HDPE landfill liner, also known as landfill geomembrane, is an effective waterproof geosynthetic product water or waste containment applications. As the most durable impermeable geomaterial, inherently very resistant to stress cracking and extremely resistant to most chemicals, the HDPE landfill liner is very popular in the mining industry. GEOSINCERE high-quality geomembrane is divided into smooth geomembrane, textured geomembrane, composite geomembrane, etc. GEOSINCERE brand HDPE geomembrane has passed ISO9001, ISO14001, TUV, Soncap, SASO, BV and other certifications, and passed the testing of SGS, Intertek, etc., The landfill geomembrane, especially 1.5mm thickness HDPE geomembrane liner is widely used in mining, aquaculture farm projects, wastewater treatment, landfill and salt ponds, etc.
1. What Is A Landfill Liner?
A landfill liner is a type of engineered barrier system used in the construction of landfills to prevent the migration of contaminants into the surrounding environment. It is constructed between waste materials deposited in a landfill and the underlying soil and groundwater.
The function of a landfill liner primarily focuses on pollution reduction and preservation of an ecosystem. It involves various layers that act together to form an impermeable shield. In particular, landfill liner systems are typically composed of:
Low-permeability liner: Its composition generally includes geomembrane materials such as high-density polyethylene (HDPE) or clay liners. This level serves to stop leachate (a liquid produced through decomposition of waste) from entering into the underlying soil and groundwater.
Geosynthetic clay liner (GCL): Sometimes, low permeability liners may be replaced by GCLs or they can be added to it. The layer consists of bentonite clay which separates two geotextiles making it perform better hydraulically and have more capacity for holding pollutants.
Protective layer: A protective layer consisting mostly made up of geotextile fabric is laid on top of either low-permeability liner or GCL so as to prevent piercing or damage during dumping activities.
The main mechanism of landfill liner is that the water-impermeability of the plastic film blocks the leakage channel of the earth dam, and it can withstand water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation; and the non-woven fabric is also a kind of polymer short fiber chemical. The material, formed by needle punching or thermal bonding, has high tensile strength and extensibility. After it is combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also because the surface of the non-woven fabric is rough. , which increases the friction coefficient of the contact surface, which is beneficial to the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemical effects, are not afraid of acid, alkali and salt erosion, and have a long service life when used in the dark.
2. Why Chose HDPE Landfill Liner for Ming Project in Mongolia?
In the past 30 years, the traditional soil-cement stacking method used in projects such as Mongolian mining reservoirs has been replaced by the emerging HDPE geomembrane liner. Geomembrane landfill liner is widely used in the mining industry today to line solution and evaporation ponds, tailings impoundments and heap leach pads. Tailings contain a variety of useful (eg, re-separable metallic or non-metallic minerals) materials. Sulfide in tailings produces acidic water and further leaches heavy metals. If not stacked properly, the loss will seriously damage the soil and ecological environment. When storing tailings, it is easy to flow and collapse, causing damage and injury, especially in the rainy season, which is prone to landslides and landslides. Hazardous substances in tailings are also very harmful to the environment. When soil is polluted, it will be salinized and poisoned. Pathogens and other pathogens in soil can make people sick, and infiltration can also contaminate pipes and end up in the food chain. Serious harm to human body. When storing tailings, it is easy to flow and collapse, causing damage and injury, especially in the rainy season, it is very easy to cause landslides and landslides. It may also cause environmental pollution, soil erosion and replacement damage in the mining area.
HDPE geomembrane has good physical and chemical resistance, so it is widely used in mining applications such as heap leaching of mineral-bearing rocks, grinding tailings treatment, and evaporation or solar ponds to recover salts. We use geomembrane to isolate underground heavy metals from soil to prevent the interaction between heavy metals and soil; second, the new mining method is easy to install, saves costs and reduces maintenance costs. Today’s mining engineering projects have required the use of geomembrane in the tender.
A Mongolian customer left a message on the Google Geomembrane website to tell us that he needed to buy 1.5mm geomembrane for a mining project, and asked about the price of the 1.5mm geomembrane. It was learned by email that the customer wanted the 1.5mm geomembrane we provided to meet the GM13 standard.
3. How To Use Landfill HDPE Liner for Ming Project in Mongolia?
We always to provide customers with GM13 standard geomembrane landfill liner, which can effectively isolate soil pollution. Based on our experience, we presented our landfill geomembrane case in the Ming project to our Mongolian client. And in the further discussion, we know that the Mongolian customer’s mining project geomembrane needs to be purchased together with the geotextile. In order to convince customers of the quality of our products, we mailed geotextile and 1.5mm geomembrane liner samples and SGS test certificate to customers. The customer received the sample one week later and was very satisfied with the quality of our geomembrane landfill liner samples. In order to further deepen the understanding of geomembrane manufacturing, a Mongolian customer told us that he needed a video factory audit. In the afternoon of the same day, we introduced the whole process from raw materials to production to loading to customers in detail in the form of live video. We browsed our production equipment, quality inspection, etc. together with customers. Customers appreciate this method of production. Customers recognized the professionalism of geomembrane after seeing our production process and tensile test.
High-density polyethylene (HDPE) is a high-density version of PE plastic that is harder, denser than LDPE, and lighter than water. The yield tensile strength of HDPE geomembrane can reach 24kn/m, and the breaking strength is higher than 42kn/m. Such a high index can be used in a variety of harsh geological and climatic conditions to adapt to uneven geological subsidence. Due to the advantages of geomembrane itself, the use of geomembrane in mining projects has been widely used.
After we confirmed all the details about the order with the customer, the customer paid us 30% prepayment. Considering that the customer urgently needs the geomembrane landfill liner to do the project, we arranged the production as soon as possible, worked overtime to ensure the quality and quantity, and completed the production within three days. The customer received the geomembrane, and under the guidance of our engineers, it was completed. All installations have since maintained a mutually beneficial and win-win partnership with customers.
4. What Are Benifits of HDPE Landfill Liner for Ming Project in Mongolia
(1) High strength. The tensile strength of our landfill liner at yield can reach 24kn/m, the tensile strength at break can reach 42kn/m, and the ductility is good. The elongation at yield is 13% to 16%, and the elongation at break is 700% to 800%. Has good surface compliance and weather resistance. When it reaches its peak, the strain is about 1000%. Especially for the ground and sides of ponds, which need to withstand the pressure alone, this physical property makes mining projects safer and more durable.
