把由粘性油和石蜡充分混合的混合物涂到钢铁或有色金属表面作为润滑剂或保护涂层。可用刷涂或喷涂法涂抹。石蜡最好是碳原子数约为20的纯石蜡,在室温下为固体。不希望含有羰基,也可以使用非石油石蜡如蜂蜡。与只用油相比,润滑剂或涂层的消散变慢。因 Apply a mixture of viscous oil and paraffin to a steel or non-ferrous surface as a lubricant or protective coating. Can be painted or spray coating method. The paraffin wax is preferably a pure paraffin having about 20 carbon atoms and is solid at room temperature. It is not desirable to have a carbonyl group, and non-petroleum waxes such as beeswax may also be used. The lubricant or coating dissipates more slowly than oil alone. because
