Development Prospects and Laying Knowledge of Composite Geomembrane

Our company has been engaged in the sales of composite geomembrane for many years, and has received unanimous praise from customers in the industry. Let us explain the specific laying knowledge of composite geomembrane in large-scale engineering applications.

First, the general characteristics of composite HDPE geomembrane for sale include physical properties, mechanical properties, chemical properties, thermal properties and durability. In the application of composite geomembrane engineering, more attention is paid to the waterproof and anti-change ability and durability. A large number of engineering practices have shown that the composite geomembrane has good aging resistance, good elasticity and ability to adapt to deformation, and can withstand different construction conditions and working stress. With good aging resistance, it is underwater and in the soil. The durability of composite geomembrane is particularly outstanding. In short, the composite geomembrane has very outstanding anti-seepage and waterproof performance.

The characteristics of composite geomembrane vary greatly with its type, manufacturing method and product type. The main mechanism of composite geomembrane is to block the leakage channel of earth dam by impermeable plastic film, with its large tensile strength and elongation to withstand water pressure and adapt to deformation of dam body; and non-woven fabric is also a polymer Fibrous chemical materials have high tensile strength and elongation through needle punching or hot bonding. After combining with plastic film, it not only increases the tensile strength and puncture resistance of plastic film, but also because of the non-woven fabric The rough surface increases the friction coefficient of the contact surface, which is beneficial to the stability of the composite composite geomembrane and the protective layer. At the same time, they have good corrosion resistance to bacteria and chemical action, are not afraid of acid, alkali and salt erosion, and have a long service life under the condition of avoiding light.

The production and application of composite geomembrane in China is mainly concentrated in the North China area, and relatively few. At present, the central government’s strategy for the large-scale development of the western region has started, and geosynthetics have shown more excellent functions in flood control, emergency rescue, water collection and irrigation, and environmental protection. The composite environmental geomembrane for sale (composite impervious membrane) is divided into one cloth, one membrane and two cloths and one membrane, with a width of 4-6m and a weight of 200-1500g / m2. It has high physical and mechanical properties such as tensile, tear resistance and bursting. The product has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering in water conservancy, municipal administration, construction, transportation, subway, tunnel, engineering construction, such as seepage prevention, isolation, reinforcement, crack prevention and reinforcement. Because it uses polymer materials and anti-aging agents are added to the production process, it can be used in unconventional temperature environments. Commonly used in anti-seepage treatment of dams, drainage ditches, and anti-fouling treatment in waste plants.

Possibly water and buildings. For example, to solve the water problem during construction, it is necessary to prevent water loss. This must solve the problem of seepage prevention. The use of geomembrane is the most cost-effective method. In addition, the Yangtze River and the Yellow River are inseparable from geotechnical materials for flood control and flood control projects. The restoration of the Yangtze River embankment is mainly composed of geosynthetics. Sand fixation and greening, soil desertification in Northwest China is becoming more and more serious. The use of composite geomembrane for sand fixation and desert greening is a major measure to control wind and sand in China. Therefore, the majority of manufacturers should seize the current favorable opportunity to find business opportunities:

1. National leaders and leaders of all relevant departments attach great importance to the application of the new material, new process, and new technology of composite textured geomembrane for sale, and increase efforts to promote new technology and adopt new materials. At present, relevant departments are actively working on the scientific and orderly organization of the production of geosynthetics.

2. Increased national investment in construction, and expanded the market for geosynthetics.

3. China has initially formulated various norms and standards. Testing technology and theoretical research have developed a lot, and testing institutions have been established to standardize the production and application of geosynthetics. The National Development and Reform Commission is responsible for organizing and establishing 10 demonstration projects, of which: 4 projects by the Ministry of Water Resources, 4 projects by the Ministry of Communications, 1 project by the Ministry of Railways, and 1 project by the Ministry of Construction. In addition, the Ministry of Water Resources has also established 50 demonstration projects. At present, the demonstration projects have been checked and accepted, so that the popularization and application of geosynthetics has a model and scientific basis. Therefore, composite geomembrane is a very new type of geotechnical engineering material. Its economic and social benefits are very significant, and it has a high value for promotion and application.
