This type of equipment mixes polyvinyl chloride (PVC) resin with plasticizers, stabilizers and other auxiliary materials through the extrusion molding process and processes it into flake water-stopping materials, which are widely used in engineering scenarios with high requirements for durability, elasticity and sealing. The PVC waterstop produced by it has corrosion resistance, low temperature resistance (brittle temperature ≤-30°C), high tensile strength (≥12MPa) and good elastic deformation ability, which can effectively adapt to the thermal expansion and contraction of concrete structures and small displacements to prevent leakage.

specific application areas include:

1. Water Conservancy and Hydropower Engineering
   It is used for sealing the construction joints and deformation joints of dams, diversion aqueducts, reservoirs, panel rockfill dams and other structures, such as Goupitan Power Station. Among them, the 861 waterstop is dedicated to the high-slab rockfill dam body.

2. 

3. Transportation infrastructure
   is widely used in subway tunnels, bridge abutments, culverts and other projects, For example, the Beijing Metro project uses PVC waterstop for joint waterproofing.

4. urban underground space development
   suitable for underground comprehensive pipe galleries, civil air defense projects, underground parking lots, Concrete structures such as liquid storage structures that have been in a humid or water pressure environment for a long time to prevent groundwater infiltration.

5. Municipal environmental protection facilities
   In facilities such as water/wastewater treatment plants, flood walls, retaining walls, storage tanks, etc., It is used to ensure the watertightness and durability of the structure.

At present, the mainstream production line has automatic mixing, granulation, extrusion, cooling and cutting functions, and supports the continuous production of various specifications (such as 280×6, 300×8, 350×10mm) and models (651, 652, 861) to meet the design needs of different projects. The equipment is usually provided by professional manufacturers in Hebei and other places, and some manufacturers can also achieve customized configurations according to customer requirements.
