304L stainless steel is the material, which is a low-carbon austenitic stainless steel. Its overall performance is similar to that of 304 stainless steel, especially its ability to resist intergranular corrosion is stronger.
"Mirror surface" refers to the surface state of 304L stainless steel, which is called 8K surface in the stainless steel industry. Common mirror stainless steels on the market are divided into four mirror grades: 6K, 8K, 10K, and 12K.
With the improvement of the decoration grade in the architectural decoration market, the scope of mirror stainless steel decoration is getting wider and wider. However, there are various processing and installation methods for mirror stainless steel, and special attention should be paid to the construction site.
1. Pretreatment before bending
304L stainless steel mirror panels often have inconsistent reflectivity due to the wavy surface, which affects the appearance. There are many reasons for this phenomenon. One of the reasons is that many people think that the 304L stainless steel mirror panel is too thin, but it is not, because there is no pretreatment before bending.
Bending processing refers to the tensile deformation of the 304L stainless steel mirror panel at the rigid and non-plastic bending position. At present, any high-precision bending equipment on the market cannot 100% guarantee that the stress of the bent plate is concentrated at the sharp point of the knife edge, which makes the bending deformation of the bent plate product near the bending extension line inconsistent, resulting in waves on the surface of the 304L stainless steel mirror panel. ups and downs.
2. Knife edge treatment at seams
In addition to the general requirements for the elevation, axial position, verticality, and levelness of doors and windows, the construction particularity of 304L stainless steel mirror panel doors and windows mainly lies in the construction of joints, which is a problem that Party A usually cares about when checking and accepting, so 304L The quality index requirements for stainless steel mirror panel seams are as follows:
(1) Be consistent: the gap should be consistent on its extension line;
(2) Sealing: the gap must be less than 0.5mm, invisible to the naked eye;
(3) Flatness: at the joints, ensure that the board surface at the corner is flat, and there is no phenomenon of going in and out. It is not allowed to use hard tools to beat the board surface to cause deformation. Pay attention to the gap between the horizontal material and the vertical material of mirror stainless steel doors and windows. difference between.
3. Use glass glue to seal
Glass glue is often used to seal mirror stainless steel doors and windows with glass or with the environment. Cooperate with workers to achieve a smooth, wave-free and shiny installation effect. Pay attention to the following points:
(1) Choose the size of the outlet of the glass nozzle according to the shape of the material installation, and use a sharp blade to cut it into a 60° cut;
(2) When gluing, pay attention to keep the glue gun and the glass at an angle of about 60°;
(3) Use uniform force to make the glass glue squeeze out slowly, while keeping the glass glue nozzle moving forward at a uniform speed.
The 304L stainless steel mirror panel installed in the above way has a clean and flat surface, beautiful joints, and smooth and shiny glass glue, thereby improving the quality of decoration.
