本発明は、ガラスファイバー用ブッシングに関するもの

、第１図に示すようにブッシング１のノズル２とプレー
ト３の周囲に溶融ガラス４が濡れてしまう。そのため、
ガラスファイバー５が断線したり、糸径が不安定になっ
たり紡糸できなくなったりするなどの欠点があった。Conventionally, as a bushing material for glass fiber, p
T, Pt-Rh alloys, or alloys in which a small amount of a high melting point oxide such as zirconia is dispersed therein have been used. However, bushings made of conventional materials have a wetting angle of molten glass of 20°C at Pt at a temperature of 1200°C.
, Pt-RhlO% alloy is as small as 30'c, so the molten glass 4 gets wet around the nozzle 2 and plate 3 of the bushing 1, as shown in FIG. Therefore,
There were drawbacks such as the glass fiber 5 being broken, the thread diameter becoming unstable, and spinning impossible.
紡糸は多量のガラス原料を投入して、数ケ月間連続して
行なわれるためこのような欠点が直接製品歩留りに影響
して不良品の選別等にむだな時間がかかっていた。Since spinning is carried out continuously for several months using a large amount of glass raw material, these defects directly affect the product yield and waste time is wasted in sorting out defective products.
本発明は上記欠点に層みなされたものであり、糸径の安
定したガラスファイバーを得ることを目的とする。The present invention addresses the above-mentioned drawbacks and aims to obtain glass fibers with a stable thread diameter.
本発明は、白金又は白金合金よりなるブッシングプレー

徴とするガラスファイバー用ブソシンダである。The present invention is a bushing cinder for glass fiber characterized in that the nozzle tip of the bushing plate made of platinum or a platinum alloy is made of an Au-Pt alloy.
本発明においてＡ１１−ｐｔ系合金を用いるのは溶融ガ
ラスに対する濡れ性を改善するためである。The purpose of using the A11-pt alloy in the present invention is to improve the wettability to molten glass.
すなわち、ΔＵをｐｔ又はｐｔ金合金添加していくと、
著しく濡れ角度が高くなる。たとえば、Ｉ）ｔの１２０
０°Ｃのガラスファイバーに対する角度は２５″である

ながら、Ａｕ−Ｐｔ系合金はＡｕが偏析しやすいため、
均質な板がつくれず、また深絞りした場合にはクラック

な板を高温にさらした場合には、不均質箇所からガラス
がもれたりする事故がおこる危険がある。そこで、Δｕ
−Ｐｔ系合金の機械的加工性を考慮して、ブッシングプ
レートのノズル先端部にＡｕ−Ｐｔ系合金を用いること
とした。ブッシングプレートとの接合は、溶接やろう付
等でよいが接合目跡がないことがより々了ましい。That is, when ΔU is added to pt or pt gold alloy,
The wetting angle becomes significantly higher. For example, I) 120 of t
The angle with respect to the glass fiber at 0°C is 25″, but when 1% Au is added, it is 45°, and when 3% Au is added, it is 60°.
If 15% is added, the angle becomes close to 80°. This phenomenon occurs in Pt-Rh alloy, Pt-Pd alloy, ZrO
The same holds true for the PT gold alloy in which the metal is dispersed. However, since Au-Pt alloys tend to segregate Au,
A homogeneous plate cannot be made, and cracks occur when deep drawing is performed, resulting in poor mechanical workability. Therefore, if a non-uniform plate is exposed to high temperatures, there is a risk that the glass may leak from the non-uniform areas. Therefore, Δu
- Considering the mechanical workability of the Pt alloy, it was decided to use an Au-Pt alloy for the nozzle tip of the bushing plate. The bushing plate may be joined to the bushing plate by welding, brazing, etc., but it is better to have no joint marks.
第２図に示すようにＡ ｕ −Ｐ を系合金よりなるノ
ズル先端部６のブッシング１′を用いてガラスファイバ

ためノズル周囲には溶融ガラスはいきづらい。また溶融
ガラスがノズル周囲に付着しても、ブッシングプレート
の方が溶融ガラスに部は清浄に保たれガラスファイバー
に影響を及ぼすことがない。As shown in Fig. 2, when the glass fiber 5 is manufactured using the bushing 1' of the nozzle tip 6 made of A u -P based alloy, the molten glass does not flow around the nozzle because the wetting angle with respect to the glass is large. It's difficult. Furthermore, even if molten glass adheres to the area around the nozzle, the bushing plate keeps the molten glass area clean and does not affect the glass fibers.
以下、実施例および従来例について説明する。Examples and conventional examples will be described below.

スが付着してぃなかった。Using 5 bushings made of PT with 400 nozzles made of 5% PL-Au alloy with a discharge hole of 2 mm φ, heated to +200'C by the direct method and operated continuously for 6 months, the glass fiber was heated. Created. When I stopped operation after 6 shots, there was almost no glass attached to the nozzle plate surface.
ｐｔよりなるノズル以外実施例と同様にして連続運転し
たところ４ケ月目で糸がひけなくなってしまった。４ケ
月後に運転をやめたところノズルプレート面にガラスが
付着していた。When continuous operation was performed in the same manner as in the example except for the nozzle made of PT, the yarn could no longer be drawn after 4 months. When I stopped operation after 4 months, I found that glass had adhered to the nozzle plate surface.
