　　Mining (anti-seepage of washing tank, heap leaching tank, ash yard, dissolution tank, sedimentation tank, tailings yard, sewage storage tank, etc.)

　　Characteristics of black film biogas digesters: 1. High anti-seepage coefficient of black film biogas digesters: The anti slip film installed in the digester has an anti slip effect that ordinary waterproof materials cannot match, does not pollute groundwater, has high-strength tensile mechanical properties, excellent elasticity and deformation ability, making it very suitable for expansion and contraction base surfaces, and can effectively overcome uneven settlement of the base surface. 2. Storage convenience: Feces can be stored at any time, and the storage period can be determined according to the requirements of fertilization cycle and manure maturation period. Feces can be accessed and used in various ways. 3. Aging resistance: the anti-seepage membrane has anti-aging, anti ultraviolet and anti decomposition capabilities, and can be used outdoors. The service life of the material can reach 30 years. 4. 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.

　　Composite waterproof board; A waterproof material formed by thermal composite of polyester polyester short filament (long filament) geotextile and waterproof board. The width is 1-7m, and the material of the waterproof board is as follows:; LDPE, HDPE, EVA, ECB. The commonly used materials for tunnel, subway, culvert, and civil air defense engineering are EVA, ECB, and waterproof board width; 1-3 meters,; composite; 1.0mm/200g，1.2mm/300g，1.5mm/300g，1.5mm/350g，200g/1.0mm/200g，250g/1.5mm/250g。 Point hanging waterproof board; 0.8-2.0mm thickness, can be produced according to customer requirements.

　　The composite forms of tunnel waterproof board include:; Sling style, strip style, fully composite, two fabric composite, one fabric composite. Its main role in engineering; Waterproof and anti-seepage. The product has high physical and mechanical performance indicators such as tensile strength, tear resistance, and burst resistance. It has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, crack prevention and strengthening in water conservancy, municipal engineering, construction, transportation, subway, tunnel, and engineering construction. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.

　　Tunnel waterproof boards are generally divided into separate waterproof boards and composite waterproof boards, with materials includingEVAandECBThere are two types of separate tunnel waterproof boards. Generally, the board and geotextile are used separately, while the composite waterproof board is generally made by combining geotextile and board heat, and can also be compounded with asphalt adhesive (self-adhesive composite waterproof board) on one side of the board. The geotextile commonly used on the waterproof board is generallythree hundredKe orthree hundred and fiftyKe's geotextile.
