Cleanroom-grade corrugated steel sheets are composite panels specifically designed for clean environments. They feature a smooth surface, fire resistance, and antibacterial properties, and are commonly used in high-environment environments such as electronics factories and operating rooms.
1. Surface Cleaning: Use a specialized cleaning agent or neutral detergent to remove dust, oil, and other contaminants from the surface of the corrugated steel sheet. The concentration of the cleaning agent and the cleaning time need to be adjusted according to the degree of contamination. Generally, a cleaning agent concentration of 5%-10% and a cleaning time of 10-15 minutes are recommended.
2. Rust Removal: For corrugated steel sheets that have already rusted, use a rust remover or mechanical methods (such as sandpaper polishing) to remove rust. When using mechanical rust removal, it is recommended to control the rotation speed at 1200-1500 rpm to avoid excessive surface abrasion.
3. Oxide Removal: Use chemical or physical methods to remove oxides from the surface of the corrugated steel sheet. Commonly used chemical methods include acid pickling or alkaline washing. Strict control of treatment time and concentration is necessary to avoid damaging the corrugated steel sheet substrate.
4. Oxide Removal: Use chemical or physical methods to remove oxides from the surface of the corrugated steel sheet. Common chemical methods include acid pickling or alkaline washing. Treatment time and concentration must be strictly controlled to avoid damaging the corrugated steel sheet substrate. Surface repair: For color steel plates with scratches or damage, local repairs are required, such as touch-up painting or applying a protective layer, to restore their protective performance.
