Introduction: The instrument is used to determine the ability of various coating films to adhere to the surface of the object. Film adhesion tester structure principle: The main drive part is composed of hand wheel, sprocket, spiral helical gear, when turning the hand wheel, the worktable moves left and right, and the needle is drawing a circle; the drawing head part is composed of the following two components Construction; Double-headed square screw to adjust the head up and down; from the sliding dovetail and a screw can drive the needle dovetail connection to adjust the drawing diameter. The workbench part is connected with a half nut which can be lifted at one end and the lead screw to drive the worktable to move back and forth. The workbench has four nuts and two pressure plates to press and place the test piece. The base part is used to support the table and the head. Technical Parameters: 1. Describe the diameter of the figure: 0~10.5 mm 2, the table effective area: 50 mm * 100 mm 3, increase the weight in four, 500 grams one, 200 grams two, 100 grams one 4. The needle can be replaced easily with 808 brand squeegee and it can be used less than 5 times. 5, the effective travel of the table is not less than 80 mm. Instructions: 1. Prepare templates as required. 2. Check that the steel needle is replaced with a new steel needle as soon as it is used. The needle tip is approximately 3 mm away from the work surface. 3. Adjust the eccentric position of the needle tip according to the required drawing diameter and then tighten it with screws. 4. Place the prepared film with the film side up and press it on the workbench with a pressure plate. 5. Add weights to the weight plate as required. 6. Lift the movable half nut to move the table to the outer end and lower the movable half nut. 7, toggle pressure rod, so that the needle tip and film surface contact. 8. Shake the handwheel, then the steel needle draws a spiral pattern on the sample plate. According to the pattern, the adhesion of the coating film can be judged as excellent, good, medium, poor, and poor.
