When the spectrum of a pure compound is measured in a series of different solvents, the data obtained, including the intensity and the wavelength position of the absorption band, often vary with the change of the solvent. Depending on the nature of the solute and the solvent, sometimes a chemical reaction may occur between the two, and a complex may also be formed. The dissociation constant and tautomeric equilibrium of the solute are also related to the solvent, so that different solvents can produce very different spectra. Therefore, when comparing or checking the spectra of compounds, it is better to use the same solvent. If the solvents used are different, the influence of the solvent should be considered when analyzing the spectra. In addition, it is sometimes possible to infer the transition type to which a certain absorption band belongs from the difference in different solvents.

The secondary film formation includes various pigments, extender pigments, and anti-rust pigments. Pigments provide color and hiding power for the paint film, and improve the performance and decorative effect of the paint. Pigments with good weather resistance can increase the service life of the paint. Extender pigments can be applied to the thickness of the paint film, using the properties of its own “flaky, needle-like” structure. After the accumulation of the pigments, it forms a scale-like paint film, which improves the service life of the paint film, and improves the waterproof and anti-rust effect. . The anti-rust pigment has its own physical and chemical anti-rust effect to prevent the surface of the object from being corroded by the atmosphere and chemicals, and the metal surface is rusted. ④熔体流动性要好
