Description
本発明は真珠玉及びその製造方法に係り、より詳しくは、磁石片を核としてその周囲に真珠層を形成した真珠玉及びその製造方法に関する。 The present invention relates to a pearl and a manufacturing method thereof, and more particularly to a pearl having a pearl layer formed around a magnet piece as a core and a manufacturing method thereof.
「月のしずく」「人魚の涙」とも呼ばれる美しい光沢をたたえる真珠は、古くから世界各地で宝石として珍重されてきた。
天然真珠は、貝殻成分を分泌する外套膜が、貝の体内に偶然に入りこむことで生成されるが、産生量は極めて少なく、希少価値が高い。
一方、一般に市場に出回っているもののほとんどが、養殖真珠である。これは、二枚貝の殻から球形状に削り出した核を、アコヤガイの体内に外套膜と一緒に挿入し、真珠層を形成させたものである。
真珠の養殖には、母貝を育成し、その母貝に核を入れ、核入れ手術を施した貝を養生後、沖の筏につるした籠の中で養殖し、およそ6〜8か月後に収穫して真珠を取り出す作業を行うもので、母貝の飼育から真珠の取り出しまでに通常4年を要している。
母貝に挿入される核には、母貝と同種または異種の貝の殻を加工した天然物からなる核と、貝殻成分に近い物質を混合し、球形に成形した後、焼成して人工の核とする方法が知られている(例えば、特許文献1〜4参照)。
Pearls with a beautiful luster, called "moon drops" and "mermaid tears" have long been prized as gems around the world.
Natural pearls are produced when the mantle that secretes the shell components accidentally enters the shell, but its production is extremely small and its value is high.
On the other hand, most of what is generally on the market is cultured pearls. This is a pearl layer formed by inserting a core cut out from a shell of a bivalve shell into a spherical shape together with a mantle.
For pearl culture, a mother shell is raised, a nucleus is put into the mother shell, a shell subjected to a core insertion operation is cured, and then cultured in a cage hanging on an offshore fence, about 6 to 8 months later. It is a work to harvest and extract pearls, and it usually takes 4 years from breeding mother shells to removing pearls.
The core to be inserted into the shell is mixed with a core made of a natural product that is the same or different from the shell of the shell, and a material close to the shell component. A method of using a nucleus is known (see, for example, Patent Documents 1 to 4).
もし、磁石片を核として真珠が養殖できれば、磁力を持った真珠が形成されることになる。真珠はペンダントやイヤリングのように単独で使用されることもあるが、真珠玉を直線状に連結した連珠のネックレスとして使用されることが多く、幾重にも巻かれた豪華な装飾品として使用されることも多い。こうした使用状況に中で、磁力を持った真珠は、磁力に反応する磁性を有する装身具のチェーン(又はワイヤ)と組み合わせることにより、従来にはなかった新たな装飾を可能にし、斬新な装身具の可能性を開くものとして期待される。
磁石片を核として真珠の養殖をする上で最大の障害は、錆の発生の問題である。多くの真珠貝の養殖は海水中で行われるため、磁石をそのままアコヤガイの体内に挿入すると、たちまち錆が発生して真珠層が形成されないばかりか、母貝が死滅するという問題があった。
If a pearl can be cultured with a magnet piece as a nucleus, a pearl with magnetic force will be formed. Pearls are sometimes used alone, like pendants and earrings, but are often used as necklaces with pearl beads connected in a straight line, and are used as luxurious ornaments that are wrapped in layers. There are many cases. Under such circumstances, magnetic pearls can be combined with a chain (or wire) of magnetic jewelry that responds to magnetic force, enabling new decorations that have never existed before, and the possibility of innovative jewelry. Expected to open up sex.
The biggest obstacle to the cultivation of pearls using magnet pieces as the core is the problem of rust generation. Since many pearl oysters are cultivated in seawater, inserting the magnet directly into the body of the pearl oyster has the problem that rust is generated and a nacreous layer is not formed, and the mother mussel is killed.
本発明は、上記の問題点を解決するためになされたものであって、その目的とするところは、磁力を有する真珠玉及びその製造方法を提供することにある。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a pearl having a magnetic force and a method for producing the same.

