Comparison of electrolytic coloring methods and functions of aluminum and aluminum alloys
With the increasing use of aluminum and aluminum alloys, and the increasing demand for its decoration and functionality, various requirements for electrolytic coloring have been proposed in production.The color film obtained by the electrolytic coloring skills of aluminum and aluminum alloys has excellent abrasion resistance, light resistance, heat resistance and corrosion resistance of various chemical media. It is more used for the decoration and protection of various profiles. .Because of the development and application of solar energy, the diversification of daily commodities, and the popularization of skilled arts, the color and luster of aluminum and aluminum alloy finished products have set very clear goals and requirements.For example, if the curtain wall of a large building in the city is silver-white and the reflection is too strong, it will affect the senses of pedestrians and affect air traffic, and it will briefly form optical pollution. Therefore, it is expected to use darker and softer bronze or other colors.
Advantages of LED lampshade tube
1. The original T8 tube bracket was designed to protect the fragile T8 tube, but the current LED light tube has sufficient strength and no longer needs protection.So the bracket can be removed!2. The original two ends of the pins are used to match the special connection of the T8 tube, and the connection of the led tube is no longer necessary.And that connection is a challenge to waterproofing and security.Therefore, the design of the lamp tube no longer needs pins, and a more simple and reliable connection method can be adopted!
The heating and cooling speed of aluminum profiles should not be too fast
The heating speed of aluminum profiles is based on the principle that the ingot does not cause cracking and excessive deformation.Holding time The holding time should ensure a certain annealing temperature to dissolve the non-equilibrium phase and eliminate intra-grain segregation, but it should be based on alloy characteristics, ingot size, degree of segregation, shape and size and distribution of the second phase, heating equipment and temperature , Determine the length of the holding time.Practice has proved that the rate of the homogenization process increases with time, but gradually decreases from large.Therefore, it is not appropriate to extend the holding time excessively, which will increase the burning and energy consumption of the metal and reduce the productivity.After the cooling rate is equalized, the ingot can be cooled with the furnace, or it can be air-cooled.
How to maintain the surface of aluminum profiles
Aluminum profiles manufacturers can not only greatly reduce the weight of the building and save materials, but also reduce the workload of component transportation and installation, and speed up construction.Aluminum and aluminum alloys have beautiful colors, strong corrosion resistance, high reflectivity to light and heat, and good sound absorption properties. Various colors can be obtained through chemical and electrochemical methods.Therefore, aluminum is widely used in roofs, walls, doors and windows, skeletons, interior and exterior decorative panels, ceilings, ceilings, railings, handrails, interior furniture, shop containers, and formwork for construction in various buildings.
