Hunan Purification Engineering: Several Requirements for Cleanroom Decoration

2024-09-03 2351

The architectural decoration of the dust-free workshop area and control area should be easy to clean and protect, with a flat surface and no particulate matter falling off. According to standard requirements, there are generally several requirements that indoor decoration should meet.

The enclosure structure and interior decoration materials of the dust-free workshop should be made of materials with excellent airtightness and minimal self deformation under changes in temperature, humidity, etc; The exterior of the wall and ceiling should be smooth, flat, dust-free, corrosion-resistant, impact resistant, and easy to clean. In order to minimize the accumulation of dust on the exterior of the cleanroom and make it easy to clean, it is necessary to prevent or reduce concave and convex surfaces in the building structure. The joints between walls and the ground, walls and ceilings, and walls and walls should not be made into general right angles, but should be made into rounded corners with a radius greater than or equal to 50mm. The color of the wall coating should be harmonious, elegant, and clean to facilitate the flashing of pollutants on the wall. Similarly, the ground should also be flat, seamless, durable, corrosion-resistant, impact resistant, free from static electricity accumulation, and easy to remove dust and clean.

In order to prevent particles and microorganisms from contaminating the cleanroom in the skill interlayer, the walls and ceilings should be plastered (highly plastered). If it is necessary to replace the filter with the best effect in the skill compartment, the walls and ceilings inside the compartment should also be coated with paint. The exterior decoration of the air supply duct, return air duct, and return air trench should be compatible with the entire air supply and return system and easy to clean and disinfect.

Doors, windows, and interior walls should be flat, and window sills should be avoided as much as possible. The number of layers of external windows and the structure of doors and windows should be comprehensively considered based on the degree of outdoor air pollution, the design temperature and humidity inside and outside the room, the pressure difference inside and outside the room, and the cleanliness of the room. The structure should be able to seal the air and water vapor, making it difficult for pollutants to enter from the outside and preventing condensation on the inside and outside of the room. In order to prevent cross contamination within the clean area, the gaps between the interior doors, windows, and partitions of rooms with different cleanliness levels should be sealed. The shape of doors and windows should be simple and no threshold should be set for easy cleaning.

To ensure the cleanliness of the factory building, the clean area should have windows sealed. Double layered windows should be installed between air-conditioned and non air conditioned areas, with at least one fixed window in between. In addition, the connecting doors between cleanrooms of different cleanliness levels should be sealed, flat, and have a simple shape, and the doors should open in the direction of higher cleanliness levels.
