Fiber cement board is divided by fiber: at present, most of the domestic use asbestos fiber for reinforcement
.
Ordinary manufacturers cannot make 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..

.
It is also the best fire-retardant material for indoor decoration fire-retardant projects in large shopping malls, hotels, hotels, document halls, closed clothing markets, light industry markets, cinemas and other public places

.
Economy: according to the national standard requirements for external thermal insulation and energy saving of building exterior wall, this product has higher cost performance compared with other similar thermal insulation products
.
It has fire prevention and thermal insulation performance and is used by many builders in various large-scale engineering construction projects
.
Fiber cement board is divided according to thickness: 1) ultra thin board, 2.5-3.5mm; 2) Conventional plate, 4-12mm; 3) Thick plate, 13-30mm; 4) Super thick plate, 31-100mm
.
Fiber cement board for exterior wall, also known as fiber reinforced cement board, refers to the board made of cement as the basic material and adhesive, mineral fiber cement and other fibers as the reinforcement, through pulping, molding, maintenance and other processes
Medium and low density exterior wall panels are non pressing plates, and high-density exterior wall panels are pressure plates
.
Dry operation, no pollution, fast construction and good effect
.
According to the density, the fiber cement pressure board is divided into: 1) ordinary board, with a density of 1.5-1.75g/cm3; 2) Superior board, density 1.75-1.95g/cm3; 3) Premium board, with a density of more than 1.95g/cm3

Convenience: the metal surface thermal insulation curtain wall board adopts special building thermal insulation curtain wall anchor bolts to embed the large thermal insulation curtain wall board on the external wall surface of the building safely, accurately and quickly
.

.
Light weight: the surface density of metal surface thermal insulation curtain wall board is only 50% of that of traditional external wall external thermal insulation materials, and the surface density per square meter is only 4-8kg, which reduces the white weight of the structure of the external wall of the building
.
Exterior wall panel is the main decoration material of building facing structure

Fiber cement board is divided according to density: low density 0.9-1.2g/cm3, medium density 1.2-1.5g/cm3 and high density 1.5-2.0g/cm3
.
High density exterior wall panels are easy to deform, and the deformation coefficient of medium and low density products should be smaller
.
Decoration: the external surface of the external wall can imitate natural stone, metal aluminum-plastic plate curtain wall, aluminum veneer curtain wall, decorative ceramic tile and other decorative effects, meet the requirements of high-grade appearance decoration, and have sufficient safety and reliability

Fiber cement board is divided according to pressure: whether there is pressure plate and pressure plate
.
Pressure plate, also known as fiber cement pressure plate, needs special press production, which can not be done by enterprises without press
.
The exterior wall panel is used in the fire prevention and flame retardant of cable engineering in various power plants, chemical enterprises and other places with dense electricity charges in China
.
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, and high density is generally used for steel structure exterior wall and steel structure floor of high-grade building; At present, China’s foreign wallboards are divided into two categories according to the national construction industry standards

.
Thermal insulation: the thermal conductivity of the core material of metal surface thermal insulation curtain wall panel is controlled between (0.021-0.041), which can meet the design specification requirements of national standard building energy saving of more than 65%
.
This kind of exterior wall board is called chrysotile asbestos fiber cement plate; The other is asbestos free fiber, which is reinforced by pulp, sawdust and glass fiber instead of asbestos fiber
.
At the same time, the core material with different thickness (EPS, XPS, PUR, etc.) can be selected according to the region
