In earthquakes, after a severe earthquake, there will be house collapses, mountain torrents, and mudslides. What's more dangerous is that there are aftershocks after the earthquake. The aftershocks are hidden in Yaoyao’s rocks and buildings. Push hands in the dark. Rescue workers blindly enter the disaster area and are easily in trouble. For this reason, it is necessary to carry out investigations in advance. So what is the approach?
Drones now have practical applications in many areas, including viewing enemy's valuable data in wars or viewing specific disasters in the affected areas. However, although drones have been widely used, there seems to be a big limitation, that is, they cannot detect the inside of a building and they cannot advance on rugged road models.
However, CyPhy's latest drone product seems to find a perfect balance between these two points. Recently, CyPhy signed a cooperation agreement with the U.S. Air Force. The U.S. military has created a mini-drone weighing only 80 grams for the U.S. military. It is not only very compact, but also can fly for a long time and can send back up to as long as possible. Two hours of HD video. At the same time, this drone can wirelessly charge and transmit data within a range of 76 meters. In practical applications, soldiers do not need to carry bulky charging equipment to charge the drone from time to time. At the same time, this feature also increases the reliability and safety of the drone and does not interfere with wireless signals.
Although the cooperation between CyPhy and the U.S. military means that it will be possible in the future to appear on the actual battlefield and to help soldiers view the dangerous situation in front of them, the combat investigation should only be part of the practical application scope of this drone. CyPhy also stated that in the future, the focus of this type of mini drone should be used in search and rescue operations. It can help rescue workers in the collapsed building or other situations to check the situation inside and prevent people from blindly entering. The necessary accident.
At present, CyPhy has not indicated when this drone was actually used, but it is believed that it will not be long before it will play an important role in disaster relief.
UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have ESD UPE SHEET,CONDUCTIVE UPE.
Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.
Advantages:
1. Average molecular weight about 5,000,000 to 9,000,000;
2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;
3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);
4.Low friction coefficient ,lubricity is equal to that of Teflon ;
5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;
6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;
7.Strong adhensive resistance which is only second to Teflon;
8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;
9.Low density than any other thermoplastic ;
10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;
11.Moderate mechanical strength,stiffness and creep-resistant property'
12.Outstanding machining property ,very low water absorption .
Deficiencies:
Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".
From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.
Applications:
Papermaking industry : suction box boards ,scrapper,molding plate ,beating ,gear .
Mining industry : charging barrel ,abrasive and adhensive -resistant back lining for warehouses.
Chemical industry : acid pump ,fliter plate , worm gear ,bearing .
Food industry :packing machinery parts ,bottle guide ,screw .wear plate ,slide away ,stud weld ,roller and other transmission parts.
Tenxile industry : buffer board
Food processing industry : chopping block ,refrigerating plant
Wharf:anti-collision board
Specification: the thickness of UHMW-PE Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width can exceed 1200mm, and the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 600mm* 1200mm, and the commonly used specification of 10-180mm is 1200*3080mm. UHMW-PE Plastic can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.
Color: Black and white, can also be made another color, and the color order is 500KG.
Modified varieties: UHMW-PE Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
Product certification: most environmental certification reports and safety reports forraw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
