涂层粉末第11部分:斜面流动测试

[中文适用范围]： 该文件规定了一种用于确定熔融热固性涂料粉末沿着与水平面成设定角度倾斜的平面的流动特性的比较方法。 本文件中描述的测试方法的目的是指示涂料粉末固化过程中可能发生的熔体流动程度。 该特性有助于改善表面外观以及锋利边缘的覆盖程度。 该测试是一种比较方法，用于检查给定涂料粉末的行为的批次间差异。 不同成分的涂料粉末的结果之间的相关性是不可预期的。 该方法不适用于根据 ISO 8130-6 表征时在测试温度下凝胶时间小于 1 分钟的涂料粉末。 此方法也不适用于有质感的粉末。 [外文原描述]： This document specifies a comparative method for determining the flow characteristic of a fused thermosetting coating powder down a plane inclined at a set angle to the horizontal. The aim of the test method described in this document gives an indication of the degree of melt flow that can occur during the curing of the coating powder. This characteristic contributes to the surface appearance and to the degree of coverage over sharp edges. The test is a comparative method for checking for batch to batch variation in the behaviour of a given coating powder. Correlation between the results from coating powders of differing composition is not to be expected. This method is not suitable for coating powders which have gel times of less than 1 min at the test temperature when characterised according to ISO 8130‑6. This method is also not suitable for textured powders.
