What is the classification of cement fiberboard and cement fiberboard?

Cement fiberboard is favored by many friends in the home improvement market because of its excellent flame retardant effect. Do you also want to know what cement fiberboard is? Bian Xiao will tell you the characteristics and classification of this plate today.

What is cement fiberboard?

Cement fiberboard is a new building material, which is made of siliceous and calcareous materials as main raw materials, modified with natural reinforcing fibers and auxiliary materials, pulped, copied, pressurized and cured.

Fire insulation: non-combustible, Class A, the board will not burn in case of fire and will not produce toxic smoke; It is an ideal insulating material with low conductivity.

Waterproof and moisture-proof: it can still maintain stable performance in semi-open air and high humidity environment without sinking or deformation.

Thermal insulation and sound insulation: low thermal conductivity, good thermal insulation performance, high product density and good sound insulation effect.

Light weight and high strength: the plate pressed by 5000-ton flat oil press not only has high strength, but also is not easy to deform and warp; Light weight, suitable for ceiling and other aspects.

Simple construction: dry operation mode, simple installation and construction of keel and plate, and high speed. Deep processing products also have the characteristics of simple construction and better performance.

Economical and beautiful: light weight, with the cooperation of keel, effectively reduce the cost of engineering and decoration; The appearance color is uniform and the surface is flat. The direct use can make the surface color of the building uniform.

Safe and harmless: it is lower than the national radiation health protection standard of building materials, and the measured index is equal to the lawn value 20 meters away from the surrounding buildings.

Long life: acid and alkali resistance, corrosion resistance, will not be damaged by moisture or insects and ants, strength and hardness will increase with time to ensure a long service life.

Good machinability and secondary decorative performance: materials such as sawing, drilling, carving, drilling nails, painting, sticking tiles, wall covering, etc. can be carried out according to actual conditions.

Introduction to cement fiberboard Classification

1, according to the fiber content

At present, asbestos fiber is mostly used for reinforcement in China, and this kind of fiber cement board is called chrysotile fiber cement board; The other is asbestos-free fiber, which is reinforced by pulp, sawdust and glass fiber instead of asbestos fiber, and is collectively called asbestos-free fiber cement board.

2, according to the density

The low density is 0.9- 1.2g/cm3, the medium density is 1.2- 1.5g/cm3, and the high density is 1.5-2.0g/cm3. Low density is generally used for low-grade building ceiling partitions, medium density is generally used for mid-grade building partition ceilings, and high density is generally used for high-grade building steel structure external walls and steel structure floors. At present, China's fiber cement board is divided into two categories according to the national construction industry standards. The disadvantage of high density fiber cement board is that it is easy to deform, and the deformation coefficient of medium and low density products is small.

3, according to the pressure.

There are no pressure plates and pressure plates. Both medium-density and low-density fiber cement boards are pressureless, while high-density fiber cement boards are pressureless. Pressure plate, also known as fiber cement pressure plate, needs special press production, and enterprises without press can't do it. Fiber cement pressure plates are classified into: 1) ordinary plates with the density of1.5-1.75g/cm3; 2) High-quality board with the density of1.75-1.95g/cm3; 3) High-quality board, the density is above1.95g/cm3.

4, according to the thickness.

(1) ultra-thin plate, 2.5-3.5mm; (2) Conventional plate, 4-12mm; ③ Thick plate,13-30mm; (4) Ultra-thick plate, 31-100 mm. Ordinary manufacturers cannot manufacture ultra-thin and ultra-thick plates, which is also an important basis for measuring the production capacity and technical level of enterprises in the industry.

The above small series introduces what cement fiberboard is and what kinds of cement fiberboard are there. I wonder if you have a deeper understanding of this plate after introducing Bian Xiao?
