Description

鶏舎ケージ用格子部材の製造方法及び格子部材Method for manufacturing lattice member for poultry house cage and lattice member
　本発明は、鶏舎のケージを形成するために使用される格子部材の製造方法、及び、該製造方法により製造される格子部材に関するものである。 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.
　養鶏施設では、複数の鶏を収容するケージを水平方向に連設したケージ列を、垂直方向に複数段積み重ねたレイヤーシステムの鶏舎が多く採用されている。個々のケージは、線条材を縦横に組み付けた格子部材を使用して形成されている。線条材としては、一般的に、低炭素鋼（軟鋼）など鉄鋼で形成されたワイヤが用いられている。 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. As the wire rod, a wire formed of steel such as low carbon steel (soft steel) is generally used.
　ケージは鶏の排泄物に常に曝されている。そして、清潔な状態に保つために、ケージは大量の水で洗浄され、消毒薬が散布される。そのため、鉄鋼ワイヤで形成されているケージは、排泄物に含まれる成分、消毒薬、水分によって腐食してしまうおそれがある。 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.
　鉄鋼製品の耐食性を高めるために、亜鉛めっきを施すことが一般的になされている。しかしながら、亜鉛めっきの防食作用は、亜鉛の方が鉄よりもイオン化傾向が高いため、表層（めっき層）に含まれる亜鉛が主材の鉄に先んじて溶出することにより、主材の腐食を抑制するというものである。そのため、めっき層から溶出する亜鉛が鶏や卵に影響を及ぼすのではと懸念されていた。 In order to improve the corrosion resistance of steel products, galvanization is generally performed. However, 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.
　そこで、本発明は、上記の実情を鑑み、耐食性が高められていると共に鶏や卵に及ぼす影響が低減されている鶏舎ケージ用格子部材の製造方法、及び該製造方法により製造される格子部材の提供を、課題とするものである。 Therefore, in view of the above circumstances, 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.
　上記の課題を解決するため、本発明にかかる鶏舎ケージ用格子部材の製造方法（以下、単に「製造方法」と称することがある）は、
「鉄鋼ワイヤに溶融亜鉛－アルミニウムめっきを施し縦横に交差させて溶接することにより格子構造とした後、または、鉄鋼ワイヤを縦横に交差させて溶接することにより格子構造とし溶融亜鉛－アルミニウムめっきを施した後、樹脂で被覆する」ものである。 In order to solve the above problem, 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 ".
　本製造方法により、次の構成の鶏舎ケージ用格子部材（以下、単に「格子部材」と称することがある）が製造される。すなわち、
「亜鉛－アルミニウム合金層で被覆された鉄鋼ワイヤが縦横に交差している格子構造体、または、縦横に交差している鉄鋼ワイヤが亜鉛－アルミニウム合金層で被覆された格子構造体が、交差部を含めて最外層として樹脂層を有している」格子部材である。 By this manufacturing method, 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.
　仮に、溶融亜鉛－アルミニウムめっきを施した鉄鋼ワイヤを、更に樹脂で被覆した後で、縦横に交差させて溶接することにより格子構造とした場合、交差部は溶接による金属層を最外層として有することとなる。そのため、交差部の金属層の腐食により格子構造が崩壊するおそれや、交差部の腐食に始まって格子部材全体に腐食が広がるおそれがある。これに対し、本製造方法では、格子構造とした後で樹脂によって被覆するため、製造された格子部材は、交差部を含む全ての部分で最外層に樹脂層を有している。従って、格子部材の腐食が、樹脂層によって効果的に抑制される。 If a steel wire coated with hot-dip zinc-aluminum plating is further covered with resin and then crossed vertically and horizontally to form a lattice structure, 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. On the other hand, in this manufacturing method, 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.
　そして、格子部材により形成された鶏舎ケージの使用に伴い、最外層の樹脂層に万一亀裂が生じたり部分的に剥離したりしたとしても、その下に亜鉛－アルミニウム合金層を有している。亜鉛－アルミニウム合金層では、亜鉛が鉄鋼ワイヤの鉄の腐食を抑制するのに加えて、アルミニウムが不活性な薄膜（不動態膜）を形成する。従って、亜鉛－アルミニウム合金層を有することにより、亜鉛の溶出を抑制しながら、鉄鋼ワイヤの耐食性が高められている。しかも、部分的に樹脂層に亀裂や剥離が生じたとしても、他のほとんどの部分では、亜鉛－アルミニウム合金層の上に樹脂層を有しているため、亜鉛が溶出するおそれは極めて小さい。 With the use of 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. . In 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. Moreover, even if 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.
