What are the differences between industrial clean rooms and biological clean rooms?

Clean room, also known as clean room or clean room. It is the foundation of pollution control. Without clean room, pollution sensitive parts can not be mass produced. In FeD-STD-2, a dust-free room is defined as a room with air filtration, distribution, optimization, construction materials, and apparatus. In which specific rules of operation procedures are used to control airborne particulate concentrations so as to achieve appropriate particulate cleanliness levels. Dust-free room refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space range; And the indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise and vibration and lighting, static control in a certain range of needs, and given a specially designed room.

Industrial clean room

I. Research object

The research object of industrial clean room is dust, particle and other primary pollution. The continuous growth and reproduction of living particles such as microorganisms and bacteria in the biological clean room will induce secondary pollution (metabolites and feces).

Control methods and purification measures

Industrial clean room is mainly to take the filtering method. Coarse, medium and high filter, coarse, medium, high and ultra-high filter and chemical filter. Biological clean room is mainly to eliminate the growth conditions of microorganisms, control the breeding and propagation of microorganisms and cut off the transmission of microorganisms. Filtration and sterilization.

Third, the purpose of control

Industrial clean rooms control the concentration of harmful particles. Biological clean rooms control the production of microorganisms. Reproduction and transmission, while controlling metabolites.

Biological clean room

Four, the harm to the production process

As long as a dust in the key part of the industrial clean room can cause great harm to the product. Biological clean room is different, harmful microorganisms can only pose harm after reaching a certain concentration.

Five, clean room building materials requirements

All materials of industrial clean room (wall, top, ground, etc.) do not produce dust, dust, friction resistance. All materials in the biological clean room shall be resistant to water. Corrosion resistance and can not provide microbial breeding and reproduction conditions.

6. Control of entry of people and objects

People entering the industrial clean room should change shoes, change clothes and blow. Objects should be cleaned and wiped when entering. People and things should be separated, and clean and unclean should be separated. People entering the biological clean room should change shoes, change clothes, shower and sterilize. The object should be cleaned, wiped and sterilized when entering. Air entering to filter, sterilization, character shunt, cleaning shunt.

Seven, detection,

Dust particles can be used to detect instantaneous particle concentration and display prints. The instantaneous value cannot be measured by microorganism detection in biological clean room. The colony count can only be read after 48 hours of culture.