It has the effect of opening up the possibility of a novel decoration by enabling the design of new accessories that has never existed before.
本願発明の真珠玉の製造方法は、防錆措置を施した着磁前の磁石片を真珠貝の内部に挿入した後、真珠貝を養殖し、磁石片を核として真珠層を周囲に成長させることを特徴とする。
真珠玉を収穫すること目的になされる養殖には、母貝として通常アコヤガイが使用されるが、沖縄ではクロチョウガイ、奄美大島ではマベガイが母貝として使われており、海外での養殖に使用される真珠貝を合わせると極めて多くの貝が使用されている。
The method for producing a pearl ball according to the present invention is to cultivate a pearl oyster after inserting a magnet piece before magnetization which has been subjected to rust prevention measures into the pearl shell, and grow a pearl layer around the magnet piece as a nucleus. It is characterized by that.
Akoya oysters are usually used as mother shellfish for aquaculture, which is aimed at harvesting pearl balls, but black oysters are used as mother shellfish in Okinawa, and mabeai is used as mother shellfish in Amami Oshima. When the pearl shells are combined, an extremely large number of shellfish are used.
本発明では真珠を作る貝を真珠貝と称するが、基本的に真珠層を持つほとんどの貝は真珠を産することが可能である。
本願発明では、真珠貝としてアコヤガイ、アイスランドガイ、アカネアワビ、アワビ、イガイ、イケチョウガイ、イシガイ、オウムガイ、オオウネカワボタンガイ、オオベソオウムガイ、オオビワガイ、カワシンジュガイ、カラスガイ、カサガイ、ギンイロカサガイ、クロチョウガイ、サヤガタドイツマイマイ、サラサバテイ、シシリアタイラギ、シラナミガイ、シロチョウガイ、ダイオウイトマキボラ、ダイオウショウジョウガイ、タカラガイ、タマキビ、トゲコブシボラ、ネッタイザルガイ、ハルカゼヤシガイ、ヒラツバサカワボタンガイ、ピンクガイ、ブローデリップヤシガイ、ベニコチョウガイ、ボタンガイ、ホンビノスガイ、ホシダカラ、マイマイ、マベガイ、マルスダレガイ、マゼランツキヒガイ、ヤコウガイ、ヨーロッパイガイ、ヨーロッパタマキビ、及びヨーロッパヒラガキを例示することができる。本発明ではこれらの群から選択される一つ又は複数を真珠貝とすることができる。
In the present invention, shells for producing pearls are referred to as pearl shells, but most shells having a pearl layer can basically produce pearls.

真珠の養殖には、これらの母貝を育成し、その母貝の内部に真珠玉の核となる真珠核を挿入し、挿核手術を施した貝を一定期間養生後、母貝の生育に適した環境下で、例えば沖の筏につるした籠の中で養殖すればよい。養殖期間は母貝の生育に合わせ、半年から1年継続すればよい。アコヤガイの場合、挿核手術から6〜8か月で収穫することができる。
本願発明は、母貝に挿入する核を、防錆措置を施した着磁前の磁石片としたところに特徴がある。母貝に挿入される着磁前の磁石片としては、着磁後にフェライト磁石、サマリウムコバルト磁石、及び、ネオジウム磁石となる成分構成の磁石片の群より選ばれた一種であることが好ましい。
フェライト磁石は酸化鉄を主原料にして成形し焼き固めて作ることができる。サマリウムコバルト磁石はサマリウムとコバルトを原料として成形し焼き固めて作ることができる。ネオジウム磁石はネオジム、鉄、ホウ素を主成分として成形し焼き固めて作ることができる。
本願発明ではこれらの磁石の何れも好ましく使用することができる。
いずれの磁石も自由な形状に成形することができる。本願発明の真珠玉は、磁石片の形状を自由な形状(例えば、ハート形、星形等)にすることができることから、様々な形状の真珠玉を生産することができ、その装飾方法も従来とは異なる状態で装飾できることから、全く新しい装身具のデザインを提供することができる。
For pearl culture, these mother shells are raised, the pearl nucleus that is the core of the pearl is inserted into the mother shell, and the shells that have undergone nucleation surgery are cured for a certain period of time before the mother shell grows. It may be cultivated in a suitable environment, for example, in a cage hung off the coast. The culture period may be continued from half a year to one year according to the growth of the mother shellfish. In the case of the pearl oyster, it can be harvested in 6 to 8 months after the operation.
