PA66德国巴斯夫 A3X2G5工艺：
PA66的收缩率在1%~2%之间，加入玻璃纤维添加剂可以将收缩率降低到0.2%~1%。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。PA66塑料热性质熔点即结晶熔解时的温度，对结晶性高分子PA66塑料，显示清晰的熔点，根据采用的测试方法，熔点在259~267℃的范围内波动。通常采用差热分析法测出的PA66塑料的熔点为264℃。如果将体积膨胀系数显示极大值的温度当作熔点，则尼龙-66的熔点温度范围为246~263℃。接近理论熔解温度259℃。PA66塑料的注塑特性干燥处理：如果加工前材料是密封的，那么就没有必要干燥。如果储存容器被打开，那么建议在85C的热空气中干燥处理。如果湿度大于0.2%，还需要进行105C，12小时的真空干燥。
PA66 BASF A3X2G5Process:
The shrinkage rate of PA66ranges from 1% to 2%, and adding glass fiber additives can reducethe shrinkage rate to 0.2% to 1%. The difference in shrinkage ratebetween the process direction and the direction perpendicular tothe process direction is significant. The thermal melting point ofPA66 plastic refers to the temperature at which crystallizationmelts. For crystalline polymer PA66 plastic, the melting point isclearly displayed, and according to the testing method used, themelting point fluctuates between 259 and 267 ℃. The melting pointof PA66 plastic, usually measured by differential thermal analysis,is 264 ℃. If the temperature at which the maximum volume expansioncoefficient is displayed is taken as the melting point, the meltingpoint temperature range of nylon 66 is 246~263 ℃. Approaching thetheoretical melting temperature of 259 ℃. Drying treatment forinjection molding characteristics of PA66 plastic: If the materialis sealed before processing, there is no need to dry it. However,if the storage container is opened, it is recommended to dry it inhot air at 85C. If the humidity is greater than 0.2%, a vacuumdrying at 105C for 12 hours is required.
