We all know that carbon black is generally insoluble in water and organic solvents, but here we will introduce a carbon black that can be directly dissolved in water, also known as water-soluble carbon black. Making carbon black more easily soluble in water is a great progress in the carbon black industry. Let me introduce the information of this new type of carbon black.
What is Water Soluble Carbon Black?
Can carbon black be dissolved directly in water? Generally, it is insoluble in water. It usually needs to add specific additives and undergo specific treatment to achieve the effect of carbon black dissolving in water. We call this type of carbon black water-soluble Sexual carbon black. Water-soluble carbon black is a special product among carbon blacks. The biggest difference from other carbon blacks is that it can be well dissolved in water. Because water-soluble carbon black can be better dissolved in water, it is also called hydrophilic carbon black.
Production process of water soluble carbon black
The production method adopted by carbon black manufacturers is to spray the raw material (generally anthracene oil or coal tar) into the burning hot air or natural gas in a closed reaction furnace, and decompose it through thermal oxidation at high temperature. The various properties of the finished carbon black can be controlled by processes such as quenching the flame. Afterwards, a specific filtration system is used to separate the produced carbon black product from the gas fume to make a finished product. After the above-mentioned original production, the original aggregates of carbon black are subjected to special post-treatment to increase the number of surface active groups of water-soluble carbon black particles, increase its own dispersion performance, and produce water-soluble carbon with excellent performance black.
Application range of water soluble carbon black
Judging from the market situation in recent years, the application range of water-soluble carbon black has become wider and wider, and it has been involved in the daily life of the people in various fields. With the maturity of imitation porcelain coating technology, the amount of black mortar is also increasing. Black itself can bring a sense of nobility and solemnity to people. With the high-grade imitation porcelain coating, the application of the exterior wall of buildings has been increasingly popular. sought after.
