摘要： PURPOSE:To produce a molded product generating no thermal deterioration and excellent in strength and durability by a method wherein a specific high strength adding material is compounded with a cement base material containing an org. fiber reinforcing material and an extrusion aid and the resulting compd. is subjected to extrusion molding and the molded compd. is treated only with steam ageing until predetermined strength is obtained. CONSTITUTION:An org. fiber such as a pulp fiber is compounded with a cement base material constituted of cement and fine aggregate as a reinforcing material and, further, a high strength adding material composed of anhydrous gypsum and calcined alum is compounded with cement in an amt. of 5-30% by wt. of cement. The obtained compound is mixed by a mixer and kneaded along with water. This kneaded matter is subjected to extrusion molding by a screw extruder and the molded one is allowed to stand in a wet state for several hr and subsequently subjected to steam ageing at 60-80 deg.C for several hr. By this method, an extrusion molded product having high bending strength and durability can be obtained only by steam ageing.

摘要： When finely divided SHIRASU (pumice ejected from volcanoes and the secondary deposit of such pumice) is roasted at a temperature in the range of from about 800* to about 1200*C, the vitreous particles contained in said SHIRASU foam and consequently produce light-weight hollow glass microspheres. The hollow glass microspheres so produced are superior to conventional glass microspheres especially in their resistance to heat and can therefore be combined with metal, carbon, as well as with cement and other materials to produce novel lightweight composites.
摘要翻译：当分散的SHIRASU（从火山喷出的浮石和这种浮石的二次沉积物）在约800℃至约1200℃的温度范围内焙烧时，所述SHIRASU泡沫中包含的玻璃质颗粒因此产生轻质中空玻璃微球。如此制造的中空玻璃微球优于传统的玻璃微球，特别是在耐热性方面，因此可以与金属，碳，以及与水泥和其他材料结合，以生产新颖的轻质复合材料。

摘要： Disclosed is a method for the preparation of fine hollow glass spheres coated with titanium dioxide from particles of a volcanic vitreous deposit sand occurring in nature. The method comprises the steps of: (a) dispersing the starting particles in an aqueous medium containing hydrogen chloride (or sulfuric acid) and titanium chloride (or titanium sulfate); (b) admixing the aqueous dispersion of the particles with an aqueous alkaline solution such as a solution of ammonium hydrogencarbonate to effect hydrolysis of the titanium chloride (or sulfate) into hydrous titanium oxide forming a coating layer on the particles; and (c) subjecting the particles coated with hydrous titanium oxide to a heat treatment for expansion of the vitreous particles into hollow glass spheres with simultaneous conversion of the hydrous titanium oxide into titanium dioxide forming a coating layer on the hollow glass spheres.

摘要： PURPOSE:To reduce density by heating a pulverized and/or classified volcanic vitreous deposit in hydrochloric acid or sulfuric acid to make the compsn. of the surfaces layers of the grains different from that of the interiors, heat-treating the deposit under specified conditions and carrying out separation or classification. CONSTITUTION:A volcanic vitreous deposit is pulverized and classified into powder of about 5-10mum grain size and powder of about 10-20mum grain size. These powders and an about 2% hydrochloric acid soln. are sealed in a pressure vessel in 1:about 10 ratio, held at about 200 deg.C for about 120hr, cooled, filtered, washed and dried to form surface-treated powder. This powder is heat-treated by heating from room temp. to 900-1,100 deg.C within 1min and holding at 900-1,100 deg.C for several sec and the heat-treated powder is subjected to sink and float separation in water. Floating hyperfine hollow glass spheres of about 5-15mum grain size are obtd. from the powder of about 5-10mum grain size and those of about 10-30mum grain size from the powder of about 10-20mum grain size.
