Analysis of Reasons for Non - compliance of Cleanliness in Clean Factories
2024.10.28
In modern industrial production, especially in industries with extremely high environmental requirements such as semiconductors, pharmaceuticals, and food, the cleanliness of clean factories is of crucial importance. However, sometimes we may encounter situations where the cleanliness of clean factories does not meet the standards, which not only affects product quality but may also lead to production delays and increased costs. Guangzhou Kunling Purification Equipment Co., Ltd., as a professional supplier and service provider of purification equipment, has in - depth research and rich experience in the reasons for non - compliance of cleanliness in clean factories. Today, we will analyze in detail the main reasons for you.
I. Personnel Factors
1. Improper Personnel Access Management
- In a clean factory, personnel are one of the largest sources of pollution. If personnel do not follow the prescribed procedures when entering or leaving the clean area, such as not changing into clean clothes, not passing through the air shower or washing and disinfecting their hands, a large amount of dust, bacteria, and microorganisms will be brought into the clean area, thus affecting the cleanliness.
- For example, some workers may not take the air shower seriously when entering the clean area in order to save time, causing the dust and impurities carried on their bodies to enter the workshop.
2. Non - standard Personnel Operations
- The operation behaviors of workers in the clean area also have an impact on the cleanliness. For example, frequent walking, large - scale movements, and unnecessary conversations during the production process can cause air disturbance, making the originally settled dust particles re - suspend in the air and reducing the cleanliness.
- In addition, failure to pay attention to cleaning when operating equipment or generating dust during material handling are also common reasons for non - compliance of cleanliness.
II. Equipment Factors
1. Failure of Purification Equipment
- The purification equipment in a clean factory is the core facility for maintaining cleanliness. If fan filter units (FFU), high - efficiency particulate air (HEPA) filters, ultra - high - efficiency particulate air (ULPA) filters, etc. malfunction, such as filter blockage, fan damage, or poor sealing, they will not be able to effectively filter pollutants in the air, resulting in a decrease in cleanliness.
- For example, if the filter has not been replaced for a long time, the filtering efficiency will decrease, and dust and other impurities will penetrate the filter and enter the clean area.
2. Leakage of Production Equipment
- If the production equipment used in the process has leakage problems, such as chemical gas leakage or dust leakage, it will directly pollute the air in the clean factory and affect the cleanliness. Especially in some industries involving chemical reactions or powder processing, equipment leakage problems are more prominent.
- For example, in the active pharmaceutical ingredient synthesis workshop in the pharmaceutical industry, if the reactor is not properly sealed, harmful gases and dust may leak, seriously affecting the cleanliness.
III. Material Factors
1. Pollution Brought by Materials
- If the materials entering the clean factory have not undergone strict cleaning and disinfection treatment, they may carry a large amount of dust, microorganisms, and other pollutants. For example, the surface of raw materials may be attached with dust, and packaging materials may generate debris, etc., all of which will affect the cleanliness after entering the clean area.
- Moreover, if some materials are polluted during transportation and storage, they will also bring pollutants into the clean factory.
2. Volatilization and Chemical Reactions of Materials
- Some materials may volatilize or undergo chemical reactions in the clean factory, generating harmful gases or particulate matter, thereby affecting the cleanliness. For example, some organic solvents will volatilize during use. If the ventilation system does not handle it in a timely manner, the air quality in the clean area will decline.
- In addition, some materials may undergo chemical reactions with each other, generating new pollutants, which will also have an adverse impact on the cleanliness.
IV. Environmental Factors
1. Poor Sealing of Clean Factory Structure
- If there are gaps or poor sealing in the walls, ceilings, floors, etc. of the clean factory, dust and air from the outside may seep into the clean area, affecting the cleanliness. Especially in some old clean factories, long - term use may lead to deformation and damage of the building structure, resulting in a decrease in sealing performance.
- For example, if the sealing strips of doors and windows in the clean factory age, air will enter through the gaps.
2. Improper Temperature and Humidity Control
- The temperature and humidity in the clean factory also have a certain impact on the cleanliness. If the temperature is too high or too low, or the humidity is too high or too low, dust particles may aggregate or fly, thus affecting the air cleanliness.
- For example, in a relatively humid environment, some tiny dust particles are prone to absorb moisture and become larger, with a slower settling speed and are more likely to be suspended in the air. When the temperature is too high, some materials may release more volatile substances, affecting air quality.
3. External Environmental Pollution
- If there are pollution sources in the surrounding environment of the clean factory, such as factory exhaust emissions and road dust, it may also affect the cleanliness of the clean factory. Even if the purification system inside the clean factory operates normally, external pollutants entering the clean area through the ventilation system or other means will lead to non - compliance of cleanliness.
- For example, if there is a construction site near the clean factory, dust may flow into the clean factory with the air.
V. Construction and Maintenance Factors
1. Construction Quality Problems
- During the construction process of the clean factory, if the construction quality is not up to standard, such as insufficient ground flatness, uneven wall coatings, and non - standard pipe installation, problems such as dust accumulation and poor air flow may occur, thus affecting the cleanliness.
- For example, if the ground has bumps or depressions, it is easy to accumulate dust and is difficult to clean, becoming a pollution source affecting the cleanliness.
2. Inadequate Maintenance Management
- After the clean factory is completed, subsequent maintenance management is very important. If the purification equipment is not regularly maintained, filters are not replaced, and ventilation ducts are not cleaned, the performance of the equipment will gradually decline, and the cleanliness cannot be maintained.
- At the same time, if the sanitation and cleaning work in the clean factory is not emphasized, such as not cleaning up the ground garbage in a timely manner and not wiping the equipment surface regularly, the cleanliness will also be affected.
Having understood these reasons for non - compliance of cleanliness in clean factories, we can take targeted measures for improvement and prevention.
