Talking about the development history of clean technology

Mar 20, 2021

China's clean technology started in the early 1960s. In 1964, a sodium flame test bench for high efficiency filters was built. In 1965, the Air Conditioning Research Institute of the Chinese Academy of Building Research developed GS series high efficiency air filters with blue asbestos fiber filter paper (for later use) and GB series high efficiency air filters with ultra-fine glass fiber filter paper. In 1973, China’s first dust particle counter model J-73 (measuring range 0.3~10μm) and monodisperse polystyrene latex standard particles (PSL) for calibration of particle counters were successfully developed. ED-STD-209A standard 100,000 to 100 clean workshop design and construction.


From the late 1970s to the late 1980s, it was the stage of maturity and development of China's clean technology.


In 1979, the Air Conditioning Institute of CABR organized the compilation and publication of "Technical Measures for Air Cleaning", which was China's first normative document on clean technology.


n June 1982, the Clean Technology Branch of the Chinese Institute of Electronics (CCCS) was established, and the professional magazine "Clean and Air Conditioning Technology" was published, which played a significant role in promoting the progress of clean room technology and international exchanges.


In 1984, the national standard GBJ73-84 "Code for Design of Clean Workshops" was issued, and now the latest version is GB 50073-2013 "Code for Design of Clean Workshops". Later, according to the needs of the industry, various clean technical specifications and standards of electronics, medical and health, food, and microbiological safety have been published.


After the 1990s, China's clean technology has gradually integrated with the international standards. From the theoretical research of clean technology to the research and production of clean products, and the detection and control of clean environment, my country has gradually reached the level of developed countries in the world.

In recent years, most areas of our country have been more and more severely affected by smog. The concept of home purification has begun to spread. Cleanliness has gradually penetrated into everyone’s thoughts and lives. Related new technologies and products continue to emerge, which will become a new industry in the clean industry Opportunities and development points.
