Amazing Secrets: Why not see F-20 rivets

                                        After an anti- aircraft J20 appear different from the past , the whole body almost see the rivets, some people said it was because the stealth coating covers the outside , titanium bicycle frame so you do not see the rivets , in fact, this is wrong. F22 is using rivets , close look carefully you can see it. Why not F22 rivets completely covered with a coating to see it? This is because the skin is F22 by a piece of riveting rivets up, rivets can not cover for easy maintenance , in case you can quickly remove the rivets skin pulls off a piece , and can determine with the naked eye whether the fuselage skin cracks.
    So J20 Why not see rivets it? In fact, this and related processing technology , due to the advances in technology, a large piece of titanium alloy ingots J20 using whole body casting , extrusion and then press through a dedicated , increased density , ( the two years prior to the successful development of the machine , once media have reported that this is the aircraft fuselage presses developed specifically for J20 ) , and finally the use of CNC machine tools hollowed out , which is a ** , high-precision CNC machine tools , Titanium Artificial Joint the entire titanium aluminum alloy castings ( diameter may up to 3 meters ) hollowed out into the shape of the aircraft fuselage , so the aircraft do not need to cover the skin, the skin of the fuselage frame and a titanium alloy ingots are then processed , so do not see J20 rivets.
    Such a process can greatly increase the strength of the aircraft , but also improve the accuracy of processing a lot , this is a revolutionary advancement process of the aircraft fuselage . Aircraft ever built up step by step , first build a titanium alloy frame , between the frame and bolted punch , then use a rivet on the skin . These processes entirely by hand , the precision is difficult to control , and if the bolt which does not clench or aging can lead to serious disintegration of the entire aircraft , light can also cause skin Titanium Golf Club Heads cracking, so planes have to be done to test the static -destructive testing whether the aircraft design strength . And because of the introduction of new processing technology J20 , the whole body is one, to achieve the best strength to do after high air maneuvers lead to the disintegration of the body will no longer appear .
    After processing J20 in the fuselage just put on the surface of the fuselage stealth patch, we note the following diagram , J20 stealth patch is pasted a block , a bit like a submarine acoustic rubber blocks. If you later off a piece of stealth patch just paste a new on OK, so the aircraft maintenance is very easy .
    J20 of the integral processing technology is currently the world's first application in aircraft , F35 will still rely on the rivet , not to mention the Russian T50 , 20 years ago, the process is completely , there is no fundamental and J20 comparable. So an advanced aircraft can not just look at the surface , J20 to strategic needs ( to carry large amounts of fuel to increase range and large anti-ship missiles ) and designed long body, such a body if the old conventional processing technology we rely the naked eye does not feel his body proportions , the body is too long , the body is weak at the middle of stress , Titanium Casting Golf Heads where the most easily broken, but after the introduction of new technology completely eliminates this drawback . So just come out when J20 foreign aircraft design experts feel incomprehensible , but once the solution to doubt its processing will become clear.

In recent years, with the development of the electronics industry, has become a well-known germanium semiconductor material excellent . titanium investment casting Scientists have recently discovered that it is not only the electronics industry "food " and singular role in human health , cancer, the cancer .
Germanium in the human body functions are manifold. First, because it has the dehydrogenation capacity , enabling the body to maintain adequate oxygen , thereby safeguarding human health. In humans, the decomposition is carried out by means of oxygen . Food decomposition process , need to consume oxygen , water and carbon dioxide while . Without sufficient oxygen , it is possible to make the body to cause disease. The human body can germanium hydrogen ions out of the body to reduce the demand for oxygen , which is conducive to health. Japanese scientists added dimethyl germanium oxide polymer in honey become popular health products.
The most attention is organic germanium ( Ge dicarboxyethyl trioxide ) anti-cancer effect. According to the study and practice has proved that organic germanium with the body's " waste" with the body and the blood vessel wall excess protein and cancer will be adsorbed , 20 to 30 hours later, with a "waste " of germanium, will automatically excreted from the body . Cancer patients the blood is hypercoagulable state , slowing blood flow velocity , cancer easily attached to the vessel wall , invasion and destruction of the vessel wall. Meanwhile, the blood viscosity, easy to form blood clots, wrapped up the cancer cells , the drug is difficult to work. Since organic germanium has a role in lowering blood viscosity , which can slow down the effect, have anti-cancer effects .
Pure germanium ( 99.999 %) of the function:
( 1 ) enhance immune function
( 2 ) regulation of blood pressure , blood lipids , blood glucose and other physiological functions.

Titanium and titanium alloy of high strength

The effect of the Titanium alloy valves in the pipeline is to prevent the backflow of fluid. Common use of more than a check valve in plumbing, exports more than installing the pump check valve, so that when the pump stops, the water pipeline will not turn the clock back; pump suction pipe head also has a check valve, so that it Sheung Shui can be maintained when the next start. Common spring-type check valve, lift and swing. Also used in the hydraulic check valve, the hydraulic system can maintain pressure. Titanium alloy sheet is usually installed in the export position of the pump. Titanium check valve, also known as check valves, determined according to the specific needs of the pipeline installation direction. If the installation location of the pipe is vertical, you can choose from spin type, pipeline. If the pipe is horizontal mounting position, you can choose the lift. Lift check valves open and close the fastest. Spin from the check valve of least resistance. Pipeline check valves are generally mounted on the clip-on approach in the majority, are not suitable for installation distance off place. titanium alloy sheets  widely used in various pump outlet pipe, extraction pipes, drains, and other media are not allowed back in the pipeline. Before the use of the titanium check valve is a pressure differential valve which automatically open and close the valve, it is the role of the medium flow in one direction only, and to prevent the reverse flow. According to their different structures, the check valve can be divided into lift (jump centripetal) and swing (roll plate) two. Lift check valve must be installed in horizontal pipelines, and make strict vertical axis of the valve in a horizontal plane, in order to ensure a flexible and reliable operation of the valve lift of. Swing check valve as long as the rotation pivot horizontally, can be installed in any horizontal, vertical or inclined pipeline.
