Note: The pencil hardness is the weight of pencil pressure on the measured object, not the direct weight of the car and weight   Use:     Coating hardness is the paint manufacturing, paint use (painted) industry to determine the quality of the necessary indicators. Pencil scratch test commonly used test methods to test the hardness of the coating. China has also promoted this test method in the development of coatings and in industrial production. The instrument can be used in the laboratory, but also apply to the construction site, and in any direction on the coating hardness identification.   Structure and working principle:     Instrument for the mechanical, three-point contact with the measured surface (two for the wheel, a point for the lead) Always ensure that the pencil and the measured surface angle of 45 °, the level of force to promote the instrument movement, you can complete the test process, the determination of coating Ability to resist deformation.   Requirements: 1. GB1279-79 "Preparation of paint film," the preparation of three pieces of test, usually a smooth tinplate 120 * 50 * (O.2-0.3) mm, or the substrate and the size of the product otherwise specified. 2.