The present invention is characterized in that the core to be inserted into the mother shell is a magnet piece before magnetization subjected to rust prevention measures. The magnet piece before magnetization inserted into the mother shell is preferably one kind selected from the group of component magnet pieces that become ferrite magnets, samarium cobalt magnets, and neodymium magnets after magnetization.
Ferrite magnets can be made by molding, baking, and hardening using iron oxide as the main raw material. Samarium-cobalt magnets can be made by molding and baking from samarium and cobalt. Neodymium magnets can be made by molding, baking and solidifying with neodymium, iron and boron as the main components.
In the present invention, any of these magnets can be preferably used.
Any magnet can be formed into a free shape. Since the pearl of the present invention can make the shape of the magnet pieces free (for example, a heart shape, a star shape, etc.), pearl balls of various shapes can be produced, and the decoration method is also conventional. Since it can be decorated in a different state, it is possible to provide an entirely new accessory design.
着磁前の磁石を真珠核として使用する際の最大の問題は核となる磁石片に錆が発生することにある。特に真珠貝は水棲であり、多くの場合、汽水域から海水域で生育することから、真珠貝の内部に挿入された磁石片も、これらの塩水に曝されるため、たちまち錆が発生することになる。
核に錆が発生すると、真珠層が形成されないばかりか、溶出した金属イオンにより母貝が死滅する虞がある。また仮に、真珠層が形成されたとしても、磁石の表面は変色し、装飾に耐えられる真珠玉は生産されない。
磁石片の防錆方法としては、磁石片をめっきする方法と、磁石片を樹脂コーティングする方法がある。
めっきは酸化しやすい金属を、酸化されにくい金属で覆うもので、古くから利用されている技術である。めっきの方法としては、電気めっき、クロムめっき、無電解めっき、溶融めっき、真空蒸着、不溶解性アノード及び電鋳等が知られているが、本発明ではこれらの何れの方法も利用可能であり、状況に合わせてその一つ以上を選択することができる。
The biggest problem when using a magnet before magnetization as a pearl nucleus is that rust is generated on a magnet piece as a nucleus. In particular, pearl oysters are water tanks and often grow in brackish water to sea water, so magnet pieces inserted inside pearl oysters are also exposed to these salt waters, so rust is generated immediately. become.
When rust is generated in the nucleus, not only the nacreous layer is not formed, but also the mother shellfish may be killed by the eluted metal ions. Even if a pearl layer is formed, the surface of the magnet changes color and pearls that can withstand decoration are not produced.
As a rust prevention method for the magnet piece, there are a method of plating the magnet piece and a method of resin coating the magnet piece.
Plating is a technique that has been used for a long time, covering easily oxidizable metal with metal that is not easily oxidized. As plating methods, electroplating, chromium plating, electroless plating, hot dipping, vacuum deposition, insoluble anode, electroforming, etc. are known, but any of these methods can be used in the present invention. , You can select one or more according to the situation.
めっきされる金属としては、金、銀、銅、白金、スズ、クロム、ニッケル、及びこれらの合金からなる群より選ばれた一種以上であることが好ましい。
これらの金属をめっきされた磁石片は、金属光沢を表面に備えることになる。例えば、シアン化カリウムを電解質として電気めっきにより金をめっきした磁石片の表面は金色に輝き、銅めっきした磁石片は銅色に、また、銀、白金、スズ、クロム、ニッケルをめっきした磁石片は銀色の金属光沢を備える。
これらの金属光沢を有する磁石片を真珠貝の内部に挿し入れ、磁石片を核として真珠層を周囲に成長させると、金属光沢を有する磁石片の表面に真珠層が形成され、輝きを保ちながらも、ギラギラした輝きが抑えられた上品な(または、優雅な、奥ゆかしい)感触の真珠玉を生産することができる。
The metal to be plated is preferably one or more selected from the group consisting of gold, silver, copper, platinum, tin, chromium, nickel, and alloys thereof.
