Product Description:

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.

Ceramic Fiber Bulk

Product Description

The polycrystal alumina fiber bulk is made of melted aluminum salt through chemical colloid method.

The solution is heated and inspissated into fiber under specific conditions and got polycrystal alumina fiber after the heat treatment

Ceramic fiber bulk show a high temperature stability.Low weight , heat capacity and an outstanding sound absorption is complemented by their resistance to shock and erosion.

Product Features

Excellent thermal stability and chemical stability

Keep loose ,soft and elastic under high temperature

Low thermal conductivity and heat storage

Excellent thermal shock resistance

No bond and corrosive material

Excellent sound absorption

Product Application

Filling material for expansion gap

Base material for the production of board,paper,profiled fiber

Q:What is the density of ceramic fiber modules? The best insulation effect?
Ceramic fiber module density is only a standard in the world, is 220Kg/m fand, but in the actual application, according to the heat treatment furnace, furnace temperature, combustion medium, temperature rise requirement of ceramic fiber module density in 200-240Kg/m fand, ceramic fiber blanket, because the processing of ceramic fiber module uses double roller today advanced technology and technology of silk, fiber length of the ceramic fiber blanket which produced in 80-130 mm, so the maximum density of the ceramic fiber module is more than the density, 240Kg/m fand, a large amount of fiber fracture, the fracture rate is as high as 48%. So after the actual verification at home and abroad of tens of thousands of industrial furnaces, the best density of ceramic fiber module is fand 220Kg/m.
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 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:What is the difference between the ceramic fiber cloth and the high silicon oxygen cloth?
High temperature is similar to that of strength, service life, the price is high silica cloth. High silica fabric belongs to glass fiber.
Q:Ceramic fiber material fire shutter doors how many square?
Now there are two kinds of rolling to use ceramic fiber: a called inorganic super fire shutter (commonly known as the double track curtain), the curtain surface is glass fiber cloth + ceramic fiber cloth + ceramic fiber blanket + aluminum foil cloth, one is WFJ (glass fiber cloth + ceramic fiber cloth + glass fiber cloth).
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: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 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 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?
Aluminum silicate fiber textiles can replace asbestos textiles, widely used in metallurgy, chemical industry, ceramics. Glass, refractories, shipbuilding, aerospace, automotive, machinery, electronics, building materials, light industry and other industrial sectors of the fire-resistant, heat insulation, fire prevention, friction, sealing, silencing, labor protection, high temperature filtering etc..Landlord, it seems that this material is non-toxic, rest assured that the use of good.
