Plastic Drainage plate ，It is a plate made of high molecular polymer with drainage function. Through special process treatment, it forms an uneven surface structure, which can export moisture, reduce the hydrostatic pressure of the waterproof layer, and achieve waterproof effect.
1. The main raw materials of plastic drainage board
1、Polystyrene ( HIPS）
Polystyrene is a common thermoplastic with very good processability and high strength. In the production of plastic drainage boards, polystyrene is processed into sheets with concave-convex structures, and drainage channels are formed by stamping or extrusion processes. However, polystyrene is relatively weak in weather and corrosion resistance, and may age and embrittle when exposed to outdoor environments for a long time.
2、Polyethylene ( HDPE）
Polyethylene is a high-density, high-strength thermoplastic with very good corrosion, weather and impact resistance. In the production of plastic drainage boards, polyethylene can be processed into sheets with continuous drainage channels, which are connected together by thermal welding or mechanical fixation to form a complete drainage system. Polyethylene drainage board has a long service life and good drainage performance, and can be used in waterproofing projects such as basements and roofs.
3、Polyvinyl chloride ( PVC）
Polyvinyl chloride is a thermoplastic with very good processability and high strength. Compared to polystyrene and polyethylene, PVC has better flame retardancy and chemical corrosion resistance. In the production of plastic drainage board, polyvinyl chloride is processed into board with concave-convex structure, and drainage channels are formed by extrusion or calendering process. PVC drainage board not only has excellent drainage properties, but also resists acid and base corrosion and fire threats.
4、Polypropylene ( PP）
Polypropylene is a lightweight, high-strength thermoplastic with very good weather and corrosion resistance. In the production of plastic drainage boards, polypropylene is processed into sheets with continuous drainage channels, which are joined together by thermal welding or mechanical fixation. Polypropylene drainage board has light weight and good drainage performance, which is suitable for drainage systems of roads, tunnels and other projects.
2. The influence of raw material selection on the performance of plastic drainage board
The choice of raw materials has an important impact on the performance of plastic drainage board. Drainage boards made of different raw materials differ in strength, corrosion resistance, weather resistance, flame retardancy, etc. Therefore, when choosing a plastic drainage board, comprehensive consideration should be made according to the specific engineering needs and geological conditions, and the most suitable raw materials and drainage board type should be selected.
As can be seen from the above, the raw materials of plastic drainage board mainly include polystyrene, polyethylene, polyvinyl chloride and polypropylene. Drainage boards made of different raw materials have differences in performance, so they should be selected according to specific engineering needs.
