Introduction
The external thermal insulation rockwool board is designed for the buildings of external thermal insulation system with thin finish coat and applys to external wall insulation and energy saving of new or existing building whose foundation wall is concrete or brick and other compact structures.
 
The external thermal insulation rockwool strip can also be used as fire barrier to improve the fire resistance of buildings external walls with other thermal insulation materials.    


Features and Application

1,High compressive strength, tensile strength and good durability ensures the reliability and long-term stability of the product in the application.
 
2,Low thermal conductivity can effectively reduce the heat loss of the building to achieve energy saving and emission reduction.
 
3,External thermal insulation rockwool boards will not release heat and poisonous smoke because of its incombustibility and can effectively partition the spread of flam when fire occurs.
 
4,It has good performance of non-hygroscopicity, ageing resistance and long-term stability.
 
5,It is light weight and easy to be cut and processed

Q:What are the features of ceramic fiber module?
Ceramic fiber, also called refractory fiber, is a refractory material with the lowest thermal conductivity and the best thermal insulation and energy-saving effect so far except nanometer materials. It is a good industrial furnace lining material with light weight, high heat resistance, good heat preservation effect, easy construction and other advantages. The high heat sensitive of ceramic fiber furnace lining can better adapt to the automatic control of heating furnace. The chemical performance of ceramic fiber lining is stable. Acid, alkali, as well as water, oil, steam are not eroded except phosphoric acid, hydrofluoric acid and strong alkali.
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 use of ceramic fiber rope?
Ceramic fiber rope is interweaved with quality ceramic fiber. It is widely used in chemical industry, electricity, paper-making, food, pharmacy, etc., as well as sealing of furnace door, high temperature &pressure engine, pump and valve. And it is applicable to various medium, such as clean fluid or slurry, saline water, emulsion, oil, hydrocarbon, solvent, paper pulp, etc.
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 price of refractory ceramic fiber blanket?
Ceramic fiber refractory thread throwing blanket is 4000 yuan per ton. Ceramic fiber refractory insulation module is 4700 yuan per ton. Ceramic fiber board refractory insulation board is 7000 yuan per ton. These are good.
Q:What’s the density of ceramic fiber board?
The density of fiberboard by wet molding process is 280-320kg/m3. The smaller one is called ceramic fiber felt in national standard, and its maximum density can be up to around 700 kg/m3.
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 use of ceramic fiber resistance furnace?
The series of box muffle maximum working temperature can be up to 1200℃, and it can be used in the field of laboratory rooms, industrial and mining enterprises, and research and development institutions for elemental analysis and determination, quenching, annealing, and tempering of the small-sized steel.
Q:How is the ceramic fiber cotton performance?
Ceramic fiber, integrating traditional thermal insulation materials with the excellent properties of refractory materials, is a kind of fibrous lightweight refractory material. Its product involves various fields and is widely used in various industrial departments. It is the basic material to improve the thermal performance of thermal equipment such as industrial furnace and heating device and achieve lightweight structure and energy saving. Performance and application: low thermal conductivity, good thermal stability and chemical stability, non-corrosiveness. Brake lining made by this fiber has good high temperature resistance and dispersion and is suitable for the mixing of all kinds of mixers. It is suitable for the brake lining with high temperature requirements, good heat recovery performance and small brake noise. 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. The application of it in cutting-edge science and technology departments such as aerospace and atomic energy is also increasing. It has a very prospective future. Ceramic fiber in our country starts late, but has always maintained a momentum of sustainable development with production capacity constantly increased and product serialization achieved.
Q:What is the raw material of 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 industry as machinery, metallurgy, chemical industry, petroleum, ceramic, glass, electronics, etc. Besides the good quality of fibrous ceramic fiber cotton, the product made out of ceramic fiber board is very hard and resistant to wind erosion. Ceramic fiber backing board is light, easy to work, and it won’t expand after being heated. It can be sheared and curved optionally. Thus, it is an ideal energy-conservation material for furnace, pipeline, and other thermal insulation equipment. The application of making ceramic fiber modules: Thread throwing blanket is better than injection blanket because of its thick and long fiber. In the folding process of making modules, injection fiber blanket is easy to break up and tear up while thread throwing fiber blanket can be folded tightly and not easy to break up. The quality of modules will directly affect the quality of furnace lining.
