コンクリート防護粒子コロイドは、主にケイ酸ナトリウム、ケイ酸カリウムとから構成される。 その特徴は、ケイ酸ナトリウムとケイ酸カリウムは直径:1〜100nmの超微細固体粒子であり、ケイ酸ナトリウムと、ケイ酸カリウムの比率は、3.2〜4.2:1。 コロイド中の超微細固体粒子の総量と水の総量の重量比は、26〜30%:74〜70%。
本発明の利点は、超微細固体粒子が高度分散されるコロイドは、コンクリート毛細孔中で水和化物と化学反応する主体であるイオンを超微細固体粒子に変えた。
コンクリート構造体に対して全体隔離層と局部隔離層の二重隔離保護層を作り出す。 それを基礎とし、粒子コロイドの特性とゲルの特性を有機的に結合させ、全体に働きかけ、腐食媒質の侵入と侵食を抑止することにより、コンクリート構造物への長期かつ安定的に有効な保護を実現する。 さらに、コンクリート構造の耐久性を向上させ、実際使用寿命を延ばし、メンテナンスコストを軽減する。

291 Method for treating concrete by making use of electrochemical treatment JP22369394 1994-09-19 JPH0891958A 1996-04-09 SAKAI HIROTOMO; ASHIDA KIMINOBU
PURPOSE: To prevent the deterioration of concrete surface by electric current injection to suppress the fall in the pH value of the electrolyte solution on the surface. CONSTITUTION: An electric current is applied to a concrete, through the electrolyte solution held on the surface of the concrete, by injecting the current between external electrodes set up on the surface and/or between the external electrode(s) and the reinforcing steel bars inside the concrete serving as internal electrodes, to control the pH level of the electrolyte solution to 7 or higher.
292 Method and system for protecting oxidizable material against oxidation JP29606493 1993-11-01 JPH07313866A 1995-12-05 ROORENSU PIKETEIIREIDEIE; JIYANNMARUKU DORUBOO; JIERAARU RUSOO
PURPOSE: To protect a material from being oxidized by oxidizing gaseous flow by injecting an inert oxigen-free protective gas at a higher speed than that of the oxidizing gaseous flow through the inner surface of the material. CONSTITUTION: The material 1 has an outer surface 2 coming into contact with the oxidizing gaseous flow 4 and an inner surface 6 opposite to the outer surface 2. An oxygen-free protective gas 8 such as nitrogen is injected through the inner surface 6 of the material 1 at a higher speed than that of the oxidizing gaseous flow. At this time, a gas-tight wall 10 is provided behind the surface 6 to form an injection chamber 12 by partitioning the wall 10 and the surface 6 so that the protecting gas does not diffuse into the whole of the inside of the material 1. Thereby, the rate of entering oxygen into the inside of the pores of the material 1 is restricted, and the oxygen content of the gas layer contacting with the outer surface 2 of the material 1 is suppressed, and further, active parts of the material 1 are blocked.

297 Anisotropic etching of niobium pentaoxide JP9137593 1993-04-19 JPH06122980A 1994-05-06 MONTE EI DAGURASU; HAWAADO AARU BERATAN; SUKOTSUTO AARU SAMAAFUERUTO
PURPOSE: To provide a method for anisotropic etching of niobium pentaoxide. CONSTITUTION: A niobium pentaoxide substrate 34 is immersed into a liquid ambient (e.g., 10% hydrofluoric acid 30) and is illuminated by the electromagnetic radiation (e.g., collimated visible/ultraviolet radiation 24) produced by a radiation source (e.g., a 200 Watt mercury xenon arc lamp 20). A window 26 which is substantially transparent to the collimated electromagnetic radiation 24 allows the radiated energy to reach the Nb 2O 5 substrate 34. An etch mask (e.g., org. photoresist 32) may be positioned between the radiation source 20 and the substrate 34. The Nb 2O 5 substrate 34 and the liquid ambient 30 are maintained at a nominal temp. (e.g., 25°C). Without illumination, the Nb 2O 5 is not appreciably etched by the liquid ambient. Upon illumination, the etch rate is substantial ly increased. COPYRIGHT: (C)1994,JPO
