Industry Issues and Challenges
Outdoor durability needs: The outdoor parts of a building, such as the exterior walls and landscape facilities, need to withstand the effects of natural factors such as wind, sun, rain and temperature changes for a long time. Traditional materials such as wood are prone to decay and deformation, stone is costly and complicated to construct, and metal materials may suffer from rust and corrosion.
Fire and safety codes: In building design, especially for some public buildings and high-rise buildings, the fire performance of materials is crucial. Strict building fire codes need to be met to ensure the safety of people and property.
Design Flexibility and Aesthetics**: Building designers often want materials that offer a diverse range of appearance options to achieve unique building shapes and styles, while also harmonising with the surrounding environment.
Customised solutions
Formulation adjustments: For outdoor durability, develop wood-plastic formulations with high weathering resistance. For example, increase the proportion of UV-resistant additives, so that the product is not easy to fade and age under long-term sun exposure; enhance the deformation resistance of the product by optimising the way the plastic matrix and fibres are combined, so that it can withstand temperature changes and humidity changes. For example, in the building and landscape facilities at the seaside, using this highly weather-resistant wood-plastic product to make trestles and railings can effectively resist seawater erosion and strong ultraviolet irradiation.
Fire treatment: In order to meet the requirements of building fire protection, the development of wood-plastic products with added flame retardants. These flame retardants can slow down the rate of flame spread and reduce the amount of smoke generated when a fire occurs. For example, in the external wall decoration of some large shopping malls, the use of fire-treated wood-plastic panels, its fire rating can reach B1 level, in line with building safety standards.
Shape and surface treatment: In order to provide design flexibility, WPC products can be made into a variety of shapes through moulding and other means. At the same time, a variety of surface treatment processes are provided, such as imitation wood grain printing, frosting and high gloss. In the restoration of ancient buildings or the construction of antique buildings, WPC products can be customised into components with traditional wood texture, such as arches, flower windows, etc., which meet the requirements of architectural style and have the durability of modern materials.
