How to use A4 magnetic esd anti-static hard holder
A4 magnetic anti-static hard rubber sleeve is mainly used to protect documents in electrostatic sensitive environments such as dust-free workshops and electronic manufacturing, and uses magnetism to achieve convenient display or fixation. The following are specific usage methods and precautions:
1. Usage steps
File loading
Put the A4 document into the rubber sleeve, and pay attention to the opening direction (usually long-side or short-side opening styles are provided). Make sure the document is flat and wrinkle-free to avoid affecting the anti-static performance due to folding.
Magnetic fixation and display
Adsorption on metal surfaces: Using the magnetic strip embedded in the edge of the rubber sleeve, it can be directly adsorbed on metal shelves, equipment or magnetic whiteboards.
Hanging use: If the rubber sleeve has holes (such as perforated styles), it can be fixed on the workstation or shelf with a hook.
Static protection operation
Wear anti-static gloves or wristbands during operation to prevent human static electricity from being transmitted to the document through the rubber sleeve.
Use in a dust-free environment to reduce static electricity accumulation caused by dust friction.
️ 2. Key considerations
Material and performance
The rubber sleeve base material is an anti-static graphene/PVC composite material, and the surface resistance must be maintained in the range of 10⁵–10⁹Ω (ohms) to ensure the electrostatic shielding effect.
Avoid friction with sharp objects to prevent surface scratches that may cause the anti-static coating to fail.
Environmental requirements
The storage environment needs to be dry and ventilated, and the temperature must be above 5°C to avoid high temperature and high humidity that may cause material aging.
Wipe the surface with an anti-static cleaner regularly to maintain anti-static performance.
Compatibility
The rubber sleeve is available in a variety of sizes such as A3/A4/A5, and the matching model must be selected according to the document specifications.
The magnetic strip strength is divided into ordinary/strong magnetic specifications. It is recommended to use a strong magnetic model for heavier documents to prevent slipping.
3. Typical application scenarios
Workshop document management: Hanging equipment operation guides and process flow cards on the production line, and the magnetic suction design facilitates quick replacement.
Warehouse identification: Magnetic adsorption on metal shelves to display inventory labels or safety instructions.
Electrostatic sensitive area: Protect circuit diagrams, chip specifications and other documents from electrostatic damage.
Tips: If the adsorption force decreases or the surface resistance is abnormal after long-term use, it is recommended to replace the rubber sleeve to ensure the protection effect.
