Corona Discharge Test Pen

The corona test pen detects the surface tension of materials by discharging electricity through its tip. The pen fluid spreads evenly on surfaces that meet the required dyne level, while it contracts into droplets on surfaces that do not meet the standard. It is used for rapid verification of surface treatment effects before printing or coating on plastic films and metal foils.
Selection
When selecting, it is necessary to match the material's dyne value range, commonly 38-56 mN/m. The ink capacity of the pen affects its service life, and the pen tip material must be wear-resistant. A working environment humidity below 65% can prevent misjudgment, and accuracy should be verified regularly using standard test films.

Pencil Hardness Tester for Rapid Evaluation of Coating Surface Hardness
The pencil hardness tester is a tool used for rapidly assessing the relative hardness of coating surfaces through standardized scratch tests. It employs a series of pencil leads with known hardness levels, which are drawn across the coating under a fixed load and angle. The hardness grade, ranging from 6B to 9H, is determined based on whether a permanent scratch is produced.

It involves using a series of pencils with known hardness levels to scratch the coated surface under fixed conditions. The hardness grade of the coating is determined by observing whether permanent scratches are produced.
Application of Film Pencil Hardness Tester in Coating Scratch Resistance Testing
The paint film pencil hardness tester is an instrument used to evaluate the scratch resistance of coatings. It works by scratching the surface of the coating with a pencil of known hardness under a fixed load, and then assessing the hardness grade based on whether scratches are produced.
Classification standards for determining the hardness of coatings using a pencil hardness tester.
This article introduces the method of measuring the hardness of coatings using a pencil hardness tester. It involves using pencils of varying hardness to scratch the coating and observing whether scratches are produced to determine the hardness grade, ranging from 6B to 9H.
Key Operational Points and Influencing Factors of Pencil Hardness Method for Determining Coating Film Hardness
The pencil hardness test is a method used to evaluate the scratch resistance of a coating by making marks on the paint film with pencils of known hardness. During the operation, a uniformly cured sample is prepared, and calibrated pencils are used to make marks at a 45-degree angle with a fixed force, aiming to identify the highest hardness grade that does not scratch through the paint film.
How to Select a Pencil Hardness Tester? A Comprehensive Guide from Principles to Practical Application
When selecting a pencil hardness tester, focus on three key points: choose manual or automatic based on standards, use specialized testing pencils, and ensure the instrument can fix a 45-degree angle for uniform force application to achieve accurate and reliable results.
