, sand, sand, soil containing low amount of powder and tailings as the main raw materials (with one can), local materials, low cost, high profit.
Q:The difference between ordinary and diatomite brick refractory brick?
Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
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:Material and making method of light insulating brick
The strength products are made of high quality tabular corundum and mullite as aggregate, silicon carbide as matrix, additional special additive and a small amount of rare earth oxide to be mixed, and then formed by high pressure molding and high temperature sintering.
Q:Why does the water drop first and then rise when the boiler fires?
Often in the operation of the boiler, the steam water mixture to the drum after intense evaporation of a large number of bubbles in the water side, the water volume expansion. By actual water level drum water level indicator is higher than the water level
Q:What is the thermal insulation performance of aerated bricks?
Because of the hollow characteristic, the aerated brick is flexible, and the main body of the building is supported by the reinforced concrete structure, and the brick is only filled. When the earthquake occurs, the reinforced concrete structure will be deformed, and if it is a solid brick, the deformation of the reinforced concrete structure will be broken and collapsed when it is overstock. The use of hollow brick can give the reinforced concrete structure to leave a very good space for expansion.
Q:What's the price of lightweight refractory bricks?
In addition, general price comparisons are meaningless and need to be based on the use of demand = quality of products. After all, good quality is the driving force of continuous production.
