Research on mariner growth prevention and anticorrosion tests of new type high toughness Resin/Steel/Copper alloy system

摘要

Multicomponent piping structure is common in ocean engineering material system. The new type of high toughness resin, marine steel and copper alloy as the main materials of the system is selected. The materials tests have been carried on in aging resistance, adhesion, water absorption, alternating temperature, salt spray resistance, weathering, electrochemical, antifouling and mariner growth prevention. The performances of the materials are analyzed by the quantitative results. The analysis shows that the high toughness resin coated on copper alloy materials and hull steel materials has good adhesion, water absorption, seawater resistance, alternating temperature resistance and salt spray resistance performances. Weathering performance meets the usage requirements of marine engineering. The electrochemical performance of the hull steel, copper alloy and high toughness resin materials is stable in seawater. High toughness resin/steel/copper alloy system has good anticorrosion, antifouling performance. The multicomponent piping system can satisfy the application in marine shipping requirements.
