The Improvement of Durability and the Prevention of Adhesion of Waterlives for Concrete by Thermal Spraying Process

在本研究中，可以通过在混凝土表面涂上金属层或陶瓷层来完成如下所示的事情。1)提高耐久性2)防止水生物的粘附3)用作景观材料4)用作精炼中的电磁屏蔽材料根据上述各项对应的结果总结如下。进行了8年的实际环境（内陆地区屋顶、share飞溅区、粪便处理槽）暴露试验、2400小时的气象仪加速暴露试验和300次循环的冻融试验。根据这些结果，对这些喷涂涂层进行填充中空处理，可以明显提高涂层的耐久性。根据SAROMA湖10年（含盐量：3.1-3.3%）的观察结果，在防止水藻、贝类、海纲等水生生物的附着方面，铜涂层和锌基喷涂涂料代替有机锡基防污涂料具有广阔的应用前景。由于在该钢船的船体喷镀铜和镀镀13%铝锌的部位发现了附着的贝类，为解决这一问题，1995年6月开始了新的试验。在对30个地方的准确施工进行8年连续观察的基础上，肯定了喷涂涂料的实用价值。同时，根据6种彩色陶瓷喷涂涂层300次加速暴露试验结果，也证实了涂层的耐候性。在电磁屏蔽中的应用测试了铜涂层、锌涂层、碳钢涂层、felite涂层和金属箔的电磁屏蔽效果。结果表明，该方法可方便地为现有不同类型的建筑材料提供电磁屏蔽功能。少

In this research, the things shown below can be done by coating the surface of concrete with metallic layr or ceramic layr.1) To improve the durability2) To prevent from adhesion of aquatic organism3) To be applied as landscape material4) To be used as the material of electromagnetic shielding in refiningThe results corresponding to every heading shown above are summarized as follows.1.The improvement of the durabilityThe exposing test of 8-years in actural environment (the roof of inland areas, the splash zone of share, the tank of excrements disposal), the accelerated exposing test of 2400-hours with weather meter and the freeze & fusion test of 300 cycles were done. According to these results that the filling hollow treatment were done for these sprayd coatings, it has become clear that the durability can be remarkably improved.2.The prevention of adhesion of waterlivesIn the light of the observing result of 10-years in the SAROMA Lake (salt : 3.1-3.3%), it can be said that copper s … More prayd coating and zinc group sprayd coating have bright future in place of antifouling paint of organo tin group in aspect of preventing from adhesion of aquatic organism just as algae, shellfish and ascidium. Because the adherent shellfish was found in the parts of the body of the steel ship in which there were copper sprayd coating and 13% Al-Zn sprayd coating, to counter this, the new experiment has begun on June 1995.3.The application to landscape materialOn the basis of the result observed continuously for 8-years to the accural construction of 30 places, the utility value of the sprayd coating has been affirmed. At the same time, the weather resistance has been confirmed too in accordance with the result of the accelerated exposing test of 300 cycles for 6 kinds of color ceramic sprayd coating.4.The application to electromagnetic shieldingThe electromognetic shielding effectiveness of copper sprayd coating, zinc sprayd coating, carbon steel sprayd coating, felite sprayd coating and metallic foil were measured. According to these results, it has been evendiated that by this method, electromagnetic shielding function can be easily provided to the different kinds of the existing building materials. Less
