Clean room, also known as clean room or clean room. It is the basis of pollution control. Without a workshop, mass production of pollution-sensitive parts is impossible. A dust-free workshop is defined as a room equipped with air filtration, distribution, optimization, construction materials and equipment, in which specific regular operating procedures are used to control the concentration of airborne particulates, so as to achieve an appropriate level of particulate cleanliness. A dust-free workshop refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting, and static electricity. It is controlled within a certain range of demand, and is given a specially designed production workshop. This shows that the dust-free workshop is an extremely clean workplace.
Then why do people need to wash their hands and disinfect before entering the air shower? The air shower room is installed in the place where people enter and exit the dust-free workshop. This is the first gate for personnel to enter the clean room. The working principle of the air shower room: The air shower room adopts the form of jet air flow. The air filtered by the pre-filter is pressed into the static pressure box, and then the clean air flow blown out through the air outlet surface. When passing through the work area at a certain wind speed, the dust particles and biological particles of the people and objects themselves are taken away to achieve cleanliness the goal of.
People are the biggest source of pollution in clean rooms. To obtain the air cleanliness required by the production environment, the purification of personnel is very necessary.
(1) Establish personnel health files. Develop good hygiene habits, wash hands, bathe, cut nails, haircut frequently, change clothes frequently, and strictly prohibit smoking.
(2) Personnel purification Personnel entering the clean room must go through a series of purification procedures. Personnel decontamination should be carried out step by step, with a reasonable procedure, during the decontamination process, to prevent the cleaned part from being contaminated by the dirty part.
