Q:What is the feature of ceramic fiber washer?
1) Continuous use temperature can reach 1000℃ while short time using temperature is up to 1260℃. 2) It is highly resistant to acid-base corrosion and erosion of molten metal (eg. aluminum and zinc). 3).It is good in high temperature strength and thermal insulation properties (please refer to physical and chemical indicators.) 4) It is better in electricity insulation than glass fiber. 5) It is non-toxic, harmless and odourless.
Q:What is ceramic fiber blanket?
What brand of blanket doesn’t matter, the key is how to put it. If the whole sitting room is blanketed, it is recommended that the decorative pattern of carpet should be plainer. If it is laid under the sofa, you are advised to use color blanket. Considering which way to choose, firstly, it should unify the overall decoration style. Next, it should be easy to clean.
Q:Who can introduce how to use ceramic fiber binder?
1、It can be directly used with water, and it requires little maintenance with quality assured. The bonding strength is 3.5 times of concrete. 2、Tooth shape method is applied to bond thin layers with a little binder. And the binder is only 4-6mm in order to avoid hollowing tiles. 3、It is easy for workers to operate, greatly increasing efficiency of tiling. And it is very waterproof and resistant to moisture and seepage. 4、It is soft so that it won’t press tiles or cause cracks. It can stand thermocycling without detaching from base. 5、There is no need to soak tiles in water in advance and get walls wet, which can reduce working process and improve efficiency. 6、On the construction site, workers can finish the ratio of binder in accordance with proportion just in bucket, which is clean as well as efficient, and also reduces dust on building site.
Q:Who can tell me what the ceramic fiber density is?
Refractory ceramic fiber material, a kind of light and efficient thermal insulation material, owns the following advantages compared with traditional thermal insulating material: Ceramic fiber lining has low volume density. It is over 75%lighter than the light weight insulating brick, and 90%-95% lighter than the light weight castable lining. If fiber lining is used, the steel structure load of furnaces can be greatly reduced and its service life will be prolonged. Ceramic fiber lining has low thermal capacity which is only about l/10 of that of the light weight and heat resistant lining and light weight castable lining. The thermal capacity of the lining material is proportional to its mass. Low thermal capacity means that furnaces absorb less heat in the reciprocating operation, meanwhile accelerate its temperature rise, greatly reducing energy consumption during the operation and control of the furnace temperature, and particularly making the starting-up and blowing-out of heating furnaces obtain remarkable energy conservation effect. Ceramic fiber lining has low thermal conductivity. When the average temperature is 400℃, its thermal conductivity coefficient is less than 0.1w/mk; when the average temperature is 600℃, its thermal conductivity coefficient is less than 0.15w/mk; when it is 1000℃, the thermal conductivity coefficient is less than 0.25w/mk, which is around l/8 of that of the light clay brick and l/10 of that of the lightweight and heat resistant lining, achieving excellent thermal insulation effect. Ceramic fiber lining has easy construction. Expansion joints are not needed during the construction process, construction personnel can take up work right after basic training, and the construction technical factors have little impact on the lining’s thermal insulation performance.
Q:Who can tell me what ceramic fiber blanket is?
Ceramic fiber is a kind of fibrous lightweight refractory material with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical shock resistance and other advantages, so it is widely applied in industries such as machinery, metallurgy, chemical engineering, petroleum, ceramics, glass and electronics.
Q:How to keep ceramic fiber board?
There is no need to preserve. Products of ceramic fiber, made by using ceramic fiber as material, refers to industrial products with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical shock resistance and other advantages. It is exclusively applied in all kinds of high temperature, high pressure and environments where it is easy to wear.
Q:What is the material of ceramic fiber?
1、Ceramic fiber, ceramic fiber felt for short, is a fireproof material (such as flint clay) owing to resistance to high temperature. The fibrous substance, formed from being melt by electric arc and then blew up by compressed air, is called as ceramic fiber cotton. 2、Ceramic fiber cotton can be made into a variety of ceramic fiber products. The ceramic fiber cotton content of domestic ceramic fiber felt AI2O3 is 62% and 45%. The former one can be used in the temperature of 1150-2000℃ while the latter is in 1000℃.
Q:What's the function of ceramic fiber rope?
It can be used in heat insulation and preservation of all kinds of furnaces, high temperature pipes and containers; the sealing of furnace doors, valves and flanges, the fireproof door and fireproof shutter materials, high temperature furnace door curtains; heat insulation of engine and meter, fireproof cable coated materials, high temperature fireproof materials, heat insulation covering cloth, the high temperature expansion joint filler, flue lining; high temperature resistant labor insurance products, fire-proof suit, high temperature filtration, sound-absorbing and other fields of replacing asbestos.
Q:What are the ceramic fiber products?
Ceramic fiber is produced by double needling technique and is widely used in high and low temperature environment. According to the different manufacturing technique used in market, ceramic fiber blanket is usually divided into two kinds. One is thread throwing blanket, and the other is injection fiber. 1. The diameter of the fiber filaments: Thread throwing fiber is much coarser. Thread throwing fiber is generally 3.0-5.0;micro;m; Injection fiber is generally 2.0-3.0;micro;ml. 2. Fiber length: Thread throwing fiber is much longer. Thread throwing fiber is generally 150-250mm. Injection fiber is generally 100-200mm. 3. Coefficient of thermal conductivity: Injection blanket is superior to thread throwing blanket because of its thin fiber. 4. Tensile and flexural strength: Thread throwing blanket is superior to injection blanket because of its coarse fiber. 5. Application of making ceramic fiber block: It is superior to injection blanket because the fiber of thread throwing blanket is much coarser and longer. Injection fiber blanket is easy to be broken and torn during the process of block production folding, while thread throwing fiber blanket can be tightly folded and cannot be easy to damage. The quality of the block will directly affect the quality of the lining. 6. The vertical layer spread application of large pieces of blankets such as heat recovery boiler: Thread throwing blanket has better tensile resistance and is more durable due to its coarse and long fiber filament, so thread throwing blanket is superior to injection blanket.
Q:What’s the difference between the ceramic fiber and glass fiber?
Ceramic fiber strip, a type of fibrous lightweight refractory, possesses so many advantages as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical shock resistance. Therefore it has been widely applied in machinery, metallurgy, chemical engineering, petroleum, porcelain, glass, electronics, and other industries. As a sort of refractory material, ceramic fiber strip is made out of highly purified refractory fiber, and applied in high temperature and thermal insulation field. Compared with natural cellulosic fiber, the raw material of glass fiber tape has the following features: with circular section and the same diameter, glass fiber can be micro fine. It’s higher in specific gravity and more stable in dimension. As a result, the paper made from it by papermaking gains fairly high tensile strength, and excellent properties of water-fast, oil resistance, acid and alkali resistance, corrosion resistance, thermal stability, low thermal conductivity, sound absorption, etc.
