The main reason lies in the fact that asbestos is cheap, there is no other material that can replace asbestos, and it cannot be given up in the short term.
One, I have begun to ban asbestos
While the carcinogenicity of asbestos is very strong, but the use of asbestos is too wide, asbestos can be used not only in the construction of houses. It was also used in all kinds of industries. In 2003, China began to ban the use of asbestos materials to make motor vehicle brakes, and in 2005 banned the import and export of hornblende minerals, and later banned the use of asbestos materials in construction. Even after banning the use of asbestos in so many fields, asbestos is still used in China because there is no way to completely ban asbestos, which is so widely used that it will take some time to abolish it completely.
Two, the cost-effectiveness of asbestos is too high
But for other materials, asbestos is too cost-effective, the price is relatively cheaper, the cost of acquiring it is also cheaper, the only problem is its carcinogenicity. To combat the carcinogenicity of asbestos, workers who work with asbestos are fully equipped, but do not wear masks. Even then, the workers are still at risk of developing an illness, and if the workers do develop an illness, then it is difficult for their family members to escape. Even so, it is quite difficult to come up with a real name for industry completely, especially for a developing country like ours, where industrial development would require greater economic costs if asbestos is excluded.
Third, the manufacture of substitutes
Currently our country in order to deal with the problem of carcinogenicity of asbestos, has begun to manufacture some alternative skin, for example, we use the temperature 10 years will be much better than the banned erosion of cotton, as for the bedroom after some special treatment of carcinogenicity of the bedroom inside the weaker. And asbestos is something that requires long-term exposure to cause cancer, so our country is also trying to find ways to slowly make some stone door substitutes to completely replace asbestos, and to provide better protection for workers.
