Cleanroom profile:
Cleanroom space refers to a certain range of fine particles in the air, harmful air, bacteria and other pollutants removed, and the indoor temperature, cleanliness, room pressure, air speed and air distribution, noise, vibration and lighting, static control in a within the range of needs, while being given specially designed room. That is regardless of how changes in the external air conditions, its interior can have all the requirements to maintain the cleanliness of the originally set temperature, humidity and pressure characteristics and other properties of.

The main role of the clean room is to control products (such as silicon chips, etc.) in contact with the atmosphere and clean live temperature and humidity, so that the product can be in a good environment space production, manufacture, this space we call the clean rooms. According to international practice, Clean purification level is mainly based on the particle diameter is larger than the number of particles per cubic meter of criteria for the classification of air to regulations. That is called not 100% clean of any dirt, but to control in a very small amount of units. Of course, the particles of dust standards comply with this standard with respect to our common dust is already a little small, but in terms of the optical structure, even if it is a little bit of dust will have a very large negative impact, so the optical construction products , dust is an inevitable requirement.

Cleanroom importance:
Clean room cleanliness is often affected by the air flow, in other words, moving the dust of that is people, machines compartments, structures, etc. generated by the gas flow dominated by diffusion. Cleanroom system utilizing HEPA, ULPA filtered air, the dust collection rate of 99.97 ~ 99.99995% as much, so after this filter the air can be said to be very clean. However, in addition to the clean room of people, there are machines and other sources of dust, the dust diffusion occurs once, that can not be kept clean space, so you must use the dust airflow will occur rapidly exhausted to the outside.

Optical microelectronic decontamination structural materials:
1. purification plant wall, the top sheet generally use more steel plate 50mm thick sandwich of color, which is characterized by beautiful, strong rigidity. Arc corner, doors, window frames and other general uses special aluminum oxide manufacture.
2. The ground can be used epoxy artesian Ping Ping or high wear-resistant plastic flooring, anti-static requirements, the choice of anti-static type.
3. The return air duct made of hot galvanized plate, attached to purify the insulation effect good flame retardant foam plastic plate PF.
4. HEPA stainless steel frame, beautiful and clean, perforated metal mesh plate with aluminum paint, no rust dust free, should be clean.

Design:
Optical microelectronics industry purification engineering design analysis for conventional electronic factory clean room air-conditioning design, should be based on the production process requirements and economic conditions Party to choose which electronic factory air-conditioning design programs to meet the requirements of the production process as a prerequisite. Based on past experience, for demanding air conditioning program can choose to focus on modular air handling units; for less demanding, but also a low initial investment, you can choose Guiji + FFU. In short, the specific program selected according to specific circumstances.

Sterile operating room Note:
1. Safety Precautions strict aseptic technique to prevent microbial contamination; operator into a sterile room should turn off the UV lamp.
2. sterile room should be equipped with inter-aseptic and buffer between aseptic cleanliness should reach 10,000, the indoor temperature is maintained at 20-24 ℃, humidity of 45-60%. Clean Bench cleanliness should reach 100.
3. sterile room should be kept clean, non-stacked debris, to prevent contamination. Sterilization of equipment and media to prevent all contamination has polluter should stop using.
4. The sterile room should be regularly sterilized with a suitable disinfectant clean to ensure the cleanliness of the sterile room to meet the requirements.
5. The need to bring all the items instruments, equipment, plates and other sterile room use, shall be tightly bandaged, and should be subject to appropriate sterilization method.
6. Before entering the sterile room staff must wash their hands with soap or disinfectant disinfection, and then replace the special clothes, shoes, hats, masks and gloves in between the buffer (or with 70% ethanol wipe his hands again), before entering the no Bacteria chamber operation.
7. sterile room must turn on the UV light irradiation sterilization sterile room 30 minutes before use, and at the same time open the station clean hair. Operation is completed, should be cleaned sterile room, and then 20 minutes of UV light irradiation sterilization.
8. The test sample before the test, the packaging should be kept intact, not open, to prevent contamination. Before the test, with 70% alcohol swab to the outer surface.
9. Where goods with live bacteria, must after disinfection, rinse under the tap to prohibited pollution sewer.
Decontamination schematic
Return air: also known as suction outlet, air vents, air conditioning piped middle to the outside air nozzle.
Outlet: means an intermediate air conditioning piped to the indoor air nozzle.
Aseptic transfer positions: the transfer window, it as a clean room auxiliary equipment, mainly used to transfer clean area and clean area, a non-clean area and clean area between the small items in order to reduce the number of clean room door maximize the reduction of pollution in clean areas.
Local clean room: the clean studio, it has a variety of clean grade and can be designed according to the space with the use of demand, so it is easy to install and easy to use elastic and the short construction period and a shift of its main features.
Air shower disinfection area: that air shower, it is the person or cargo entering the clean area by the fan through the air shower nozzle through efficient filter clean strong winds in addition to the person or object surface adsorption dust of a universal strong local purification equipment.
Epoxy anti-static ground: namely epoxy floor paint, which has strong acid and alkali resistance, abrasion resistance, pressure, impact resistance, mildew, waterproof, dustproof, anti-slip and anti-static, electromagnetic properties, color bright and diverse, easy to clean. It uses a one-time coating process, no matter how much of the area, does not exist in the connection joints, but also a dust-free material, with strong adhesion, abrasion, hardness and other characteristics.
Clean Bench: that ultra-clean table, to supplement the exhaust air vents, the same volume of air from the room air supplemented by operating the port. The air will not enter the operating area, but form an air barrier. Widely used in medicine, bio-pharmaceuticals, food, medical science experiments, optics, electronics, sterile room experiment, sterile microbiological testing, plant tissue culture inoculation and other needs of local clean research and production departments sterile work environment.
