Hefengli Dry Ice has introduced to you the performance and functions of the Dry ice cleaning machine for so long, but forgot to introduce the history of the development of dry ice cleaning technology.

In 1930, "dry ice" made in the United States was used for experiments in the laboratory.

In 1945, the U.S. Navy used dry ice as a blasting medium to remove various greases.

In 1963, Reginald Lind received a patent for "removing flesh from the bones" by spraying carbon dioxide particles.

In 1972, Edwin Reiss was awarded a patent for the method of "removing residues from objects by jetting high-velocity dry ice particles".

In 1977, Calvin Feng received a patent for "Sandblasting with Volatile Particle Media".

      In the early 1980s, the United States used the principle of dry ice particle jet trajectory and low-temperature cracking to solve the cleaning and maintenance and special needs of satellite navigation systems and nuclear power generation system equipment in the military field. At that time, the ice machine was rough in appearance and bulky, weighing more than 60 tons. Moreover, the production efficiency of dry ice particles was very low, the hardness was not high, and the specifications were single, which greatly restricted its use.

       At the end of the 1980s, due to the continuous development of processing precision and integrated circuit technology, the United States made great improvements to the dry ice making machine and jetting machine, the volume was greatly reduced, and the weight was reduced to 2 tons, and the micro-circulation cryogenic technology was used to make CO2 use The efficiency has been increased by nearly 2 times, and dry ice particles of different hardness and sizes have been produced, which has reduced the cost, making this technology shift from the military to the civilian and industrial fields, and has developed rapidly.

      The application of dry ice blasting technology in developed regions such as the United States, Europe, and Japan is very common. It has played an important role in the production of tires, casting, plastics, rubber, baked goods, aviation, and automotive interior parts, saving a lot of cleaning costs for enterprises and bringing great benefits to environmental protection. Dry ice blasting is widely used by the U.S. Air Force for aircraft maintenance and aircraft paint removal, as is Boeing; every factory of Goodyear Tire Company uses dry ice to clean tire molds; Volvo, General Motors, Ford, Toyota, Honda and other automobile companies are all used Dry ice clean the casting mold. Germany, Norway and Japan have applied dry ice blasting to the shipbuilding industry.

     In the 1990s, some professional books and magazines on cleaning and casting in our country only briefly introduced this technology. In the late 1990s, dry ice blasting equipment was introduced in China while introducing foreign complete sets of equipment. Shanghai Automobile Nonferrous Foundry General Factory, which used dry ice blasting earlier, has obtained huge benefits from dry ice blasting, effectively ensuring the quality of castings and improving production efficiency. In recent years, some foreign-funded enterprises and large state-owned enterprises have successively introduced or used foreign dry ice cleaning equipment, such as East China Teksid, Shanxi Asimco, Michelin Tire, Liaohe Oilfield, Dongfeng Motor and other enterprises. Professional cleaning companies, FAW Foundry, Kunshan Cooper, Xi'an Hydro, Yangzi Petrochemical and other enterprises have applied domestic dry ice cleaning equipment, which has solved the difficulty of production cleaning.

      The world's manufacturing industry is gradually shifting to China. my country's "Clean Production Promotion Law" and other laws have been promulgated to vigorously promote clean production, focusing on the development of processes, equipment and technologies that have high resource utilization and low pollutant generation. Material consumption, energy consumption and pollution Outdated processes, equipment and technologies with large production volumes. Legislation on environmental pollution will also continue to impose stricter controls on industrial emissions, requiring companies to carry out "clean production". The "China Water Saving Technology Policy Outline" issued by the National Development and Reform Commission in May 2005 clearly pointed out that "develop equipment cleaning technology. Promote dry ice cleaning, spray cleaning, non-stop online cleaning and other technologies." These have provided a good opportunity for the application and promotion of dry ice blasting technology in my country, and dry ice blasting technology will be more applied and developed.
