Recently, the international situation is like a tense and exciting blockbuster, and the four conflicts in one day are like a superposition of plots, which makes people wonder what kind of drama the director is arranging. From the flames of the Middle East to the drums of war in Asia, we can't help but ask: Is the world really a little turbulent?
Yes, on this day, the Palestinian-Israeli conflict burned like a fireball over the wilderness of the Middle East, and the United States dropped missiles on Syria, as if it did not want this fire to be extinguished. And in a corner of Europe, the smoke of gunpowder between Russia and Ukraine has not dissipated, and the line of fire is tight. Asia is also not calm, and the confrontation between the Kokang Allied Army and the ** Army in northern Myanmar has once again verified the heat of this region.
When we look to the Korean Peninsula and Kosovo, the unease is like a string being tightened, and everyone is worried about whether this string will suddenly break. The United States shouted war with great fanfare, and Japan followed suit, as if someone was secretly stirring up a waterhole.
U.S. imperialism seems to have played a big game on the international chessboard, and the chess pieces in this game are the fate of the country and the people. The conflict between Russia and Ukraine has turned over two calendars, and Ukraine, supported by the 30 NATO countries, is still in a quagmire. Behind this, Ukraine is nothing more than a pawn in the game of great powers, and the contest behind it is between NATO and Russia.
Russia, this fighting nation, even in the midst of financial blockade and ** difficulties, is still tenacious, straightens its back, and fights with the military shadows of thirty countries. Ukraine's role is far from being as simple as it seems.
The support of NATO countries is certainly warm, but none of them really jumped to the front line to confront Russia, and there is still a layer of paper between this support and the actual battle.
In the current situation, it is better to say that these countries are involved in the war than to watch the war. The United States may find itself in its own backyard if it continues to push the conflict**. So, if you really want to talk about World War III, there is a possibility in theory, but in fact, it is a card that most people are not willing to pick up.
In the era of high technology, the processing technology of special metals is more and more jaw-dropping, the toughness of steel, and the thickness is not directly related, cutting-edge technology has allowed the military industry to enter the era of hacker competition, special steel can be as thin as paper, or even only 0015 mm!Even the steel material that can be torn off by hand can be used as a life-saving charm for airplanes?
Hard as steel is people's intuitive perception of steel, high-tech means of special steel, with the blessing of special steel, can be torn by hand, but can save the life of the aircraft, and even an important raw material for the aerospace of the great country, known as the special metal of hand-torn steel, is the envy of all countries of the new black technology!
Difficult production processes.
As the name suggests, the thickness of hand-torn steel is very light and thin, less than a millimeter thick, and it can also be called steel
China's Shanxi Taigang Group has successfully produced stainless steel foil, referred to as hand-torn steel. This kind of steel shocked the world once it came out, and the thickness is only a quarter of that of A4 paper, 0015 mm of steel, which can be torn with bare hands. This special stainless steel can be folded many times without breaking, and its special volume characteristics can be widely used in many fields.
First of all, a brief understanding of the research and development process of hand-torn steel.
In the 20th century, China still needs to import from the West, and years of research and development can only reach 01 mm and 05 mm of steel, seemingly a small gap in numbers, but it is a gap in the field of scientific research.
Shanxi Taigang Group began to set up a hand-torn steel project in 2016, if understood from the research and development theory, the processing process of hand-torn steel only needs to continuously press the heavy steel plate to create an ultra-thin steel foil like paper. It can also be understood as the same state as plain tin foil, but the real thickness of hand-torn steel is only a quarter of that of paper.
These processes that can be easily introduced in theory are built with precision instruments and equipment, powerful and stable processing machines, and advanced and precise production processes, each step of which is a world-class problem and a very high threshold.
The selection of stainless steel raw materials has very strict standards, not all steel can meet the requirements of processing hand-torn steel, cold-rolled steel selection has strict parameter standards, the grain size range of raw materials, the surface smoothness index of steel, have strict requirements, there can be no small scratches, and the production thickness is 0For stainless steel materials within 025 mm, the grain size parameters should reach 7 to 9 grades, and if the raw materials do not meet the standards and standards, they will not produce high-quality hand-torn steel that meets the ductility and plasticity.
In 2018, the thickness of China's hand-torn steel R&D was 002 mm, a lot of progress has been made. After that, we will continue to make breakthroughs, and the scientific research team has gone through more than 1,000 days and more than 7,800 experiments, and finally set a world record of 0015 mm!At this point, China's hand-torn steel materials no longer need to be imported from the West, and the West can no longer monopolize it. This means that China's high-tech has the absolute initiative, and research and development in special fields can be arranged independently.
