Aluminum Profile Hardness Control and Coloring
1, Aluminum Profile aging furnace temperature settings and control: Usually, the aging furnace temperature and aging furnace surface temperature there is a certain error, set the table temperature according to the actual temperature of the furnace to be set, China's renewable copper technology and Market and pay close attention to the aging furnace temperature fluctuations.
2, industrial Aluminum Profile aging insulation: to strictly in accordance with the requirements of the process to time, the insulation time to be appropriate to prevent the aging or overtime caused by the hardness is not enough.
3, Aluminum Profile extrusion frame can not be too dense, between the material and the material should be separated, especially the non-ventilated small material, thick material interval is even greater, pipe material and small material, sheet material together when a box , Pipe material to put the following is conducive to the regular cycle of air supply.
When the aluminum profile of the alloy in the silicon content is low, the impact of iron is more obvious, silicon high to a certain extent, reduce the harmful effects of iron, then iron and silicon to form AlFeSi intermetallic compounds, but also consumed Part of the excess silicon. Iron is mainly due to the color of the formation of iron and aluminum to form a sharp or rod-like organization, ranging from a few microns to tens of microns, the electrode potential and aluminum is different, it affects the oxidation uniformity and continuity of color, but also the oxide film luster And the transparency is reduced, affecting the coloring effect
Industry access threshold will improve the aluminum alloy processing industry investment scale, standardize the industry disorderly competition, to focus on product quality, energy saving enterprises to create a good competitive conditions.
With the national industrial policy, industrial restructuring and consumer demand for product quality improvement, aluminum processing industry, extensive, low value-added status of the gradual change.
Aluminum products will continue to increase the internal integration of the industry, some products positioning middle and low market and production technology and equipment technology backward enterprises will face the market, capital, cost, energy consumption, technology and other aspects of the pressure, part of the production process leading , Excellent quality, market-oriented, innovative ability, management of advanced enterprises will occupy more market share.
With the integration of the Aluminum Profile industry, the merger of the Aluminum Profile will accelerate, and the enterprise will develop toward the group, the large, the specialization and the brand. Product technology development, quality management, sales and service, such as the overall strength of enterprises become bigger and stronger key factors.
Aluminum Profile surface treatment methods generally exist anodizing, electrophoresis coating and powder coating three kinds of treatment, each way has its own advantages, occupy a considerable market share.
Powder coating has the following advantages:
1, the process is relatively simple, mainly due to the production process of the main equipment of the automatic accuracy of the improvement of some of the major technical parameters can be achieved microcomputer control, effectively reduce the difficulty of process operation, while greatly reduce the auxiliary equipment;
2, Aluminum Profile of the high yield, under normal circumstances, if the measures properly, to maximize control of the production of substandard goods;
3, energy consumption significantly reduced, in the ordinary anodizing, electrophoretic coating production process, water, electricity consumption is quite large, especially in the oxidation process. Rectifier output current can reach between 8000 ~ 11000A, the voltage between 15 ~ 17.5V, coupled with the machine's own heat, need to keep using circulating water for cooling, tons of power consumption is often around 1000 degrees, While the reduction of ancillary facilities can also reduce some of the power consumption;
4, the degree of pollution of water, the atmosphere to reduce the alkali, sulfuric acid and other liquid organic solvents are no longer used to reduce water and air pollution, but also effectively improve the Aluminum Profile and environmental protection products as the competitive strength of steel profiles, accordingly Reduced some production costs;
5, Aluminum Profile workers significantly reduced the labor intensity, due to the use of automated assembly line operations, feeding methods and the use of fixtures have been significantly simplified, improve production efficiency, but also reduce labor intensity;
