The product description

On October 19, 2019, members of the OBS laboratory team joined the "Ocean Geology No. 4" to arrange 6 independently developed "Panshi" in the northwest sub-basin of the South China Sea. Until May 15, 2020, all 6 "Panshi" signs The 7-month subsea seismic data acquisition experiment in the deep water area of ​​the northwestern basin of the South China Sea ended successfully, and the instrument recovery rate reached 100%. All were successfully recovered. After preliminary analysis on site, the data quality was good and the expected goal was achieved.

"Pan Kun" dived to the sea floor of 3800 to 4100 meters this time. In this exploration activity, the solid buoyancy material provided by the blue whale soaring is indispensable. So what are the advantages of buoyancy materials that blue whales take off?

1,  Low density (0.2~0.7g/cm³)

Its own density is much lower than that of water, providing as much buoyancy as possible per unit volume, thereby improving the working performance of the equipment

2,  Low water absorption rate (not more than 3%)

Provides stable buoyancy under large water pressure to ensure safe and reliable work.

3,  High mechanical strength (compressive strength 1~100MPa)

It has excellent pressure resistance and can withstand the full range of hydrostatic pressure in the marine environment. 

4,  Corrosion resistance, good weather resistance 

5,  Excellent machinability

Can use sawing, planing, turning, grinding and other processing methods, according to customer needs to process the size and shape, easy on-site assembly.

Not only that, the application of solid buoyancy materials is also very extensive, including buoys, floats, ROV/AUV underwater robots, underwater submersibles, buoys, submersible system and offshore oil exploration systems can be used to provide Stable buoyancy.
