How to Install a Pond Liner---Installation Guide

The fish/shrimp farm pond liner is a new type of membrane with polyethylene as the main raw material, with double resistance (anti-ultraviolet, anti-aging ingredients), which greatly prolongs the service life. 0.4-0.5 mm is the general specification of fish pond liners. As long as it is used properly, the underground service life can reach more than 20 years, the exposed part of the slope can be used for more than 10 years, and the exposed part of the slope can also be covered with geotextiles, and the service life will be longer....

Recently, the HDPE geomembrane produced by Gerui Geosynthetic Co., Ltd. was urgently transported to the disease control and epidemic prevention hospitals in Hong Kong

Recently, the HDPE geomembrane produced by Gerui Geosynthetic Co., Ltd. was urgently transported to the disease control and epidemic prevention hospitals in Hong Kong, Guangdong, Zhejiang, Hainan and other places, and was applied to the emergency seepage prevention project of the prevention and control hospital. The construction of projects will help win the battle against epidemic prevention and control....

How to do Pond Liner Leak Sealer Repair?

If the depth is deeper than 2 meters, the water pressure is too high, we need to use an extrusion welding gun to weld, first take a geomembrane with a diameter larger than 5 cm of the hole, then heat the surrounding of the hole and this piece of membrane, and then put the piece of film Adhere to the hole until cool. Of course, stickers can also be used for bonding, which can be operated when conditions permit....

How to Test the Welding Seam of Anti-seepage Geomembrane Testing Project?

When welding, the overlap between the anti-seepage membranes should not be less than 10 cm. At the same time, reducing the welding seam as much as possible can save the cost of materials and improve the stability of the anti-seepage system. Generally, there are two ways to detect the welding seam: the first is to use the air pump, the pressure gauge and the hollow needle to detect; the second method is to use the vacuum pump to detect. The first method requires inserting a hollow needle into the welding seam to pressurize the entire welding seam and block the two edges of the welding seam, and then detect the change of air pressure. The second method does not require damage to the impermeable membrane. Apply soap liquid to press the vacuum pump to pressurize the soap liquid, and detect the change of airtight air pressure in the welding seam. The air pressure of the air pump can reach and maintain 250KPA within 2 minutes, and then observe for 10 minutes. The allowable air pressure reduction range is 10KPA. If the drop is greater than 10KPA, the welding is unqualified, and it needs to be repeated more than ten times....

How to Distinguish American Standard ASTM Geomembrane

Geomembrane is divided into many standards according to the materials and production process. Among them, American standard geomembrane is often used in anti-seepage projects with relatively high requirements, so how to distinguish whether the geomembrane is American standard geomembrane? American standard geomembrane production requires high-standard raw materials and production equipment, almost all of which are produced by blow molding process. Because the blow molding process product index is higher!...

How to Distinguish Different Types of Geomembrane

Geomembrane is one of the important materials of waterproof membrane at present, which can be divided into low density polyethylene geomembrane, high density polyethylene geomembrane and linear polyethylene geomembrane. Here's how to differentiate these types of polyethylene geomembranes:...

Construction Points of HDPE Geomembrane

Trial welding shall be performed on HDPE geomembrane specimens and under the same membrane surface and environmental conditions as production welding; experimental welding requires inspection and adjustment of welding equipment; welding equipment and welding personnel are only required to successfully complete the experimental welding Only then can productive welding be performed....
