解讀环氧地坪漆施工失敗的原因及預防方法

一、起水泡原因：1）結構體地下層、水箱旁、底樓層或其它地面水氣濕度偏高；2）沒做防水處理或底漆封閉不良。預防方法：1、施工前先以水份計協助判斷；2、水份及水壓太高的地點須先做防水處理；3、選擇水性的环氧樹脂底漆。
The causes of blistering are as follows: 1) high moisture in the underground layer, near the water tank, bottom floor o印花地坪r other ground floor; 2) no waterproof treatment or poor sealing of primer. Preventive methods: 1. Use moisture meter to assist in judging before construction; 2. Waterproof treatment should be done in places with too high water content and pressure; 3. Selec环氧地坪t waterborne epoxy resin primer.
二、色差
Two, chromatic aberration
原因：
Reason:
1、环氧樹脂地坪塗料主劑沉淀，未充分攪拌均勻；
1. The main agent of epoxy floor coating is precipitated and not fully stirred uniformly.
2、倒料在地面上，與前接縫處之接觸時間過久；
2. The contact time between the material and the front joint is too long when the material is dumped on the ground.
3、塗層厚薄不均勻；
3. Coating thickness is not uniform.
4、施工中途斷料；
4. Material breakage during construction;
5、采用不同批號面漆。
5. Different batches of topcoats.
預防方法：
Prevention methods:
1、施工前主劑應先充分攪拌均勻；
1. The main agent should be fully stirred and evenly mixed before construction.
2、避免與前接縫處接觸間隔太久，盡可能整個操作線一起施工；
2. Avoid long contact interval with the front joint, and construct the whole operation line as far as possible.
3、盡量適用固定工具及加強施工人員施工熟練度；
3. Apply fixed tools as far as possible and strengthen construction skillfulness of constructors;
4、塗料須一次備足，防止斷料；
4. Coatings should be prepared at one time to prevent material breakage.
5、盡可能使用同一批號塗料。
5. Use the same batch of paint as far as possible.
三、火山口
III. craters
原因：
Reason:
1、下層有坑洞；
1. There are holes in the lower layer.
2、下層有油污；
2. Oil pollution in the lower layer;
3、塗料本身原因。
3. Reasons for paint itself.
預防方法：
Prevention methods:
1、施工前先用环氧批土把坑洞修補平後再進行施工；
1. Before construction, epoxy batch earth is used to repair and flatten the pit before construction.
2、將下層油污清除幹凈；
2. Clean up the oil pollution in the lower layer.
3、先用合適的塗料。
3. Use appropriate coatings first.
四、發白
Four, whitening
原因：
Reason:
1、冬天油漆反應速度過慢，用硬化劑與空氣反應產生白霧狀；
1. In winter, the reaction speed of paint is too slow, and the hardener reacts with air to produce white fog.
2、在低溫多濕之場合施工；
2. Construction at low temperature and humidity.
3、施工後遭水侵入。
3. Water intrusion after construction.
預防方法：
Prevention methods:
1、選擇適當硬化劑；
1. Selecting appropriate hardener;
2、避免低溫多濕條件施工，不得已時采取加溫除濕措施，如空調加溫降濕，暖風機加溫；
2. In order to avoid construction under low temperature and humidity conditions, heating and dehumidification measures should be taken when necessary, such as air conditioning heating and dehumidification, and heater heating.
3、避免施工後有水侵入。
3. Avoid water intrusion after construction.
