The whole solution of shower room project

In the scale and technical level of clean room construction, there is a bigger gap between China and the advanced countries. Shimizu construction company of Japan.

The new TSMCs plant in the United States has built the fourth generation pipeline cleanroom with a total area of 10000 square meters. The 0,1 μ m grade 10 cleanrooms used in China mainly rely on imports from abroad. Because the cost of high-level clean room is very expensive, the cost of 0.1 micron grade 10 clean room per square meter is as high as 10000 US dollars. In the investment of large-scale integrated circuit manufacturing equipment, clean workshop occupies a high proportion, which is incompatible with the development trend of continuous updating of integrated circuit technology and faster and faster product update cycle, which seriously restricts the development of large-scale integrated circuit technology. In recent years, the equipment and technology of submicron production microenvironment system using isolation technology developed by ASysT company in the United States and MW company in Germany have been widely used in recent years. The new cleaning technology adopts the micro environment of isolation technology in the clean workshop with 100 class cleanliness. The project unifies the workshop to purify the single person air, and reduces the investment proportion to the high-level micro environment, thus eliminating the impact of secondary pollution sources caused by operators and process equipment operation on the yield and reliability of integrated circuits. Human metabolism will produce micro dust, the human body will carry micro dust, people in the clean workshop activities will produce and emit a large number of micro dust. According to the analysis of the test results, about 80% of the workers are working in the clean workshop. The dust in and out of the clean workshop is significantly increased. When someone moves, the cleanliness is significantly deteriorated. It is confirmed that human is the main cause of the dust in the clean workshop. As the major source of micro dust and the main media in drug production, the production personnel always contact with drugs directly or indirectly, which will affect the quality of drugs. The overall solution of the shower project comes from two aspects: one is the original physical condition of the personnel. Second, personal hygiene habits. The necessity of establishing health records pharmaceutical factories have a general understanding of the health status of employees when they recruit employees. In addition, regular physical examination should be carried out for employees in the pharmaceutical factory. GMP workshop of medical devices not only has high equipment cost, complex production process, high requirements for cleanliness and sterility, but also has strict requirements for the quality of production personnel. There will be potential biological hazards in the production process, mainly including (infection risk, toxicity, sensitization and other biological reactions caused by dead bacteria or dead cells and components or metabolism to human body and other organisms, toxicity, sensitization and other biological reactions of products, and environmental effects).

Dust free room, also known as clean room, refers to an environment with low pollution level. The pollution sources here include dust, airborne microorganisms, suspended particles, and chemical volatile gases. More precisely, a clean room has a controlled pollution level, which can be determined by the number of particles per cubic meter, or by the size of large particles. Low level cleanrooms are usually not disinfected (e.g. no controlled microorganisms) and are more concerned with airborne dust. The definition of dust-free room: the air within the scope of space such as dust particles and other pollutants are removed, and a fairly clean environment is obtained. That is to say, there are very few dust particles in this environment, which is called clean room. As long as the sterile room is enough to place laboratory samples and necessary equipment, the area does not need to be too large to cause waste. If the area is too large, it will not only increase the construction cost, but also the operation and maintenance costs in the future. General microbiological testing according to the requirements of the laboratory industry need to be carried out in the sterile room, many food bacteria, microorganisms, etc. are completed in the ultra clean work of testing and testing. With the development of social science and technology, the state pays more and more attention to food safety, and the air purification project of aseptic room is also becoming more and more popular. Clean project partition wall decoration: except for the partition wall of fire compartment, all of them adopt manual rock wool board, the specific model is: the thickness of face wall steel plate is 0. 476 mm; rock wool unit weight: above 100kg / m3; material width: 1150 mm, length customized; overall thickness of plate: 50 mm; fire resistance limit: more than 30 minutes.

The international market of clean technology and equipment is very huge. By the end of 1980s and the beginning of 1990s, the sales volume of clean technology and equipment in Japan has exceeded 3.5 billion US dollars. According to the statistics of China Electronic Special Equipment Industry Association, the sales volume of eight major purification equipment factories in China was 82.17 million yuan in 1990, which was less than 100 million yuan, and reached 144.95 million yuan in 1993, accounting for 0.34% of the international market sales. However, with the rapid development of high and new technology and the development of microelectronics industry, optical fiber industry, liquid crystal display industry, optoelectronic device industry, bioengineering and pharmaceutical industry, the potential huge market of clean technology products in China is increasing at the rate of 40% ~ 50% every year. The static electricity resistance of steel plate can be greatly reduced. Anti static color steel wall panel has obvious effect on dissipating static load. The resistance value of color steel wall panel surface in antistatic motor room is 5-8 ohm of 10, and static charge is reduced to less than 1 second, so as to ensure the anti-static performance of anti-static wall panel and the safety of users. The use of anti-static materials for dust-free workshop decoration is not only the basic design of anti-static, but also an effective method, which can reduce the electrostatic hazard in the dust-free workshop to a low level. In the later stage of the daily maintenance of dust-free workshop, there are many useful anti-static tricks. For example, good control of dust-free workshop humidity within a reasonable range, reasonable humidity can reduce the generation of static electricity. The use of ion air gun, ion head, ion bar and other facilities to prevent static electricity within a certain range. Anti static container is used in single air shower room. This kind of container has good conductivity and can effectively prevent the generation of static electricity. Of course, if possible, it can also be placed in a metal container or packed with metal foil. Operators can wear anti-static hand strap, which should have good grounding performance and is also a good anti-static measure. The cleanliness, temperature and humidity of the clean room should be monitored and tested, and the excessive parameters should be adjusted in time. Wash basin, dryer, alcohol spray sterilizer, to a large extent, the external dust particles isolated from the purification workshop. The oil injection and purification workshop adopts the double blow shower room with mother and child door. Inlet electrostatic eliminator.
