Product quality inspection of composite geomembrane materials.

In the design of roof waterproof structure, due to the consideration of structural deformation, temperature deformation, shrinkage deformation, vibration and other influencing factors, it is necessary to take the key to deformable parts such as deformation joints, partition joints, roof ridges, cornices, gutters, water downs, entrances and exits. An additional reinforcement layer is provided on the site.

Sew knit polyester cloth before application and waterproof layer, should check the current status of the roof at the grass-roots level to ensure that the roof with no moisture, no freezing, smooth and clean, no loose grain protrusion, even other blocking some impurities, waterproof system of the cohesive force for don't need the waterproof work must carry on the protection of areas, use brush, broom to clean up the surface dust, Or other loose attachment, for the corner, gap joints, water outlet, out of the pipeline need to apply waterproof system, the need for separate treatment work in advance, the use of a layer of basic coating to add appropriate size of stitched polyester cloth to add a layer of basic coating, Next, I will talk to you about the construction process of sewing polyester cloth to help you have a deeper understanding of sewing polyester cloth.

The placement process of HDPE geomembrane includes material cutting, test welding, welding equipment debugging, anchoring, inspection and acceptance, etc.

As we all know, the main equipment for producing geomembrane in my country is divided into laminating machine and blown film machine. Of course, the equipment is getting more and more advanced, and the produced geomembrane has been greatly improved in terms of vision and physical chemistry. So, how are the blue and green impermeable geomembrane processed? In theory, in actual design, users usually design with black and green on the other side or blue on the other side. In addition, when the two sides are colored, they are used for special projects. It is called black green and black blue. If you simply produce reverse osmosis membranes with the same color on both sides, you can make a laminating machine. When producing black-green or black-blue impermeable membranes, blow molding equipment is required for processing. Special masterbatch materials and ultraviolet strong carbon black are added in the production process, which has excellent durability.

A one-kilometer-long diversion canal with an impermeable geomembrane was built. After tests, the head of the canal drained 1000m3, and only 50m3 was lost at the canal end. 950m3 of water can be directly used for farmland irrigation.
