Powder activated carbon is a very popular type of activated carbon. So, will the packaging of powdered activated carbon affect the quality of the product? Next, let me introduce it to you!
Due to the influence of production environment, packaging, transportation, and storage conditions, powdered activated carbon can adsorb water and air, causing its adsorption capacity to decrease. If it is not activated before use, it will affect the ability of powdered activated carbon to adsorb heat sources and impurities, and affect the quality of the formulation. Therefore, pre-treatment should be carried out according to the detailed situation before use, which can greatly improve the heat source removal ability of activated carbon. Experiments have shown that the heat source removal effect of activated powder activated carbon is significantly better than that of untreated activated carbon.
The commonly used pre-treatment methods for powdered activated carbon include:
Due to poor packaging sealing, absorbing moisture and air will cause activated carbon to adsorb before it can land. It can be baked at 120 ℃. Perhaps after boiling treatment.
For those that are slightly alkaline or unstable to iron salts, acid or alkali treatment should be used when using powdered activated carbon. Detailed method: Take 1 part of powdered activated carbon, add 4 parts of 5% sodium hydroxide, boil for 30 minutes, filter dry, wash with injection water until neutral, then sequentially boil with 4 parts of 5% hydrochloric acid and 4 parts of injection water for 30 minutes, filter dry, and repeatedly rinse with injection water until there are no chloride ions, then dry.
