| titleOfInvention | A detection method for risk assessment of yellowing of chemical building materials |
| abstract | The application provides a method for detecting the risk of appearance pollution caused by the precipitation of migratory and easily yellowing organic substances in chemical building materials, which is characterized in that it at least includes the following steps: a) contacting the solvent with a solid containing the chemical building material to be tested to obtain leachate; b) aging the leachate obtained in step a) to obtain the aged leachate; c) measuring the chroma of the aged leachate; the chroma of the aged leachate reflects the risk of yellowing of chemical building materials; or, the The evaluation method for the risk of yellowing of chemical building materials includes the following steps: apply the putty on the solid surface containing the chemical building material to be tested, place it for no less than 3 days and then perform accelerated aging, then measure the color change of the putty surface, and the color change of the putty surface The size reflects the risk of yellowing of chemical building materials. |
