Culture Impermeable Membrane
Product Description
Culture Impermeable Membrane
Product Introduction：
The culture impermeable membrane has the characteristics of tensile resistance, impact resistance, tear resistance, strong strength, high hydrostatic pressure resistance, ultraviolet resistance, good impermeable water performance, etc., especially suitable for application in fish pond impermeable, shrimp pond impermeable, and aquaculture loach pond impermeable projects. Covering the whole fish and shrimp aquaculture bottom with culture impermeable film can separate the bottom of the pond from the water, which has a remarkable effect on the anti-seepage, virus pollution and anti-microbial erosion of the high-low shrimp pond. Because the culture impermeable film is smooth, it is not only convenient for disinfection and dredging, but also conducive to preventing the spread of pathogens at the bottom and shortening the time for cleaning the bottom of the shrimp pond and drying the pond.
Aquaculture Impervious Membrane Construction Scheme:
A. Personnel unrelated to laying shall not enter the construction site.
B. The method and equipment used for laying must not damage the impermeable film or its geotextile and substrate.
C. Construction personnel must wear shoes that do not damage the impermeable film during construction at the construction site.
D. There must be sufficient ballast or anchor to prevent the impermeable film from being blown up by the wind.
E. Anti-seepage film laying should be smooth, solid, as far as possible to reduce the fold, after laying in time ballast or anchorage.
F. Reasonable choice of laying direction, as far as possible to reduce the joint stress.
G. Reasonable layout of the position of each piece of material, and strive to have fewer joints.H. In the laying process to prevent any factor damage to the impermeable film, laying tools must not cause damage to the impermeable film.
I. There shall be no transverse joint on the slope with a slope greater than 10% within 1.5m of the slope foot.
