混凝土界面剂 应用经验（二）
③瓷砖、钢铁上用的界面剂，最好用双组分的乳液型界面剂（环氧胶粘剂）、再用双组分水泥基粘结剂；直接用干粉水泥基界面剂不保险，一点受力可能使整块全掉，而且成本过高。
3. The interface agent used on ceramic tile and iron and steel is better to use two component emulsion type interface agent (epoxy adhesive) and then two component cement binder. Directly using dry powder cement based interface agent is not safe, and a little force may cause the whole block to fall off completely, and the cost is too high.
④现在薄抹灰外墙保温系统中使用的保温材料为膨胀聚苯板（EPS）或挤塑聚苯板（XPS）。EPS板一般直接用胶粘剂粘上墙，也有根据实际情况使用界面剂的；通常XPS板表面有一层致密的皮，粘结性很差，所以都要求使用改性聚合物乳液界面剂（水泥基界面剂便宜，但是喷到板面上后有起粉现象，不利于粘结，原因大概是由于涂层太薄，失水过快，水泥得不到充分水化导致），但如果粘结砂浆非常好，用毛面的挤塑板的话也可以不用界面剂。
(4) The thermal insulation materials used in thin plastering exterior wall insulation system are expanded polystyrene board (EPS) or extruded polystyrene board (XPS). EPS boards are usually glued to the wall directly with adhesive, and there are interfacial agents according to the actual situation. Usually, there is a dense layer of XPS on the surface of the board, so the adhesive is very poor. Therefore, it is necessary to use modified polymer emulsion interface agent (cement based interface agent is cheap, but after spraying on the surface of the board, there is a phenomenon of powder, which is not conducive to adhesion. The reason is that the coating is too thin, the water loss is too fast, the cement can not be fully hydrated, but if the bonding mortar is very good, the use of wool Extrusion board can also be without interfacial agent.
⑤XPS板乳液界面剂用几种乳液和水混合就行，一般多选择VAE乳液，与水拌和，吸水率一般的基层就少用点乳液，吸水率大的基层就多加点乳液，然后加少量消泡剂、纤维素醚之类的，要是需要放一段时间再加点防霉剂等。做出来之后的界面剂和水泥砂浆搅拌也叫界面剂，根据实际情况可用在其他方面。要注意的一点是，乳液加入量的浓度不要太高，否则界面剂结膜反而会起到相反的效果。
XPS plate emulsion interface agent with several kinds of emulsion and water mixed on the line, generally choose VAE emulsion, mixing with water, the water absorption of the general base of less use of point emulsion, water absorption of the base of the more emulsion, and then add a small amount of defoamer, cellulose ether and so on, if need to put a period of time add some mildew inhibitor. The interfacial agent and cement mortar mixing are also called interfacial agent, which can be used in other areas according to the actual situation. One thing to note is that the concentration of emulsion should not be too high, otherwise the interface agent will play the opposite effect.
