Problems solved by technology

Since the test process involves multiple weighing and multiple sample transfer steps, the solvent volatilization and dripping during the process also affect the accuracy of the experimental results, and the detection error is relatively large
[0005] Therefore, there is still a lack of a technical means to characterize the solubility of substances attached to the substrate, so as to facilitate rapid program screening and finalization

Abstract

The invention discloses a method for representing dissolving power of solvent. The method includes the steps that a spray room environment is set, then a substrate is sprayed with paint with even film thickness in the mode of static spraying, a paint sample is obtained through flash-off, then the center of the paint sample is sprayed with the solvent through air spray gun equipment, the substrate is subjected to horizontal flash-off and then baked, a paint sample dissolved by the solvent is obtained, and finally, according to the reduced area region of paint in the center of the paint sample dissolved by the solvent, the capacity of the solvent in paint dissolving is represented. With the method, the technical problem that no methods are provided for representing the capacity when substances on a substrate are dissolved is solved, compared with the prior art, the accuracy of representation is improved, representation errors are reduced, and the screening time for samples is shortened.

Description

technical field [0001] The invention relates to a method for characterizing chemical properties, in particular to a method for characterizing the dissolving ability of a solvent and a method for testing the dissolving ability of a solvent. Background technique [0002] Solvency refers to the ability of a solvent to dissolve a solute under certain temperature / pressure conditions. In industry, known judgments on the solubility of solvents include: the concentration that can be achieved by dissolving a certain solute; The higher its solubility; the compatibility with other solvents, that is, the compatibility with other solvents in the formula, etc. [0003] Among these test methods for evaluating solvent solubility, such as: Kauri resin-butanol dissolution test method, constant viscosity method and dilution ratio method, etc. [0004] For substances applied to products, to judge the solubility of a certain solvent to the substance, the commonly used means are: soaking method...
