Functional innovation of building plastic materials continues to upgrade. The "easy-to-install plastic drainage board" developed by Shandong Yonghao Engineering Materials Co., Ltd., through the collaborative design of vertical and edge limiting components, completely solves the problem of traditional drainage boards easily lifting at the joints, ensuring the flatness of the paving and construction efficiency.

This patent technology not only enhances the performance of plastic drainage boards but also reduces installation complexity through structural optimization, providing a more reliable material choice for drainage system construction in fields such as underground engineering and landscaping, demonstrating the technical potential of plastic materials in functional building applications.

In terms of production process innovation, the patent "High Formation Rate Extruder and Method for PVC Pipe Manufacturing" by Guangzhou Haojian Plastic Technology has attracted attention. This technology achieves precise control of the plastic raw material feeding speed through the联动设计of the feeding mechanism and the plasticizing mechanism, and uses the heat dissipated during the plasticizing process to pre-dry the raw materials, significantly improving the molding quality and production efficiency of PVC pipes. Note: The term "联动设计" was left in Chinese as it directly refers to a specific design concept which may not have a direct equivalent in English without additional context. A more natural translation might require understanding the specific technical meaning intended.

This innovation not only optimizes the manufacturing process of plastic pipes but also reduces energy consumption and raw material loss, providing technical support for the efficient and stable operation of building water supply and drainage systems.

The large-scale application of hollow plastic formwork is becoming an important direction in the development of building plastic materials. High-turnover hollow plastic formwork, with its characteristics of light weight, high strength, and environmental friendliness, shows significant advantages in residential, commercial, and infrastructure construction.

Its internal hollow structure design significantly reduces weight while ensuring strength, and combined with its smooth surface characteristics, it enables convenient concrete demolding and improved molding quality. Additionally, the high turnover performance of 50-100 times significantly reduces construction costs, and its recyclable nature better aligns with the concept of green buildings. With technological iteration and market promotion, this type of material is gradually becoming an important driving force for sustainable development in the construction industry.
