Clean room cleaning supplies play a crucial role in maintaining the controlled environment required for various industries, especially in semiconductor manufacturing.
Types of Clean Room Cleaning Supplies:
- Wipes, Sponges, Mops, and Towels:
- Materials Used: Paper, cotton, polyester, nylon, cellulose polyester blend, microfiber, and molded plastics.
- Selection Criteria: Chosen based on their ability to meet the required ISO classification without generating particles.
- Disinfectants, Wiping Alcohol, and Acetone:
- Used for cleaning and disinfecting surfaces in clean rooms.
- Static Clean Space Cleaning Supplies:
- Tacky Mats, Tacky Rollers, and Footwear Cleaners:
- Used to control and minimize the transfer of particles through footwear and rolling equipment.
- Tacky Mats, Tacky Rollers, and Footwear Cleaners:
- Equipment:
- Auto clave (Sterilizer), Steam Cleaners, and Vacuum Cleaners:
- Essential tools for maintaining cleanliness in a clean room environment.
- Auto clave (Sterilizer), Steam Cleaners, and Vacuum Cleaners:
Clean Room Technology:
- Inventor: Willis Whitfield is credited with inventing the modern clean room in 1960.
- Technology: Based on a constant flow of filtered air, using HEPA filters to remove airborne particles.
- Evolution: Continuous refinement and improvement over the years.
Clean Room Classifications:
- ISO Classification: Specifies the maximum number of particles per cubic meter for different particle sizes.
- Ranges from ISO 1 to ISO 9: ISO 1 being the cleanest with the lowest particle count.
Material Selection for Clean Room Cleaning Supplies:
- Organic to Synthetic Materials:
- Selection depends on the ISO classification required.
- Ranges from paper and cotton (generating more particulates) to microfiber and molded plastics (suitable for the most stringent conditions).
Absorbency:
- Critical Attribute: Ability to absorb water and fluids.
- Materials and Absorbency:
- Least absorbent: Paper and cotton.
- Mid-range: Nylon, polyester, and polyester blends.
- Most absorbent: Microfibers and molded plastics.
Considerations for Clean Room Cleaning Supplies:
- Cleanliness, Longevity, and Environment:
- Cleanliness (lack of particulate generation) is crucial.
- Longevity and suitability for the intended environment are important factors.
Clean room cleaning supplies are tailored to meet the specific requirements of clean room classifications. The choice of materials, absorbency, and cleanliness features depends on the tasks performed and the level of cleanliness needed. Regular reference to the ISO classifications ensures that the right supplies are used for the specific clean room environment.
