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:Advantages and disadvantages of wall insulation system?
Disadvantages: poor insulation effect (because it is not a full coverage of the insulation layer), there will be condensed water (because the wall is cold, the heat insulation layer is the temperature difference between inside and outside the formation of condensed water), the decoration (insulation layer in the internal decoration of the time on the wall decoration will destroy the insulation layer, comprising an area of effect) (rules of the construction area).
Q:What are the new types of building brick materials?
The whole material made of brick and mortar is one of the most widely used building materials. According to whether the masonry is reinforced, it is divided into unreinforced brick masonry and reinforced brick masonry.
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:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
There is no mandatory requirement, but the thermal insulation system should use expansion bolts to do the pullout test, and the exterior wall tiles also need pullout tests.
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: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;
Q:How to do indoor thermal insulation
Indoor thermal insulation, as well as "folk prescription""Some owners also used some of the insulation sleeves, for example, light reflection, heat is also, by means of a reflected heat, indoor temperature increase, the specific approach is adopted, Kouban metal surface, can also use the kitchen stove using metal film or metal film for baking food, installed in the radiator the walls and the walls, so that the heat preservation and reflection cooling effect, but also does not affect the appearance. Again, the 40% heat and window glass heat loss on indoor winter, especially some French families, the feeling of winter indoor temperature is relatively low, methods can be used to paste glass insulation film and coated glass insulation coating to retain heat.
Q:How to reinforce a porous brick foundation?
Increase depth method: for immediate lower layer is a good soil bearing situation, while the best bearing layer in groundwaterBit line above.
Q:What are the insulation materials for heating buried pipelines?
The heat preservation layer is composed of antirust paint, heat insulating material, moisture-proof layer (used for pipeline in the trench), protective layer, anticorrosive layer (used for trench or directly buried pipe) and top coat (or fireproof coating).The waterproof layer can be used asphalt or aluminum foil protective layer with glass cloth or galvanized steel.
Q:What are the specifications of high strength diatomite insulating bricks?
Exterior wall insulation decorative board insulation performance is very good, and the processing method, anchor node and patent products cold bridge design reduces the energy loss, therefore, especially in the area of bad weather such as the northeast, northwest and other places, energy-saving insulation requirements are very high, the traditional thermal insulation construction has brought great difficulty to the construction.
