Improve the level of automation can increase in production some, but limited number, for example,[link widoczny dla zalogowanych], the cell Qingtongxia Cleveland Aluminum Co., Ltd. ABB's control system to switch system of the future, the current efficiency increased only 2 percentage points, ie from 93% to 95%. In the current technical conditions, meant to make the current efficiency increased to 96.5% or higher is almost impossible. 4 large aluminum companies how to calculate the capacity, output and sales income? The question is very simple, internationally common calculation method, or do not follow the standard method will be chaos, he said that my primary aluminum production is the first in the world Another person said you do not so much, can not be considered first. Usually refers to production capacity, production and sales revenue is interest (equity) part of the international community is usually calculated in this way, not referring to the management of production capacity, production and sales revenue. For example, Cleveland Aluminum Co.,[link widoczny dla zalogowanych], Ltd., accounted for 51% of Alcan shares by its management, production capacity of 150kt / a, Alcan have aluminum production capacity, production and sales can only be calculated at 51% But the management capacity and 100% of production may, however,[link widoczny dla zalogowanych], said a company of international capacity and its share of production are the means that a considerable portion of shares. China may be more complicated calculation, but in comparison with foreign companies, in the calculation of production capacity, output size,[link widoczny dla zalogowanych], according to interest a certain capacity, output and sales revenue, or not in the same starting line comparison, you can not draw the right conclusions. What is CTP 5 aluminum plate? CTP (computer.to.plate) version is actually also a PS version of the software system can also be called digital offset printing layout of the PS version, this version has been in the industrial countries is common, accounting for the mainstream of the printing industry. CTP version used in the manufacture of the aluminum plate has more stringent requirements, such as flatness of preferably less than 1I. CTP version of the manufacturing process: aluminum oxide of a brush handle and deal with a pro-light-sensitive layer of a coating. PS version of the same ordinary, CTP version of the photosensitive layer can be divided into two kinds of thermal and sensitive, but light and heat sensitivity is not the same. For example, the ordinary PS version of photosensitive violet light on the wavelength of light between the 370nnq ~ 460nnl very sensitive to light, while the CTP version of the photosensitive layer Quedui 432nnq ~ 500nnq wavelength of light is very sensitive. Because of high quality aluminum plate CTP, so the price is about more than ordinary high-grade aluminum with a PS version of the high of about 5,000 yuan / t. CTP production in China is not presently aluminum plate, should build a professional production base. In the high-precision aluminum sheet, it is a crown jewel. 6 magnesium alloy sheet in the printing industry for what purpose? Magnesium alloy sheet is not in the printing industry for the manufacture of Ps version and CTP version, it is not used to make lithographic printing of edition, but for the manufacture of specialty printing, such as printing money, relief printing, cardboard printing, copying and other fine works of art, this version also known as intaglio, lithography Edition (photoetch.ing, PE) and so on. Magnesium thickness 8mE ~ 10mE, etching depth of about 3mE. Etched magnesium plate with the special print has many advantages: corrosion, (electric etching) faster than copper, zinc, fast, line symmetry, the image is clear, strong anti-Indian. Russia and the U.S. production of magnesium plate used for plate making, the United States there are 2 plant, the British Queen to create magnesium plant (ElectronMagnesium) also produces a small amount. But the market is limited, the printing industry worldwide in 2005, would only 2kt magnesium plate around. 7 What is \T6 extruded aluminum, especially aluminum railing structure of a call, not a technical term, there is no such international name for. Product performance and surface state and the regular 6061. T6 alloy, like, no features, do not think that is what the new alloy, and what do not think that has some special properties of special treatment. I suggest in the future can not so called, in order to avoid unnecessary confusion and misunderstanding, not to facilitate foreign exchange. \simply can not do. Of course, if after a special surface treatment, surface hardness of aluminum and aluminum alloy can be achieved with ordinary steel or even a significant higher, but the process complexity,[link widoczny dla zalogowanych], high cost, not suitable for dealing with structural materials.
