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 project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
From the structure principle, hydropower shaft with solid brick, is to consider the safety performance of the structure.
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 is the price of fireproof insulation material?
Fire insulation materials are various, different specifications, grades of prices are different, according to market rules, there will be fluctuation, the most commonly used are insulation rock wool, insulation board, insulation bricks, fire blocking materials.
Q:Are there any construction waste materials for composite thermal insulation bricks?
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:What is composite sintering insulation bricks?
The brick belongs to the porous brick and has good heat preservation performance. Reached the national 50%~65% energy efficiency standards. High safety (no crack, no seepage), strong durability (with building life), economy (self insulation, no need to increase the cost of insulation).
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
Not the same thing, refractory bricks and insulation bricks of raw materials, the proportion is not the same. This is the chain of various types of products
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, durable, lightweight, simple construction, easy handling, economy, green environmental protection, sound insulation, fire protection etc..
Q:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
The original "technical specification for self insulation masonry building with silt insulation bricks" has been replaced by DGJ32/TJ78-2009 (technical specification for automatic insulation wall system of sintered silt non bearing insulating brick) DGJ32/TJ78-2013.
Q:Are there any differences between insulating bricks and refractory bricks
Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
