氨基磺酸镍添加剂镀层出现毛刺现象的原因是什么
来源:http://www.jnjrh.com 日期:2019-10-07 发布人:admin
  氨基磺酸镍添加剂的应用过程中,镀层有粗糙、毛刺5个原因,阿里调布添加剂在应用过程中,镀镍层应力低、极限强度高、沉积速度快、孔隙率低,再加上添加剂的使用,可以得到较好的外观。有时涂料出现毛刺、毛刺现象,影响涂料的质量,这是什么原因呢?
  In the application process of nickel sulfamate additive, there are five reasons for coating roughness and burr. In the application process of Ali distribution additive, nickel coating has low stress, high ultimate strength, fast deposition speed and low porosity. Additionally, the use of additive can obtain a better appearance. Sometimes, the burrs and burrs of paints affect the quality of paints. What are the reasons?
  根据现场经验和产品特点进行分析,主要包括以下五点:
  According to the field experience and product characteristics, the analysis mainly includes the following five points:
  1. 生产过程中,若槽内有固体悬浮物,应检查过滤泵是否正常工作,并保持过滤泵循环,对槽内进行过滤。
  1. In the production process, if there is solid suspended matter in the tank, the filter pump should be checked whether it works properly, and the filter pump circulation should be maintained to filter the tank.

  2. 镀液的pH值过高。高的电镀液pH值有良好的覆盖能力和阴极电流密度高,但高pH值会产生碱性镍盐沉淀在阴极附近,和涂层可能含有碱性镍盐,导致涂层的粗糙的结晶,影响涂层的机械性能。
  2. The pH value of the plating solution is too high. High pH value of electroplating bath has good coverage ability and high cathode current density, but high pH value will produce alkaline nickel salt precipitation near the cathode, and the coating may contain alkaline nickel salt, resulting in rough crystallization of the coating, affecting the mechanical properties of the coating.
  3、阳极泥或阳极袋在镀液中损坏,这些泥会导致镀层粗糙或毛刺现象。生产过程中应及时检查或更换阳极袋。
  3. Anode slime or bag is damaged in plating bath. These slimes can lead to rough or burr coating. The anode bag should be inspected or replaced in time during the production process.
  4、阴极电流密度过高,镀层高的区域亮度会降低,镀层比较粗糙。电流密度应控制在工艺范围内。
  4. If the cathode current density is too high, the brightness of the area with high coating will decrease and the coating will be rough. The current density should be controlled within the process range.
  5. 钙离子被加入水中。钙离子不会在阴极上还原为金属钙离子,在镀液中,钙离子会在沉积污染镀层后达到平衡,导致镀镍层出现细小颗粒,从而影响镀层的质量。在生产过程中,对于不含钙离子的纯水,应加装罐,以减少钙杂质的影响。
  5. Calcium ions are added to water. Calcium ions will not be reduced to metal calcium ions on the cathode. In the plating bath, calcium ions will balance after depositing the contaminated coating, resulting in the appearance of fine particles in the nickel plating layer, thus affecting the quality of the coating. In the process of production, pure water without calcium ions should be canned to reduce the influence of calcium impurities.
  氨基磺酸镍是一种较为昂贵的镀镍工艺,在生产过程中更要注意以上几点,避免镀层粗糙、毛刺现象,减少故障,节约成本,还可以更好地使用镍磺酸盐添加剂。如果您对氨基磺酸镍添加剂感兴趣,请联系氨基磺酸厂家客服索取免费样品和详细的技术信息!本文来源:http://www.jnjrh.comNickel sulfamate is a relatively expensive nickel plating process. In the production process, more attention should be paid to the above points to avoid coating rough, burr phenomenon, reduce faults, save costs, and better use of nickel sulfonate additives. If you are interested in nickel sulfamate additives, please contact the customer service of the sulfamate manufacturer for free samples and detailed technical information.
