Abstract
Description
本発明による先端面付着用カーボン固形物を石英ファイバーの先端面に当てて、1.4ワットのレーザー光を短時間(例えば、3秒間)照射することにより所望の発熱を得るのに十分な量のカーボンを石英ファイバーの先端面に付着させることができることが確認された。その理由は、カーボンと一緒に配合された粉末状無機物が、レーザー光エネルギーを吸収したことによるカーボンの発熱(推定900〜2500℃)によって溶けて接着剤として石英ファイバーの端面に密着し、冷えて固まったときにカーボンを内包する。そのため、カーボンが石英ファイバーの先端面に強固に付着し、石英ファイバーの早い動きにもカーボンは脱落することなく耐え、高温を維持するために2ワットという低出力で切開可能な発熱が得られる。
二酸化ケイ素1610〜1710℃、酸化アルミニウム2055℃、酸化チタン1855℃、塩化カルシウム175℃、塩化カリウム776℃、三二酸化鉄1550℃、酸化マグネシウム2800℃、硫酸亜鉛100℃、ビスマス271℃、バリウム726℃、塩化ストロンチウム873℃、銀961℃、タルク(含水ケイ酸マグネシウム)900℃。
ワックス・ロウ類の内パラフィンワックスを使用する場合には、固形であるから、流動パラフィンを加え加温して溶解し、室温で液状のつなぎ剤とする。また、結合剤の内カルボキシビニルポリマーを使用する場合には、水との親和性が強く、不均一な組成物となるので、グリコール類(グリセリン、プロピレングリコールなど)と予め練和した組成物を得てから水を加えて均一に溶解して液状のつなぎ剤とするのが望ましい。
