I. The Cleanroom Consumables?
1. Definition: Cleanroom consumables are disposable or reusable consumables used in cleanroom environments to prevent the release of particles, microorganisms, or chemical contaminants into the air by personnel, tools, or materials, thereby maintaining ISO-specified cleanliness levels.
2. Core Features: Low particle emission, zero static electricity, chemical resistance, and the ability to maintain integrity under highly filtered airflow.
3. Industry Value: In high-end manufacturing sectors such as semiconductors, pharmaceuticals, biotechnology, and aerospace, cleanroom consumables are critical for ensuring product quality and reducing defect rates.
II. What are the common categories of cleanroom consumables?
1. Cleanroom Apparel
Anti-static coveralls, disposable dust masks, gloves, shoe covers, hats, etc. are all made of low-particle, low-ion materials and meet ISO 4-ISO 7 protection requirements. 2. Cleaning and Disinfection Supplies
Dust-free wipes, pre-moistened wipes, sterile cleaning cloths, alcohol/hydroxide disinfectants, etc., for daily dust removal and disinfection of workbenches, equipment surfaces, and hands.
3. Packaging and Handling Supplies
Anti-static packaging bags, dust-free trays, sealed containers, sticky mats, etc., ensure the cleanliness and integrity of finished or semi-finished products during handling and storage.
4. Testing and Monitoring Tools
Specialized calibration consumables for high-end testing equipment such as particle counters, ion counters, liquid particle counters, and infrared spectrometers, enabling real-time monitoring of cleanroom environmental indicators.
5. Company Case Study: Suzhou Jujie Electronics, a leading manufacturer of cleanroom consumables in China, boasts a 33,000 m² production facility equipped with 48 automated weaving, washing, and forming production lines, as well as high-end equipment such as laser cutting and ultrasonic cutting imported from Japan, Germany, and the United States. This has increased its annual production capacity tenfold, allowing it to provide a full range of consumables and testing instruments for ISO5-ISO7 cleanrooms.
III. How to Choose Gloves and Protective Clothing Suitable for Different Cleanroom Classes (ISO5, ISO7, etc.)?
1. Key Points for Glove Selection
Material and Particle Emission: ISO5 requires gloves to emit extremely low particle emissions in their natural state. Natural rubber latex (NRL) or low-particle polyurethane is recommended, meeting the rigorous testing requirements of GB/T1.1-2020 and ISO20437:2017.
Non-Volatile Residue (NVR): The surface of the gloves must pass the Total Non-Volatile Residue (Total NVR) test to ensure that no chemicals such as silicone, amines, or DOP are released into the cleanroom air.
Size and Comfort: In high-cleanroom environments, workers' hands frequently move, so gloves should provide sufficient elasticity and a snug fit to prevent particle generation due to stretching.
Disposable vs. Reusable: ISO5 environments prefer disposable gloves to avoid secondary contamination during cleaning. ISO7 environments can choose reusable, low-particle gloves to reduce costs and meet environmental requirements. 2. Key Points for Protective Clothing Selection
Fabric and Antistatic Properties: ISO5 requires low-ion, antistatic non-woven fabrics or polyester/polyamide composites to prevent electrostatic adsorption of particles. ISO7 can use standard antistatic polyester fabrics to meet basic protection requirements.
Structural Integrity: Seams, zippers, cuffs, and other areas of protective clothing must be heat-sealed or adhesively bonded using a dust-free, burr-free process to prevent particle shedding.
Number of Layers and Protection Level: ISO5 typically uses a fully enclosed disposable coverall (including a hood, mask, and shoe covers) with at least two layers. ISO7 can use a semi-enclosed coverall with dust-proof shoe covers and gloves.
Cleaning and Replacement Cycle: Protective clothing in ISO5 environments must be rigorously rinsed with RO-DI water before and after each entry and stored in dust-free packaging. ISO7 can be washed and air-dried conventionally to ensure the absence of residual particles. 3. Comprehensive Recommendations for Balancing Comfort and Safety
Matching the Cleanroom Air Pattern: When using a unidirectional airflow (UDAF) or non-unidirectional airflow (non-UDAF) system, the protective clothing should be designed to align with the airflow direction to prevent the clothing from swaying in the airflow and causing particle resuspension.
Supporting Accessories: Use accessories such as sticky mats, cleanroom gloves, and disposable masks to form a complete protective chain, further reducing the risk of personnel contamination in the cleanroom.
Supplier Qualifications: Prefer suppliers that are ISO14644-5 and NEBB certified, such as Suzhou Jujie Electronics, to ensure their products meet international cleanroom standards and provide complete test reports.
