Product Description:

Description:

Fibre bulks also provide stability and resistance to chemical attack, however, exceptions include hydrofluoric acid, phosphoric acid and strong alkalies (i.e. NaOH, KOH).

 

Fibre bulks are unaffected by incidental spills of oil or water and their thermal and physical properties are restored after drying. They are designed from raw material Calcium-Magnesium-Silicate (CMS) and can be altered to achieve a customer’s desired properties of fibre diameter, shot content, fibre length and form.

Fibre bulks have excellent features such as low biopersistance and heat storage, thermal stability and god resistance to tearing. This material is flexible and resilient, immune to thermal shock and has an excellent thermal insulating

 

performance.

These bulks are ideally suited to individual applications and are available in chopped, un-chopped, lubricated, non-lubricated forms. The maximum continuous use temperature depends on the application.


Application:

 

- Raw material of secondary ceramic fiber products e.g. blanket, paper, board, shapes…

- Expansion joint seal

- Temporary repair of insulation

- Loose insulating fill for complex spaces and areas where access is difficult

- Fiber reinforcement for insulating concretes and cements.

Q:The difference between the ceramic fiber blanket and rock cotton blanket
Refractory 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.
Q:Glass fiber cotton, aluminum silicate cotton, rock wool, what's the difference between these three?
Rock wool: is a kind of insulation materials, widely used in exterior wall insulation, because rock wool dust carcinogenicity, the state has banned the use of industry.
Q:What is the diameter of the ceramic fiber? How to mix?
The diameter of the general ceramic mineral fiber is 2---5 microns, and the length is in the range of 0---8 mm long.Ordinary mixing machine can be easily mixed, and the mixture of other good affinity, evenly dispersed and mixed resin or rubber and liquid glue, thus make the fiber products look pretty smooth, bright color, anti impact friction resistance, small abrasion, tensile Xinghao, can effectively reduce the noise without damage dual, can reduce the amount of metal fiber.
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: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 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?
The main difference between ordinary furnace and ceramic fiber furnace:Refractory, heat insulation: ceramic fiber furnace low thermal conductivity, low thermal conductivity, is a better thermal insulation materials, the use of temperature within one thousand and three hundred Baidu. The heat conductivity of common furnace is higher and the heat loss is great
Q:What is the good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?
Advantages and disadvantages of glass fiber: advantages: good insulation, good heat resistance, good corrosion resistance, high mechanical strength, low water absorption, low price. Disadvantages: brittle, poor wear resistance.
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.
