Difference between industrial clean room and biological clean room
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, regulated operating procedures are used to control airborne particulate concentrations to achieve appropriate particulate cleanliness levels. Dust-free room refers to a specially designed room that eliminates particles, harmful air, bacteria and other pollutants in the air within a certain space range, and controls the indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise and vibration, lighting and static electricity within a certain demand range.
The differences between industrial clean rooms and biological clean rooms are shown in the table below
Comparison items: industrial clean room, biological clean room
Research Object (main)
Dust, particles only once pollution
The continuous growth and reproduction of living particles such as microorganisms and bacteria will induce secondary pollution (metabolites and feces)
Control methods purification measures
Mainly adopt filtering method. Coarse, medium, high three filters, coarse, medium, high, ultra-high four filters and chemical filters
Mainly to take: eradication of microbial growth conditions, control of microbial breeding, reproduction and cut off the transmission of microorganisms. Filtration and sterilization
Control objectives
Control the concentration of harmful particle size
Control the production, reproduction and spread of microorganisms, and control their metabolites
Harm to production process
Just one piece of dust in the key position can cause great harm to the product
Harmful microorganisms must reach a certain concentration before they become a hazard
Requirements for clean room building materials
All materials (wall, roof, floor, etc.) do not produce dust, dust, abrasion resistance
All materials shall be resistant to water and corrosion and shall not provide conditions for microbial breeding
Control of entry of persons and objects
People enter to change shoes, change clothes, blowing. Clean and wipe the material when entering. People and things to be separated, cleaning to be separated
People need to change shoes, change clothes, shower and sterilize; To wipe, clean and sterilize the material entering; Air feeding to filtration, sterilization, character shunt, cleaning shunt detection
