The laboratory purification project is a systematic project that applies air cleaning technology to control the living and living environment to meet the requirements of the cleanliness level of the indoor environment. It mainly includes two parts: air purification system and air supply and exhaust system. This entry is reviewed by the "Science China" Science Encyclopedia Encyclopedia Entry Compilation and Application Work Project. Introduction Laboratory purification engineering is a system engineering that uses air cleaning technology to control the living and living environment to meet the requirements of the cleanliness level of the indoor environment. It mainly includes two parts, the air purification system and the air supply and exhaust system Classification Laboratory purification projects can be divided into the following three categories according to their uses and scope of application: (1) sterile laboratory purification; (2) air purification of biological safety cabinets (biological safety cabinets); (3) high-purity electronic industry use Gas and special gas treatment Scope of application 1. Medical industry: surgical ICU ward, etc. 2. Pharmaceutical industry: GMP car drug inspection institute 3. Food processing industry 4. Cosmetics manufacturing 5. Precision machinery manufacturing 6. Scientific research and teaching 7. Other places that need to be purified
1. Market prospects When it comes to the market prospects of the domestic purification engineering industry, its market demand has broad prospects. This is because domestic industries such as biomedicine, electronic information, precision instruments, food and chemical industries are developing continuously, which has also driven the development of the purification engineering industry. It can be said that the domestic purification engineering industry is ushering in a new period of development. What needs to be pointed out here is that with the implementation of domestic medical reform and the release of GMP-2010, the demand for purification engineering in the biomedicine, food and chemical industries has been greatly promoted, and the large-scale expansion of the entire purification engineering industry has been driven. Due to the positive impact of these policies, the strong demand for purification projects in the domestic market will remain for a long time. 2. Market competition When it comes to market competition in the domestic purification engineering industry, it is mainly from price competition to value competition. Taking the purification workshop of electronic products as an example, these products are currently changing to integration, precision, miniaturization, and functionalization, so there are strict requirements on the reliability of components, and the requirements for purification workshops are becoming more and more strict. . For precision electronic components, a small amount of dust or static electricity is enough to cause a significant reduction in the yield rate, which in turn affects the company's benefits. Taking the static voltage threshold of the hard disk head as an example, it is currently within 3V, and the packaging environment is required to reach the level of Class 10 or even Class 1. To achieve integration, precision, miniaturization, and functionalization, the cost price will naturally increase, so price competition is obviously no longer applicable, but it must be turned to value competition. In short, for companies in the purification engineering industry, only with technology research and development and independent innovation capabilities can they continue to develop and not be overwhelmed by the trend of the times. Committed to cleanroom wall systems、clean room partitions and clean room windows etc.
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. two, 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 ...
