Standard mass detection method in painting process

The quality inspection in the coating process is of great significance for controlling the coating quality, saving coating expenses, and obtaining high-quality coating products. The above-mentioned testing of the performance of the coating product itself has a great relationship with the coating operation, and the quality testing during the coating process also directly affects the quality of the coating. The standard testing methods used in the coating process are:

(1) GB1727-92 general preparation method of paint film;

(2) GB1758-89 (79) Determination of paint usage;

(3) GB1726-89 (79) Determination of coating hiding power;

(4) GB1764-89 (79) Determination of coating thickness;

(5) GB1750-89 (79) Determination of paint leveling;

(6) Determination of GB9264-88 color paint sagging;

(7) GB1728-89 (79) Determination of drying time of paint film and putty film;

(8) GB1762-89 (80) Determination of paint film back tackiness;

(9) GB1757-89 (79) Determination of brushability of coating paint;

(10) GB1759-89 (79) Determination of shrinkage rate of cloth after painting;

(11) GB1760-89 (79) Determination of increase in tensile strength of cloth after painting.
