Trump is Building Economic and War Machines

"If you want peace, you have to prepare for war." On March 1, Donald Trump announced that his government would impose a 25% tariff on all steel imports and a 10% tariff on aluminium. Trump initially said tariffs would apply to all steel and aluminium exporters, but a week later, under pressure from Republican free traders, Mexico, Canada and Australia were temporarily excluded, while negotiations on the North American Free Trade Agreement continued.

The news led to an immediate drop in the stock market and sparked criticism from U.S. trading partners who said they would impose tungsten carbide sheet retaliatory tariffs on U.S. exports and crack down on trade restrictions imposed by the World Trade Organization. Although China is not a major supplier of steel to the United States, it is the world's leading producer and exporter of steel, producing nearly half of the world's steel. In other words, Trump is not foolish. He is dealing with China in the form of "knocking on tigers" and "beating cattle across mountains", because China often defies American trade rules by exporting steel and aluminium to third countries and then entering the United States.

Chinese steelmakers, which produce half of the world's steel, have long been the target of U.S. import tariffs, with 25% clearly targeting China. At present, there are 169 anti-dumping and countervailing duty orders, 29 of which are directed against China, of course, and more.

In early March, Robert Lethizer, the U.S. trade representative, submitted a tariff proposal to the White House aimed at China, demanding tariffs on $30 billion of goods imported from China. Trump, however, is not enough. He has made a big demand to double the size of the plan, which means it could reach $60 billion or even $100 billion.

The U.S. sanctions covers more than 100 Chinese products, including electronics, telecommunications equipment, furniture, toys and so on. The technology and telecommunications industries will be the focus of attention. Trump will soon announce the tax plan. Trump has threatened that he is considering imposing a huge "fine" on China in the area of intellectual property protection. "We're talking about figures you never even thought of." On March 7, he tweeted that China had been asked to draw up a plan to reduce a large trade deficit of $100 billion this year...

Americans have pointed out that the impact of tariffs on the U.S. economy and its trading partners is currently a controversial topic, but in order to study why Trump did so, it is necessary to go beyond the economic sphere. In doing so, Americans have found that Trump's protection of steel and aluminium and the recent call for domestic production of 35 strategic metals, such as rare earth and tungsten, are two rivals to build the U.S. military to deal with the growing threats in the world: Russia and China.

Although the United States was the first to promote the global steel industry, it is now the largest importer of steel, importing almost four times as much as its exports.

So the real reason why the United States imposed steel tariffs is China. Like Reagan before him, Trump believed in peace through strength. Although Reagan's evil empire was Russia, Trump's goal was China.

So on these two days, Trump took the initiative to sign the Taiwan Exchange Act. If Trump's steel and aluminium tariffs are an economic response to China's threat, Trump also wants to spread the economic war to the military. So Americans have been making trouble between Diaoyu Island, Taiwan and the Nansha Islands.

Unfortunately, globalization has completely reversed the tide of economic history, so now the United States needs to rely on most of its steel, tungsten, manganese, vanadium, chromium, lithium and other materials outside its borders to complete production, so politicians are always afraid of the country's current vulnerability.

So the final conclusion is that Trump actually wants to support the U.S. Army by rebuilding the U.S. steel industry and allowing more predictions of U.S. war power. What materials will the country need to achieve self-reliance? In fact, the answer has been revealed recently.

The U.S. Department of Internal Affairs recently announced that it will expand domestic production of 35 key minerals, including uranium, tungsten, cobalt, lithium, titanium and rare earths, in order to reduce dependence on foreign imports, especially those produced by China and Russia.

Why is there always such a Zgcc Cemented Carbide sinister and intentional country in the world that jeopardizes world peace? At this time, we should be more cautious in dealing with the threats posed by the United States, more calm and calm, and strive to make our motherland stronger. (China Tungsten Online: Weiping)

Lead Tungstate Crystals from Dongsheng Yan for Large Hadron Collider

Dongsheng Yan led his team to provide more than 5,000 new lead tungstate crystals for the Large Hadron Collider and won the CMS Crystal Award of the European Nuclear Center. He struggled for science and put a "coat" on the missile.

From the "scientific saving of the country" in his youth, to the rejuvenation of the country through the years of science and education, Dongsheng Yan integrated his life into the development of new generations of new materials in New China, and played an important role in the development of the national economy and the construction of major national projects. He is the founder of China's inorganic materials science, as well as an academician of the Chinese Academy of Sciences and Engineering.

Lead tungstate crystal (PbWO4) owns a melting point 1123 ° C, density 8.28g / cm3. It is an inorganic scintillation crystal with excellent comprehensive performance. Tungsten Carbide Round Rod PbWO4 owns properties of short radiation length (0.87cm), Moliere radius (2.12cm), fast flicker decay time (<50ns), and strong resistance to radiation damage, making it be used in high-energy physics research.

