Q:What is the difference between the national standards for ceramic fiber products and ordinary aluminium silicate?
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 ceramic fiber products (aluminium silicate fiber products) is 22 - 33 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 ceramic fiber products (aluminum silicate fiber products) is more important. The range of Al2O3SiO2 fiber contraction in various products of 1260 C line is 35 - 88%. The amount of shrinkage is also directly related to thermal stability. Ceramic fiber products (aluminum silicate fiber products) as ceramic fiber products (aluminum silicate fiber products) with low thermal conductivity, low density, light weight, light steel frame are used in the design and construction of kilns supporting structure, so that the development of ceramic kiln kiln into the "lightweight" era. The fiber has small heat storage and is suitable for quick heating and cooling firing.
Q:ceramic fiber
Advantages of ceramic fiberRefractory ceramic fiber material is a lightweight and efficient thermal insulation material. It has the following advantages over traditional heat insulation materials:Ceramic fiber as lining, low volume density: ceramic fiber lining than light heat insulation brick lining light more than 75%, lighter than light castable lining light 90% to 95%. If using fiber lining, it can greatly reduce the steel structure load and prolong the service life of the furnace.The heat capacity (heat storage capacity) of ceramic fiber lining is low: the heat capacity of ceramic fiber is only about l/10 of light heat resistant lining and light castable lining, and the heat capacity of lining material is proportional to the weight of lining. Low heat capacity means the furnace in the reciprocating operation absorb less heat and heating speed, greatly reducing the operational control of the temperature in energy consumption, especially for heating furnace and furnace, furnace shutdown has obvious energy saving effect.Ceramic fiber lining: low thermal conductivity of ceramic fiber lining in the average temperature of 400 degrees, the thermal conductivity is less than 0.1w/mk, the average 600 degrees less than 0.l5 w/mk, average 1000 degrees less than 0.25w/mk, about l/8 as a lightweight clay brick, lightweight refractory lining l/10, adiabatic effect.The construction of ceramic fiber lining is simple: no expansion joints are needed during construction, and the construction personnel can be started after the basic training. The technical factors of construction have little influence on the insulation effect of the lining. Ji'nan Sheng Yang
Q:What kind of material is ceramic fiber? What are the basic performance?
(2) the density of Tao Xianzhan is below 200Kg/m3 (generally 160kg / m3), only light heat resistant lining L / 6 - 1/7.(3) the heat capacity is only 1 / 9 of light heat resistant lining and light fireclay bricks.(4) the ceramic fiber is stable in high temperature, the residual shrinkage rate is very small, and it needs no shrinkage or expansion joints, so it is easy to construct.(5) the coefficient of thermal conductivity is small. On the hot surface temperature of 600 degrees Celsius (the average temperature of 366 DEG C) when the orientation coefficient is 0.078W / (M. K); 900 (the average temperature is 551 DEG C) of O.096W / (m.k); 1100 (the average temperature is 678 DEG C) of 0.125W / (m.k), is about light fireclay bricks 1 / 8, for the light at 1 / 10 heat resistant lining.(6) sound insulation effect is good. The ceramic fiber coating can reduce the high-frequency noise with frequency less than 1000Hz, and also absorb some low-frequency noise.(7) it has a certain tensile strength.(8) good chemical stability.(9) good elasticity (78% at normal temperature), easy to transport and install.(10) it has better resistance to airflow erosion, and can withstand 30 - 50m/s airflow erosion.
Q:The characteristics of ceramic fiber paper
Ceramic fiber paper, aluminum silicate fiber paper, also called refractory fiber paper.Classification of ceramic fiber paper:Standard ceramic fiber paper HLGX-236High alumina ceramic fiber paper HLGX-436Ceramic fiber paper containing zirconium HLGX-536
Q:Can a series of ceramic fiber products be used in combination?
High temperature pipe external insulation: (power plant, petrochemical, municipal and other high temperature pipeline)Materials required: ceramic fiber blanket, ceramic fiber cloth / rubberized fabric, ceramic fiber yarn
Q:Slag ball content of ceramic fiber material?
Effect of slag ball content on ceramic fiber materialSlag ball content ceramic fiber products is an important factor that affects the bulk density. Slag ball density in 2800 ~ 3200kg/m fand, excessive slag ball content fiber products, comprehensive energy-saving performance will reduce the ceramic fiber blanket, ceramic fiber module of ceramic fiber products, and damage the interests of users.
Q:What is the use of ceramic fiber paper?
Mifso-14 ceramic fiber paper gasket is Xin Xing sealing material factory is composed of ceramic fiber products through precise cutting, punching, die stamping process (part of the product after ultra high pressure adhesive bonding) produced. Can be customized by users to produce sizes.
Q:Definition of ceramic fiber
The utility model has the advantages of light weight, high temperature resistance, small heat capacity, good insulation and heat insulation performance, good high-temperature heat insulation performance, no toxicity, etc..So far, Chinese domestic ceramic fiber manufacturers now have a total of more than 200 large and small, but the temperature is 1425 DEG C (zirconium containing fiber) production process and the following ceramic fibers, were divided into left and blowing two carpet carpet.
Q:The product characteristics of ceramic fiber cloth?
Product characteristics:High temperature resistance, low thermal conductivity, thermal shock resistance and low heat capacity;
Q:What is the customs code for ceramic fiber products?
The customs code should be 6914.9000Specific can be seen by the Chinese customs published in 2005 edition of import and export commodity names and codes, thirteenth and sixty-ninth chapters, ceramic products, P166-168 pages.
