Product Description

Ceramic Fiber Bulk for heat insulation

Ceramic fiber bulk is made of coal gangue by melting 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, ceramic 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,also lightweight,heat insulation,

low thermal conductivity etc.


Ceramic fiber bulk application 

(1)Raw material for fiber blanket, board products; Raw material for fiber textile products;

(2) Joint sealing and filling insulation for industrial kilns and fuming channel and high temperature pipes

(3) Raw material wet processed products; 

(4) Fiber spraying;

(5) Raw material for coatings and castables; 

(6) Insulation fillings for corner and complex space.

Q:The difference between the ceramic fiber blanket and rock cotton blanket
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.
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:What is the diameter of the ceramic fiber? How to mix?
Fiber diameter: rejection fiber more coarse, rejection fiber generally 3.0-5.0 - m, spinneret fiber is generally 2.0-3.0 - m;
Q:What is the difference between the ceramic fiber cloth and the high silicon oxygen cloth?
Ceramic fiber is a short fiber that needs to be reinforced and toughened by other objects. It is generally toughened by glass fiber and stainless steel wire. The high silicon oxygen is long fiber, no need to toughen by other objects. The short-time high silica resistance to high temperature, Suzhou Dexin ceramic high silica cloth of silica content is greater than or equal to 96% temperature up to 1700 DEG C.
Q:Aluminum silicate needle carpet and ceramic fiber insulation performance of the good
Aluminosilicate ceramic fiber has two different production processes, respectively, the rejection process and the blowing process. The carpet produced by the spinning process has long fiber length, high tensile strength and wide range of use. The blanket produced by blowing process is short in length and easy to break, and the scope of application is relatively narrow.
Q:Aluminum silicate ceramic fiber cotton smoke will cause pneumoconiosis?
Most of the aluminosilicate ceramic fiber cotton with high quality bauxite, high purity alumina, silica, zircon sand as raw materials, by blowing or swinging method generated by fiber, cotton collector or settlement device assembled into bulk fiber, also known as cotton fiber. Therefore, according to its composition, after inhalation, will lead to pneumoconiosis.
Q:Should the ceramic fiber furnace be compacted
In view of the large industrial furnace, the ceramic fiber module can be chosen to be refractory, heat insulated and insulated, and the ceramic fiber module is firmly fixed on the furnace wall by the parallel mounting method, which is more reliable
Q:Is aluminum silicate fiber poisonous?
Hello, silicate in the stomach and stomach acid reaction, forming insoluble silicic acid. There should be no toxicity.
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:Is the ceramic fiber cloth poisonous?
With aluminum, zinc and other non-ferrous molten metal erosion capacity. Excellent high temperature strength. The bottom heat conductivity makes the product have good heat insulation performance. Excellent electrical insulation performance. Non-toxic, harmless, no adverse effects on the environment, excellent tensile properties.