　以上のように、本製造方法で製造される格子部材は、樹脂層と亜鉛－アルミニウム合金層という二つのバリアを有しており、且つ、樹脂層が最外層であることにより、鶏や卵に及ぼす影響が懸念される亜鉛の溶出が抑制されていると共に、高い耐食性を有している。 As described above, 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.
　なお、鉄鋼ワイヤにめっきを施した後で溶接により格子構造とする場合（以下、「後加工」と称することがある）と、鉄鋼ワイヤを溶接により格子構造とした後でめっきを施す場合（以下、「前加工」と称することがある）との比較では、出願人の検討により、次のような知見を得ている。すなわち、前加工の方が溶接による鉄鋼ワイヤ同士の接着性が高く、格子部材の機械的強度が高い傾向がある。一方、後加工の方が、溶融めっきの際に被加工体が浴に浸漬された状態が安定し、均一なめっき層が形成される傾向がある。 It should be noted that when a steel wire is plated and then a lattice structure is formed by welding (hereinafter sometimes referred to as “post-processing”), and when a steel wire is made a lattice structure by welding (hereinafter referred to as “lattice structure”) In some cases, the following knowledge has been obtained by the applicant's examination. That is, the pre-processing tends to have higher adhesion between steel wires by welding and higher mechanical strength of the lattice members. On the other hand, post-processing tends to stabilize the state in which the workpiece is immersed in a bath during hot-dip plating, and form a uniform plating layer.
　本発明にかかる鶏舎ケージ用格子部材の製造方法は、上記構成において、
「樹脂はポリブチレンテレフタレートであり、流動浸漬塗装法により被覆される」ものとすることができる。 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”.
　ポリブチレンテレフタレートは吸水率が小さいため、大量の水で洗浄される鶏舎ケージ用の部材における最外層の材料として適している。また、ポリブチレンテレフタレートは薬品や有機溶剤に対する耐性も高いため、消毒液が散布される鶏舎ケージ用の部材における最外層の材料として適している。更に、ポリブチレンテレフタレートは耐摩耗性が高いため、鶏のくちばしや爪に接触する機会の多い鶏舎ケージ用の部材における最外層の材料として適している。 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.
　加えて、ワイヤの状態で樹脂を被覆する場合は、ワイヤと同心に樹脂を押し出して被覆するという一般的な方法を採り得るのに対し、格子構造とした後に樹脂で被覆する本発明では、このような方法は不可能である。これに対し、ポリブチレンテレフタレートは流動性が高いため、流動浸漬塗装法を採用して均一な被膜を形成することができ、格子構造とした後に樹脂で被覆する本発明の樹脂として適している。 In addition, when the resin is coated in a wire state, a general method of extruding and coating the resin concentrically with the wire can be adopted, whereas in the present invention where the resin is coated after forming the lattice structure, Such a method is impossible. On the other hand, since polybutylene terephthalate has high fluidity, a uniform coating film can be formed by employing a fluid dip coating method, and is suitable as the resin of the present invention to be coated with a resin after forming a lattice structure.
　以上のように、本発明の効果として、耐食性が高められていると共に鶏や卵に及ぼす影響が低減されている鶏舎ケージ用格子部材の製造方法、及び該製造方法により製造される格子部材を、提供することができる。 As described above, as an effect of the present invention, 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.

　以下、本発明の第一実施形態及び第二実施形態の鶏舎ケージ用格子部材の製造方法、及び、それぞれの製造方法によって製造される鶏舎ケージ用格子部材１について、図１及び図２を用いて説明する。 Hereinafter, with reference to FIG. 1 and FIG. 2, a method for manufacturing a lattice member for a poultry house cage according to the first embodiment and the second embodiment of the present invention, and a lattice member 1 for a poultry house cage manufactured by each manufacturing method will be described. explain.
　第一実施形態の製造方法では、その流れを図１（ａ）に示すように、伸線Ｐ１、溶融亜鉛－アルミニウムめっきＰ２、格子構造への加工Ｐ３、樹脂による被覆Ｐ４の順に行われる。つまり、「後加工」の例である。 In the manufacturing method of the first embodiment, as shown in FIG. 1A, 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”.
　伸線Ｐ１：
　鉄鋼のロッドをダイスに通す冷間引き抜き加工により、鉄鋼ワイヤ１０とする。本実施形態では、鉄鋼のロッドとして日本工業規格（ＪＩＳ　Ｇ３５０５）に規定する低炭素鋼（軟鋼）を使用し、直径２．０ｍｍ～２．５ｍｍの鉄鋼ワイヤ１０とする。 Drawing P1:
The steel wire 10 is obtained by cold drawing by passing a steel rod through a die. In this embodiment, 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.
