Product Description

　　Nut shell activated carbons are black grains in indefinite forms refined from nut shells including Apricot shells, walnut shells and jujube shells through carbonization, activation and catalyzing with superheated steam. Nut shell carbons have good abrasive resistance, high absorption and high intensity and can be regenerated. As an economic and durable products, nut shell activated carbons are widely used in living, industrial, liquid-phase absorption, water purification and air purification, Especially, they are applicable to power plants, petrochemical, sewage treatment plants, oil refineries, textile dyeing and printing, food and beverage, pharmaceutical water, electronic high purity water, drinking water and industrial water reuse.

　　Package and storage:

　　Tips: the following 2 points should be paid attention to during purchasing:

　　1. Activated carbons should be tight packed. As there are various organic macromolecular substances suffused in the air more or less, and with time passes by, these substances will be absorbed by activated carbons, and the absorption performance of activated carbons will be reduced as they have already absorb the substances in the air. Therefore, activated carbons with high absorption capability should be tight packed in order to prevent external interference.

　　2. Nowadays, the semi-finished products of activated carbons, “carbonized materials” are sold in the market simulating finished activated carbons. Since activation is the most important process during which pre structures are generated, only “activated” carbonized materials can regarded as finished products with absorption capability, and these fake products without absorption capability make consumers suffer. These fake activated carbons have slight metallic sheen, and are smoother, whiter, harder and heavier than real activated carbons as they do not undergo activation and pore forming process. Among these fake products, a large portion of them are produced by low-quality raw materials and diatomite; therefore they are inactivated substances with low carbon content. These carbons are whiter and whiter, the grain is intensive and longer in size. When they are collided, they can make clear sounds like knocking ceramics. And if you break them apart, you will find there are small white particles in the fracture surface. We hope that you remember these features to avoid purchasing fake activated carbons.

　　The grain size, PH value and ethylic acid absorption of our nut shell activated carbons can be produced based on users’ demand, and we welcome you to purchase.
