防水边市场
Waterside Market
现在市场上有两种防水边，一种是我们通常说的防水边，双组份防水材料，操作时必须由专业人员操作，此种的防水边硬度大，耐磨损，抗酸碱、抗老化性能比较好，经久耐用。通常是以工程形式分包给专业的工程公司。工程费用较高。
There are two kinds of waterproof edge on the market now. One is waterproof edge, two component waterproof material, which we usually say. It must be operated by professional personnel when operating. This kind of waterproof edge has high hardness, wear resistance, good acid and alkali resistance, and good aging resistance, and is durable. It is usually subcontracted to professional engineering companies in the form of engineering. The engineering cost is high.
另一种“防水边”是与上述双组份防水边完全不同，是单组份，不需要现场临时混合，硬度、耐磨、抗酸碱等性能均不及双组份防水边。产品以成品形式出现。使用时，只需要揭掉防水边表层的防护膜，直接将防水边按压粘接到需要封堵的缝隙即可。但不能适应施工现场边缝宽展不匀，瓷片有残缺、破裂、损坏等情况。
Another kind of "waterproof edge" is completely different from the above two-component waterproof edge, which is single component and does not need to be temporarily mixed on site. Its hardness, wear resistance, acid-base resistance and other properties are not as good as the two-component waterproof edge. Products appear as finished products. During use, only the protective film on the surface of the waterproof edge needs to be removed, and the waterproof edge can be directly pressed and stuck to the gap to be sealed. However, it can not adapt to the uneven spread of edge joints, incomplete, cracked and damaged porcelain pieces on the construction site.
