Product Description

 

Product Description

1, Composite geomembrane raw materials
Composite geosynthetic membrane is a geosynthetic anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film.
The plastic films used for anti-seepage applications both domestically and internationally mainly include polyvinyl chloride (PVC), polyethylene (HDPE, LDPE, LLDPE), and ethylene/vinyl acetate copolymer (EVA). They are polymer chemical flexible materials with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance

2, Design of Composite Geomembrane Engineering
Select appropriate types and specifications based on the nature, category, application location, usage conditions, design requirements, etc. of the project.
Determine the thickness of the geomembrane based on the required water pressure strength in engineering design, as well as application conditions such as exposure, burial pressure, climate, and service life.
Based on the actual size, area, construction conditions, and construction capacity of the project, the width and length of the geomembrane are determined with the principle of minimizing joints during construction.
When the base layer is a concrete structure, it is advisable to choose a long filament non-woven composite soil film that can be directly bonded to the cement base layer.
In the application of anti-seepage treatment in highways, the lower part of the central median is generally treated with a cloth and a film of 200-300g/m.

3, Types of composite geomembrane
Composite geotextile can be called composite geotextile by using non-woven geotextile, woven geotextile, or machine woven geotextile to composite with polyethylene, and directly coating with thermal lamination or polyethylene PE film (in addition, composite waterproof boards made of EVA material can also be called composite geotextile, and are widely used in highway and railway tunnel projects). Composite geotextile and composite geomembrane may have different names, but they refer to the same products. Due to the lack of standardized names for geotextiles, which are emerging materials, the definition of geotextiles is confusing and non-standard. India is developing jute geotextile - strictly speaking, all membrane like materials used in civil engineering can be collectively referred to as geotextiles. Composite geotextiles are geotextiles that combine or connect two materials together to use composite materials with isolation and anti-seepage effects.

4, Production process of composite geomembrane
Simply put, it is the process of making plastic particles into a plastic film through the method of coating, which becomes a geotextile, also known as a waterproof board (depending on the thickness of the geotextile). Due to the use of geotextile (woven fabric or plastic woven fabric) as the base fabric, composite geomembrane not only has the functions of geotechnical isolation, drainage, reinforcement, and protection, but also has the function of sealing (anti-seepage). It can be widely used in many fields such as water conservancy dams, road construction, airports, drainage, housing, environmental protection, etc. In engineering, it mainly plays a role in anti-seepage, protection, reinforcement, etc.
