There was once a material that swept the world and was even applied to all aspects of life, it had good heat insulation, anti-corrosion, insulation, heat preservation, and it could not be ignited. But with so many advantages, the use of materials is banned in more than 60 countries around the world, so why is it banned?
Asbestos is a very common ore, and if you tear it by hand, you can remove strips of flocculents, which can be used to weave cloth, such as the fire-plagued weaving cloth during the Spring and Autumn Period and the Warring States Period. According to historical records, fire weaving refers to the cloth skin spun with asbestos fibers, and the woven cloth skin will be put into the fire to clean, which can remove the dirt on it, so it is called fire weaving. In modern times, human beings have mixed asbestos fibers with cement to develop a lightweight, waterproof, fireproof, thermal insulation, and most importantly, very cheap building materials, and appeared in all corners of life in a very short period of time.
China used to be the world's largest demand for asbestos and the second largest producer of asbestos. So why is such excellent asbestos banned?
After the end of World War II, a small town producing asbestos ore in Australia began to mine asbestos ore in large quantities in order to make a living, and the ore was processed and sold to various places. Some of the dust from the asbestos fibers left over from the processing was emitted directly into the air, and they did not know at the time that the ore that would bring them great wealth could also take away their health. When these fine fibers enter the lungs, they will cause pulmonary fibrosis, that is, asbestosis and pneumoconiosis, and the fibrosis of the lungs will make the lung tissue lose its respiratory function, just like a balloon that has lost its elasticity, without the function of exhalation and inhalation.
On top of that, insomnia can also cause mesothelioma, a malignant cancer that exists in the lining of the chest and abdominal cavity. The most terrifying thing is probably asbestosis, the onset of the disease takes more than ten years, so even if someone dies of respiratory loss or lung cancer at that time, no one can realize that the culprit of all this is the ubiquitous asbestos.
Many people should have known about it. Especially asbestos tiles, in rural areas, basically every house has some roofs built with asbestos tiles, but after this kind of asbestos tiles have experienced long-term wind and sun exposure, asbestos fibers will be exposed from the broken place, once you come into contact with these fine fibers that are imperceptible to the naked eye, it may enter your lungs with breathing. Therefore, if you still have asbestos products at home, you must not remove or clean them up yourself.
-
The fibers inside asbestos, if inhaled by the human body for a long time, will not only cause pulmonary fibrosis, but also induce bronchial diseases, which is not good for people's health.
-
Asbestos is a natural ore, the main reason is that the substance itself is harmless, but the harm mainly comes from a fiber inside, and this fiber is difficult to find with the eye, if you inhale these fibrous substances for a long time, it will not only lead to pulmonary fibrosis but also induce bronchial disease, which has a very serious impact on the body.

Asbestos is actually a mineral, neither stone nor cotton. Asbestos is easy to enter the lungs, it is difficult to be digested or excreted by the human body, which will lead to respiratory diseases, and long-term exposure to asbestos is easy to get occupational diseases, which will pollute the environment, so it will be banned by many countries.
-
Asbestos itself is non-toxic, highly fire-resistant, electrically insulating and insulating, making it an important fireproof, insulating and thermal insulation material.
It is non-toxic, but because some of the Shichai potato cotton particles are extremely fine, they are scattered in the air in the form of dust and are easily deposited in the lungs after being inhaled, resulting in organ cancer.

1. Due to special reasons in China's history, asbestos is used in large quantities, the number of production enterprises is huge, and it is unlikely to be banned at once.
2. China is a low-cost country, and the labor protection in this area has not yet been perfected. Moreover, asbestosis, as well as lung cancer and pulmonary fibrosis caused by asbestos, are mostly affected by migrant workers, and there is no power representative to speak for them. In fact, it is the lack of occupational health and safety management.
3. Asbestos is cheap, saves money, and there are too many industrial raw materials used in production. A total ban will have a significant impact on all walks of life.
Asbestos is currently partially restricted and banned in China. With the standardization of asbestos products in various countries, China should also more strictly regulate asbestos products, conduct targeted investigations on prohibited and restricted substances in products, and carry out corresponding testing and certification as required, so as to avoid disputes and economic losses after export because they do not meet the relevant regulations.

At that time, a small town in Western Australia called Witnum was rich in crocidolite. Due to the development of the mining industry, the number of workers required has also increased, but these workers have experienced widespread deaths, and after research, experts have found that asbestos is highly carcinogenic.
In fact, asbestos itself is non-toxic, and the static state will not cause harm to the human body, but in the process of mining and use, the fragile asbestos fibers are inevitably destroyed, although these fibers are fragile, but they are as strong as steel, these broken fibers are very light, like dust can float in the air or water for weeks.
If they are inhaled into the lungs, asbestos fibers will stick like nails into the lungs, causing fibrosis in the lungs as they precipitate over time, forming "asbestosis". In addition, it may also cause diseases such as pleural mesothelioma, lung cancer, and gastrointestinal cancer. And because the diseases caused by asbestos tend to have a long incubation period, which may not cause the disease until 10 to 40 years later, asbestos is currently also classified as a group 1 carcinogen.

Its harm to the body is easy to lead to malignant pleural mesothelioma, easy to lead to lung cancer, easy to lead to asbestosis, lead to decreased immunity, and lead to aspiration pneumonia.

Summary. Asbestos, also known as "asbestos", refers to silicate mineral products with high tensile strength, high flexibility, chemical and thermal attack resistance, electrical insulation and spinnability, and is a general term for natural fibrous silicate minerals.
It is an important fireproof, insulating and thermal insulation material, and because asbestos can cause diseases such as asbestosis and pleural mesothelioma, the World Health Organization has included it in the list of a class of carcinogens.

Of course not.
It's just a normal rope.
Is it harmful for my family to use asbestos tiles to cover it for a long time.
Rest assured, asbestos tiles are not harmful to the human body, which have been tested by experts.
So there is no concern about that.
Thank you doctor. You're welcome, I'm honored to answer for you, please give a thumbs up.

1. The carcinogenic effect of asbestos requires the inhalation of asbestos fibers into the lungs, and irreversible lung damage will be caused through long-term accumulation.
2. But the asbestos net is already a finished product and is extremely dense. Even if the edges are fluffy, the short-term pollution to the environment is extremely limited.
The main reason why young people are getting poorer is because of advanced consumption. Now as long as people have a mobile phone, many problems are solved, which is particularly convenient. Sometimes you don't have money in your mobile phone and you can use Huabei, credit cards, etc. to spend. >>>More
The formation of stones is due to the formation of rocks on the earth through complex geological processes through long-term weathering, erosion, sedimentation and metamorphism. These actions include temperature changes, pressure changes, chemical reactions, etc., which lead to physical and chemical changes in the rocks, eventually forming different stone types. >>>More
I think this is a very good, very positive state, the sea of learning is endless, the most afraid of self-satisfaction, 'feeling ignorance' is a kind of self-reflection and scrutiny, people only feel ignorance, will continue to learn, think, explore, create, it is precisely because of those who feel ignorant that human science and technology are constantly innovating, scientists do not know what is outside the earth, feel very ignorant, so to explore, discovered nine galaxies, human beings landed on the moon, Medical scientists don't know what new viruses will be in the future, they feel very ignorant, so they go to create, and now our medical equipment is getting more and more advanced, and most people feel that they know everything, so they live an ordinary life in a mess.
Because there was no unified system in ancient times, the social system was quite chaotic. So in order to punish those who do many evils, torture was invented.
The cow's eyes also have a tear stain in normal times, which is the way of steak salt, and when the cow is slaughtered and struggling, it will squeeze the tear sac, so that tears will flow.
