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: 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: 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 ceramic fiber cotton smoke will cause pneumoconiosis?
- 1, general masks, gauze, masks, etc., can not be used as dust masks.2, mask must pass GB 2626-2006 standard certification.3, it is recommended to choose N100 class dust masks.4, individual suggestions according to choose different shapes masks.5, it is recommended to change the filter gauze mask. Material recommended for silicone material.Through the above way, it can effectively prevent pneumoconiosis.
- 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.
- 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 good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?
- Advantages and disadvantages of aluminum silicate fiber: high temperature insulation, heat preservation, fire resistance, noise reduction, insulation, light weight. Disadvantages: compressive resistance, bending force is relatively poor, easy to produce dust, waterproof performance is not very good.
- 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: 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.
