Purification workshop engineering, also known as clean room or clean room. It is the foundation of pollution control. Without a clean room, mass production of contamination-sensitive parts is impossible. In fed-std-2, a cleanroom is defined as a room with air filtration, distribution, optimization, construction materials and devices, where specific regular operating procedures are used to control airborne particulate concentrations to achieve an appropriate level of particulate cleanliness .
In order to obtain a good cleaning effect in the purification workshop project, not only should we focus on taking reasonable air-conditioning purification measures, but also require corresponding measures in technology, architecture and other professions: not only reasonable design, but also careful construction that conforms to specifications Installation, as well as the correct use of clean rooms and scientific maintenance management. In order to obtain a good effect in the clean room, many domestic and foreign literatures have expounded it from different angles. In fact, it is difficult to achieve ideal cooperation between different professions, and it is difficult for designers to grasp the quality of construction and installation, as well as the use and management, especially the latter. As far as clean room purification measures are concerned, many designers, or construction parties, often do not pay enough attention to its necessary conditions, resulting in unsatisfactory cleaning effects.
1. Within a certain space, remove the pollutants such as particulates, harmful air and bacteria in the air, and control the indoor temperature, cleanliness, pressure, airflow speed and airflow distribution, noise and vibration, lighting, and static electricity within a certain requirement. Engineering disciplines in scope. The room specially designed by the purification project has the performance of maintaining the cleanliness, temperature, humidity and pressure of the original set requirements no matter how the external air conditions change.

1. Negative ion purification: Negative ions are a kind of negatively charged gas ions in the air, which adsorb the suspended particles with positively charged ions, neutralize them into non-charged particles and settle down to purify the air. It can be said that the purification of air by negative ions is to reduce the concentration of suspended particulate matter in the air, but it cannot kill bacteria, viruses, or decompose pollutants. Air is made up of countless atoms and molecules. When molecules or atoms in the air lose or gain electrons, they form charged particles called ions; those with positive charges are called positive ions, and those with negative charges are called negative ions.
2. Photocatalytic air purification technology: The central air-conditioning photocatalytic air purification and sterilizer module manufactured by this technology is composed of coated titanium dioxide fine wire filter, primary and medium-efficiency filter, nano-titanium dioxide photocatalytic chamber, intelligent control system, etc. factor composition. It has multi-channel procedures from primary filtration to complete purification, which can quickly kill viruses and bacteria in the air in a short time, remove pollution, smoke and odor. It is a high-efficiency multi-factor air purifier and disinfector for preventing respiratory infectious diseases, preventing airborne viruses and bacteria, eliminating smoking hazards and degrading indoor pollution. Nanomaterials photocatalytic environmental pollution control technology is the most effective advanced technology for the control of low-concentration organic polluting gases, disinfection and sterilization generally recognized internationally. It has the characteristics of mild reaction conditions, economical and comprehensive treatment of bacteria, viruses and pollutants. .
3. Industry application of purification workshop
A. Purification workshop engineering is a basic supporting industry with a very wide range of applications. It is currently used in many industries such as bioengineering, precision manufacturing, medicine and health, electronic information, semiconductors, optoelectronics, aerospace, and automotive spraying. According to the industry The precision and dust-free requirements of different grades are also quite different.
B. In addition, biochemical laboratories and high-precision nanomaterials production workshops have higher requirements on the level. The development of IoT chips will be a major direction of future demand. At present, the highest level is the aviation warehouse of aerospace, which basically belongs to level 1, belongs to a special field, and has a relatively small area.
C. With the development of electronic components in the direction of miniaturization, the LCD panel has been upgraded to the eighth generation, and the industry demand is very huge.
