Carbon fiber is used as a structural material or functional material because of its unique super performance, in order to make full use of the characteristics of carbon fiber. The surface treatment of carbon fiber metal seems to be important. The ring-like solution is for the structure and characteristics of carbon fiber surface. The harm is not the same. For the different application requirements of carbon fiber, the different surface process should also be used. Let's introduce to everyone the metal surface treatment methods and advantages of carbon fiber materials.
From the current stage, the more common keys used are the following three methods:
1. Smelly air oxidation method. This type of craftsmanship is more commonly used. Because the processing technology is relatively simple, the engineering cost of machinery and equipment is also relatively low, and the solution time is relatively short, but the solution is effective. It is a good way to continue to carry out metal surface treatment on carbon fiber at this stage. The advantage is the air oxidation reaction speed, the solution time is shorter, which can be in line with the carbon fiber production line, the air oxidation is alleviated, the reaction is symmetrical, and it is easy to control, which promotes the virtual beam shear strength to be greatly improved. This kind of processing technology is suitable for the production and manufacture of low-cost civilian carbon fiber.
2. Anodizing, electrolysis, and air oxidation. It is also called the photoelectric catalytic air oxidation method. The formula is to anodic carbon fiber. The electrolyte solution can only use inorganic substances or citric acid and salt. Alkali is also acceptable. The type of electrolyte solution is different. The air oxidation process is different and brittle. The actual effect of carbon fiber metal surface treatment. The most important thing to remind everyone is that the carbon fiber electrolysis metal surface treatment can also choose a mixed method. For the first time, an acid-alkaline electrolyte solution is used, and for the second time, a partial alkaline electrolyte solution is used.
3. Low temperature plasma air oxidation method. Using low-temperature plasma purification equipment or microwave heating low-temperature plasma to carry out metal surface treatment on carbon fiber is also a key processing technology. This processing technology is characterized by zero pollution from gas-solid reflection, and the solution time and actual effect are good. However, the plasma technology must be vacuumed, so the machinery and equipment are complicated. This method is still in the scientific research and sound link, but it solves the actual effect. In general, the actual effect is quite satisfactory.
In addition to the above three carbon fiber surface treatments, there are also various solutions such as liquid-phase air oxidation, electrolytic air oxidation, high-efficiency liquid-phase air oxidation, electropolymer method, liquid-phase accumulation method, and surface coating. Therefore, different carbon fiber production and processing manufacturers will choose different methods, so the processing technology is very different, and it seems very important for customers to choose a manufacturer with more exquisite production technology.
