Industrial clean technology and bio-technology will clean along with the development of science and technology and industrial products with each passing day and rapid development, has become one of modern industrial production and scientific experiment activities indispensable technical signs.
Currently, clean technology has been widely used in various industries or other environmental controls required to prevent particle contamination, microbiological contamination, since the gap between the different large and requirements of various industries, and therefore control the content of the environment, indicators are not the same. Here's to the common requirements for clean technology industry were summarized.
1, the production of pharmaceutical clean room requirements
Drugs for the prevention and treatment of disease and recovery, adjust the body functions special commodity, its quality is directly related to people's health and safety. If some medicines by microorganisms, dust and other contamination or cross-contamination in the manufacturing process may produce unexpected illness and harm.
2, medical research and medical applications in clean room requirements
Integrated circuit as the representative of industrial environmental control in the use of industrial clean technology and industrial clean rooms; and in medicine, the use of bio-clean room for microbiological contamination control. In biological clean room, more of these organisms and fungi by bacteria composition, particle size in 0.2um or more common bacterial particle size in 0.5um or more, and most other substances attached to the particles. Biofouling channels not only through the air, but also the body and clothing, and operator related.
In the field of medical research, biological laboratories, sterile laboratories and for biochemical, medical experiments with "special breeding animals' feeding room are also very necessary to control microbial contamination.
3, precision machinery and fine chemical products clean room requirements
With the development of science and technology, production and processing of many industrial products, the production environment of the dust concentration in enormous demands, which requires production environment has a certain level of air cleanliness and control of the production process requires various related substances supply quality. For example, film production, film if contaminated dust, oxidation will occur emulsions, decreased activity, pH value changes, thus affecting the performance of the photosensitive film.
4, the semiconductor integrated circuit production clean room requirements
The semiconductor material is purified as an important basis for the development of semiconductor devices. Due to large-scale and ultra large scale integrated circuit process requirements, in order to obtain high-purity silicon material, the cleanliness of raw materials and intermediary high purity and production environments has become a prominent issue affecting product quality.
Yield and chip defects density integrated circuit chip, whereas the chip defect density and the number of particles in the air about. Thus, the rapid development of integrated circuits, not only in the air to control the particle size of the high demands, but also need to further control the number of particles; at the same time, the chemical pollution control VLSI production environment is also related requirements.
5, cosmetics, food production and clean room requirements
Most modern cosmetics contain protein, vitamins, amino acids, plant extracts, etc., which are divided into groups of bacteria, mold and other microbial growth, reproduction provided favorable conditions. Thus, microbial contamination is an important factor affecting the quality of the cosmetics. Cosmetics production control objects used during the clean room is mainly dust, microbes, drug production and use of clean room requirements are similar. At present, the cosmetics production of clean room air cleanliness level can refer drug GMP norms.
Food factory production process, strict management facilities is to ensure food safety and hygiene, prevent pathogenic E. coli, salmonella poisoning caused by the food or drink mixed with mold and other important means occur. Since the 1990s, WHO and a number of countries introducing HACCP (Hazard Analysis Critical Control Point) system, developed using health management of the production process of food production recognition system.
