金屬表面對环氧地坪塗料塗裝的影響

环氧樹脂自流平地坪由於其美觀，耐用，防塵，所以主要適用於對潔凈要求高的醫藥生產車間，電子廠房和辦公室等區域。环氧樹脂自流平地坪的美觀主要因為該环氧地坪材料具有優良的流平性，可以自己自動流平，所以平整度高，光澤度高。但在环氧自流平實際施工過程中，偶爾會出現环氧地坪發花的問題，原因主要是以下這些原因：
Because of its beauty, durability and dust-proof, epoxy resin self-leveling floor is mainly suitable for areas such as pharmaceutical workshop, electronic workshop and office which require high cleanliness. The beauty of epoxy resin self-leveling floor is mainly due to its excellent leveling property and self-leveling, so it has high smoothness and gloss. However, in the actual construction process of epoxy self-leveling, occasional flooring problems occur, mainly due to the following reasons: 1、表面有小氣泡，整體顏色深淺不一致，地坪局部出現發白。
1, there are small bu透水地坪bbles on the surface, the overall color is not consistent, and the floors appear white.
這主要是因為环氧自流平的材料消泡能力差，可選擇更強的消泡劑進行消泡處理，同時可以調整填料和活性稀釋劑的比例，減少填料，增加火星稀釋劑；再者選擇黏度小，但固化時間長的固化劑。
This is mainly due to the poor defoaming ability of epoxy self-leveling materials, so stronger defoamers can be selected for defoaming treatment. At the same time, the proportion of fillers and active diluents can be adjusted to reduce fillers and increase Mars diluents; furthermore, curing agents with low viscosity but long curing time can be印花地坪 selected.
2、出現局部顏色不一。
2, the local color varies.
环氧樹脂自流平材料配置時使用雜牌樹脂，導致對顏料分散系統造成幹擾。
When epoxy resin self leveling material is used, the use of miscellaneous resin will cause interference to the pigment dispersing system.
3、灰色的材料容易發花
3, grey materials are easy to flower.
顏料中鈦白比較重，碳黑最輕，這導致在配置灰色的材料時，兩種顏色顆粒由於重量的原因出現分層。一般要求一份黑他碳需要一分助劑，大約兩分环氧和兩份活性稀釋劑來配制色漿，一般研磨三遍以上。
Titanium dioxide is heavier and carbon black is lightest in the pigments, which results in the layering of two color grains due to weight. Usually one black carbon needs one assistant, about two epoxy and two active diluents to prepare color paste, generally grinding more than three times.
