PA66工艺:干燥处理:如果加工前材料是密封的,那么就没有必要干燥。然而,如果储存容器被打开,那么建议在 85℃ 的 热空气中干燥处理。如果湿度大于 0.2%,还需要进行105℃,12 小时的真空干燥。 熔化温度:260~290℃。对玻璃添加剂的产品为275~280℃。熔化温度应避免高于 300℃。
Zytel PA66 / 6 uses pstics for sporting goods:
Helmet manucturer DXL protion chooses DuPont ™ Zytel Nylon resin is due to its high resistance, rigidity and toughness. This super tough nylon is reinforced with 33% gss fiber. The four helmet parts made with Zytel are the , the C-shaped "buckle" around the head and two side s. The patented four part design makes the helmet more suitable for the head than the traditional one part helmet.
Runner and gate of PA66 processing: because the solidification time of PA66 is very short, the location of gate is very important. The gate dieter should not be less than 0.5 * t (where t is the thickness of the pstic part). If a hot runner is used, the gate size should be smaller than that of a conventional runner, as the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum dieter of the gate should be 0.75.
PA66 的粘较低,因此流动很好(但不如 PA6)。这个质可以用来加工很薄的元件。 它的粘度对温度变化很敏感。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 has low viscosity, so it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is in the range of 1% ~ 2%, and it can be reduced to 0.2% ~ 1% by adding gss fiber additive. The difference of shrinkage rate in the process dirion and in the dirion perpendicur to the process dirion is rger.
