First, the layout of the Dongguan clean room requirements The Dongguan clean room is an independent space in terms of layout. A ring-shaped sealed corridor is set up outside the workshop, which provides a buffer zone between the clean area and the outside world, which can prevent external pollution and is relatively energy efficient. Doors and windows in the factory building should be flat on the inner wall surface without window sills. The number of layers and the structural form of the outer window must fully consider the sealing of air moisture, so that pollution particles cannot easily penetrate from the outside. In order to prevent condensation between indoor and outdoor temperature differences, the gaps between doors and windows between rooms with different cleanliness should be sealed. Door and window materials should be selected with good weather resistance, small natural deformation, small manufacturing error, good air tightness, simple modeling, not easy to accumulate dust, easy to clean, and no threshold for door frames. The doors and windows of clean workshops should be made of metal or metal-coated plastic materials. Wooden doors and windows should not be used to avoid long-term exposure to moisture and bacteria. The windows on the outer wall should be flat with the inner wall surface, the windowsill is beveled or no windowsill is left, and it is a double-layer fixed window to reduce energy loss.
Second, Dongguan clean room workshop wall decoration requirements Dongguan clean room decoration wall should be smooth, flat and dust-free, corrosion-resistant, harmonious colors, easy to identify pollutants, interior wall coatings must be anti-mold, anti-static, avoid glare Can withstand cleaning and disinfection of materials. An arc with a radius of 50 mm should be made at the intersection of the wall and the ground to reduce dust accumulation and facilitate cleaning. Anti-collision railings should be set up on the walls of vulnerable places such as transportation corridors to prevent dust from falling off due to vibration of decoration materials.
Three = Dongguan dust-free workshop floor decoration requirements The Dongguan dust-free workshop floor decoration should be flat, seamless, wear-resistant and corrosion-resistant, not easy to collect static electricity, and easy to clean the overall floor. The design can use in-situ terrazzo ground, the diameter of the stones used should be between 6-15mm. Among them, the copper strips must be used for the separation bar, and glass bars must not be used. Currently, epoxy self-leveling floor is used, which is a resin composite floor. Its characteristics are solvent-free, non-toxic, tasteless, no seams, and self-leveling. Can achieve mirror decorative effect, seamless connection, oil resistance and acid, alkali, salt chemical solvents. It has the characteristics of anti-static, small dust generation, abrasion resistance and impact resistance, but the cost is high. Most of them are used on the floor of production workshops in electronics, medicine, blood products and other industries that require high cleanliness, beautiful appearance, dust-free and sterile. Epoxy self-leveling floor has a service life of more than 1mm and can generally be used for more than 6 years. A moisture-proof layer should be laid under the above ground floor cushion, and the concrete depot line should not pass through the clean area.
4. The air supply ducts and lamps of the Dongguan clean room must be arranged in the technical mezzanine. In order to ensure the indoor cleanliness of the Dongguan clean room, all the air ducts and lamps must be arranged in the technical mezzanine. Most pharmaceutical companies now use colored steel sandwich panels to seal the ceiling. The color steel sandwich panel has the characteristics of light weight, high overall strength, good integrity, and low thermal insulation and dust generation, which is more suitable for GMP production plants. However, the ceiling must be fixed to the structural body and cannot be mixed with equipment and pipeline supports. The ceiling should be smoothly connected to the wall. The ceiling and return air duct openings must be reliably closed. After the ceiling is installed, a light inspection is required to ensure seamless clearance. According to process requirements, maintenance walkways should generally be provided in the technical mezzanine to facilitate pipeline maintenance and filter replacement. Technical interlayer walls and ceilings need paint finishes.
