Definitions

  • the present invention relates to an aquaculture net for seawater made of a copper alloy material and a method for preparing said copper alloy material. More specifically, the present invention relates to an aquaculture net for seawater made of a copper alloy material comprising 25% to 40% by weight of zinc (Zn), 0.5% to 10% by weight of manganese (Mn), 0.1% to 5% by weight of nickel (Ni) and the remainder of copper (Cu) and a method for preparing said copper alloy material.
  • the copper alloy material for an aquaculture net for seawater further comprises, in an amount of 1% by weight or less, at least one element selected from the group consisting of Sn, Al, Si, Co, Fe, P, Mg, Pb and Ca.
  • an aquaculture net made of iron hereinafter, referred to as an iron net
  • an aquaculture net made of a chemical fiber hereinafter, referred to as a chemical fiber net
  • marine organisms such as shellfish or algae are readily adhered to the net and the mesh of the net is clogged, causing a deterioration in flow of tidewater, thus limiting supply of oxygen or water-in nutrients to the farm, and thus causing a deterioration in production efficiency and aquaculture yield.
  • the aquaculture net requires superior strength, since it should be resilient to certain unforeseen circumstances such as tides of seawater and typhoons.
  • the chemical fiber net has a disadvantage of low strength, as compared to the metal net.
  • metal nets require sufficient corrosion resistance to seawater, since they are inevitably exposed to ionic components such as salts present in the seawater.
  • conventional metal nets are readily corroded by seawater.
  • other metal nets made of a metal-containing material have economic efficiency problems due to high cost. For this reason, metal nets are preferably made of a material which can be manufactured at a low cost.
  • Aquaculture nets made of a copper alloy material under recently developed under such a circumference can prevent adhesion of marine organisms thereto due to anti-fouling property derived from silver and copper ions, thus reducing clogging the mesh of the aquaculture net and thereby somewhat solving the high-cost problem caused by deterioration in production efficiency or yield of cultured fish.
  • copper alloys which satisfy the requirements of sufficient strength, corrosion resistance to seawater and anti-fouling property and are made of a cheap material.
  • Korean Laid-open Patent Publication No. 1993-0019841 discloses a copper alloy material based on Cu-Al-Ni, which has an insufficient strength for use as a structure for use in the seawater, and low economic efficiency, due to use of relatively expensive nickel (Ni).
  • Korean Laid-open Patent Publication No. 1999-002539 discloses a copper alloy material based on Cu-Al-Zn-Mn-Fe in which aluminum is present in an amount of 5% to 5.3% by weight and zinc is present in an amount of 10% to 20% by weight, thus making it difficult to secure sufficient processability, and in which iron is present in an amount of 2% to 4% by weight, thus making it difficult to secure sufficient corrosion resistance.
  • An object of the present invention devised to solve the problem lies on a copper alloy material for an aquaculture net for seawater which has superior mechanical properties including sufficient strength, superior ductility and low brittleness, and exhibits high corrosion resistance to seawater and anti-fouling property.
  • Another object of the present invention devised to solve the problem lies on a method for preparing the copper alloy material.
  • a copper alloy material for use for an aquaculture net for seawater comprising 25% to 40% by weight of zinc (Zn), 0.5% to 10% by weight of manganese (Mn), 0.1% to 5% by weight of nickel (Ni) and the remainder of copper (Cu).
  • the copper alloy material can further comprise, in an amount of 1% by weight or less, at least one element selected from the group consisting of Sn, Al, Si, Co, Fe, P, Mg, Pb and Ca.
  • a method for preparing a copper alloy material for an aquaculture net for seawater comprising: producing an ingot comprising 25% to 40% by weight of zinc (Zn), 0.5% to 10% by weight of manganese (Mn), 0.1% to 5% by weight of nickel (Ni) and the remainder of copper (Cu); annealing the ingot at 600°C to 900°C for 30 minutes to 12 hours, followed by hot extruding and drawing; quenching the resulting product, followed by cold drawing; annealing the resulting product at 500°C to 800°C for 30 minutes to 12 hours; and cold drawing the resulting product.
  • Zn zinc
  • Mn manganese
  • Ni nickel
  • Cu copper

