Therefore, the final interior wall coating The quality of the paint depends on the entire coating system consisting of putty, primer and topcoat. In addition, it is also related to the construction conditions, such as coating thickness, paint-water Dilution ratios, etc., they have a significant impact on the quality of the final coating system. Description of index number. 1 --- Substrate (wall); 2--- putty; 3 --- Primer (1); 4 --- Topcoat (2 coats). Figure 1 Typical interior wall coating system There is no standard field test method in the worldwide market to check the performance of the entire coating system. Currently, the so-called "on-site "Test method" mainly relies on methods such as visual inspection, fingernail scratching and touching. These methods are very subjective, because even for the same wall Different personnel may obtain different results with different topcoat systems, and these results are not repeatable. Therefore, the standard test methods provided in this document The method is used for on-site quality assessment of wall coatings. Using these standard test methods can help distinguish between good and bad interior paint coatings. On-site quality assessment of paints and varnishes for interior wall coatings experiment method1 ScopeThis document specifies two field test methods for evaluating the quality of interior wall coatings [i.e. field cleanability (stain removal) test and field Field wet scrub resistance test]. This document applies to white and light-colored coatings with tristimulus value Y10 greater than 25.The tristimulus values were obtained by coating on a black substrate Measurements were obtained on specimens prepared from the coating. The cleanability test is suitable for evaluating the performance of paints with a pigment volume concentration (PVC) between 18% and a critical pigment volume concentration (CPVC). coating quality. The field wet scrub resistance test method is suitable for evaluating the coating quality of coatings with PVC concentrations close to or higher than CPVC.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text.
