PA66基本物:PA66至今仍是重要的品种。PA66的熔点、抗张强度、抗弯强度以及硬度都是尼龙家族中的,所以被广泛用于各个领域,随着聚合物-无机纳米复合材料研究的深入。在较高温度也能保持较强的强度和刚度。PA66的熔点:260℃ ;它是一种半晶体-晶体材料。PA66对许多溶剂具有抗溶,但对酸和其它一些氯化剂的抵抗力较弱。 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%。PA66的粘较低,因此流动很好。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。在成型后仍然具有吸湿,其程度主要取决于材料的组成、壁厚以及环境条件。在产品设计时,一定要考虑吸湿对几何稳定的影响。
PA66加工的流道和浇口:由于 PA66 的凝固时间很短,因此浇口的位置非常重要。浇口孔径不要小于 0.5*t(这里 t 为塑件厚度)。如果使用热流道,浇口尺寸应比使用常规流道小一些, 因为热流道能够帮助阻止材料过早凝固。如果用潜入式浇口,浇口的小直径应当是0.75。
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.
Introduction to PA66: nylon (nylon), Chinese ne polyide, English ne polyide (PA), is the general ne of thermopstic resin containing repeating ide group - [nhco] - on the main chain. Its ne is determined by the specific number of carbon atoms in the synthetic monomer. It was invented by the fous chemist Carlos of DuPont company, the rgest chemical industry company in the United States, and his research te. Nylon PA66; polyhexanediine; polyide 66, abbreviated as nylon 66. CAS No.: 32131-17-2 nylon PA66 has the highest mechanical strength and the most widely used variety in PA series. Because of its high crystallinity, it has high rigidity and heat resistance
