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:There are several construction techniques for exterior wall insulation
Exterior wall sandwich insulation technologyThe exterior wall sandwich insulation is to place the heat preservation material between the inner and outer wall sheets of the outer wall, and the inner and outer walls can be made of concrete hollow blocks.Advantage:1) to the inner wall piece and the heat preservation material forms the effective protection, to the heat preservation material selection material request is not high (source: Chinese heat preservation net), polystyrene, glass cotton and urea aldehyde field casting material and so on may use;2) the construction season and construction conditions are not very high, and it does not affect the winter construction. In Heilongjiang, Inner Mongolia, northern Gansu and other cold areas have been given some applications.Shortcoming:1) in non cold areas, this kind of wall is thicker than traditional wall;2) the inner and the outer wall pieces need to be connected by connecting pieces, and the structure is more complicated than the traditional wall;3) periphery structure of "bridge" more. In the earthquake zone, building circle beam and constructional column settings, "bridge" more efficiency of thermal insulation materials is still not fully play.4) outside the walls by the outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking and leakage of rainwater.
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:What are the bubble bricks?
The steam free aerated block has the advantages of wide raw material sources, high waste rate and low cost. With fly ash, slag, sand, sand, soil containing low amount of powder and tailings as the main raw materials (with one can), local materials, low cost, high profit.
Q:What are the improvements and improvements during the trial production of insulating bricks?
Insulation brick seven characteristics: insulation, heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.
Q:What is mullite insulation brick?
Main features of mullite insulating bricks:1., green environmental protection, non-toxic, non corrosive, safe to use.2. 、 good adaptability with cement.3., light insulation brick with foam mechanism bubble, can get foam uniform bubble diameter.4. excellent foaming performance, foaming multiples of more than thirty times.
Q:What bricks are thermal insulation bricks?
Insulating bricks, a new type of product that can replace tiles, are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:Advantages and disadvantages of wall insulation system?
The advantages of internal insulation: insulation walls, paint inside the wall, and direct people or other biological contact, in order to ensure human or biological health in insulation coating insulation at the same time, we must first ensure that the paint is non-toxic, no volatile substances.
Q:Is the building built of cement hollow board safe?
The country stipulates that hollow slab buildings can be built at most 7 floors, and of course there are also eleven stories, but these are illegal constructions. More than 7 layers, in the existing architectural design, according to the cement hollow board bearing, there is a security risk;
Q:What is the bulk density of the sintered bricks?
The Dragon such high aluminum refractory brick density is generally around 1000, heavy refractory brick, high alumina brick HLGX heavy weight in general 2000Kg/m fand.
Q:Is sintering insulation brick good or concrete porous brick good?
As with the expansion screw, it depends on what to connect, and go in is no problem, the key is that the carrying capacity is not very high, if you do steel support, pull and so on, it is recommended to use concrete.
