Particle strength is also a main index of granular activated carbon.
In order to improve the particle strength of granular activated carbon, usually take some special processing measures, such as adding some material help plasticizing and proper mechanical treatment 4 or control in the process of kneading kneading temperature and kneading time, can greatly improve the strength of granular activated carbon particles, making the strength of the granular activated carbon has reached the fruit shell carbon intensity index.
However, there are also some disadvantages :(1) it is highly corrosive to equipment; (2) it pollutes the environment, etc., which makes the chemical method limited to a certain extent.
There are many researches on activation by adding H3P04 at home and abroad. In China, the development and research work of preparing activated carbon by using phosphoric acid method with wood chips as raw material has been carried out since the end of 1980s,It has been successfully put into industrial application in the 1990s,The mesopore (transition pore) structure of products produced by phosphoric acid activation method is well developed and has wide application fields.
The pressure from substitutes and a moderate level of threat from new entrants has resulted in the low bargaining power of suppliers.Price forecasts are beneficial in purchase planning activated charcoal powder wholesale, especially when supplemented by the constant monitoring of price influencing factors. During the forecast period, the market expects a change of 5.00%-8.00%.Identify favorable opportunities in Activated Carbon TCO (total cost of ownership).

Activated carbon is a strong adsorbent, the adsorption of gas and adsorption capacity are very large.
When the gas molecules occupy the adsorption surface of activated carbon, the adsorption of activated carbon will be reduced, resulting in the so-called "poisoning" of activated carbon.
If there is oxygen on the activated carbon adsorption, sometimes also make the adsorption of the material oxidation reaction.
Therefore, before the use of activated carbon, most of the gas must be removed by adsorption.
Usually remove the gas in activated carbon there are two methods, one method is to use ephedrine or hydrogen sulfide saturated water solution treatment, but this treatment method is too complex, and through these treatments can also cause some other side reactions, so it is not commonly used.