The magnet pieces plated with these metals have a metallic luster on the surface. For example, the surface of a magnet piece plated with gold by electroplating with potassium cyanide as an electrolyte shines in gold, the copper piece with copper plating becomes copper, and the piece with silver, platinum, tin, chromium, nickel is silver With a metallic luster.
When these metallic luster magnet pieces are inserted into the inside of the pearl shell and the nacreous layer is grown around the magnet pieces as a core, a nacreous layer is formed on the surface of the metallic luster magnet pieces, while maintaining shine. However, it is possible to produce pearls with a refined (or elegant, graceful) feel with reduced glare.
他の磁石片の防錆方法としては、磁石片を樹脂コーティングする方法がある。樹脂コーティング方法としては、従来から利用されている、スプレー方法、ペイント方法、フィルムラップ方法、浸漬方法、インサートインジェクション方法などの何れの方法であってもよい。
磁石片にコーティングできる樹脂としては、ポリエチレン、ポリプロピレン、ポリスチレン、アクリル樹脂、メタクリル樹脂、AS樹脂、ABS樹脂、ポリウレタン樹脂、ポリ塩化ビニル樹脂等の汎用プラスチック、ポリアミド6、ポリアミド66、ポリカーボネート、ポリアセタール、ポリエチレンテレフタレート、ポリブチレンテレフタレート、変性ポリフェニレンエーテル等の汎用エンジニアリングプラスチック、ポリアリレート、ポリスルホン、ポリエーテルスルホン、ポリアミドイミド、ポリエーテルイミド、ポリフェニレンスルフィド、ポリエーテルエーテルケトン、ポリイミド、フッ素樹脂等のスーパーエンジニアリングプラスチックを挙げることができる。
また、磁石片にコーティングされる樹脂が、フェノール樹脂、尿素樹脂、メラミン樹脂、エポキシ樹脂、シリコン樹脂、不飽和ポリエステル、及び、ポリウレタン、等の熱硬化性樹脂であってもよい。
中でも、ポリエチレン、ポリプロピレン、ポリスチレン、メタクリル樹脂等の汎用プラスチック、及び、ポリアミド6、ポリアミド66、ポリカーボネート、ポリアセタール、ポリエチレンテレフタレート等の汎用エンジニアリングプラスチックは好ましく使用することができる。
着磁されていない磁石片をコーティングする樹脂以外のものとして柿渋、漆、黄檗、又は琥珀等の天然ポリマーを使用することもできる。
As another rust prevention method for the magnet piece, there is a method of resin coating the magnet piece. The resin coating method may be any method conventionally used, such as a spray method, a paint method, a film wrap method, a dipping method, or an insert injection method.
The resin that can be coated on the magnet piece is a general-purpose plastic such as polyethylene, polypropylene, polystyrene, acrylic resin, methacrylic resin, AS resin, ABS resin, polyurethane resin, polyvinyl chloride resin, polyamide 6, polyamide 66, polycarbonate, polyacetal, polyethylene. General engineering plastics such as terephthalate, polybutylene terephthalate, modified polyphenylene ether, and super engineering plastics such as polyarylate, polysulfone, polyethersulfone, polyamideimide, polyetherimide, polyphenylene sulfide, polyetheretherketone, polyimide, and fluororesin be able to.
The resin coated on the magnet piece may be a thermosetting resin such as phenol resin, urea resin, melamine resin, epoxy resin, silicon resin, unsaturated polyester, and polyurethane.
Among these, general-purpose plastics such as polyethylene, polypropylene, polystyrene, and methacrylic resin, and general-purpose engineering plastics such as polyamide 6, polyamide 66, polycarbonate, polyacetal, and polyethylene terephthalate can be preferably used.
Natural polymers such as persimmon astringent, lacquer, yellow persimmon, or persimmon can also be used as a material other than the resin for coating the magnet pieces that are not magnetized.
