Product Description:

Okorder series heat insulation brick

Okorder series thermal insulation brick is an effective, energy saving, low carbon, environmental protection advanced, according to the ASTM standard manufacturing products. Okorder series products have all kinds of materials in the field of metallurgy, industrial furnaces, aluminum, the best Li Ning petrochemical and insulation, electric power and glass ceramics. They can be used as part of an insulation or not to melt. Products have been widely used in the following furnace, achieved satisfactory results.

Application of heat preservation brick

Metallurgical Industry: blast furnace, hot blast furnace, heating furnace, etc..

Petrochemical Industry: ethylene cracking furnace, hydrogen furnace, the main furnace, heating furnace, etc..

Ceramic industry: roller kiln, kiln, etc..

Glass industry: glass furnace regenerator, etc.

Carbon industry: carbon furnace, etc..

Aluminum electrolysis industry: aluminum reduction cell, etc.

Other industries: tunnel kiln, shuttle kiln, etc..

Advantages of heat insulation brick

Low thermal conductivity: many air holes will bring good thermal insulation effect, energy saving.

High crushing strength: high crushing strength, volume stability.

Low heat storage: small heat storage, absorb more heat, energy-saving effect is obvious.

Chundu: High-speed Rail, low content of alkali metal impurities.

Accuracy: the size of the brick machining precision, cutting and grinding the special shape, speed up the brick.

Q:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
Of course, the market now has a lot of insulation bricks, and some insulation bricks can only do external wall insulation, such as sand, aerated concrete blocks. Some also only do the interior wall insulation, such as gray aerated concrete blocks, and some insulation bricks directly to the base, thus omitting the internal and external insulation, such as concrete composite insulation block.
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: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:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
And the concrete column junction should be concrete columns of the tie bar are removed after straightening up in brick joints.
Q:What is a JQK composite lightweight thermal insulation brick?
Its characteristic is waterproof and heat insulation, thermal insulation performance, strong decoration, waterproof effect is good, and good weathering resistance, long service life, the whole system of simple construction, low cost, is a new type of inverted waterproof and insulation structure of the current system state key application.
Q:What are the new types of building brick materials?
Sintered silt insulation brick, steam block, light building block, hollow clay brick, etc..
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:How much is a thermal brick
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:Energy saving bricks or bricks?
Insulating bricks are mostly hollow or light bricks.It can be said to be energy-saving bricks, including insulation bricks
Q:Is sintering insulation brick good or concrete porous brick good?
Thermal insulation brick is functional material, it is better than porous brick in thermal insulation. At the same time, the internal heat preservation material, so the overall cost is more, the hole brick should be higher.
