1、 Purpose:

The strength, hardness, and adhesion of the coating are important physical properties of the coating, and their size directly affects the importance of the coating Performance, such as wear resistance; Wear resistant graininess; Abrasion resistance; Scratch resistance, impact resistance, and coating hysteresis The strength and hardness of the coating film are necessary indicators for evaluating the performance of the coating due to factors such as retention and difficulty in cleaning. Use this device The instrument can conveniently and comprehensively evaluate the physical properties such as coating strength, hardness, adhesion, etc., so the purpose of this instrument is The strength, hardness, and adhesion of the coating are characterized by the anti penetration ability of the paint film sample coating when scratched by a scratch needle The magnitude of the force.

This HS-NG-1 floor scratch resistance tester is designed for implementationGB9279-88The developed equipment is the material condition for the implementation of this national standard.

2、 Structure and working principle of the instrument:

AStructure (see attached figure)

BWorking principle

This instrument mainly consists of a needle holder and a worktable. The needles on the needle holder ensure that they act vertically on the coating template

The template is fixed on the test bench on the workbench and can be moved horizontally; horizontal movement can be motorized or when the power is turned off After manual operation）.
