近幾年，無錫環氧地坪在我國有了很大的發展，尤其在生產車間、超市、地下車庫、展館、教室、實驗室等場合得到普遍使用。環氧樹脂地坪潔凈度高、耐磨、耐腐蝕、抗沖擊、無接縫、質地堅實、保養方便、維護費用低且具有很好的裝飾效果。當然，保證這些優點的體現，需要進行全過程的質量控制，從基材質量、基面處理到涂裝環境、涂裝方案，都要結合環氧樹脂地坪的施工過程及特點，進行相應的質量控制。環氧地坪施工要注意哪些要點?

In recent years, epoxy flooring has made great progress in China, especially in the production workshop, supermarket, underground garage, exhibition hall, classroom, laboratory and other occasions have been widely used. Epoxy floor has high cleanliness, wear resistance, corrosion resistance, impact resistance, seamless, solid texture, easy maintenance, low maintenance cost and good decorative effect. Of course, to ensure these advantages, it is necessary to control the quality of the whole process, from the quality of the base material, the treatment of the base surface to the painting environment and the painting scheme, combining with the construction process and characteristics of the epoxy floor, to carry out the corresponding quality control. What points should be paid attention to in the construction of epoxy floor? 

基材質量

Substrate quality

基材也就是環氧施工的基礎層，通常以混凝土地面為主，地面狀況對終的環氧地坪工程質量影響很大，如果地面狀況達不到要求，環氧工程就很難做好，而且在環氧地坪使用過程中常會出現起殼、脫落、起泡等現象。因而，良好的基材狀況是保證環氧地坪工程質量的前提，有些基材不符合環氧環氧地坪涂裝的要求，則不應選用此地面裝飾方式。一般環氧環氧地坪對混凝土基材的要求如下：

The base material is the foundation layer of epoxy construction, which is mainly concrete floor. The ground condition has a great influence on the quality of the final epoxy floor project. If the ground condition does not meet the requirements, it is difficult to do well in the epoxy floor project, and in the process of using the epoxy floor, there are often phenomena such as shelling, falling off and foaming. Therefore, good base material condition is the premise to ensure the quality of epoxy flooring project. Some base materials do not meet the requirements of epoxy flooring painting, so this floor decoration method should not be selected. The General requirements of epoxy flooring for concrete substrates are as follows:

1、混凝土要求平整密實，強度要求不低于C20;若強度太差，必然影響涂層耐壓、抗沖性能及耐久性。

1. Concrete should be flat and compact, and its strength should be no less than C20. If the strength is too poor, it will inevitably affect the compressive, impact resistance and durability of the coating.

2、地面平整度一般要求在2m范圍內落差不大于2mm好用抹光機抹平并收光);如落差較大，則地坪涂層需加厚以減小落差。

2. Ground smoothness generally requires a drop of less than 2 m m within the range of 2 m to be smoothed and glowed by a polisher. If the drop is large, the coating on the ground needs to be thickened to reduce the drop.

3、如需涂裝的地面處于底層，地下水位較高，則混凝土底層應做好防水處理，避免地下水上升形成的蒸汽壓頂起地坪涂層而引起起泡、起殼現象。

3. If the ground to be coated is at the bottom and the groundwater level is high, the concrete bottom should be waterproof, so as to avoid the bubbling and shelling caused by the vapor pressure caused by the rise of groundwater.

4、新建混凝土干燥至少3周以上，含水率不高于6%，且在養護干燥過程中避免局部淋雨及地面積水，否則易引起局部混凝土水分含量超標。

4. New-built concrete is dried for at least 3 weeks, and its moisture content is not higher than 6%. In the process of curing and drying, local raining and surface water should be avoided. Otherwise, local concrete moisture content will easily exceed the standard.

5、樓板、鋼筋混凝土梁等構件上的細石混凝土找平層強度不應低于C20，厚度不低于0mm。

5. The strength of fine stone concrete leveling layer on floor, reinforced concrete beam and other components should not be lower than C20, and the thickness should not be less than 0 mm.

6、對損壞的混凝土表面修補或找平時，應采用強度等級不小于C20的細石混凝土，找平厚度不應小于30mm;需用水泥砂漿找平時，應先涂一層混凝土界面處理劑，再按設計厚度找平。當施工過程不宜進行上述操作時，可采用樹脂砂漿或聚合物水泥砂漿找平。

6. For repairing or leveling damaged concrete surface, fine stone concrete with strength grade not less than C20 should be adopted, leveling thickness should not be less than 30mm; for leveling with cement mortar, a layer of concrete interface treatment agent should be coated first, and then leveling according to the design thickness. Resin mortar or polymer cement mortar can be used to leveling when the above operation is not suitable in the construction process.

7、細節部位，如落水管周圍、門檻處等混凝土應平整，棱角應平直。

7. The details, such as the concrete around the downspout pipe and the threshold, should be level and the edges and corners should be straight.

