标准范围

本文件规定了一种目测方法，用于在混合两种不同的涂层粉末时确定最终涂层表面质量的劣化。表面质量取决于涂层粉末的以下特性:a） 化学反应性；b） 化学成分；c） 熔体性质。外观不相容性的开始、性质和程度将在很大程度上取决于粉末的混合比例。如第8条所述，表面外观不相容的性质可以以各种方式表现出来。该试验有助于预测在制造过程中和涂覆粉末过程中混合不同粉末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。其他财产可由相关方商定。

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.
