Abstract
【解決手段】 インクジェット記録ヘッド112は、ノズルプレート22、インクプールプレート24、26、スループレート28、インク供給路プレート30、圧力室プレート32、及び、振動板34を順番に積層して形成されている。これらインクジェット記録ヘッド112を構成するための各部材は、エポキシ系樹脂などの接着剤を介して互いに接着されている。インク流路120を構成する内壁122は、内壁122の全体を連続して覆う流路膜124でコーティングされている。
【選択図】 図3
Description
まず、組み立て後のインクジェット記録ヘッド112(図6(A)参照)のインク流路120の内壁122の表面を、クロム酸等を用いてエッチングし、次に、酸化チタン等のコロイドを用いてエッチング後の内壁122を活性化する(図6(B)参照)。これにより、後述する金属粒子の内壁122への密着性が高くなる。次に、インク流路120へ、金属粒子を含む金属粒子液体を充填する(充填工程、図6(C)参照)。
インクジェット記録ヘッド112が導電性の場合には、以下のようにして流路膜124を形成することができる。
次に、飽和溶解度の温度依存性を利用して、流路膜124を形成する方法について説明する。
次に、SiO2を液相成長させて流路膜124を形成する方法について説明する。
所定時間経過後、インク流路120内に残った珪フッ化水素酸溶液を排出する。インク流路120の内壁122には成長したSiO2膜が残り、これが流路膜124となる。
で囲まれた隔離室219が構成される。
