Does computer vision protective film really work?
- It is for sure that the protective film has no effect, and will make the screen looks dark, impacting eyesight! Because present display is plated with a layer of anti-dazzle film on the surface, which has radiation protection fuction, basically can guarantee vision health of users. Of course, if watch the screen before the computer for a long time, it only does harm to the vision without any benefit, so it is recommended to reasonably arrange time and not always sit in front of the computer.s
High density polyethylene root-resistant geomembrane
- High density polyvinyl chloride root puncture resistant geomembrane, aslo called high density PVC root resistant membrane, is a kind of geomembrane which has good seepage-proof effect and good resistance to puncture as well. High density PVC root resistant membrane, with good flexibility and puncture resistance, can be used in a variety of complex construction environment. The width of common High density PVC root resistant membrane in current market is 2m. You can use dedicated welding machine when paving a large area of high density PVC root resistant membrane. Besides, the high density polyethylene root puncture resistant geomembrane in market is also called HDPE root resistant membrane which has better anti-seepage effect, anti-puncture ability and longer service life than High density polyvinyl chloride root puncture resistant geomembrane. It is also cheaper than High density polyvinyl chloride root puncture resistant geomembrane so it can completely replace High density polyvinyl chloride root puncture resistant geomembrane. The width of high density polyethylene root acupuncture resistant geomembrane in current market is 8m, which the common width is 6m. Compared with High density polyvinyl chloride root puncture resistant geomembrane, it can reduce welding cost in construction greatly.s
Imported geomembrane imported anti seepage film width.
- Geomembrane is generally six meters wide. it can be up to 8 meters.s
How to measure the thickness of the paint film?
- The agnetic thickness measurement method can be used to measure the magnetic metal matrix: The thickness of the non magnetic coatings on steel, iron and nickel: Zinc, chromium, paint, electrophoresis, enamel, rubber, powder, enamel, coating, etc.) B. To use the eddy current thickness measuring method and nondestructive measurement of non magnetic metal (such as: Aluminum, copper, stainless steel) on non conductive coating thickness (such as: paint, powder, plastic, rubber, enamel, enamel, coating, etc.)s

How many specifications of seepage-proof geomembranes are there in the market?
- The thickness of HDPE geomembranes can be 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5mm and so on. In accordance with the national standard of CJ/T234-2006, and from the actual situation, the recommended thickness of the HDPE membranes should be no less than 1.5 mm at least, and be within the error of plus or minus 3%. According to my previous experience, the thickness of 1.5 mm and 2.0 mm are often used in landfill sites. Of course, geomembranes with different thickness are used in the different parts of landfill sites, which can mainly be used for the seepage-proof control of substrates, side slopes, and closure covers. Different membranes are used in different parts of the landfill sites, such as smooth membranes are used in substrates, rough membranes are used in slopes. In addition, the choices of thickness are influenced by many other factors, such as the terrain, soil, impervious materials, impervious requirements of landfill sites and so on.s
