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.

FAQ
Q1: How do you control the products quality?
A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.
Q5: Can you give me a brief introduction of the application of your products?
A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals
- 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 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: 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: 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 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.
- Q: Is aluminum silicate fiber poisonous?
- Ceramic fiber loose cotton is a kind of fluid which can melt high purity clay clinker, alumina powder, silica powder, chrome sand and so on in the industrial electric furnace.
- 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: 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: 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: Ceramic fiber material fire shutter door how many square?
- If the above two kinds of roller blinds, really true to do, the former per square meter at least 500 yuan, and the latter at least 400 yuan per square meter. Otherwise, there must be a problem.
