Clean Room Construction And Acceptance Inspection
- View 11
Clean room refers to the particulates, 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 electricity control within a certain demand range, and to give a specially designed room. That is, no matter how the external air conditions change,clean room construction the indoor can maintain the original set requirements of cleanliness, temperature and humidity and pressure performance characteristics.
A clean room is a controlled environment with low levels of pollution from sources such as dust, airborne microorganisms, suspended particles, and chemical volatile gases Cleanrooms have a controlled pollution level, which can be determined by the number of particles per cubic meter of space, or by the maximum particle size.
electronics assembly cleanrooms: for the control of inanimate particles. It mainly controls the pollution of air dust particles to work objects, and generally maintains positive pressure inside. It is suitable for precision machinery industry, electronic industry (semiconductor, integrated circuit, etc.) aerospace industry, high purity chemical industry, atomic energy industry, optical magnetic products industry (CD, film, tape production)LCD(liquid crystal glass), computer hard disk, computer magnetic head production and other industries.
pharmaceutical & biotechnology cleanrooms: to control the pollution of living particles (bacteria) and inanimate particles (dust) to work objects. It can also be divided into:
A. General biological clean room, mainly to control the contamination of microbial (bacterial) objects. At the same time, the internal material should be able to withstand the erosion of various sterilizers, and the internal pressure is generally maintained. In essence, its internal materials should be able to withstand a variety of sterilization treatment of industrial clean room.
B. Biological safety clean room: mainly control the pollution of living particles to the outside world and people. The interior should maintain negative pressure with the atmosphere.
One of the biggest threats to contamination in a cleanroom is airborne molecular contaminants (AMC). These contaminants run a risk to compromising your product, process, and personnel inside the cleanroom. Some other sources of contamination can be from solvent evaporation, plasticizers from off-gassing of polymers, acidic and basic compounds that react to forms of elemental compounds. It is important to create a list of all equipment and processes that are going to be used in the cleanroom.
This list will help you narrow down an ISO classification for the space which will influence your design and constructability. Once you identify the ISO cleanroom classification, you will want to develop a hierarchy of cleanliness which will help with airflow cleanroom design and personnel flow.
