Spacecraft cabin seals seamless anti-radiation

Small cross-sectional size of the largest one seal but a few centimeters, but used in the "seven gods" but manned space systems play a big responsibility. Seals to ensure spacecraft cabin space suits and good air tightness, in order to protect astronauts normal pressure environment and safety.
Since 1999, successive "Shenzhou" spacecraft cabin dozen sets, thousand pieces the size of the seal are four homes forty-two aerospace development and production, product inspection pass rate last post was 100%. And the "seven gods" extravehicular clothing has a special purpose such seals rubber parts, on a total of nearly 50 kinds of specifications, thousands of products.
Spaceship spacecraft cabin cabin marker cable ties are a key component of the sealing structure plays a spaceship in outer space isolation, supporting the safety of astronauts independent living environment an important role in the United States "Challenger" is because a small transmitter gasket problems and failure. Since the complex environment of outer space, requiring high vacuum seals, -50 ℃ to 200 ℃ alternating high and low temperature, UV radiation, charged particle irradiation and the use of atomic oxygen and other special circumstances, no degradation, aging and cracking, and always maintain a reliable sealing performance.
Chinese astronauts wearing spacesuits made their extravehicular activities, is the "seven gods" flying the biggest bright spot. Aerospace four homes bear this much people and the world attention Spacesuit rubber products development and production. EVA suits rubber products in addition to seamless, with radiation, anti-UV, cold and hot temperatures and other functions, their safety, reliability and design life and other demanding. Which is the product of the rubber Cable tiefollowing the spacecraft manned spaceflight after another application fields.
