Description
hardware flow control. It is an ideal choice in the field of industrial automation.
How important ultra-precision polishing process is in modern manufacturing industry, its application fields can directly illustrate the problem: integrated
circuit manufacturing, medical equipment, auto parts, digital accessories, precision molds, aerospace. “It is the soul of technology.” The United States and
Japan have firmly grasped the initiative in the global market, and their material composition and production process have always been a mystery. In other words
, purchasing and using their products does not mean that you can imitate or even copy their products.
Epoxy Resin 25″Epoxy resin has insufficient toughness, and domestic carbon fiber lacks strength” (Science and Technology Daily, June 27)
Carbon fiber can be lighter than metal aluminum, but its strength is higher than steel. It also has properties such as high temperature resistance,
corrosion resistance, fatigue resistance, and creep resistance. One of the key composite auxiliary materials is epoxy resin. However, all the epoxy resin used in the
high-end carbon fiber currently produced in China is imported. At present, my country is able to produce higher-end carbon fibers such as T800, but Japan”s Toray mastered this
technology in the 1990s. Compared with carbon fiber, my country”s high-end epoxy resin industry lags behind the international situation even more seriously.
High-strength stainless steel 26 “The rocket engine “rust disease” that cannot be removed” (Science and Technology Daily, June 28)
Steel used in rocket engines needs to have a variety of properties, among which high strength is an important indicator that must be met. However, the strength and rust-proof performance
of stainless steel are a contradiction that is difficult to have both. If the rocket engine material is severely rusted, it will have a great impact. Relying entirely on the material itself to achieve both
high strength and anti-rust properties is a worldwide problem. Nowadays, most of our country”s aerospace materials use foreign materials used in the 1960s and 1970s. Developed countries
will strictly control the impurity content during the production process. If the purity does not meet the standard, it will be re-sold. However, domestic manufacturers often lack this rigorous control. manner.
