拆开报废钢丝绳,你会发现钢丝磨损非常严重,经常给钢丝绳涂油,就能延长钢丝绳使用寿命,就是因为天天给钢丝绳涂油,可以防止磨损与锈蚀。锰系磷化膜是一种耐磨保护涂层,可以大幅度提高钢丝的耐磨损与抗腐蚀能力,锰系磷化膜膜重15-30克/平米,它的耐磨损能力超过任何种类的润滑脂与润滑油,可以更好地防止磨损与锈蚀,锰系磷化耐磨涂层钢丝绳疲劳寿命是光面钢丝绳的三至五倍,锰系磷化膜膜重越大则使用寿命越长,但锰系磷化膜膜重不可以无限提高,锰系磷化膜膜重很难超过50克/平米,国内获得专利授权许可的企业生产锰系磷化耐磨涂层钢丝绳,锰系磷化膜膜重一般是在15-30克/平米之间,锰系磷化耐磨涂层钢丝绳是当今世界钢丝绳制造行业目前最先进技术,是各类光面钢丝绳的升级换代产品,使用寿命更长,单位使用成本更低,购买时注意磷化膜膜重范围。

煤矿机械配备的钢丝绳,使用环境比较恶劣,要求钢丝绳耐磨损能力越强越好。光面钢丝绳的钢丝是没有任何耐磨保护涂层的,容易磨损,磨损以后就会断丝,这是光面钢丝绳使用寿命比较短的原因。煤矿用锰系磷化耐磨涂层钢丝绳是近几年出现的新技术,钢丝表面有锰系磷化膜,锰系磷化膜是一种耐磨保护涂层,还有良好的防腐蚀能力,锰系磷化耐磨涂层电梯钢丝绳疲劳寿命是光面电梯钢丝绳疲劳寿命的三至四倍,目前,锰系磷化耐磨涂层矿用钢丝绳延长使用寿命的原理与锰系磷化耐磨涂层电梯钢丝绳是一样的,锰系磷化膜可以防止钢丝发生微动磨损与氧化锈蚀,这是使用寿命大幅度提高的原因。锰系磷化膜15克/平米是锰系磷化耐磨涂层矿用钢丝绳的基本技术指标,磷化膜膜重越大则耐磨损能力更高、使用寿命更长。锰系磷化耐磨涂层钢丝绳是光面钢丝绳的升级换代产品。

金属(主要指钢铁)经含有锌(Zn)、锰(Mn)、铬(Cr)、铁(Fe)等磷酸盐的溶液处理后,在基底金属表面形成一种不溶性磷酸盐膜,此种过程称为磷化。磷化使金属表面形成一层附着良好的保护膜,以磷酸锌为例,在氧化剂的存在下,所生成的磷化膜为Zn3(PO4)2·4H20和Zn2Fe(PO4)2·4H20的结晶体。该磷化膜闪烁有光、灰色多孔(空隙率为表面积的0.5%~1.5%膜厚通),常为0.1—50μm。
金属表面在除油、除锈后,为了防止重新生锈,通常要进行化学处理,使金属表面生成一层保护膜,该膜通常只有几微米,主要起增强涂层和底材附着力的作用,较厚的膜层还能增强防锈性能。
磷化的作用
磷酸盐转化膜应用于铁、铝、锌、镉及其合金上,既可当作最终精饰层,也可作为其他覆盖层的中间层,其作用主要有以下方面。
提高耐蚀性
磷化膜虽然薄,但由于它是一层非金属的不导电隔离层,能使金属工件表面的优良导体转变为不良导体,抑制金属工件表面微电池的形成,减少电化学反应,进而有效阻止涂膜的腐蚀。表1列出了磷化膜对金属耐蚀性能的影响。
提高基体与涂层间或其他有机精饰层间的附着力
磷化膜与金属工件是一个结合紧密的整体结构。其间没有明显界限。磷化膜具有的多孔性,使封闭剂、涂料等可以渗透到这些孔隙之中,与磷化膜紧密结合,从而使附着力提高。
提供清洁表面
磷化膜只有在无油污和无锈层的金属工件表面才能生长,因此,经过磷化处理的金属工件,可以提供清洁、均匀、无油脂和无锈蚀的表面。
改善材料的冷加工性能,如拉丝、拉管、挤压等。
改进表面摩擦性能,以促进其滑动。
