Industrial clean technology and biological clean technology will surely develop rapidly with the development of science and technology and industrial products, and become one of the important technical signs indispensable for modern industrial production and scientific experimental activities.

At present, clean technology has been widely used in various industries or other environmental control that requires prevention of particle pollution and microbial pollution. Due to the large gaps between different industries and different requirements, the content and indicators of controlling the environment are different. The following is a summary of the common industry clean technology requirements.

1. Clean room requirements for the production of pharmaceutical products

Medicines are special commodities used to prevent and treat diseases and restore and adjust body functions. Its quality is directly related to human health and safety. If some medicines are contaminated or cross-contaminated by microorganisms, dust particles, etc. during the manufacturing process, unexpected diseases and hazards may occur.

2. Clean room requirements in medical applications and medical research

In industrial environment control represented by integrated circuits, industrial clean technology and industrial clean rooms are mostly used; in medicine, biological clean rooms are mostly used for microbial pollution control. In the biological clean room, these microorganisms are mostly composed of bacteria and fungi, and the particle size is more than 0.2um. The common bacteria have a particle size of more than 0.5um, and most of them are attached to the particles of other substances. Biological pollution channels not only pass through the air, but also relate to the human body and the clothing of the operator.

In the field of medical research, biological laboratories, aseptic laboratories, and "special breeding animals" breeding rooms for biochemical and medical experiments are also in great need of controlling microbial contamination.

3. Clean room requirements for the production of precision machinery and fine chemical products

With the development of science and technology, the production and processing of many industrial products place extremely high requirements on the dust concentration in the production environment. This requires a certain level of air cleanliness in the production environment and various related substances required to control the production process. Supply quality. For example, in film production, if the film is contaminated by dust, emulsion oxidation, weakening of activity, change in pH value, etc. will occur, which will affect the photosensitivity of the film.

4. Clean room requirements for semiconductor and integrated circuit production

Purification of semiconductor materials is an important basis for the development of semiconductor devices. Due to the process requirements of large-scale and ultra-large-scale integrated circuits, in order to obtain high-purity silicon materials, the high purity of raw materials and intermediate media and the cleanliness of the production environment have become a prominent problem affecting product quality.

The yield of integrated circuit chips is related to the defect density of chips, and the defect density of chips is related to the number of particles in the air. Therefore, the rapid development of integrated circuits not only has extremely high requirements for the size of control particles in the air, but also requires further control of the number of particles; at the same time, there are related requirements for the control of chemical pollution in the production environment of ultra-large scale integrated circuits.

5. Clean room requirements for cosmetics and food production

Most modern cosmetics contain proteins, vitamins, amino acids, plant extracts, etc. These components provide favorable conditions for the growth and reproduction of microorganisms such as bacteria and mold. Therefore, microbial contamination is an important factor affecting the quality of cosmetics. The control objects of the clean room used in the production of cosmetics are mainly dust particles and microorganisms, which are similar to the requirements of clean rooms for pharmaceutical production. At present, the air cleanliness level of clean rooms for cosmetics production can be performed with reference to the GMP specifications of pharmaceuticals.

In the production process of food factories, the strict management of facilities is an important means to ensure the safety and health of food and prevent food poisoning caused by pathogenic coliforms and salmonella or mold mixed in beverages. From the 1990s to the present, the WHO and some developed countries introduced the HACCP (Key Control Point for Hazard Analysis) system and formulated a food production recognition system that uses hygienic management of the production process.
