Description
結合水除去の温度かつ300〜1200℃の範囲の脱水物の安定化温度で、天然水和物、及び/又は合成した水和物、及び/又はそれらの混合物の脱水物から抽出された再生ナノ構造体は、安定した状態で、MgO、及び/又はSiO2、及び/又はAl2O3、及び/又はCaO、及び/又はFe2O3、及び/又はK2O、及び/又はNa2Oの中の酸化物を含み、かつ、接触するが混和しない多量の物質、すなわち、結合相とグレイン粒子(grain)とから構成される、集成体の2相のザクロ状の構造である。
再生ナノ構造体の実施例は、450℃の結合水除去温度で、かつ1100℃である脱水物の安定化温度で、天然の水和物の脱水物から得た再生ナノ構造体であり、そして、安定した状態で、金属酸化物MgO、SiO2、及びAl2O3を含有し、かつ、接触して混和しない多量の物質、すなわち、結合相及びグレイン粒子から構成される集成体のザクロ状の2相の構造である(図3)。
再生ナノ構造体は、SAE J300規格のSAE−10W−40粘度と、ACEA規格のACEA−A3性能特性とを有する潤滑油が利用される、85kWの能力を有するガソリンエンジンのトリートメント処理に利用される潤滑組成物に含まれる。
再生ナノ構造体の安定した構造を得る方法は、300〜900℃の範囲の結合水除去の温度での、天然の水和物、及び/又は合成された水和物、及び/又はそれらの混合物の脱水と、700〜1200℃の温度で、1〜3時間、脱水物の安定化と、MgO、及び/又はSiO2、及び/又はAl2O3、及び/又はCaO、及び/又はFe2O3、及び/又はK2O、及び/又はNa2Oの中の酸化物のグループを含有する潤滑媒体と生成物との混合と、摩擦面又は摩擦領域への混合物の導入とから構成される。100〜100,000nmの範囲の寸法の、再生ナノ構造体の提案した安定した構造は、摩擦面上での特定圧力と摩擦領域での温度とにより決定される回転体の安定した構造に変化するという事実に起因して固有のものである。
再生ナノ構造体の安定した構造を得る方法を実施する実施例は、接触するが混和しない多量の物質、すなわち、結合相とグレイン粒子とから構成される集成体の2相のザクロ状の構造体の形成からなる。この構造体は、構造体自身を、摩擦エリア又は摩擦ユニットに到達した後、「回転ナノベアリング」状に変質する。このような変質のプロセスは、潤滑間隔又は摩擦率により決定される。
