BONDING METHOD FOR SULFUR SOLIDIFIED MOLDED PRODUCT, MANUFACTURING METHOD FOR SULFUR SOLIDIFIED MOLDED PRODUCT, AND SULFUR SOLIDIFIED MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a structure comprising a sulfur solidified molded product having resistance against an environment having a temperature difference and corrosion properties.;SOLUTION: Panels 11 are bonded so that side surfaces 13 (end surfaces) to be bonded are abutted to each other and mutually opposed grooves 14 are provided to the side surfaces 13 in the up and down direction in the figure. A solid sulfur rod 17 (bonding material) comprising sulfur alone or a mixture mainly comprising sulfur is inserted in the bonding part 16 demarcated by both abutted grooves 14 and a floor surface 15 along with an energizing heater 18 (heat generating means) of which the leading end part generates heat by energization. A current is supplied to the leading end of the energizing heater 18 to melt the leading end part of the sulfur rod 17 adjacent to the leading end part (the bottom part in the figure) of the heater at 119-159°C to liquefy the same and the bottom part of the bonding part 16 is filled with liquid sulfur and this sulfur is subsequently cured at the normal temperature.;COPYRIGHT: (C)2004,JPO
