2.0 HDPE geomembrane special high-density anti-seepage membrane for tailings pond in Xizang

Description :

　　Xizang 2.0HDPE geomembrane (special high-density anti-seepage membrane for tailings pond),

　　The climate of Xizang is unique, complex and diverse due to the influence of topography, landform and atmospheric circulation. The climate generally has the characteristics of severe cold and dry in the northwest and warm and humid in the southeast. Therefore, the climate types from southeast to northwest include tropical, subtropical, plateau temperate, plateau subarctic, plateau frigid, and other types. In the mountainous and canyon areas of southeastern Tibet and the southern slope of the Himalayas, due to the repeated elevation of terrain, temperatures gradually decrease, and the climate undergoes vertical changes from tropical or subtropical to temperate, cold temperate, and cold belt climates.

　　The general characteristics of 2.0mmHg HDPE geomembrane (anti-seepage membrane) include physical properties, mechanical properties, chemical properties, thermal properties, and durability properties. Geomembranes place greater emphasis on their waterproof (anti-seepage) performance, deformation resistance, and durability in engineering applications. Numerous engineering practices have proven that geomembranes have excellent impermeability; Has good elastic strain capacity and can withstand different construction conditions and working stresses; It has good aging resistance, and the durability of geomembranes underwater and in soil is particularly outstanding. Our company produces geomembrane materials including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), and flexible ethylene vinyl acetate copolymer (EVA) geomembranes.

　　Our company produces 2.0mm HDPE geomembrane (anti-seepage film) with a thickness of 1 millimeter, a product width of 1-7 meters, and a length of 30 meters or 50 meters per roll. Product colors: black, white, blue, green, etc.

　　As altitude increases, air pressure decreases, and air density decreases, the oxygen content in each cubic meter of air gradually decreases. At an altitude of 3000 meters, it is equivalent to about 73% of sea level, about 62% to 65.4% at 4000 meters, about 59% at 5000 meters, and less than 52% above 6000 meters.

　　1、 The performance characteristics of 2.0mmHg HDPE geomembrane (anti-seepage membrane) are as follows:

　　1. It is a flexible waterproof material with a high anti-seepage coefficient (1 × 10-17 cm/s)

　　2. It has good heat and cold resistance, and its operating environment temperature is high at 110 ℃; Low temperature -70 ℃

　　3. It has excellent chemical stability and can resist corrosion from strong acids, alkalis, and oils, making it a good anti-corrosion material

　　4. It has high tensile strength, which enables it to meet the needs of high standard engineering projects

　　5. It has strong weather resistance, strong anti-aging performance, and can be exposed for a long time to maintain the original performance

　　6. It uses three separate feeders, and each layer of different ingredients can have unique properties, improving the engineering S performance of 2.0mmHg HDPE geomembrane.

　　7. Its overall performance, 2.0mmHg HDPE geomembrane (anti-seepage membrane) has strong tensile strength and elongation at break, making it suitable for use in various harsh geological and climatic conditions. Adapt to uneven geological settlement with strong strain force.

　　8. The 2.0mmHg HDPE geomembrane (anti-seepage film) produced by our company uses native plastic and carbon black particles without any preservatives. HDPE (high-density polyethylene) has been used in China to replace PVC as a raw material for food packaging bags and cling films. The 2.0mmHg HDPE geomembrane (anti-seepage film) produced by our company is non-toxic, has good engineering performance, and has a wide range of applications.

　　Under the alternating control of the west wind in winter and the southwest monsoon in summer, the dry season and rainy season in Xizang are very obvious, and the dry season is generally from October to April of the next year; The rainy season is from May to September, and the rainfall generally accounts for about 90% of the annual precipitation. The precipitation in different regions is also severely uneven, with annual precipitation gradually decreasing from 5000 millimeters in the southeast lowlands to 50 millimeters in the northwest.

　　There is a significant difference in climate between southern and northern Tibet. The southern Tibetan valley is influenced by warm and humid air currents from the Indian Ocean, with mild and rainy weather. The annual average temperature is 8 ℃, with low monthly average temperatures of -16 ℃ and high monthly average temperatures above 16 ℃. The northern Tibetan Plateau has a typical continental climate, with an annual average temperature below 0 ℃ and a freezing period of up to six months. The highest temperature in July does not exceed 10 ℃, and the months of June to August are relatively warm. The rainy season is characterized by frequent night rains, while the winter and spring seasons are characterized by strong winds. As far as the climate is concerned, it is appropriate to travel to Xizang from March to October, of which June to September is the best season.
