QGZ-24 hours paint film drying time tester tester paint drying speed

Barang Preorder/Indent Estimasi 15-20 hari. DIY Supplies : ELECTRICAL OnePurpose: QGZ-( 6, 12, 24The film drying time tester is a new type of instrument for measuring the drying time of the coating. The coating film formed by the various coatings can automatically and continuously display the states of various stages of the drying process in the form of drawing a circular track, and can visually analyze and observe the time for each stage. Is an ideal instrument for coating detection and coating formulation research. II.Main structure and working principle (reference sketch) Instrument by switch( 1), Hood ( 2Motor (in hood), support( 3), connecting the shaft ( 4(rotating arm)( 5(Scratch needle)( 6(test board)( 7), time dial ( 8Composition. The principle is: Put the instrument on the prepared coating test plate, turn on the power supply, synchronous motor, and pass through the connecting shaft( 4) Drive with scratch needle( 6) Rotary Arm( 5). (the arm is free to droop) for a week /6Hours, a week /12Hours, a week. /24The speed of the hour is Shiting, and the needle is drawn on the coating with a diameter of 100mmThe circular trajectory. As the film gradually dries with time, the plough marks of the scratch needle on the film change from wide to narrow, from deep to shallow, and finally can not be scratched, thus showing the whole process of drying. Three.Main technical parameters: 1, Power Supply: AC220V· 50HZ 2, Measurement error: + 0.5% 3, The diameter of the circular trajectory drawn by the needle: 100mm 4, Needle End part RFor: 0.25, 0.5, 1.0, 1.5mm four,Requirements for use: 1, Test board: Glass Plate ( 200*200*2- 3). or smooth tinplate board ( 200*200*0.2- 0.3) or agreed test board material. 2Test environment: press GB1727- 79Requirements, painted plate placed horizontally, avoiding airflow, no direct sunlight, at temperature 25± 1° CThe relative
