环氧地坪冬季施工註意事項

隨著冬季的到來，全國大部分地區氣溫的降低，空氣幹燥，使环氧地坪塗料難以施工，环氧地坪漆的施工溫度一般要求在5度以上，濕度要低於85%，否則不宜施工。而低於5℃，环氧地坪塗料的地面實際效果就比較難保證。國內北方地區的冬季，溫度在5℃以下是很常見的事情，那麼在這種环境下，环氧地坪的施工都會遇到哪些問題？
With the arrival of winter, the temperature of most parts of the country has dropped and the air is dry, which makes it difficult to construct epoxy floor coatings. The construction temperature of epoxy floor coatings is generally required to be above 5 degrees and the humidity is below 85%, otherwise it is not suitable for construction. And below 5 degrees, the actual effect of epoxy floor coating is difficult to guarantee. In the winter of northern China, the temperature below 5 is very common, so in this environment, what problems will be encountered in the construction of the floor? 首先來瞭解一下為什麼低溫环境下环氧地坪會難以施工：
First of all, to understand why the epoxy floor in low temperature environment will be difficult to construct:
1、減慢塗料反應。
1, slow down the paint reaction.
雙組分的环氧地坪塗料施工，需要現場將甲、乙組分按比例混合，攪拌均勻，讓雙組分充分反應，這樣才能保證地坪的效果。但如果溫度低於5℃，反應將會降低或減緩，這會嚴重影響地坪塗料的固化性能。而固化性能的降低，將導致塗膜表面幹得很慢，會增加塗膜被灰塵，雜物，或者昆蟲（蒼蠅、蚊子）污染的可能。
In the construction of two-component floor coating, it is necessary to mix the components A and B proportionally in the field, mix evenly, and make the two components fully react, so as to ensure the effect of the floor. However, if the temperature is lower than 5 C, the reaction will be reduced or slowed down, which will seriously affect the curing performance of floor coatings. Decreased curing performance will result in a slow drying of the film surface, which will increase the possibility that the film will be contaminated by dust, debris, or insects (flies, mosquitoes).
2、黏度成倍增長。
2, viscosity increases彩色沥清地坪 exponentially.
無溶劑的自流平塗料靠流平性保證地坪的平整度。但低溫下，地坪塗料的黏度會成倍增加，流平性能將降低。而不靠流平性的塗料，刮塗時會因為流動、流平性能變差，而出現鏝刀痕的缺陷。
Solventless self leveling coatings ensure smoothness of the floor by leveling. But at low temperatures, the viscosity of the floor coating will increase exponentially and the leveling performance will be reduced. However, without leveling coating, the defect of trowel marks will appear when scraping because of the poor flow and leveling performance.
3、降低塗膜質量。
3, reduce the quality of coating.
由於固化反應減慢，或者完成不能固化，塗膜的強度、硬度、耐磨性都將會降低，而且會更容易出現地坪脫離等問題，嚴重的影響环氧地坪的使用壽命。
The strength, hardness and wear resistance of the coatings will be reduced due to the slowdown of curing reaction or the failure of curing, and the problems of floor detachment will occur more easily, which will seriously affect the service life of epoxy floor.
根據以上幾個問題，我們可以這樣來解決：
According to the above questions, we can solve this problem.
1、隔開低溫時段：环氧地坪施工時，在白天的上午10點至下午3點內施工，盡量隔開低溫時段，盡可能的減少低溫的影響。
1. Separate the low temperature period: When constructing the epoxy floor, it should be constructed from 10:00 a.m. to 3:00 p.m. in the daytime, and try to isolate the low temperature period to minimize the impact of low temperature.
2、增加室溫：可以把室內的溫度提高，也可以在冬季進行环氧地坪漆施工，北方有條件的可以在环氧地坪漆施工前和施工的過程中供應暖氣。
2. Increase room temperature: you can raise the indoor temperature, you can also carry out the construction of epoxy floor paint in winter. Northern conditional can supply heating before and during the construction of epoxy floor paint.
3、添加溶劑：為瞭解決地坪漆在低溫下黏度大，缺乏流動性難攪拌，可添加小於5%的揮發速率較快的溶劑，如丙酮、醋酸乙酯、醋酸丁酯等，這樣可以增加地坪漆的流動性。
3. Solvent addition: In order to solve the problem of high viscosity at low temperature and lack of fluidity and difficult stirring, solvents with less than 5% volatilization rate can be added, such as acetone, ethyl acetate, butyl acetate and so on, so as to increase the fluidity of floor paint.
4、施工時一定要攪拌均勻，由於低溫會使固化時間變長，所以要確定漆已經幹透才能施工第二道漆。
4. Must mix evenly during construction, because low temperature will make solidification time longer, so it is necessary to make sure that the paint has dried thoroughly before the construction of the second paint.
