The use of marker pens
Thread Content
For precious metals such as titanium, zirconium, and nickel, what kind of marker should be used to apply markings during the manufacturing process? ? ? Is there any basis or reason for it?
The requirement is for marker pens that are free of fluorine and chlorine; I’ve been in this business for 30 years and have never seen any like them
When manufacturing precious metals, to ensure the durability and visibility of markings and to prevent contamination of the metal surface, it is recommended to use markers that are resistant to wear and have good water resistance. Therefore, the following types of marker pens can be chosen: 1. Non-fading oil-based marker pens: The ink in oil-based marker pens usually contains oily components that allow them to form a stable coating on metal surfaces, one that does not easily fade away. 2. Water-resistant water-based markers: The ink in water-based markers is usually a mixture of water and pigments, giving them good water resistance; even when exposed to humid environments, the markings remain clear and durable. 3. Markers specific for metals: Some manufacturers offer special markers designed for use on metal surfaces. These markers generally have better wear and water resistance, allowing them to create even and clear marks on metal surfaces. Different materials may have varying compatibility levels with different types of marker pens; therefore, it is recommended to conduct small-scale tests before choosing a marker pen to determine the type that is most suitable for that particular metal material. .
