Hdpe film why not in winter construction
HDPE geomembrane in the specified ambient temperature can be constructed, because of its own good cold resistance, the use of ambient temperature is high temperature 110 ℃; low temperature -70 ℃. Mainly in the seams must be handled well, because the winter is relatively dry, the current construction, HDPE geomembrane seams with impermeable geomembrane hot melt welding, film thickness, temperature, wind, humidity, voltage, cushion Flatness and many other factors, its strength and sealing effect is also difficult to guarantee, especially 0.2mm and below the geomembrane and impervious geomembrane welding quality is very poor. But do the relevant technical guidance, you can ensure that the product impermeability, play a very good anti-seepage effect. HDPE geomembrane winter construction Notes: 1. Temperature should generally be above 5 degrees Celsius, low temperature geomembrane should be more nervous, high temperature geomembrane should be relaxed. 2. The wind is below four. 3. When the temperature is too low, more than 4 winds and rain and snow weather should not be general construction. 4. Windy weather, wind impact geomembrane construction, to be welded HDPE geomembrane application sand bag pressure firmly.
Minus 5 degrees above can be, I professional production geomembrane
Geomembrane is hot-melt welding connection, geomembrane impermeable construction is mainly in accordance with the design and site conditions using hot melt welding machine to cut the membrane coil welding. Less than 4 degrees, the impact of welding, the temperature is too low welding difficulties, the general welding temperature is 400 degrees, the ambient temperature is too low to heat the film to 400 degrees difficult, too much heating can cause film heat damage, so 4 degrees or more Ambient temperature is appropriate. Winter in the winter when the ambient temperature below zero, not easy to geomembrane welding construction.
