The Origin of Cleanrooms
The Development and Importance of Air Purification Technology
1. Time of Origin
Air purification technology first developed in the United States during World War II, primarily for military applications to meet wartime needs (the discovery of axonal fission in 1939 led to its deployment in Hiroshima, Japan in 1945). The core of air purification-the high-efficiency particulate air (HEPA) filter-was successfully developed at that time. my country successfully developed HEPA filters and laminar flow cleanrooms in the early 1960s, experiencing rapid development after 1975. Manufacturers and product varieties and quantities gradually became standardized, and materials, accessories, and equipment used in general cleanrooms are now domestically produced.
2. Application Areas
Military: Aircraft, warships, missiles, nuclear weapons
Industrial Sector: Optics, machinery, chemical industry, aerospace, semiconductors, electronics
Others: Medical, pharmaceutical, bioengineering, animal husbandry
In short, with the development of economy and science and technology, the application of air purification technology in various industries is increasing, occupying an important position. The level and application of air purification technology has become an important indicator of a country's and region's modern economy and technology.
