涂料和清漆.利用质量均衡估算法计算防污漆中杀生物剂释放率的建模

[中文适用范围]： 本国际标准规定了一种使用质量平衡计算来估计防污涂料在其整个使用寿命（使用期间）内杀菌剂平均释放率的方法。 如果需要，还可以计算指定油漆寿命的前 14 天内杀菌剂的累积总释放量。 本国际标准适用于任何释放杀菌剂的防污涂料。 当防污涂料释放或假定释放多于一种杀生物剂时，可以重复计算以获得每种杀生物剂的释放速率的估计值。 计算得出的涂层在其使用寿命期间释放的杀菌剂总量的估计值可以被视为释放到环境中的最大量的最坏情况，因此计算出的平均释放率值也应被视为最大可能的平均释放量涂料使用寿命内的速率。 计算出的估计值适用于一般环境风险评估，应用适当的修正因子将可以在相关场景和风险评估案例中做出最准确和最具代表性的环境风险评估[4]。 没有限制该方法使用的释放速率的最小或最大限值。 该国际标准主要针对应用于船舶和船体的防污涂料中生物杀灭剂的释放。 然而，它也可以用于估计应用于其他物体的防污涂料中的杀菌剂释放量。 [外文原描述]： ISO 10890:2010 specifies a method for estimating the mean release rate of biocide from an antifouling paint over its entire lifetime (in-service period) using a mass-balance calculation. If required, the cumulative total release of biocide over the first 14 days of the specified paint lifetime can also be calculated. The standard is applicable to any antifouling paint that releases a biocide. Where an antifouling paint releases, or is assumed to release, more than one biocide, the calculation can be repeated to allow estimates of the release rate of each biocide to be obtained. The calculated estimate of the total amount of biocide released by the coating over its lifetime can be considered as a worst case for the maximum amount released to the environment, and so the calculated mean release rate value should also be considered as the maximum possible mean release rate over the lifetime of the paint. The calculated estimates are suitable for use in general environmental risk assessments, and the application of appropriate correction factors will allow the most accurate and representative environmental risk assessment to be made in the relevant scenario and risk assessment case. There are no minimum or maximum limiting values of release rate which restrict the use of the method. The standard is primarily directed towards the release of biocide from antifouling paints that have been applied to ship and boat hulls. It can, however, also be used for estimating biocide release from antifouling paints that have been applied to other objects.
