How To Judge The Advantages And Disadvantages Of Light Box Aluminum Profiles?
Dec 21, 2018
Aluminum profile products have the advantages of high strength, light weight, corrosion resistance, good decoration, long service life and rich colors. Generally, a good product has no surface loss and no discoloration for 20 years. Because these advantages are favored by many manufacturers. So what do you need to pay attention to in the light box aluminum profile? How to judge the quality of aluminum profiles?
Precautions Pay attention to the following points when purchasing and using profile products:
1. Check the product factory certificate, pay attention to the date of manufacture, specifications, technical conditions, company name and production license number.
2. Carefully check the surface condition of the product. The product should be bright and bright, and the surface should not have obvious scratches, bubbles and other defects.
3. Be sure to pay attention to the wall thickness of the product. The product thickness of the door and window material should not be less than 1.0mm.
4. Pay attention to the thickness of the surface coating of the product. The film thickness of the anodized product is not less than 10μm, the film thickness of the electrophoretic paint product is not less than 17μm, the thickness of the powder coating is not more than 40-120μm, and the fluorocarbon paint is sprayed. The product should be above two coats and should not be less than 30μm.
5. It is best for users in coastal areas to choose electrophoretic paint profiles, powder spray profiles or fluorocarbon spray profiles with good corrosion resistance.
6. Do not use other hard objects such as brushes as a cleaning tool for routine maintenance. Choose soft cotton yarn and cotton cloth.
7. Use water, detergent and soap when washing, but not other organic substances.
Inferior feature
Squeeze the defect. During the extrusion process of aluminum profiles, whether the extrusion equipment is complete, whether the extrusion process is mature and whether the operation is improper, defects such as bubbles, inclusions, layering, chromatic aberration, distortion, etc., affect the quality of the aluminum profile.
The oxide film is thin.
According to experts' estimates, for every 1 um reduction in oxide film thickness, the cost per ton of profile can be reduced by more than 150 yuan. The chemical composition is unqualified. The aluminum profile with a large amount of miscellaneous aluminum and scrap aluminum can greatly reduce the cost, but it will lead to the unqualified chemical composition of the aluminum profile of the building, which seriously endangers the safety of the project.
Reduce the wall thickness of the profile.
Inferior aluminum profiles greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of the profiles is also greatly reduced.
