How harmful is rock wool to the human body, and what is the harm of rock wool to the human body?

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.

Rock wool. It is an inorganic fiber, which is environmentally friendly, safe, green, and harmless to the body.

Rock wool originated in Hawaii when it was the island of Hawaii.

The first volcanic eruption.

Later, the inhabitants of the island found wisps of melted soft rocks on the ground, which was the first human understanding of rock wool fibers, and the production process of rock wool was actually a natural process that simulated the eruption of a volcano in Hawaii.

Rock wool products are made of high-quality basalt.

Dolomite is the main raw material, which is melted at a high temperature of more than 1450 degrees and adopts the international advanced four-shaft centrifuge.

High-speed centrifugal fiber, 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, plus three-dimensional cotton laying for solidification, cutting, forming different specifications and uses of rock wool products.

Development status of rock wool.

China's rock wool manufacturing industry started late, the Chinese people's awareness of rock wool is not high, until November 2010, after the fire in Shanghai, the excellent fire insulation of rock wool was recognized by the society and vigorously promoted, while the Ministry of Public Security.

Issued the notice of Gong Xiao Zi [2011] No. 65 on the "Relevant Requirements for Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings".

The notice stipulates that the fire rating of building insulation materials must reach Class A, as the fire rating of rock wool to reach Class A1 is in short supply in the market, and many large-scale projects in China have caused delays in the construction period due to the lack of corresponding rock wool, and at the same time, it has also pushed up the rock wool on the market. At that time, the huge profits and the vast market attracted a large number of investors.

Rock wool will mainly cause harm to workers who come into contact with rock wool and can easily lead to the occurrence of pneumoconiosis.

Rock wool is made of high-quality basalt, dolomite, etc. as the main materials, plus three-dimensional cotton laying for curing and cutting, forming rock wool products of different specifications and uses. Because workers who are exposed to rock wool are prone to long-term inhalation of dust, it may lead to the occurrence of pneumoconiosis. Patients with pneumoconiosis have inconspicuous symptoms in the early stage, often dry cough or thick sputum, and late cough is aggravated with more sputum, such as combined with tuberculosis or bronchiectasis, and hemoptysis can be repeated.

In the late stage, the disease is severe, with cyanosis, clubbing, emphysema, and cor pulmonale. Therefore, if the above conditions occur in workers who are exposed to rock wool, they should be vigilant, go to the hospital for treatment in time, and ** as soon as possible.

Rock wool is not harmful to the body, but there is a small particulate matter in it that can affect breathing. Rock wool is an inorganic fiber, with environmental protection, safety, green, but we construction personnel still have to pay attention to the construction of rock wool has fine fibers, we inhale a small amount will not cause harm to the human body, if a large amount of construction inhalation will have an adverse effect on the lungs, you can usually wear a mask when working, the mask can play a good protective role, in addition to work to eat some food that helps to improve immunity, to avoid work caused by the loss of the body and other problems, You should also pay attention to other physical problems at work.

Only materials with high biological durability are retained in the category 2b classified by the International Agency for Research on Cancer, i.e. substances that may cause carcinogenesis in humans. These include durable ceramic fibers, which are used in industry to keep warm at high temperatures, such as cupolas, and some glass wool that is not used as thermal insulation. On the contrary, the most widely used glass fiber wool includes insulated glass wool, rock wool and slag wool are now considered non-carcinogenic substances to humans and belong to category 3.

Continuous glass fibers, which are mainly used to reinforce plastics, are also considered to be non-carcinogenic to humans.

The main hazards of rock wool fiber to the human body are ** damage, eye conjunctival damage and respiratory system damage. Dermatitis, conjunctivitis, and pneumoconiosis are more likely to occur. It is recommended that family members pay attention to wearing dust masks at work, preferably gloves to facilitate work, and wear goggles to minimize harm and damage to the body.

The main hazards of rock wool to the human body are ** injury, eye conjunctival injury, respiratory system injury, etc. Dermatitis, conjunctivitis, and pneumoconiosis are relatively more likely to occur. It is recommended that your family members pay attention to wearing dust masks when working, preferably wearing gloves to facilitate work, wearing goggles, etc., to minimize injury and damage to the body.

Rock wool has fine fibers, and long-term inhalation of rock wool fibers or dust can lead to endobronchitis, emphysema, laryngeal cancer, and lung cancer.
