建筑外墙底漆抗泛碱性和基材加固性的实效测试方法

Test Methods of Alkali Resistance and Reinforcing Property for Architectural Exterior Wall Primer

在JG/T 210—2007《建筑内外墙用底漆》中"6.12附着力"和"6.14抗泛碱性"所描述试验方法的基础上加以改进,探究出了一种可同时快速有效地判断建筑外墙用底漆抗泛碱性的趋势和对基材加固性的试验方法:在穿孔纤维水泥板上批刮腻子,刷涂底漆、铁蓝溶液和弹性中涂漆,石蜡封边后进行检测,结果以铁蓝变色面积与弹性中涂漆剥离面积、难易程度来判定。试验方法更符合实际工程效果、简单、直观、结果准确且对比性强。

Based on the test methods in Article 6.12 Adhesion and Article 6.14 Alkali Resistance described in JG/T 210--2007 Architectural Interior and Exterior Wall Primer, fast and new test methods for alkali resistance and reinforcing property are invented： firstly perforated fiber-cement sheet is coated with putty; primer, secondly iron blue solution and elastic surfacer are coated; finally, paraffin wax is applied. Test results are evaluated by the color change area of iron blue, pick-off area of surfacer and pick-off difficulty of surface. The test methods are efficient, simple, direct, and exact with good comparison.
