Clean room technology application in different industry

With the development of technology, especially in the semiconductor industry, many production steps must be carried out under clean room conditions. (Purification Engineering Technology) The application of clean rooms is becoming more and more important. Now I will introduce the application of purification engineering technology in various fields!

In the microelectronics industry, those engaged in precision production and scientific experiment activities such as precision instruments, LEDs, liquid crystals, etc., must achieve a certain dust-free production environment for production needs, and specialize in the construction of dust-free workshops, dust-free workshops or dust-free rooms A technology produced by the needs of the United States, it is clean technology. It is an emerging technology born to meet the requirements of precision, miniaturization, high purity, high quality and high reliability in experimental research and product processing. The term and concept of cleanroom originated from European medicine in the 1860s. At that time, the understanding was limited to the working environment of sterilization treatment such as treatment rooms and operating rooms that can control the infection rate of wounds after spraying and disinfection. Although the modern clean room uses this term, it is fundamentally different from the original concept in definition and connotation. The modern clean room has formed a specialized technology, and its history is only half a century.

—、Dust-free workshop engineering technology (what is dust-free workshop engineering)

Through the various facilities and strict management of the clean room engineering technology, the indoor particle content, air flow, pressure, etc. are also controlled within a certain range. This kind of room space is called a clean room.

2. Application of engineering technology in dust-free workshop

1 Microelectronics Industry

The microelectronics industry is currently the most demanding industrial clean industry for clean rooms. In addition, the production of liquid crystals and optical fibers in modern industries also has requirements for cleanliness.

2Pharmaceutical Industry

(1) Pharmaceutical production my country's "Management of Pharmaceutical Production" (also known as GMP) has been implemented nationwide, and different cleanliness levels corresponding to the process have been proposed for the production environment. In addition to limiting the size and content of dust particles in the air, there are also clear restrictions on biological particles (the number of bacteria).

(2) Hospital leukemia treatment rooms, burn wards, and surgical operating rooms, according to the conditions, use corresponding clean technology to prevent bacterial infection in the air, and play an environmental protection role for treatment.

(3) Medical science experiments should also have a clean environment for the breeding of laboratory animals, genetic engineering and other disciplines in order to achieve effective results.

3 The aseptic packaging of food is also superior to high-temperature sterilized canned food in maintaining food color, aroma, taste and nutrition. 4 Others, such as aerospace industry, precision machinery industry, instrumentation industry, fine chemical industry, etc., all use clean technology.
