Shaoyang Zhongcai Manufacturing Co., Ltd., formerly known as Shaoyang Xiangzhicai Chemical Co., Ltd., is a medium-sized production base for fine chemical products in the central and southern regions. It has its own workshop to produce medium chrome yellow, deep chrome yellow, light chrome yellow, lemon yellow, and orange chrome yellow products. The products are strictly produced in accordance with GB/T3184-1993 standards. The following is a brief introduction.
Lead chrome yellow (medium chrome yellow, lemon chrome yellow, deep chrome yellow, orange chrome yellow, light chrome yellow)
Zhongcai Coloring High tech Zhongcai Brand Lead Chrome Yellow is a series of yellow inorganic pigments obtained by deep surface treatment of dichromates, sulfates, soluble lead salts, etc. The main ingredients are lead chromate and lead sulfate, as well as a small amount of components such as aluminum hydroxide and silicon dioxide. By adjusting the ratio of lead chromate to lead sulfate locust, various chromatographic varieties from lemon to orange can be obtained. It has bright colors, strong covering power, high coloring power, solvent resistance, heat resistance, easy grinding and dispersion, and other advantages. Can be mixed with organic pigments for application.
It can be roughly represented by the following chemical formula:
Lemon chrome yellow: 2.5PbCrO4 • PbSO4+xAl (OH) 3+yAlPO4
Light chrome yellow: 3.2PbCrO4 • PbSO4+xAl (OH) 3+yAlPO4
Medium chrome yellow: PbCrO4+xAl (OH) 3
Deep chrome yellow: PbCrO4+xAl (OH) 3
Orange chrome yellow: PbCrO4+xAl (OH) 3
Usage: Lead chrome yellow series pigments are widely used in industries such as paint, coatings, rubber, plastics, etc.
