How to distinguish the true and false of aluminum profile
When you make the Fenglv aluminum material before installation, be sure to carefully observe the surface of profile, the existence of marks. If you were not allowed to see on the surface, you have the right to request processing and installation personnel to do a good job in the windows and doors, open a door or window frame, see section profiles in the middle of the inner wall, do surface spray treatment, which can not be sprayed to the section, so you see the color profile is not covered by the powder, so it is easy to if there is differential profile marks. There is no any authentic Feng streak lines. We recommend you to see when the processing requirements of installation personnel open a door or window frame observation you specify, in the absence of color powder surface observation, differential can easily pull!The main difference between true and false identification is the difference between Feng materials, the relevant logo really materials have Feng Feng, and point code; there is a difference in structure, but the average person is not easy to identify, is false is imitation Feng al Feng material, so it is not 100% imitation, so the fixed window is different, the line is not the same, this point without a careful comparison is not too much attention; and actually is not the same aluminum surface treatment, surface color really Feng wavy uniform, did not occur, but not because it is relatively poor in the local aluminum equipment under the electrostatic spraying, it is not possible to achieve the level of surface treatment of aluminum.Now due to the requirements of the color type is more, so the regular manufacturers have no choice except white, green, there is no aluminum Nanjing stock, so the manufacturer had to really change color when Feng, this situation is best to distinguish between true and false identification to the Al Feng Nanjing office.
1. Light weight 2. 3 and after the incision is white within 4 hard, very fine very hard
Al Feng brand aluminum precision identification method is to do chemical detection. But in the absence of our conditions, we can only use "observation" to distinguish. What is "observation method", that is, we make a different perspective on the surface of aluminum. Aluminum door and window section is made of aluminum rod by die extrusion and the like, fake phoenix aluminum using bauxite as raw material, so the material contains a lot of impurities, extrusion is easy to mold galling, the surface profile produced is not smooth, there are many marks, and profiles of scrap produced. Can not be reached in a variety of physical effects on strength and hardness.The surface treatment of fake profiles for powder coating (common color: green, white, grey), said simply in this way, the profile above is squeezed out of the powder coverage, this method has great advantage on fake garbage can be squeezed out of aluminum profiles, profiles on the marks effectively cover. But because of fraud for more cost savings, they use inferior adhesion powder, short life, easy to fall off, and covered in the profile of the powder also small and thin, and extruded profile marks are too deep, even if there is a cover up the layer of powder, as long as viewed from different angles and shapes position still, it is easy to see these ugly marks.
