Overview of QHZ Coating Film Scratch Tester

JinKeLian QHZ Coating Film Scratch Tester, as the name suggests, uses the scratch test method to test the surface hardness of the paint film. Hardness is one of the important properties of the coating. Relevant national and international standards also stipulate the Hardness test methods and hardness standard levels. This QHZ coating film scratch Tester is a standard coating film scratch Tester designed according to the standard. It is an electric Dial-Type Hardness Tester with a compact structure design and a scratch length of up to 60mm.

Coating film strength, hardness, adhesion, etc. are important physical properties of the coating film, and their size directly affects the important performance of the coating film, such as: abrasion resistance; abrasive resistance; scratch resistance; impact resistance and The retention effect of the coating film and the difficulty of cleaning, etc., so the strength and hardness of the coating film are the necessary indicators to evaluate the performance of the coating. JinKeLian QHZ Coating Film Scratch Tester can conveniently and comprehensively evaluate the physical properties of the coating film such as strength, hardness, adhesion, etc. The strength, hardness and adhesion of the coating can be characterized by the anti-penetration ability of scratching time.

JinKeLian QHZ Coating Film Scratch Tester is a special equipment developed for the implementation of GB9279-88, which is the condition for the implementation of this national standard.

Principle of coating scratch Tester

JinKeLian QHZ Coating Film Scratch Tester is mainly composed of a scribing frame and a workbench. The scribing needles on the stylus frame are guaranteed to act vertically on the coating film sample (the sample is fixed on the test bench on the workbench, and can be horizontally or vertical movement; lateral movement can be motorized or manual after power off, vertical movement is manual).

After the power is turned on, the red indicator light of the power switch is on, indicating that the instrument is powered on. At this time, if the return switch is in the experimental state, the worktable moves from right to left, and the needle touches the sample during the "experiment" stroke; during the return stroke (the return switch is turned back to the "return" state), the worktable moves from left to right , the stylus is raised without touching the sample, and the weight added on the stylus frame can be changed to measure whether the paint film can be scratched under different weights, and the minimum weight required to scratch the paint film can be used to judge The value of the scratch resistance of the coating film.
