Copper doors require little maintenance, but derive from one of the main advantages of your installation through indoor doors, which require little maintenance. Of course, this material is sensitive to water, but it can be used as a simple preventive maintenance. You can only pay for it with copper doors, which increase the life expectancy of manifolds.

　　如果你可以使用的漆面，生活的改善令人难以置信。室内门通常是机会的划痕和凹陷可能会发生，因为他们少接触比无论是从自然，或外部攻击人类，适当的密封门，表面，所以你可以为他们的强度和耐久性的奇迹工作的青铜大门。

　　If you can use paint, the improvement of life is incredible. Indoor doors are often scratched and dented by chance, because they have less contact than bronze doors that attack humans from nature or outside, properly sealed doors, and surfaces, so you can work for the miracle of their strength and durability.

　　减少能源和公用事业的成本，与他们的生活，你可以大大降低您的能源及基础设施成本的室内门温暖的光辉。在你每月的账单会导致较低，尤其是在冬天。铜可以减少室内加热器和其他设备的要求，这必然意味着减少的电力消耗和较低的电费。这些门也是优良的绝缘体，当你觉得其中有些失去绝缘能力，在一定程度上，您可以随时添加铜门泡沫核心，这样可以防止热量损失影响。

　　By reducing the cost of energy and utilities, and their lives, you can greatly reduce the cost of your energy and infrastructure by the warm glow of indoor doors. Your monthly bills can lead to lower bills, especially in winter. Copper can reduce the requirements of indoor heaters and other equipment, which necessarily means less power consumption and lower electricity costs. These doors are also excellent insulators. When you feel that some of them are insulated, you can add copper foam core to a certain extent, so that the heat loss can be prevented.

　　铜雕塑保护维修方法

　　Protection and Maintenance of Copper Sculpture氧化接触氧化银及氧化亚铜，封闭外露的表面的氯化亚铜，达到控制的青铜器的腐蚀的目的。通过机械手段，排除粉状锈，揭露灰色白色蜡氯化亚铜。氧化银然后调成糊状酒精，应用于表面的氯化亚铜和放在潮湿的环境，使其充分的一部分形式氧化亚铜和氯化铜、 氯化亚铜的表面覆盖。既为盐，所以多个操作直到放置在高湿度环境中不是粉状的稳定性生锈腐蚀点为止。这种方法是适合的器皿和器具与金属镶嵌的斑点局部腐蚀。
                                  

　　The corrosion of bronzes can be controlled by oxidizing contact with silver oxide and cuprous oxide and sealing the exposed surface with cuprous chloride. By mechanical means, the powder rust was eliminated and the grey white wax cuprous chloride was exposed. Silver oxide is then blended into paste alcohol, which is applied to the surface of cuprous chloride and placed in a humid environment to cover the surface of cuprous oxide, cuprous chloride and cuprous chloride in a sufficient part. Since it is salt, multiple operations are carried out until a stable rust corrosion point is not powdered in a high humidity environment. This method is suitable for speckle localized corrosion of utensils and utensils inlaid with metal.

　　碱性浸泡法地方锈蚀青铜一半在碳酸钠溶液中浸泡，逐渐转换为稳定的碳酸铜，铜氯的氯化铜流离失所提取。提取的需要定时的更换，直到液体有无氯离子发生。然后反复洗涤用蒸馏水去除碱液，干保护。碱液提取氯化物，保留一层层五颜六色的孔雀石和其他腐蚀性、 不损害到原始的青铜色。这个缺点是更换时间;其他氯化物不只连接到不锈钢表面和腐蚀已侵入地壳深、 难以更换完成。

　　In alkaline immersion method, half of the locally corroded bronze was immersed in sodium carbonate solution and gradually converted to stable copper carbonate. Copper chloride of copper chloride was displaced and extracted. The extraction needs to be replaced regularly until chloride ions occur in the liquid. Then repeated washing with distilled water to remove lye, dry protection. Alkali extracts chloride, retaining layers of colorful malachite and other corrosive, without damaging the original bronze color. This disadvantage is replacement time; other chlorides are not only connected to the surface of stainless steel, and corrosion has penetrated deep into the crust and is difficult to replace.