　溶融亜鉛－アルミニウムめっきＰ２：
　鉄鋼ワイヤ１０を前処理した後、溶融亜鉛－アルミニウムの浴に浸漬し、鉄鋼ワイヤ１０の表面をめっき層である亜鉛－アルミニウム合金層１１で被覆する。本実施形態では、詳細は後述するように、耐食性が極めて高い９０質量％亜鉛－１０質量％アルミニウムでめっきを行う。めっき層は、３０μｍ～５０μｍの厚さとすると、鶏舎用ケージに要請される耐食性に対して過不足がなく好適である。なお、前処理は、例えば、脱脂、水洗、酸洗い、水洗、フラックス処理、乾燥の順に行うことができる。 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. In this embodiment, as will be described in detail later, plating is performed with 90 mass% zinc-10 mass% aluminum, which has extremely high corrosion resistance. When the thickness of the plating layer is 30 μm to 50 μm, there is no excess or deficiency with respect to the corrosion resistance required for the cage for a poultry house. In addition, pre-processing can be performed in order of degreasing, water washing, pickling, water washing, flux processing, and drying, for example.
　格子構造への加工Ｐ３：
　鉄鋼ワイヤ１０を縦横に交差させ、交差部２０を溶接することにより格子構造体とする。溶接に際しては、鉄鋼ワイヤ１０と同一の材料を溶加材として使用することができる。 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.
　樹脂による被覆Ｐ４：
　本実施形態では、樹脂としてポリブチレンテレフタレートを使用し、流動浸漬塗装法により被覆する。具体的には、圧縮空気を送ることによりポリブチレンテレフタレートの粉末を流動させ、流動している粉末の中に、予備加熱した格子構造体を浸漬する。これにより、格子構造体がポリブチレンテレフタレートの樹脂層１２で被覆される。樹脂層１２は、５５μｍ～７５μｍの厚さとすると、鶏舎用ケージに要請される耐食性に対して過不足がなく好適である。 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 μm to 75 μm, there is no excess or deficiency in the corrosion resistance required for the cage for a poultry house.
　上記の第一実施形態の製造方法により、図２（ａ）に示すように、亜鉛－アルミニウム合金層１１で被覆された鉄鋼ワイヤ１０が縦横に交差している格子構造体が、交差部２０を含めて最外層として樹脂層１２を有している構成の鶏舎ケージ用格子部材１が製造される。交差部２０では、鉄鋼ワイヤ１０が亜鉛－アルミニウム合金層１１、溶接層１７、樹脂層１２の順に被覆されている。 With the manufacturing method of the first embodiment, as shown in FIG. 2A, the lattice structure in which the steel wires 10 covered with the zinc-aluminum alloy layer 11 intersect vertically and horizontally is In addition, the chicken house cage lattice member 1 having the resin layer 12 as the outermost layer is manufactured. At the intersection 20, the steel wire 10 is covered with the zinc-aluminum alloy layer 11, the weld layer 17, and the resin layer 12 in this order.
　次に、第二実施形態の製造方法について説明する。第一実施形態の製造方法との相違は、図１（ｂ）に示すように、溶融亜鉛－アルミニウムめっきＰ２に先立ち、格子構造への加工Ｐ３が行われる点である。すなわち、「前加工」の例であり、伸線Ｐ１、格子構造への加工Ｐ３、溶融亜鉛－アルミニウムめっきＰ２、樹脂による被覆Ｐ４の順に行われる。溶融亜鉛－アルミニウムめっきＰ２では、上記と同様の溶融亜鉛－アルミニウムの浴に格子構造体を浸漬する。 Next, the manufacturing method of the second embodiment will be described. The difference from the manufacturing method of the first embodiment is that, as shown in FIG. 1B, processing P3 into a lattice structure is performed prior to hot dip zinc-aluminum plating P2. That is, it is an example of “pre-processing”, and is performed in the order of wire drawing P1, processing P3 into a lattice structure, hot-dip galvanized aluminum plating P2, and coating P4 with resin. In the hot dip zinc-aluminum plating P2, the lattice structure is immersed in a hot dip zinc-aluminum bath similar to the above.
