Product Description:

Specifications

1.Passed ISO 9001;
2.57% Alumina content,or as customized;
3. Carborundum Fire Brick is widely used in iron-making.

AL2O3SiCC carborundum fire brick are universal materials for the lining of molten pretreatment equipments of molten iron tank, torpedo car, etc. The products are shaped by machine power by using dense bauxite clinkerand brown fused alumina as base materials and adding high quality SiC fines and high purity glake fraphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.

Carborundum products belong to high grade refractory material,maximal use temperature is 1500°C,it has excellent thermal conductivity,heat shock stability,high load softening point and very good wear-resisting property,widely used in various industries with special requirement.

Q:Several kinds of energy-saving bricks
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.
Q:What are the types of building blocks?
Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)
Q:What is the exterior wall insulation material made of graphite?
Graphite polystyrene (SEPS) containing graphite particles special, can be like a mirror which contains thermal radiation, and can greatly enhance the heat insulation performance of the infrared absorption, thereby reducing the heat loss of housing. Its insulation capacity is at least 30% higher than the average EPS, helping to increase energy efficiency and reduce carbon dioxide emissions.
Q:What is the price of concrete self insulation bricks
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
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:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
Recently, a lot of people have encountered this problem, Silver Horse understand, in fact, the brick machine is only the production of different production, the quality of the bricks produced are the same.
Q:Difference between inorganic insulation material and organic thermal insulation material
1, organic insulation material with light weight, good processability, high compactness, good insulation effect, but the disadvantage is: aging resistance, deformation coefficient, poor stability, poor security, easy combustion, ecological environmental protection is poor, difficult construction, construction cost is higher, and the limited resources. It is difficult to recycle.2, inorganic insulation materials with energy-saving, waste, heat insulation, fire protection, antifreeze, anti-aging and excellent performance, as well as low prices and other characteristics, can achieve A-level fire protection, has a wide range of market demand.
Q:Which kind of balcony heat preservation material is better?
To environmental protection, then use inorganic insulation materials, such as composite silicate, rare earth insulation, this thickness should be more than 5 cm, the construction of auxiliary materials, high cost, to be strengthened
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:Is the building built of cement hollow board safe?
If the use of material quality unqualified cement hollow board, the construction process of Jerry building, even with good material, there will be security risks;
