What are the potential hazards of asbestos to ordinary people?

Introduction: Asbestos is a kind of food that is easy to come into contact with in daily life, and in chemical experiments, asbestos is usually used as a backing board when heating alcohol lamps, and asbestos is relatively easy to contact. So where is the potential harm of asbestos to ordinary people?

In fact, asbestos is in the process of production and manufacturing, if it is a complete individual, there is no harm to ordinary people. Moreover, asbestos is a fibrous object, so it is often used in daily life. However, it is worth noting that if the asbestos is broken and damaged, and there is a risk of carcinogenesis after inhalation, it is said that asbestos has a potential carcinogenic risk.

This is also the reason why many substances that are in close contact with the human body cannot be used. If there is indeed damage during use, then there will be carcinogenesis. If you move into a new home or rent a house, you must check the bed or the surrounding material, if there is asbestos material, you should immediately complain, because it does not comply with the relevant regulations.

Moreover, when buying things, you should also pay attention to whether asbestos is present, so that you can avoid the potential risk of asbestos being carcinogenic.

In the process of decoration, you must pay attention to if you do not ventilate and clean in time, then it will lead to your own body injury. In the process of choosing furniture when decorating, we must choose a big brand guarantee, so as to avoid the impact of these materials on human health. After the decoration is completed, you can put some green plants in the home, and properly ventilate, in this case, you can keep the home environment clean and tidy.

You can buy some activated carbon, activated carbon is adsorbed, so that the family environment can be purified faster, don't be very anxious to move in and out after the decoration.

This substance can be inhaled in the lungs and body, and then it can cause serious lung diseases, respiratory infections, coughing, sneezing, and runny nose.

It is reflected in the lungs, because asbestos cannot be digested and absorbed by the human body, it will remain in the lungs, stomach, throat, digestive tract, and will also cause bronchitis.

In terms of carcinogenicity, if the human body inhales this kind of thing, it is very dangerous, it will cause infection, and it will also cause life-threatening.

Once this substance is inhaled into the human body, it will cause cancer, so it is particularly dangerous and we must stay away.

There is a big difference between rock wool and asbestos, and they are both the main insulation materials.

1. Asbestos: It is a natural mineral fiber, and the fiber is not biosoluble, if inhaled for a long time, its accumulated toxicity will cause irreversible damage, such as pneumoconiosis and lung cancer. Inhalation of asbestos fibers can cause various lung diseases, including cancer, and it is now banned as a building material in many countries.

On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) classified all forms of asbestos on the list of Group 1 carcinogens.

Rock wool: It is made of natural rock melting, which is non-toxic and harmless to the human body, not easy to breed bacteria and insects, does not pollute the environment, and has done carcinogenic tests, and it is concluded that rock wool products belong to the third category of materials (group3): it will not have carcinogenic effects on the human body.

2. Asbestos: Asbestos fibers can be woven into yarn, thread, rope, cloth, packing, etc., as materials or linings for transmission, heat preservation, heat insulation, insulation and other components.

Rock wool: Rock wool can be made according to different uses: felt, strips, tubes, granules, plates, etc., which are applied to:

Nuclear power plants, power plants, chemical plants, large kiln insulation, building exterior wall insulation, roof and curtain wall insulation, isolation belts, cabins, shipboard sanitary units, crew lounges, power compartments, etc.

What is the difference between rock wool and asbestos? Let's talk about asbestos first, asbestos is the abbreviation of asbestos fiber, which is made of silicate minerals as raw materials, and the longer asbestos fibers can be used to manufacture fireproof textiles, such as asbestos belts, asbestos cloths, etc.; The short fiber can be used to make asbestos cement products, asbestos sound insulation materials, asbestos insulation materials and other materials. However, asbestos fiber, after research and testing, appeared on the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer on October 27, 2017, which can cause diseases such as asbestosis and pleural mesothelioma, and many countries have chosen to completely ban the use of this dangerous substance.

What kind of material is rock wool? It is a thermal insulation and soundproof material made of basalt and other minerals, which is often used for the insulation of building exterior walls and the fireproof sealing materials of building curtain walls. Stone wool is a commonly used material in areas with large temperature differences, such as the north.

If your house has been renovated with exterior wall insulation, it is likely that rock wool insulation materials are used. Rock wool is different from asbestos, with stable chemical properties, environmental protection, and harmless to the human body. Environmentally harmful substances such as CFCS, HCFCS and HFCs are not used in the production process, which will not harm human health and will not increase the risk of cancer.

