本考案はハイドロフォイルやヴアキュオフォイル方式の
抄紙機用脱水ブレードに関するものである。[Detailed Description of the Invention] The present invention relates to a dewatering blade for a hydrofoil or vacuum foil type paper machine.
抄紙機用脱水ブレードとして、性能がすぐれ寿命が長い
ためセラミック特に焼結アルミナセラミックが近年多く
用いられるようになっている。In recent years, ceramics, especially sintered alumina ceramics, have been increasingly used as dewatering blades for paper machines because of their excellent performance and long lifespan.
製紙工場の抄紙機のワイヤーパートに用いる長尺物の脱
水ブレードは例えば、第１図に示すように機械への抜き
差しを容易にする目的で、支持レールとはまり合う凹所
４（Ｔ溝）が下面に設けられた合成樹脂（ポリエチレン
、ポリエステル、ＦＲＰ等である）材料からなる基部１
を有し、表面部２にはセラミックやタングステンカーバ
イドを埋め込むがまたは、セラミックを差し込んで固定
する構造のものが一般的である。For example, a long dewatering blade used in the wire part of a paper machine in a paper mill has a recess 4 (T-groove) that fits into the support rail in order to facilitate insertion and removal into the machine, as shown in Figure 1. A base 1 made of a synthetic resin (polyethylene, polyester, FRP, etc.) material provided on the lower surface
It has a structure in which ceramic or tungsten carbide is embedded in the surface portion 2, or the ceramic is inserted and fixed.
このような従来のブレードは合成樹脂材料の基部１の剛
性が小さいため、抄紙機へブレードを取り付けるときに
たわむことにより、表面部の継ぎ目３に段差やすき間を
生じ、その上を走る紙にすしが入ったりして均一な紙が
出来ない。In such conventional blades, the base 1 made of synthetic resin material has low rigidity, so when the blade is attached to the paper machine, it flexes, creating a step or gap at the seam 3 on the surface, and the paper running over it sushi. The paper may not be uniform because of the presence of particles.
そこで第２図に示すようなセラミック材料からなる表面
部２、合成樹脂材料からなり、支持レールとはまり合う
凹所４が下面に設けられた基部１とからなり、表面部２

たせてブレードのたわみを少なくしたものが考案された
。Therefore, as shown in FIG. 2, the surface part 2 is made of a ceramic material, a base part 1 is made of a synthetic resin material, and has a recess 4 on its lower surface that fits into the support rail.
has a protrusion 6 on the lower surface with a groove 7 embedded in the base synthetic resin, and a reinforcing member 5 is inserted so that the head fits into the groove 7.
A blade was devised in which the blade was embedded in a synthetic resin material to provide rigidity and reduce deflection of the blade.
しかし補強材に鋼材を埋込むため基部の重量が鋼材の分
だけ重くなりブレードの抜き差しの作業性が悪くなると
いう欠点があった。However, since the steel material is embedded in the reinforcing material, the weight of the base increases by the amount of steel material, which has the disadvantage that the workability of inserting and removing the blade becomes poor.
本考案はかかる欠点を解消するためになされたもので、
合成樹脂材料の比重を従来のものより低くして重量の軽
いブレードを提供することを目的とする。This invention was made to eliminate such drawbacks,
The purpose is to provide a lightweight blade by lowering the specific gravity of a synthetic resin material compared to conventional ones.
本考案はセラミック材料からなる表面部および合成樹脂
材料からなる基部を有する抄紙機用脱水ブレードにおい

間の充填材を体積百分率で１０〜６５％含有してなる抄
紙機用脱水ブレードに関する。The present invention provides a dewatering blade for a paper machine having a surface portion made of a ceramic material and a base portion made of a synthetic resin material, in which a filling material for minute hollow spaces with a specific gravity of 0.9 or less is contained in the synthetic resin material of the base at a volume percentage of 10 to 10. It relates to a paper machine dewatering blade containing 65%.
なお本考案において使用される合成樹脂には制限はない
がエポキシ樹脂、不飽和ポリエステル樹脂等の熱硬化性
樹脂を使用することが好ましい。Although there are no restrictions on the synthetic resin used in the present invention, it is preferable to use thermosetting resins such as epoxy resins and unsaturated polyester resins.
また充填剤は比重が０．９以下の微小中空球であれば制
限されず、例えば日本フィライトＫＫ製のフィライト５
２／７等が使用される。In addition, the filler is not limited as long as it is a micro hollow sphere with a specific gravity of 0.9 or less; for example, Fillite 5 manufactured by Nippon Fillite KK
2/7 etc. are used.

０〜６５％含有することが必要であす、ｌ０％未満では
軽量化のために使用した効果がなく、また６５％を越え
ると通常の注型作業では行なえないため、作業が複雑に
なり、製品の特性にばらつきを生じる原因となる。The content of micro hollow spheres is 1% by volume in the base synthetic resin.
It is necessary to contain 0 to 65%. If it is less than 10%, there is no effect when using it for weight reduction, and if it exceeds 65%, it cannot be done in normal casting work, making the work complicated and reducing the quality of the product. This causes variations in the characteristics of the

40 parts by weight of a hardening agent (Ebome 1-B 002, trade name manufactured by Ajinomoto KK) were mixed, cast and cured.
この基部１中には丁字形の補強材５が、頭部が前記溝７
中に入るように埋込まれている。Inside this base 1 is a T-shaped reinforcing member 5 whose head is in the groove 7.
It is embedded so that it goes inside.
なお丁字形の補強材５は市販されていないので図示する
