Product Introduction
1、 Basic attributes
Material essence: HDPE Pond Liner Sheet is a thin film or sheet-like flexible material made from high-density polyethylene (HDPE) as the main raw material through extrusion, rolling and other processes, with a thickness usually ranging from 0.3-2.0mm and a single roll area of several hundred square meters.
Physical characteristics: Lightweight texture (low weight per unit area), good flexibility, high crystallinity, dense molecular structure; At room temperature, it is solid and can be tightly joined through hot melt welding.
Environmental attributes: Produced using food grade or environmentally friendly HDPE raw materials, free of heavy metals, harmful additives, etc., in compliance with environmental standards, non-toxic to water and soil pollution.
Applicable environment: With a wide temperature tolerance range (-60 ℃~60 ℃, stable performance), it can be used for a long time in complex environments such as open air, humidity, and high sediment.
2、 Core functions
Efficient anti-seepage: By using a dense molecular structure and a complete splicing process, water molecules, liquids, or gases are prevented from penetrating, reducing pond water source leakage. The anti-seepage efficiency can reach over 99%, which is the core and most critical function.
Soil and water isolation: Isolate the pond water from the bottom soil, avoid mutual infiltration of substances (such as sediment and harmful chemical ions) between the water and soil, protect soil ecology, and maintain water cleanliness.
Structural protection: withstand external forces such as water pressure, fill weight, and placement of aquaculture equipment, resist punctures from sharp objects (stones, tree roots) in the soil, and protect the integrity of the pond structure.
Ecological assistance: Reduce sediment content in water bodies, lower water turbidity, and provide a stable ecological environment foundation for aquaculture or landscape water bodies.
3、 Main features
Strong durability: after adding antioxidant and ultraviolet stabilizer, the anti-aging and weather resistance are excellent, and the service life can reach 10-30 years; Simultaneously resistant to acid and alkali, resistant to corrosion from aquaculture agents, and not easily degraded by chemical reactions.
Convenient construction: easy to transport, can be quickly laid manually, and can adapt to irregular terrain (such as slopes and corners); The hot melt welding process is mature, and the weld strength is higher than that of the base material, with high splicing efficiency (1-2 meters/minute).
Outstanding cost-effectiveness: The initial cost is higher than traditional clay and ordinary film, but due to its good anti-seepage effect, low maintenance cost (no need for frequent repairs), and less water resource waste, the long-term comprehensive cost is lower.
Multi functional adaptation: In addition to pond anti-seepage, it can be extended to be used for artificial wetland lining, reservoir anti-seepage, landscape water anti-seepage and other scenarios. Some models can also have characteristics such as root thorn resistance and anti slip, adapting to various needs
