Today, I will introduce a very common board mesh material - a fingerprint-resistant plate. This article will introduce the following aspects: the origin, characteristics, and types of fingerprint-resistant plates
1. The origin of fingerprint-resistant plate
Anti-fingerprint treatment was originally designed to meet the requirements of users in the field of home appliances. In the production process of home appliances, many parts are touched many times by workers due to the needs of the process, and the sweat stains on the hands of the workers will pollute the surface of the parts and affect the appearance. Therefore, a fingerprint-resistant plate has been researched and developed.
2. Features of fingerprint-resistant plate
Except for some special processes, the anti-fingerprint treatment technology used coatings containing hexavalent chromium in the early days. With the increasingly strict environmental regulations, the hexavalent chromium technology was gradually replaced by the trivalent chromium technology and the chromium-free technology. Chromium-free technology not only has the corrosion resistance of chromium-containing technology, but also has the versatility that chromium-containing technology does not have. Widely used in home appliances, electronics and construction markets.
3. Types of Fingerprint Resistant Boards
One is that after the galvanized sheet is passivated, an organic coating (fingerprint-resistant film) is applied on the passivation film, and the coating method is mainly roller coating.
The other type is to add organic resin and colloidal silica to the passivation solution of galvanizing. After the galvanized strip passes through the passivation tank, a composite coating with corrosion resistance and fingerprint resistance is formed on its surface. Coating methods mainly include electrolytic coating and roller coating. At home and abroad, the first process is generally used to produce fingerprint-resistant boards.
