The refrigerator glue, as a key sealing accessory between the refrigerator door and the cabinet, plays a crucial role. It consists of two parts: a soft PVC (SPVC) jacket and a magnetic strip. Through precise processing and extrusion techniques, it ensures the door's seal, preventing cold air from leaking. To meet the needs of different refrigerator models and designs in the market, the shape and structure of the glue for refrigerators vary. The magnetic strip tightly attaches the door gasket to the cabinet through its adsorption force, forming an effective sealing barrier that prevents external hot air from entering the refrigerator and reduces cold air loss.
The importance of the refrigerator glue in everyday use cannot be ignored. It not only helps maintain the internal temperature of the refrigerator but also extends the freshness period of food. When the refrigerator door is closed, the refrigerator glue tightly fits the door frame, forming an effective barrier to prevent cold air from leaking. This allows the refrigerator to operate more efficiently, saving energy consumption, and enhancing the freshness effect. Particularly for food that needs long-term storage, a well-maintained refrigerator glue can significantly extend the freshness period, preventing food from spoiling due to temperature fluctuations.
For example, if the glue for refrigerators is aged or damaged, cold air will continue to leak from the refrigerator, causing the temperature to rise and drastically shortening the freshness period of food. Perishable items like fresh vegetables and fruits are especially susceptible to spoilage due to temperature instability.
Despite the critical role of the refrigerator glue, it may fall off or lose its sealing effect during long-term use. Common reasons include:
Frequent opening and closing of the door over a long period cause the refrigerator glue to be under constant stress, leading to gradual aging or deformation. An aged refrigerator glue loses its original elasticity and sealing capacity, possibly resulting in loose sealing or even falling off.
The suction of the refrigerator glue is key to maintaining the door's sealing effect. If not designed properly, or if the refrigerator door becomes loose after long-term use, the refrigerator glue's suction may weaken, failing to effectively adhere to the cabinet and resulting in poor sealing or falling off.
During use, the refrigerator glue may be subjected to external pressure, collisions, or other physical damage, causing it to be displaced or deformed, which ultimately affects the sealing effect or causes it to fall off.
If the refrigerator glue is not cleaned for an extended period, accumulated dirt may reduce its adhesiveness, preventing the door from closing tightly and even causing the refrigerator glue to fall off due to accumulated grime.
When replacing the refrigerator glue, improper installation or insufficient cleaning may prevent the new refrigerator glue from fully adhering, leading to poor sealing or falling off.
When the glue falls off or has poor sealing, timely emergency repair or replacement with a new refrigerator glue is an effective solution.
If no spare parts are available for replacement, simple repair methods can delay the problem. First, detach the refrigerator door, cut open the adhesive at the four corners of the refrigerator glue, remove the plastic magnetic strip, and attach it to the cabinet. Next, soak the refrigerator glue in hot water at 55-65°C for 4-6 minutes, then take it out and adjust its shape, ensuring it is flat without any uneven areas. Finally, reattach the magnetic strip and glue the four corners with 502 glue, ensuring the suction surface of the magnetic strip faces the cabinet.
If the refrigerator glue is severely damaged or aged, replacing it with a new refrigerator glue is the most effective solution. First, remove the old refrigerator glue and clean the debris in the installation groove. Then install the new refrigerator glue into the designated groove, ensuring it is flat and does not rub against the refrigerator surface. When installing the new refrigerator glue, keep the interior of the refrigerator clean to avoid contaminants affecting the sealing effect. After replacement, check the refrigerator glue's sealing performance to ensure the door can be tightly closed.
