摘　　要：化学镀镀前的活化工艺至关重要,它对化学镀镀层的性能影响很大.对杨木单板化学镀镀前的活化液种类、活化时间及活化温度对镀后杨木单板电磁屏蔽效果影响的研究结果表明,活化杨木单板比较理想的活化液为活化液NO.3,适宜的活化时间为6min,活化温度为室温(24℃).最佳工艺条件下,镀后杨木单板的电磁屏蔽效果达到50～60 dB.Activation process of electroless plating is very important and has more effects on properties of nikle - plate. In this paper, effects of activation solution, activation time and activation temperature on electromagnetic shielding properties of nikle - plate were studied. The results showed that the suitable activation solution is No.2, and optimum activation time is 6 min and activation temperature is room teperature. The electromagnetic shielding properties is up to 50 - 60 dB under the optimum process.
