Product Details
Powdered activated carbon description
Powder activated carbon is produced by coals, nuts shells or wood chips, with a developed middle-pore structure, high adsorption capacity, and good filtration.
Powdered activated carbon classification based on materials
Powder activated carbon is mainly divided into coal quality activated carbon with wood powdery activated carbon.
Coal powdered activated carbon
Coal based activated carbon powder is used coal as raw materials. It has high chemical composition. There are many impurities in coals, threfore, based on most countries national food standards, they cannot be used in medicine, food or industry. and coal gas-powered activated carbon is only applicable to chemical industry, sewage treatment, living water and other industries.
Wooden powdered activated carbon
Wooden powdered activated carbon is made of excellent husks, wood chips, and the appearance is black fine powder, non-toxic, tasteless, has a large specific surface area, strong adsorption capacity, suitable for sugar, pharmaceutical, beverage, alcohol, etc. The water-quality water purification industry is also widely used in the decolourization, refining, purification and sewage treatment of organic matter solvents.
Powdered activated carbon classification based on making process
Powdered activated carbon is made of fine wood chips or smokeless coal, and there are two physical laws and chemical methods. After activation of water vapor, refined treatment, pulverized.
About the powdery activated carbon process process is as follows:
- Wood chips, smokeless coal screening and drying.
- Ingredients and impregnation.
- The dish and inactivation.
- Recycle, rinse.
- Centrifugation dehydration, drying and grinding.
- Enter the packaging process, warehouse storage.
Physical processing: Steaming powdered activated carbon
Properties: After the excellent husk and wood chips are raw materials, after steam activation, refining treatment, pulverization, the appearance is a black fine powder, non-toxic, tasteless, has a large surface area, strong adsorption.
Uses: This product is applicable to medical, food additives, monosodium glutamate, chemical, beverages and other products, etc.

Phosphoric acid method processing
Powered activated carbon produced by phosphoric acid, has a developed middle-pore structure and developed specific surface area, large adsorption capacity, fast filtration, and does not contain zinc salt. It is widely used in food industry sugar, glutamate, lactic acid and salt, citric acid and salt, wine, seasoning, animal and plant protein, biochemical products, pharmaceutical intermediates, vitamins, antibiotics and other products. Deodor, deodorant.
Applications
Powdered activated carbon application field