めっきされた着磁前の磁石片を上記の樹脂でさらにコーティングすることもできる。めっきされた磁石片をさらに樹脂コーティングすることにより、金属光沢をもった表面の退色(変色)を防止することができる。
また、上記樹脂がコーティイングされた着磁前の磁石片の表面にさらに別の種類の樹脂またはフィラーを含む樹脂でコーティングすることもできる。
樹脂を二重にコーティングする場合、外側のコーティングには、親水性の樹脂を使用することができる。
本発明では、親水性の樹脂としてポリビニルアルコール、ポリエチレングリコール、ポリビニル酢酸樹脂及びポリアクリル酸ナトリウム等を挙げることができる。中でもポリエチレングリコールは好ましく利用することができる。
真珠貝の内部に挿入される核の表面を親水性の樹脂で覆うことにより、真珠貝の内部に留まる核の割合が向上し、真珠層が形成されやすくなることから、真珠玉の収穫量を向上させることができる。
The plated magnet pieces before magnetization can be further coated with the above resin. By further coating the plated magnet pieces with a resin, fading (discoloration) of the surface with metallic luster can be prevented.
Further, the surface of the magnet piece coated with the resin before magnetization can be coated with another type of resin or a resin containing a filler.
When the resin is coated twice, a hydrophilic resin can be used for the outer coating.
In the present invention, examples of the hydrophilic resin include polyvinyl alcohol, polyethylene glycol, polyvinyl acetate resin, and sodium polyacrylate. Among these, polyethylene glycol can be preferably used.
Covering the surface of the core inserted into the pearl shell with a hydrophilic resin increases the percentage of the core that stays inside the pearl shell and facilitates the formation of a pearl layer. Can be improved.
樹脂がコーティイングされた着磁前の磁石片の表面にフィラーを含む樹脂をさらにコーティングすることもできる。
本発明では外側にコーティングされる樹脂に混錬されるフィラーとして、炭酸カルシウム、リン酸カルシウム等の貝殻成分、アパタイト、タルク、シリカ、クレー等の天然鉱石、酸化チタン、アルミ粉、ガラスビーズ、マイカ、ジルコニア等の光散乱剤が挙げられる。中でも炭酸カルシウムは、真珠貝内部に留まる核の割合を向上させるばかりでなく、真珠層が形成された真珠玉の透明性を増すことができることから好ましく利用することができる。
外側にコーティングされる樹脂に塗料を混合してもよい。様々な色の塗料を混合することで、従来は存在しなかった色調の真珠玉を生産することができる。
真球の真珠玉を目的にする場合、めっきまたは樹脂がコーティングされた着磁前の磁石片は円盤と混合砂を使用して真球の核に仕上げることが好ましい。
It is also possible to further coat a resin containing a filler on the surface of the magnet piece coated with the resin before magnetization.
In the present invention, as fillers kneaded in the resin coated on the outside, shell components such as calcium carbonate and calcium phosphate, natural ores such as apatite, talc, silica, clay, titanium oxide, aluminum powder, glass beads, mica, zirconia And the like. Among these, calcium carbonate can be preferably used because it not only improves the proportion of nuclei staying inside the pearl shell, but also increases the transparency of the pearl balls on which the pearl layer is formed.
A paint may be mixed with the resin coated on the outside. By mixing paints of various colors, it is possible to produce a pearl with a color that did not exist before.
When a pearl of a true sphere is intended, it is preferable that the magnetized piece before plating or coating with resin is finished into a sphere core using a disk and mixed sand.
防錆措置を施した着磁前の磁石片は、核入れ手術により真珠貝の内部に挿入され、自然環境の中で養殖されるが、この過程は、養殖真珠の生産過程と同一であるためその説明を省略する。
さらに、一定期間の養殖の後に、浜揚げにより真珠を取り出し、選別する工程も、養殖真珠の生産過程と同一であるためその説明を省略する。
選別された真珠層が形成された着磁前の磁石片は、真珠層及び磁石片を貫通する孔開け加工を行い、その中心に貫通孔が形成される。
貫通孔が形成された真珠層を有する着磁前の磁石片は、強力な磁場に中に曝すことにより着磁することができる。
The magnetized pieces that have been rust-prevented are inserted into the pearl shells by nuclear surgery and cultured in the natural environment, but this process is the same as the production process of cultured pearls. The description is omitted.
Furthermore, since the process of taking out and selecting pearls by raising the beach after a certain period of culture is the same as the production process of cultured pearls, the description thereof is omitted.
The magnet piece before magnetization, on which the selected pearl layer is formed, is perforated through the pearl layer and the magnet piece, and a through hole is formed at the center thereof.
