With the improvement of people's living conditions and the development of technology, most people will buy a microwave oven. However, improper use will damage the microwave oven and even lead to an explosion. Then, let's introduce what the microwave oven can't heat.

what can't be heated by the microwave oven

1. Metal utensils, microwave can't penetrate metal, so food can't be heated. Some metal plugs will contact with the inner wall of the microwave oven, resulting in ignition, and the life of the microwave oven will be shortened gradually.

2. Plastic containers. Many plastic containers are very poor in plasticity. When they are put in, they cannot keep their original shape under the influence of external forces. Even some plastic containers have poor heat resistance and burn directly in the furnace, releasing toxic gases, which makes it even more difficult to heat food properly.

3, lacquerware utensils, lacquerware surface is coated with various colors of paint, usually when the microwave oven is heated, the coated paint will slowly fall off and melt, and never produce some harmful substances, which not only pollutes the food but also damages the container, which is not worth the loss.

4. Disposable plastic containers, just like yogurt boxes, can't be put in the microwave oven. These boxes are disposable, and they can't stand the high temperature at all. They can't keep their original state in the microwave oven, and these melted toxic substances will penetrate into the food, and the food will become inedible.

5, paper products, wood products, because these things will damage the utensils when they are flammable at high temperature, and even damage the microwave oven. The inside of the sealed container will easily expand when it is exposed to high temperature. If it cannot be distributed, it will explode if the air inside the container becomes less when it exceeds a certain temperature.

xiaobian summary: while enjoying the convenience brought by science and technology, we should also have corresponding awe of science and technology. Remember that although microwave ovens make our life more convenient, unscientific use of microwave ovens will also bring great trouble. Everything has two sides. We should learn modestly, use carefully and study patiently, so as not to get lost in the ocean of information.
