Method for detecting latex paint film and construction odor

Abstract

The invention relates to the field of paint film odor detection, in particular to a method for detecting latex paint film and construction odor. The present invention comprises the following steps: Step 1: Clean and dry the odor measuring cabin and glass plate with distilled water and dry them for use; Step 2: Test the smell of roller coating construction: carry out plate making, then put the glass plate into the odor measuring cabin and close it tightly The hatch; then open the hatch and test with an odor tester; Step 3: Paint film odor test: fully open the hatch of the smell test cabin, then close the hatch of the smell test cabin again, and let it stand for at least 1 hour ; Then open the hatch and test with an odor tester; Step 4: Repeat the paint film odor test in Step 3 for 2-3 times, with an interval of at least 2 hours between each test; Step 5: Result evaluation. The invention can objectively and truly reflect the size of the smell emitted by the paint film during construction, and eliminate the uncertainty in the detection process.

Description

technical field [0001] The invention relates to the field of paint film odor detection, in particular to a method for detecting latex paint film and construction odor. Background technique [0002] During the preparation and construction of latex paint, the smell of the latex paint will be further amplified due to the addition of different emulsions and the further atomization of the latex paint during the spraying process. The existing detection method - Nippon Paint's 2008 patent (CN101118231A) mainly adopts the subjective judgment method of people, uses statistical methods, samples through many people, and further compares the size of two kinds of smells to people. This detection method lacks objective judgment basis and cannot intuitively reflect the size of the smell; at the same time, too few samples are selected, the statistical convincing power is not strong, and people's subjective judgment is affected by many uncertain factors. It is not exactly the same, and it i...

This detection method lacks objective judgment basis and cannot intuitively reflect the size of the smell; at the same time, too few samples are selected, the statistical power is not strong, and people's subjective judgment is affected by many uncertain factors. It is not exactly the same, and it is even more impossible to distinguish samples with similar odors. At the same time, the 3h odor dissipation mentioned in CN 101118231AZ has no reasonable indicator characterization, so it is full of many uncertainties and also affects the accuracy of the results. At the same time, the judgment is only limited to the finished paint and the paint film measurement in the laboratory, and the more important construction environment has not been paid attention to. Therefore, the current judgment method has many limitations.
