我厂量具产品,在正常情况下,能保证2～5年不锈。但装在木盒中的量具产品某些部位,不时出现锈蚀。例如经汽油清洗、涂BM—16防锈油、再包11~#气相防锈纸的块规,插入木盒隔板内的下半截部位;防锈方法与块规相同,但未包防锈纸的薄壳千分尺测杆外露部位;经汽油清洗,再装入聚乙烯塑料袋的V型架各个面等,其出现锈蚀的时间则不尽相同。从锈蚀部位和形貌看来,我们认为木盒内定有某种气相腐蚀因素存在。于是,我们对木盒材质和涂料进行分析和试验。
I plant measuring products, under normal circumstances, to ensure 2 to 5 years of stainless steel. However, some parts of the measuring tool installed in the wooden box, from time to time rust. For example, petrol cleaning, BM-16 anti-rust oil coating, and then pack 11 ~ # VCI paper block, insert the lower half of the partition within the wooden box; rust prevention methods and the same block, Paper shell micrometer rod exposed parts; the gasoline cleaning, and then into the polyethylene plastic bag V-shaped planes on all sides, etc., its rust time is not the same. From the rust site and topography, we think there is a wood-based gas corrosion factor exists. So, we analyze and test wood box materials and coatings.
