Weathering board material and performance
The weather-resistant board is mainly made of polyester fiber and glass fiber. The polyester fiber weather-resistant board is made of modified resin, high-performance matrix material and special processing, which has high impact resistance. Plate.
1. Advantages of weather-resistant boards
1) High strength
Polyester fiber weather-resistant boards are based on modified resin and add high-performance matrix Material (carbon fiber or glass fiber), a special decorative plate with high strength and high modulus made through special processing. Its density is only 1.18g/cm3, which can greatly reduce the weight of the building; its tensile strength is greater than 400MPa, the elongation at break is greater than 600%; the elastic modulus is greater than 500MPa, and it has good bending resistance.
2) Good toughness
Due to the use of special production technology, a uniform and dense anti-ultraviolet layer (UV absorber) is formed on the surface of the product, effectively preventing ultraviolet rays from damaging the board. harm. At the same time, the product has toughness: it can maintain good physical and mechanical properties in the range of -40°C to 150°C; it will not crack, warp or crack under dry conditions; it will not become sticky or deform under wet conditions, etc. .
3) Wear resistance
Because there is a protective film against ultraviolet rays (UV absorber) on the surface of the product, it effectively prevents fading caused by ultraviolet rays. Therefore, the service life of the product can be as long as above or even longer. (It varies according to different uses and conditions of use.)
4) Environmental protection
No formaldehyde adhesives and other harmful gas emissions are used to pollute the environment during the production process .Comply with the requirements of green environmental protection. It is non-toxic, tasteless, radiation-free and pollution-free. It is a green and environmentally friendly product. (Please contact us for details) It has good waterproof, anti-corrosion and moisture-proof performance. It can effectively avoid adverse factors such as rain, sun and other bad weather and acid rain corrosion. Impact.
5) Color and luster are stable
Using this series of products, the colors are rich and diverse and long-lasting without discoloration. Any color and gloss effect can be customized according to user requirements. It can meet the needs of designers and owners. It can also be used as a decorative material for ceilings, ceilings, skirts, wall decorations and various partition screens in interior decoration design. 2. Disadvantages of weather-resistant boards
(1) Higher price
Generally, the price per square meter is more than 1 yuan
(2) Construction is difficult
Due to the high cost of raw materials, the price of finished products is high
(3) Not resistant to high temperatures
Not resistant to high temperatures and prone to softening and deformation
(4) Easy to absorb moisture
Easy to absorb moisture but not easy to dry
< p>(5) Poor fire resistance
Flammable
(6) No direct contact with open flames
