FAQ

A geomembrane is a synthetic material used in civil engineering and environmental applications to provide a barrier against the seepage or leakage of liquids or gases. It is typically made of flexible plastic sheets, such as polyethylene or PVC, and is used in landfills, mining operations, reservoirs, and other containment systems to prevent the migration of potentially harmful substances.

Installation steps of the electrothermal?film non-woven fabrics? Ground leveling first; the first layer: Extruded sheets should be paved on the top of the ground leveling layer; the second layer: Pave floor heating special thermal insulation reflective film; the third layer: Pave electrothermal?film imported from South Korea ; the fourth and fifth layer: Pave two-layer waterproof cloth or non-woven fabric; the sixth layer: Cement pressure plates or a protective plates are paved in the interlayer of the waterproof layers so as to protect electrothermal?film; the seventh layer: Drill 2 to 3 cm cement layer; the eighth layer: Pave floor tile or floor.

make preparation for the test the workpiece; insert the probe plug into the computer's probe socket; power equipment; determine whether need to calibrate the instrument. If in the needs, choose the appropriate calibration method to calibrate; measurement. The vertical probe contacts the workpiece test surface and gently press the probe loading units, when the probe is in contact with the measured surface stability, with a loud beep, the screen will display the measurement identification and measurement. If the measurement is not identified or no flashing logo, it indicates that the measurement probe is unstable. After remove the probe, measuring identification disappear, thickness values ??remains. turn off the instrument. note! If the measuring head is placed instablely in the measurement, it will cause the measured value and the actual value have large deviation; if appropriate calibration has been carried out, all measured values ??will be kept within a certain range of error (see Appendix 1); according to statistics point of view, the once readings are not reliable. so any measured value of the instrument is five times; the unseen; the average value of the measurement. The five measurements are completed within a fraction of a second by the probe and instrument; to make measurements more accurate, multiple measurements at one point can be used, and calculate the average value as the final result of the measurement; after knowing the measurement results, be sure to lift the probe from the workpiece to 10mm or more, we can go for the next measurement.

First, you should have a bottle of cleaning fluid, which is commonly known as Philips oil, its market price is around 10 dollars, and is also known as 530. The other is a surgical blade about three dollars. In addition, you should do a hanging tool which is made by the left-off mobile phone card sleeve, and several dust-free cloth. The last one is a mobile phone film, which depends on how much you want, the different size and grade level, the wholesale price is very cheap. It can be brought at the local large mobile phone market. It is estimated that the total cost is less than 100 dollars

Yes, it is. 1. The gardness of iPhone glass is larger than fingernails and metals like keys, so these things scratch it. 2. Many components in dust and sand wind, such as quartz, is harder than the glass. For example, if some grains of sand containing quartz in your hand, they will cause permanent scratches to the iPhone glass. 3. In terms of the service time, the mobile phone is a durable product, but after 2 or 3 years, you will buy a new one. 4. Therefore, if you use it carefully and do not mind scratches, you need not to stick film, otherwise you had better stick film.

Geomembranes can contribute to the preservation of endangered species by creating protective barriers that prevent contamination of their habitats. These impermeable liners are often used in landfills or waste containment facilities to prevent leakage of harmful substances into the environment, helping to maintain the quality of water sources, soil, and air. By ensuring the integrity of ecosystems, geomembranes indirectly support the survival and well-being of endangered species by safeguarding their habitats from pollution and degradation.
Yes, geomembranes can be used in agricultural applications. They are commonly used as liners for irrigation ponds, storage tanks, and canals to prevent water seepage and improve water management. They can also be used as covers for manure storage facilities to control odors and reduce contamination. Additionally, geomembranes can be utilized to line agricultural waste containment areas, helping to protect the environment by preventing the leaching of harmful substances into the soil and groundwater.
