Aluminum honeycomb panels using composite honeycomb structure, the selection of high quality aluminum alloy or 5052AH14 3003H24 high manganese alloy aluminum sheet for the substrate aluminum honeycomb panels, and aluminum honeycomb core composite molding hot. Aluminum honeycomb panels from the panel material, shape, joints, install the system to color, surface treatment provides a wealth of choice for architects rod, can demonstrate wealth of roofing performance results, excellent design freedom. It is a convenient construction, the overall performance desired, the insulation effect significant new material, its superior performance to attract people's attention. There is no standard size aluminum honeycomb panels, all boards are ordered according to design drawings made by the plant, widely used in building wall decoration (especially for high-rise building) interior ceiling, wall partitions, doors and insulation compartments , billboards and so on the field. The product will be injected into the green, environmental protection, energy saving fresh impetus China's building materials market. Welding difficulty (1) easily oxidized. In the air, the aluminum oxide combined with easy to produce a dense aluminum oxide film (thickness of about 0.1-0.2μm), high melting point (about 2050 ℃), far more than the melting point of aluminum and aluminum alloys (about 600 ℃ or so). Alumina density 3.95-4.10g / cm3, aluminum is approximately 1.4 times the surface of the aluminum oxide film of easy absorption of moisture direct 104 rod, welding, it prevents fusion of the base metal, can easily form pores, slag, incomplete fusion and other defects, performance degradation caused by welding. (2) easy to produce pores. The main reason porosity of aluminum and aluminum welding is hydrogen, since large amounts of hydrogen soluble liquid aluminum, and solid aluminum hardly dissolved hydrogen, the production number 104 rod when the rapid cooling and solidification of the bath temperature, hydrogen late Yi the production of aluminum rod 108, easily aggregate to form pores in the weld. Hydrogen is difficult to completely avoid the holes, many sources of hydrogen, electric arc atmosphere of hydrogen, aluminum, wire surface oxide film adsorbed moisture in the air and so on. Practice has proved that, even if the argon gas by GB / T4842 standards, purity of 99.99%, but when the moisture content of 20ppm, there will be a lot of dense pores, when the relative humidity exceeds 80%, if not take heat and other measures, the weld will obviously appear pores. At the same time, using a small welding current slow increase weld cooling time, and use wire arcs puddle agitation, can better help the gas discharge bath. Rod | rod production number 108 | Sun Shine scrap metal recycling (quality businessmen) recovered from the Linyi City Shengxin scrap metal Limited. Linyi City Shengxin scrap metal recycling Ltd.
