　　New material 2.0mm black film for more environmentally friendly biogas digester black film reported today

　　Plant resistance: The anti-seepage membrane has excellent puncture resistance, which can resist most of the plant roots, avoid damage to the anti-seepage membrane, and ensure the service life and functional performance of the anti-seepage membrane.

　　5. Environmentally friendly and non-toxic: The anti-seepage membrane adopts non-toxic and environmentally friendly materials, and the anti-seepage principle is a physical and chemical process. The entire process does not produce toxic substances and does not affect land reuse. 6. The "low cost, high efficiency" black film biogas digester process adopts a new type of anti-seepage membrane technology, making the entire storage process more scientific and concise, and the cost of engineering expenses is much lower than traditional waterproof materials. After actual calculation, the use of this storage process can save about 50% of costs compared to traditional storage processes. 7. Fast construction speed: on-site excavation and film covering can be carried out, with a short installation and construction period, and a single pool film covering can be completed in 3-5 days. Hot melt welding is used, with high weld strength, convenient construction, fast and safe. 8. Diversity of choices: unrestricted use in various regions across the country, unlimited storage areas on site, and no seasonal restrictions; there are three modes to choose from, and domestic customer service can choose according to the actual needs of pig farms. The sentence is:. The development of biogas digesters closely related to the aquaculture industry has gone through a process from underground brick and concrete structure biogas digesters to reinforced concrete biogas digesters and enamel assembled tank biogas digesters. However, the high cost of traditional biogas digesters has deterred many farmers. Gradually developing to red mud biogas digesters, the cost of red film biogas digesters has been reduced compared to previous ones, but the performance is unsatisfactory, especially in terms of not being able to discharge slag. With the continuous introduction of technology, black film soft biogas digesters have quietly emerged. Black film biogas digesters, commonly known as covered lagoons, film covered biogas digesters, and geomembrane biogas digesters. Its biogas production principle is the same as that of the traditional biogas digester. It uses the advantages of HDPE membrane material in seepage prevention and leakage prevention to lay a layer of HDPE anti-seepage membrane in the excavated pit. According to the requirements of anaerobic fermentation process, the inlet and outlet, slag extraction pipe and biogas collection pipe are installed in the tank. The upper mouth of the pit is sealed with HDPE anti-seepage membrane, and the surrounding anchor ditches are fixed to form an overall anaerobic fermentation space. Through practical results, it has been proven that black film soft biogas digesters are more suitable for the pollution control needs of aquaculture farms. The principle is to use black film to absorb heat and improve fermentation efficiency. The construction cost of the tank is one tenth of that of a steel-concrete structure biogas tank and one-fifth of that of a red film biogas tank.

　　Whether in terms of price, gas production, or usage effectiveness, biogas digesters from other processes are far ahead. Nowadays, black film soft biogas digesters have been widely popularized in Guangdong and Guangxi regions. The Guangdong Provincial Environmental Protection Department has recommended this process to breeding enterprises in Guangdong. As of the end of 2016, it is conservatively estimated that black film soft biogas digesters have already occupied one-third of the market in Guangdong region. This process gradually spread to Hunan, Jiangxi, Anhui, Hubei, Hebei and other places. Can this type of black film soft biogas digester be built in northern regions? Actual cases and usage effects have proven to be completely suitable. Jinde geotextile material is exactly the black film soft biogas digester. Hunan black film biogas digesters and Hebei black film biogas digesters are outstanding works of our company. At present, it has been operating stably for several years, producing stable biogas throughout the year. All biogas is used for power generation, which not only meets the needs of enterprise pollution control, but also has significant benefits for biogas power generation. Truly solved the bottleneck problem of traditional biogas digesters with only input and no output.

　　Characteristics of geomembrane for lotus root cultivation

　　1. High anti-seepage coefficient - The anti-seepage membrane has an anti-seepage effect that ordinary waterproof materials cannot compare with. HDPE anti-seepage membrane has high strength and tensile mechanical resistance, and its excellent elasticity and deformation ability make it very suitable for expansion or contraction of the base surface. It can effectively overcome the uneven settlement of the base surface, and has a high water vapor permeability coefficient

　　2. Chemical stability - impermeable membranes have excellent chemical stability and are widely used in sewage treatment, chemical reaction tanks, and landfills. Resistant to high and low temperatures, asphalt, oil and tar, acid, alkali, salt and more than 80 strong acid and alkali chemical media corrosion

　　3. Anti aging performance - the anti-seepage membrane has anti-aging, anti ultraviolet and anti decomposition capabilities, which can be used naked. The service life of the material can reach 50-70 years, providing a good material guarantee for environmental anti-seepage

　　4. Anti plant root system - HDPE anti-seepage film has excellent puncture resistance and can resist most plant roots

　　5. High mechanical strength - The anti-seepage membrane has good mechanical strength, with a fracture tensile strength of 28MPa and a fracture elongation of 700%

　　6. Low cost, low efficiency, high benefits - HDPE anti-seepage membrane adopts a new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is actually lower than traditional waterproof materials. According to actual calculations, the general project using HDPE anti-seepage membrane can save about 50% of the cost

　　7. Fast construction speed - The anti-seepage membrane has high flexibility, with multiple specifications and laying forms to meet the anti-seepage requirements of different projects. Hot melt welding is used with high weld strength, making construction convenient, fast, and healthy
