    摘要： A cementitious composition may include polyvinyl alcohol, high alumina cement, water, a metallic coagent, a peroxide crosslinking initiator, and an organic acid retardant. A molded article may be manufactured from the cementitious composition by preparing a hydrogel pre-polymer blend of saponified polyvinyl alcohol acetate (PVAA) with greater than or equal to approximately 85% saponified PVAA, and water, mixing the hydrogel pre-polymer blend with high alumina cement (HAC) using a high shear mixing process, mixing in a metallic coagent and a peroxide crosslinking initiator, mixing in an organic acid retardant, and hot press molding the mixture.

    摘要： The following describes a novel and alternative mechanism in regards to releasing reactive chemicals. Namely, utilizing shells containing multiple emulsions that can be blended with the base fluids, and then react with said base fluid upon exposure to a trigger e.g. high shear and/or elongation flow, therefore plugging even large fractures. Such gelling lost circulation material allows to obtain a reliable carrier and fast reaction when triggered.

    摘要： A chromium-free treating liquid and treatment methods which are for imparting to a zinc or zinc alloy deposit a coating film which is highly corrosion-resistant, has a uniform appearance free from sag stains/puddle stains, has no failure concerning thickness unevenness, and has satisfactory adhesion. The surface-treating aqueous solution, which is for forming a corrosion-resistant coating film over a zinc or zinc alloy deposit, is characterized by comprising (a) an alkali metal silicate (M2O.nSiO2 (wherein M represents an alkali metal and n indicates SiO2/M2O molar ratio)), (b) a water-soluble or water-dispersible silane coupling agent, and (c) a water-soluble or water-dispersible glycidyl ether compound. One of the surface treatment methods for forming a highly corrosion-resistant coating film over a zinc or zinc alloy deposit includes bringing the surface of the zinc or zinc alloy deposit into contact with the surface-treating aqueous solution. The surface-treating aqueous solution is applicable also to the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit and free from hexavalent chromium or from chromium in any form. Namely, another surface treatment method for forming a highly corrosion-resistant coating film over a zinc or zinc alloy deposit comprises bringing the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit into contact with the surface-treating aqueous solution. Furthermore provided is a highly corrosion-resistant coating film formed by bringing the solution into contact with the surface of a zinc or zinc alloy deposit or with the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit.
