The task of seafaring 3000-meter underwater robots undertaken by the Yantai Salvage Bureau of the Ministry of Transport concluded successfully on the 9th, indicating that China has already reached the 3,000-meter deepwater salvage capability. According to the Yantai Salvage Bureau of the Ministry of Transport introduced at 18:20 on the 9th, with the council "Germany n According to reports, the sea trial salvage system in our country without any mature experience can learn from. In the face of the huge challenge, Yantai Salvage Bureau organized many technical personnel and experts inside and outside the bureau to carry out discussions and reviews, and eventually formed a sea trial program that was in line with the characteristics of its own equipment and was scientifically feasible. In addition, the sea test at a depth of 3000 meters, the traditional anchoring method can not be completed accurate positioning, Yantai Salvage for this reason has selected two dynamic positioning system of 12000KW big horsepower tug "German n At the beginning of March this year, preparations for sea trial officially started. After a month of efforts, on-site technical personnel successively completed land testing, equipment mobilization, shipboard assembly, and system interworking. April 5, "De n On the 8th, the underwater robot conducted the third water test. After an hour and a half dive, when the water depth to 2735 meters, the underwater robot successfully reached the sea floor. Under the proposed plan, the underwater robot flew the umbilical cable management system for a 600-meter underwater flight. At the same time, technicians manipulate high-precision manipulators and put the signs labeled "Yantai Salvage Bureau of the Ministry of Transport" into the bottom of the South China Sea. Subsequently, the technicians tested all the main sensors, auxiliary equipment, mechanical hydraulic system, communication transmission and automatic control system of the underwater robot. All the performance and parameters were normal. At 18:30 on the 8th, the underwater robot completed all the test items and began to return to the surface of the water and smoothly discharged water at 20:00. According to Yantai Salvage Bureau technical staff, then the next underwater robot equipment will be officially delivered to use, Yantai Salvage Service national maritime power strategy and deepwater marine engineering development capability has reached a new level.
Aluminum adhesive tape is widely used in different industry.Aluminum foil has a clean, sanitary and shiny appearance. It can be integrated with many other packaging materials. Moreover, the printing effect of aluminum foil surface is better than other materials. In addition, aluminum foil has the following characteristics: (1) the surface of aluminum foil is extremely clean and hygienic, and no bacteria or microorganism can grow on the surface. (2) Aluminum foil is a non-toxic packaging material, it can directly contact with food without any harm to human health. (3) Aluminum foil is a kind of tasteless and odorless packaging material, which will not make the packaged food have any peculiar smell. (4) If the aluminum foil itself is not volatile, it and the packaged food will never dry or shrink. (5) No matter in high temperature or low temperature, aluminum foil will not have grease penetration phenomenon. (6) Aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine. (7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. It can also be made into containers of various shapes. (8) Aluminum foil has high hardness and tensile strength, but its tear strength is small, so it is easy to tear apart
