山东玲珑轮胎股份有限公司开发出一种橡胶促进剂NS纯度检测新方法。称取促进剂NS样品,研磨至均匀的细粉末状;将细粉末状促进剂NS样品均匀铺平在坩埚底部,置入差示扫描量热仪炉体内进行测试;测试结束后,取出坩埚,进行纯度数据分析。该方法操作简单,不需要化学试剂溶解和作为流动相,节约了测试成本;需要测试时间约为20 min(液相色
Shandong Linglong Tire Co., Ltd. developed a new method for testing the NS purity of rubber accelerator. Weigh NS sample accelerator, grinding to a uniform fine powder; NS powder fine accelerator uniformly spread at the bottom of the crucible, placed in the differential scanning calorimeter furnace for testing; after the test, remove the crucible, Purity data analysis. The method is easy to operate, does not require chemical reagents to dissolve and as a mobile phase, saving test costs; requires a test time of about 20 min (liquid color
