产品描述美华修复材料Mh1122

本品主要以疏水材料、超硬碳化硅及特性树脂为骨材的双组分复合材料，具有很好的疏水性、耐磨性能及粘接性能。

无挥发性有机溶剂，无闪点，施工方便、安全。使用温度范围在－5－100之间。

典型用途

主要用于电厂/水泥/化工/煤矿/冶金/钢铁各个车间的溜槽内壁。它具有较好的疏水性能，可以避免铁粉、灰尘等在内壁结垢，易清理。同时具有优异的粘接性能、操作工艺性好，满足大面积涂覆。

疏水性能测试：

水滴在表面不铺展，有自聚功能。

耐温性能：按照标准 GB7124 测试，碳钢片，表面喷砂处理， 70固化２４h 后冷至室温，于各个温度下进行测试。

 剪切强度与温度的关系图

从图中可以看出， 在 60以下的剪切强度〉10MPa，在 90也有 3MPa 的剪切强度。

常温固化不同时间的剪切强度对比：

按照标准 GB7124 测试，碳钢片，表面喷砂处理，恒温室 23±2条件下，固化不同时间的测试结果。
