Hdpe Geomembrane Waterproofing Equipment

The following is some relevant information about HDPE geomembrane waterproofing equipment:

Production line composition

Feeding system: responsible for conveying HDPE raw materials to the extruder to ensure the stability and uniformity of raw material supply.

Single screw extruder: large extrusion volume, stable discharge, one of the core equipment of the production line, heats and melts HDPE raw materials and extrude them.

Hydraulic screen changer: filters impurities during the production process to ensure the quality of extruded materials.

Melt metering pump: accurately controls the flow of melt to ensure uniform thickness of extruded sheets.

Mold: determines the shape and size of the waterproof board, such as the width, thickness of the board, and the structure of the surface pattern or protrusion.

Two-roll forming machine: further forming the extruded sheet, and waterproof boards with different shapes and sizes can be produced by replacing different forming rollers.

Cooling bracket: cools and shapes the formed waterproof board to improve the dimensional stability and physical properties of the product.

Trimming device: cuts off the uneven edges of the waterproof board to make the product edges neat and meet the size requirements.

Tractor: Tractor moves the waterproof board forward at a uniform speed to ensure the continuous operation of the production line and control the stretching degree and tension of the product.

Cross-cutting machine: Cut the continuously produced waterproof board horizontally according to the set length to make the board of the required size.

Friction winding machine: Wind the cut waterproof board into rolls for easy storage, transportation and subsequent use.

Main production process

Extrusion molding: Add HDPE particles into the barrel of the extruder. Under the rotation of the screw, the raw materials are transported forward and gradually heated and melted to form a uniform melt, which is then extruded through the mold to form a waterproof board blank with a certain shape and size.

Cooling and shaping: The temperature of the waterproof board blank after extrusion is high, and it needs to be cooled by the cooling bracket to quickly cool it down and shape it to maintain the shape and dimensional accuracy of the product.

Cutting and winding: The cooled waterproof board is cut by the cross-cutting machine according to the required length, and then the friction winding machine winds the cut waterproof board into rolls.

Product Features

High Strength: HDPE waterproof sheet has high tensile strength and tear strength, can withstand large tension and pressure, and is not easy to break.

Corrosion resistance: It has good corrosion resistance to chemical substances such as acids and alkalis, and can maintain stable performance under harsh environmental conditions.

Weather resistance: It can be used for a long time under different climatic conditions and is not easily affected by factors such as ultraviolet rays and temperature changes.

Good anti-seepage performance: It has excellent anti-seepage performance and can effectively prevent liquid penetration. It is widely used in anti-seepage projects in water conservancy, environmental protection and other fields.

Convenient construction: The material is light, easy to carry and construct, and can be connected and installed by welding, bonding and other methods.

Application Field

Construction Engineering: Used for anti-seepage treatment of basement floor and roof, as well as anti-seepage and waterproof layer protection of building foundation, inner and outer wall of basement, etc.

Traffic Engineering: It plays a role in anti-seepage, reinforcement and protection in tunnels, highways, railway roadbeds, dams, slope protection and other projects.

Municipal engineering: suitable for anti-seepage and drainage treatment in places such as subways, roadbeds, and landfills.

Garden engineering: can be used for waterproofing, drainage, and root isolation treatment of underground garage roof planting, roof greening, football fields, golf courses, and other places.

Some manufacturers

Haiming Machinery: Its HDPE drainage board production line uses a single-screw extruder with large extrusion volume and stable discharge, PID control, and good temperature control and energy-saving effects. There are multiple options for product width, thickness in the range of 0.5-3mm, and the output varies according to the extruder model.
