[China Glass Network] Due to the relatively large amount of salt and alkali contained in the wind and rain in coastal areas, some areas have used sea sand and sand conditions that have not been desalinated and used in national standards. The corrosion of aluminum alloy doors and windows is more serious. Special attention. In addition to the procedures described above, the following procedures should be followed: RTS short,High Quality RTS short,RTS short Details, CN Shaoxing Qili Import And Export Co.,Ltd , https://www.qili-apparel.com
1. The aluminum doors and windows that are transported to the site shall be placed in a well-ventilated, dry bath and clean warehouse.
2. The height of the sleeper's surface from the ground should be >=100mm, and the stack should not exceed 15 molds (fans). The soft material should be applied between each mold (fan) to prevent crushing and aluminum alloy and hardware. The mutual friction destroys the protective film on the surface of the profile.
3, the door and window openings must have a drip line, should be tested before installation. Because the rainwater flowing through the wall made of sea sand is very corrosive, it must be prevented.
4, the installation of iron pieces should be card type, to minimize the damage to the aluminum alloy protective layer processing.
5. The joint of the aluminum alloy profile is sealed with a neutral glue to prevent rainwater from entering the inner cavity without the protective layer. As a rule of thumb, corrosion usually begins with the inner cavity without a protective layer.
6. After the interior and exterior decoration is completed. Remove the protective tape and clean the doors and windows. Do not clean the doors and windows with corrosive liquids or hard objects to avoid damage to the surface paint film.
7, important tips:
1) Aluminum is a lively metal. The damage of the protective layer is not anti-corrosive. It is easy to occur. The bat should be taken to protect the surface of the profile.
2) Water is the source of corrosion, and it should be prevented from entering the inner cavity of aluminum alloy profiles without anti-corrosion ability.
