The glue coating process has gained significant recognition in recent years, especially with the growing popularity of German Vitu Cabinets in China. This innovative technique involves a two-component polyurethane reactive process, but many users still harbor misconceptions about its requirements and best practices. This article aims to clarify these misunderstandings and provide insights for those adopting this technology.
One common misconception about the glue coating process is that it functions similarly to single-sided adhesive foam strips. Some fear that such strips will eventually peel off due to lack of adhesion. These foam strips are typically bonded using a physical method, relying solely on the adhesive's viscosity. However, this type of bonding is sensitive to environmental changes. For instance, colder temperatures weaken the adhesive strength, while heat reduces it further. Over time, this leads to detachment. Conversely, glue strips produced via the glue coating process undergo a chemical reaction between two components, creating a permanent bond. This chemical bonding ensures durability regardless of weather conditions or prolonged usage, making it far superior to physical bonding methods.
Dalian Huagong Innovation Technology Co., Ltd., an early adopter of glue coating technology in China, has been at the forefront of this field. Mr. Han, a key figure in the company, emphasizes pre- and post-sale support, ensuring clients experience top-notch service. Their equipment is now exported globally, and they continue to innovate. We invite interested parties to reach out for collaboration.
Another misunderstanding revolves around the belief that the glue coating process applies universally without considering material compatibility. Materials with high surface tension tend to bond better with the glue, resulting in stronger adhesion. In contrast, materials with lower tension may not bond well, leading to potential detachment. To address this issue, primers can be applied to enhance adhesion, particularly on stainless steel surfaces. Alternatively, flame activation can be used for plastics and coated surfaces.
A third misconception involves ignoring environmental factors during the glue coating process. High temperatures accelerate the reaction, potentially causing thicker glue strips with larger bubbles, reducing adhesion and smoothness. Low temperatures might prevent proper curing, leaving the strips rigid and less flexible. Similarly, low humidity could harden the strips. These issues highlight the importance of maintaining optimal environmental conditions and ensuring high-quality machinery.
Finally, there’s a misconception suggesting that the quality of glue strips depends solely on equipment rather than the glue itself. While equipment plays a crucial role, the choice of glue is equally vital. High-quality glue ensures consistent performance, ease of application, and long-lasting strips. Such glue maintains elasticity over time, minimizes waste, and requires fewer cleanings. Therefore, selecting reliable glue with stable properties is essential for achieving optimal results.
In conclusion, the glue coating process offers numerous advantages over traditional methods. By addressing these common misunderstandings and adhering to best practices, users can maximize the benefits of this advanced technology.
