The humidity of the wall is more or less qualified, and now many small partners have higher and higher requirements for the decoration of the wall. A good wall can also make us look more comfortable and live more comfortably. Let's share how much humidity on the wall is qualified.
The wall humidity is more or less qualified 1 1, and the wall humidity is less than 50%.
2. The suitable temperature for mold growth is 28 degrees and the humidity is about 90%. Therefore, the humidity of the wall should not exceed 50%, otherwise it is easy to cause the wall putty to be moldy, leading to foaming at the grassroots level of the wall.
3, not only affect the appearance, but also affect human health, you can find a moistureproof company to deal with it.
According to the research of physiologists, when the indoor temperature is too high, it will affect the body's temperature regulation function. Due to poor heat dissipation, body temperature, vasodilation, pulse and heart rate will accelerate. If the indoor temperature is kept above 25℃ in winter, people will be tired, forced to feel dizzy and weak, slow thinking and poor memory. At the same time, due to the large temperature difference between indoor and outdoor, the human body is difficult to adapt and easy to catch a cold.
If the indoor temperature is too low, the metabolic function of human body will decrease, pulse, respiratory rate, subcutaneous vascular contraction, skin and pressure will be too high, and the resistance of respiratory mucosa will be weakened, which may lead to respiratory diseases. Therefore, the lower limit temperature and heat tolerance of scientists' "cold tolerance" are 1 1℃ and 32℃ respectively.
Pay attention to indoor temperature adjustment and indoor humidity. In summer, the indoor humidity is too high, which will inhibit the heat in the body, and people are also very stuffy and irritable. Indoor humidity will accelerate heat conduction in winter, making people feel cold and depressed. The indoor humidity is too low, because of the water loss of the upper respiratory mucosa, many people will feel thirsty, sore throat, hoarse voice, nosebleeds and colds. Therefore, experts believe that the upper limit of relative humidity should not exceed 80% and the lower limit should not be lower than 30%.
However, human sensation is not only affected by temperature or air humidity, but also the result of both. According to experiments, the most comfortable indoor temperature and humidity: the winter temperature is 18? 25℃, humidity 30%-80%, summer temperature 23-28℃, humidity 30%-60%.
In this range, those who feel comfortable account for more than 95%. In an air-conditioned room, people will feel most comfortable when the temperature is 19 to 24℃ and the relative humidity is 40-50%. If people who consider the activity of temperature and humidity think that the most suitable room temperature should be efficient. 18℃, the humidity should be 40% to 60%, and at this time, people's mental state is the clearest.
How much should the humidity in the basement be controlled so as not to be damp and moldy?
The most suitable humidity for human beings is 45%~65%.
When the room temperature is 8- 18℃, the human body will radiate heat to the outside, and the indoor relative humidity is between 40% and 60%, so you will feel comfortable and healthy.
In the comfortable indoor temperature range, the influence of humidity on human body is not obvious.
But when the temperature is 28℃ and the relative humidity reaches 90%, you will feel the temperature reaches 34℃.
70% of the humidity in the basement comes from the water molecules in the underground soil layer infiltrating into the basement through the capillary holes of the building concrete structure.
What is the humidity of the wall to be qualified? 2 What is the normal range of wall humidity?
The suitable temperature for mold growth is 28 degrees and the humidity is about 90%. Therefore, the humidity of the wall should not exceed 50%, otherwise it is easy to cause the putty of the wall to be moldy, leading to foaming at the base of the wall. Not only does it affect the appearance, but it also affects human health. You can find a moistureproof company to deal with it.
What are the methods to prevent the wall from getting wet?
1, close the window in the morning and evening to reduce moisture.
In daily life, humid weather has a great influence on the wall, especially when you return to Nantian, you must close the doors and windows of your home to prevent humid air from entering the room. When the temperature is high at noon, you can open the window for a short time.
2. Use desiccant and other products to absorb moisture.
Secondly, you can buy some items such as desiccant or moisture absorption box, or mix lime and washing powder with self-made temperature absorption box and put it everywhere in the room, which can play a certain dehumidification effect.
3. Use air conditioner and dehumidifier
In case of returning to Nantian, you can turn on the air conditioner at home for dehumidification, or buy a professional dehumidifier in the market. The dehumidification effect is good, but the cost is high.
4, timely inspection, remove the inner water vapor.
Finally, when you return to Nantian, you should always check the humidity of your home walls. Once you find water vapor on the wall, you should immediately take a dry rag or dehumidifier to absorb the water on the wall. Avoid moldy walls.
What is the humidity of the wall surface to be qualified? 1. What is the normal humidity of the room?
The indoor normal humidity is 40%-80% in summer and 30%-60% in winter. The suitable indoor humidity for the elderly and children is 45%-50%. If there are patients with respiratory diseases such as asthma, the indoor humidity is 40%-50%. If the humidity is too low or too high, the human body will feel uncomfortable, and it is less than 30%, which proves that the air is very dry. It is necessary to adjust the indoor humidity in time. If the humidity is too high, the wall will be dewed, so it should be dehumidified in time.
Second, how to adjust the indoor humidity
1, when the indoor humidity is too low, it is recommended to use a humidifier, whose working principle is to convert water into steam, thus changing the indoor humidity. You can also add appropriate amount of essence to improve indoor air quality. There are many kinds of humidifiers on the market, and the choice should be based on the size of your own space. Please ask the sales staff for details.
2. Use air conditioning in summer and heating in winter, and the indoor humidity will become lower, and the human body will feel very dry. It is suggested to put two pots of water indoors before turning on these devices, which can increase the air humidity. Or hang a wet towel near the heating or air conditioning to let the water evaporate into the air and increase the humidity of the air.
3. Ventilation is a simple and convenient way to adjust the humidity, because the outdoor humidity will be higher than the indoor humidity, and opening the window can lead the outdoor humidity to the room. But don't open the window in rainy days, so as to avoid the rain splashing in and damaging the furniture.
4. When the southern region returns to the southern sky, the indoor humidity becomes very high, which leads to humidity everywhere, which affects life and easily leads to moldy walls. If you want to reduce the indoor humidity, you can put lime and activated carbon in every corner of the room, or directly turn on the dehumidification function of the air conditioner for dehumidification.
