Can carbon black be directly dissolved in water? Generally, it is insoluble in water, and it usually needs to add specific additives. This type of carbon black is called water-soluble carbon black. Water-soluble carbon black is a special product among pigment carbon blacks. The biggest difference from other carbon blacks is that it can be well dissolved in water.
The production process of water-soluble carbon black is basically similar to that of general carbon black:
The raw materials of carbon black are mostly oils, which are injected into the burning hot air or natural gas through a device in a closed reaction furnace, and then decomposed by thermal oxidation at high temperature. The various properties of the resulting carbon black products can be controlled by processes such as quenching the flame. Afterwards, the produced carbon black product is separated from the gas fume using a specific filtration system 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.
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 high-grade imitation porcelain coatings, the application on building exterior walls has been increasingly popular. sought after.
