碳纤维表面化学镀镍工艺研究

介绍了聚丙烯腈基碳纤维表面化学镀镍的工艺流程,前处理包括去胶、除油、粗化、中和、敏化、活化和还原.探讨了碳纤维的去胶方法,优化了化学镀镍的配方.研究了主盐、还原剂、pH和施镀时间对碳纤维增重率的影响.结果表明,在400℃下灼烧30 min,可去胶完全.硫酸镍质量浓度为30 g/L、次磷酸钠质量浓度为35 g/L、pH为4.5左右及施镀时间为lh时,所得碳纤维的增重率最大.

Study of electroless nickel plating on surface of carbon fiber

The process flow of electroless nickel plating on the surface of polyacrylonitrile-based carbon fiber was introduced. The pretreatments include adhesive removal, degreasing, roughening, neutralizing, sensitizing, activating and reducing. The method of removing the adhesive on carbon fiber was studied, and the formulation for electroless nickel plating was optimized. The effects of principal salt, reducing agent, pH and plating time on weight gain rate of carbon fiber were discussed. The results showed that ...
