摘要:
An adhesive material for aging prevention which can eliminate problems of conventional compositions for aging prevention and can prevent a crosslinked rubber from aging; and a method of preventing a crosslinked rubber from aging. The adhesive material for aging prevention comprises 100 parts by mass of at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and 5-50 parts by mass of an antidegradant. The method of preventing crosslinked-rubber aging comprises applying an adhesive material for aging prevention comprising at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and an antidegradant to a crosslinked rubber to allow the antidegradant to migrate to the crosslinked rubber and thereby prevent the crosslinked rubber from aging.
摘要:
A method and a system for assisting steering and mooring alongside of vessels that enables operators to easily obtain physical relationship between two vessels and the states of mooring lines and fenders when the operators lay the two vessels aboard and moors them alongside for loading cargoes are provided. Physical relationship between a hull of the first vessel (1) and a hull of the second vessel (2) is calculated in the form of numerical data based on information on a reference position of a first vessel (1) that is detected by a first GPS receiver, information on a reference position of a second vessel (2) that is detected by a second GPS receiver, oscillation information on the first vessel, oscillation information on the second vessel, information on a distance between the two vessels that is measured by distance measuring device, coordinate data including hull outer shape and the like against the reference position for each vessel, and air pressure data for each fender. Information on the physical relationship between the hull of said first vessel (1) and the hull of said second vessel (2) based on the numerical data and the state of each fender are displayed on a first display device provided for a steering room of the first vessel and a second display device provided for a steering room of the second vessel by means of animation.
摘要:
An adhesive sheet material for aging prevention which can eliminate problems of conventional compositions for aging prevention and can prevent a crosslinked rubber from aging; and a method of preventing a crosslinked rubber from aging. The adhesive sheet material for aging prevention comprises 100 parts by mass of at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and 5-50 parts by mass of an antioxidant. The method of preventing crosslinked-rubber aging comprises applying an adhesive sheet material for aging prevention comprising at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and an antioxidant to a crosslinked rubber to allow the antioxidant to migrate to the crosslinked rubber and thereby prevent the crosslinked rubber from aging.
