- Q:300 grams of geotextile how much money a square meter
- See the requirements of the data indicators in general about 2.4 Huazhi geotextile material manufacturers
- Q:What is the meaning of the geotextile What is its working principle
- Hot geotextile cloth is to isolate the heat and cover a layer of geotextile material. Advantages: light weight, the overall continuity is good, high tensile strength, corrosion resistance, anti-microbial erosion is good, easy construction. Non-woven geotextile properties: small pore diameter, good permeability, soft texture, and soil with a good combination. 2, construction (1) according to the embankment or base wide full section laying. (2) leave sufficient anchorage length on each side of the embankment or substrate. (3) To ensure integrity, when the lap method is continuous, the lap length should be 0.3 ~ 0.5m. When the seam is connected, the bond width is not less than 50mm. (4) site construction, material damage must be immediately repaired. Upper and lower seams should be alternately staggered, staggered length of not less than 0.5m. (5) try to avoid prolonged exposure.
- Q:Waterproof geotextile how much money per square meter
- This depends on the specifications and quality, the detailed explanation can see my user name
- Q:Some people say that geotextile is a chemical material of geotextiles, such remarks are a certain basis.
- Summer to sunscreen, winter to antifreeze. The So summer not only to be able to block the sun, but also breathable. The Winter to warm good. The To achieve such a request, no matter what you can make the material. The
- 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:What is the geotextile of polypropylene gb / t14800?
- GB / T-2017 Geosynthetics Static Crack Test (CBR Method) This standard specifies the method of measuring the breaking strength of geosynthetics by flat top pressing bar. This method is usually carried out on samples that specify the standard atmospheric humidity. This standard applies to all types of geosynthetics, but does not apply to materials with a pore size greater than 10mm.
- Q:Principle of drainage pipe geotextile
- Plastic blind ditch is made of plastic core wrapped filter cloth group type. Plastic core is a thermoplastic synthetic resin as the main raw material, after modification, in the hot-melt state, through the nozzle extrusion of fine plastic wire, and then through the molding device will be extruded plastic wire at the junction of welding , The formation of three-dimensional network structure. Plastic core with rectangular, hollow matrix, round and round shape of a variety of hollow. The material overcomes the shortcomings of the traditional blind ditch, with good surface opening rate, good water holding capacity, good porosity, good drainage, strong compressive strength, good pressure resistance, good flexibility, good soil deformation and good durability , Light weight, easy construction, workers labor intensity greatly reduced, high construction efficiency, which is generally welcomed by the Engineering Bureau, and has been widely used.
