| 气象局连续几天发布高温橙色预警，温度高达35摄氏度，给人们日常生活带来极大的不便。尤其对于环氧地坪的施工人员来说，夏季过高的温度，会给施工带来很多麻烦。在这之前，我们要知道温度和湿度对环氧地坪质量的控制。 The Meteorological Bureau issued a high temperature orange warning for several days, the temperature as high as 35 degrees Celsius, bring great inconvenience to people's daily life. Especially for the workers of epoxy floor, the high temperature in summer will bring a lot of trouble to the construction. Before that, we need to know the temperature and humidity control over the quality of the epoxy floor. 一般情况下施工过程中建议在温度在5℃以上进行施工，认为气温及地面温度过低会严重影响环氧涂料的固化，导致漆膜硬度、强度、光泽度等性能下降，并增加了漆膜受灰尘污染的可能性。 Generally speaking, it is suggested that the construction should be carried out at temperatures above 5 C. It is considered that the low temperature and ground temperature will seriously affect the curing of epoxy coatings, resulting in the decrease of hardness, strength and glossiness of the coatings, and increasing the possibility of dust contamination of the coatings. 施工过程中空气相对湿度应小于80%，湿度过高会使漆膜表面发白、失光，甚至发生漆膜发粘、不固化的严重现象。 The relative humidity of the air should be less than 80% during the construction process. Excessive humidity will make the surface of the paint film white and dull, and even the film will become sticky and not solidified. 1 固化问题 1 curing problem 这一问题在环氧地坪涂料的施工中常常出现，这是因为夏季雨水多，湿度大，造成固化剂里的胺析出而产生白雾集结，在涂抹表层。 This problem often occurs in the construction of epoxy floor coatings, which is due to the summer rains, high humidity, resulting in the precipitation of amines in the curing agent and white fog agglomeration in the coating surface. 所以施工前，要对环境湿度进行测量，如果相对湿度大于或等于8%，不宜进行施工。 Therefore, before the construction, to measure the environmental humidity, if the relative humidity is greater than or equal to 8%, not suitable for construction. 固化过快的话，这是因为施工环境温度过高，这时固化剂的比例就要相对的减少，或者尽量避免高温时段施工，可以采用早晚时段分叉施工 If curing is too fast, it is because the construction environment temperature is too high, then the proportion of curing agent will be relatively reduced, or as far as possible to avoid high temperature construction, can be used in the morning and evening period of bifurcation construction 2 针孔问题 2 pinhole problem 环氧地坪完工干燥后，在涂膜的表面出现许多针孔，这会严重影响地坪表面的亮度和装饰的效果。 After the epoxy floor is finished and dried, many pinholes appear on the surface of the coating film, which will seriously affect the brightness of the floor surface and decorative effect. 造成这一弊端的原因一是因为涂膜过厚，二就是因为夏季温度过高，涂膜干燥过快，导致地坪表面出现针孔。 One reason for this is that the film is too thick, and the other is because the summer temperature is too high, the film drying too fast, resulting in the surface of the floor pinholes. 3 环形山孔、凹陷问题 3 ring-shaped holes and holes 在环氧地坪施工中，出现的环形山孔和凹陷的主要原因是环氧地坪基层有油污，充填料分配不均等。 During the construction of epoxy floor, the main reasons for the annular holes and depressions are the oil pollution in the base of epoxy floor and unequal distribution of filling materials. 所以，在施工中，一是要处理好基层问题，二是在进行配料时，施工设备和工具要保持清洁，注意清洁避免杂质混入。 Therefore, in the construction, one is to deal with the grass-roots problems, the other is in the batching, construction equipment and tools to keep clean, pay attention to cleaning to avoid impurities mixed. 夏季温度过高时，配料后应尽快使用，一般再30分钟内使用完毕，以避免材料凝结。 When the temperature is too high in summer, the ingredients should be used as soon as possible, usually within 30 minutes to avoid condensation. |
