在本研究中，根据ISO 6529、ASTM F739和EN 374-3标准试验方法，使用两个渗透室研究了丁腈和氯丁橡胶手套对苯和1，2-二氯乙烷的渗透性。渗透系数随收集介质流速的增加而显著增加。对于ISO 6529和ASTM F739细胞，合适的氮气收集流速应分别高于75和150毫升/分钟。对于开环系统，ISO 6529电池的渗透系数明显大于ASTM F739电池，两者之间的差异具有统计学意义。另一方面，无论是ISO 6529细胞还是ASTM F739细胞，在不同的氮气收集流量下，穿透时间都在20-30分钟左右。菲克扩散系数和树脂在聚合物手套中的溶解度可以指定为标准方法的替代测试结果。(C)2007爱思唯尔有限公司。保留所有权利。
In this study, the permeation resistance of nitrile and neoprene gloves to benzene and 1,2-dichloroethane was investigated using two permeation cells according to the ISO 6529, ASTM F739, and EN 374-3 standard test methods. The permeability coefficients were found to significantly increase with the flow rate of the collection medium. The appropriate flow rate of nitrogen collection should be higher than 75 and 150mL/min for the ISO 6529 and ASTM F739 cells, respectively. For an open-loop system, the permeability coefficient of the ISO 6529 cell was obviously greater than that of the ASTM F739 cell, and the difference between these two cells was statistically significant. On the other hand, the breakthrough time was about 20-30 min for either the ISO 6529 or ASTM F739 cell at different flow rates of nitrogen collection. Fick's diffusion coefficient and solubility of permeant in the polymer glove can be specified as alternative test results for standard methods. (c) 2007 Elsevier Ltd. All rights reserved.
