Although granite, marble, and ceramic tiles have smooth surfaces and good decorative properties, they are heavy and fragile, which brings difficulties to transportation and construction, and has poor sound insulation effect, so they cannot be recycled; while gypsum board has non-combustibility, sound insulation, Heat insulation, cheaper price, but not water-resistant, deformed after absorbing water, easily affected by the weather, the surface layer will turn yellow when it rains continuously, usually after 2 to 3 years, it will start to change color, and the strength is not strong; the board is flammable and easily Fires are caused, and wood resources are limited; the aluminum-plastic composite board has uniform color, smooth surface, and is easy to manufacture, but the disadvantage of this kind of composite board is that the middle layer of the composite b...

Embodiment Construction
[0021] The invention discloses a processing method of foamed aluminum material, which has a mold container, which is characterized in that an air outlet is formed at the bottom of the mold container, and the specific processing steps are: ① Put 40% to 60% of granular salt in the mold container As a filler, take the best value of 50%; ②, roasting filler: put the mold container with filler into the roasting furnace, and heat it up to 500-650°C at a rate of 5°C per minute, the best is 630°C , keep warm for 30 minutes, remove the moisture in the granular salt, and then air-cool; ③, take out the roasted granular salt, put it on a sieve for sieving to obtain the required size and uniform granular salt; ④, put the granular salt again When loading the mold with salt, it should be loaded and compacted in layers. The thickness of each layer is about 50mm, spray a little water mist, and then compact; The temperature is preheated for 60 minutes, preferably 700°C, to achieve sufficient pre...

Abstract
The invention relates to a processing method for foamed aluminum, including mould vessel. The mould vessel has air outlet on the bottom, the processing steps are: (1) putting 40% to 60% of granulated salt into the mould vessel as filling; (2) heating to 500 DEG C to 650 DEG C at a speed of 5 DEG C per minute, keeping the temperature for 30 minutes and then air cooling; (3) selecting uniform granulated salt according the need; (4) mould feeding the filling again and compacting; (5) preheating 60 minutes at a temperature of 600 DEG C to 750 DEG C; (6) with aluminum liquid casting temperature being 700 DEG C to 750 DEG C, applying 0.2 MPa to 0.3 MPa seepage force to the upper side of the aluminum liquid, keeping the pressure for 3 minutes to 8 minutes until aluminum liquid oozes the air outlet; (7)cooling to a temperature below 200 DEG C to demould; (8) cutting; and (9) washing the filling. The upper side of the foamed aluminum material or the upper and lower composite metal plates can be used for building, transport facility, sound absorbent, furniture plate, etc.
Description
technical field [0001] The invention relates to a processing method of foamed aluminum material and the application of the material. Background technique [0002] With the improvement of living standards, people pay more and more attention to the decoration materials of interior decoration (such as wall panels, floors, ceilings, etc.), and now they mainly use granite, marble, tiles, gypsum boards, wood boards, aluminum-plastic composite boards, etc. Material. Although granite, marble, and ceramic tiles have smooth surfaces and good decoration, they are heavy and fragile, which brings difficulties to transportation and construction, and has poor sound insulation effect, so they cannot be recycled; while gypsum board has non-combustibility, sound insulation, Heat insulation, cheaper price, but not water-resistant, deformed after absorbing water, easily affected by the weather, the surface layer will turn yellow when it rains continuously, usually after 2 to 3 years, it will s...
