The warmth of modern homes is not unusual, especially in the cold winter months. It is really warm. As the floor heating is heating up from under the floor, in line with the physiological requirements of the body's feet and head cold, but it also has a fatal harm, what is it in the end? The following will follow Xiaobian together to understand it.
The hazards of warmth , long-term use of warmth will induce cancer growth. Because the ground heating itself has radiation, it will affect the body's immunity and body functions, which will cause many cells in the body and may lead to the occurrence of cancer. Through the results of the study, it has been learned that the growth rate of cancer cells is very fast for people who have been using warm soil for a long time.
2. The hazards of warmth 2. As ground heating is heated from the bottom up, dust on the ground will be raised and floated in the air, making it particularly prone to chronic pharyngitis, rhinitis, and bronchitis. Some warm winter pharyngitis is always treated poorly. This is the reason. In particular, families with chronic bronchitis and emphysema at home do not recommend installation.
The hazards of warmth 3, the frequent use of floor heating will affect the human reproductive system, especially for pregnant women is very unfavorable, serious will lead to miscarriage or fetal malformation, but also affect the male body's sperm. Therefore, it is recommended that everyone choose to use it carefully.
The hazards of warmth 4, warming will also make the risk of cardiovascular and cerebrovascular diseases increase. If the human foot and lower extremities are under high temperature for a long time, the downward resistance of the blood increases, leading to upward acceleration, increasing pressure on the heart, making it easy for people to get cerebrovascular diseases. Therefore, there are people with three heights and heart diseases at home. Do not install floor heating.
The dangers of warmth to the ground 5. It is said that the electromagnetic radiation that the ground warmth may also cause the development of children’s intelligence. Every year, a large number of children born in China have some deficiencies. Among them, the children's impact on children's warmth is also very important. It is also one of the most likely causes of leukemia.
The hazards of warmth 6, easy to cause leg varicose veins and phlebitis and other diseases. If the warmth causes the surface temperature to be too high for a long period of time, causing the feet and lower legs to be exposed to high temperatures for a long period of time, the blood vessels may expand, eventually causing varicose veins and phlebitis and other diseases. This is a story from a few decades ago. Some people got varicose veins. At the beginning, doctors couldn't find the cause. Only at the end of the day did the culprit find out that the warm surface temperature was too high.
Xiao Bian concludes: The above is an introduction to the six major hazards of warmth, hoping to help everyone to further understand the warmth. In fact, any electronic product will have certain radiation and harm, more or less, people will worry about it is normal. Therefore, Xiaobian thinks that it is better to use less or less for radiation products.
Taps and dies are tools used to create purpose screw threads, which is called threading. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called tapping, whereas the process using a die is called threading.
Using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies-called chasers-made for that purpose.
