【摘要】 通过实验研究,本文定义并探讨了吸附型固载二氧化氯产品的释放特性参数,并以临界释放速率Uc=0.005μg/h.cm³作为释放终点,将产品分为长效、快速和中速释放三种类型。长效型产品释放速率峰值U_max<20μg/h.cm³,峰值时间τ_max>360h,有效释放时间τ_cs>60d;快速释放型产品U_max>60μg/h.cm³,τ_max<12h,τ_cs<7d,中速释放型产品则处于两者之间。文章还讨论了固载二氧化氯产品释放特性的控制方法和不同类型产品的适用范围,质量控制原理与要求,为产品释放特性的定量研究和应用开发提供了依据。更多还原

【Abstract】 The performance parameter of the 21SJ series absorption type solid chlorine dioxide determined and defined for are going to explain release characteristic by experimental study.The absorption type solid chlorine dioxide is divided into three types of long-time,fast and moderate speed release in accordance with critical release rata Uc= 0.005μg/h.cm~3 for end release.The release rata peak value Umax<20μg/h.cm~3,The peak value timeτmax>360h,The effctive release timeτcs>60day for the long-time type;The release rata peak value Umax>60μg/h.cm~3,The peak value timeτmax<12h,The effctive release timeτcs<7day for the fast speed release type;It is mean value for the moderate speed release type.The control method of release characteristic and the scope of application of differential types products are discussed and The quality control principle and standards.They can provide basis for quantitative study and utilization.更多还原
