Product Description:

CeramicLooseFiberis made by the melted raw materials at high temperature through resistance furnace, before being blown or spun into fiber. As a neutral and acidic material, except reaction with the strong acid-alkali,refractoryceramic fiber won’t be eroded by other weak alkali, weak acids, or water, oil, steam, or be infiltrated with lead, aluminum or copper, featuring excellent flexibility and elasticity. Ceramic fiber is of smaller density, more than 75% lighter than insulation brick lining or 90% -95% lighter than lightweight castable lining, with thermal conductivity co-efficient to be 1/8 of the lightweight clay brick or 1/10 of lightweight heat-resistant lining (castable), and heat capacity to be 1/10 of both lightweight insulation lining and lightweight castable lining, thus to greatly lower energy loss and deliver significant energy-saving regenerative effects. Meanwhile, the ceramic fiber features a simple construction with no need of baking oven, shortened construction cycle and easy installation.


Characteristics: 
Low heat capacity and low thermal conductivity;
Excellent chemical stability;
Excellent thermal stability, resistance to pulverization at high temperature;
With no binders or corrosive substances;
Excellent sound absorption

Typical Application: 
Raw material for fiber blanket, board products;

Q:Glass fiber cotton, aluminum silicate cotton, rock wool, what's the difference between these three?
Name: Cotton aluminosilicate ceramic fiber cotton, is an almost pure inorganic fiber, formed by blowing process production process or thrown silk spray, is a kind of low thermal conductivity, low heat capacity; high strength, high tear resistance, excellent machining performance. Aluminum silicate insulation material has become the best industrial furnace lining wall insulation materials, completely replace refractory bricks.
Q:Aluminum silicate needle carpet and ceramic fiber insulation performance of the good
Aluminum silicate needle carpet should be aluminum silicate needled blanket, with the continuous production, by acupuncture fiber uniformity, high tensile strength, does not contain any additives. Ceramic fiber, also known as aluminum silicate fiber, is only a different name.
Q:The difference between the ceramic fiber blanket and rock cotton blanket
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.
Q:What are the main differences between an ordinary furnace and a ceramic fiber furnace?
Service life: ordinary furnace quenching, sudden heat, easy to cause blasting chamber or cracking, shorten service life, ceramic fiber furnace without blasting chamber or crack possible.There are two common practices in ceramic fiber furnaces:The first is a larger furnace, which is fixed on the furnace wall with ceramic fiber modules;The second is a small furnace, the manufacture of abrasives, direct pouring, or with punch milling machine processing ceramic fiber board.
Q:What is the density of ceramic fiber modules? The best insulation effect?
Ceramic fiber module density in 200-220, the first production of ceramic fiber module is generally made of ceramic fiber blown blanket, fiber blown blanket fine short, ceramic fiber module is made out of the expansion is relatively stable, but in recent years because of the cost of production, the majority of ceramic fiber module are thrown silk do relatively, the tensile force is big, according to your own combustion atmosphere of furnace temperature and heating module and intracranial, select the density and thickness of the ceramic fiber module. Just make the insulation layer, then recommend 200kg/ cubic meters. Ring fire-resistant insulation materials company has a specific index and design analysis.
Q:Should the ceramic fiber furnace be compacted
In view of the miniature furnace chamber, the ceramic fiber furnace can be selected, and once the furnace is formed, the length of the furnace is longer.
Q:What is the good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?
Applicability: glass fiber (melting point 680 degrees) belongs to medium and low temperature insulation material, suitable temperature is below 700 degrees, aluminum silicate fiber belongs to high temperature insulation material, use fire temperature 1000~1790 degrees.
Q:What is the diameter of the ceramic fiber? How to mix?
Fiber length: fiber rejection is longer, the rejection of silk fiber is generally 150-250mm, spinneret fiber is generally 100-200mm;
Q:Aluminum silicate ceramic fiber cotton smoke will cause pneumoconiosis?
Because pneumoconiosis can not be cured by medical treatment, it brings great pains to the patients and the families. It is suggested that respiratory protection work be carried out.
Q:Is aluminum silicate fiber poisonous?
Hello, silicate in the stomach and stomach acid reaction, forming insoluble silicic acid. There should be no toxicity.