An unmagnetized magnet piece having a nacreous layer with through holes formed therein can be magnetized by exposing it to a strong magnetic field.
着磁の方法は、作成する磁極の数により決定されるが、本発明の場合には着磁コイルによる着磁が適当である。着磁コイルによる着磁は、大容量のコンデンサーに充電した電荷を瞬間的に放電するコンデンサー式着磁電源装置(パルス式電源)を 使用し、着磁コイル、ヨークに大電流を通電すると、着磁コイルの長さ方向に沿った一方向に磁界が生じ着磁コイルの中に設置した磁石片は、一対のN極、S極を有する磁石に着磁される。
このとき、着磁コイル内に設置した着磁前の磁石片の向きにより、N極とS極の位置が決定される。通常、着磁前の磁石片に開けられた貫通孔は着磁コイルの径方向と重なるように設置し、着磁後に貫通孔が赤道を貫通するようにすることが好ましい。
仮に、貫通孔がN極とS極を貫通するように着磁させると、1本の装身具チェーンに複数の真珠玉を連珠したとき、真珠玉同士が引き合うか又は反発しあって、思いどおりの装飾ができなくなる虞がある。貫通孔が赤道を貫通するようにすると、磁力により真珠玉同士が引き合ったり、反発しあったりしても、装身具チェーンを中心に真珠玉が回転することで、この磁界の歪を解消することができる。
The magnetization method is determined by the number of magnetic poles to be created. In the present invention, magnetization by a magnetizing coil is appropriate. Magnetization by a magnetizing coil is performed by using a capacitor-type magnetizing power supply (pulse-type power supply) that instantaneously discharges the charge stored in a large-capacity capacitor. A magnetic field is generated in one direction along the length direction of the magnetic coil, and the magnet piece installed in the magnetizing coil is magnetized by a magnet having a pair of N poles and S poles.
At this time, the positions of the N pole and the S pole are determined by the orientation of the magnet pieces before magnetization installed in the magnetizing coil. Usually, it is preferable that the through hole opened in the magnet piece before magnetization is installed so as to overlap with the radial direction of the magnetized coil, and the through hole penetrates the equator after magnetization.
If the through-hole is magnetized so as to penetrate the N and S poles, when a plurality of pearl balls are connected to a single accessory chain, the pearl balls attract each other or repel each other. There is a possibility that the decoration cannot be performed. By making the through hole penetrate the equator, even if the pearls are attracted or repelled by the magnetic force, the pearls rotate around the jewelry chain, and this distortion of the magnetic field can be eliminated. it can.

〔比較例1:二枚貝の殻から製造した核を真珠貝へ挿入〕
上記実施例2〜6の磁石片の代わりに米国ミシシッピー川に生息しているイシガイ科の二枚貝の殻を研磨加工した直径6mmの真球形状の核の100個をアコヤガイの内部に挿入した。実施例2〜6と同様に8か月間、沖に浮かべた筏につるした籠の中で養殖した。8か月後に浜揚げ(収穫)を行い、母貝の生存率、真珠玉の回収率、真珠玉の品質を検査した。
[Comparative Example 1: Inserting a core manufactured from a bivalve shell into a pearl shell]
Instead of the magnet pieces of Examples 2 to 6, 100 sphere-shaped nuclei having a diameter of 6 mm obtained by polishing shells of clams from the Mississippi River in the United States were inserted into the pearl oyster. As in Examples 2-6, the animals were cultivated in a cage hanging on a shore floating off the coast for 8 months. Eight months later, the beach was picked (harvested), and the survival rate of mother shellfish, the recovery rate of pearls, and the quality of pearls were examined.
