The glue coating process is a relatively new technique that has gained significant recognition in recent years, especially following the growing popularity of German Vitu Cabinets in China. Despite its increasing adoption, many businesses and individuals utilizing this process still harbor misconceptions about its requirements and nuances. This article aims to address these common misunderstandings, offering clarity for those employing this technology.
One prevalent misconception about the glue coating process is that it functions similarly to single-sided adhesive foam strips, which are prone to falling off over time. These foam strips rely on physical bonding, where the glue remains unreacted and adheres solely through its viscosity. This type of bonding is highly sensitive to environmental changes—when temperatures drop, the adhesive's grip weakens, and when they rise, the bond loosens further. Over time, this leads to the inevitable detachment of the foam strip. Conversely, the glue strips produced through the glue coating process undergo a two-component chemical reaction, resulting in an irreversible bond. This chemical bonding is unaffected by environmental fluctuations, ensuring the durability and reliability of the adhesive strip regardless of external conditions.
Dalian Huagong Innovation Technology Co., Ltd., one of the early domestic adopters of this technology, has extensive experience in glue coating processes. As noted by Mr. Han, the company's founder, providing excellent pre- and post-sale support is a priority. Ensuring customer satisfaction while maintaining high product quality is central to their mission. Currently, the company’s equipment has been exported globally, and they continue to innovate and expand their offerings. We warmly invite interested parties to reach out for discussions.
Another misunderstanding revolves around the idea that the glue coating process is universally applicable to all types of materials. The effectiveness of the adhesive depends significantly on the material being bonded. Materials with higher surface tension tend to bond more effectively, creating a stronger adhesive strip. However, if the material or its surface coating has lower surface tension, the bond strength diminishes, potentially leading to detachment. To address this issue, two common solutions are employed: applying a primer before bonding (often used on stainless steel) or using flame activation techniques (suitable for plastics and certain coated surfaces).
A third misunderstanding concerns the impact of environmental factors on the glue coating process. Since this is a chemical reaction-based process, environmental conditions play a crucial role. Higher temperatures accelerate the reaction, potentially leading to thicker adhesive strips with larger internal bubbles. This can affect the strip's adhesion, surface finish, and flexibility, particularly with domestically sourced glues. Lower temperatures might slow down or even halt the reaction, resulting in hardened or less flexible strips. Similarly, low humidity could contribute to brittleness. It is essential to ensure that the machinery is functioning optimally to avoid such issues.
Finally, there is a misunderstanding regarding the quality of the adhesive strips, with some believing that the equipment alone determines their quality. While the equipment is critical, the choice of adhesive is equally important. High-quality glue ensures easier handling, consistent application, and superior strip characteristics. Such glue strips remain elastic over time, exhibit a smooth and reflective surface, and require fewer maintenance cycles, minimizing material wastage. Therefore, selecting reliable, high-performance glue is vital for achieving optimal results.
In summary, the glue coating process offers numerous advantages over traditional methods, but understanding its intricacies is essential for successful implementation. By dispelling these common misconceptions, users can better appreciate the process's potential and achieve consistent, durable results.
