TRUIT TR 5105/1 Benchtop paint film Pencil Hardness Tester

Introduction

TR 5105/1 desktop paint film pencil Hardness Tester is a manual pencil Hardness Tester, which is a commonly used coating film hardness measurement equipment. It uses pencil scratches to evaluate the hardness of the coating film. It is equipped with three different test loads of 500g, 750g and 1000g, and the appropriate load can be selected for testing according to needs. By applying a certain pressure on the surface of the coating film, use a standard pencil to scratch, and evaluate the hardness of the coating film according to the degree of damage of the scratches. The instrument is simple to use and easy to operate, and is suitable for the application of rapid evaluation and quality control of coating film hardness in the paint, varnish and coating industry.

The instrument can be used in the laboratory or on the construction site, and can identify the hardness of the coating film in any direction.

Principle

The instrument is mainly composed of a pencil stand and a test stand. The pencil stand and the column are composed of a four-link structure, which ensures that the weight of the weight acts vertically on the intersection of the pencil lead and the test stand, and makes the pencil and the test stand form a 45° clip. The angle remains unchanged, the test bench can move horizontally and vertically, use it to fix the paint sample, and make the sample slide towards the direction of the scratch, and the pencil will draw the corresponding track on the test piece. Use different pencils to draw different marks, based on which the hardness value of the coating film can be determined.
