The key factors of geotextile aging and toughness

Temperature is a key factor in sensitizing aging and toughness. The use of humidity to break branched polymers is explained in two ways: First, it is directly destroyed in view of temperature changes. Due to the tropical zone, fabric fibers can melt, and temperature changes cause changes in the branch structure of the polymer and change the fabric function. Secondly, in view of temperature changes, the deterioration process caused by cables in other countries can be accelerated. Filament aging cloth has many aging elements, and there are many external elements, such as the outer layer of high quality gravel geocell, and the premise of using filament. The use of parts and steps should be relevant to the overall situation and should be analyzed. The practical application of silk-like silk cloth is mainly aimed at the use of geotextile [process implementation], field sampling test, familiar with the aging degree of the fabric during use. In addition, the samples can be placed at the same time during the construction process, and a sampling test should be conducted at the segmentation stage of the engineering operation process to understand the aging degree of the fabric. How to remove stains on geotextile? The manufacturer did not pay attention to the production or preservation of geotextiles, resulting in some stains on the geotextiles. If the stain of the geotextile is not removed in time, it may affect the use of the wholesale plastic geocells. Therefore, when there are stains on the geotextile, we must take measures to remove them. The manufacturer produces a new material geosynthetics. When the stain is too heavy, use a neutral lotion or toothpaste to improve the brightness and brightness after cleaning the surface. When the surface of the dirt cleaning cloth is soiled, a special cleaner for the furniture is wiped off after the manufacturer removes the stain. In order to improve the smoothness of the geotextile, you can wipe it with a soft cotton cloth after cleaning the surface, and it is easy to scratch the surface with the hard part. Be careful not to immerse the neutralizer or cloth on the surface of the plastic geocells factory price, otherwise it will be immersed on the surface. According to engineering needs and specific construction requirements, detailed test reports will be issued. The tensile properties under different negative temperature environments are indeed affected by the water content, and the rate of reduction of the manufacturer's elongation is gradually weakened by the negative temperature. Within the coefficient range, make full use of the tensile properties of short-fiber needle-punched geotextiles. These are all ways to quickly remove stains from geotextiles. I hope you don't think you can leave stains on the geotextile.

Matters needing attention in the construction of composite geomembrane

The following are the construction considerations for composite high quality gravel geocell (1) Use must be embedded: the thickness of the cover should not be less than 30cm. (2) The renovated anti-seepage system should be composed of cushion layer, anti-seepage layer, transition layer and protective layer. (3) The soil should be firm to avoid uneven settlement and cracks, and the turf and tree roots within the impermeable area of ​​the wholesale plastic geocells should be removed. Lay small-diameter sand or clay as the protective layer on the contact surface with the membrane. (4) When laying, the geomembrane should not be pulled too tightly. It is better to bury the soil at both ends into a corrugated shape. Especially when anchoring with rigid materials, a certain amount of expansion and contraction should be left. (5) During construction, stones should be avoided, and heavy objects should be directly hit on the plastic geocells factory price. It is best to construct, lay the membrane, and cover the protective layer during construction.
