Waterproof Membrane Aging resistance
HDPE impermeable membrane construction black film biogas digesters have the following advantages:
1, high anti-seepage coefficient: the pool installed in the HDPE impermeable membrane with ordinary waterproof material can not match the anti-seepage effect, will not pollute the groundwater, with high strength tensile mechanical properties, excellent flexibility and deformation capacity to make it very applicable In the expansion and contraction of the base surface, can effectively overcome the uneven surface subsidence.
2, storage convenience: fecal waste can be stored at any time, the storage cycle can be based on fertilization cycle and fecal maturity requirements to determine the feces can be accessed and used.
3, anti-aging: impermeable membrane has excellent anti-aging, anti-ultraviolet, anti-decomposition ability, can be exposed to use, the material life of up to 30 years.
4, anti-plant property: impermeable membrane has excellent resistance to piercing ability, can resist most of the plant plant roots, to avoid damage to the impermeable membrane to ensure that the use of impermeable membrane and function play.
5, environmental non-toxic: impermeable membrane non-toxic environmentally friendly materials, self-defense principle for the physical process, the whole process does not produce toxic substances, does not affect the land reuse.
6, low cost, high efficiency "black film biogas digesters using a new anti-seepage film technology, making the entire storage process more scientific, professional, simple, but also in the cost of expenditure costs far lower than the traditional waterproof material , Through the actual calculation of the use of this storage process than the traditional storage process cost savings of about 50%.
7, the construction speed: local digging pit coating, installation and construction period is short, single pool coating 3-5 days to complete. Using hot-melt welding, high weld strength, construction convenience, fast and safe.
8, the choice of diversity: the use of the region without restrictions, the storage area in the field is not restricted, the season is not restricted; there are three models optional, domestic customer service can be selected according to the actual needs of the pig farm.
9, large storage capacity, to achieve integrated gas storage.
HDPE black film anaerobic biogas process, also known as "Thai black film biogas digesters", scientific name "cover lagoon" biogas sewage treatment system. Has been in Europe and the United States and Southeast Asia large-scale pig farms have a wide range of use. The technology in 2008 the introduction of technology in China, its big advantage is low investment, low operating costs, long residence time, fermented fermentation, can effectively reduce the COD, BOD concentration of sewage. Shanghai Ying Fan company is the first use of the technology HDPE anti-seepage black film production enterprises and black film biogas digesters construction enterprises. HDPE impermeable membrane in 1960 first started by the German use, driving the whole of Europe to use. And then spread to Africa, Australia, North America. Polyvinyl chloride impermeable membrane developed by the United States at the same time, quickly spread to Canada, the former Soviet Union, Taiwan and Europe. In the early 1980s, the United States and Germany received great support for government development.
In 1995, geomembrane sales in North America, for example, HDPE accounted for about 40%, VFPE about 20%, other (CSPE, FPP, etc.) accounted for about 15%. Visible, HDPE impermeable membrane has accounted for about 1/3 of the total geomembrane.
HDPE impermeable membrane introduced into China in 1992, after nearly 20 years of development, widely used in major anti-seepage projects, such as landfill, tailings treatment, high-speed rail non-slip layer, petrochemical and other industries.
