In recent years, with the development of modern science and technology and the deepening of the new round of industrial revolution. Digital and intelligent technology has profoundly changed the production mode and industrial form of manufacturing industry, and the breakthrough of new materials, new energy and other technologies will lead to a new round of technological and industrial changes.
Especially in the process of production of high-tech products, to meet the miniature precision, product processing, high purity (high quality), high reliability requirements and other issues, put forward higher requirements on the level of clean production environment. On the other hand, with the development of modern biomedical requirements, the control of the number of bacteria and microbial contamination in a clean room is also rising, in order to ensure medical medicine, biological research, food production and other industries from microbial contamination or infection. Industrial clean technology and bio clean technology will be with the development of science and technology and industrial products change rapidly and rapid development, has become one of the most important technology indispensable in modern industrial production and scientific experiment activities.
At present, environmental clean technology has been widely used in all walks of life or other requirements to prevent particle pollution, microbial pollution control, because the gap between industries is larger, and the requirements are different, so the control environment the contents and indexes are not the same. Here is a summary of the requirements of the common industry clean technology.
1, pharmaceutical products, clean room requirements
Medicine is a special commodity which is used to prevent and cure diseases and to recover and adjust the function of organism. If some drugs in the manufacturing process by microorganisms, dust particles and other pollution or cross contamination, may produce unexpected diseases and hazards.
2, clean room requirements for medical applications and medical research
Industrial cleaning technology and industrial clean room are widely used in industrial environment control with integrated circuits. In medicine, biological clean room is used to control microbial contamination. In the biological clean room, these microbes are composed of bacteria and fungi, the size of the size of more than 0.2um, the size of the bacteria are generally more than 0.5um, and most of the other particles attached to the material. Biological pollution channels not only through the air, but also with the human body, with the operator's clothing related.
In the field of medical research, the biological laboratory, the sterile laboratory as well as the "special feeding animal" feeding room for Biochemistry and medical experiments also need to control microbial contamination.
3, precision machinery and fine chemicals production of clean room requirements
With the development of science and technology, many industrial products production and processing of production environment in the dust concentration put forward high requirements, which requires all kinds of related material supply quality has a certain air cleanliness level and control the production process of the production environment. For example, in the production of film, if the film is contaminated by dust, emulsion oxidation will occur, reduced activity, pH value and so on, thus affecting the photographic properties of the film.
4, semiconductor, integrated circuit production clean room requirements
Purification of semiconductor materials as an important basis for the development of semiconductor devices. Because the technological requirements of large-scale and ultra large scale integrated circuit, in order to obtain the silicon material with high purity, cleanliness as raw materials and intermediate medium of high purity and production environment a prominent problem affecting product quality.
The yield of the integrated circuit chip is related to the defect density of the chip, and the defect density is related to the number of particles in the air. Therefore, the rapid development of integrated circuits, not only has the high request for the control of particles in the air but also need to further control the size and number of particles; at the same time, also have the relevant requirements for chemical pollution control of ultra large scale integrated circuit production environment.
5, cosmetics, food production clean room requirements
Modern cosmetics contain protein, vitamins, amino acids, plant extracts, etc., these components are bacteria, fungi and other micro-organisms breeding, breeding provides favorable conditions. Therefore, microbial contamination is an important factor affecting the quality of cosmetics. The control object of the clean room used in the production process of cosmetics is mainly dust particle and microorganism, which is similar to the clean room used in the production of drugs. At present, the level of air cleanliness of clean room for cosmetic production can be carried out according to the GMP standard.
In the production process of food factory, strict management of facilities is to ensure the safety and health of food, to prevent the occurrence of the important pathogenic Escherichia coli, Salmonella causing food poisoning or drink into the mold. Since 1990s, WHO and some developed countries have introduced the HACCP (hazard analysis key control point) system, developed the use of health management production process of food production recognition system.
Clean room and electronic, pharmaceutical, biological engineering, medical and health, food, cosmetics and military industries are inseparable, to meet the production needs of the controlled environment, a direct impact on product quality. However, due to the cleanliness of the clean room requirements of various industries are inconsistent, so in the clean room design should comply with the relevant standards to ensure that the clean environment to meet the required standards.
In recent years, with the development of modern science and technology and the deepening of the new round of industrial revolution, developed countries have implemented the strategy of re industrialization. Digital and intelligent technology has profoundly changed the production mode and industrial form of manufacturing industry, and the breakthrough of new materials, new energy and other technologies will lead to a new round of technological and industrial changes.
