In recent years, news about graphene has been receiving much attention, whether it is the EU's flagship research project on graphene as one of the first technology flagship projects, or the study of national graphene in the University of Manchester during President Xi Jinping's visit to the UK. The hospital, etc., every time it appears, it is plucking the heart of the masses: the progress of graphene is a small step, and the world will make a big step forward. Graphene has been officially launched since 2004, but it has only developed rapidly in 12 years. In 2010, two scientists, the University of Manchester, André Jem and Kestyanovo, were found to have won the annual Nobel Prize in Physics for their graphene. Since then, graphene-related research and industrialization have continued to heat up and culminate. Since 2011, global graphene patent applications have exploded. As of 2013, there have been more than 5,000 inventions related to the manufacture and application of graphene in the world, which is 50 times that of 2004. Europe, the United States, Japan, South Korea and many other countries and regions have carried out a series of related research, supported many projects, and made strategic arrangements for promoting industrial development. Figure 1 The red part is the country and region where graphene is mainly distributed. Figure 2 The world's countries invest more in graphene research. From 2012 to 2013, the commercial market of graphene technology is slow, almost zero, and there are few representative products. appear. Since 2013, the graphene market has ushered in a rapid development period; in 2015, the world's first graphene intelligent physiotherapy waistband developed by Enwang Technology has raised a huge wave in the industry. According to the Seri Industrial Research Institute, the global graphene market may reach US$195 million in 2018, and will accelerate its development in the future, exceeding US$1.3 billion in 2023 (as shown in Figure 3). Figure 3 Global graphene market size forecast (in millions of US dollars) Although China's graphene research started late, it has a rapid development and potential advantages. In recent years, the number of domestic patent applications and the number of applicants has grown very rapidly, and the technical topics involved are also more extensive. Jiangsu, Chongqing, Shenzhen, Heilongjiang and Chinese Academy of Sciences have collaborated and innovated in various forms, and established industrial technology alliances to promote the optimization of innovative resources and the process of innovation and industrialization. China ranks third in the overall ranking of global graphene industry development strength, the top two are the United States and Japan. In terms of industrialization of graphene, 2015 became the first year of the outbreak of China's graphene industry. On March 2, 2015, the world's first 30,000 graphene mobile phones were released in Chongqing. The mobile phone uses the newly developed graphene touch screen, battery and thermal film to open a new era of graphene industrial application. After years of scientific research, the pace of industrialization of graphene enterprises in China has been accelerating, and the preparation process has shown diversified development. A few enterprises have the ability to produce large-scale graphene products.
Agriculture Bearings
The earth has given us rich and varied
food, agriculture equipment can be sown and harvested by human, the bearings
are the key to ensure long-term reliable operation parts.
ZXZ Bearings developed inch and metric: Disc
Harrow Bearings, Square Bore Bearings, Hex Bore Bearings , Insert Ball Bearings,
Insert With House Bearings and Ag Special Bearings .
Because the dirt and dust exit every day, so
the bearings must be effectively sealed. We can provide the excellent sealing
bearings for different applications, which can resist the most extreme ambient
conditions. All of these two-part seals consist of zinc-plated extremal and
sheet-steel internal, and are stacked in the outer ring. This keeps the dirt
outside and the grease inside.
