Stainless steel protective film is a large number of stainless steel consumables used in the field of stainless steel processing, production and circulation. Generally, stainless steel materials that have undergone surface processing basically need to be protected by stainless steel protective film. Let’s take a look at how to paste stainless steel film.
Main points of stainless steel production and processing manufacturers using stainless steel protective film
1. Ordinary stainless steel protective film: only used to protect the stainless steel surface
Usually on the most commonly used surfaces, stainless steel frosted surface, stainless steel brushed surface, stainless steel mirror BA surface; usually the frosted brushed surface should be pasted with a stainless steel protective film with a slightly higher viscosity, generally above 70 sticks. The stainless steel mirror panel BA board needs to be pasted with a stainless steel protective film with a lower viscosity, generally below 40, and different viscosity protective films should be pasted according to different materials and the surface finish of the stainless steel plate.
2. Stainless steel protective film (laser film) for laser: usually used for laser cutting of stainless steel plate
In general, the stainless steel plate used for stainless steel laser cutting cannot use ordinary stainless steel film, and needs to use a special stainless steel laser film; while laser cutting processing includes carbon dioxide laser cutting and fiber cutting machine, and the fiber optic machine needs to be protected by fiber optic film. In addition, the current stainless steel laser cutting processing equipment is developing rapidly, and the laser cutting equipment produced by different wattages and different manufacturers will also have certain differences in the filming of stainless steel plates. It is necessary to pay special attention to the thickness and viscosity of the laser equipment film with different wattages, which need to be adjusted according to the processing equipment, and also need to paste different viscosity laser films or optical fiber special films for different stainless steel surfaces.
3. Stainless steel protective film for stretching: the film material needs to be stretched or stamped later
The main feature of the stretch film is that the protective film itself has a certain toughness and is suitable for stretching or stamping. In addition, the appropriate viscosity and thickness of the stainless steel film are also the key points for stretching and stamping parts. If the viscosity is not enough, it is easy for the film to be blown up during the production process, and the purpose of protecting the stainless steel surface is not achieved; however, if the viscosity is too high, the film of the stainless steel product will be difficult to tear off after stretching and stamping, and it takes a lot of manpower to tear the film.
4. Filming methods according to special requirements: single-sided film, double-sided film, double-layer film, spaced film
Due to the needs of subsequent production and processing, stainless steel film can be processed in various ways, such as single-sided film, double-sided film, double-layer film, spaced strip film, etc. The thickness and quality of stainless steel film and film processing operations all affect stainless steel. An important factor in whether the film processing can be carried out as expected and achieve the corresponding effect. Therefore, when making a stainless steel film processing sheet, it is generally necessary to do some film tearing tests or even try stretching, and test laser cutting and other tests during operation. Otherwise, the stainless steel material produced through multiple processes may require a lot of manpower to rework later due to the carelessness of the last step of filming, and it is even possible that the entire batch of stainless steel materials will be scrapped.
