I would like to ask what kind of asbestos damage to humans, and asbestos into the human lungs can not be recycled?
Asbestos itself is not toxic, it's the greatest harm from the fiber, which is a very small, almost invisible to the naked eye fiber, when these tiny fibers release, long time floating in the air, easily inhaled.Asbestos dust enters the body, gradually deposited in the lungs, resulting in fibrosis of the lungs, thickening of the pleura, called asbestos lung. Asbestos lung early symptoms are not obvious, after a period of time, slowly feel physical decline, after labor prone to breathing difficulties, chest pain, heart trouble, and often cough. The condition continues to increase, the weight obviously reduces, the whole body is weak, and has the bronchitis and the pleurisy. Patients with advanced asbestos can suffer from heart disease, severe heart failure, and eventually die. Of course, asbestos carcinogenesis is a very long incubation period, most of which are exposed to asbestos for 10~20 years before symptoms appear.
Data show that asbestos can cause primary lung cancer and mesothelioma, and 90% of patients with pleural mesothelioma are exposed to asbestos history. Asbestos processing workers around the world have a higher incidence of cancer than workers of ordinary trades, and the mortality rate is quite alarming. Therefore, asbestos production workers should pay special attention to the prevention and control of asbestos dust.
Here's an introduction: asbestos is a natural fibrous mineral whose crystalline composition contains silicate compounds such as iron, magnesium, aluminum, calcium, and nickel. Because asbestos has good acid, heat and insulation properties. Widely used in refractories, building materials, gaskets, filters, car brake pads and so on, and now there are more than 3200 varieties of asbestos products in china. There are 5 main categories: asbestos insulation products, asbestos sealing products, asbestos brake products, asbestos building products (asbestos cement products) and asbestos special products. The main products are asbestos, asbestos rope, electrolytic cloth, diaphragm cloth, asbestos packing, high and low pressure asbestos rubber sheet, asbestos cement tile and asbestos cement pipe, friction materials and so on. At present, our country asbestos cement products enterprises, mainly the production of asbestos cement corrugated sheet, followed by asbestos cement plate and asbestos calcium silicate board, and asbestos cement pressure pipe and cable pipe etc..
