Definitions
- the present invention relates to a method of manufacturing a lattice member used for forming a cage for a poultry house, and a lattice member manufactured by the manufacturing method.
- a layer system poultry house In poultry farming facilities, a layer system poultry house is often used, in which cage rows in which cages containing a plurality of chickens are arranged in a row in the horizontal direction are stacked in a plurality of stages in the vertical direction.
- Each cage is formed by using a lattice member in which wire rods are assembled vertically and horizontally.
- the wire rod a wire formed of steel such as low carbon steel (soft steel) is generally used.
- the cage is always exposed to chicken excrement. And in order to keep it clean, the cage is washed with a large amount of water and disinfected. Therefore, the cage formed of steel wires may be corroded by components, disinfectants, and moisture contained in the excrement.
- galvanization In order to improve the corrosion resistance of steel products, galvanization is generally performed.
- the anticorrosive action of galvanizing suppresses the corrosion of the main material because zinc contained in the surface layer (plating layer) elutes ahead of the main iron because zinc has a higher ionization tendency than iron. It is to do. For this reason, there has been a concern that zinc eluted from the plating layer may affect chickens and eggs.
- the present invention provides a method for manufacturing a lattice member for a poultry house cage that has enhanced corrosion resistance and has a reduced effect on chickens and eggs, and a lattice member manufactured by the method. Providing is an issue.
- a method for manufacturing a lattice member for a poultry house cage according to the present invention (hereinafter sometimes simply referred to as “manufacturing method”) “After applying hot-dip zinc-aluminum plating on steel wires and welding them vertically and horizontally to form a lattice structure, or by welding steel wires vertically and horizontally to form a lattice structure and applying hot-dip zinc-aluminum plating And then coated with resin ".
- the lattice member for a poultry house cage (hereinafter, simply referred to as “lattice member”) having the following configuration is manufactured. That is, “A lattice structure in which steel wires covered with a zinc-aluminum alloy layer intersect vertically and horizontally, or a lattice structure in which steel wires that intersect vertically and horizontally are covered with a zinc-aluminum alloy layer. It is a lattice member having a resin layer as the outermost layer.
- the crossed portion should have a welded metal layer as the outermost layer. It becomes. Therefore, there is a possibility that the lattice structure may be collapsed due to the corrosion of the metal layer at the intersection, or the corrosion may spread over the entire lattice member starting from the corrosion at the intersection.
- the manufactured lattice member since it is covered with a resin after forming a lattice structure, the manufactured lattice member has a resin layer as an outermost layer in all portions including the intersection. Therefore, corrosion of the lattice member is effectively suppressed by the resin layer.
- the poultry house cage formed by the lattice members Even if the outermost resin layer is cracked or partially peeled, it has a zinc-aluminum alloy layer below it. .
- the zinc-aluminum alloy layer in addition to the zinc suppressing iron corrosion of steel wires, aluminum forms an inactive thin film (passive film). Therefore, by having the zinc-aluminum alloy layer, the corrosion resistance of the steel wire is enhanced while suppressing the elution of zinc.
- the resin layer is partially cracked or peeled off, most of the other portions have the resin layer on the zinc-aluminum alloy layer, so that the possibility of zinc elution is very small.
- the lattice member manufactured by this manufacturing method has two barriers, that is, a resin layer and a zinc-aluminum alloy layer, and the resin layer is the outermost layer.
- the elution of zinc which is concerned about the influence, is suppressed and has high corrosion resistance.
- the manufacturing method of the lattice member for the poultry house cage according to the present invention is as described above. “The resin is polybutylene terephthalate and is coated by a fluidized dip coating method”.
- polybutylene terephthalate Since polybutylene terephthalate has a low water absorption rate, it is suitable as a material for the outermost layer of a member for a poultry house cage that is washed with a large amount of water. In addition, polybutylene terephthalate has high resistance to chemicals and organic solvents, and is therefore suitable as a material for the outermost layer in a member for a poultry house cage to which a disinfectant is sprayed. Furthermore, since polybutylene terephthalate has high wear resistance, it is suitable as a material for the outermost layer in a member for a poultry house cage that often comes into contact with chicken beaks and claws.
- a method for manufacturing a lattice member for a poultry house cage that has improved corrosion resistance and has a reduced effect on chickens and eggs, and a lattice member manufactured by the manufacturing method, Can be provided.

- the flow is performed in the order of wire drawing P1, hot dip zinc-aluminum plating P2, processing P3 into a lattice structure, and coating P4 with resin. That is, it is an example of “post-processing”.
- Drawing P1 The steel wire 10 is obtained by cold drawing by passing a steel rod through a die.
- low carbon steel soft steel defined in Japanese Industrial Standard (JIS G3505) is used as a steel rod, and the steel wire 10 has a diameter of 2.0 mm to 2.5 mm.
- Hot-dip zinc-aluminum plating P2 After the steel wire 10 is pretreated, it is immersed in a molten zinc-aluminum bath, and the surface of the steel wire 10 is covered with a zinc-aluminum alloy layer 11 which is a plating layer.
- plating is performed with 90 mass% zinc-10 mass% aluminum, which has extremely high corrosion resistance.
- the thickness of the plating layer is 30 ⁇ m to 50 ⁇ m, there is no excess or deficiency with respect to the corrosion resistance required for the cage for a poultry house.
- pre-processing can be performed in order of degreasing, water washing, pickling, water washing, flux processing, and drying, for example.
- Processing to lattice structure P3 The steel wire 10 is crossed vertically and horizontally, and the intersecting portion 20 is welded to form a lattice structure. In welding, the same material as the steel wire 10 can be used as a filler material.
- Coating with resin P4 In this embodiment, polybutylene terephthalate is used as the resin, and coating is performed by a fluidized dip coating method. Specifically, the powder of polybutylene terephthalate is flowed by sending compressed air, and the preheated lattice structure is immersed in the flowing powder. Thereby, the lattice structure is covered with the resin layer 12 of polybutylene terephthalate. If the thickness of the resin layer 12 is 55 ⁇ m to 75 ⁇ m, there is no excess or deficiency in the corrosion resistance required for the cage for a poultry house.
