The simple way is to observe the appearance of the membrane without penetration.

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.

The selection of composite geomembrane should be considered from the fields of engineering application, economy, construction process characteristics and raw material characteristics.

Because the plastic geotextile in the construction process, the polymer high score guild starts from the first row in the direction of thermal extension, which enhances the bond between the branches and realizes the compressive strength to catch up.

When we choose farmland anti-seepage materials, we usually use relatively single anti-seepage materials such as rockfill and concrete. However, the choice of this material cannot achieve the effect of farmland anti-seepage work as expected, and its durability is relatively poor. However, in recent years, China has also made new developments in the development of impermeable materials, and a new impermeable composite material-waterproof geotextile has emerged.

The construction process of waterproof geotextile, the substrate must be firm, flat, clean, free of dust, greasy, wax, release agent, etc. and other debris; if there are pores, cracks, unequal defects on the base surface, it must be repaired with cement mortar in advance For smoothing,
