Japan has been particularly sensitive to the use of rare earth metals for electric and hybrid electric motors because Japan does not have a source of such materials and must import them from other countries, especially China. Therefore, Japanese researchers have been trying hard to find a substitute or method.
At the TECHNOFRONTIER trade show in Tokyo in 2011, the research team demonstrated their new motor, the same size as the Toyota Prius. The team also admitted that the motor is currently not very energy-efficient, there are also obvious noise and vibration, but they believe that further research will lead to more competitive breakthroughs.
The silicon tube is a kind of new composite pipe with silica gel solid lubricant.The main raw materials are high-density polyethylene and the core layer is the lowest friction coefficient of the solid lubricant silica gel.Widely used in optical cable communication network system.
Performance characteristics of silicon - core tube
1. The silicon core layer of the inner wall is solid, permanent lubricant, the friction property of the inner wall of the silicon core remains unchanged, and the cable can be repeatedly drawn in the pipe;
2, its inner wall of the silicon core layer is pressed by synchronization in high density polyethylene pipe wall, and evenly distributed throughout the pipe wall, the wall of the silicon core layer and high density polyethylene with the same physical and mechanical properties, not peeling off, out of, and silicon tube with life;
3. The silicon core layer of the inner wall does not react with water, and the pipe can be flushed after the accident.
4. The radius of curvature of silicon tube is small (10 times of its outer diameter).When the tube is in the bend and the gap, it can be determined according to the environment, without any treatment, no need to make a transition;
5. The length of each (disk) silicon tube can be made to any length.In general, the standard length of each (disk) silicon tube is 2000 meters in terms of the convenience of transportation safety and construction.
6. The construction is convenient and the project cost is reduced.The silicone tube is not required to coat the tube, and it can be used directly in the pipe line, without the tube.Since the length of the silicon tube is generally 2,000 meters, the well can be set up every 1,000 meters, and it will only take 15 minutes for each 1000 meters.
Product appearance
High density polyethylene (HDPE) silicon inner and outer walls should be clean and smooth, not allowed to have bubbles, obvious scratches, dents, impurities, color inequity defects.Pipe ends shall be cut flat and perpendicular to the tube axis.The inner wall of silicon core should be tightly welded and no deform phenomenon.The outer wall of the pipe is clearly marked.
Application fields: outdoor communication cable and cable pipeline system, public information network, public transport system, cable network and highway communication engineering construction.
