铸铜雕塑因常年在户外受自然力侵蚀，表面易出现漏孔，加上与游人零距离接触，触摸造成古铜效果脱落严重，既存在安全隐患又影响艺术表现效果，需要及时养护。 而以往，雕塑的古铜效果传统工艺一般采用热处理，使用液化气喷火枪使雕塑表面上升到特定温度，涂抹化学材料，经多次清洗加热达到最终效果，污染大、程序复杂。市环雕所专业技术人员积极探索维护新工艺和材料配方，改变传统模式进行古铜着色处理，新工艺选用新型药水，反复调整配比，冷处理使雕塑表面自然渐变，达到理想色度后用喷涂与推光方式进行仿古锈处理，最后喷涂水性环保保护膜。
The cast copper sculpture is eroded by natural force in the outdoors for years, and the surface is prone to leak, plus the contact with the visitors at zero distance. The touch causes the effect of the bronze to fall off seriously, not only the hidden danger but also the artistic expression effect, so it is necessary to maintain the effect in time. In the past, the traditional process of bronze sculpture was usually treated by heat treatment. The surface of the sculpture was raised to a specific temperature by using LPG spray gun, and the chemical material was applied to the final effect by cleaning and heating several times. The pollution was large and the program was complicated. The professional technicians of the city ring carvings actively explore and maintain the new technology and material formula, change the traditional model for the bronze coloring treatment, the new technology selects the new type of water, adjust the ratio repeatedly and the cold treatment to make the surface of the sculpture natural gradually change, after reaching the ideal color, the antique rust treatment is carried out by spraying and pushing light, and the water quality is finally sprayed.
