最近,日本一家金属用涂料剥离剂制造公司研究成功用化学方法即能简单分解、去除产生于钢铁表面“黑锈”的新型剥离剂,并且已付诸于实用化。 与以前占主要地位的物理方法相比,采用新型剥离剂除成本约降低一半外,还有如下优点:①完全没有噪音、粉尘等公害;②操作简单;③因为是膏状,即使对复杂形状的工件也能处理等。这对于建筑、造船、桥梁等必需对钢铁原材料进行加工的行业来 Recently, a Japanese manufacturer of coating strippers for metal used in chemical research successfully to the simple decomposition, removal of “black rust” from the steel surface of the new release agent, and has been put into practical use. Compared with the formerly dominant physical method, the new type of release agent has the following advantages except that the cost is reduced by about half: ① no noise, dust and other pollution; ② simple operation; ③ because it is a paste, even for complex shapes The workpiece can also be processed. This is for the construction, shipbuilding, bridges and other raw materials must be processed in the steel industry to
