Abstract
Description
Technical Field
[0001] This application relates to the field of glove manufacturing technology, and in particular to a corrosion-resistant and wear-resistant stainless steel hand mold. Background Technology
[0002] The production of nitrile gloves requires the use of molds and an immersion molding process. The manufacturing process begins with acid washing, alkali washing, rinsing, and drying of the mold. Then, the mold is immersed in a coagulant solution and latex liquefaction materials. Next, the nitrile film layer impregnated on the mold is baked and chlorinated, and finally, the product is demolded. Therefore, the molds used to produce nitrile gloves need to be resistant to acids, alkalis, and chloride ion corrosion, while also possessing thermal conductivity, thermal shock resistance, good wetting properties, and good demolding ability.
[0003] In the existing technology, the PVC nitrile product industry uses ceramic molds extensively for product production. The characteristics of ceramic molds are thick walls, poor thermal conductivity, and slow heating and cooling. These characteristics are important factors contributing to the high energy consumption in this industry, which in turn leads to high production costs and low glove production efficiency, and these issues need to be improved. Summary of the Invention
[0004] In view of this, the purpose of this application is to provide a corrosion-resistant and wear-resistant stainless steel hand mold to reduce costs and improve production efficiency. The specific solution is as follows:
[0005] A corrosion-resistant and wear-resistant stainless steel hand mold includes a stainless steel body in the shape of a palm; a stainless steel main body is provided on the inner side of the stainless steel body, and an electroplated protective layer and a hydrophilic surface layer are provided on the outer side of the stainless steel main body; the electroplated protective layer is a chloride ion corrosion resistant layer; the hydrophilic surface layer is a textured layer.
[0006] Preferably, the chloride ion corrosion resistant layer is a hard chrome protective layer.
[0007] Preferably, a coarse hemp layer is provided between the stainless steel body and the electroplated protective layer; the overall thickness of the coarse hemp layer, the electroplated protective layer and the hydrophilic surface layer is 0.02-0.06 mm.
[0008] Preferably, the hemp layer is a fine hemp layer; the surface area of the coarse hemp layer is 3-4 times that of the fine hemp layer.
[0009] Preferably, the stainless steel body is a 316L stainless steel blank.
[0010] As can be seen from the above solutions, this application provides a corrosion-resistant and wear-resistant stainless steel hand mold. The corrosion-resistant and wear-resistant stainless steel hand mold significantly improves wear resistance and corrosion resistance through a multi-layer composite structure. By replacing existing ceramic materials with stainless steel, it significantly improves thermal conductivity and corrosion resistance while achieving high strength, wear resistance and vibration resistance, and effectively reduces energy consumption, thereby significantly improving the production efficiency of gloves.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0016] like Figure 1 As shown, a corrosion-resistant and wear-resistant stainless steel hand mold includes a stainless steel body 1 shaped like a palm. Given that stainless steel has excellent thermal conductivity and corrosion resistance, while also providing high rigidity, shock resistance, and wear resistance, the stainless steel body 1 achieves energy savings of 30-40% compared to ceramic molds. Furthermore, the stainless steel body 1 is easily recyclable, thus reducing environmental pollution and resource waste.
[0017] like Figure 2As shown, a stainless steel body 11 is provided on the inner side of the stainless steel body 1. Simultaneously, an electroplated protective layer 3 and a hydrophilic surface layer are provided on the outer side of the stainless steel body 11. The electroplated protective layer 3 is an anti-chloride ion corrosion layer, effectively resisting chloride ion corrosion and extending service life. The hydrophilic surface layer is a textured layer. Therefore, the textured layer provides good wettability for the corrosion-resistant and wear-resistant stainless steel hand mold, thereby achieving uniform wetting of the coagulant, demolding machine, impregnation, and facilitating demolding.
[0018] It should be mentioned that the chloride ion corrosion resistant layer in this embodiment is a hard chrome protective layer. The hard chrome protective layer effectively separates the corrosive medium from the stainless steel body 11, thereby improving corrosion resistance. Furthermore, the chloride ion corrosion resistant layer obtained by electroplating is free of voids and cracks, promoting grain refinement and improving adhesion. Simultaneously, a coarse hemp layer 2 is provided between the stainless steel body 11 and the electroplated protective layer 3. The coarse hemp layer 2 significantly improves the adhesion between the chloride ion corrosion resistant layer and the stainless steel body 11, and enhances wear resistance.
[0019] To achieve effective corrosion resistance and wear resistance, the overall thickness of the coarse hemp layer 2, the electroplated protective layer 3, and the hydrophilic surface layer in this embodiment is 0.02-0.06 mm.
[0020] It should be noted that in this embodiment, the textured layer is a fine textured layer 4, and the surface area of the coarse textured layer 2 is 3-4 times that of the fine textured layer 4. The stainless steel body 11 is a 316L stainless steel blank.
[0021] In summary, this application provides a corrosion-resistant and wear-resistant stainless steel hand mold. This corrosion-resistant and wear-resistant stainless steel hand mold significantly improves wear resistance and corrosion resistance through a multi-layer composite structure. By replacing existing ceramic materials with stainless steel, it significantly improves thermal conductivity and corrosion resistance while achieving high strength, wear resistance and vibration resistance, and effectively reduces energy consumption, thereby significantly improving the production efficiency of gloves.
