Yuxin shell activated carbon is a high-almond shells and walnut shells as raw material, after drying, charring and high temperature steam activation refined processing of high adsorption performance of activated carbon. Appearance of black amorphous particles having developed pore structure, specific surface area Big, strong adsorption capacity, high mechanical strength, bed resistance, good chemical stability, easy regeneration, durability and other advantages, and having a particle size of various specifications.
For the six ring carbon irregular arrangement, resulting in a microporous activated carbon volume and high surface area. Shell activated carbon manufacturing process is basically divided into two, the first process including dehydration and carbonization, the raw material is heated at 170-600 dried at a temperature of ℃, and about 80% of the original organic matter charring. The second process is to make the charcoal-activated, it is through the use of activators such as water vapor and carbon reaction to complete, in the endothermic reaction is mainly produced by the CO and H2 mixed gas composition for burning charcoals heated to the appropriate temperature (800 至 1000 ℃), to burn them all biodegradable material, the resulting well-developed porous structure and huge specific surface area, which has a strong adsorption capacity.
Shell activated carbon activated carbon made from different materials having different pore sizes by coconut shell activated carbon system with the smallest pore radius. Wood activated carbon generally has the largest pore radius, they used to adsorb larger molecules, and almost exclusively in the liquid phase. The first type of granular activated carbon for water treatment in the city that is used in the field is made of wood, called charcoal. between coal activated carbon pore size between.
We are specialized in producing high-quality manufacturers of activated carbon, the Provincial Science and Technology Committee of high-tech enterprises, consumers trust the brand.
