Powder activated carbon
Activated Carbon Safety Data Sheet
Powder activated carbon is made of high-quality wood chips, coconut husk and coal as raw materials and refined through a series of production processes.
Production Process
- Physical method: wood chips → steam activation → refining → crushing
- Chemical method: wood chips screening → addition of zinc chloride or phosphoric acid → carbonization → activation → drying → grinding → packaging and storage
Advantages
Powdered activated carbon has the advantages of fast filtration speed, good adsorption performance, strong decolorization and deodorization ability, economy and durability.
Application
- 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.
Precautions
- 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.
