涤纶织物化学镀Ni-P合金工艺

The process of Ni-P alloy chemical plating on polyester fabric

为了改善涤纶织物化学镀N i-P合金工艺存在的镀速慢、镀层质量差等问题,研究了镀液组分、pH值、超声波、稳定剂、络合剂、表面活性剂对涤纶织物化学镀N i-P合金镀层沉积速度、耐蚀性、导电性、拉伸强度和结合力的影响,得出了最佳镀液配方和工艺:N iSO420 g/L,NaH2PO215 g/L,NH4C l 30 g/L,温度50℃,施镀时间60 m in,pH 9,超声波功率72 W,稳定剂K IO38 mg/L,表面活性剂十二烷基苯磺酸钠50 mg/L,络合剂乳酸20 g/L。

To improve the deposition rate and quality of Ni - P chemical plating on polyester fabric, the influences of plating bath composition, pH value, ultrasonic wave, stabilizers and surface active agents and complex lactic acid on the deposition rate, corrosion resistance, conduction and tension strength of Ni - P chemical plated polyester fabric are investigated. The gained optimum formula and process are as follows： NiSO4（20g/L）, NaH2PO2 （15g/L）, NH4Cl （30g/L）, 50℃, 60min, pH 9, ultrasonic power 72W, stabilizer KIO3 （8mg/L）, surface active agent SBDS （50mg/L） and complex lactic acid（20g/L）.