実施例2〜6及び比較例1の検査の結果を表1に示した。
母貝生存率は8か月、沖の筏につるした籠の中に生息していた母貝の数を計測し養殖当初の母貝の数を基に計算した。真珠玉回収率は、浜揚げ後に回収した真珠玉の数を養殖当初の母貝の数で除して計算した。母貝生存率と真珠玉回収率との差は養殖過程で核が脱落した母貝の割合に相当する。
真珠玉の品質は、色・形・キズなどで選別し、「輝き」「色」「巻き」の優れた真珠に相当するものを「優」、一連の連珠ネックレスに加工できる程度の品質のものを「良」、複数の列の連珠ネックレスに加工される程度の品質のものを「可」、加工しても商品にならないものを「不可」として計測し、養殖当初の母貝の数で除して計算した。ただし、「優」の評価については、比較例1は「輝き」「色」「巻き」の総合評価とし、実施例2〜6は「輝き」「色」「巻き」のうち一つの項目でも秀でたものは「優」と判定した。
The survival rate of mother shellfish was calculated based on the number of mother shellfish at the beginning of aquaculture by measuring the number of mother shellfish that lived in the cage hanging off the coast of Okinawa for 8 months. The pearl recovery rate was calculated by dividing the number of pearls recovered after beaching by the number of mother shellfish at the beginning of the cultivation. The difference between the survival rate of mother shellfish and the recovery rate of pearls corresponds to the proportion of mother shellfish whose nuclei have fallen during the aquaculture process.
The quality of pearls is selected by color, shape, scratch, etc., and the quality corresponding to pearls with excellent “shine”, “color” and “winding” is “excellent”, and can be processed into a series of chain necklaces. Measured as “good”, quality that can be processed into multiple rows of pearl necklaces as “good”, and those that do not become a product even if processed, as “impossible”, and divided by the number of mother shellfish at the beginning of the cultivation And calculated. However, regarding the evaluation of “excellent”, Comparative Example 1 is a comprehensive evaluation of “shine”, “color”, and “winding”, and Examples 2 to 6 are excellent even in one item of “shine”, “color”, “winding”. What was out was judged as “excellent”.
表1に示したとおり、実施例2〜6の母貝生存率は29〜43%と、比較例1の60%に比べて低い値であり、真珠玉回収率も17〜38%と比較例1の55%に比べて低い値であった。これは、100年の実績のある真珠養殖に対して、防錆処置した磁石片を核とする真珠養殖では、未だ最適な養殖条件が把握できていないためであると思われる。
ニッケルめっきしたネオジウム磁石片を核として養殖した実施例2は、母貝生存率が低く、品質でも不良品の割合も高かった。これはニッケルメッキだけで錆の発生を抑えることが難しく、溶出した金属イオンが母貝に悪影響を及ぼしていることが考えられる。品質不良も核の変色によるものが多かった。
めっき加工したネオジウム磁石片の表面にアクリル樹脂をコーティングした磁石片を核とした実施例3では、実施例2で見られた核の変色や母貝生存率の問題が改善され、母貝生存率は29から31%に、真珠玉回収率は17から23%に向上した。真珠玉の品質では「優」の割合が高くなった。これはめっきされた金属の変色が抑えられると、金属光沢が維持され、これを真珠層を通して見ることができるため、優美さを感じさせるものになったためである。
As shown in Table 1, the survival rate of mother shellfish in Examples 2 to 6 is 29 to 43%, which is a lower value than that of Comparative Example 1, and the recovery rate of pearl beads is also 17 to 38%, which is a comparative example. The value was lower than 55% of 1. This seems to be because the optimal aquaculture conditions have not yet been grasped in pearl farming with rust-proof magnet pieces as the core, compared to pearl farming with a track record of 100 years.
In Example 2, which was cultured using a nickel-plated neodymium magnet piece as a core, the survival rate of the mother shellfish was low, and the ratio of defective products was high in terms of quality. This is because it is difficult to suppress the generation of rust only by nickel plating, and it is considered that the eluted metal ions have an adverse effect on the mother shellfish. Many of the poor quality were due to discoloration of the nucleus.
In Example 3 in which the surface of the plated neodymium magnet piece was coated with an acrylic resin-coated magnet piece, the problems of the core discoloration and the shellfish survival rate observed in Example 2 were improved, and the shellfish survival rate was improved. Improved from 29 to 31% and the pearl recovery rate from 17 to 23%. The percentage of “excellent” increased in the quality of pearls. This is because when the discoloration of the plated metal is suppressed, the metallic luster is maintained, and this can be seen through the nacreous layer, which makes it feel elegant.
