Recently, the international standard proposal for "General Requirements for CNC System for Industrial Automation Systems and Integrated Machine Tools" proposed by China has been approved by the International Organization for Standardization Automation System and Integration Technology Committee Physical Equipment Control Branch (ISO/TC184/SC1). It is ISO/ The first project proposed by China in TC184/SC1 and successfully established.
Under the joint efforts of the national science and technology plan support and the machine tool industry, such as the "high-end CNC machine tools and basic manufacturing equipment" technology major projects, China's CNC system has been greatly improved in terms of functions and performance, effectively supporting the innovation and development of the CNC system industry. The successful establishment of this international standard indicates that China's leading and discourse power in the work of international standard rules will be further enhanced.
Sulfate is a compound composed of sulfate ion (SO42-) and other metal ions. It is an electrolyte, and most of it is soluble in water. Sulphate minerals are salts formed by the combination of metal elements (including ammonium) and sulfate. Because sulfur is a valency element, it can produce different minerals in different valence states in nature. When it combines the highest valence S6 + with four O 2 - to form SO42 -, and then with metal cations, it forms sulfate. In sulphate minerals, more than 20 metal cations are combined with sulfate. That is, sulfate containing sulfate is sulfate.
