【発明の詳細な説明】
本発明はレーヨン系、アクリル系繊維紡糸ノズル用材料
として使用する合金の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in alloys used as materials for rayon-based and acrylic-based fiber spinning nozzles.
従来、上述の如きレーヨン系、アクリル系絨維紡糸ノズ
ル用材料としては金−白金（３０〜５ｏｂ）合金が多用
されている。この合金は１時効処理前は薄板、絞り、細
孔加工性が優れているが、時効処理後の耐摩耗性、耐圧
力が低い為、完成品として使用している場合、摩耗のた
め吐出孔の紡糸面側のかどが減った夕、破損したりする
という欠点があった。Conventionally, gold-platinum (30-5 ob) alloy has been widely used as a material for the above-mentioned rayon-based and acrylic-based fiber spinning nozzles. This alloy has excellent workability for thin sheets, drawing, and fine holes before aging treatment, but its wear resistance and pressure resistance after aging treatment are low. The problem was that when the edge of the spinning side of the spinning surface became thin, it could break.
本−発明は上記の欠点を解消せんが為になされたもので
あり、加工性、耐摩耗性、耐圧力に優れた紡糸ノズル用
合金を提供せんとするものである。The present invention was made in order to eliminate the above-mentioned drawbacks, and aims to provide an alloy for spinning nozzles that is excellent in processability, wear resistance, and pressure resistance.
本発明による紡糸ノズル用合金の１つは白金８０〜９８
Ｗ１０ 、ガリウム２−２０ Ｗｌｏよりなる時効硬化
性を具備したもので、もう１つは白金６５〜９５− 、
ガリウム２〜２０ ｗｌｏ、残部パラジウムよりなる時
効硬化性を具備したものである。One of the alloys for spinning nozzles according to the present invention is platinum 80-98
W10, gallium 2-20 Wlo with age hardenability, and the other one is platinum 65-95-,
It has age hardenability and is composed of 2 to 20 wlo of gallium and the balance palladium.
本発明による紡糸ノズル用合金に於いて、ガリウムを添
加した理由は白金−ガリウムの２元状態図からも明らか
なようにガリウムは白金に対して１３６１℃で最大同浴
量６Ｗ１０含示し、その固溶度は温度下降と共に漸次減
少し、固溶体領域まで加熱し、急冷する溶体化処理を行
った後、適当な温度で時効させると著しい時効硬化性′
ｆＩ：現わす為である。The reason for adding gallium to the alloy for spinning nozzles according to the present invention is that, as is clear from the binary phase diagram of platinum-gallium, gallium has a maximum bath amount of 6W10 compared to platinum at 1361°C, and its solidity The solubility gradually decreases as the temperature decreases, and after performing a solution treatment that heats to a solid solution region and rapidly cools it, it exhibits remarkable age hardening when aged at an appropriate temperature.
fI: To appear.
その添加量が２Ｗ１０未満では、硬さの改善が殆んどな
く、２０′Ｎ１０を超えると白金とガリウムの金属間化
合物の量が多くなり、加工性が悪くなるからである。ま
た、パラジウムを添加した理由はカリウムの添加による
耐酸性、耐アルカリ性の低下を防止するためである。If the amount added is less than 2W10, there is little improvement in hardness, and if it exceeds 20'N10, the amount of intermetallic compound of platinum and gallium increases, resulting in poor workability. Further, the reason for adding palladium is to prevent the acid resistance and alkali resistance from decreasing due to the addition of potassium.
以下、本発明による紡糸ノズル用合金の効果を明瞭なら
しめる為に実施例及び従来例について述べる。Examples and conventional examples will be described below in order to clarify the effects of the alloy for spinning nozzles according to the present invention.