Taking country’s needs is the portrayal of Dongsheng Yan's scientific life. In 1918, he was born in Shanghai. In 1946, Mr. Yan went to the United States to study. During his studies at the University of Illinois, he received Ph.D. in ceramics with full A scores. After hearing the news of the founding of New China, he immediately gave up the generous treatment in US, and returned to his motherland resolutely.

At the beginning of returning China, he presided over the formulation of China's first refractory production, inspection, and testing standards, Cemented Tungsten Carbide and promoted the development of China's steel industry. In the 1970s, he was urgently ordered to lead more than 50 secret teams to conduct more than 300 types of sample tests in the extremely simple factory. The developed high-temperature ablation composite material successfully solved in New China. He was known as "the person who puts on coat on missile."

Mr. Yan led Shanghai Ceramic Research Institute to accumulate in the field of scintillation crystals. He immediately organized a team to tackle the problem and eventually won a supply contract for 12,000 BGO crystals. In 1985, the National Science Foundation of the US evaluated the BGO products of various countries, and Mr. Yan and his team attained this only chance. Therefore, when the CERN decided to build the Large Hadron Collider to find the Higgs boson, which required tens of thousands of new lead tungstate crystals to make the core components, it was natural to think of Mr. Yan.

At the end of 2003, the conditions were "harsh", as all the crystals had to be produced in four years and more, Mr. Yan did not "bargain" it. At the age of 85, he not only blurted out the test data of a series of PWO crystals but also personally went to the raw material production workshop in Kunshan city, Jiangsu province to check the crystal quality. In March 2008, Shanghai Silicate Institute successfully delivered about 5,000 high-quality large-size PWO crystals without any delaying. In that year, Mr. Yan was 90 years old.

Even at the age of 90, he was still at the forefront and planning his goals and plans for the future. As a project leader, Mr. Yan led his team to provide more than 5,000 new lead tungstate crystals for the Large Hadron Collider (LHC), and won the CMS Crystal Award from the European Organization for Nuclear Research (CERN). Dongsheng Yan has been fighting for our national science career through his life. This kind of patriotic feeling is the role model of younger generation to learn.

Over 1 Million Miles! Penn State Develops High

A Li-ion battery that is safe, has high power and can last for 1 million miles has been developed by a team in the Pennsylvania State University (Penn State) Battery and Energy Storage Technology (BEST) Center in the United States, according to foreign media report.

Generally, electric vehicle batteries require a trade-off between safety and energy density. If the Li-ion battery has high energy and high-power density, which is required for uphill driving or merging on the freeway, then there is a chance the battery can catch fire or explode under inappropriate conditions. But materials ground tungsten carbide rods that have low energy or power density, and therefore high safety, tend to have poor performance. There is no way to find materials that can meet both safety and energy density requirements. For this reason, battery engineers opt for battery performance over safety.

Chaoyang Wang, a professor at the mechanical, chemical and materials science and engineering of Penn State, and William E. Diefenderfer Chair said: "In this work we decided we were going to take a totally different approach. We divided our strategy into two steps. First we wanted to build a highly stable battery with highly stable materials."

The second step is to introduce instant heating. About 4 years ago, Professor Wang developed a self-heating battery to overcome the problem of poor battery performance tungsten carbide burrs blank in cold weather. This type of battery can be heated in a matter of seconds with an electric current, but it can take several hours with an external heater. By heating the battery from room temperature to about 140 degrees Fahrenheit (60 degrees Celsius), the battery gets an instant boost in reactivity because the law of kinetics is that reactivity increases exponentially with temperature. Professor Wang said: "With these two steps I can get high safety when the battery is not being used and high power when it is."

The self-heating battery, called the All Climate battery, has been adopted by many car companies such as BMW and is powering a fleet of 10,000 cars, which will be used to ferry people between venues at the next Winter Olympics in Beijing, China.

BEST Center tested the safety of the Li-ion battery using nail penetration equipment, caused a short circuit, and then monitored the battery temperature and voltage. The difference in temperature for the passivated cell was 212 degrees Fahrenheit (100 degrees Celsius), while the standard battery has a temperature difference of 1832 degrees Fahrenheit (1000 degrees Celsius), which is an enormous improvement.

Because the battery is made of stable materials, it has a long cycle life. Even at 140 degrees Fahrenheit (60 degrees Celsius), the number of cycles can exceed 4,000, which means that the life span can exceed 1 million miles.

The Penn State research team's next project is to develop a solid-state battery, which tungsten carbide burrs will also likely require heating. And Tesla has previously announced a Li-Ion battery with a life of more than 1 million miles. It seems that the wider popularity of electric vehicles is just around the corner.
