Asbestos is highly fire-resistant, electrically insulating, and insulating, and is an important fireproof, insulating, and thermal insulation material.
Asbestos, also known as "asbestos", is a commercial term that refers to silicic acid with high tensile strength, high flexibility, resistance to chemical and thermal attack, electrical insulation, and spinnability.
Salt mineral products. It is a general term for naturally fibrous silicate minerals.
There are 2 types of minerals in total, 6 minerals (serpentine.
Asbestos, amphibole asbestos, actinolite.
Asbestos, anthophyllite asbestos, amosite, tremolite.
asbestos, etc.). Asbestos is made up of bundles of fibers, which in turn are made up of very long and thin fibers that can be separated from each other. However, asbestos fibers can cause asbestosis and pleural mesothelioma.
and other diseases, many countries have chosen to completely ban the use of this dangerous substance.
27 October 2017, World Health Organization.
The list of carcinogens published by the International Agency for Research on Cancer (IARC) is preliminarily collated and referenced, and asbestos (various forms, including actinolite, amosbestos, anthophyllite, chrysotile asbestos, crocidolite, tremolite) is in the list of a class of carcinogens.

Asbestos fiber has the characteristics of acid resistance, alkali resistance, heat insulation, insulation, fire prevention, not afraid of heat, not afraid of burning, etc., and is widely used in industryIn general, when used in physical and chemical experiments, it is to make the beaker and other containers evenly heated, so please give it praise.

Asbestos is used on aircraft carriers.

Why is asbestos so harmful.

1. What is asbestos?
Asbestos is a generic name for natural fibrous siliceous minerals, is a silicate mineral fiber that is widely used in building materials fireproof board, and is also the only natural mineral fiber, it has good tensile strength and good thermal insulation and corrosion resistance, not easy to burn, so it is widely used. There are many types of asbestos, the three most common are chrysotile (white asbestos), amosite (brown asbestos) and crocidotile (blue asbestos), among which chrysotile is the most abundant and widely used.
2. The harm of asbestos to the human body:
Asbestos itself is not toxic, its biggest harm comes from its fibers, which is a very small, almost invisible fiber, when these small fibers are released, they can float in the air for a long time and be inhaled into the human body, and the inhaled asbestos fibers can accumulate in the human body for many years, attach and deposit in the lungs, causing lung diseases.
Exposure to asbestos fibres can cause the following diseases:
Lung cancer, mesothelial cancer, pleural or peritoneal cancer.
Asbestosis is a fibrosis of the lungs (asbestosis) caused by fibrosis of the tissues lining the lungs
Symptoms of asbestos-related diseases tend to have a long incubation period, which may not appear until about 10 to 40 years after exposure to asbestos (15 to 20 years for lung cancer and 20 to 40 years for mesothelioma).Asbestos has been identified as a carcinogen by the International Agency for Research on Cancer.
1) Most of the thermal insulation and sound insulation materials of the ceilings and pipes in some old houses are asbestos products, and when these asbestos materials are dismantled, cut and reshaped, a large number of fine asbestos fibers will be scattered in the air. Some building materials and home improvement materials such as asbestos cement and vinyl plastic flooring can emit fine asbestos fibers.

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.
