断熱耐火レンガ
The raw materials for insulating lightweight refractory bricks can be classified as clay, ケイ素, アルミニウム, ムライト. 軽量レンガは気孔が多いため断熱性に優れています (クローズとオープンの両方). 多孔性を引き起こす方法には、可燃物の添加が含まれます, 泡, と化学物質. 軽量耐火れんがは圧縮強度が低い, 耐スラグ性が悪い, poor heat, and vibration resistance, ガラスの液体や炎と直接接触することはできません.
PER insulated refractory bricks are a high-quality insulation material for a wide range of kilns. The insulation bricks we produce have many excellent properties such as lightweight, 優れた耐熱衝撃性, 高温耐性, thermal energy saving, 熱伝導率が低い.
PER has various kinds of insulation bricks for sale, such as mullite insulation bricks, 粘土絶縁レンガ, high alumina lightweight insulation bricks, silica insulation bricks, alumina bubble bricks, その他の製品.
PER Insulation Brick Types
Silica Clay Light Insulation Brick
Silica clay light insulation brick is made of high-quality silica clay, wood layer, and high-temperature binder as the main raw material, which is mixed, squeezed and shaped, 乾燥した, and then prepared.
Because the product contains many microporous, it has the advantages of high compressive strength, かさ密度が低い, small thermal conductivity, 軽量, safe and convenient construction, good heat preservation and energy saving effect, and good quality and price compared with clay, 高アルミナ, bleaching beads and fiber off heat products.
Light Weight Mullite Insulation Brick
Light weight mullite insulation brick light weight come stone insulation have average, thermal shock characterization good, load chemical high, high cross value small, degree large, resistance to chemical word note good and other characteristics.
Mullite light insulation brick is mainly divided into light and heavy according to the difference of density.
アルミナバブルブリック
Alumina bubble bricks is a new type of high-temperature insulation material, 温度の利用 1800 ℃, the product version of high strength, for the service of light products several times, while the volume degree is only one-half of corundum products.
Generally used in petrochemical industry gasification furnaces, carbon black industry reaction furnaces, cure all industry induction furnaces, and other high-temperature furnaces.
High-Alumina Poly-Light Brick
High alumina poly light brick is a new type of heat insulation of light high alumina brick series, mainly using high alumina and high purity withered earth, filled with polyphenylene froth ball, by burning out into the period.
It has the characteristics of high purity of raw materials, average pore structure, 熱伝導率が低い, low heat capacity, 高強度, and high dimensional accuracy.
High-light brick is also called high alumina poly light ball brick, with high-pressure strength, and good thermal stability that can reduce the heat capacity of the furnace.
The Difference Between Insulation Brick and Refractory Brick
The main role of insulation bricks is used for heat preservation, to reduce heat loss, insulation bricks generally do not directly contact the flame, while refractory bricks generally directly contact the flame.
Insulation Brick and Refractory Brick's Main Differences are as Follows
1. Thermal Insulation Performance
Insulation brick thermal conductivity is generally in 0.2-0.4 (average temperature 350 ± 25 ℃) w / m.k, while the thermal conductivity of refractory bricks in 1.0 (average temperature 350 ± 25 ℃) w / m.k above, it can be concluded that the insulation performance of the insulation brick than the insulation performance of refractory bricks is much better.
2. 耐火物
The refractories of insulation brick are mostly below 1400 度, while the refractories of a refractory brick are above 1400 度.
3. Density
Insulation bricks are mostly light insulation materials, density is mostly 0.8-1.0g/cm3, while the thickness of refractory bricks is basically 2.0g/cm3 or more.
The Advantages Of Insulation Bricks And Refractory Bricks
Comprehensive, the advantages of refractory bricks are high mechanical strength, long service life, good chemical stability, no chemical reaction with the material, and good high-temperature resistance, the highest heat-resistant temperature can reach 1900 ℃. It is especially suitable for use in high and low-temperature conversion furnaces, conversion furnaces, hydrogenation converters, desulfurization tanks, and methanation furnaces in fertilizer plants to disperse gas and liquid and to support, cover and protect catalysts. It can also be used in hot blast furnaces and heating and converting equipment in the steel industry.
The advantage of insulating brick is a new building energy-saving insulation technology with inorganic composite materials as the main raw material, which is an ideal technology to replace the traditional external wall insulation. Insulation brick in the masonry wall at the same time will be an excellent insulation effect on the wall.
Refractory brick and insulation brick are very different, their use of the environment, scope, and role are different. Different locations will use different materials, in the purchase of materials, it is recommended to determine the appropriate refractory materials according to the actual situation of the enterprise itself.
