Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Its surface is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. Gold supplier 304 304L stainless steel plate is an alloy steel that is not easy to rust, but it is not rust-free.
Main points of using stainless steel protective film in the production and processing of Gold supplier 304 304L stainless steel plate:
1. Stainless steel protective film for laser (laser film): usually used for laser cutting production of stainless steel plate
Under normal circumstances, the Gold supplier 304 304L stainless steel plate used for stainless steel laser cutting cannot use ordinary stainless steel film, and need to use special stainless steel laser film; while laser cutting processing has carbon dioxide laser cutting and fiber cutting machines, while fiber optic machines require Use optical fiber film for protection. In addition, the current rapid development of stainless steel laser cutting processing equipment, 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 film of different wattage laser equipment need to be adjusted according to the processing equipment, and it is also necessary to apply different viscosity laser film or special fiber film for different stainless steel surfaces.
2. Ordinary stainless steel protective film: only used to protect the surface of stainless steel
Usually on the commonly used surfaces, stainless steel frosted surface, stainless steel brushed surface, stainless steel mirror BA surface; usually frosted brushed surface should be pasted with a stainless steel protective film with a slightly higher viscosity, generally above 70. The stainless steel mirror panel BA board needs to be pasted with a low-viscosity stainless steel protective film.
3. Filming methods in response to special requirements: single-sided filming, double-sided filming, double-layer filming, interval filming
Out of the need for subsequent production and processing, stainless steel film can be processed in a variety of ways such as single-sided film, double-sided film, double-layer film, interval and strip film, etc. The thickness and quality of stainless steel film and film processing operations affect stainless steel. An important factor in whether the film processing can proceed as expected and achieve the corresponding effect.
Therefore, when making stainless steel film processing orders, it is generally necessary to do some tearing tests or even test stretching, and laser cutting tests during operation. Otherwise, the stainless steel materials produced through multiple processes may require a lot of manpower to rework later due to the carelessness of the last step of the film, and it may even cause the entire batch of stainless steel materials to be scrapped.
4. 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 filming for stretching and stamping parts. If the viscosity is not enough, the film is easily blown up during the production process, and the purpose of protecting the surface of the stainless steel is not achieved; but too high viscosity will cause the film of the stainless steel product to be difficult to tear off after stretching and stamping, requiring a lot of manpower to tear the film.
