Description
本発明が解決しようとする課題は、PbやCdが使用されないInベースの感熱材料であっても、スプリンクラーの作動する高い温度域のクリープ特性が良く、耐久性のあるスプリンクラーヘッドを提供することになる。
また本発明の約90〜95℃にて溶融する合金は、Zn0.05〜0.4質量%、Bi43〜55質量%、残部Inとする合金からなることを特徴とするスプリンクラーヘッドの感熱分解部分の感熱材料用合金である。
表1および表2に示したスプリンクラーヘッドの感熱分解部分の感熱材料用合金を作り、各合金組成の示差熱分析による加熱曲線を測定して吸熱ピークの開始点、吸熱ピークの最下点、吸熱ピークの終了点をもって、固相温度、ピーク温度、液相温度を測定した。表1および表2に各合金の溶融温度を示す。
表1および表2の比較例1は、特許文献1のスプリンクラーヘッドの感熱分解部分の感熱材料用合金である。
溶融温度の測定条件は次の通り。
1.示差熱分析の測定
・示差熱分析測定装置 SII製示差走査熱量計
・昇温速度:5deg/min
・試料重量:10 mg
1.) 感熱分解部分5を専用の治具に組み込み、標示温度が75℃未満のものは20℃、標示温度が75℃以上のものは最高周囲温度より20℃低い温度に設定した試験槽内に投入する。
2.) コンプレッサーで、通常の13倍の加重を240時間感熱分解部分に掛け続け、感熱分解部分の厚みがどれだけ変化したか測定する。
1.) スプリンクラーヘッドをコンプレッサーに接続して、2.5MPaの圧力を掛ける。
2.) コンプレッサーに接続したスプリンクラーヘッドを水槽中に投入して、水槽の水を加熱する。
3.) 水槽中のスプリンクラーヘッドから一気に空気が抜けた温度を作動温度として測定する。

Claims (3)
- 圧縮型の感熱分解部分に低融点合金を用いたスプリンクラーヘッドにおいて、Sn0.1〜2.0質量%、Bi31〜37質量%、残部Inとする低融点合金を感熱分解部分の感熱材料とするスプリンクラーヘッド。
- 前記感熱材料に、さらにCu0.1〜1.0質量%、Sb0.2〜2.0質量%、Ge0.1〜1.0質量%、Ag0.1〜0.7質量%、Au0.1〜0.6質量%、Zn0.2〜0.6質量%、Ni0.02 〜 0.1 質量%、La族0.01〜0.1質量%の強度添加元素の中で最低でも1元素以上を合計2.0質量%以下添加したものからなる請求項1に記載のスプリンクラーヘッド用の感熱分解部分の感熱材料とするスプリンクラーヘッド。
- 請求項1または2に記載の感熱材料を用いた作動温度が70〜75℃であるスプリンクラーヘッド。
