The Development Of 3D Printing In China

Compared with the development level of foreign 3D printing technology, there is still a certain gap in our country, but don’t be discouraged, we also have our strengths and advantages in this industry. The research on china 3D printing technology started as early as the early 1990s. System of Chinese Academy of Sciences. At present, these universities are still the research centers of 3D printing technology in my country. Among them, Huazhong University of Science and Technology has the advantage of laser powder unsintering technology, Tsinghua University focuses on plastic accumulation technology and biomedical fields, Beihang University and Northwestern Polytechnical University mainly focus on In the field of metal Jinan 3D printers, Xi’an Jiaotong University mainly focuses on the field of photocuring in the whole field of 3D printing, and the development at home and abroad is also similar. In terms of equipment production, the functions of 3D printer equipment Read more

Advantages Of 3D Printing Technology In China

As the world’s factory, China naturally has advantages that other countries do not have, such as domestic 3D metal printing technology, so how good is China 3D printing Service? Its importance is not lost to the lithography machine. The United States has requested three times but was rejected? It turns out that China’s 3D metal printing technology leads the world, and its importance is not lost to the lithography machine. No wonder foreign countries can’t buy it with a lot of money. It is useful to circle it. 3D metal printing is a basic discipline used in physics, engineering and technical science , Scientific instruments in the field of mechanical engineering. In the field of mechanical processing, China started relatively late. In the industry, there is a term called standardization, that is, the components of industrial products are produced by the same process, which requires the use of machine tool Read more

3D Printing Service And Device In China

One weekend morning, a small 3D printing technology demonstration was being held in a cafe where entrepreneurs gathered in Haidian District, Beijing. The organizer is Tiertime Technology Co., Ltd., the largest portable 3D printer manufacturer and 3d printing China. This time they brought 8 desktop 3D printers with a height of only 13 cm. This event attracted many technology enthusiasts and technology enthusiasts. Many people brought their own 3D works, hoping to “print” these works with 3D printers. The printing process is very simple. The experiencer only needs to connect the printer to his own laptop through the USB interface, download the drawing software from the official website of Tyre, and import the 3D graphics file on the drawing platform; then start the printer, and the “ink” – ABS will be printed. After the plastic coil is installed on the printer, the computer will automatically import the 3D data into Read more

Comments Off on The new standard changes the ecology of the electroplating industry

As one of the four basic manufacturing processes, electroplating is widely used in various industries, such as high-end electronics, aviation, aerospace, energy, nuclear industry, low-end daily hardware, auto parts, stationery products, etc. Replaced service industries. According to incomplete statistics, in 2009, the number of electroplating enterprises (enterprises above designated size) in my country totaled 15,000, with more than 5,000 production lines and a production capacity of 250 to 300 million square meters of electroplating area. In recent years, with the remediation of heavily polluting enterprises by local governments, the number of electroplating enterprises has been on a decreasing trend. In 2008, the Ministry of Environmental Protection promulgated the “Emission Standards for Electroplating Pollutants” (GB21900-2008). The promulgation of the standards provides a basis for the management of key industries and key pollution sources. What problems does the new emission standard encounter? Need to find a balance between compliance with investment and Read more

Comments Off on Electroplating wastewater treatment process and principle of heavy metal removal

In terms of the total amount of electroplating wastewater, such as papermaking, printing and dyeing, chemicals, pesticides, etc., the amount of water is small, and the pollution surface is narrow. However, due to the wide distribution of electroplating plants, there are many types of highly toxic substances in the wastewater, which is very harmful. Untreated electroplating wastewater discharges into rivers and ponds and seeps into the ground, which will not only harm the environment, but also pollute drinking water and industrial water. Electroplating wastewater contains heavy metal ions such as chromium, zinc, copper, cadmium, lead, and nickel, as well as highly toxic impurities such as acid and alkali cyanide. Some are also highly toxic substances that cause cancer and distortion. Therefore, they must be dealt with carefully to avoid harm to people. (1) Typical process flow (2) Principle of heavy metal removal Generally, heavy metal ion removers can be used Read more
