What should be paid attention to during the decoration and construction of the dust-free workshop? The decoration requirements of the floor and wall surface of the dust-free workshop
A clean room, also known as a clean room or a clean room, is the basis for pollution control. The use of a clean room, no matter how the external air conditions change, can maintain the cleanliness, temperature, humidity and pressure of the original set requirements. In the decoration process of the clean room, there are certain requirements for both the ground and the wall. If the requirements are not met, it is likely to have a certain impact on the use of the clean room. So what should I pay attention to during the decoration and construction of the dust-free workshop? What are the decoration requirements for the floor and wall surface of the dust-free workshop? The following sz-pharma will introduce to you and discuss together: 1. Attention should be paid to the decoration and construction of the dust-free workshop The following aspects: 1. The inner wall of the air duct of the purification air-conditioning system is not clean, the connection has loopholes, and the air leakage rate is too large; 2. The surrounding structure of the color steel plate is not good, the sealing measures of the clean room and the technical interlayer are not appropriate, and the sealing effect of the airtight door is poor. ; 3. The decorative profiles and process pipelines form dead corners and dust accumulation in the dust-free pharmaceutical cleanroom; 4. Individual positions are not constructed according to the design requirements and cannot meet the relevant requirements; 5. The quality of the sealant used is not good enough, easy to fall off, and deteriorate; 6. 7. The inner wall weld is not formed during welding of stainless steel sanitary pipes such as process purified water and injection water; 8. The action of the check valve in the air duct fails. Air inversion causes pollution; 9. The installation quality of the drainage system is not up to standard, and the pipe racks and accessories are easy to accumulate dust; 10. The pressure difference setting of the dust-free pharmaceutical cleanroom is unqualified and fails to meet the production process requirements. 2. Wall decoration requirements of dust-free workshop: 1. The decoration wall of dust-free workshop should be smooth, flat and dust-free, corrosion-resistant, harmonious in color, and easy to identify pollutants. The interior wall paint must be anti-mildew, anti-static, and avoid glare. And resistant to brushing with cleaning and sterilizing materials. 2. 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 installed on the walls of easily-collisable places such as transportation corridors to prevent dust from falling off due to vibration of decoration materials. 3. Floor decoration requirements of dust-free workshop: 1. The decoration of dust-free workshop requires the characteristics of wear resistance and corrosion resistance, smoothness, no gap, not easy to accumulate static electricity, and easy to clean. 2. In the construction process of the dust-free workshop, the ground of cast-in-place terrazzo is used, and the diameter of the stone should be kept at 6-15mm. And it must be separated by copper strips, absolutely not glass strips. 3. At present, most of the construction uses epoxy artesian floor, a kind of resin composite floor, which has the advantages of no solvent, non-toxic and tasteless, no joints, artesian level and irreplaceable advantages. The effect after decoration can achieve the effect of mirror decoration. , Seamless connection, oil resistance and acid, alkali, salt chemical solvent and other characteristics. At the same time, it also has anti-static, small dust generation, wear resistance and impact resistance, and can be used for more than 6 years with a service life of more than 1mm thickness. 4. A moisture-proof layer should be laid under the floor cushion, and the concrete sub-silo line should not pass through the clean area.
At the same time, as the recent research of PHARMA shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
