A Brief History of the Development of Clean Room Workshops


The cleaning technology of the clean room workshop is not a new concept. Maybe everyone knows about the clean room knowledge on the Internet from different angles. For example, if you make clean room clothing, the human body is the largest source of pollution in the clean room. A qualified clean Room clothing plays a vital role in maintaining a clean room. Research on the evaluation method of clean clothing, and guide the production, design and purchase of clean clothing (clean performance, electrostatic performance, durability and comfort). It is of great significance for the workshop to study clean clothes as an entrance; for example, as a purification equipment factory, it will provide assembly clean rooms (clean level is 100 to 300,000), a series of purification workbenches, air shower rooms, and efficient ventilation. Mouth, laminar flow hood, sampling car, primary, middle and high efficiency air filter, aluminum alloy tuyere, diffuser, regulating valve, muffler, series of multi-functional air conditioners and all products and accessories needed for air conditioning purification. There are many angles to explore the cleaning technology of dust-free workshops. A brief history of the development of clean plants. After World War I, the United States' gyroscope manufacturing industry first raised the issue of purification. In order to eliminate the pollution of aviation instrument small bearings and gears by heavy powder in the air, it built the most primitive clean plant. Twenty years after World War II and World War I, military science and technology have advanced by leaps and bounds. The American Antonio missile company has found that the average 10th product of inertial guidance gyroscopes assembled in ordinary workshops will be reworked 120 times After controlling air pollution, the rework rate was reduced to 2 times. In the gyro bearing with a speed of 12000rpm, the dust-free life was 100 times different from that of 1000 gyroscopes (∮3um). , Computer, transistor, etc., put forward higher requirements for air pollution control. After the Second World War, the United States formulated the petite rocket development plan. After repeated explorations by scientists, high-efficiency filters were born and made the first leap in air purification technology. In the 1950s and 1960s, Britain, Japan, the Soviet Union, and China successively built clean workshops, and compiled design and construction specifications for clean workshops, which imposed strict requirements on air purification, building materials, decoration materials, and people ’s pollution to the workshop. . After a century of development, the design and construction of clean workshops have been widely used in machinery, instruments, electronics, aerospace, optics, pharmaceuticals, chemistry, food industry and medical, laboratory, from 100 to 100,000 clean workshops. 2. The core of the "clean concept" of the clean plant The core of the "clean concept" of the clean plant is controlling dust. From the beginning of the design of the clean workshop to the construction and decoration, as well as the elements of air purification, air flow organization, and personnel purification in Dongguan clean room, all around this core. Clean factory cleaning is also inseparable from this core. III. Clean plant cleaning technology Although the clean plant construction has a high degree of protection for dust control, building decoration materials, facilities and equipment, production processes, and personnel will all generate dust and dust accumulation to varying degrees, especially 10,000 levels and 100,000. Grade clean factory (due to construction cost), the following points are included in the clean factory cleaning technology around the source of dust and dust accumulation: 1. Roof: Roof materials are mostly smooth surfaces, such as color steel plates, plastic plates, aluminum plates, and gusset plates. The dust-free cloth with strong adsorption force wipes the surface, and it can be used with tools such as telescopic rods and tiger clips. For irregularities and inferior corners, ultra-dust industrial vacuum cleaners can be used for vacuuming. 2. Wall surface: Wall materials are mostly smooth materials, such as glass, color steel plates, plastic plates, aluminum plates, gusset plates, and stainless steel plates. You can use a dust-free cloth and a dust-free wiper to wipe the surface. With glass scraper, telescopic rod, tiger clip and other tools to use, handy. For irregularities and inferior corners, ultra-dust industrial vacuum cleaners can be used for vacuuming. 3. Floor: Polyurethane paint, epoxy resin, artificial leather, and terrazzo are mostly used for the floor material. In order to effectively prevent dust from the floor material and improve the life of the floor material, antistatic accumulated wax water can be used for waxing.
