Polyurethane insulation power station construction Antarctic Tarzan

February 8 , China's Antarctic station was built and officially opened Taishan station . This is the second of the Great Wall Station and Zhongshan Station and Kunlun Station in Antarctica built our fourth research station , is the second inland Antarctic stations .

In the future, stands between the Zhongshan Station and Kunlun Station Taishan station will not only be the link between the two major stations , based on the scientific investigation of Taishan station in the Antarctic inland Grove Mountains region , will also be further strengthened , is in the region to collect meteorites , geology , glaciology and other scientific studies provide strong protection to help Chinese scientists unravel the mystery unsolved more polar and the universe .

Yangcheng Evening News reporter interviewed twice polar science researchers perform scientific expedition to the Antarctic Kunlun Station mission Cuixiang Bin , and engineers involved in the design Taishan station SUN Xu- Dong , decryption and China Taishan station in the Antarctic expedition staff struggled story.Sellotape

To combat climate polar special , high-tech Tarzan station systemic coagulation is gathered wisdom of Steel Construction 's top "technical control ."

Taishan station construction difficulty is much higher than the Zhongshan station , two stops from the temperature in which a single location can be seen. According to reports, the minimum temperature in summer Taishan station at -30 ℃, winter minimum temperature of about -60 ℃; while the minimum temperature in summer is the Great Wall Station -2.7 ℃, the lowest temperature even in winter , there are about -26.6 ℃. This makes it necessary to use special materials Taishan station construction , general building materials can not be used in the Antarctic inland . Ordinary plastic wires twisted together Taishan station will be frozen strip twist , a discount on the break ; ordinary concrete liable vapor infiltration volume expansion after freezing , bursting ; ordinary steel will soon appear here above contraction and cold embrittlement phenomena ; ordinary color-coated steel facades, in the Antarctic under the strong ultraviolet raging , will soon fade , chalking, a few years they all come off.

SUN Xu- Dong said, in order to withstand the test of Antarctic inland climate , Taishan station construction uses a lot of the best material. Steel in general, low temperature resistance, low temperature steel can withstand -40 ℃ and the lowest tolerable steel Titan station -70 ℃ to -100 ℃. Exterior wall coating , the coated with a fluorocarbon layer on the color-coated Taishan station can effectively resist ultraviolet radiation , known as the Antarctic building best " sunscreen ."Washi tape
 
Building insulation is the most important natural Taishan station construction . As the steel frame structure, and a large thermal conductivity of steel , for insulation , the designers have adopted a " cold bridge blocking technology ." Entire wall using the outermost layer of composite sandwich panels with insulation effect , it is a composite of fluorocarbon coating color steel and polyurethane insulation made ​​; intermediate bridge is used to block the cold wooden keel ; Beyond that steel skeleton ; interior walls are using rock wool sandwich panel : This material is not only heat , but also fire . Plus also means his best insulation windows, after the completion of Taishan station , under normal circumstances, the indoor temperature can reach 20 ℃, heating systems heat water can also be heated for players bath.Masking tape

Building such a harsh environment , with only 45 days on the built, because behind this there are " built like a car , like a house built " advanced technology. According to reports, Taishan station all building materials are in the domestic processing is completed, and after the pre- assembled and linkage testing, packaging and re- assembled shipped to the South Pole . To ensure that all the material in the Antarctic but not too much time to install , and can resist cold shrink under arctic , Sun Xu Dong and his partners after a fine calculation and coding , they even bore the nut assembly materials processed into oval , set aside space for thermal expansion and contraction .

Cuixiang Bin introduction, Taishan Station and Zhongshan Station in the middle of the ice near the Kunlun station at Dome A , but also from the Grove Mountains meteorite gathered close , can support our expedition to the Dome A region and the Grove Mountains on-site visits include major scientific direction geophysical surveys, deep ice core drilling , astronomy, science , etc., and meteorites .Wholesale masking tape
