After the industrial aluminum profile is oxidized, the appearance is very beautiful, and it is resistant to dirt. Once it is coated with oil, it can easily be washed away. When assembled into a product, different specifications of profiles are used according to different load-bearing materials, and matching aluminum profile accessories are used, without welding. It is more environmentally friendly, and the installation and disassembly are light and easy to carry, and it is extremely convenient to move. According to the field of application of industrial aluminum, industrial aluminum profile profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. The titanium and gold plating process for aluminum profiles is a coating technique. It basically adds pre-plating and electroplating steps in the general titanium plating process. The pre-plating process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment; The composition of the plating solution in the electroplating process includes nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good results. The film hardness is HV≈1500, and it is 150 times more wear-resistant than 22K gold plating under the same premise. It can be processed into a variety of bright series of aluminum products such as gold, color, and black in various conditions. According to the field of application of industrial aluminum, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. The aluminum profile titanium plating process includes the process steps of material selection, polishing, chemical degreasing, water purification, activation, and vacuum titanium plating. The feature is that it also includes: A. Electroplating process. The plating solution in the process contains nickel sulfate, Nickel chloride, boric acid, sodium lauryl sulfate, saccharin, brightener, process premise: current 3-4A/dm cathode movement, 5-7A/dm air stirring, bath temperature 50-60℃, PH value 3. 9-4.2, 15 minutes for electroplating. According to the field of application of industrial aluminum, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. B. Pre-plating process. This process is to place the activated titanium-gold-aluminum profile washed by purified water in a liquid composed of salt, hydrochloric acid and water for chemical treatment. The treatment temperature is normal temperature, and the treatment time to liquid produces intense chemistry. So far
