Ceramic Fiber for High Temperature Insulation
Descriptions of ceramic fiber for high temperature insulation:
Ceramic fiber blanket resists temperature as high as 1350C. This material is lightweight and has very low thermal conductivity, excellent handling strength, low heat storage, thermal shock resistance and corrosion resistance(commonly used acid and alkali). It also provides excellent sound absorption and excellent fire protection.
Advantages of ceramic fiber for high temperature insulation:
Excellent thermal and chemical stability | |
Good tensile strength, sound-absorbing | |
Low thermal conductivity, low thermal capacity | |
Easy to processed and installed for the second time | |
Anticorrosion, antioxidant, thermal shock resistance and so on | |
Good elasticity and low shrink in high-temperature |

- Q:What's the requirements of fire-fighting criteria of heat insulating material?
- Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
- Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
- The ceramics and refractories are different with the porcelain ceramic with high temperature of 1300℃ as household porcelain refractory. The porcelain refractory material of 1450℃ as the same as the aluminum oxide, kaolin, refractory clay and other raw materials demand the deployment ratio of the raw material the same as the temperature.
- Q:What's the fire endurance of hollow brick?
- This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980 ℃ is ok in reality. It depends on how thick your wall is because fire endurance of hollow brick is related to wall thickness. 24 wall can generally endure for 3 hours or more.
- Q:what's the varieties of thermal insulation material with A level fire?rating?
- Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.
- Q:What are some of the new refractories and what are their characteristics?
- These refractory materials can be bought in Zhengzhou real gold refractory materials factory. If necessary, we can visit the factory in Xinmi first.
- Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
- First, the cotton fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Rock wool board exterior insulation system, low thermal conductivity, good ventilation, combustion performance advantages of higher levels can be used in new construction, expansion, renovation of residential buildings and public buildings energy-saving exterior wall insulation works, including exterior insulation, fire Barrier non-transparent wall insulation and EPS external thermal insulation system. The introduction of main level A fireproofing EIFS on the present market (The following text is selected from China Building Standard Design and Research Institute " external wall thermal insulation building construction" Standard No. 10J121) Second, the foam concrete fire barrier zone 1. It is very green without the release of irritant and harmful gases; no mineral cotton floats do harm to human skin and the respiratory tract; production of?toxic?gases is security level (AQ1), there is no harmful gas and waste emissions and less carbon emissions; it exist not duplicate insulation demolition waste to pollute the environment.
- Q:How to apply the alumina powder on refractories?
- The most common one in use is the refractory bricks.
- Q:What are the models of refractory cables?
- NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
- Q:What refractories are used in various parts of the blast furnace.
- Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
- Q:What substitutes are available for high-end refractories in addition to zircon sand?
- The composite sand powder can effectively replace zircon sand, with the same operation process, less operation time and environmental protection
