The ceramic fiber are manufactured from high purity raw material alumina powder ,silica sand for the high temperature grades and zircon sand is also used. The ceramic mixture is heated in an high temperature electric furnace and the stream of molten material is drawn into fibers by either spinning or blowing .It is produced by advanced “blown” and “spun” processes .Ceramic fiber bulk shows a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to oxidation and reduction
Excellent thermal and chemical stability
Low thermal conductivity and heat storage
Excellent thermal shock resistance and sound –absorption capability
No bonding agent and corrosive substance
Asbestos free

- Q: What are the materials for making ceramic fibers?
- In recent years, because of the global energy prices continue to rise, energy saving has become a China national strategy background, than the insulation bricks and other traditional refractory pouring material such as 10-30% ceramic fiber has been more and more widely used in the domestic Chinese, development prospect is very promising. Throw carpet and spray carpet difference
- Q: What's the fire resistance of the ceramic fiber?
- The most important index of porcelain refractory fiber is the diameter and thermal stability of the fiber. Al2O3SiO2 fiber is commonly used in ceramic industry. It is divided into different application range according to the content of Al2O3, and Cr2O3 material is introduced into it to improve its refractory and oxidation resistance. Generally high alumina content, iron oxide and other impurities of low fiber products are pure white, the introduction of chromium oxide fiber is sold with milk yellow tone color. The average diameter of the ceramic fiber is 24 microns. High fiber, small density, low thermal conductivity, high temperature. If the fiber is coarse and dense, the use is not satisfactory. The thermal stability index of fiber is more important. Al2O3-SiO2 fiber products range between 1260 and 3588% in line shrinkage. The amount of shrinkage is also directly related to thermal stability.
- Q: Is everybody ceramic fiber cotton poisonous?
- No poison, carpet fiber silk if coarse, there is a little prick, make the skin may itch.
- Q: Which insulation effect is better compared with ceramic fiber for STP insulation board?
- Solid energy saving STP insulation board, its insulation performance than traditional ceramic fiber insulation material is better than 3~4 times
- Q: Can ceramic fibers be spun into fibers, please?
- Ceramic fiber itself is relatively brittle, silk is relatively short, spinnability, but after adding viscose (differential polyester glass fiber, even pulp) as the heart can be spun
- Q: Why is there no direct relationship between thermal conductivity and conductivity of ceramics?
- The concept of electrical conductivity in physics, in which the product of the quantity and the electric field intensity is equal to the conduction current density. For isotropic media, conductivity is scalar; for anisotropic media, conductivity is tensor. In ecology, conductivity is the ability to conduct current by means of a numerically expressed solution. The unit is expressed in SIEMENS per meter (S/m). The conductivity is simply the product of the measured conductivity (G) and the conductance cell constant (L/A). Here the L is the length of the liquid column between two plates and the A is the area of the plate. P l=l/ = sigma (1) definition or explanation for the reciprocal of resistivity conductivity. Sigma Rho =1/ (2): units in the international system of units, the conductivity of the unit is SIEMENS / m. (3) the physical meaning of conductivity is to indicate the conductivity of a substance.
- Q: What is the essential difference between the standard of ceramic fiber and ordinary aluminium silicate?
- Ceramic fiber products (aluminum silicate fiber products) in recent years, ceramic fiber products (aluminum silicate fiber products) in the application of high temperature sintering furnace expanding, ceramic fiber products (aluminum silicate fiber products) refractory felt and blanket products, the highest use temperature up to 1649 DEG C. Ceramic fiber products (aluminum silicate fiber products) to heat insulation effect is good, easy to use, especially small heat storage characteristics, widely used in various kilns, greatly demonstrated high energy efficiency.
- Q: Do fiberglass or ceramic fiber paper have insulation effect?
- Second, in the case of temperature can be met, glass fiber cotton insulation better. The main advantage of ceramic fiber is to make gaskets and the like.
- Q: Why doesn't the insulation effect of ceramic fiber compound reflect the insulation board well?
- Tianjin solid composite reflective insulation board, he has one of the biggest advantages of long-term high temperature, the use of chemical stability, and can be used for a long time.
- Q: What's the function of refractory ceramic fiber band?
- Refractory ceramic fibre belt is made of ceramic fiber cotton, E-glass filament, high temperature resistant stainless steel alloy wire processed by special technology, products of high strength, good flexibility, high machinability, not only has high temperature heat insulation performance, both ordinary textile flexibility.
