概述
PA塑料(尼龙,聚酰胺),英文名称:Polyamide
PA的品种繁多,有PA6、PA66、PAll、PAl2、PA46、PA610、PA612、PAl010等,以及近几年开发的半芳香族尼龙PA6T和特种尼龙等很多新品种。
物理性能
比重:PA6 1.14克/立方厘米,PA66 1.15克/立方厘米,PA1010 1.05克/立方厘米
成型收缩率:PA6 0.8-2.5% ,PA66 1.5-2.2%
成型温度:220-300℃
干燥条件:100-110℃/12小时
坚韧、耐磨、耐油、,耐水、抗酶菌、但吸水大
燃烧鉴别方法:火焰上端黄色,下端蓝色,燃烧后塑料熔滴落,起泡,离火后特殊的羊毛,指甲烧焦味和带芹菜味
尼龙6: |
弹性好,冲击强度,吸水较大 |
尼龙66: |
性能优于尼龙6,强度高,耐磨性好 |
尼龙610: |
与尼龙66相似,但吸水小,刚度低 |
尼龙1010: |
半透明,吸水小。耐寒性较好。适于制作一般机械零件、减磨耐磨零件、传动零件以及化工、电器、仪表等零件 |
成型性能
1、结晶料,熔点较高,熔融温度范围窄,热稳定性差,料温超过300度、滞留时间超过30分钟即分解。较易吸湿,需干燥,含水量不得超过0.3%。
2、流动性好,易溢料。宜用自锁时喷嘴,并应加热。
3、成型收缩范围及收缩率大,方向性明显,易发生缩孔、变形等。
4、模温按塑件壁厚在20~90度范围内选取,注射压力按注射机类型、料温、塑件形状尺寸、模具浇注系统选定,成型周期按塑件壁厚选定。树脂粘度小时,注射、冷却时间应取长,并用白油作脱模剂。
5、模具浇注系统的形式和尺寸,增大流道和浇口尺寸可减少缩水。
聚酰胺的不足之处在于:由于热膨胀和吸水性所至的尺寸精度不够,耐酸性差,硬度和弹性模量不够。经改良以后,也是比较优秀的工程塑料之一。
