1.5mm HDPE Liner

Product Introduction

     1.5mm HDPE Liner is made of high-density polyethylene (HDPE) as the base material. The ethylene monomer undergoes polymerization to form linear and compact molecular chains, with a crystallinity of 80%-95% and a density of 0.941-0.965g/cm³. By adding 5% carbon black, antioxidants, and light stabilizers, the product's resistance to ultraviolet rays and aging is enhanced. The product has uniform thickness, a tensile strength of ≥30MPa, a elongation at break of ≥700%, a permeability coefficient of ≤10⁻¹³ cm/s, and is suitable for harsh anti-seepage scenarios such as landfill sites and tailings ponds, providing long-term environmental protection protection.

Product parameters

The application of 1.5mm HDPE Liner worldwide

Case 1: A reservoir project in Australia

In a certain area of Australia, to address the irrigation and domestic water supply issues for surrounding farmlands, a reservoir was planned to be constructed. The local soil was mostly composed of sandstone, with deep and interlaced cracks, large gaps, and mixed rocks, resulting in extremely poor water retention capacity. Through experiments, water easily seeped into the soil through the cracks. Additionally, the area had a temperate continental climate with little precipitation, high summer temperatures, strong evaporation, and the eastern mountains blocking moisture, leading to inland aridity.

Based on these circumstances, the project team selected 1.5mm HDPE Liner. Its thickness provided reliable anti-seepage protection, and it was also treated with anti-ultraviolet and anti-aging agents, enabling it to adapt to outdoor environments. During construction, professional welding equipment was used to lay it at the bottom of the reservoir, and the weld seams were strictly processed to ensure a secure connection. After the project was completed, it effectively prevented water infiltration and ensured the water supply.

Case 2: A landfill project in Thailand

In some areas of Thailand, improper waste management led to the contamination of groundwater by landfill leachate, threatening the environment and health. Therefore, the government initiated a related governance project. During the construction of a certain landfill site, 1.5mm HDPE Liner was selected. This material had strong anti-seepage properties and could prevent landfill leachate from seeping. Its chemical stability was good, capable of resisting the erosion of harmful substances in the garbage.

Before construction, the site's base was leveled and cleaned, removing sharp objects. During construction, HDPE Liner was laid in a specific direction, minimizing weld seams. The hot-melt welding technique was used to ensure weld strength. After completion, it significantly reduced the infiltration of external water such as rain into the landfill area, controlled the emission of odors and flammable gases, and reduced pollution risks.

Case 3: A wastewater treatment pool project in the United States

In a certain city in the United States, to upgrade the wastewater treatment system, multiple wastewater treatment pools were built. As the treatment process involved various corrosive chemical substances, the requirements for pool anti-seepage and chemical corrosion resistance were extremely high. 1.5mm HDPE Liner became the ideal choice, as its high-density polyethylene material could resist acid and alkali and other chemical substances' erosion, and its 1.5mm thickness ensured long-term stable anti-seepage effect.

During construction, the pool dimensions were precisely measured, and the laying plan was planned in advance. Skilled welders operated the welding equipment, ensuring the tight connection of each piece of HDPE Liner. After completion, strict testing was conducted, and no leakage occurred, ensuring the efficient operation of the wastewater treatment system and preventing chemical substance leakage from polluting the surrounding soil and water bodies.

Case 4: A mining tailings reservoir project in Brazil

In the tailings reservoir construction of a certain mining area in Brazil, 1.5mm HDPE Liner was used. The tailings contained harmful substances such as heavy metals, and if leaked, would cause great harm. The high strength and puncture resistance of HDPE Liner could withstand the pressure of tailings accumulation and prevent them from being punctured by sharp tailings particles. The 1.5mm thickness enhanced the anti-seepage performance, effectively preventing the leakage of harmful substances.

The construction process followed strict standards, starting with compacting and leveling the bottom of the reservoir, and then laying HDPE Liner in an orderly manner. For complex terrain and corner areas, precise cutting and welding were carried out. After completion, long-term monitoring showed that the tailings reservoir was operating well, without any leakage accidents, effectively protecting the surrounding environment.
