Asbestos is obviously a primary carcinogen. Why is there a lot of asbestos in the rice cooker?

Asbestos is a first-class carcinogen, but the asbestos contained in rice cookers will not have any influence on human body. Asbestos in rice cookers are generally around the pot ring or at the bottom of the rice cooker, which mainly plays the role of heat preservation. All the places where asbestos is put are sealed, and asbestos won't leak out at all unless the rice cooker is broken. In order to save money, some people break the rice cooker into pieces for maintenance. It is easy to cause asbestos fiber leakage after disassembly, which will cause harm to human body. I suggest you use the rice cooker normally, which is good for you.

In our daily life, it is not only rice cookers that contain asbestos, such as some asbestos cement boards, gypsum coatings on roofs and inferior carpets. These things all contain some asbestos, because the fibers of asbestos are so small that we can't see them with the naked eye. Therefore, when we come into contact with things with a lot of dust, we must wear masks, which can prevent a lot of harmful dust from being inhaled into the human body.

There are also many places in industry where asbestos materials are used. For example, in winter in the north, when the temperature is too low, people will use central heating, and the heating pipes exposed on the ground will be wrapped in a circle of asbestos materials. Some steel mills also wrap steel-making boilers with asbestos when making steel. Why do these factories like to use asbestos materials? This is mainly because asbestos itself is very resistant to high temperature, has a certain thermal insulation effect, and is cheap.

Some construction workers also use asbestos when they get some building materials. Generally, when building walls, construction workers will add some asbestos cement made of asbestos to the cement. Then why did they add asbestos cement? In fact, asbestos cement is added because it has good sound insulation effect, and when the weather is hot, asbestos, as a high-temperature resistant material, can also play a role in heat insulation. Although asbestos is a first-class carcinogen, it also plays a great role in daily life.
