  1. In the process of selecting coal-based columnar activated carbon, attention should be paid to the selection of "activated" finished products, because now there are many counterfeit semi-finished products on the market, causing consumers to suffer a lot. The activation process is an important part of the activated carbon manufacturing process.

 

Only through the "activation" process can it become real activated carbon, so the products on the market that have not undergone the activation process have almost no adsorption function.coconut shell activated carbon for gold recovery So how to distinguish? From the appearance point of view, the color is white, and from the hand feel, it is harder than the fine coal columnar activated carbon.

 

  1. Looking at the amount of packaging, the higher the iodine value of coal-based columnar activated carbon, the lower its bulk density, and correspondingly, the lower the weight per unit volume. Therefore, when we compare the quality of two or more coal-based columnar activated carbons, we can use the same volume of coal-based columnar activated carbon products to compare their weights. The lighter the weight, the better the quality.

 

The coal columnar activated carbon is easy to adsorb substances in the air because of its adsorption function, so in order to ensure that its adsorption effect is not damaged, it needs to be sealed and packaged. The packaging of the fine coal-based columnar activated carbon on the market is sealed.

 

  1. From the appearance of coal-based columnar activated carbon, we can only tell the size of the coal-based columnar activated carbon in a simple way, but not the quality and true or false. Therefore, we need to do a small experiment on the coal-based columnar activated carbon products we have purchased to make a simple distinction, which is to add water to see bubbles. Coal-based columnar activated carbon can adsorb and purify waste gas and wastewater, relying on its own internal pores.

 

The more developed the pores, the stronger the adsorption capacity of the coal-based columnar activated carbon, and the more pores, the more air is stored inside.buy bulk activated carbon pellets Therefore, when the coal-based columnar activated carbon is added to clean water, a large number of bubbles will appear and it will last for a long time. Generate bubbles. The higher the iodine value of coal-based columnar activated carbon, the longer the bubble generation time and the more intense the bubble generation.

 

  1. Look at the product quality inspection report attached to the manufacturer. Under normal circumstances, regular activated carbon manufacturers have their own product quality inspection departments, and the finished product packaging will be accompanied by product quality inspection report instructions.
