环氧地坪施工环境是最重要的,不管我們做什麼环氧地坪都要看好天氣,這將決定你的环氧地坪優劣性質。而在施工過程中,环境溫度和濕度往往是無法控制的,我們遇到天氣問題對环氧地坪的影響及解決方法,一定要將溫濕度引起的問題解決,不然地坪施工就很難成功瞭。
The construction environment of epoxy flooring is the most important. Whatever we do, we should keep a good view of the weather, which will determine the quality of your epoxy flooring. In the construction process, the en彩色沥清地坪vironmental temperature and humidity are often uncontrollable. When we encounter the impact of weather problems on the floor and the solutions, we must solve the problems caused by temperature and humidity. Otherwise, the floor construction will be difficult to succeed. 濕度對环氧地坪漆施工的影響:
Effect of humidity on epoxy floor paint Construction:
濕度,指的是空氣中水分的含量,一般用百分比來表示。如果有結露現象出現,說明空氣的相對濕度達到百分之百。根據环氧地坪漆施工要 求規定,當空氣相對濕度高於85%時,是不能進行环氧地坪漆施工的,因為容易出現泛白、裂紋等弊病。(濕固化型聚氨酯塗料除外)。濕度不僅影響环氧地坪漆 的施工,更是會影響地坪漆固化,濕度指數在過大的情況下才影響地坪塗裝,它的影響往往大於人們的想象。濕度過高,會引起塗裝表面結露,凝結的水會對固化劑 造成破壞引起塗膜發白、失光、發黏、回黏等現象,大大降低表面裝飾效果,嚴重時造成返工。特別無溶劑面漆,表幹時間一般較長,在塗漆後馬上下雨或在冬春季 的傍晚塗漆都是有危險的.但有時因為業主要求工期,理想的天氣條件不易出現,這時就需采取措施改善塗裝小环境瞭,如開啟空調加溫和抽濕。
Humidity refers to the moisture content in the air, usually expressed in percentage. If condensation occurs, the relative humidity of the air reaches one hundred percent. According to the construction requirements of epoxy floor paint, when the relative humidity of air is higher than 85%, the construction of epoxy floor paint can not be carried out, because it is prone to white, cracks and other defects. (except moisture curing polyurethane coatings). Humidity not only affects the construction of epoxy floor paint, but also affects the curing of the floor paint. When the humidity index is too large, it affects the floor paint. Its influence is often greater than people imagine. Excessive humidity will cause dew on the surface of the coating. Condensed water will destroy the curing agent and cause the phenomenon of whitening, loss of gloss, sticking and Re-sticking of the coating, which will greatly reduce the decorative effect of the surface and cause rework in serious cases. Especially solvent-free topcoat, the surface drying time is generally longer. It is dangerous to paint in the rain immediately after painting or in the evening of winter and spring. But sometimes, because the owner requires a time limit, ideal weather conditions are not easy to appear. At this time, measures need to be taken to improve the small environment of painting, such as opening air conditioning to warm and dehumidify.
溫度對环氧地坪漆施工的影響:
Influence of temperature on epoxy floor paint Construction:
环氧地坪漆施工环境的溫度我們是無法控制的,常看到規定說,环氧地坪漆不能在過低或過高的溫度下施工:
The temperature of epoxy floor paint construction environment is beyond our control. It is often seen that the regulations say that epoxy floor paint can not be constructed at too low or too high temperature:
溫度過低:許多雙組分的塗料在溫度低於5度的环境中很難進行固化反應,或者反應很慢,從而導致成膜的時間大幅延長,或者導致無法成 膜。無法固化就無法施工第2道工序,無法固化,就說明地坪無法完工。例如,塗膜幹得很慢,灰塵等雜物很容易污染其表面造成裝飾性效果變差;固化太慢還會影 響塗膜的性能,使其硬度降低、耐磨性變差等,直接就影響瞭地坪的使用壽命。
Low Temperature: Many two-component coatings are difficult to cure at temperatures below 5 degrees, or react very slowly, resulting in a considerable extension of film formation time or failure to film. Can not solidify can not build second processes, can not be cured, indicating that the floor can not be completed. For example, the film dries very slowly, dust and other impurities easily pollute its surface, resulting in poor decorative effect; curing too slowly will also affect the performance of the film, making it harder, wear resistance, etc., directly affecting the service life of the floor.
溫度過高:溫度高於30度,會導致塗料的稠度增加、幹結報廢,嚴重的話還會出現爆聚現象。導致工人還無法把桶內地坪漆施工完,环氧地坪漆就已經沒有用瞭。一般我們都采用少量多次的方法配漆,或者選用沸點高、揮發慢的稀釋劑調整。
Temperature is too high: temperature above 30 degrees, will lead to increased consistency of paint, dry end scrap, serious cases will also occur explosion phenomenon. The wor环氧地坪kers are unable to finish building the floor paint in the pail, so the epoxy floor paint is useless. In general, we use a small number of times to prepare paint, or choose a diluent with high boiling point and slow volatilization to adjust.
