解决方案 | 三孚新科汽车零部件板块环保镀锌技术
Date: 2023-06-09 Click: 4115



在汽车行业中,镀锌是极具性价比的“关键部件”表面处理方式,比如在汽车制动卡钳、制动管以及动力转向系统部件、紧固件等均有应用。同时,镀锌工艺也广泛应用于重型电气传动部件和坦克、装甲运兵车等军工领域。

 

此前,我们已介绍过三孚新科通用镀锌及钝化产品。而在汽车、军工等领域,对零部件表面性能有更高要求。此次,我们将以汽车制动卡钳为例,重点介绍三孚新科镀锌工艺在该板块的应用。


 

汽车制动卡钳


作为汽车制动系统中的关键零部件,汽车制动卡钳在使用过程中由于工作环境非常恶劣,刹车高温、沙石撞击等都对其表面处理工艺提出了很高要求。目前,市场上主流的卡钳材质是耐磨高强度的碳素钢。这种钢的硬度能够使它长时间的用作刹车卡钳,而不会被磨坏。但其表面粗糙,存在大量的砂眼和气孔等铸造过程缺陷,在表面防腐处理上难度较大。

 

当前主流的卡钳镀锌方案有电镀酸锌+碱锌+三价铬钝化以及电镀酸锌+三价铬钝化两种工艺,对产品的寿命、品质等需求已经基本满足。但传统酸锌添加剂属于油性配方,废水排放COD较高,环保性能欠缺。


 

三孚新科汽车零部件板块环保镀锌技术

 

针对以上问题,三孚新科推出水性酸锌添加剂,配合高效无氰碱锌及三价铬钝化工艺,产品整体性能优于传统镀锌工艺,特别在安全性及环保性上优势明显。目前已经在国内某知名品牌汽车卡钳电镀产线上规模应用。


 

三孚新科环保镀锌技术特点

 

01 / 水性酸锌特性

 


  • 水基配方。消耗量低,达到常规油性添加剂水平;
  • COD数值只有常规油性添加剂的约1/6~1/5;
  • 应用广泛,适应以下基材电镀:可锻铁、铸件、热处理钢及碳氮化钢。适用于滚、挂镀工艺;
  • 可在宽量程电流密度中操作,挂镀、滚镀的高、低电流密度区均能镀出各种形状复杂的镀件;
  • 在标准件上,镀出工件较传统光亮剂更均匀、钝化色差小、饱满度高、特别是淬火工件效果极佳;
  • 不需使用甲醇配制,废水处理成本更低,使用更加环保。


 


02 / 碱性镀锌特点

 


  • 延展性优越,即使镀厚镀层也无剥落、起泡现象;适用于挂、滚镀;
  • 无氰配方,可直接转换使用传统氰化镀锌相同的电镀设备,无额外设备支出;
  • 分布均匀且覆盖均匀;
  • 电镀电流密度范围广,高、低电流密度均可镀出形状复杂的镀件;
  • 可获得不同颜色的耐蚀性镀层,性能超过汽车制造商标准;
  • 耐高温性能极佳,即便达到45 ℃仍能保持光亮度。


 


03 / 三价铬钝化特点

 


  • 适用于各类镀锌;可对应挂镀、滚镀。耐蚀性能优越,可产生光亮的保护镀层;
  • 耐热性能优越;
  • 5% 白锈抗盐雾测试时间可达96小时以上。不腐蚀锌层,使用寿命长;
  • 不含六价铬,减少废水处理成本。


 


Plus技术 无硼化酸锌工艺

 

为了更好的应对国家对表面处理行业的环保管控要求,三孚新科已成功开发无硼化酸锌工艺,该技术可完美覆盖水性酸锌及油性酸锌,同时具有以下特点:

 


  • 无硼配方,更加环保。杂质少,有效减少过氧化氢用量;
  • 代硼组分含活性成分,比传统工艺产生更光亮镀层;同时可显著提高镀锌层分散能力;
  • 钝化膜结合力好,抗腐蚀能力强。
