In recent years, reserve charcoal has become synonymous with white charcoal, and some places outside Japan, such as China, use other kinds of charcoal. However, after 2004, China stopped exporting charcoal products to Japan on the grounds of protecting forests, which greatly reduced Japan's reserve charcoal supply.
Characteristics of reserve charcoal:
1, Porosity: There are countless pores of 2 ~ 3 microns in carbon particles, one gram of carbon, and the pore area is about 300 square meters. All the holes can be in contact with air, which can remove bleach or chlorine from tap water and make the water sweet and delicious. Chinese medicine also believes that charcoal can adsorb harmful ions.
2. Absorbing and releasing function: The carbon prepared at high temperature has almost no moisture and many small holes. Due to this characteristic, the prepared carbon has the functions of dehumidification and temperature regulation. When the ambient humidity is too high, it will absorb moisture, and when the ambient humidity is insufficient, it will automatically release moisture to keep the humidity in the air stable.
3. Far infrared ray release: When you hold charcoal in your hand, you will feel warm. This is because it can release far infrared rays. Because of this characteristic, it can be used to keep food fresh, help food to be heated evenly, and fully retain the original flavor of ingredients. Make bedding and put it beside you, which can make your body feel warm and help you sleep.
4. Supply negative ions: Nature's air is fresh in relaxation and freedom because it is rich in negative ions. Spare charcoal is the most natural air cleaner, which can produce negative ions, relieve stress and eliminate tension.
5, shielding electromagnetic waves: the occurrence of cancer is more or less related to electromagnetic waves. After high temperature firing, carbon is a good conductor, which has the same or higher shielding performance as metal plate and is the best electromagnetic wave shielding material.
6. Air purification of environmental water quality: placing charcoal in bamboo baskets or other containers can improve the living environment, purify and adjust indoor air humidity, protect buildings from termites and keep materials fresh.
7. Cooking delicious white rice: Wash charcoal in clear water with a brush and cook it with rice in an electric cooker, which can reduce pesticide residues on rice and make it full and delicious. In addition, putting spare charcoal into the rice jar can also prevent Mi Chong and keep it dry.
