1June, 943, Biro and his brother George (chemist) applied to the European Patent Office for a new patent and produced the first commercial ballpoint pen-Biro ballpoint pen.
The British government bought the right to use this patented ballpoint pen so that the crew of the Royal Air Force could use it. In addition to being stronger than traditional pens, ballpoint pens can also be used in low-pressure and high-altitude areas (in high-altitude areas, the ink of traditional fountain pens will overflow).
Extended data
1948, the first domestic ballpoint pen in China was born in Shanghai Fenghua ballpoint pen factory. After the reform and opening up, driven by the huge export demand, pen factories have sprung up.
In 20 1 1 year, the relevant departments of our country started the project "R&D and industrialization of key materials and preparation technology in pen-making industry", and the state allocated nearly 60 million yuan to support relevant scientific research institutions and enterprises to carry out scientific and technological research on neutral ink manufacturing, stainless steel wire rod for nib and processing equipment.
Through unremitting efforts, the project passed the acceptance of the "Twelfth Five-Year" National Science and Technology Support Plan on 20 15, and achieved a series of technological breakthroughs. For a long time, the dilemma of "import dependence" that has plagued China's pen-making industry has gradually been reversed.
The production process of written products is the core secret of foreign enterprises. Wang Huimian and others must independently develop an unprecedented steelmaking process. Without any reference, we can only accumulate data, adjust parameters and design process methods.
After five years of countless failures, TISCO finally saw nib steel with uniform additives under the electron microscope, and the experiment was successful in September 2006. After more than ten large-scale steelmaking, the first batch of steel with good cutting performance was finally produced. This batch of stainless steel wires with a diameter of 2.3mm can proudly write down the sign of "Made in China".
