Nowadays, it has become a trend to use fingerprint-free processing technology for stainless steel plates. This is mainly because the fingerprint-free process can effectively prevent the oil stains and sweat on people's fingers from corroding the surface of the color stainless steel plate, thereby prolonging the service life of the color stainless steel plate. Greatly extended, don't worry about leaving fingerprints on the surface of the stainless steel plate to affect the appearance.
First of all, the anti-fingerprint effect of the anti-fingerprint stainless steel plate does not mean that the stainless steel surface cannot print fingerprints, but that the fingerprints after fingerprints are lighter than ordinary stainless steel surfaces, and are easier to clean, and will not leave any stains after wiping.
Anti-fingerprint is achieved by coating the surface with a layer of hydrophobic material film, so that it is difficult for stains to adhere like lotus leaves, and the attached objects cannot stand and spread on the surface, so as to achieve the purpose of anti-fingerprint. Fingerprint effect.
The inability of the adherend to stand and spread on the surface is an important factor to achieve anti-fingerprint. This involves reducing the surface tension of the contacting surface in order to make it difficult for the adherend to stand and spread on the surface. Surface tension is a manifestation of molecular force, which occurs when a liquid and a gas are in contact, between the contact edges of the two, and is determined by the special state of the liquid molecules on the surface. Due to surface tension, the surface of a liquid always tends to shrink as much as possible (the pressure around the liquid is consistent and tends to the same point), so small droplets in air tend to be spherical.
Simply put, the effect of surface tension is to shrink the liquid surface, which is related to the properties of the liquid and has nothing to do with the size of the liquid surface. Surface tension can also be regarded as surface free energy, which can be approximately regarded as the active state of the surface. The greater the surface tension, i.e. the greater the surface energy, the more active the surface and the easier it is to stick to other objects.
The fingerprint-free process of color stainless steel plate refers to coating a protective layer of transparent colorless to pale yellow liquid on the surface of color stainless steel. It is firmly bonded together to form a transparent hard solid protective film layer.
The surface of the colored stainless steel plate is treated with professional fingerprint-free technology, which increases the aesthetics and durability of the metal decorative plate. defile. Fingerprint-free technology changes the previous problem of leaving visible fingerprints when touching stainless steel surfaces. In addition, the fingerprint-free technology can make the color stainless steel surface glossier and reduce the time of daily maintenance. The color stainless steel plate treated by the fingerprint-free process brings great benefits.
1. Easier to clean
It is easier to clean the surface stains, no metal cleaning agent is needed, and some chemicals will make the surface of the stainless steel plate black; and it is not easy to get fingerprints, dust, and has a fine hand feeling, which has a super fingerprint anti-fouling effect.
Second, not easy to scratch
The transparent film layer without fingerprints can protect the metal surface from being easily scratched, because the gold plating on the surface has good oil film, high hardness, and is not easy to peel off, chalk and yellow.
3. Better texture
If the color stainless steel plate is processed by the fingerprint-free technology, the appearance texture will be stronger, oily and moisturizing, the hand feeling will be softer, and its good metal texture will be better preserved.
4. Better Decor
The fingerprint-free treatment of colored stainless steel sheets can change the icy and veneer properties of the metal, making it look warmer, more elegant, and more decorative.
5. Enhance anti-rust ability
After the color stainless steel plate is treated without fingerprints, its anti-rust performance will be enhanced, and a protective film can be formed on the surface of the stainless steel plate, which can effectively block the external corrosion inside the metal and greatly improve the service life of the stainless steel plate. extension.
However, there are also caveats. Once the color stainless steel plate has been processed by the fingerprint-free process, it can no longer be welded and stretched. Because the protective film without fingerprints will turn black when exposed to high temperature, which seriously affects the beauty of the color stainless steel plate.
