Chemical method: wood chips screening → addition of zinc chloride or phosphoric acid → carbonization → activation → drying → grinding → packaging and storage
Powdered activated carbon has the advantages of fast filtration speed, good adsorption performance, strong decolorization and deodorization ability, economy and durability.
Chemical powder activated carbon: suitable for decolorization of sugars such as glucose, sucrose, and maltose.
For the removal of citric acid, bladder acid, oils and fats, chemical products, purification of nuclear molecules.
Physical method powder activated carbon: suitable for the decolorization, impurity removal and exquisite of medicine, food additive, monosodium glutamate, chemical industry, beverage, etc.
It is favored for waterworks and sewage treatment plants.
It has a wide range of applications in food, medicine, decolorization, crystallization, filtration, and material purification.
It is also the main material of activated carbon filter felt and activated carbon foam.
Activated carbon is a porous adsorbent. Therefore, water immersion must be absolutely prevented during transportation, storage and use. After water immersion, a large amount of water fills the active voids, making it ineffective.
During the use of activated carbon, tar-like substances should be prohibited from being brought into the activated carbon bed, so as not to block the gap of activated carbon and lose its adsorption effect.
When storing or transporting activated carbon, prevent direct contact with the fire source to prevent fire.
