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:Are there any construction waste materials for composite thermal insulation bricks?
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 is the difference between cement foamed thermal insulation board and thermal insulating brick?
1, cement foam insulation board, as its name says, is "board", it is used on the exterior wall or roof, that is, the grass-roots has been done, and put a plywood outside, you can achieve the effect of insulation;2, insulation brick, mainly brick, it can be directly wall masonry, wall completed, the insulation effect is reflected.
Q:Can activated carbon be antiseptic?
In addition to activated carbon carbon, also contains two kinds of admixtures: one is the combination of chemical elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as the use of water vapor when activated, the surface of the active carbon is oxidized or water vapor oxidation; another kind of admixture is ash, it is part of the inorganic carbon in ash; activated carbon is easy to cause two pollution.
Q:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
In fact, brick and tile production is only a different production, the quality of brick produced is the same, from the silver horse experience
Q:How to reinforce a porous brick foundation?
The basic type method is changed from independent basis to strip foundation, from strip foundation to raft foundation and pile foundation, from brick to concrete strip foundation.
Q:How much is a thermal brick
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:Are there any differences between insulating bricks and refractory bricks
The degree of refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. 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:Masonry method for boiler refractory brick
Ash bucket (including inclined wall masonry):(1) and an ash bucket masonry first according to drawing find horizontal center line, with the horizontal center line to find out the ash bucket longitudinal center line, coarse slag bucket at the outside edge of the straight wall before and after, based on both ends of the facade vertical center line to pop up the bottom of the ash bucket, ash bucket with bottom opening size of pillar, pop-up vertical auxiliary line using triangle pattern production (according to the drawings, the inclination of inclined wall making) inclined wall paintings in the ends of the facade of the sideline. Use the same material to make refractory concrete inclined wall bottom of the triangle from Taiwan (Figure 1) and straight wall leveling, vertical and horizontal, inclined wall at the junction of the triangle from Taiwan, with the same material refractory concrete filling, until the final setting of concrete masonry wall inclined rear can.(2) and an ash bucket masonry masonry masonry, the first transverse longitudinal component after; inclined wall and straight wall, first built after the straight wall masonry wall.(3), on the back of a foundation by inclined wall, brick and mortar foundation contact surface to be full; inclined wall on the back fill cinder, corresponding to the 2~3 layer of brick masonry masonry, each high, fill a cinder cinder, must reinforce.
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: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.
