Q:How to determine the soil moisture content?
To estimate the best water content of soil, and then from the best in order to two points each with two groups, the water content in turn decreased by about 2%.
Q:What need to pay attention to when choosing the imported geomembrane?
What needs to note are uniformity of the thickness, acid and alkali resistance, biodegradability, tensile stress limit and puncture strength.
Q:The pool of the soil, the loss and the number of lap
Lap 15 cm or so, more than 10% loss
Q:How to install the electrothermal film non-woven fabrics?
It can be laid on the floor with multi-group parallel connection method. Then install temperature control device, and plug in.
Q:What are the differences between PE geomembrane and PVC geomembrane?
PE geomembrane is made by processing ethylene raw material. PVC geomembrane is made by processing polyvinyl chloride raw material. Domestic projects nowadays all use the former one which is environmentally friendly, non-toxic, anti-aging, corrosion resistance, and strict national standards have been developed.
Q:How to use geosynthetics impervious device?
The geosynthetics impervious device is designed according to national standard of permeability coefficient. It is applied to test seepage resistance of all kinds of geosynthetics. It is convenient and practical with stable performance. Installation and use methods are as follows. 1. Set pressure. Press the set button "back" and the button ">" after powering on the device. Press the button “+”and“--”, then set pressure. After that press the button "back" to save it. After setting the lower limit value, press the set button to exit. 2. Clear the time setting. Redo the test and continue pressing the "--" button. The time value will be reset to 0 after 10 seconds. Don't press the button during the working time. 3. Check the time. Press the "--" button. The time value accurate to seconds will be shown on the screen. After 30 seconds, pressure value will be shown on the screen again. 4. Adjust to zero. If the pressure setting can't return to zero when the device is powered on without being applied pressure, you can press the reset button once. If the device is under pressure, release the pressure before pressing the button. 5. Open water injection cover plate. Add pure water until the water tank is full. Apply pressure and open pressure regulating valve to let water flow to chassis of high pressure cabin until the water begins to overflow. 6. Put the sample on the net plane of water collectormanifold smoothly. Let the excess water drain away to ensure that there are no bubbles in sample clamping device. Close the perforated plate and fix the sample evenly.
Q:Does Electrothermal membrane emit heating radiation?
But the effect of far infrared is 9.5 m far infrared radiation that it generates, such a wavelength is necessary for humans and all other living things, which can more easily produce resonance with people's skin and tissue and can penetrate into the depths of the skin and subcutaneous tissue, from and produce tepid effect, improve blood circulation, expand capillary, exclude microcirculation. Long-term exposure of radiation on the human body can improve blood circulation, dredge collaterals, promote metabolism, make the skin delicate, and resist aging. The electric heating film has been tested by the national far infrared detection center: The electric heating film product has good radiation performance, it is energy saving and electricity saving, does not contain harmful radiation to human body. The infrared wavelength it produces is 9.5 microns, which is not only harmless to the human body, but also beneficial.
Q:What is the construction method of the geotechnical membrane?
The construction method: To lay it in the range of measurement. To lay the composite geotechnical membrane before the first required to lay a good sand cushion on the roadbed, laying the width of the design requirements set. When laying, do not allow the laying of folds, as far as possible to tighten. After the pavement, the U type nails or bamboo nails is used to fix. When laying composite geotechnical membrane, the surface of the sand layer is smooth, no hard protrusion, and timely fill sand cover, avoid direct exposure to the sun for a long time. When the composite earthwork film is laid, the length of the transverse lap and the longitudinal lap can meet the design requirements. After the composite geotechnical membrane is rolled out, the filling material is filled up in time, and after the soil is covered with light compaction mechanical compaction, only when the thickness of the overburden layer is larger than 0.6m, the soil can be compacted by heavy compaction machine. Composite geotechnical membrane according to the design requirements can be divided into two types of longitudinal force and lateral force, the laying of composite soil before the film to understand the design intent, strictly according to the design requirements of the laying.
Q:Should the protective film of the refrigerator be torn off?
So its protective film should be torn off. Protective film plays the function of protecting the appearance of the refrigerator. A new refrigerator is packaged with a large plastic bag in the carton, which can make sure that its protective film can be maintained in good condition and easily torn off. But when the refrigerator is unwrapped and put into normal use, the protective film in the air may dry out after a long time. And after a few years, the film will become brittle and tightly attached to the surface of the refrigerator, and produce crack for environmental reasons, which will affect the beauty of the refrigerator and make it very difficult to tear off the protective film. Therefore, the protective film should be torn off soon after the refrigerator is unwrapped.
Q:Geomembrane classification
Seen from the naked eye, particulate is because the feed back material is added too much. Secondly, take samples of the material on site and sent to relevant national authorities to be tested, while adding too much back material will cause the HDPE membrane not reaching American standard index, indicating that the material is not very good, but one thing you can see, as well as some granular things, sand holes on the membrane, which is difficult to distinguish
