Happy to bring a new refrigerator home and prepare to transfer the refrigerator sticker from the old one. It was found that the smooth mirror like door panel of the new refrigerator couldn't hold the refrigerator sticker. This may be the awkward situation that many refrigerator sticker enthusiasts encounter after changing their refrigerators nowadays. Many netizens roast on social media that the refrigerator has more functions, but the refrigerator door has "degenerated". So, why can't the refrigerator door hold the refrigerator sticker now? The reporter from Science and Technology Daily interviewed relevant experts on this matter. The panel is undergoing updates and upgrades. In the past, the refrigerator door could hold the refrigerator sticker, mainly because its panel is made of metal material. But now, glass panels are replacing metal panels as the new "facade" of refrigerator doors. Zhang Yanbin, a senior analyst in the household appliance industry, pointed out that in history, refrigerator panels were mostly made of steel plates. However, with the advancement of material technology and the improvement of consumer aesthetic standards, the material of refrigerator panels continues to be upgraded. At present, most of China's major household appliance brands have used glass panels to make refrigerator doors. This transformation is not only a result of technological innovation, but also a response to changes in consumer demand. The marketing manager of a refrigerator brand in a household appliance store in Beijing said that in the past, consumers valued the durability of refrigerators, so the metal panels used to make refrigerator doors in the early days were usually made of corrosion-resistant materials such as stainless steel or galvanized sheet. With the improvement of people's living standards, consumers have increasingly high expectations for refrigerators, which has driven the upgrading of production technology and processes. Glass panels have the characteristics of transparency and brightness, which can enhance the aesthetics and design sense of refrigerators, and are gradually favored by consumers. In addition to its outstanding appearance, glass panels also have significant advantages in practicality. Specially treated glass panels have high strength and hardness, are not easily scratched or discolored, and have good resistance to dirt, making them easy to clean. It is worth mentioning that some high-end brand refrigerators currently use more innovative rock panels. This new type of panel is similar in texture to rocks and ceramics, with a unique touch and higher hardness than glass panels, providing consumers with a unique user experience. The continuous upgrading of functional design and changes in refrigerator panel materials are just a microcosm of the recent upgrades in refrigerator functionality and design. Nowadays, refrigerators are no longer just tools for preserving food. At present, large capacity refrigerators available on the market usually have four large independent compartments, with the upper compartment being a double open refrigeration compartment and the lower compartment being a double open freezing compartment. In addition to traditional refrigeration and freezing areas, a variable temperature zone that can freely adjust temperature between 5 degrees Celsius and 20 degrees Celsius has been added, as well as other spaces with special preservation functions. The temperature of each partition can be independently set and adjusted as needed. To a large extent, this solves the problem of food mixing together in traditional refrigerators. The refrigerator door opening design not only makes food retrieval more convenient, but also reduces energy consumption and saves electricity costs. In addition to finely distinguishing storage space, the designers also upgraded the freezing speed of the refrigerator. Traditional refrigerators occasionally experience issues such as incomplete freezing and uneven freezing when freezing food. Due to uneven freezing in the refrigerator, the ingredients placed at the bottom may have completely frozen, while the ingredients on the top may not have been frozen yet. To address these issues, some refrigerator brands have introduced instant freezing technology. It can quickly lower the temperature inside the refrigerator to minus 40 degrees Celsius at an ambient temperature of 20 degrees Celsius, allowing ingredients to freeze quickly and lock in their "original flavor" to the greatest extent possible, satisfying people's pursuit of fresh and tender taste. Where does the refrigerator sticker go? With the upgrade of the refrigerator door panel, can refrigerator stickers only be retired? That's not true either. A netizen shared on social media that they can purchase "magnet magnets" online and use them to attract refrigerator magnets. Magnetic tile "is actually a metal sheet with a layer of adhesive on the back. Consumers can stick it on the refrigerator door and then attach the refrigerator to it. If you don't want to spend money on renovation, you can have the refrigerator labeled "transfer position" - on the side of the refrigerator. Generally speaking, the side of a refrigerator does not have high aesthetic requirements, and considering heat dissipation, it is mainly made of low-cost and durable metal materials. Therefore, the side of the refrigerator can hold the refrigerator sticker. (New Society)
