With the rapid development of my country's purification industry, clean rooms in dust-free workshops have been widely used in high-tech industries such as microelectronics, optical and magnetic technology, biological engineering, electronic equipment, precision instruments, aerospace, food industry, cosmetics industry, scientific research and teaching. In all walks of life. Because the dust-free workshop is in the temperature and humidityAir cleanlinessThe huge advantage of this aspect, its importance is gradually recognized and accepted by people. Dust-free workshops of various scales and different cleanliness levels are playing an increasingly important role in various industries and have made very important contributions to improving product quality and developing high-tech products.

The industry's requirements for the production environment are getting higher and higher, so the dust-free workshop is born. It refers to removing particles, harmful air, bacteria and other pollutants in the air within a certain space, and controlling indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting, and static electricity. A specially designed room within a certain range of needs. That is, no matter how the external air conditions change, the room can maintain the original set requirements of cleanliness, temperature, humidity, and pressure.

The purification workshop is also divided into the following levels:

Level 1 This level of clean room is mainly used in the microelectronics industry for manufacturing integrated circuits, and the precision requirements for integrated circuits are sub-micron.

Class 10 This class of clean room is mainly used in the semiconductor industry with a bandwidth of less than 2 microns.

Many people at level 100 believe that this level of clean room is the most commonly used and therefore the most important clean room. People often mistakenly call the level 100 clean room as a sterile room to explain the \"sterile\" or \"Dust-free\" environmental requirements, the 100-level clean room can be used for aseptic manufacturing processes in the pharmaceutical industry, etc. This dust-free workshop is widely used in the manufacture of implants in the body, surgical operations, including transplantation operations, and integration The manufacture of organs, isolation treatment of patients who are particularly sensitive to bacterial infections, such as isolation treatment after bone marrow transplantation.

Class 1000 This class of clean room is mainly used for the production of high-quality optical products, as well as for testing, assembling aircraft gyroscopes, and assembling high-quality miniature bearings.

The 10,000-class dust-free workshop is used for the assembly of hydraulic equipment or pneumatic equipment. In some cases, it is also used in the food and beverage industry. In addition, the 10,000-class dust-free workshop is also very commonly used in the medical industry.

Class 100,000 clean rooms are used in many industrial sectors, such as the manufacture of optical products, the manufacture of smaller components, the manufacture of large electronic systems, the manufacture of hydraulic or pneumatic systems, the production of food and beverages, and the medical and pharmaceutical industries. This level of clean room is often used.

However, the design requirements of the clean room should meet the requirements of the product production process and the air cleanliness level.

When designing the space, the Shandong snyli air filter manufacturer considers the relationship between the production clean area and the related auxiliary production area, and must make the space layout effective and flexible. For the general clean shed, it is arranged on the upper part of the ceiling or under the floor. Supply air, return air and exhaust pipes, as well as various water, gas, and electrical pipelines, etc., need to set up the necessary space in a dust-free workshop with vertical unidirectional flow. The first step is to choose the air flow pattern and purify the air conditioning system. Reasonably and effectively arrange the clean room space on the premise of the form, air conditioner and air filter: in the clean room design, especially the one-way flow clean room design, the selection of air flow patterns, air filters, and purification air conditioning equipment The choice of layout plan is the main factor to determine the space layout of the clean room; in general architectural design, the air conditioner is the auxiliary equipment of the building. It only supplements and perfects the functional equipment of the building, but the purification of air-conditioning equipment in the clean workshop is to achieveAir cleanlinessThe main function equipment.
