Currently enterprises to participate in the drafting of the revised national standards for geosynthetics have six. This year there are two new enterprise products through scientific and technological achievements. Contribution rate of scientific and technological innovation of enterprises reached more than 70%. In the first half of this year, the Ministry of enterprise technology research with a half time success PDL CRTSIII type ballastless sliding layer of new products to the sliding performance, reduce rail vibration, easy construction, extension of life and other characteristics, production on a lead to more than 3000 million orders, also apply to the State of New Railway Datong - Xi'an line construction. Geomembrane impervious projects in specific application :: As technology advances and technological strength, more and more geotextile material is applied to people's daily life and learning to become a good help to pave the way for economic development, Geomembrane is not only a major highlight of the building materials market in a wide range of technical updates is a lot to contribute. Support layer requirements: It is natural conditions and the selected base geomembrane material selection, usually well-graded soil compaction, particle size according to the thickness of choice. Reference data: for 0.2mm thick geomembrane support layer should be less than the maximum diameter of 6mm, uniformity coefficient should be not less than 20. We always adhere to "grasp the quality of PE geomembrane image outside" corporate policy, strictly in accordance with national standards of ISO9000 quality management system of production, to ensure stable and reliable product quality and performance, and the formation of a series of perfect service.
