金属的防锈及产品的涂装,直接关系到机械产品的使用寿命和外观质量。但由于多方面的原因,较长时期以来不为人们所重视。为适应大型成套设备和日益增长的合作生产产品质量的要求,加强行业防锈涂装专业队伍的建设,西安重型机械研究所受机械部重型矿山工业局的委托, Metal rust prevention and product coating are directly related to the service life and appearance quality of mechanical products. However, for many reasons, it has not been valued by people for a long time. In order to meet the requirements of large-scale complete sets of equipment and the ever-increasing production quality of cooperative products, the construction of a professional anti-rust coating professional team was strengthened. The Xi’an Heavy Machinery Research Institute was commissioned by the Heavy Mining Industry Bureau of the Ministry of Machinery.
