What is bamboo charcoal for? How is bamboo charcoal made?

The main characteristics of "bamboo charcoal" are: adsorption performance index, electromagnetic shielding performance index, harmful gas catalytic decomposition performance index, humidity control performance index, and far-infrared performance index.

Bamboo charcoal is a kind of charcoal made from more than three-year-old alpine moso bamboo as raw material and fired at a high temperature of nearly 1,000 degrees. Bamboo charcoal has a porous structure, its molecules are fine and porous, and its quality is hard. It has a strong adsorption capacity, can purify the air, eliminate odors, absorb moisture and prevent mildew, and inhibit bacteria and insects.

Contact with the human body can remove moisture and absorb sweat, promote human blood circulation and metabolism, and relieve fatigue. After scientific refining and processing, it has been widely used in daily life.

It can be deodorized, hygroscopic, and can also be used in food processing.

a. Black charcoal facial cleanser.

Facial CleanserThe facial cleanser is blended with charcoal powder to effectively absorb excess oil from the pores, leaving the face feeling fresh throughout the day.

b. Black carbon**.

It is said that black charcoal is comparable to the seabed mud we are familiar with, it can adjust the moisture and oil composition of **, and it only needs to be applied for one minute each time, which is most suitable for women who are busy with work.

c. Black charcoal shampoo.

Black Charcoal Shampoo Activated Charcoal not only has a cleansing effect, but also moisturizes and cares for hair, which is especially effective for broken hair. But it's shaped like ice cream, tastes like ink and is pitch black, I wonder if you have the courage to use it?

There are two main methods of firing bamboo charcoal in China, dry distillation pyrolysis and direct firing of earthen kilns.

1) Dry distillation pyrolysis method: its equipment is mainly external heating vertical retort, this retort can be used to pre-dry to 20% 25% moisture content of bamboo when firing bamboo charcoal, but also can use undried bamboo, but it is better to use pre-dried bamboo. Because there is basically no oxidation problem of bamboo charcoal in the firing process, the yield of bamboo charcoal is high, generally about 25%, and the high can reach 35%, and the firing cycle is generally 48 72 hours.

However, the refining temperature is not high, which affects the density of bamboo charcoal. The volume of the retort is small, and the yield of bamboo charcoal is low. Some manufacturers in Zhejiang Province use this vertical retort to burn bamboo charcoal.

2) Clay kiln firing method: it is the use of fuel (wood) direct heating, that is, the heat generated by the fuel combustion at the kiln mouth rises to the top of the kiln, and then diffuses to the kiln, most of which the hot air flow flows in the upper layer, and a small part of the high ridge heat radiates to the surroundings, which is slowly dried from top to bottom and pre-carbonized; Burning part of the bamboo in the kiln makes the temperature in the kiln continue to rise, remove the volatile substances, and the flue gas in the kiln circulates and flows, and the heat and temperature at each point are basically uniform, and the carbonization and refining stages are completed to obtain dense bamboo charcoal. The clay kiln firing method usually has stages such as smoking pre-drying, drying, pre-carbonization, carbonization, calcination (refining), and natural cooling.

Each stage has different temperatures, the smoke pre-drying stage is 60 100, the drying stage is 100 150, the pre-carbonization stage is 150 270, the carbonization stage is 270 450, and the calcination stage is about 450 to 1000. From the point of view of the process of burning and carbonizing in the earthen kiln, the temperature and carbonization speed of each stage are "eye-to-nose and smell" by the operator, firstly, to observe the changes of the chimney and the smoke outlet of the kiln door; The second is determined by smelling smoke. The fresh bamboo used in the earthen kiln is generally placed outdoors for about a week, and it takes about 1 week to smoke and pre-dry it in the kiln, and it takes a week to cool naturally to the kiln temperature of 50 60, and it generally takes 2 days to leave the kiln.

Therefore, it generally takes 25 to 30 days from kiln loading to charcoal, and the yield of bamboo charcoal is generally about 20%. The process is reasonable, and the yield of oxidative combustion in the later stage is less than 20%, otherwise it will be less than 20%, or even lower (due to air leakage or excessive air ingress). The cost of the earthen kiln is cheap and rented, the refining temperature is high, and the density of bamboo charcoal is large, but the quality stability is poor and the yield is not high.

Bamboo charcoal is made of moso bamboo, which has grown in the deep mountains for many years, and is fired at a high temperature of nearly 1,000 degrees for 30 days, and is carbonized by dry distillation in an oxygen-free state.

The role of bamboo charcoal

Bamboo charcoal is an internationally recognized drug addict, bamboo charcoal masks, gas masks are used bamboo charcoal.

2.Sprays and other drugs are easy to cause secondary pollution, and may damage furniture, while bamboo charcoal is physical adsorption, very safe, harmless to the human body, mildew and antiseptic effect on the home.

3.The high-tech product Tichang is removed at one time, and the release of poison gas at home is a slow process, so it was removed today, and it will smell again in a few days, and it is not low. And bamboo charcoal adsorption is a slow process, which is just the right match.

4.Breathable packaging, easy to use, bamboo charcoal** is low, and can be used repeatedly when dried in the sun.

5.Multi-faceted uses: fish tank water purification, preservation of ancient books and paintings, most afraid of mildew insect bites, refrigerators, toilets, cars can achieve disinfection and deodorization purposes.

Baking at high temperatures is to remove its moisture.
