1945, the us navy used dry ice as a spraying medium to remove all kinds of grease.
1963, Reginald Linde obtained a patent for "removing meat from bones" by spraying carbon dioxide particles.
1972, Edwin Reiss obtained a patent for "removing residual parts on objects by spraying high-speed dry ice particles".
65438-0977, Calvin Feng obtained the patent of "volatile particle medium sandblasting".
In the early 1980s, the United States solved the clean maintenance of satellite navigation system and nuclear power generation system in military field by using dry ice particle jet trajectory and low temperature cracking principle. At that time, the ice maker was rough in appearance and huge in size, weighing about 60 tons. Moreover, the manufacturing efficiency of dry ice particles is very low, the hardness is not high, and the specifications and sizes are single, which greatly restricts its utilization.
At the end of 1980s, due to the continuous development of processing precision and integrated circuit technology, the dry ice manufacturing machines and jet machines in the United States have been greatly improved, greatly reduced in size and reduced in weight to 2 tons. Moreover, the utilization rate of CO2 is increased by nearly 2 times by using micro-circulation cryogenic technology, and dry ice particles with different hardness and size are produced, which reduces the cost and makes the technology change from military to civil and industrial fields and develop rapidly. Dry ice cleaning technology is widely used in developed areas such as the United States, Europe and Japan. It plays an important role in tire, casting, plastics, rubber, baked goods, aviation, automobile interior production and other fields. , saving a lot of cleaning costs for enterprises and bringing great benefits to environmental protection. Dry ice cleaning is widely used in aircraft maintenance and aircraft paint removal by the US Air Force, and so is Boeing. Every factory of Goodyear Tire Company uses dry ice to clean tire molds; Volvo, GM, Ford, Toyota, Honda and other automobile companies all use dry ice to clean casting molds. Germany, Norway and Japan have applied dry ice cleaning to shipbuilding.
In the 1990s, this technology was only briefly introduced in some professional books and magazines such as cleaning and casting in China.
At the end of 1990s, dry ice cleaning equipment and foreign complete sets of equipment were introduced at the same time. Shanghai Automotive Nonferrous Foundry Factory, which used dry ice cleaning earlier, gained great benefits from dry ice cleaning, effectively ensured the quality of castings and improved production efficiency. In recent years, some foreign-funded enterprises and large state-owned enterprises have also introduced or used foreign dry ice cleaning equipment, such as East China Tektronix, Shanxi Yaxinke, Michelin Tire, Liaohe Oilfield, Dongfeng Motor and other enterprises. Professional cleaning companies, FAW Foundry, Kunshan Cooper, Xi 'an Hydropower, Yangzi Petrochemical and other enterprises have all applied domestic dry ice cleaning equipment to solve the problem of clean production.
The manufacturing industry in the world is gradually shifting to China. China has promulgated the Law on the Promotion of Cleaner Production and other laws to vigorously promote cleaner production, focusing on the development of processes, equipment and technologies with high resource utilization and low pollutant production, and replacing backward processes, equipment and technologies with high material consumption, energy consumption and pollutant production. Environmental pollution legislation will also continuously and strictly control industrial emissions, requiring enterprises to carry out "clean production". In May 2005, the National Development and Reform Commission issued the "Policy Outline of Water Saving Technology in China", which clearly pointed out that "developing equipment cleaning technology. Constantly promote dry ice cleaning, spray cleaning, online cleaning and other technologies. " All these provide a good opportunity for the application and promotion of dry ice cleaning technology in China, and dry ice cleaning technology will be more applied and developed.