　第二実施形態の製造方法により、図２（ｂ）に示すように、縦横に交差している鉄鋼ワイヤ１０が亜鉛－アルミニウム合金層１１で被覆された格子構造体が、交差部２０を含めて最外層として樹脂層１２を有している構成の鶏舎ケージ用格子部材１が製造される。交差部２０では、鉄鋼ワイヤ１０が溶接層１７、亜鉛－アルミニウム合金層１１、樹脂層１２の順に被覆されている。 With the manufacturing method of the second embodiment, as shown in FIG. 2 (b), the lattice structure in which the steel wires 10 intersecting vertically and horizontally are covered with the zinc-aluminum alloy layer 11, including the intersecting portion 20. The chicken house cage lattice member 1 having the resin layer 12 as the outermost layer is manufactured. At the intersection 20, the steel wire 10 is covered with the weld layer 17, the zinc-aluminum alloy layer 11, and the resin layer 12 in this order.
　ここで、溶融亜鉛－アルミニウムめっきＰ２において、９０質量％亜鉛－１０質量％アルミニウムを使用した根拠を説明する。同一の格子構造体に、異なる組成のめっきを施した３種類の試料Ｓ１、Ｒ１、及び、Ｒ２について、重度の腐食環境下における耐食性を評価するために、塩水噴霧試験を行った。試料Ｓ１には、第一実施形態及び第二実施形態と同様に、溶融９０質量％亜鉛－１０質量％アルミニウムめっきを施した。試料Ｒ１には、溶融９５質量％亜鉛－５質量％アルミニウムめっきを施した。試料Ｒ２には、溶融１００質量％亜鉛めっきを施した。何れの試料についても、めっきの目付量は２８０ｇ／ｍ２～３００ｇ／ｍ２とした。 Here, the grounds for using 90 mass% zinc-10 mass% aluminum in the hot dip zinc-aluminum plating P2 will be described. In order to evaluate the corrosion resistance in a severe corrosive environment, three types of samples S1, R1, and R2 in which the same lattice structure was plated with different compositions were subjected to a salt spray test. Sample S1 was subjected to 90% by mass zinc-10% by mass aluminum plating in the same manner as in the first and second embodiments. Sample R1 was plated with 95% by mass zinc-5% by mass aluminum. Sample R2 was subjected to 100% by mass galvanizing. For all samples, the basis weight of plating was 280 g / m 2 to 300 g / m 2 .

Figure JPOXMLDOC01-appb-T000001
　表１に示すように、重度の腐食環境下において、試料Ｓ１は試料Ｒ１及び試料Ｒ２に比べて、極めて耐食性が高いものであった。特に、鋼板の耐食性を高めるめっきとして日本工業規格（ＪＩＳ　Ｇ３３１７）にも規定されている溶融９５質量％亜鉛－５質量％アルミニウムめっきを施した試料Ｒ１よりも、溶融９０質量％亜鉛－１０質量％アルミニウムめっきを施した本実施形態の試料Ｓ１の方が、はるかに耐食性が高かったのは興味深い。 As shown in Table 1, in a severe corrosive environment, the sample S1 had extremely high corrosion resistance compared to the sample R1 and the sample R2. In particular, 90% molten zinc and 10% by mass of zinc were applied to the sample R1, which was subjected to molten 95% by weight zinc-5% by weight aluminum plating, which is specified in the Japanese Industrial Standard (JIS G3317) as plating for improving the corrosion resistance of the steel sheet. It is interesting that the sample S1 of this embodiment to which aluminum plating is applied has much higher corrosion resistance.
　以上のように本実施形態の製造方法によれば、ポリブチレンテレフタレートの樹脂層１２と亜鉛－アルミニウム合金層１１（９０質量％亜鉛－１０質量％アルミニウム合金層）という二つのバリアを有しており、且つ、樹脂層１２が最外層であることにより、鶏や卵に及ぼす影響が懸念される亜鉛の溶出が抑制されていると共に、耐食性が高められており、鶏舎ケージ用の部材として適している格子部材１を提供することができる。 As described above, according to the manufacturing method of the present embodiment, the polybutylene terephthalate resin layer 12 and the zinc-aluminum alloy layer 11 (90 mass% zinc-10 mass% aluminum alloy layer) are provided. And, since the resin layer 12 is the outermost layer, elution of zinc, which is concerned about the influence on chickens and eggs, is suppressed, and the corrosion resistance is enhanced, which is suitable as a member for a chicken cage. The lattice member 1 can be provided.
　以上、本発明について好適な実施形態を挙げて説明したが、本発明は上記の実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々の改良及び設計の変更が可能である。 Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and various improvements and design changes can be made without departing from the scope of the present invention. It is.
