Low price and high quality clean room in 2016

Definition of cleanse:
Smear exists during processing or handling objects will affect the success rate, while controlling the smear on the processing object will increase the success rate. Technology of cleanse and tarnish control, usually called as tarnish control in international, is a technique to control such smears (also including treatment and isolation of harmful substances in the processing or handling objects).       Manipulation of clean air:
Air from outdoor is processed by early effect segment, mixed with indoor return air, and then filtrated by middle effect segment, high effect segment to clean room, to control the number of particles in the air below a certain number.
Air can also be manipulated by heating, cooling, humidification, dehumidification, sterilization and et al, to receive certain state like sterile, constant temperature and humidity.
According to the clean-level, indoor air can be organized in a manner laminar, turbulent flow and mixing.   Clean possession of state:
Empty: Facilities have been completed, all connected to power supply and run, but no production equipment, materials and staff
Dynamic: Facilities have been completed, production equipment has been installed, operation under agree ment of business and vendors agree, but no staff.
Static: Facilities run under stated condition, the presence of stated person and work under promissory state.      A Cleanroom or clean room is an environment, typically used in manufacturing or scientific research, that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. More accurately, a cleanroom has a controlled level of contaimination that is specified by the number of particles per cubic meter at a specified particle size. To give perspective, the ambient air outside in a typical urban environment contains 35,000,000 particles per cubic meter in the size range 0.5um and larger in diameter, corresponding to an ISO9 cleanroom, while an ISO1 cleanroom allows no particles in that size range and only 12 particles per cubic meter of 0.3um and smaller.
