【Scope of application】： According to the national standard GB9779-2015 “Multilayer Building Coatings”, the CGK-2 initial drying crack resistance tester is suitable for the initial drying and crack resistance test of architectural coatings and indoor and outdoor construction putty under the condition of specified wind speed. [Meet the standard]: 1. GB 9779-2015 “Multilayer Building Coatings” 2. JG/T 24-2000 Synthetic resin emulsion sand wall architectural coating [Instrument features]: The JL-CGK-2 initial drying crack resistance tester has a test plate parallel to the direction of air flow in the wind tunnel, and after starting the axial flow fan, the air speed is controlled within 3±0.3m/s by the air volume control device. The coated test plate is placed on the test plate frame in the wind detection tunnel. Adjust the drying control time according to the product requirements, and after the time is up, the machine will automatically stop and test whether there are cracks on the surface of the plate. 【Technical Parameters】: 1. The wind speed control is: 3±0.3M/S 2. Working voltage: 200~240V 50HZ 3. Laboratory temperature: 23±2°C, relative humidity 50%±5%
