When it comes to clean room construction, the first thing to do is to arrange the process and building planes reasonably, and then to choose the building structure and construction materials that meet the characteristics of the clean room. The location of the clean room construction should be selected based on the local energy supply background. Then divide the air conditioning purification system and exhaust system, and finally choose reasonable air purification equipment. Whether it is a new or renovated clean room, it must be decorated according to relevant national standards and specifications.
1. The clean room system consists of five parts:
(1). To maintain the ceiling structure system, rock wool sandwich wall panels and glass magnesium sandwich ceiling panels are commonly used.
(2). Floor structure usually is high-raised floor, epoxy floor or PVC floor.
(3). Air filtration system. The air passes through a three-stage filtration system of primary filter, medium filter and hepa filter to ensure air cleanliness.
(4). Air temperature and humidity treatment system, air conditioning, refrigeration, dehumidification and humidification.
(5). People flow and material flow in clean room system, air shower, cargo air shower, pass box.
2. Installation of equipment after clean room construction:
All maintenance components of the prefabricated clean room are processed in clean room according to the unified module and series, which is suitable for mass production, with stable quality and rapid delivery. It is maneuverable and flexible, and is suitable for installation in new factories as well as for the clean room technology transformation of old factories. The maintenance structure can also be combined arbitrarily according to process requirements and is easy to disassemble. The required auxiliary building area is small and the requirements for earth building decoration are low. The airflow organization form is flexible and reasonable, which can meet the needs of various working environments and different cleanliness levels.
3. Clean room construction:
(1). Partition wall panels: including windows and doors, the material is sandwich panels, but there are many kinds of sandwich panels.
(2). Ceiling panels: including suspenders, beams, and ceiling grid beams. The materials are generally sandwich panels.
(3). Lighting fixtures: Use dust-free special lamps.
(4). Clean room production mainly includes ceilings, air conditioning systems, partitions, floors, and lighting fixtures.
(5). Floor: high-raised floor, anti-static PVC floor or epoxy floor.
(6). Air conditioning system: including air conditioning unit, air duct, filter system, FFU, etc.
4. The control elements of clean room construction include the following aspects:
(1). Control the concentration of floating dust particles in air in dust free clean room.
(2). Control of temperature and humidity in clean room.
(3). Pressure regulation and control in clean room.
(4). Release and prevention of static electricity in clean room.
(5). Control of pollutant gas emissions in clean room.
5. Clean room construction should be evaluated from the following aspects:
(1). The air filtration effect is good and can effectively control the generation of dust particles and cause secondary pollution. The air temperature and humidity control effect is good.
(2). The building structure has good sealing, good sound insulation and noise isolation performance, solid and safe installation, beautiful appearance, and smooth material surface that does not produce or accumulate dust.
(3). The indoor pressure is guaranteed and can be adjusted according to specifications to prevent indoor air cleanliness from being interfered by external air.
(4). Effectively eliminate and control static electricity to protect the quality and safety of production in dust free clean room.
(5). The system design is reasonable, which can effectively protect the operating life of the equipment, reduce the frequency of fault repairs, and make the operation economical and energy-saving.
Clean room construction is a kind of multi-functional comprehensive work. First of all, it requires the cooperation of multiple professions - structure, air conditioning, electrical, pure water, pure gas, etc. Secondly, multiple parameters need to be controlled, such as: air cleanliness, bacterial concentration, air volume, pressure, noise, illumination, etc. During clean room construction, only professionals who comprehensively coordinate the cooperation between various professional contents can achieve good control of various parameters that need to be controlled in clean room.
Whether the overall performance of clean room construction is good or not is related to the quality of the customer's production and the cost of operation. Many clean rooms designed and decorated by non-professionals may have no problems with air cleanliness control, air conditioning temperature and humidity, but due to a lack of professional understanding, the designed systems have many unreasonable and hidden defects. The control requirements required by customers are often achieved at the expense of expensive operating costs. This is where many customers complain. Super Clean Tech has been focusing on clean room engineering planning, design, construction and renovation projects for more than 20 years. It provides one-stop solutions to clean room project in different industries.
