不含有磨擦剂和任何石油化学溶剂,与真皮接触也不会脱色或腐蚀。
结果表明:涂层的冲蚀磨损受到攻角、冲速、磨料量等多种因素的影响。
磨料部分通过原子发射光谱和x射线衍射法进行金属元素及形态分析。
1·Silica gel column chromatography and solvent extraction were used to separate grease and abradant in a kind of excellent polishing paste for plastics, respectively.
分别采用硅胶柱色谱法和溶剂抽提,分离优质塑料抛光膏中的油脂和磨料部分。
2·The effects of water pressure, off distance, transverse speed, abrasive flow rate, abrasive grade and the kind of abradant to the effectiveness of rust -removing are analyzed.
并分析了压力、靶距、横移速度、磨料供给量、水流量、磨料粒度和磨料种类对除锈效率的影响,为磨料浆液除锈各参数的选择提供了参考。
