Application of PRE wpc decks in construction engineering

With the growth of my country's national economy, the application of cast-in-place reinforced concrete in the construction industry has become a basic process. The application of cast-in-place reinforced concrete requires the use of building formwork. Traditional building formwork uses pure wood and steel formwork, which is expensive and inconvenient to use, resulting in increased construction costs and reduced economic benefits. With the development of hollow profile wpc decking technology, more and more construction projects use PRE wpc decks, a new material form, as a building formwork for pouring reinforced concrete, which greatly improves the utilization rate of formwork and reduces manufacturing costs. So PRE wpc decks are the most widely used as building formwork in construction projects.

Significance of applying PRE wpc decks as building templates.

The use of PRE wpc decks templates in my country's architectural templates is a choice in response to the national policy of sustainable development, which is in line with the current situation and has many advantages. For example, first, it can effectively alleviate the current situation of my country's timber shortage. Second, to reduce the cost of construction templates, residential wpc decks exterior can use wood chips, leftovers from wood processing, and other residues as raw materials for production. Third, it has good performance and strong durability. PRE wpc decks have mechanical properties such as compression resistance and impact resistance similar to traditional wood. Fourth, in terms of film forming, since PRE wpc decks are comparable to thermoplastic materials, they are easy to process, which provides convenience for film forming of building templates in practical applications. Fifth, the structural durability is strong, and the traditional wood or steel plate formwork cannot achieve the structural durability of PRE wpc decks. Sixth, through the addition of additives, it has variable density, strength, and flame retardancy. Seventh, it is corrosion-resistant, weather-resistant, not easy to absorb moisture and deform, and has a good heat preservation effect. Eighth, it can be recycled and reused and has a certain contribution to environmental protection. It is an environmentally friendly new building template.

Ways to improve the performance of PRE wpc decks for building formwork.

Despite all the above advantages of using easy installation embossed wpc decking as building formwork. However, it is still not perfect, and it is necessary to continuously supplement and improve the performance of the material in the actual application process. These include improving the rigidity and toughness of wood-plastic composite building formwork, reducing the density of PRE wpc decks, optimizing the structure of building formwork, etc. The methods to improve the rigidity and toughness of PRE wpc decks are adding inorganic rigid particles, increasing the thickness of building formwork, and using additives such as toughening agents and coupling agents. Studies have shown that the ratio of woody raw materials and PE is 1:1, and 10% nano-SiO2 is added. Compared with the original material without SiO2 addition, its flexural strength increased by 80%. Nano-SiO2 as a modified inorganic rigid particle can greatly improve the comprehensive performance of PRE wpc decks. During the preparation of PRE wpc decks, the use of toughening agents can greatly improve the toughness of the polymer matrix. The use of a coupling agent can enhance the compatibility of the interface between wood-plastic filler and polymer. The density of embossed customized garden wpc decking can be reduced by foaming and forming a hollow structure, avoiding damage to the formwork caused by the formwork falling, and reducing the cost of use. The principles commonly used in foaming methods are chemical foaming and physical foaming. Chemical foaming is to foam the polymer through a chemical reaction. Physical foaming is to change the physical state of the material to generate a large amount of gas, thereby foaming. Bubble. In terms of optimizing the structure of PRE wpc decks, the shell structure has better overall performance than other structures, so it is recommended to use the shell structure to change the structure of PRE wpc decks.
