hydracidとは 意味・読み方・使い方

At first, the content of lead in the internal surface of a hollow building material is reduced by a treatment with a reducing aqueous solution using acid as a base, at this time, as for the reducing solution, hydracid is used, and next, the hollow building material is chemically tinned, by which the above problem is solved.例文帳に追加

この課題は、最初に中空建材の内部表面の鉛含有量を酸をベースとする還元水溶液で処理することによって減少させ、その際に還元溶液として水素酸を使用し、次いで中空建材を化学的に錫メッキすることによって解決される。 - 特許庁

The substituted conductive polyaniline copolymer is synthesized by adding aniline derivatives to which hydrogen and a hydrophobic substituent are each independently attached (with the proviso that the case in which each substituent is the hydrogen is excluded), and aniline to which no substituent is attached, in a prescribed molar ratio to a mixture of a hydracid and an organic solvent, and polymerizing them.例文帳に追加

水素酸と有機溶媒の混合物に、それぞれ独立して水素や疎水性の置換基が付着したアニリン誘導体（但し、いずれも水素の場合は除く)と置換基が付着していないアニリンとを所定のモル比で添加し重合させて置換された伝導性ポリアニリン共重合体を合成。 - 特許庁
