Applications: The Pencil Hardness Tester is Applicable to determine coating and film hardness. It is suitable for labs and building sites. It also can examine the hardness of coating film on any direction. Scientific and rigorous testing of the important properties of the coating film. Test the hardness of coating film Manufacturing paint Pencil Hardness Tester Coating Hardness Tester (500, 750, 1000G 3 in 1) with 13 pencils Product desciption The instrument is mechanical. Three point (Two wheels and a lead core) contact the tested surface always to ensure the pencil and the tested surface forms the angle of 45 degrees, so as to push the movement of the instrument, to complete the testing process. Featured overall upgrade of production technology more bright carts, beautiful and generous overall body. Two wheels are stainless steel and bearing design, beautiful appearance, flexible use, long life. Free testing of 500g, 750g, 1000g Measurement Angle: 45°(Between Pencil and Measured Surface) Three Touch Points: Two Wheels, A Pencil Core Pencil: 6B-B,HB,H-6H Total 13 pencils Material: Stainless steel wheels and bearings.
Coating is the coating hardness (tu) industry manufacture, coating used for quality that will measure indicators. Pencil scratch method of coating hardness test is widely adopted since the eighty s by the international test methods.
The instrument is according to the national standard "film pencil hardness measurement" GB6379-86-2, article 3 of manual operation and the design and manufacture. Instrument can be used in the laboratory, also can be applied to the construction site, and can be in any direction on the identification on the coating hardness.
The structure and working principle Instrument for mechanical, three contact surface to be tested (for round 2 o 'clock, a bit of lead) always guarantee a pencil with 45 ° Angle measured surface formation, forcibly horizontal drive instrument movement, can complete the testing process, determination of coating's ability to resist deformation.
3. Use requirement
1. GB1279-79 "general preparation method of coating, the preparation of test pieces of 3 pieces, for smooth tin plate commonly 50 * 120 * (o. 2-0.3 mm, or products shall be separately stipulated by the substrate and size.
2. The test conditions according to the requirements of product standards or construction conditions.
Suggest at least three specimens location above, average. Hardness of the series, with a pencil from soft to hard 4 B, 6 B 5 B 3 B 2 B B HB H H, 2 H, 3 H 4 5 H, 6 H (13).
This set comes with a trolley car for pencils, weights for the car, a set of pencils of a range of hardnesses, a blade and an eraser -- exactly as shown in the photos. The test to determine the pencil hardness of coatings is really simple and this set provides you with more than enough tools to get repeatable results.
