Description

It is a mixture of lead monoxide and lead dioxide. Relative density 9.1. Insoluble in water and alcohol, soluble in nitric acid (in the presence of hydrogen peroxide), glacial acetic acid, hot hydrochloric acid and hot lye. It has high corrosion and rust resistance and high heat resistance, but not acid. It has great diffusivity in grease and strong covering power. It is an alkaline pigment, which can form lead soap with free fatty acid in the paint base, and has strong covering power and adhesion after painting. It reacts with hydrogen sulfide to generate black lead sulfide (PbS). When exposed to air, it turns white due to the formation of lead carbonate. When heated to 500 ℃, it decomposes into lead monoxide and oxygen. There is oxidation. poisonous. Used as raw materials for analytical reagents, paint pigments and glass Inorganic red pigment. The paint industry is used to manufacture anti-rust paint and steel protective paint, with good anti-rust performance. The glass lining industry is used in the manufacture of enamel and optical glass. The ceramic industry is used to make ceramic glazes. The electronics industry is used to manufacture piezoelectric components. The battery industry is used for the production of accumulators. The mechanical industry is used for metal grinding. The organic chemical industry is used in the manufacture of dyes and other organic synthetic oxidants. Can be used for rubber coloring. The pharmaceutical industry is used in the manufacture of ointments, plasters, etc.
