Q:Ceramic fiber blanket and ceramic fiber blanket rejection blowing spray what difference
The same kind of resistance to temperature is the same. In the aspect of shrinkage, the spinning is stronger than the blowing. Imagine cotton. The fibers are long and the fibers are short. Wire rejection is recommended.
Q:What’s the maximum bearing temperature of the refractory and high temperature resistant ceramic fiber cotton?
It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
Q:What's the function of ceramic fiber rope?
It can be widely applied in industries such as chemical engineering, electric power, papermaking, food, pharmacy, etc. and the sealing of boiler door, machine, pump and valve with high temperature and high pressure. It is suitable for medium such as clean liquid or slurry, salt water, emulsion, grease, hydrocarbon, solvent, pulp, etc.
Q:What’s the difference between heat preservation and heat insulation ceramic fiber blanket and rock wool blanket?
The difference between heat preservation and heat insulation ceramic fiber blanket and rock wool blanket: refractory ceramic fiber material is a kind of lightweight and efficient heat preservation and heat insulation material. Its advantages are as follows: the volume and density of ceramic fiber as lining are low. Ceramic fiber lining is 75% lighter than lightweight insulating brick lining and 90%-95% lighter than lightweight castable lining. If fiber lining is adopted, steel structure load of furnace can be greatly reduced and the service life of the furnace can be prolonged. Heat capacity (heat storage) of ceramic fiber as lining is low: Heat capacity of ceramic fiber is about 1/10 that of lightweight and heat resistant lining and lightweight castable lining. Heat capacity of furnace lining material is proportional to the weight of the furnace lining. Low thermal capacity means that furnace absorbs less heat in the reciprocating operation and, at the same time, the speed of warming gets faster, which greatly reduces the energy consumption of the furnace temperature operation and control and especially plays a very significant role in energy saving effect in the starting-up and blowing-out of heating furnace. Thermal conductivity of ceramic fiber as lining is low: When the average temperature is 400℃, 600℃ and 1000℃, thermal conductivity coefficient of ceramic fiber as lining is less than 0.1w/mk, 0.15w/mk and 0.25w/mk respectively, which is 1/8 that of lightweight fireclay brick and 1/10 that of lightweight and heat resistant lining. Ceramic fiber as lining has prominent insulation performance. Ceramic fiber as lining is easy to construct: Expansion gap is not needed during the construction process. Construction personnel can start to work after basic training and construction technology has little effect on the heat insulation effect of lining.
Q:What are the specifications and models of the ceramic fiber board?
In terms of the characteristics of the ceramic fiber board, it has high compression strength and long service life, low thermal capacity and heat conductivity, non-brittle material quality and good toughness, accurate dimension and good flatness, easy cutting and installation, and good anti-wind erosion properties. With continuous production and uniform distribution of fibers, it has stable performance and fine sound absorption and noise reduction properties.
Q:What’s the density of ceramic fiber board?
The density of ceramic fiber board is 280-320kg/m3. Made by adopting wet process and vacuum forming techniques, the ceramic fiber board is higher in strength than the fiber blanket and vacuum forming felt, and it applies to high temperature fields with requirement on rigidity and strength of products. The ceramic fiber board has high compression strength and long service life, low thermal capacity and heat conductivity, non-brittle material quality and good toughness, accurate dimension and good flatness, easy cutting and installation, and good anti-wind erosion properties. With continuous production and uniform distribution of fibers, it has stable performance and fine sound absorption and noise reduction properties.
Q:Who can introduce how to use ceramic fiber binder?
1、 Pour tile cementing agent into water and stir it into paste (mixing ratio: 20 kg powder+6 kg water). After stirring, place it about 10 minutes, and then stir it slightly, finally it can be used, which is helpful to fortify binding force. 2、Paint cementing agent onto the working surface with tooth-shaped scraper to assure it is distributed evenly in tooth shape. 3、Press tiles onto it in the open assembly time.
Q:What is the difference between a ceramic fiber shell or an aluminum silicate tube shell?
Ceramic fiber shell and aluminum silicate tube shell is actually the same kind of thing, just name different. Belong to the family of Portland, ceramic fiber tube and shell is a professional name, aluminum silicate segment is referred to as.
Q:Is ceramic fiber cotton block poisonous?
The dust produced by ceramic fiber cotton block is harmful to body, mainly presented as respiratory symptom, skin and eye irritation symptom, lung function reduction, obvious change of chest radiograph abnormities.
Q:What is the performance of ceramic fiber tube furnace?
The performance of ceramic fiber tube furnace is fairly good and its raw material is ceramic fiber. Ceramic fiber is a fibrous and light fireproof material with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., thus being widely used in such industries as machinery, metallurgy, chemical industry, petroleum, ship, electronics and light industry. And it becomes increasingly widely used in top science and technology departments, like aviation and atomic energy, and full of development prospect.
