      不锈钢屏风在清除表面油污的技术上有很多种,有好也有坏,这都是根据屏风的材质而定的。哪一种材质的屏风就选择哪一种除油方式。下面我们就说说阴极与阳极的除油性能:

      Stainless steel screen in the removal of surface oil technology has many kinds, good or bad, which are based on the material and the screen. What kind of material on the screen to choose what kind of way of removing oil. Here we talk about the oil removal performance of cathode and anode:

      阴极除油的优点是:析出氢气泡多且小,乳化作用强,故除油速度快;阴极附近溶液pH值升高对除油有利;能除去氧化物,使钝化的不锈钢装饰屏风表面活化;不腐蚀不锈钢装饰屏风基体。缺点是:容易造成不锈钢装饰屏风渗氢,导致鼓泡和氢脆,对于高强度钢和合金钢不适用;溶液中的杂质可能在不锈钢装饰屏风表面析出(挂灰);油污和其他污染物有可能重新沉积到不锈钢装饰屏风上,就需要保持除油液相对的干净,污染要少。

      Cathode in addition to the advantages of oil are: precipitation hydrogen bubble and small, strong emulsification, so in addition to the high speed of oil; near the cathode solution pH value increased favorable for oil removal, to remove the oxide, the passivation of stainless steel decorative screen surface activation; no corrosion of stainless steel decorative screen matrix. Disadvantages: easy to cause the stainless steel decorative screen hydrogen permeation, leading to hydrogen embrittlement and bubbling, for high strength steel and alloy steel is not applicable; impurities in the solution may in stainless steel decorative screen surface precipitation (hanging ash), oil and other pollutants may re deposited onto stainless steel decorative screen, you need to keep in addition to oil relatively clean, make less pollution.

      阳极除油的优点是:没有清脆和挂灰问题。缺点是:除油速度较慢,这是因为在相同电流密度下析氧量只有析氢量的一半;阳极附近溶液pH值下降对除油不利;析出氧可使某些金属氧化,甚至油膜氧化而难以除去。有些金属会发生腐蚀。

     The advantages of anode oil removal: there is no clear and hanging ash. Disadvantages are: in addition to the oil slowly. This is because half of the oxygen evolution only hydrogen amount in the same current density; near the anode solution pH value decreased except for adverse oil; oxygen evolution can make some metal oxide, and even oil film oxidation and difficult to remove. Some metal corrosion.

     而阳极除油被经常用作标准的电解除油操作,因为阳极反应可以清除掉不锈钢装饰屏风上的颗粒状的污物。同时氧气产生于不锈钢装饰屏风,像高镍含量的合金,非常容易形成氧化物。在这些情况下,就必须非常小心地选择电解除油之后的酸活化工艺。使用周期变向电流,对许多基材都非常有用。使用阳极电流或周期变向电流,可以减少高应力合金的氢脆现象。在阴极和阳极循环之间的变换,对去除污渍和氧化物可以达到非常好的活化效果。在这种时候,不锈钢装饰屏风从电解除油槽出槽时,最好是在阳极阶段提出不锈钢装饰屏风。

      In addition to the anode electrolytic degreasing operation oil is often used as the standard, because the anodic reaction can remove the stainless steel decorative screen granular dirt. At the same time the oxygen produced in the stainless steel decorative screen, like alloy with high nickel content, very easy to form oxide. In these cases, you must be very careful in the choice of electrolytic degreasing after acid activation process. The use of change to the current cycle, on many substrates are very useful. The use of the anode current or change to the current cycle, can reduce the high hydrogen embrittlement force alloy. Between the cathode and the anode in the cycle of transformation, on the removal of dirt and oxide can achieve very good activation effect. At this time, stainless steel decorative screens from the electrolytic degreasing bath bath, preferably in the anode phase of stainless steel decorative screen.
