Description

一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺
技术领域
本发明涉及一种机械部件的处理工艺，具体涉及一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺。
背景技术
玉米制粉机是将玉米磨成粉状的器械，便于玉米的深加工。以前将玉米进行磨粉是通过石磨等器具进行人力操作，随着社会的发展，现几乎全都由机械设备代替。现有的玉米制粉机设备主要依靠磨辊对玉米进行粉碎研磨，最终制成粉状颗粒，磨辊通过磨辊轴承安放在机架上，因为玉米制粉机是食品器械，传统的防锈液涂抹在磨辊轴承上会存在污染产品的安全隐患，但磨辊轴承又会产生锈蚀现象，影响机械的寿命。现有的工业用黄油的性能与品质不能满足安全产品的加工要求。
发明内容
本发明旨在提供一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺。
本发明通过以下技术方案来实现：
一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺，包括如下步骤：
（1）除油：将磨辊轴承放到电解槽内脱脂，除油温度110~115℃，时间为15~18min；
（2）去杂：将磨辊轴承先放在质量分数为1.5%的小苏打水溶液中浸泡处理6min，然后取出用清水冲洗后再放入质量分数为2%的酒石酸水溶液中处理6min，取出用清水冲洗干净备用；
（3）发蓝：将去杂后的磨辊轴承放入发蓝液中浸泡处理8min，期间在发蓝液中通入电流大小为8~10A的交流电辅助发蓝处理，结束后取出用清水冲洗干净备用，所述的每升发蓝液溶液中含有下列重量的各原料：850g氢氧化钠、280g亚硝酸钠、60g磷酸三钠、2.5g氧化铁；
（4）冲洗：将发蓝后的磨辊轴承取出后放入流动的温水中冲洗40s，温水的温度控制为60~65℃；
（5）烘干：将冲洗后的磨辊轴承放入干燥箱中，控制烘干温度为75~80℃，25min后取出备用；采用75~80℃的温度烘干有利于保护蓝化后轴承表面膜的稳定性；
（6）防锈处理：将烘干后的磨辊轴承放入防锈油中浸泡30s，期间加热保持防锈油的温度为65~70℃，所述防锈油由如下重量份的物质制成：130份植物油、1份叔丁基对苯二酚、1份聚氧乙烯山梨糖醇酐单油酸酯、0.8份十二烷基醇聚氧乙烯醚硫酸钠、1.5份硬脂酸钠、2份丁基羟基茴香醚、1份高碳脂肪醇聚氧乙烯醚、1.5份二乙醇胺、0.5份魔芋胶、4份烯基丁二酸酯、0.5份二丁基羟基甲苯、2.2份纳米改性碳粉；
（6）保温处理：用吸油纸将磨辊轴承上多余防锈油吸去后，再将其放入恒温室内，保持温度为53~57℃，保温处理10min后即可。保温处理提高了轴承表面防锈油膜的均匀性和稳定性，并去除了过量的防锈油，进一步保证了产品的安全性。
进一步的，步骤（6）所述防锈油的制备方法为：将植物油加热至105~108℃，再将魔芋胶加入并不断搅拌均匀，然后将温度降至82~84℃，同时将叔丁基对苯二酚、聚氧乙烯山梨糖醇酐单油酸酯、十二烷基醇聚氧乙烯醚硫酸钠、硬脂酸钠、丁基羟基茴香醚、高碳脂肪醇聚氧乙烯醚、二乙醇胺、烯基丁二酸酯、二丁基羟基甲苯混入，用750~850rpm的转速搅拌5min后，最后将纳米改性碳粉加入，提高转速至1100~1200rpm，搅拌10min后即得防锈油。
进一步的，所述纳米改性碳粉的制备方法包括如下步骤：
（1）将石墨放入质量分数为2%的胡萝卜酸溶液中，浸渍15min后取出，然后放入质量分数为2%的小苏打溶液中，浸渍15min后取出，最后用清水冲洗后干燥备用；
（2）将干燥后的石墨放入质量分数为12%的氯化钾溶液中，保持溶液温度为30~35℃，同时施加频率为30KHz的超声波，15~18h后取出干燥得氯化改性石墨备用；
（3）将氯化改性石墨放入球磨机中，控制温度为-30~-25℃，不断研磨至粒径为30~35nm，得纳米石墨备用；
（4）将纳米石墨放入其质量3倍的植物油中，加热保持植物油温度为100~105℃，不断搅拌，30~35min后滤出干燥即得纳米改性石墨。改性后的纳米石墨吸附性能大大提升，其微粒结构呈片层状，有较好的润滑性，不仅能降低轴承摩擦时的磨损，又可吸附大量的防锈成分覆于轴承表面，防止其锈蚀，增强其防锈性能。
进一步的，所述植物油为亚麻籽油、橄榄油、大豆油中的任意一种。
本发明具有如下有益效果：本发明先对玉米制粉机磨辊轴承进行了蓝化处理，再将其放入特制的防锈油中进行防锈覆膜处理，其表面结构得到较好的改善，与传统磨辊轴承处理工艺相比，其抗氧防锈性能提升了28%以上，且轴承的耐磨性与寿命都得到提升。此外，本防锈油中有害成分较少，大大降低了安全隐患，又弥补了黄油的性能弊端，有很好的实用价值。

2.根据权利要求1所述的一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺，其特征在于，步骤（6）所述防锈油的制备方法为：将植物油加热至105~108℃，再将魔芋胶加入并不断搅拌均匀，然后将温度降至82~84℃，同时将叔丁基对苯二酚、聚氧乙烯山梨糖醇酐单油酸酯、十二烷基醇聚氧乙烯醚硫酸钠、硬脂酸钠、丁基羟基茴香醚、高碳脂肪醇聚氧乙烯醚、二乙醇胺、烯基丁二酸酯、二丁基羟基甲苯混入，用750~850rpm的转速搅拌5min后，最后将纳米改性碳粉加入，提高转速至1100~1200rpm，搅拌10min后即得防锈油。
3.根据权利要求1或2所述的一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺，其特征在于，所述纳米改性碳粉的制备方法包括如下步骤：
（1）将石墨放入质量分数为2%的胡萝卜酸溶液中，浸渍15min后取出，然后放入质量分数为2%的小苏打溶液中，浸渍15min后取出，最后用清水冲洗后干燥备用；
（2）将干燥后的石墨放入质量分数为12%的氯化钾溶液中，保持溶液温度为30~35℃，同时施加频率为30KHz的超声波，15~18h后取出干燥得氯化改性石墨备用；
（3）将氯化改性石墨放入球磨机中，控制温度为-30~-25℃，不断研磨至粒径为30~35nm，得纳米石墨备用；
（4）将纳米石墨放入其质量3倍的植物油中，加热保持植物油温度为100~105℃，不断搅拌，30~35min后滤出干燥即得纳米改性石墨。
4.根据权利要求1~3所述的一种玉米制粉机磨辊轴承表面发蓝防锈处理工艺，其特征在于，所述植物油为亚麻籽油、橄榄油、大豆油中的任意一种。
