国产与进口促进剂NS性能对比

通过对国产与进口促进剂ＮＳ理化性能、胶料物理性能和硫化特性的测试表明：国产促进剂ＮＳ理化性能和实际使用性能均接近国外样品的水平，可以替代进口产品。指出国产促进剂ＮＳ需要作以下改进：进一步降低灰分含量，提高纯度；发展造粒产品；降低生产成本，确保产品质量稳定。

Comparison between Properties of Accelerator NS Made in China and Imported One

A comparative test was made on the chemicophysical nature of accelerator NS made in China and imported one, and their in rubber physical properties and curing charateristics The results showed that the chemicophysical nature and the properies in service of accelerator NS made in China were similar to those of imported one and it was suitable to replace the latter It was pointed that the accelerator NS made in China needed to be improved by the following measures: to lower the ash content and to increase the purity; to develop the granular product; and to decrease the cost and to increase the stability of product quality
