施工前环氧樹脂地坪漆結晶怎麼辦？

什麼是結晶？常溫條件下，环氧樹脂地坪漆是無色透明液體狀態，可流動。當出現顏色灰暗、出現自由浮動的晶體、晶體團塊、或出現類似固化的硬塊的時候，我們稱之為結晶現象。
What is crystallization? Under normal temperature, epoxy floor paint is colorless, transparent and liquid. Crystallization occurs when gray colors, free-floating crystals, crystal clumps, or solidification-like lumps occur.
結晶的表現
Crystallization performance
液態环氧樹脂地坪漆初期結晶顆粒一般會出現在容器底部，隨著時間的推移，這些具有沙狀晶體結構的結晶顆粒逐漸增多，並聚集在一起，直到完全硬化為止。
The initial crystalline particles of liquid epoxy floor paint usually appear at the bottom of the container. With the passage of time, these crystalline particles with sandy crystal structure gradually increase and gather together until fully hardened.
結晶的原因
Causes of crystallization
首先是环境變化影響。在常溫條件下，液態环氧樹脂的熔點溫度是45-50°C，當外在溫度降低時，分子鏈活躍度降低，容易發生結晶。
The first is the impact of environmental change. At room temperature, the melting point temperature of liquid epoxy resin is 45-50 degrees C. When the external temperature decreases, the activity of molecular c透水地坪hain decreases and crystallization occurs easily.
其次环氧樹脂自身高純度，低粘度，雜質多。外在环境溫度一變化，冷熱交替，就易產生結晶現象。
Secondly, epoxy resin has high purity, low viscosity and many impurities. External environment temperature changes, cold and heat alternate, it is easy to produce crystallization phenomenon.
解決方案
Solution
1、管控好环氧樹脂地坪漆儲存环境的溫度。通常儲存溫度應高於40℃，才能防止出現結晶化現象。高於25℃，可降低結晶風險，但需避免溫度波動過大。
1, control the temperature of epoxy resin floor paint storage environment. Usually, the storage temperature should be higher than 40 C to prevent crystallization. Higher than 25 C can reduce the risk of crystallization, but avoid excessive temperature fluctuations.
2、一旦發生結晶現象，可在50℃环境條件下保持幾小時，即可重新融化环氧樹脂环氧地坪漆，在加熱時需要不斷攪拌使其復原。
2. Once crystallization occurs, it can be maintained for a few hours at 50 C. The epoxy floor paint can be melted again, and it needs to be stirred continuously to recover when heated.
3、對於儲存环境濕度的要求，一般在相對濕度50%以下，同時對包裝的密封性需嚴格要求，避免吸水導致結晶。
3. For the storage of environmental humidity requirements, generally less than 50% of the relative humidity, while packaging tightness needs to be strictly required to avoid water absorption leading to crystallization.
4、使用低結晶或高粘度的环氧樹脂环氧地坪漆，這種方法的缺點是黏度略高，或者在地坪漆裡添加其他類型的环氧樹脂，降低純度。
4. Use low-crystalline or high-viscosity epoxy floor paint, this method has the disadvantage of slightly higher viscosity, or in the floor paint to add other types of epoxy resin, reduce purity.
环氧地坪漆結晶會造成施工後的地坪鼓裂、分層等質量問題，十分影響美觀，特別是在氣溫低的冬季，這種情況出現的可能性更大。所以認識並解決地坪結晶問題，是施工方和甲方客戶都需重視的問題。
Epoxy floor paint crystallization will cause quality problems such as floor cracking, delamination and so on after construction, which will greatly affect the aesthetics, especially in winter when the temperature is low印花地坪. This situation is more likely to occur. Therefore, understanding and solving the problem of floor crystallization is a problem that the construction side and the first party customer need to pay attention to.
