It has excellent impermeability performance, and its impermeability coefficient is much better than that of conventional waterproof materials, which can effectively block water penetration and steam diffusion. It has balanced mechanical strength, with a tensile strength at break of up to 28MPa and an elongation at break of up to 700%. It has excellent elasticity and deformation capacity, is suitable for expanding or contracting base surfaces, and can effectively overcome the problem of uneven settlement of the base surface. It has strong chemical stability, is resistant to high and low temperatures, asphalt, oil, tar and other pollutants, and has outstanding UV resistance and decomposition resistance. It can be used exposed without additional protection. It is environmentally friendly and non-toxic, with no harmful substances added during the production process. The impermeability principle is physical barrier, with no chemical changes, meeting the environmental protection requirements of drinking water pools, aquaculture ponds, etc.
The thickness ranges from 0.2mm to 3.0mm, and the conventional specifications are 0.5mm, 0.75mm, 1.0mm, 1.5mm; the width ranges from 1m to 8m, and customized widths are supported. The length can be cut according to engineering needs, and it is divided into two grades: GH-1 and GH-2 according to the national standard GB/T17643-1998. The dimensional stability is ≤±3%, and the low-temperature impact embrittlement performance at -70℃ passes the test. It has good welding performance, the joint overlap width is not less than 10cm, and the weld strength is high. The product is in the form of continuous rolls, which is convenient for transportation and laying. The weight of a single roll varies according to the thickness and width, usually between 50kg and 200kg, which can meet the handling needs of different construction scenarios.
In the agricultural field, it is widely used for the impermeable treatment of reservoirs, drinking water pools and water storage ponds, as well as the anti-leakage transformation of irrigation systems. It is also suitable for the waterproof and anti-corrosion of breeding supporting facilities such as pig farm septic tanks and biogas digesters. In the aquaculture industry, it is used as the lining material for intensive and industrialized aquaculture ponds, fish ponds and shrimp ponds, as well as the slope protection and waterproofing of sea cucumber circles. It can effectively isolate the pond bottom from the water body and improve the aquaculture environment. In environmental protection projects, it is applied to the impermeability of domestic waste landfills, regulating ponds of sewage treatment plants and hospital solid waste disposal sites to prevent the spread of pollutants. In addition, it is used for the lining of artificial lakes, rivers and golf course ponds in gardens, the impermeability of oil storage tanks in the petrochemical industry, the lining of chemical reaction pools, and the foundation reinforcement and culvert impermeability in transportation facilities.
