Knowledge|Why do aluminum profiles turn black? Aluminum profile is a non-ferrous metal profile that is extruded by die and oxidized and coated. The aluminum profile is treated by anodizing and other treatments, and there is an oxide film on the surface, which makes the profile have the characteristics of corrosion resistance and corrosion resistance. Recently, some users found that the aluminum profiles turned black during the use of aluminum profiles. Let us popularize the reasons for the blackening of aluminum profiles. 1. The aluminum profile process is not up to standard: the aluminum profile is extruded from an aluminum rod and then oxidized and coated. The selection of raw materials for aluminum rods, improper cleaning or pressure inspection of aluminum profiles in the production process, and uneven coating during the oxidation process of aluminum profiles will all lead to blackening and mildewing of aluminum profiles. We use 6063-T5 aluminum rods, which are not doped with waste, and undergo a strict extrusion production process. Ensure the quality of aluminum profiles from the source. 2. Improper storage management: Although aluminum profiles are waterproof, corrosion-resistant and corrosion-resistant, if they are in a humid environment for a long time, they will be in direct contact with uneven ground. Then it will also cause the aluminum profile to wear and tear, and the oxide film will be damaged, which will cause the aluminum profile to become moldy and black. In view of this situation, aluminum profiles can be stored in a dry and ventilated environment, and direct contact with the ground should be avoided. 3. Unreasonable cleaning management: The surface of the aluminum profile is anodized and generally does not need to be cleaned. If there is dust, just wipe it gently with a soft cloth. If a corrosive cleaning agent is used, the surface of the aluminum profile will be corroded and oxidized, resulting in mildew and blackening of the surface of the profile. With the development of technology and the improvement of the level of social development, the market demand for aluminum profiles is also increasing, and various manufacturers have sprung up like bamboo shoots after a rain. If you choose a bad cooperative manufacturer, the loss will be heavy, not to mention the possibility of introducing inferior products and causing major safety accidents.

It is industrial aluminum profile that can be seen everywhere in our lives. Its application range is gradually expanding and has been widely used in our lives. Many people do not understand the application range of industrial aluminum profile. Now I will explain the application range of industrial aluminum profile. 1. Industrial aluminum profile is a new type of product. In the field of industrial production and manufacturing, it is manifested in automated machinery and equipment, assembly line conveyor belts, hoists, dispensers, testing equipment, shelves, electronic machinery industries and clean rooms. 2. The production line is a large-scale conveying equipment, and the aluminum profile can be well planned for the area and play a protective role, which is what we often call aluminum profile fence, aluminum profile protective cover, etc. 3. The storage department in the factory is also indispensable, such as material racks, mobile trolleys, stair treads, etc. are also made of industrial aluminum profiles. 4. Due to the advantages of aluminum profile, such as light weight and corrosion resistance, it is also very suitable for medical treatment, such as stretcher frame, medical equipment, medical bed, etc. 5. Aluminum profile is lighter in weight, strong in load capacity, and special profile structure is convenient for the installation and connection of electrical equipment, so it also has its own place in the field of automobile manufacturing. The five major areas summarize the application range of industrial aluminum profiles, the most extensive of which is undoubtedly the aluminum profile frame, which has a variety of assembly forms, and is generally designed according to customer requirements.

Thermal-break aluminum doors and windows are the fifth generation of new thermal insulation and energy-saving doors and windows after wooden windows, iron windows, plastic steel windows, and ordinary color aluminum doors and windows on the market, and they are the highest-level aluminum doors and windows. The surface of broken bridge aluminum alloy doors and windows can be painted in various colors according to the needs of customers. The composition structure of the thermal-break series aluminum alloy doors and windows combines the environmental protection of wooden windows, the firmness and safety of iron and steel windows, and the common characteristics of plastic-steel doors and windows for heat preservation and energy saving. Its structure is more complicated than ordinary aluminum doors and windows, and the cost is higher. Ordinary aluminum does not have heat insulation strips, does not keep heat and does not save energy. It just sprays on the surface. The section wall thickness of the aluminum alloy doors and windows of the thermal-break strictly follows the national standards. The wall thickness requirements must be between 1.4 and 2.0mm, because the thickness of the wall is related to the assembly technology and the solid safety of the doors and windows. The wall thickness of ordinary aluminum doors and windows should generally be below 1.4mm. Thermal-break series aluminum alloy doors and windows are assembled with special corner codes of more than 3mm, and corner glue should be injected into the corners for sealing. However, ordinary doors and windows are only connected by rivets or screws, and their firmness and safety are poor, but the cost is low. And the assembled thermal-break series aluminum alloy doors and windows will not have any problem for adults standing on and walking around. The technical requirements for the assembly of a complete set of equipment and the manual on-site operation are very different. The special thermal-break series aluminum profile is much more advanced than the ordinary aluminum profile, so it is not comparable.

Anhui Shengxin Aluminium Group Co.,Ltd is a professional manufacturer of world advanced middle and high grade door and window sections in buildings, curtain wall sections, decorative sections and industrial sections. The factory covers an area of 146,000 square meters. There are 980 employees at present, including 90 engineering and technical personnel with education higher than college. There are more than 30 modern aluminum alloy section production lines, including smelting casting, extruding, ionization, powder coating, electrophoresis painting, chemical polishing, wood grain transfer printing and thermal insulation bridge cut off machines. Our annual production capability is 30,000 metric tons of aluminum extruding sections. For tens of years manufacture and management experience,we have got ISO9001:2000 and ISO14001 certificates. Our advantage: As our factory located in China inland areas, the land and labor cost is much lower than coastal areas, such as Zhejiang,Guangdong,Shanghai,Jiangsu,etc. So the product price in the same quality is much more competitive. Compare to some other inland big companys, they are all located too far from port,the delivery cost for them are very high,but we are only 200 kilometres away from Shanghai port. Compare to the factories in the same areas with us, they are too small,their management are behindhand,they cannot guarantee your goods quality.
