To deal with a paint, only to understand its chemical composition, but also can not be arbitrary it is the essence of the material. As the same component of lithopone is a pure, bright, the other is gray or yellow. The same yellow, a crystal with bright tone, another dark. Used as a pigment, in addition should be familiar with the chemical composition, more necessary should be familiar with its physical qualities, such as crystalline morphology, refractive index, color, draw of granularity distributing) and Yuehe condescend and so on. Pigment production and production skills should be the heart: such as the formation and disposal of pigment crystallization, washing degree, water soluble salt content, in the dry process of impurities, whether through the disposal of additives, etc..
One of these premises is not necessarily affected by the use of a tremor in the paint. Even though the pigments in the water soluble salt, may make the dry paint film late, because it is a catalyst for pigment. Can also lead to the erosion of the underlying metal erosion, etc.. Pigment production is not necessarily to contain any impurities in the dry color. Now general inorganic pigment guess, nonferrous metal compounds are more, the toxic metal is more, such as mercury, copper, chromium, lead. Pigment manufacturing process to understand the orders defense to penetrate the human body, these pigments are used to enhance the door steps, in order to avoid poisoning of workers. It is necessary to further study the toxic paint to replace these valuable and toxic metal compounds.