為瞭在低溫环境下同樣能達到理想的施工效果，避免漆膜弊端的出現，還有很多方面需要我們去註意：
In order to achieve the same ideal construction effect in low temperature environment and avoid the appearance of drawbacks of paint film, we need to pay attention to many aspects:
1、冬季施工要註意：首先緊閉門窗，這樣一方面可以保證室內溫度，另一方面也可以避免室外風沙吹刮到未幹的地面上，出現毛糙不平整的現象。等塗料充分幹燥後，再敞開門窗通風，並註意把握時間。
1. Winter construction should pay attention to: first, close doors and windows, so that on the one hand can ensure indoor temperature, on the other hand, can also avoid outdoor wind and sand blowing to the dry ground, rough and uneven phenomenon. When the paint is fully dried, open doors and windows to ventilate and pay attention to time.
2、油工在噴刷各種塗料時，應嚴格按照產品說明中的溫度和濕度塗刷，塗施工环境的溫度不能低於5℃，濕度不宜大於80%。其中，常用的混色塗料施工時环境溫度應在0℃以上，清漆施塗時的环境溫度則不得低於8℃。
2. Oil workers should brush all kinds of coatings strictly according to the temperature and humidity in the product description. The temperature and humidity of the application environment should not be lower than 5 C and should not be greater than 80%. Among them, the ambient temperature of the commonly used mixed color coatings should be above 0 while the ambient temperature of varnish should not be below 8.
3、在實色漆工藝中如使用膩子或水灰，不能刮塗過厚，並且必須做到幹透後徹底打磨，達到：地面平整、用指甲扣不掉漆、手感光滑，否則會導致開裂、脫落現象出現。
3. If putty or water ash is used in solid-color paint process, it should not be scratched and painted too thick, and it must be thoroughly polished after drying to achieve: flat ground, nail buckle can not remove paint, smooth handle, otherwise it will lead to cracking and peeling phenomenon.
4、在塗刷各種塗料時，應嚴格按照產品說明中的要求施工，嚴格控制稀釋比例。
4. When painting all kinds of coatings, we should strictly follow the requirements of the product description and strictly control the dilution ratio.
5、冬季寒冷，工人習慣抽煙或生火取暖，這個時候一定要註意安全意識，不要再塗料堆放地附近生火或吸煙，否則一旦引燃，桶裝塗料可能會引發爆炸。
5. In cold winter, workers are accustomed to smoking or lighting a fire for heating. At this time, they must pay attention to safety awareness and stop lighting a fire or smoking near the place where the paint is stacked. Otherwise, once ignited, the barreled paint may cause explosion.
6、嚴禁一次性厚塗，防止噴塗過厚導致出現發白、起泡和針孔。
6, strictly prohibit one-off thick coating to prevent excessive spraying resulting in whitening, foaming and pinholes.
7、基材施工前必須進行有效的封閉處理，避免出現漆膜發白、脫落等弊端。
7, the substrate must be effectively sealed before construction to avoid whitening and falling off.
8、嚴禁采用超量使用固化劑來提高幹燥速度，否則容易導致漆膜過脆引起開裂。不建議使用幹速過快的固化劑。在氣溫較低時，有些廠傢過分追求幹速，而使用幹速過快的固化劑，這將會導致漆膜出現開裂、陰陽面、失光等漆膜弊端。
8. It is strictly forbidden to use excessive curing agent to improve drying speed, otherwise it is easy to cause the film to be too brittle and crack. It is not recommended to use fast curing agents. When the temperature is low, some manufacturers excessively pursue drying speed and use curing agent with too fast drying speed, which will lead to film cracking, Yin and Yang surface, loss of gloss and other drawbacks.
9、請配套使用產品，隨著氣溫變冷，註意冬用稀釋劑配套使用，減少因配套不良導致的不必要損失。
9. Please use the matching products. As the temperature becomes colder, pay attention to the matching use of winter diluents to reduce unnecessary losses caused by poor matching.
10、使用廂式貨車運輸施工材料、水性塗料、膠類，應用保溫材料封包後運輸避免凍壞。水性塗料、膠類應存放在溫度較高的房間，避免放在陽臺、北向房間防止凍壞。
10. Use Van trucks to transport construction materia印花地坪ls, water-borne coatings and glues. Use thermal insulation materials to avoid freezing damage. Water-borne coatings and glues should be stored in rooms with high temperatures. Avoid putting them on balconies and northbound rooms to prevent frost damage.
傳統觀念認為的冬季不宜施工，其實是因為有許多不便，並不是不能施工，我們在施工前搞清楚會遇到的問題，從各個方面進行預防，把握好尺幅，冬季施工反而會有意想不到的效果。
The traditional concept that winter construction is not suitable, in fact, because there are many inconveniences, not can not be constructed, we will find out the problems encountered before construction, from all aspects of prevention, grasp the scale, winter construction will have unexpected results.
