【摘要】 研究了溶剂法在尼龙1212粉末生产中应用的可行性,并讨论了溶剂配比、恒温湿度、恒温时间等因素对尼龙1212粉末粒度的影响。试验结果表明,采用溶剂法可有效地生产尼龙1212粉末,生产的最佳工艺条件为:尼龙树脂:溶剂=1:20,恒温温度为180℃,恒温时间为8h。在此工艺条件下生产的尼龙1212粉末的72μm筛通过率可达85％以上。更多还原

【Abstract】 The application of solvent method in the preparation of nylon 1212 powder was investigated, including the influence of various technological conditions, such as the dosage of the solvent, processing temperature and the constant temperature time. The experimental data show that using solvent method can effectively produce nylon 1212 powder, and the optimal technological conditions are: nylon resin/solvent = 1/20, processing temperature being about 180°C , constant temperature time being about 8 hours. With proper technological conditions, the passage of nylon powder through 75 μm screen can reach 85%.更多还原
