水泥制品的外观缺陷,根据国家标准规定,有的可以采取适当的修补措施加以解决。以往,我们曾用水泥砂浆和环氧树脂一乙二胺等材料修补,但前者易脱落,不牢固,后者因乙二胺有毒,工人不愿使用。后来,我们通过开展QC小组活动,应用HS—812环氧树脂水乳胶泥修补,取得了良好的效果,并制订了相应的操作规程。一、修补材料及配制方法 HS—812环氧树脂水乳胶泥由环氧树脂水乳液、固化催化体系及填料等三部分组成,具有无毒,不燃等性能。使用时先把乳化液与固化剂在拌料盘中混合搅匀,加入填料,再
The appearance defects of cement products, according to the provisions of national standards, and some can take appropriate repair measures to solve. In the past, we used cement mortar and epoxy-ethylenediamine to repair the material, but the former is easy to fall off and is not strong. The latter is toxic due to ethylenediamine, and workers are reluctant to use it. Later, through QC group activities, we applied the HS-812 epoxy resin water emulsion repair, achieved good results, and formulated the corresponding operating procedures. First, repair materials and preparation methods HS-812 epoxy resin water emulsion mud from the epoxy resin emulsion, curing catalyst system and filler, composed of three parts, with non-toxic, non-combustible and other properties. When using, mix the emulsion and curing agent in the mixing tray first, add the filler, and then
