China’s construction products investigation analysis
20 years of development, China construction profiles production domain to develop a large number of field technical personnel and workers, has abundant practical experience. However, in the traditional production technology and enterprise profit point for enterprise survival and development, expansion, is becoming more and more difficult. To improve the building hardware products to improve product competition the added value of the technology, so to break the existing technical bottleneck, developing new products, improve the production efficiency and strengthening technology control and improvement from the aspects such as, so as to improve the enterprise and the core of the product competitiveness. Specific measures are as follows:
1, develop energy-saving aluminum Windows and curtain wall, and new products
China’s energy shortage is not in the near future can ease, therefore, new product development to focus on energy saving the topics. The aluminum door window is mainly has two aspects: one is the broken bridge (note glue) heat insulation window development, the present state of affairs, the popularity of this window is an inevitable trend. But the consideration to the economic development of our country present situation, not all people use up broken bridge (note glue) heat insulation window. Therefore, on the other hand is ordinary flat open, push-pull window structure optimization and improvement. At present many ordinary casement Windows and push-pull window, from improving air tightness and reduce the amount of use aluminium, in the structure is there a large space of improvement, so as to reduce the hot and cold air convection degree and the cost of production. Aluminum curtain wall, basically be broken bridge (note glue) curtain wall structure, this aspect of the domestic curtain wall structure is less, secondly, by increasing the plastic accessories make curtain wall component realize flexible contact inside and outside, also can have certain effect in energy saving.
2, improve the mould design, processing and manufacturing level
At present our country building, the aluminum manufacturer most use a pucker extrusion die, the application of the porous mold limited to small tonnage extrusion machine production small section profiles. For ordinary construction profiles products, usually a single sections of large output, batch and, therefore, have the extrusion die of porous conditions, this requires mold designers innovation consciousness and processing equipment and precision to a new level, so as to improve the efficiency of the extrusion production. This way, we walked with Europe and the difference.
3, improve the quality of the bar melt
Part of the aluminum production enterprise, due to insufficient attention to product quality casting, extrusion production processes, the product quality problems occur, the cause of which tend to bubble quality accounted for 50%. And with all the fire in its effect, the influence of the extrusion speed of about 70%. According to the author observation, most of the manufacturer of the aluminum smelting process control of workshop is not so ideal, the melt refining effect is poorer, after the furnace of how to prevent melt second pollution problems caused by not paid enough attention.
4, the use of advanced extrusion process
In optimizing mold design, improve die material properties and surface treatment effect, and on the basis of using the aluminum awning window are fire and rapid heating, can achieve the purpose of low temperature rapid extrusion, ensure extrusion temperature reaches 500 ℃ above export, the great temperature control in the low temperature range. At present, the individual manufacturer using this method, and have achieved good effect, significantly raise the squeezing the individual output.
