Seepage control membrane as impervious to plastic film substrate, and non-woven fabric composite geo impervious material, its seepage prevention of seepage control performance depends primarily on the plastic film. At present, the impervious plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene vinyl acetate copolymer), which is a kind of flexible materials for polymer chemistry, the proportion of small, extension of strong, high Adaptive deformation, corrosion resistance, low temperature resistance, good freeze resistance. Its main mechanism is to plastic film of not through water partition dam leaking channel, to its larger of tensile strength and extends rate bear hydraulic and adapted dam body deformation; and no spinning cloth also is a polymer short fiber chemical material, through acupuncture or hot stick forming, has high of tensile strength and extension, it and plastic film combined Hou, not only increases has plastic film of tensile strength and anti-puncture capacity, and due to no spinning cloth surface rough, increases has contact surface of friction coefficient, conducive to composite anti-infiltration film and the cover of stable. Also, they are good for bacteria and chemical corrosion resistance, acid, alkali and salt corrosion.

Aquatic farming film is with geo fabric and geo film composite and into of not permeable material, it main for anti-infiltration, and drainage and plus reinforced, aquatic farming film is divided into a cloth a film and two cloth a film, and width 4-6m, weight for 200-1500 g/m2, anti-pulled, and anti-tear, and items broken strong, physics performance indicators high, can meet water, and municipal, and building, and traffic, and Metro, and tunnel, civil engineering needs. Due to its use in the production of polymeric materials and adds anti-oxidant, it can be used in non-conventional humidity environment.

Features:

Light weight, good overall continuity, the construction is convenient.

High tensile strength, resistance to corrosion and good resistance to microbial attack.

Has excellent impermeability, flexibility and ability to adapt to deformations.

Good aging ability, underwater, the durability of composite geomembrane in the soil is particularly prominent.

Aquaculture construction method of membrane:

1. welding: welding machine, along the width of 10cm welding 1-2 welding, thick geomembrane for general application.

2. lap: a lap width greater than 20cm in the form of the following types of commonly used channel.

3. bond: the membrane adhesive materials, there are a wide variety of aquaculture products, generally less effective than welding, but can also meet the project needs.
