环氧富锌和无机福锌漆适合划格法试验吗？？

HJ120

如题所示，这两种漆适合做划格法试验吗？为什么？有标准依据吗？

个人体会，拿锤子砸，漆膜不掉，说明附着力没问题/:victory

没有说不可以吧

HJ120

总是感觉不好！

renliu521

也想了解

Epoxy

无机锌不适合用划格法，因为颜料太多

没说不可以，看你自己的产品了，其实连水性无机富锌底漆都可以做的(可以达到0级）。

为什么我做的醇溶性无机富锌底漆表面很粗糙呢 且附着力不好

杨红波

用的哪里的树脂？基础配方怎么样？

划格不可怕，可怕的是有个项目要水性富锌花圈法到1级，如果试板处理的不合适，很容易出现问题。但是各个厂家的不同，有的厂家是附着力好，但是柔韧性差，各有优势吧。

不适合！

1. 见ISO 2409-2007：
The method is not suitable for coatings of total thickness greater than 250 μm or for textured coatings.
NOTE 2 The method, when applied to coatings designed to give a rough patterned surface, will give results which will show too much variation (see also ISO 16276-2).
2. 见ISO 16276-2-2007
The cross-cut test is suitable for film thicknesses up to 250 μm. The X-cut test is not limited by thickness.
For hard coatings, it might not be possible to use the cross-cut test, in which case the X-cut test should be
used.
For coatings containing pigments that have a flake format, the assessment of either the cross-cut or the X-cutmight be misleading. The coating manufacturer should be consulted for recommendations.

最好都用拉拔法，TB/T 1527-2011、JT 722-2008对涂料附着力要求都是5MPa以上，普遍采用拉拔法检测。

铁路标准1527，水性无机富锌划格法2级。
不过最好还是拉开法。

我的环氧富锌，划圈一级，至于划格，不好操作啊，劲小了漆膜毫无损伤，主要感觉还是跟膜厚有关吧。

基本不推荐哦，道理我也不是太清楚哦

干的太快  干喷？

一般使用拉拔法测定附着力，水性富锌漆一般用画格法测定附着力。

不可以 。看10楼的详解

防腐配套产品通常都是用拉拔测试附着的