8、大面積混凝土基層應根據基材狀況切割合理伸縮縫留待地坪涂裝時處理，為保持地面美觀，盡量將伸縮縫隱蔽在隔斷下，若不行，則在環氧地坪施工時留縫，然后用彈性膠灌縫。

8. Large area concrete base should cut reasonable expansion joints according to the condition of base material and leave them to be treated when the floor is painted. In order to keep the ground beautiful, the expansion joints should be concealed under the partition as far as possible. If not, the expansion joints should be retained during the construction of epoxy floor and then filled with elastic glue.

基面處理

Base surface processing

基面處理不是簡單的“鏟一鏟，掃一掃，去除灰塵”，而是去除浮層及污物，提高地面整體平整度，獲得均一的粗糙表面以利于涂層附著。科學的地坪涂裝十分重視基材處理，并采用專業的處理機械進行處理。

Base surface treatment is not simply "shovel one shovel, sweep one shovel, remove dust", but to remove floating layer and dirt, improve the overall smoothness of the ground, obtain uniform rough surface to facilitate coating adhesion. Scientific floor coating attaches great importance to the treatment of base materials and adopts professional processing machinery to deal with them.

1、使用打磨機進行整體打磨，清除表面水泥浮漿或其他粘附物，將表面打磨粗糙。

1. Use a grinder for overall grinding, remove surface cement slurry or other adhesives, and grind the surface roughly.

2、采用吸塵器全面吸塵處理干凈。

2. Use a vacuum cleaner to clean up.

3、邊緣作重點人工打毛處理。

3. The edge work should focus on manual wool beating.

4、對地面進行檢查，如有油漬，用清潔劑進行除油清洗;如有局部潮濕的地面，需要進行烘干。

4. Check the ground. If there is oil stain, clean it with detergent. If there is local damp ground, it needs to be dried.

5、對于裂縫和小坑等，用樹脂砂漿預先補平;對于伸縮縫，用切割機切成0.5cm×0.5cm凹槽，再用柔性環氧樹脂砂漿進行平整處理。

5. For cracks and pits, resin mortar is used to pre-flatten them; for expansion joints, 0.5 cm * 0.5 cm grooves are cut by cutting machine, and then smoothed with flexible epoxy mortar.

6、對于舊漆地面，如舊漆層附著不牢，需采用地面銑刨機整體去除舊漆層，1mm厚度以下舊漆層可采用金剛切削刀處理。

6. For the old lacquer floor, if the old lacquer layer does not adhere well, the whole old lacquer layer should be removed by ground milling machine. The old lacquer layer below 1 mm thickness can be treated by diamond cutter.

涂裝環境

Painting environment

涂裝環境條件對地坪涂裝工程質量影響很大，只有在符合該要求的環境下施工，才能達到好的效果，目前常用的環氧地坪涂料對涂裝環境的要求一般如下：

The environmental conditions of painting have a great influence on the quality of floor painting project. Only when the construction is carried out in the environment that meets the requirements can the good results be achieved. The requirements of epoxy floor coating for painting environment are generally as follows:

1、涂裝環境溫度宜在10℃以上。地坪涂裝時一般都采用胺類固化劑，而環氧基與胺基反應在10℃以下很緩慢，5℃以下基本不反應。

1. The ambient temperature of painting should be above 10 C. Amine curing agents are generally used in floor coating, while the reaction between epoxy group and amine group is very slow below 10 C, and almost no reaction below 5 C.

2、基材表面溫度應高于涂裝環境露點3℃以上。若此條件達不到，一方面底材表面易結露，造成后道涂膜附著力不佳，另一方面，在涂漆后，漆膜未干前表面易結露(有一層水膜)，造成表面缺陷。特別是面漆，在此情況下，水氣易與漆中的胺類固化劑反應，造成涂膜表面光澤低、發霧、發白、發粘、油點、硬度低等缺陷，大大降低表面裝飾效果，嚴重時造成返工。

2. The surface temperature of the base material should be higher than the dew point of the coating environment above 3 C. If this condition is not reached, on the one hand, the surface of the substrate is easy to dew, resulting in poor adhesion of the back coating, on the other hand, after painting, the surface of the paint film is easy to dew before drying (there is a layer of water film), resulting in surface defects. Especially topcoat, in this case, water vapor is easy to react with amine curing agent in the paint, resulting in low gloss, fogging, whitening, sticking, oil point, low hardness and other defects of the film surface, greatly reducing the decorative effect of the surface, causing rework in serious cases.

3、無錫環氧地坪涂裝要求潔凈無塵的涂裝環境，在養護期間要求環境密閉等，也對工程質量影響很大。這包括施工場所是否有揚塵，施工場所是否會淋雨等。

3. Floor painting requires clean and dustless painting environment, and environmental sealing during maintenance, which also has a great impact on the quality of the project. This includes whether there is dust in the construction site, whether the construction site will be rained and so on.
