1. Temperature and humidity measurements, dew point determination
Monitoring the temperature and humidity of the instrument temperature and humidity measurement table, measuring the wet and dry soaking temperature of the dry humidity control, electronic temperature and humidity continuous recorder. When measuring, the meter should be installed in the collection of hot, cold and average area of data, but not in direct sunlight, wind, heat radiation, heating or ventilation ducts or other parts of the average impact of the epoxy floor paint.
Previously used wet bulb thermometer to measure the temperature and relative humidity, is composed of two identical mercury (or ethanol) thermometer, one of which has two layers of gauze (or cotton), gauze dipped into the bottom of the bottle filled with water, the thermometer The reading is the wet bulb temperature and the other thermometer reads the dry bulb temperature. According to the dry and wet bulb temperature difference, in the special table to detect the relative humidity in the air.
At present, the market has measured the ambient temperature, relative humidity of the measurement table sold, can be directly measured temperature and humidity, and the corresponding table 5-15 corresponding to the temperature and relative humidity point, find the dew point temperature. The surface temperature of the coated surface should be higher than the dew point of 3 ℃ before coating.
Without the above conditions, you can use a damp cloth in the already clean surface coated with a very clear layer of thin water, evaporated in 15min removed, can be considered to meet the dew point requirements.
2. Other requirements and inspection items
Due to the construction of the floor requires a clean and closed coating environment, any details of the negligence may cause defects or rework, resulting in loss, and therefore in the approach before construction to check the following aspects:
① whether the doors and windows have been intact, the construction site can be closed, roof, water pipes and other leaks hidden;
② avoid cross-operation, the construction of moderate ventilation, but should prevent the sand, dust and other surrounding pollution;
③ lighting, electricity and other facilities are available, for their own, should be planned and ready;
④ pay attention to the weather forecast, the proposed weather conditions during construction is appropriate.