  • Final cold drawing ratio may be 10% to 90%.
  • an aquaculture net for seawater manufactured from a copper alloy material for seawater comprising 25% to 40% by weight of zinc (Zn), 0.5% to 10% by weight of manganese (Mn), 0.1% to 5% by weight of nickel (Ni) and the remainder of copper (Cu).
  • the present invention provides an aquaculture net for seawater made of a copper alloy material, which has superior mechanical properties and exhibits superior high anti-fouling property and corrosion resistance to seawater. Further, the present invention provides a method for preparing the copper alloy material.
  • copper alloy material for seawater or “copper alloy material for use in the seawater,” as used herein, refers to a copper alloy material which is partially or entirely immersed in the seawater for a long period and, for example, a fish net for aquaculture.
  • the present invention is directed to a an aquaculture net for seawater made of copper alloy material comprising 25% to 40% by weight of zinc (Zn), 0.5% to 10% by weight of manganese (Mn), 0.1% to 5% by weight of nickel (Ni) and the remainder of copper (Cu).
  • zinc (Zn) is present in an amount of 25% to 40% by weight, based on the weight of the copper alloy material.
  • Zinc improves the strength and hardness of the copper alloy material obtained by alloying a copper metal and enhances heat resistance.
  • the second phase, beta ( ⁇ ) phase when zinc is less than 25% by weight, sufficient hardness cannot be secured and economic efficiency decreases due to an increased amount of copper with respect to zinc, and when zinc exceeds 40% by weight, the second phase, beta ( ⁇ ) phase, indicating brittleness of materials in the obtained copper alloy material, increases and ductility is thus deteriorated, thus causing problems, such as cracking during processing.
  • zinc is preferably present in an amount of 35% to 40% by weight.
  • manganese (Mn) is present in an amount of 0.5% to 10% by weight, based on the weight of the copper alloy material.
  • the second phase, beta ( ⁇ ) phase increases and ductility is thus deteriorated, as the content of zinc in the copper alloy material increases.
  • manganese reduces deterioration in ductility.
  • the content of manganese is less than 0.5% by weight, reduction of ductility through addition of manganese is insufficient, and when the content exceeds 10% by weight, the materials are brittle.
  • nickel is present in an amount of 0.1% to 5% by weight, based on the weight of the copper alloy material. Nickel improves hardness of the obtained copper alloy material. When the content of nickel is less than 0.1% by weight, hardness is not sufficiently improved, and when the content of nickel exceeds 5% by weight, hardness improvement is slowed. Although nickel is added in an amount of 5% by weight or higher, considerable improvement in hardness cannot be obtained. Accordingly, as the amount of nickel increases, economic efficiency is considerably deteriorated.
  • copper (Cu) is a main component.
  • the copper is present in an amount of the remainder, except for which the afore-mentioned other components are present in amounts defined above.
  • the copper alloy material for seawater may further comprise, in an amount of 1% by weight or less, at least one element selected from the group consisting of Sn, Al, Si, Co, Fe, P, Mg, Pb and Ca.

  • the further added element exhibits effects, comparable to the copper alloy material of the present invention, without causing in deterioration in hardness and softening resistance of the copper alloy material and having a negative effect on corrosion resistance to seawater and eluted amount of ions.
  • the copper alloy material in accordance with the present invention exhibits considerably improved corrosion resistance to seawater when a structure for seawater made of the copper alloy material is used in the seawater, compared with a conventional copper alloy material in which a corrosion promoter is readily produced by seawater.
  • the eluted amount of copper ions in the copper alloy material should be 60% or higher, based on the eluted amount of copper ions of pure copper, in order to impart sufficient anti-fouling property to the structure for seawater manufactured from the copper alloy material.
  • the eluted amount of copper ions of copper alloy material is 60% or less of the eluted amount of copper ions of pure copper, the pollution prevention effects cannot be sufficiently realized.
  • the amount of copper ions eluted from the copper alloy material in the seawater should be 415.8 mg/m 2 /day or more, in order to secure sufficient antibacterial properties, since the amount of copper ions eluted from pure copper in the seawater is about 693 mg/m 2 /day.
  • the copper alloy material in accordance with the present invention exhibits an amount of eluted copper ions which is 60% or more of copper ions eluted from pure copper.
  • the strength of the copper alloy material according to the present invention may be evaluated in terms of hardness and softening resistance.
