Purpose
1. Lead chrome green is the main coloring pigment in coating industry, and most green paints are made with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Due to the chromium yellow in the composition, attention should be paid to the toxicity of lead. Lead chrome green contains iron blue and lead chromate as oxidant. Therefore, when dust meets Mars, it may spontaneously ignite, so it should not be accidentally dried and crushed. After combustion, the lead chrome green completely lost the characteristics of green pigment and turned into a dark brown yellow substance. In addition, when making nitrocellulose lacquer, the rolling process is not directly rolled with lead chrome green, but after the lead chrome green is grind into the pulp, the process is prevented from burning at the time of rolling.
2. Used in metallurgy, ceramics, refractories, pigments and organic synthesis catalysts.
3. Used as analytical reagent and catalyst.
4. It can be used as a filler for coloration, wear resistance and corrosion resistance of adhesives and sealants. It can also be used as colorant for enamel, ceramics, artificial leather and building materials; Organic chemical synthesis catalyst; Light resistant coating and special ink for printing banknotes.
5. as a coloring agent for cosmetics, it is mainly used for eye cosmetics, but not for oral and lip cosmetics. It is not recommended for facial cosmetics and nail polish.
6. Chromium trioxide is one of the main components of silver plating brightening solution. The newly prepared chromium trioxide is an important raw material for the preparation of chromium fluoride and chromium bromide.
