Aluminum honeycomb panel is a relatively common composite material, especially for the exterior wall decoration of some buildings. Because of its unique advantages, it has been sought after by many consumers. It has advantages that ordinary composite materials do not have. However, if If the processing is not good, it will cause the peeling phenomenon. There are many factors that cause this phenomenon. What are the factors that affect the peel strength?
1. Products manufactured by using polyurethane materials and epoxy resin indoor temperature curing adhesives have low bonding compressive strength. The adhesion and aging resistance of these products are weak, and the bonding characteristics are large after one year of application. Decreased. Products manufactured using this type of processing technology are not suitable for outdoor use, but can be used as decorative design baffles in rooms.
2. The epoxy resin film processing technology is used to produce products with low bonding strength, good aging resistance, and its strength does not decrease after one year of application. The disadvantage is that the adhesive layer is relatively brittle and will produce layers after vibration.
3. The bonding strength of the products manufactured by using the thermosetting plastic adhesive tape continuous composite processing technology is 3-5 times that of the first two processing technologies. Its adhesion and aging resistance are good. After one year of application, its strength will not decrease Big. Because it is continuous production and high efficiency, a large number of delivery regulations in the short term can be considered. The drawback of this type of processing technology is that the floor plan used in the continuous heating machine is expensive and the project investment is huge. Thermosetting plastic adhesive tape is this unique hot melt adhesive film. The adhesive tape itself must have high cohesive compressive strength and tensile strength, so as to ensure the strong adhesion of the aluminum honeycomb panel.
