Before we talk about it, we must know the control of temperature on the quality of floor type. Temperature is inseparable from the construction of epoxy floor, especially in summer. In general, we advocate that the construction should be carried out above 5 C during the construction process.
It is believed that low temperature and ground temperature will seriously affect the curing of epoxy coatings, resulting in a decrease in the hardness, strength and glossiness of the coatings, and increase the possibility of dust contamination of the coatings; during construction, the relative humidity of the air should be less than 80%. Excessive humidity will cause the whitening and gloss of the coatings, and even lead to a serious phenomenon of stickiness and non-curing of the coatings.
Ground temperature should be higher than dew point temperature of more than 3 C, otherwise the ground is easy to dew, floor paint affects construction; when the ground temperature reaches 50 C in summer or higher?
1. Prevent construction in high temperature period as far as possible. Bifurcate construction in early and late periods can be selected. Before using various materials, group B should be fully mixed before mixing, then pour component A and B into mixing barrel and mix evenly according to proportion, and then pour quartz powder or powder into mixing evenly after ripening, and then apply after mixing evenly (strictly control the ripening time).
2. Summer high temperature surface painting will be more clear color, gray and blue appear more likely, should be fully mixed and then used.
3. When the temperature is too high in summer, the ingredients should be used as soon as possible, usually within 30 minutes to prevent the material from condensation.
4. Choosing Artificial Cooling Method
5. In order to ensure the relative humidity of the construction environment, the floor paint can be humidified manually at the construction site.
6. On site after construction, special care should be ensured to avoid shrinkage cracks of epoxy floor caused by excessive temperature.
