Reactive Black KN-B - Introduction

Reactive Black 5, also known as activated carbon black, is a commonly used adsorbent and catalyst. The following is a description of its nature, use, preparation and safety information:

Nature:
1. Appearance: Reactive Black 5 is a black granular solid.
2. Adsorption performance: Reactive Black 5 has a large specific surface area and porous structure, which can effectively adsorb various organic and inorganic substances.
3. catalytic performance: active black 5 can be used as a catalyst carrier, with high adsorption catalytic activity.

Use:
1. Adsorbent: Reactive Black 5 is commonly used in water treatment, air purification and waste gas treatment, which can adsorb organic pollutants, pigments, heavy metal ions, etc.
2. catalyst: active black 5 as a catalyst carrier, commonly used in chemical reactions, such as desulfurization, denitrification, deoxidation and so on.

Preparation Method:
Reactive Black 5 preparation method is more, the most common is the carbonization method and activation method:
1. Carbonization method: carbonization of organic raw materials (such as wood materials, coconut shells, etc.) at high temperatures to obtain carbon black, and then activated carbon black through chemical treatment to obtain reactive black 5.
2. activation method: the carbon black and activator (such as alkali metal hydroxide, chloride, etc.) at high temperature reaction, can be active black 5.

Safety Information:
1. Reactive Black 5 is insoluble in water, but it can absorb hygroscopic substances, and moisture-proof measures should be taken when encountering water.
2. Avoid inhaling Reactive Black 5 dust during use to prevent irritation to the respiratory system.
3. should be operated in a well-ventilated environment, to avoid contact with the fire source, to avoid dust explosion.
4. if accidental contact with skin or eyes, should immediately rinse with plenty of water, and medical treatment.

Please note that the above introduction is for reference only. When producing and using Reactive Black 5, you need to follow relevant specifications and safe operations.
