What are the use fields of ceramic fiber board?

Ceramic fiber board is more extensive in application, which is understandable fact, and what are the use fields of ceramic fiber board?

1. Light industry: industrial and household boiler combustor lining.

2. Building material industry: cement rotary kiln and other equipment insulation.

3. The ceramic industry: light kiln car structure and the furnace's hot surface lining, the furnace's temperature separation and fire material.

4. The glass industry: the molten pool back insulation, burner block.

5. Furnace construction: hot surface refractory material (alternative fiber blanket), heavy refractory material back lining, expansion joints.

6. The steel industry: expansion joints, back lining insulation, heat insulation piece and mold insulation.

The main composition of refractory material

The mineral composition of refractory brick is mainly kaolinite (Al2O3 · 2SiO2 · 2H2O) and 6% ~ 7% impurities (potassium, sodium, calcium, titanium, iron oxide). Select the high density, low water absorption of raw material, a reasonable level of preparation is the key to make low porosity refractory brick. Refractory brick is made with 50% soft clay and 50% hard clay clinker according to certain granularity requirements. After molding and drying,  firing under high temperature of 1300 ~ 1400 ℃.

The firing process is mainly due to the process of crystallization of mullite (3Al2O3 · 2SiO2). The SiO2 and Al2O3 in the refractory brick form a eutectic and low melting point silicate with the impurity during the firing process, surrounded by mullite crystals. The maximum temperature in the firing process is usually controlled at 1350 ° C to 1380 ° C, and the firing temperature of the low porosity fire clay brick (1420 ° C) is increased. The shrinkage of refractory brick is slightly increased, so that the density of ceramic fiber board increases slightly and the low porosity is decline.

Refractory brick do not use the same kind of mud to use different appliances, fire mud selection of cleaning water, accurate weighing modulation, uniform mixing, tune the mud can not be arbitrarily diluted with water, mortar fullness is greater than 95% or more, ensure solid brick joints, the surface brick seam jointing with virgin pulp, the shell can not correct the parts with mud.

Refractory brick has a certain shape and scale of refractory material, large unit volume weight, large density, indicating that the density is good, the strength may be high, also known as high temperature load deformation temperature, called the burner change or called the residual line change.

The Performances of Fire Clay Insulation Brick

The performances of fire clay insulation brick is as follows:

1. Low thermal conductivity, with a good thermal insulation effect.

2. Low heat melting, due to low thermal conductivity.

3. Low impurity content, with very low iron content such as alkali metal and so on. Therefore, refractoriness is high. Higher aluminum content still maintains good performance in the reduction atmosphere.

4. High thermal compressive strength.

5. The appearance size is accurate, speed up the masonry speed, reduce the use of refractory mud, in order to ensure the strength and stability of the masonry, thereby extending the life of the lining.

6. Can be processed into a special shape. In order to reduce the number of bricklayers and joints.

How to identify the quality of corundum brick in the market

Corundum brick has a good chemical stability, acidic or alkaline slag, metal and glass, etc. have a strong resistance, but now the market in the production of many enterprises, so we also have a lot of choice in the main issues, This requires us to have the ability to identify the quality of corundum brick in order to buy high-quality products.(http://www.corundumbrick.net/product/corundum_block.html)
The corundum brick in the market is mainly composed of corundum, corundum has a high corrosion resistance and high temperature characteristics, it is an important refractory brick, widely used in refractory production and processing. Smelting rare precious metals, special alloys, ceramics, iron ore blast furnace lining, another corundum also has a high hardness, good wear resistance, high strength characteristics, can be used in the production of various molds, knives, corundum brick can also made bulletproof material, corundum wear resistance can produce a variety of wear-resistant materials.
The corundum is divided into three grades: the first level of corundum, two and three, the quality of corundum mainly see its Al2o3, its content in the 94.5% -97%, and the other contains a small amount of Fe, Si, Ti Wait. Al2o3 content of more than 95% for the first grade corundum. Two corundum and three corundum content gradually reduced, the quality also will be reduced. Corundum fineness can look at the color to distinguish, because the corundum contains iron elements, iron elements for the reddish-brown, so brown corundum appears to be tan, you can see through the color of corundum brick grade and quality.

The Application of Mullite Insulation Brick is More and More Wide

In the early, mullite insulation brick is used as the main building insulation layer, or as a decorative and sound insulation, a new type of insulation material, compared to the previous clay red brick to use more convenient and better, with the technology The development of the times. Mullite insulation brick before the performance and characteristics have been far from our current requirements. And the application of insulation brick in various industries are more and more widely, we also need to manufacture and produce different properties of mullite insulation brick products.(http://www.insulatingbrick.com/product/mullite_insulation_brick.html)

And now mullite insulation brick products have been in a number of industries and areas of which a great victory in the insulation performance, strength, the weight is sufficient to meet our use requirements, but in the future we need to involve a lot , While we are in the heat insulation requirements for the standard is not only improve at the same time, also need to improve the other properties and characteristics, such as in the industrial furnace insulation which can not only save the furnace temperature, but also can save the furnace Coal gas consumption, reducing the production of waste of resources which also improve and protect the life of the furnace.
