PURPOSE:To provide a cutting tool made of surface coated cBN base ceramics excellent in adhesion of hard coating layer to the surface of a base material. CONSTITUTION:The cutting tool made of surface coated cBN base ceramics is produced by forming a hard coating layer, consisting of a single layer of one kind among TiC, TiN, TiCN, TiCO, TiCNO, and Al2O3 or duplex layers of two or more kinds among them, by vapor deposition to 5-20mum average layer thickness on the surface of a base material which has a composition consisting of 20-50vol.% of ceramic binding phase and the balance cBN dispersed phase and where the above ceramic binding phase is removed by means of ion etching treatment over the depth of 0.5-5mum from the outermost surface and the surface is roughened by the remaining cBN dispersed phase. By this method, the cutting tool having excellent properties over a long period can be obtained. |

PURPOSE:To make it possible to remove efflorescence and remove its regeneration by forming a waterproof agent with specified cyanogen compound or their low condensates and coating the surface of an efflorescence generated material with the waterproof agent and impregnating and then pickling the surface of the material. CONSTITUTION:About 100w.t. of decyltrimethoxy silane is diluted in about 900w.t. isopropyr alcohol so as to produce a diluent. As an efflorescence elimination method, an efflorescence suspected material is coated with a waterproof diluent of about 100g/m<2>, impregnated and cured for about three days. Then, the material is pickled with an aqueous solution produced by 35% concentrated hydrochloric acid and washed with water, thereby eliminating the efflorescence. Furthermore, the surface of the material is coated with a diluent of a waterproof agent by about 200g/cm<2> and impregnated and cured, which prevents the penetration of acid water of the material and hence inhibits the generation of acid corrosion on the surface and prevents the regeneration of efflorescence. |

PROBLEM TO BE SOLVED: To provide a repairing method for a concrete water-passage wall by which a degraded part appearing on a wall surface of a concrete water-passage structure used for hydraulics-related facilities like an industrial water-passage or an agricultural water-passage is removed and fine cracks or the like formed in the surface after the construction can be restrained by improving the strength, as well as to provide the concrete water-passage wall structure.
SOLUTION: The repairing method for the concrete water-passage wall includes a foundation treatment process for removing the weakened part of the wall including an area of the surrounding normal wall part to expose a sound part inside the normal concrete, and a coating process for coating the sound part with a mortar base material including an organic fiber. The repairing method also includes a successive laying process in which an embedding material is embedded in the mortar base material of a successive joint part of a side face and a floor face of the water-passage wall. The concrete water-passage wall structure 10 has an alkali-resistant glass fiber sheet F and mortar base material layers 12, 13 including a chopped fiber which are formed on a structural cross section perpendicular to the direction of flow of the water passage W by means of the repairing method for the concrete water-passage wall.

PROBLEM TO BE SOLVED: To obtain a cleaning liquid with which white dew produced on the surface of a concrete product such as a cement brick can be rapidly, accurately and safely removed. SOLUTION: This cleaning liquid is an aq. soln. prepared by dissolving sulfamic acid, citric acid, silicon and ethylene diamine tetraacetic acid in water. Namely, sulfamic acid is a strong acid which dissolves a calcium compd. in concrete which is a strong alkali material by neutralization. Citric acid separates calcium in concrete by a chelating effect. Silicon covers bubbles (strong acid) of chlorine gas produced by the neutralization between sulfamic acid and concrete by immediately masking the bubbles produced. Ethylene diamine tetraacetic acid masks the electrolyte of white dew separated and prevents redeposition of the white dew. By allowing to proceed the chemical reaction above chemicals at one time, white dew on the concrete surface can be removed. Contaminants produced by cleaning are washed away with water. |

PURPOSE: To surely remove a matter stuck with cement by keeping an object soaked in a container filled with an acidic liquid to an extent that the object is slightly immersed, in a specified period of time, then extracting the acidic liquid from the container, and allowing a cleaning water to pass through the container.
CONSTITUTION: A container 7 is internally composed of a treatment chamber 3 and a dehydration passage 5, a feeder tubular path 2 connected to the top of the container 7 and a draining tubular path 6 connected to the bottom. If a filter 4 is clogged due to the attachment of a foreign matter W stuck with cement, dilute hydrochloric acid is introduced into the container 7 from the draining tubular path 6, so that the filter 4 is slightly immersed in the container 7. Further, the filter 4 is kept soaked for a specified period of time in such a state that the filter 4 is slightly soaked in the dilute hydrochloric acid. Next, the dilute hydrochloric acid filled in the container 7 is drained from the draining tubular path 6. After that, a cleaning water is introduced into the container 7 from the draining tubular path 6 and is allowed to flow out of the feeder tubular path 2. Thus it is possible to remove the matter stuck with cement easily from the filter 4.
