The development situation of solar aluminum profile

After more than 20 years of development, enterprises producing solar aluminum profiles have generally realized that it is increasingly difficult for them to survive, develop and grow according to traditional chuan tǒng production Technology and enterprise profit points. At present, the technical added value of products is still relatively low. And want to improve the product competitiveness of building materials, be about to break through existing technical bottleneck, new product development, raise production efficiency and strengthen the respect such as technology control and improvement begin, raise the core competitiveness of enterprise and product thereby. Specific measures (indicative solutions to the problem) are as follows:

1, improve the level of mold design, processing and manufacturing

At present, most of China's solar building aluminum manufacturers use single-hole die extrusion, the application of porous die is limited to small tonnage extruder to produce small section profiles. For ordinary building profile products, usually the output of a single section is large, many batches, therefore, with the conditions of the use of porous die extrusion, which requires the innovative consciousness and processing equipment and precision of mold designers to a new level, so as to improve the efficiency of extrusion production. In this respect, we are far behind our European and American counterparts.

2, improve the melt quality (Mass) of aluminum bars

Some aluminum production companies, due to the lack of attention to the quality of casting products (Mass), extrusion production process product quality problems (Emerson), ingot quality causes often account for about 50%. Solar aluminum plate titanium plating process, belongs to the coating technology, it is in the conventional titanium plating process on the basis of the increase of pre-plating and electroplating process steps, pre-plating process is the activation of the plated parts in salt and hydrochloric acid solution for chemical treatment. Solar aluminum frame is aluminum rod through hot melting, extrusion, so as to get different cross-section shape of aluminum material. The production process of aluminum profile mainly includes three processes: casting, extrusion and coloring. Among them, the color mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing and other processes. Combined with the homogenization effect, the influence on extrusion speed accounted for about 70%. According to observation, the process control in most solar aluminum production workshops is not ideal, the refining effect of melt is poor, and the problem of "how to prevent secondary pollution of melt after furnace" is not paid enough attention.

3. Adopt advanced extrusion technology

Solar aluminum frame is aluminum rod through hot melting, extrusion, so as to get different cross-section shape of aluminum material. The production process of aluminum profile mainly includes three processes: casting, extrusion and coloring. Among them, the color mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing and other processes. Luo Baihui believes that on the basis of optimizing the mold design, improving the material properties of the mold and improving the surface treatment effect, the use of homogenized high quality aluminum rod and rapid heating can achieve the purpose of "low temperature rapid extrusion". Under the condition of ensuring the extrusion outlet temperature reaches more than 500℃, the bar temperature is controlled in a relatively low temperature range.
