螺钉、螺帽、圆柱销、挡圈和垫圈等标准紧固件是机电产品中常用的零件。据统计上海地区22个标准件生产厂,全年用钢量达10万余吨。但由于长期来在标准件生产过程中防锈技术落后,造成钢材和能源的浪费。例如:由于原材料生产厂对出厂的原材料没有采取有效的防锈措施,遇到多雨季节,一般不到24小时,原材料表面就会出现锈蚀:一般性气候,48小时后也会出现锈蚀。用这种有锈蚀的材料加工成的产品也必然带有锈蚀,据了解标准件发黑处理产品出厂不满三个月就出现锈蚀,严重影响产品质量。针对上海地区湿度高,温差大;标准件产品成筐清洗、成批涂油、成堆包装和油膜极易碰破等特点,我们制订了一套防锈方法,经试用,效果较好:原材料的防锈期由1～2天提高到20天以上;产品的防锈期由6个月提高到一年以上,现将其方法简介如下: Standard fasteners such as screws, nuts, pins, retaining rings and washers are commonly used parts in electromechanical products. According to the statistics of 22 standard parts production plants in Shanghai, the annual amount of steel amounted to more than 100,000 tons. However, due to the lack of anti-rust technology in the standard parts production process for a long time, resulting in the waste of steel and energy. For example, since raw material factories do not take effective anti-rust measures to the factory raw materials, rainy seasons usually occur in less than 24 hours, and rusting occurs on the surface of the raw materials: the general climate will also appear rusting after 48 hours. It is also inevitable that the products processed with such corroded materials will be rusty. It is understood that the corrosion of standard black parts is less than three months before delivery, which seriously affects the quality of products. For the high humidity in Shanghai, the temperature difference is large; standard parts into a basket cleaning, batching oil, piles of packaging and easy to touch the oil film and other characteristics, we developed a set of rust-proof method, the trial, the better: raw materials Anti-rust period from 1 to 2 days to 20 days or more; anti-rust product from 6 months to more than one year, now the method is as follows:
