Which composite board is better to choose? How to choose composite board?
A single board cannot meet the specific needs of use. I believe people who have used the board will feel it. Therefore, there are more people considering the composite board. So which composite board is better? How to choose composite board?
Which composite board is better to choose?

1. Metal composite board

The product does not change the nature of the matrix itself, overcomes the shortcomings of the matrix itself, exerts its advantages, has strong wear resistance and corrosion resistance, and has good weldability, extensibility, formability and decoration. It can meet the material requirements of different workpieces. For example, materials with high anti-corrosion requirements can be made of titanium, stainless steel and other materials as anti-corrosion surfaces; and materials that require good heat dissipation and electrical conductivity can be made of copper, aluminum and other materials as the main body of heat conduction; require light weight, The strong ones can be made of composite plates with aluminum as the main body and stainless steel or titanium steel as the secondary body.
2. Color steel composite board

The product is light in weight, only equivalent to 1/30 of a brick wall, has good thermal insulation and sealing performance, high strength, can be used as a maintenance, load-bearing structure, and is resistant to bending and compression. Bright color, beautiful appearance, no need for surface decoration. The construction is convenient, the installation is quick and flexible, and the construction period can be shortened by more than 40%.

3. Rock wool composite board

The product has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. In the process, pressure, trimming, groove pressing, and blanking are used to form a tongue-and-groove composite board with good integrity, high rigidity, and mechanical properties of impact resistance and shear resistance, heat preservation, heat insulation, sound insulation, and moisture resistance Features. The length of the rock wool composite board is not limited and can reach more than 12 meters, which fully meets the fire protection requirements of technical design, and overcomes the defects of insufficient integrity and rigidity, poor flexural and impact resistance in the past.

4. Aluminum-plastic composite panel

The product is easy to process, simple to install, stable internal stress, good rigidity, and has super strong adhesion. After 8 hours of boiling water experiment, the bonding layer did not appear to be damaged. The modified flame-retardant polyethylene core material is non-toxic, scientific and environmentally friendly, and pollution-free. The two sides are coated with non-combustible aluminum layer. The fire performance test exceeds the B1 level index requirement, which solves the fire protection problem of metal-plastic composite building materials.
How to choose composite board?

The key points of composite board selection, the following seven points are worth paying attention to:

1. Look-whether the surface of the composite board is smooth, without ripples, bubbling, shelter, or scratches.

2. Test-measure whether the composite board meets the international requirements, such as the thickness of the aluminum-plastic board, the inner wall board is 3mm, the outer wall board is 4mm or more, and the thickness of the aluminum must be 0.5mm.

3. Folding-at the corner of the composite board, it is not the composite board made of high-quality materials that is easy to break. Generally speaking, the composite board made of high-quality raw materials has certain flexibility.

4. Burning-the middle material of the composite board, the real PE can be completely burned, and the doping will cause impurities after the fake burning.

5. Planing-When the groove is bent, check whether the front side is broken.

6. Drops-methyl ethyl ketone to identify fluorocarbon coatings on exterior wall panels, drop xylene to identify interior wall panels coatings, wipe off the reagent after 5 minutes to see if the bottom is exposed.

7. Required-Ask for manufacturer's quality inspection report, warranty certificate, and ISO-9002 international quality certification. The manufacturers who own these are produced by regular manufacturers, which can guarantee the quality of the product, the same price is more than the quality, and the same quality is more than the price.
