General charcoal and activated carbon what is the difference?
The production cost of different bamboo charcoal only once the carbonization process of activated carbon, and also need an activation process, its cost is much higher than that of bamboo charcoal, about 3 - 5 times. So the selling price of the product is bamboo charcoal 3-5 times.6, and not the same as raw material consumption of activated carbon as raw material consumption and high 3-5 times than the bamboo charcoal, such as 6T (tons) of bamboo can be fired 1t bamboo charcoal, but the 3-5t can process 1t bamboo charcoal activated carbon. Of course, the coconut shell activated carbon raw material costs will be higher, but the effect is better, not a.7 shape with a barrel charcoal, bamboo charcoal in different poses and with different expressions, pieces of pieces of carbon, carbon, carbon particles, carbon powder and so on and the use of a wide range, such as carbon tube can be made into all kinds of crafts, charcoal tablets can be used for water to cook, and so on; and the active carbon is generally only powder (diameter less than 0.18mm (8mm) and the particle diameter is less than or equal to two), because there is no large activated carbon, so its application is very The limitations of the.8, the adsorption of bamboo charcoal to the pores of the main hole, and activated carbon is very different
That is the sum of 1 grams of carbon surface area and pore area. All the bamboo charcoal firing temperature is over 500 DEG C, the specific surface area between 150 square meters to 350 square meters of /g /g; and by physical or chemical methods are made of activated carbon, the specific surface area can reach 900m2/g or even 2000m2/g. Because of the more developed pore structure and the larger specific surface area, the adsorption function is stronger, so the overall ratio of activated carbon adsorption of bamboo charcoal is more.4, hardness difference of bamboo charcoal density, high hardness, non friable, suitable for wearable textile products; and the active carbon hardness of different materials differently, coconut shell activated carbon high hardness with the production of activated carbon, bamboo has light weight, thin, fragile, so it is not suitable for high wear resistance products.
But to microporous activated carbon dominant pore diameter is divided into three categories: macroporous (more than 50nm), accounting for about 10 to 30% of the total pore volume, micropore (less than 2nm) accounted for about 60 to 90% of the total pore volume, pore and transition pore (2nm = phi = 50nm), ca. the total pore volume of 5 ~ 7%, the average pore diameter is about 1.5nm. molecular diameter of the harmful gas (formaldehyde, benzene, ammonia, 0.44nm 0.48nm 0.414nm, 0.58nm 0.60nm, toluene and xylene 0.324nm methane etc.) thus, bamboo charcoal for these harmful gases has no adsorption purification function, and it is the diameter of the activated carbon molecular fusion with these harmful gases, the adsorption of harmful gases and the confinement properties are better! 3, the specific surface area of different surface area refers to the unit mass occupied surface area size
The different processing technology of bamboo charcoal after carbonization, and activated carbon in addition to carbonization process, but also after the activation, pickling and drying stage.2, microstructure of different pore diameter: bamboo charcoal than activated carbon: small holes inside the bamboo charcoal tube, vascular bundle, thin tissue holes on the side wall of the pore by bamboo charcoal the big hole, the diameter of 200nm (nano unit, the same below) about.
