影响环氧砂浆地坪固化时间的因素
影响环氧砂浆地坪固化时间的因素:环氧砂浆地坪的种类:在相同的固化条件下,环氧砂浆地坪漆涂料的类型不同,固化速度有很大的差别。挥发性油漆固化快,油性漆固化慢。固化的温度和湿度:当温度过低时,溶剂挥发和反应时间慢,漆膜就难以固化;提高温度,能加速溶剂挥发和水分蒸发,加速涂层氧化反应和热化学反应,涂层固化速度加快。但不能无限度地提高温度,因为温度与固化速度不是成正比的关系。固化温度过高时,固化速度没有明显地提高,反而会使漆膜发黄或色泽变暗。空气中的湿度在45%-60%比较适合涂料的固化。湿度过大,涂层中的水分蒸发速度降低,溶剂挥发速度变慢,因而会减慢涂层的固化速度。环氧砂浆地坪漆涂层的厚度:
The factors affecting the curing time of epoxy mortar floor: the type of epoxy mortar floor: under the same curing conditions, the type of epoxy mortar floor paint coating is different, and the curing speed is very different. The volatile paint is cured quickly, and the oil paint is cured slowly. The curing temperature and humidity: when the temperature is too low, the solvent volatilization and the reaction time are slow, the paint film is difficult to solidify; increasing the temperature, can accelerate the solvent volatilization and water evaporation, accelerate the coating oxidation reaction and thermochemical reaction, and the coating solidify speed is quicker. But temperature can not be increased indefinitely, because temperature is not directly proportional to curing speed. When curing temperature is too high, the curing speed is not significantly improved, but it will make the paint film yellowed or darkened. The humidity in the air is more suitable for 45%-60% curing. When moisture is too large, the evaporation rate of the water in the coating decreases, and the evaporation speed of the solvent slows down, which slows down the curing speed of the coating.
