What are the categories of fiber cement board? 10 things You need to know about it!

Fiber cement board, in fact, is a kind of plate. It is made from cement and mineral fibers. At present, in our country, the fiber cement board is used in power plants and chemical plants as a very excellent flame retardant material. There are many different kinds of it at different levels. Therefore, Xiaobian will introduce to you its classification, as well as the remarkable advantages of this building material. Keep reading, you can learn a lot of knowledge oh!

   一、the classification of fiber cement board

1, according to the fiber to divide

Most of the domestic use of asbestos fiber to enhance the effect, this fiber cement board is called chrysotile fiber cement plate; The other is not containing asbestos fiber, with pulp, wood chips, glass fiber to replace asbestos fiber to strengthen the role of asbestos fiber are collectively referred to as asbestos-free cement plate.

2. Divide by density

Low density 0.9-1.2g/cm3, medium density 1.2-1.5g/cm3, high density 1.5-2.0g/cm3. Low density is generally used for low-grade building ceiling partition wall and other parts, medium density is generally used for medium-grade building partition wall ceiling, high density is generally used for high-grade building steel structure exterior wall, steel structure floor, etc. The disadvantage of high density fiber cement board is easy to deform, and the deformation coefficient of medium and low density products is smaller.

3. Divide by pressure

There is no pressure plate and pressure plate. Medium and low density fiber cement board is no pressure plate, high density is pressure plate. Pressure plate is also called fiber cement pressure plate, the need for special press production, no press enterprise can do. According to the density of high and low, fiber cement pressure plate is divided into: ordinary plate, excellent plate, special excellent plate.

4, according to the thickness

Thin plate 2.5-3.5mm, conventional plate (4-12mm), thick plate (13-30mm), thickened plate (31-100mm), the general manufacturers can not make thin plate and thickened plate, which is also an important basis for measuring the production capacity and technical level of enterprises in the industry.

    二、The advantages of fiber cement board

1, green environmental protection: 100% free of asbestos, benzene, formaldehyde and other harmful substances, the use process does not produce toxic gas or radiation. Green, safe and healthy!

2, fire retardant: the plate is A1 grade non-combustible material, will not burn, even in the fire will not produce toxic smoke, no flame transmission. And low thermal conductivity, good thermal insulation performance!

3, waterproof and moisture-proof: the board performance is stable, wet rise rate, dry shrinkage rate is low, even in the open air or wet areas also have good waterproof, moisture-proof, frost proof performance.

4, thermal insulation: the board uses high grade cement and plant fiber structure, and polyurethane board and other composite formation of the integrated board, thermal insulation performance advantage is significant, greatly reduce building energy consumption.

5, anti-corrosion and mothproof: the material is exquisite, the technology is advanced, so that the plate is anti-aging, anti-weathering, good durability, will not mold and rot, all kinds of insects and ants can not do anything about it.

6, sound insulation and sound absorption: the board has good sound insulation performance, and can be combined with other sound-absorbing materials to meet the requirements of all kinds of sound insulation walls or barriers.

7, good earthquake resistance: with the plate as a partition wall, the weight is only 1/15 of the brick wall of the same thickness (can effectively reduce the construction cost), which is conducive to the structure of earthquake resistance.

8, light and high strength: the weight of the plate is light, high strength, good toughness, thin plate can even do arc coating, easy to construct and handle, not easy to damage.

9, good weather resistance: high density board by ten thousand tons of press compact, the product dry shrinkage wet rise performance and strength greatly improved, with excellent weather resistance, long service life.

10, convenient construction: the board is usually dry construction, fast and convenient, do not need to plaster, can be directly sprayed paint; Easy to drill, planing, sawing and other secondary processing.

Well, to sum up, it is a news report on the classification and advantages of fiber cement board brought by Xiaobian. Hope it will be helpful to you!
