摘要：水性丙烯酸聚硅氧烷防腐涂料表面在使用涂刷的过程中容易出现流挂现象，这样现象的出现为装饰效果和保护性能造成了很大的影响。怎样才能够防止这样现象的出现，并且如何解决？ Abstract: water-based acrylic polysiloxane anti-corrosion coating surface in the process of using besmear brushs prone to flow phenomenon, the emergence of this phenomenon is adornment effect caused great influence and protection performance. How to prevent the occurrence of this phenomenon, and how to solve? 水性丙烯酸聚硅氧烷防腐涂料流坠的出现 所谓流坠就是水性丙烯酸聚硅氧烷防腐涂料是施工的过程中基层表面出现下滴、下垂、漆膜不平等的现象，这些都可称之为油漆流坠。 So-called flow falling is water-based acrylic polysiloxane anticorrosive coatings is appeared in the process of construction at the grass-roots level surface drip, drooping, paint film inequality, all of these can be called the paint flow 水性丙烯酸聚硅氧烷防腐涂料流坠的原因 一般这样现象的出现一般有几种原因：由于产品配料太稀，附着能力差所致。这样在重力的作用下，无法附着到基面上就产生了流淌现象。当然也有因为涂刷或喷涂太厚，漆膜过重出现下坠。施工温度过低，无法干燥出现下坠，或者部分产品不达标，基面有油、水等污物与水性丙烯酸聚硅氧烷防腐涂料不相容影响黏结效果造成漆膜下坠。 Generally the emergence of a general there are several reasons for this phenomenon: the product is too thin, ingredients caused by poor adhesion ability. So under the action of gravity, not attached to the base is produced on the surface of flow phenomenon. Also, because the coating or coating is too thick, paint film is overweight appear down. Construction temperature is too low, can't appear dry down, or part of the product is not up to standard, the base has the dirt such as oil, water and water-based acrylic polysiloxane anticorrosive coatings film drop incompatible influence bonding effect. 水性丙烯酸聚硅氧烷防腐涂料流挂现象再解决 流挂现象的解决一般并没有更好的办法，只能用砂纸或者其他工具将出现问题的基面进行打磨，之后再重现涂刷。那么，为了解决这类问题就只能从根本上避免出现。首先要选择好质量达标的产品，之后再稀释的过程中，一定要控制水量，调试到适合的黏度之后再进行涂刷。在涂刷前，要将基面处理干净，确保表面平整、光洁，清楚表面油、水等污物。并且在环境温度能给达到使用标准的前提下进行涂刷。涂刷的时候工艺程序要按照先竖向、横向、斜向，最后再竖向将水性丙烯酸聚硅氧烷防腐涂料理平，使漆膜厚度均匀一致。最后在喷漆的时候要注意喷枪移动速度及距离物体的远近要控制均匀，这样才能确保漆膜形成均匀，厚薄一致。确保漆膜的正常形成，也就不会出现流坠的现象了。 Flow phenomenon generally no better solution, can only use sand paper or other base level of grinding tool will appear problem, and then is besmear again. So, in order to solve this kind of problem can be fundamentally avoided. First should choose good quality products, then the process of dilution, must control the amount of water, debugging to suitable viscosity before coating. Before coating, base should be clean and ensure smooth, bright and clean, clear surface oil, water and other contaminants. And in the environment temperature can be used to achieve the standard under the premise of coating. Besmear brushs the process at the time of vertical, horizontal, oblique, according to the first and then the vertical waterborne acrylic polysiloxane anticorrosive coating will smooth out, make the film thickness uniformity. Finally in spray painting must pay attention to the spray gun movement speed and distance of objects near and far to uniform control, to ensure uniform film formation, thickness. Paint film to ensure normal form, but also won't appear the phenomenon of flow falling. |