ポリエチレンでコーティングした磁石片を核とした実施例4では、母貝の生存率が向上したにもかかわらず、真珠玉の回収率が向上しなかった。これはポリエチレンの表面が平坦で引っかかりがないことから、母貝からの核の脱落が多く発生したと考えられた。これはポリエチレンの表面に真珠層が正常に形成されなかった不良品が多いことからも裏付けられた。
ポリエチレンをコーティングしたネオジウム磁石片の表面をポリエチレングリコールでさらにコーティングした磁石片を核とした実施例5は、母貝生存率が42%に、真珠玉回収率が38%に向上した。これはポリエチレングリコールが親水性であるため母貝との親和性が向上したためと考えられる。
ポリエチレンをコーティングしたネオジウム磁石片の表面を炭酸カルシウムのフィラーを含有する塩化ビニル樹脂でコーティングした磁石片を核とした実施例6は、母貝生存率が43%と高かったが、真珠玉回収率は34%に留まった。これは炭酸カルシウムが貝殻の成分であることから、母貝が核を異物と認識しにくかったものと考えられる。実施例6は品質評価で「優」の割合が最も高かった。これは樹脂に炭酸カルシウムのフィラーを配合することにより透明性が向上し、透明感のある真珠玉が産生されたためである。
In Example 4 using a polyethylene-coated magnet piece as a core, the recovery rate of pearls was not improved, although the survival rate of mother shellfish was improved. This was thought to be due to the loss of the core from the mother shell because the polyethylene surface was flat and not caught. This was supported by the fact that there were many defective products in which the pearl layer was not normally formed on the polyethylene surface.
In Example 5 in which the surface of the polyethylene-coated neodymium magnet piece was further coated with polyethylene glycol as a core, the shellfish survival rate improved to 42% and the pearl recovery rate improved to 38%. This is thought to be due to the improved affinity with the mother shell because polyethylene glycol is hydrophilic.
In Example 6 in which the surface of the polyethylene-coated neodymium magnet piece was coated with a vinyl chloride resin containing a calcium carbonate filler as a core, the survival rate of mother shellfish was as high as 43%. Remained at 34%. This is probably because calcium carbonate is a component of the shell, and it was difficult for the mother shell to recognize the nucleus as a foreign object. In Example 6, the ratio of “excellent” was the highest in the quality evaluation. This is because transparency was improved by adding a filler of calcium carbonate to the resin, and a transparent pearl was produced.
〔実施例7:貫通孔加工と着磁〕
実施例2〜6でその品質が「優」から「可」と評価された真珠玉は、孔開け加工により、磁石片及び真珠層を貫通する孔を真珠玉の中心に設けた。貫通孔加工を完了した真珠玉はコンデンサー式着磁電源装置に連結した着磁コイルの中で着磁された。着磁に際し、貫通孔を形成した真珠玉は、着磁コイルの直径が貫通孔と一致するように設置され、10、000アンペアの電流が瞬時、着磁コイルに通電された。この着磁により真珠玉を地球に見立てたとき、貫通孔が真珠玉の赤道上にある位置で北極と南極に相当する位置にN極とS極が形成された。
着磁された真珠玉は、貫通孔に磁性を有するステンレスのワイヤが通され、磁力を有する真珠玉のデザインが検討された。磁性を有するステンレスのワイヤが通された磁力を有する真珠玉は、ワイヤの任意の位置に真珠玉を留め置くことができる画期的な能力を有するものであった。
[Example 7: Machining and magnetizing through holes]
The pearls whose quality was evaluated as “good” to “good” in Examples 2 to 6 were provided with a hole penetrating the magnet piece and the pearl layer at the center of the pearl by drilling. The pearls that completed the through hole processing were magnetized in a magnetizing coil connected to a condenser magnetizing power supply. Upon magnetization, the pearls with through holes were installed so that the diameter of the magnetized coil coincided with the through holes, and a current of 10,000 amperes was instantaneously passed through the magnetized coil. When the pearl was considered to be the earth by this magnetization, an N pole and an S pole were formed at positions corresponding to the north and south poles where the through hole was on the equator of the pearl.
A magnetized stainless steel wire was passed through the through hole of the magnetized pearl, and the design of a pearl having a magnetic force was studied. A pearl ball having a magnetic force through which a stainless steel wire having magnetism is passed has an epoch-making ability to retain the pearl ball at an arbitrary position of the wire.
