What are the indicators of coconut shell activated carbon

Coconut shell activated carbon is used in filter rods. The main considerations are its adaptability during processing, quality stability, and the smoking quality of cigarettes. All factors are combined. Based on the current domestic detection capabilities of activated carbon, The performance indicators of activated carbon for cigarettes selected in the standard are:

Physical performance indicators: strength, specific surface area, particle size distribution, apparent density.
Chemical indicators: ash, moisture, PH value, heavy metals

Adsorption performance index: The adsorption of cigarette smoke by coconut shell activated carbon is mainly gas phase adsorption. powder activated carbon manufacturer According to our experimental verification results, the specific surface area has a good positive correlation with chemical adsorption indicators such as iodine adsorption, and the specific surface area reflects the overall adsorbability Therefore, the specific surface area is selected in the standard to characterize the adsorption capacity of activated carbon for cigarettes.

The production process of coconut shell activated carbon filter requires the suppression of dust generation, so we hope to set a relatively high strength index. The production practice of many activated carbon filter rod manufacturers shows that from the aspects of suppressing dust and protecting the cutting edge, the strength of coconut shell activated carbon for cigarettes must be greater than 90% to facilitate processing and utilization.

The special requirements of coconut shell activated carbon for tobacco are mainly to prevent the coconut shell activated carbon from inhaling or polluting other smells that are inconsistent with the smoke, thereby affecting the smoking quality of cigarettes. here Therefore, whether it is the direct smell of the coconut shell activated carbon itself or the smoking There is an indirect peculiar smell when smoking, as long as it affects the smell of cigarette smoking, it should be judged as a substandard product.
