510-58 Special particle size distribution analyzer-air jet sieve for plastic materials N6-PA polyamide fiber (nylon)
Special particle size distribution analyzer-air jet sieve for plastic materials N6-PA polyamide fiber (nylon). Nylon 6 is polycaprolactam, and nylon 66 is 聚己二酸己二胺. Nylon 66 is 12% harder than nylon 6. In theory, the higher the hardness is, the more brittle the fiber is, and the easier it will break. But in carpet use this slight difference is indistinguishable. PA has a good comprehensive performance, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating, and low friction coefficient, has a certain flame retardant, easy to process, suitable for glass fiber and other fillers fill reinforce modification, improve the performance and expand the scope of application. There are many varieties of PA, including PA6, PA66, Pall, PA12, PAl010, etc., as well as many new varieties of semi-aromatic nylon PA6T and special nylon developed in recent years. Nylon-6 plastic products can adopt metal sodium, sodium hydroxide as main catalysts, acetyl caprolactam as the cocatalyst. δ-caprolactam is directly in the model through negative ion ring polymerization. We call it pouring nylon. This method facilitates the manufacture of large plastic parts. This property determines that only the air jet sieve can be used for accurate particle size analysis.
