Need to know about the later maintenance of Al-Mg-Mn-Al sheet on roof.

When installing the Al-Mg-Mn aluminum sheet on the roof, if there are slight scratches on the surface, don't worry, the Al-Mg-Mn aluminum sheet will repair itself and rebuild a new passivation layer. If there are deep or large scratches, you should consider replacing them.

Protective film: In order to prevent scratches during transportation and installation, the manufacturer of Al-Mg-Mn-Al plate coated a protective film on the surface of the product. Remove the protective film as soon as possible after installation. After installation, it is recommended to remove the protective film within 6 months.

Oil level and dust: If there is a small amount of oil and dust accumulated on the surface of Al-Mg-Mn roof panel during installation, it can be wiped gently with a clean dry cloth, and it is not allowed to rub hard or use cleaning products. Rain can naturally wash away dust.

Fingerprint removal: When Al-Mg-Mn plate is applied to curtain wall, attention must be paid to the fingerprint problem. A better removal method is to use mineral oil. Wearing cotton gloves during installation can prevent fingerprints.

Roll material should be kept in its original state. If you need to overlap due to lack of space, you can follow the following principles:

1. When the coil is placed according to the horizontal axis, it shall be stored separately and shall not be stacked.

2. If the rollers are installed longitudinally, wooden frames can be stacked. In order to ensure stability and safety, there are many Al-Mg-Mn aluminum plates that can be folded into five layers.

3. The storage time of plates and coils should be as short as possible, especially in the construction site.

To ensure product quality, please strictly follow the following storage suggestions:

1. Aluminum, magnesium and manganese plates or rolls must be stored in a ventilated, dry, cool and constant temperature place, and shielding measures should be taken to prevent condensation.

2. The board and coil must be separated from the ground with a wooden frame to form enough air circulation space.

3. In order to ensure that the material is not deformed, all plates must be put on the shelf.

4. When transporting aluminum, magnesium, manganese and aluminum plates, they can be arranged horizontally or vertically according to customer requirements.

Control principle of design and construction quality of aluminum magnesium manganese aluminum plate

A, according to the requirements of design and specification construction, governance aluminum magnesium manganese aluminum roof leakage quality common fault.

Leakage of Al-Mg-Mn roof is a common quality problem in roof engineering, which mainly means that rainwater enters the insulation layer through the waterproof layer, which greatly increases the moisture content in the insulation layer and reduces the insulation results. The main reasons for roof leakage are: first, the construction time and conditions of roof insulation layer and waterproof layer do not meet the requirements, blindly rushing for progress regardless of whether the construction climate conditions are suitable for construction, such as rainy day construction, which increases the moisture content in insulation layer and causes the waterproof layer to bulge and damage. And when the temperature is too low, the waterproof coiled material is laid, which seriously affects the waterproof quality; Second, the surface of the roof waterproof base is uneven, unclean and not dry, which is also the reason for the hollowing and leakage of the waterproof layer; Third, the paving direction of roofing waterproofing membrane, the lap method and lap width of the membrane do not meet the requirements of construction specifications, which leads to the leakage of roofing waterproofing membrane. Therefore, to reduce the moisture content in the insulation layer and prevent the leakage of aluminum-magnesium-manganese-aluminum roof, the construction must be organized according to the design and specification requirements.

Second, adopt ecological planting roof.

Planting the roof is to cover the waterproof layer or rigid protective layer of the building with planting media, and plant plants (flowers and grass) to make the roof form vegetation and become a hanging garden, which not only plays a good role in heat insulation, but also is green and environmentally friendly.

Planting roofs are divided into two types: covered soil planting roofs and soilless planting roofs. The slope of planting roof should not be greater than 3%. Waterproof materials with corrosion resistance, mildew resistance, plant root puncture prevention and good water resistance should be used for the waterproof layer of planting roof, and a rigid protective layer should be set on the upper part of the waterproof layer of coiled material. A filter layer should be set on the drainage layer. The planting medium for planting the roof covered with soil should meet the design requirements and meet the needs of planting plants on the roof. When there is no requirement in the design, the thickness of planting soil should not be greater than 800mm to prevent the roof load from being too large; Soilless planting roof uses water residue and vermiculite instead of soil as planting layer, which can reduce roof load and improve roof insulation results.

In a word, it is an important link to improve the energy-saving level of buildings, an important technical measure to realize the energy-saving achievements of building envelope, and it is of great significance to building energy conservation to improve the thermal insulation performance of aluminum-magnesium-manganese aluminum roof and strengthen the thermal insulation achievements.
