Aluminum can be divided according to the use of: 1, doors and windows of aluminum doors and windows for construction; 2, CPU radiator dedicated radiator aluminum profile; 3, aluminum alloy shelf type.
According to the alloy composition can be divided into: 1, anodized aluminum; 2, electrophoretic coating of aluminum; 3, powder sprayed aluminum; 4, wood grain transfer aluminum; 5, planed aluminum.
The author takes the industrial aluminum profile as an example, and details its specifications: In addition to the large-size profiles, the specifications of the industrial aluminum profiles are more of the small and medium specification profiles, occupy a larger proportion in the industrial profiles, and have more specifications and smaller batch sizes. It is its characteristics, and some industries have not yet developed materials, which may have more potential than large profiles. Appropriate consideration should be given to slow down the construction of large-scale and extra-large extrusion production lines. There are more than 10 large-scale and extra-large aluminum extrusion material production lines that have been built and under construction in China, and the production capacity exceeds 100kt/a, which greatly exceeds the demand for large-scale extrusion materials in the near future. In recent years, large-scale and extra-large extrusion production lines have been mostly constructed with rail vehicle profiles. However, the demand for rail vehicle profiles is limited. After several extrusion production lines are completed, there is a large difference between demand and production capacity. Can not increase the development of demand for large profiles in other industries, will inevitably lead to fierce competition in the rail vehicle profile production line, and now on the large extrusion production line may make companies in a very passive situation. Increase the development of industrial aluminum profiles. The demand for industrial aluminum profiles is limited on the one hand by the overall industrial level, on the other hand it is also related to the lack of development efforts.
Oil painting is a kind of painting made on canvas (linen cloth), cardboard or wood board by blending pigments with fast drying vegetable oils (linseed oil, poppy oil, walnut oil, etc.). The thinner used in painting is volatile turpentine oil and dry linseed oil. The paint attached to the screen has a strong hardness, which can maintain the luster for a long time after the screen is dry. By virtue of the hiding power and transparency of pigments, the painted objects can be fully displayed, with rich colors and strong three-dimensional texture. Oil painting is one of the main types of western painting.
