How to deal with the resurgence of floor tiles
First, try to reduce the temperature difference between indoor and outdoor. Before the "cold tail and warm head" is about to regain its moisture, use heat source equipment such as heaters and electric ovens to heat the room so that the indoor temperature is equal to or slightly higher than the outdoor temperature.
Second, try to isolate the invasion of warm and humid air and pay close attention to the weather changes. Once the wind turns from north to south, doors and windows should be closed in time, and doors of indoor wardrobes and kitchen cabinets should be closed to reduce the entry of warm and humid outdoor air.
Third, put some hygroscopic and hygroscopic substances indoors. It is more economical and ideal to use quicklime (massive lime). After the lime melts, it will absorb the water vapor in the air, release heat, and raise the temperature of the room.
The fourth is to use equipment for dehumidification, and the air conditioner with dehumidification function should be turned on immediately; If possible, you can also use a dehumidifier (dehumidifier) to filter the indoor air and "dehydrate" it while continuing to heat the room.
Fifth, articles that are afraid of being affected with damp and prone to mildew should be sealed and stored before the spring to isolate the air. If you can put desiccant, the effect will be better.
Sixth, the cold and warm air currents frequently meet in spring, and there is a degree of advance and retreat. After the "resurgence" day, if the weather turns better (to the north wind), you should immediately open the window to ventilate and blow away the moisture; In sunny weather, dry clothes and bedding at home and keep them dry.
What is the reason why floor tiles are moisture-proof?
1, seasonal factors
The moisture regain of ceramic tiles is that humid air with high temperature (relative humidity above 90%) meets the ground with low temperature, and the ground is smooth and does not absorb water, which is easy to produce condensed water on the ground (usually when the temperature is about 2℃). This happens mostly in the rainy season, with much rain, high temperature and high humidity. Once the climate turns fine and dry, the phenomenon of moisture regain can be eliminated.
2. Soil factors
The moisture regain of ceramic tiles is that the moisture in the foundation soil under the floor cushion rises due to capillary action, and the water vapor permeates upward, which makes the floor material wet and aggravates the deterioration of the whole indoor humidity. This kind of situation often happens all the year round and is difficult to deal with. In addition, there are reasons such as poor outdoor drainage and poor indoor ventilation. The surface layer in most parts of South China is mostly clay and loam. Capillary water level of clay can rise to 2 ~ 2.5m, and loam can reach1~1.3m.. When building materials with poor compactness are used as indoor floors, the capillary action will be enhanced, and the phenomenon of ground moisture regain will be more serious.
In wet season, you can buy 10- 15 kg of quicklime. As for the container, cover it and put it under the bed or in the corner. When the weather is very wet, open the lid and close the doors and windows. But you can open the necessary transom. As quicklime is a good desiccant, it can absorb the water vapor in the air and convert it into calcium hydroxide, thus keeping the indoor air dry.