Above, it can be known that rock wool is not asbestos, although these two materials are fiber insulation materials, can be used for sound insulation and noise reduction and other purposes, but rock wool is not a carcinogen, but in the construction of building insulation projects, it is still necessary to pay attention to protection, to avoid inhaling too much shedding "fiber".

The difference is huge, two different things. Rock wool is a product of stone expansion. Asbestos is a type of fiber.

Asbestos is a general term for several different fibrous minerals that have good thermal insulation, insulation, and wear resistance, and are used in the manufacture of building materials, textiles, thermal insulation products, and insulation products, among others. Asbestos tiles, asbestos cement boards, asbestos insulating gloves, etc. are all common asbestos products in daily life.

Exposure to asbestos can be significantly increased by mining core asbestos, manufacturing asbestos products, constructing or demolishing buildings that use asbestos building materials, living or working in buildings where asbestos building materials are not properly disposed of, repairing brake pads in automobiles, manufacturing and repairing ships, and wearing asbestos clothing. The World Health Organization estimates that about 100 million people worldwide are exposed to asbestos in the workplace, and at least 90,000 people die each year from asbestos-related diseases.

Classified as a "human carcinogen" by the International Organisation for Research on Cancer (IARC), asbestos is one of the most important occupational carcinogens, accounting for about half of all deaths caused by occupational cancer. Asbestos can cause cancerous changes in the lungs, lung membranes, stomach, esophagus, colon, rectum, vocal cords, and kidneys, and 70% to 80% of cases of mesothelioma (a type of cancer that occurs in the lining of the chest or abdominal cavity) are associated with asbestos, and long-term inhalation of large amounts of asbestos fibers can also lead to asbestosis. These diseases do not show symptoms immediately, but appear many years after the patient has been exposed to asbestos.

Different types of asbestos have different health effects, and the threshold for carcinogenic risk of chrysotile asbestos has not been determined. The World Health Organization has recommended that the use of all types of asbestos be stopped, and some countries have completely banned asbestos, but chrysotile asbestos is still widely used in developing countries.

Asbestos itself is non-toxic, but because some of the asbestos 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 cancerous organs. There are still hidden dangers when covered with putty powder, and the fine asbestos fibers may float out through the gaps, and if the putty powder falls off, the harm is even greater. The old asbestos board can be crushed and buried deep or disposed of as industrial waste, or it is called **station**, but it should not be dumped into rivers, lakes and seas.

Workers exposed to rock wool can have chest x-ray changes: i.e., pneumoconiosis changes. In addition, the chest x-ray of contact workers such as bleached soil fiber, green slope stone, and sepiolite showed atypical shadows, and lung biopsy showed changes such as bronchiolitis, reticular fibroplasia, and fibrous foci.

Differences: 1. Different properties: asbestos is a silicate mineral product with high tensile strength, high flexibility, chemical and thermal erosion resistance, electrical insulation and spinnability.

Rock wool is the result of the first volcanic eruption on the island of Hawaii, when the island's residents found wisps of melted soft rock on the ground.

2. Different characteristics: asbestos is composed of fiber bundles, and fiber bundles are composed of very long and thin fibers that can be separated from each other. Rock wool products are made of high-quality basalt, dolomite and other main raw materials, after melting at a high temperature of more than 1450, the use of international advanced four-axis centrifuge high-speed centrifugation into fibers, at the same time spray a certain amount of binder, dust-proof oil, water-repellent agent after the collection of cotton collector, through the pendulum process.

3. Different uses: rock wool can be made according to different purposes: felt, strips, tubes, granules, plates, etc.

Bluestone and amosite account for less than 5% of total asbestos consumption and are mainly used in shipbuilding. Anthophyllite asbestos is a type of asbestos similar to talc, which is often used as industrial talc.

Asbestos is a kind of silicic acid pat slow salt mineral fiber that is widely used in building materials fireproof board, and it is also the only natural mineral fiber, which has good tensile strength and good thermal insulation and corrosion resistance, and is not easy to burn, so it is widely used in concealment.

There are many types of asbestos, with chrysotile asbestos content is the most abundant, the most widely used, 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 inhaled into the human body, they will be attached and deposited in the lungs, causing lung diseases, such as: asbestosis, pleural and peritoneal intercutaneous tumors. These lung diseases tend to have a long incubation period (15-20 years for lung cancer and 20-40 years for mesothelioma), and in severe cases, lung cancer can occur.

Asbestos has been confirmed by the International Agency for Research on Cancer as carcinogenic.
