Factors Affecting the Peel Strength of Aluminum Honeycomb Panels

　　aluminum honeycomb panel是一种较为常见的复合材料，尤其是一些大厦的外墙装饰材料，由于其独特的优点被许多消费者所喜爱，具有一般复合材料所没有的优点，但是，如果加工处理不好，aluminum honeycomb panelThere are many factors that cause peeling. What factors affect the peeling strength?

Adhesive for 1. aluminum honeycomb panel

Selection of polypropylene materials, epoxy resin glue room temperature curing adhesive production Products, the bonding compressive strength is low, the bonding performance of such Products is weak, aging resistance is poor, the use of a year after the bonding performance decreased significantly. The Products produced by this process are not suitable for outdoor use, but can be used for interior decoration design as a baffle.

The product produced by epoxy resin film processing technology has low bonding strength and good aging resistance, and the strength decreases little after one year. The disadvantage is that the bonding layer is brittle and delamination is formed after vibration.

The adhesive strength of the Products produced by the continuous composite processing process of thermosetting plastic adhesive paper is 3-5 times higher than that of the Products produced by the first two processes. Its adhesive performance and aging resistance are good, and the strength decreases little after one year. Due to the continuous production and high efficiency, a large number of deliveries in a short period of time can be considered. The disadvantage of this processing technology is that the selected plane continuous heat sealing machine is expensive and the engineering investment is large. Thermosetting plastic adhesive paper is this unique hot melt adhesive film. The adhesive paper itself must have high cohesive compressive strength and tensile strength, so as to ensure that the aluminum plate is firmly bonded.

Production Process of 2. Aluminum Honeycomb Panel

Due to the high working pressure of the hot press and the difficulty of operation, in order to avoid the collapse of the aluminum core material, a protective layer pad is often placed, so the Products produced by the hot press are selected. Assuming that the protective layer pad is high, it will affect the release of the working pressure, resulting in low bond strength. For example, the matching plan hot press, because the working pressure is elastic, can adjust the height to width ratio of the release of the working pressure, so the selection of this processing technology to produce Products with high bond strength, and very stable.

3. aluminum honeycomb panel surface material

The oil stains, stains and naturally occurring bubble oxide layer of metal sheet have a great influence on the actual bonding effect of aluminum sheet. Therefore, it must be cleaned and normalized. Pickling phosphating or chromizing method can be selected to solve the problem, so that the aluminum plate forms a layer of inseparable organic chemical conversion film, and the aluminum plate after the solution has good bonding performance.
