摘要
采用全因子试验设计系统研究双螺杆转速、加工温度及喂料频率等关键工艺参数对断路器外壳材料阻燃尼龙耐黄变性能的影响。通过数据分析与验证,确定最佳的耐黄变性能工艺参数组合为:双螺杆转速300 r/min、加工温度250℃、喂料频率50 Hz,可以使得黄变值(Δb)稳定在0.06左右。研究成果深化了对阻燃尼龙材料耐黄变性能影响因素的理解,为实际生产中优化工艺参数、提升产品质量提供了科学依据和实用参考。
A systematic study was conducted using a full factor design of experiments to investigate the effects of key process parameters such as twin-screw speed,processing temperature,and feeding frequency on the yellowing resistance of flame-retardant nylon materials for circuit breaker casings.Through data analysis and verification,the optimal combination of process parameters for yellowing resistance was determined as follows:twin-screw speed of 300 r/min,processing temperature of 250 ℃,and feeding frequency of 50 Hz,which can stabilize the yellowing value(Δb) at around 0.06.This study not only deepens the understanding of the factors affecting the yellowing resistance of flame-retardant nylon materials,but also provides scientific basis and practical guidance for optimizing process parameters and improving product quality in actual production.
