What are the maintenance requirements for aluminum alloy shutters in long-term use?

The following are the long-term maintenance requirements for aluminum accordion shutters, especially considering their functional characteristics such as pressure bearing capacity, water resistance, air supply pressure and sound insulation performance.

1. Regular cleaning
Remove dust and stains: Since dust and stains easily accumulate on the surface of aluminum alloy blinds, you should regularly use a soft cloth or vacuum cleaner to clean the window surface, especially the gaps between the blades.
Wet cloth wiping: Use a wet cloth to wipe the blinds every month. It is recommended to use warm water and neutral detergent. Do not use strong acid or strong alkaline detergents to prevent damage to the coating or oxide film.
Clean the gaps: Regularly clean the gaps between the blades. You can use special blinds cleaning tools, or gently use a vacuum cleaner to suck away dust to avoid dust accumulation affecting the opening and closing of the blinds.

2. Check and maintain waterproof performance
Check the sealing performance: The waterproof performance of aluminum alloy blinds is greater than 50KG/M², ensuring that the sealing performance of the blinds blocks water. Regularly check the sealing strips and connecting parts of the blinds. If they are worn or damaged, replace them in time to maintain their waterproofness.
Remove sewage accumulation: Especially in the area where the window frame contacts the wall, water or mud may accumulate, which should be cleaned regularly to prevent water accumulation from affecting the function and appearance of the blinds.

3. Check the moving parts and pressure bearing capacity
Check the adjustment rod and moving parts: The pressure bearing capacity of aluminum alloy blinds can reach 175MPH, which means it can withstand strong wind pressure. Regularly check the moving parts such as adjustment rods, hinges, and fixtures to ensure that they operate smoothly without jamming or loosening.
Check the brackets and mounting components: For blinds that are subject to strong wind pressure, the stability of the mounting brackets should be checked regularly to ensure that the fixing components are not loose. Especially after stormy weather, it is necessary to check again whether the blinds are firmly fixed to avoid falling off or damage.
Lubricate the moving parts: If the adjustment rod or hinge of the blinds is noisy or not smooth, you can use an appropriate lubricant (such as silicone oil) to lubricate them.

4. Prevent oxidation and corrosion
Check the coating and oxide film: Aluminum alloy material itself has strong corrosion resistance, but it may still oxidize or corrode if exposed to humid or high-salt environment for a long time. Regularly check whether the anodized film or coating on the surface of the blinds is intact. If the coating is found to be peeling or corrosion marks are found, it should be repaired or re-coated in time to ensure its anti-corrosion effect.
Avoid contact with corrosive substances: Avoid long-term contact of aluminum alloy blinds with strong acids, strong alkalis or substances with high salt content, especially buildings in coastal areas or industrial areas, and pay special attention to the impact of the surrounding environment on the blinds.

5. Check the sound insulation performance
Check the sealing and sound insulation effect: The sound insulation capacity of aluminum alloy blinds is more than 30dB, ensuring that the blinds can effectively reduce external noise after installation. Regularly check the sealing strips and the closing state of the blades of the blinds to ensure their airtightness. If the sound insulation effect is found to be reduced, it may be due to aging of the sealing strips or damage of the blades, which need to be replaced in time.
Check the contact surface of the window frame and the blades: The sound insulation effect is related to the sealing and contact surface tightness of the blinds. If there is a gap between the shutter blades and the window frame, or the sealing strip is aged, the sound insulation effect will be affected.

6. Avoid bad weather
Protection in high wind weather: Although aluminum alloy shutters have high pressure bearing capacity, they may still be affected under wind conditions. After strong winds or heavy rain, check whether the shutters are damaged by external forces. If used in weather such as typhoons, the shutter angle can be adjusted or completely closed to reduce external damage.
Prevent long-term exposure to sunlight: Although aluminum alloy materials have good UV resistance, long-term strong sunlight exposure may still cause certain damage to the surface coating and materials. Regularly check the surface of the window frame for fading, cracking, etc., and maintain or repaint it in time.

7. Maintain the fixings
Check the mounting screws and brackets: The fixing brackets and screws of aluminum alloy shutters may loosen during long-term use. Check the mounting screws and brackets regularly to ensure that they are firmly fixed. For high windows that cannot be reached, it is recommended to check them once a year to ensure safety.
Check the firmness of the blades: Make sure the blades of the blinds have not become loose, deformed, or damaged during normal use.
