涂料粉末第12部分:相容性的测定

[中文适用范围]： 本文件规定了一种目视方法，用于确定混合两种不同涂料粉末时最终涂层表面质量的恶化程度。 表面质量取决于涂料粉末的以下特性： a) 化学反应性； b) 化学成分； c) 熔体性能。 外观上的不相容性、其性质和程度将在很大程度上取决于粉末的混合比例。 表面外观不相容性的本质可以通过多种方式表现出来，如第 8 条所述。 该测试可用于预测在制造过程和涂料粉末应用过程中混合不同粉末而产生不相容性的可能性。 本文件仅涉及涂层视觉方面的变化。 该混合物系列还可用于测试机械性能、化学性能、腐蚀性能和抗紫外线辐射性能等性能。 更多属性可以由感兴趣的各方商定。 [外文原描述]： This document specifies a visual method to determine the deterioration of surface quality of the final coating when mixing two different coating powders. The surface quality will depend on the following characteristics of the coating powders: a) the chemical reactivity; b) the chemical composition; c) the melt properties. The onset of the incompatibility in appearance, its nature and its extent will depend greatly on the ratio in which the powders are mixed. The nature of the incompatibility in surface appearance can manifest itself in various ways, described in Clause 8. This test is useful in predicting the possibility of incompatibility arising from mixing different powders both during the manufacturing process and during the application of the coating powder. This document concerns only changes in visual aspects of the coating. The mixture series can also be used for testing properties such as mechanical properties, chemical properties, corrosive properties and resistance against UV radiation. Further properties can be agreed between interested parties.
