[0002] As a lightweight, high-strength, corrosion-resistant material, magnesium alloy has been widely used in aerospace, automobile manufacturing and other fields. Its unique physical and chemical properties give magnesium alloy significant advantages in these fields. However, despite the many advantages of magnesium alloy, there are still some technical challenges in its application in the formwork field.

[0003] In the field of templates, the surface of magnesium alloy templates needs to be specially treated to enhance their wear resistance and corrosion resistance. This is because during use, the template surface is often affected by wear and corrosion, which affects its service life and performance.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0026] Specifically, Figure 1 As shown, a magnesium alloy template is provided in an embodiment of the present application, and the magnesium alloy template includes a template body 100 and a stainless steel plate 200. The template body 100 and the stainless steel plate 200 are connected by providing a connecting agent 300, so that the stainless steel plate 200 is pasted on its template body 100. For the convenience of pasting, a bonding surface 110 is provided on the template body 100 corresponding to a side position of the stainless steel plate 200. The shape of the bonding surface 110 corresponds to the side shape corresponding to the template body 100, and corresponds to the shape of the stainless steel plate 200. In the embodiment of the present application, the thickness of the stainless steel plate 200 is 0.2mm-0.3mm, and the coating thickness of the connecting agent 300 is 0.2mm-0.3mm.

[0027] When the stainless steel plate 200 is connected to the template body 100, the surface of the magnesium alloy template can be prevented from being worn and corroded. During the connection process, the bonding surface 110 on the template body 100 in the magnesium alloy template that needs to be bonded is cleaned. The specific cleaning process is to clean the surface of the template body 100 with a polishing agent. The polishing process uses a hard wax polishing method to polish the surface on the template body 100. The hard wax does not contain acid and alkali components and does not react with the magnesium alloy. It can maintain the strength of the template body 100 in the magnesium alloy template and can make the bonding surface 110 of the magnesium alloy template polished and smooth. During the polishing process, it is necessary to detect its surface roughness. In the embodiment of the present application, the surface roughness of the magnesium alloy is calculated by the surface roughness formula, that is, the RMS formula:

[0028]

[0029] Where: h_i represents the i-th height value of the object surface, h_avg represents the average of all height values, and N is the total number of height values.

[0030] The surface roughness can also be detected by a surface roughness tester. In the present application, the roughness can be detected by a Surtronic S-100 series surface roughness tester.

[0031] The template body 100 is polished and after polishing, the roughness RMS of the bonding surface 110 reaches less than or equal to 1.97 nm, and the surface finish is greater than 10.

[0032] After the magnesium alloy template is physically polished, a bonding surface 110 is formed at the polishing position of the template body 100, and a layer of connecting agent 300 is evenly applied on the bonding surface 110. In the embodiment of the present application, the connecting agent 300 is a glue, specifically a polyurethane potting glue. In the present application, the glue can also be set to epoxy resin glue, two-component epoxy iron glue or acrylic glue.

[0033] When applying glue on the magnesium alloy template, the thickness of the glue on the bonding surface 110 is controlled to be 0.2 mm-0.3 mm. After the thickness is controlled, the stainless steel plate 200 is bonded to the template body 100 by the glue.

[0034] In the embodiment of the present application, the thickness of the stainless steel plate 200 is 0.2mm-0.3mm, and the material of the stainless steel plate 200 is 201 stainless steel. Since the surface of 201 stainless steel is smoother than other types of stainless steel, it is easier to paste on the template body 100, and it is not easy to produce bubbles or gaps. The strength of 201 stainless steel can provide good support for the template body 100.

[0035] When the stainless steel is pasted on the template body 100, the glue needs to be cured to strengthen its connectivity. In the embodiment of the present application, the curing time of the glue is set to 16 hours and the curing temperature is set to 80°C. The curing process can keep the glue layer free of hollows and gaps.

[0036] In the present application, the curing time of the glue can also be set to 14 hours, 18 hours, 20 hours or 24 hours, and the curing temperature can be set to 90°C, 75°C, 70°C or 65°C accordingly.

[0037] To facilitate pasting the stainless steel plate 200 on the template body 100, in an embodiment of the present application, a reinforcing rib 120 is arranged on one side of the template body 100 relative to the pasting surface, and the reinforcing rib 120 includes a first oblique rib 121 and a second oblique rib 122. The cross-arrangement of the first oblique rib 121 and the second oblique rib 122 can strengthen the overall strength of the template body 100, so that the stainless steel plate 200 can be pasted on the template body 100.

[0038] A corrugated structure 130 is also provided on the template body 100 . The corrugated structure 130 is centrally arranged on the template body 100 and is located on one side of the template body 100 relative to the stainless steel plate 200 .

[0039] In the embodiment of the present application, the corrugated structure 130 includes a cross beam 131 and a longitudinal beam 132. The cross beam 131 and the longitudinal beam 132 enclose a fixed groove 133, and a corrugated structure 130 is formed at the bottom of the fixed groove 133. The corrugated structure 130 can reduce the mass of the template body 100, and at the same time, it can play a buffering role on the one hand, and can enhance the overall strength of the template body 100 on the other hand.

[0040] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
