According to a report by Hong Kong’s “Eastern Network†on April 14, researchers from Eindhoven University of Technology in the Netherlands have recently developed an environmentally-friendly electric vehicle that can degrade 90% of its components.
The electric car has two seats, and most of the components such as the body, structural parts, and interior decoration are made of biodegradable plastic polylactic acid and hemp fiber composite materials, which are made from sugar cane. Researchers assembled composite sheets to make structural components such as chassis and frames for cars. Paints also use materials that have less environmental impact. It is alleged that more than 90% of parts can be broken down if the car is buried in the soil.
In addition, the car's complex shape of the curved parts using 3D printing technology, and the important parts of the vehicle using a honeycomb structure, and steel and ordinary plastic similar strength and stability, while reducing weight. The body weighs only 350 kilograms and is less than half the weight of a light car. The car has a top speed of about 100 kilometers and a maximum driving distance of 240 kilometers. It is suitable for use in the city.
Eindhoven University of Technology has so far produced four electric vehicles that use biodegradable materials. They are also working hard to improve the use of this material. The researchers plan to obtain the license required for driving on the general roads before the summer and try out the cars in major European cities.
HDPE Smooth Geomembrane is one double-surface membrane with flat and smooth appearance made from virgin resin with special formula. We can produce Hdpe Geomembrane, LLDPE Geomembrane, LDPE geomembrane etc. HDPE glossy geomembrane has excellent impermeable and antifouling property and mechanical property; dimensional stability, chemical stability, thermal resistance and aging resistance are good; in the meantime, it also has excellent resistance to UV radiation.
The Application of HDPE geomembrane
1) Environmental protection sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .
2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).
3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).
4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).
5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).
6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.)
