等离子表面处理技术在塑料行业的应用

QQ图片20200218153727.png

      由于大多数塑料材料的表面张力很低,因此过去的很多设计往往是迁就材料,只要在经过一定的等离子表面处理后表面能达到了喷涂或粘接等工艺的要求,就优先考虑使用这种材料。


      近年来,成本和材料的使用特性等则日益成为产品设计的主导因素,从而使汽车制造商们开始将眼光投向了更多的塑料品种。目前,PP、PC、ABS、SMC、各种弹性体以及各种复合材料等已在汽车制造中得到了广泛应用。在这种情况下,不仅要处理好同一材料部件之间的相互粘接问题,还要解决好不同材料部件之间的相互粘接问题,而以往的等离子表面处理方法显然难以满足这一加工制程的要求。


      就等离子表面处理效果而言,目前所有的表面处理方法中,氟化处理的效果是最好的,它能使材料获得永久粘接力。但是,这种方法会产生大量的有害气体,对废气的处理成本令大多数汽车厂商难以接受。


      但是令人欣慰的是,等离子表面处理技术的出现为塑料行业带来了一场革新,等离子表面处理技术具有以下优势: 1. 环保技术:等离子表面处理作用过程是气固相干式反应,不消耗水资源、无须添加化学药剂 2. 效率高:整个工艺能在较短的时间内完成  3. 成本低:装置简单,容易操作维修,少量气体代替了昂贵的清洗液,同时也无处理废液成本  4. 处理更精细:能够深入微细孔眼和凹陷的内部并完成清洗任务  5. 适用性广:等离子表面处理技术能够实现对大多数固态物质的处理,因此应用的领域非常广泛 

                                                  Application of plasma surface treatment technology in plastics industry

    Because the surface tension of most plastic materials is very low, so many designs in the past tend to accommodate materials. As long as the surface can meet the requirements of spraying or bonding process after a certain plasma surface treatment, the use of this material is preferred.


    In recent years, the cost and the use characteristics of materials are increasingly becoming the leading factors in product design, which makes automobile manufacturers begin to focus on more plastic varieties. At present, PP, PC, ABS, SMC, various elastomers and various composite materials have been widely used in automobile manufacturing. In this case, we should not only deal with the problem of mutual bonding between the same material parts, but also solve the problem of mutual bonding between different material parts. However, the previous plasma surface treatment methods are obviously difficult to meet the requirements of this process.


   As far as the effect of plasma surface treatment is concerned, among all surface treatment methods at present, the effect of fluorination treatment is the best, which can make the material obtain permanent adhesion. However, this method will produce a lot of harmful gases, and the cost of waste gas treatment is unacceptable to most automobile manufacturers.


  However, it is gratifying that the emergence of plasma surface treatment technology has brought an innovation to the plastic industry. Plasma surface treatment technology has the following advantages: 1. Environmental protection technology: the plasma surface treatment process is gas-solid coherent reaction, does not consume water resources, and does not need to add chemicals 2. High efficiency: the whole process can be completed in a short time 3 Low cost: the device is simple, easy to operate and maintain, a small amount of gas replaces the expensive cleaning liquid, and there is no cost to treat the waste liquid at the same time. 4. More refined treatment: it can penetrate into the interior of the micro holes and depressions and complete the cleaning task. 5. Wide applicability: plasma surface treatment technology can achieve the treatment of most solid substances, so it is widely used in many fields。
