Description

Technical Field

[0001] The invention relates to a method for manufacturing and processing metal aluminum. Background Art

[0002] Aluminum is the most abundant metal element in the earth's crust and one of the lightest metals. Its density is about one-third of that of copper and iron. It has good thermal conductivity, electrical conductivity and ductility, and is chemically active. It is easily oxidized in the air to form a dense protective film that is corrosion-resistant, but it cannot react with strong alkaline solutions. Pure aluminum has low strength, poor plasticity, and good casting properties. It is widely used in the aviation industry and electrical industry, such as manufacturing aircraft and rockets; aluminum alloys can be used as building decoration materials, wires and cables, containers, cans, pipes, rivets, nuts, etc.

[0003] The existing aluminum metal has a less than smooth surface, is of a single color, and consumes a lot of energy during the production process. Summary of the invention

[0004] The purpose of the present invention is to provide a method for manufacturing and processing metal aluminum to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a method for producing and processing metallic aluminum, comprising the following steps: adding metallic aluminum into an electric furnace or a charcoal burning furnace to melt it into a liquid state; pouring it into large polypropylene beads soaked in water, then pouring water to cool it down, fishing it out, and coloring it.

[0006] Preferably, the coloring is performed by electroplating.

[0007] Preferably, the coloring is performed by acid washing.

[0008] The invention has the advantages that: the invention pours the metal aluminum into the polypropylene foam beads soaked in clean water, so that the melted metal aluminum is quickly cooled and formed, and then the residual fire is extinguished with water and the aluminum block is fished out to obtain the metal aluminum block of the desired shape. Since the metal aluminum absorbs heat during the cooling process, the energy saving effect is achieved. At the same time, the use of polypropylene foam beads instead of traditional sand can reduce environmental pollution and improve the appearance quality of the product. In addition, the product can be colored by electroplating or pickling to increase the color richness and visual impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] For the purpose of the following detailed description, it should be understood that the present invention may adopt various alternative changes and step sequences, unless expressly specified to the contrary. In addition, except in any operating examples, or otherwise indicated, all numbers representing the amount of ingredients used in the specification and claims should be understood to be modified by the term "about" in all cases. Therefore, unless otherwise indicated, the numerical parameters set forth in the following specification and the attached claims are approximate values ​​that vary according to the desired performance to be obtained by the present invention. At least it is not intended to limit the application of the doctrine of equivalents to the scope of the claims, and each numerical parameter should at least be interpreted according to the number of reported significant figures and by applying ordinary rounding techniques.

[0011] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values ​​set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0012] In addition, it should be understood that any numerical range described herein is intended to include all subranges subsumed therein. For example, a range of "1 to 10" is intended to include all subranges between (and including) the stated minimum value of 1 and the stated maximum value of 10, i.e., having a minimum value equal to or greater than 1 and a maximum value equal to or less than 10.

[0013] Example 1

[0014] Take 50g of metal aluminum and put it into an electric furnace or a charcoal furnace to heat it to a molten state (temperature is about 660℃), then pour it into the pre-prepared polypropylene bubble beads, then pour water to cool down, take it out, take it out after it is completely cooled, and color it.

[0015] Preferably, the coloring is performed by electroplating.

[0016] Example 2

[0017] Take 70g of metal aluminum and put it into an electric furnace or a charcoal furnace to heat it to a molten state (temperature is about 660℃), then pour it into the pre-prepared polypropylene bubble beads, then pour water to cool down, take it out, take it out after it is completely cooled, and color it.

[0018] Preferably, the coloring is performed by acid washing.

[0019] Example 3

[0020] Take 100g of metal aluminum and put it into an electric furnace or a charcoal furnace to heat it to a molten state (temperature is about 660℃), then pour it into the pre-prepared polypropylene bubble beads, then pour water to cool it down, take it out, wait for it to cool completely, and then color it.

[0021] Preferably, the coloring is performed by acid washing.

[0022] The raw materials used in the above embodiments can all be purchased on the market, are cheap and easy to buy, and the processing process is relatively simple, without the need for complex equipment and technical support.

[0023] Comparative Example 1

[0024] The difference from Example 1 is that the metal aluminum is directly poured into the sand and allowed to cool and form. As a result, it is found that the surface of the product is rough and cracked, and the appearance is poor.

[0025] Through testing and comparison, it can be seen that the product of the present invention has a smoother and more delicate surface, more uniform color, and no obvious flaws and defects than the metal aluminum produced by traditional processes, and the overall quality has been significantly improved.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
