    摘要: This invention is based on the discovery by the inventors that, if a preliminary hydration hardening process and a full-scale hydration hardening process are provided after the molding process, and a process for burning a hardened body of cement at a high temperature is provided between the preliminary and full-scale hardening processes, it is possible to obtain a molded product of cement having a higher mechanical strength than any such product according to any known method including no such burning process.According to this invention, there is provided a method of manufacturing a product of cement having high mechanical strength, which method comprises the steps in sequence of adding water, and if required, glass fibers or other reinforcing material, into a mixture of cement and an aggregate, and kneading the whole completely; molding the kneaded mixture into a desired shape; hardening the molded body preliminarily by hydration; burning the preliminarily hardened body at a high temperature; and hardening the burned body on a full scale by hydration.

    摘要: A novel method for producing a high-strength inorganic cement article is provided. The method comprises kneading under high shearing force a cement mixture containing as essential components hydraulic cement, a hydrophilic organic binder and water, molding the kneaded mixture into an article having a water-to-solid weight ratio of not more than about 0.2, preliminarily hydrating the molded article, firing the preliminarily hydrated article at about 300.degree. to about 1000.degree. C., and then rehydrating the fired article. The resulting cement article has bending strength of not lower than about 200 kgf/sq.cm without fibrous reinforcing materials and has that of not lower than about 350 kgf/sq.cm when reinforced with heat-resistant fiber materials. The cement article can be advantageously glazed in the above mentioned method by applying a glazing agent to a desired surface of the preliminarily hydrated article and then firing the article.

    摘要: The process of the present invention uses an aminoaldehyde polycondensate as capsule-wall and a hydrophobic core material dispersed in an aqueous acidic solution containing an anionic water-soluble colloidal substance, wherein it is characterized in that the anionic water-soluble colloidal substance comprises a mixture of an anionic water-soluble substance having a high viscosity and that having a low viscosity.The process of the present invention provides a slight viscosity rise in the encapsulation, a capsule slurry with a high concentration, low viscosity, and a slight smudging in the application as a pressure-sensitive recording sheet and the like, compared with the conventional processes.

    摘要: The present invention relates to a color-former having microcapsules which comprise an electron-donating colorless dye dispersed in a hydrophobic liquid. The present invention provides a color-former using both an electron-donating colorless dye and a hydrophobic liquid which previously were unable to be used because of the lack of solubility. A uniform and stable dispersion of electron-donating colorless dye in a hydrophobic core liquid is prepared by using oil-soluble non-ionic surfactant.
