Q:How to judge the geotextile test results are reliable
Different methods, different detection methods will lead to different results. But you can get the authority of the provincial inspection hall, do the test report
Q:Acupuncture geotextile is divided into several kinds of how is it used?
Acupuncture geotextile is now divided into two types, according to the fiber form to points. Continuous fiber called filament acupuncture non-woven geotextile. A few centimeters of length fibers made of staple fibers for nonwoven geotextiles. Use is not used, mainly used in geotechnical engineering in the filter, isolation, drainage and so on.
Q:200g geotextile how much money a square
Geotextile laying - including the labor costs (according to geotextile specifications and laying conditions and requirements are different), material costs (specific quality requirements and thickness, are not the same ..), mechanical use costs (such as transport, sewing System, hoisting, etc.). The price is different. Sometimes the construction of our geotextile laying, the price per square meter from 9 yuan to 50 yuan range.
Q:What causes the geotextile aging phenomenon
Gundam has the characteristics of the product we are all obvious, both in the highway, dams, railways and many other occasions have a very strong product features, and the performance is very outstanding, geotextile is an irreplaceable geotechnical material. Although the geotextile has unparalleled advantages, but the product is not perfect that any product has more or less problems or less, geotextile is the same, its aging problem has been with us, then in the end what causes Geotextile aging? Geotextile aging problem refers to the geotextile in the sun by the smell, temperature changes, biological erosion, chemical corrosion, moisture and other external factors, so that the geotextile strength and performance gradually weakened, loss of seepage effect. UV radiation intensity changes with the intensity of solar radiation, geotextile aging speed with the intensity of UV radiation and speed. Synthetic polymer polymer is concerned, the sun radiation is the main factor in the degradation of polymer degradation. UV radiation in the sun is the most important factor in the aging of the fabric. The ultraviolet radiation causes the polymer to produce a photooxidative decomposition reaction, especially ultraviolet light at a wavelength of 290 to 400 mPm, which has a significant decomposition effect on the polymer , Because the geotextile in the range of ultraviolet light energy is higher than the polymer chemical steamed broken the required energy, so the polymer material aging is very obvious.
Q:Geotextile laying on the requirements of grass - roots materials
No special requirements, mainly from the role of filtering, over the water, but I, specializing in the production of geotextile, geomembrane, wish smooth
Q:Why lay the geotextile cloth after the gravel cushion
This is to prevent the soil from slipping away
Q:Geotextile business how to run
Geotextile as a geotextile material, engineering applications have been very popular, the market competition is also very intense. Profits have been very low Bulk geotextile transactions are mainly ordered in the form of tender, so please pay attention to bidding information, I wish you success.
Q:Planting roofing geotextile lap way
Lap 10 cm, sewing with sewing machine, I specializing in the production of roofing with geotextile, drainage board and other products, wish smooth
Q:Geotextile cost how much money a flat
Geotextile laying - including the labor costs (according to geotextile specifications and laying conditions and requirements are different), material costs (specific quality requirements and thickness, are not the same ..), mechanical use costs (such as transport, sewing System, hoisting, etc.). The price is different. Sometimes the construction of our geotextile laying, the price per square meter from 9 yuan to 50 yuan range.
