被防鏽物的表面預處理方法: 1)表面清洁:清洗必须依被防锈物表面的性质和当时的条件,选定适当的方法。一般常用的有溶剂清洗法、化学处理清洁法和机械清洁法。 2)表面干燥清洗干净后可用过滤的干燥压缩空气吹干,或者用120~170℃的干燥器进行干燥,也可用干净纱布擦干。 涂敷防锈油的方法: 1)浸泡法:一些小型物品采用浸泡在防锈油脂中,让其表面粘附上一层防锈油脂的方法。油膜厚度可通过控制防锈油脂的温度或粘度来达到。 2)刷涂法用于不适用浸泡或喷涂的室外建筑设备或特殊形状的制品,刷涂时既要注意不产生堆积,也要注意防止漏涂。 3)喷雾法一些大型防锈物不能采用浸泡法涂油,一般用大约0.7Mpa压力的过滤压缩空气在空气清洁地方进行喷涂。喷雾法适用溶剂稀释型防锈油或薄层防锈油,但必须采用完善的防火和劳动保护措施。 Surface pretreatment methods of antirust: 1) surface cleaning: cleaning must be selected according to the properties of the surface of the antirust and the conditions at that time. Commonly used are solvent cleaning, chemical treatment cleaning and mechanical cleaning. 2) after drying and cleaning, it can be dried by filtered dry compressed air or dried at 120~170 C dryer or dry gauze. The method of coating antirust oil: 1) soaking method: some small items are soaked in antirust grease to make the surface adhere to a layer of antirust grease. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the antirust grease. 2) brushing is not suitable for outdoor building equipment or special shape products that are not suitable for immersion or spraying. When we brush, we should pay attention not to accumulate, but also to prevent leakage. 3) some large antirust objects in the spray method can not be soaked with soaking method. Generally, the compressed air of about 0.7Mpa pressure is used to spray the air in the air cleaning place. The spray method is suitable for the solvent diluted antirust oil or thin layer antirust oil, but the perfect fire protection and labor protection measures must be adopted
