蠡县液压泵全新A10VO28DFR1/31R-不同抗渗等级砼涂刷水泥基渗透结晶型防水涂料的抗渗性能试验对于未涂刷水泥基渗透结晶型防水涂料的空白试件，养护28d后进行抗渗试验直至渗水，测定其抗渗压力；另一组则在标准试件龄期为1d时，在试件迎水面涂刷水泥基渗透结晶型防水涂料3遍，养护28d后进行抗渗试验，测定其抗渗压力。测试结果及抗渗压力的对比百分率见表2。表2不同抗渗等级的混凝土涂刷水泥基渗透结晶型防水涂料的抗渗性能试验实验组别基准试件抗渗等级（设计值）涂刷时砼龄期基准试件涂刷试件抗渗压力增幅（%）抗渗压力（Mp养护龄期抗渗压力（Mp养护龄期1S4S6S8S91.9281.428565S1111.1281.828646S1211.2281.62833由表2试验结果可以看出，涂刷水泥基渗透结晶型防水涂料后，各试件的抗渗能力提高幅度与原空白试件抗渗等级有关，见下图一。

与电缆防火、钢结构防火涂料不同，饰面型防火涂料中的透明防火涂料的应用远远不够，即便是在国外也很少有完全成熟的产品，涂料体系的稳定性较差。目前在市场上还没有使用寿命过3年的产品。火涂料质量参差不齐，无法保证防火效果。饰面型防火涂料由于其生产工艺简单，设备要求低，而且有成熟的配方，门槛低、生产厂家比较多。由于企业的规模小，档次低，真正的质量管理体系大多没有建立。许多企业缺乏必要的原材料和成品检验手段，缺少经过专门培训的*检验人员，因此防火涂料的质量很不稳定。
