Effect of sealing strip design and material on the sealing performance of upright stainless steel refrigerator door

By admin / Date Nov 12,2024

In the context of the continuous development of modern refrigeration technology, upright stainless steel refrigerators have become a popular choice for homes and commercial places due to their excellent durability, elegant appearance and efficient refrigeration performance. However, the overall performance of a refrigerator is not limited to its refrigeration system and internal structure design. The sealing performance of the door body is also crucial. In this regard, the design and material of the sealing strip have become the core factors affecting the sealing performance of the door body.

The impact of the design of the sealing strip on the sealing performance of the door body cannot be ignored. The structure of the sealing strip is directly related to whether an effective sealing space can be formed between the door body and the cabinet. In upright stainless steel refrigerators, the sealing strip is usually made of elastic material that fits tightly to the edge of the door body. This design not only requires the sealing strip to have sufficient elasticity so that it can automatically adjust its shape when the door body is closed to ensure close contact with the cabinet surface, but also has good wear resistance and aging resistance to ensure the sealing effect in long-term use.

The key to achieving an ideal sealing effect lies in the comprehensive consideration of the design of the sealing strip. First of all, the cross-sectional shape of the sealing strip is an important factor, which determines the area and method of contact between the sealing strip and the door body and the cabinet. By optimizing the cross-sectional shape, the friction between the sealing strip and the contact surface can be effectively increased, thereby improving the sealing effect. Secondly, the compression of the sealing strip, that is, the degree of compression of the sealing strip when the door is closed, is also crucial. Appropriate compression can ensure that the sealing strip fits tightly between the door and the cabinet to form an effective sealing barrier. In addition, the installation position and method of the sealing strip also affect the sealing effect. Reasonable installation position and method can ensure that the sealing strip is evenly stressed when the door is closed, avoiding sealing failure caused by excessive or insufficient local pressure.

The material of the sealing strip also has a significant impact on the sealing performance of the door. The physical and chemical properties of different materials directly determine the performance of the sealing strip during use. In vertical stainless steel refrigerators, common sealing strip materials include silicone, rubber and plastic. Silicone material can maintain a stable sealing effect in extreme environments due to its excellent high temperature resistance, low temperature resistance, oxidation resistance and chemical corrosion resistance. The elasticity and wear resistance of silicone enable it to maintain good shape stability during long-term use. In contrast, although rubber material has good elasticity and sealing performance, it is relatively inferior in high temperature resistance and chemical corrosion resistance. The advantages of plastic materials are low cost and easy processing, but their resistance to high temperature, aging and wear is relatively weak.

When choosing the material of the sealing strip, factors such as the use environment of the refrigerator, the requirements of the refrigeration system and the cost should be considered comprehensively. For refrigerators that need to operate for a long time in extreme environments, such as upright stainless steel refrigerators in commercial kitchens, silicone material is a more ideal choice. In some occasions with higher requirements on cost, you can consider using rubber or plastic materials with slightly inferior performance, but additional measures need to be taken during the design and use process to ensure the reliability of the sealing effect.
