Introduction
Yellow 180, also known as wet ferrite yellow, is a common inorganic pigment. The following is an introduction to the nature, use, manufacturing method and safety information of Yellow 180:
Quality:
Yellow 180 is a bright yellow pigment with good hiding power, lightfastness and weather resistance. Its chemical composition is mainly ferrite, and it has excellent optical properties, which is often used in dyes and pigments.
Use:
Yellow 180 is widely used in a variety of industrial fields, including paints, ceramics, rubber, plastics, paper and inks, etc. As a high-performance pigment, it can be used to increase the color vividness of products, and has a certain anti-corrosion and protective effect. Yellow 180 is also used in the printing and dyeing industries.
Method:
The preparation of Huang 180 is usually made by wet synthesis method. First, through iron oxide or hydrated iron oxide solution, a reducing agent such as sodium tartrate or sodium chloride is added. Hydrogen peroxide or chloric acid is then added to react, producing a yellow precipitate. Filtration, washing and drying are carried out to obtain yellow 180 pigment.
Safety Information:
Avoid inhalation or contact with yellow 180 particles. Appropriate protective measures such as gloves, masks, and safety glasses should be worn.
Try to avoid swallowing or accidentally ingesting yellow 180 pigment, and if discomfort occurs, you should seek medical attention immediately.
Avoid mixing Yellow 180 pigment with strong acids, bases, or other harmful chemicals.
When storing and using Yellow 180 pigment, it is necessary to pay attention to fire and explosion prevention measures, and keep away from fire sources and high temperatures.
