Factors of Peel Strength of Aluminum Honeycomb Panels

　　(1)Factors of Peel Strength of Aluminum Honeycomb PanelsThe aluminum honeycomb panel produced by polyurethane and epoxy resin room temperature curing adhesive has low bonding strength. The 180 peel strength measured for aluminum honeycomb panel with honeycomb core side length of 4mm, panel thickness of 1mm and total thickness of 10mm is about 4N/mm. The adhesion and weather resistance of this aluminum honeycomb panel are poor, and the adhesion performance is greatly reduced after 1 year of use. Produced by this processaluminum honeycomb panelNot suitable for outdoor, but can be used for indoor decoration partition.

Factors of Peel Strength of Aluminum Honeycomb Panel The bonding strength of aluminum honeycomb panel produced by epoxy film process is low. For aluminum honeycomb panel with honeycomb core side length of 4mm, panel thickness of 1mm and total thickness of 10mm, the measured 180 peel strength is about 4N/mm, however, its bonding

Factors of peel strength of aluminum honeycomb panel,heterosexual double curved plateThe performance is good weather resistance, and the peel strength decreases very little after 1 year of use. The disadvantage is that the bonding layer of the aluminum honeycomb panel is brittle, and the aluminum honeycomb panel will be layered after long-term vibration.

Aluminum honeycomb panel peel strength factors using hot press production of aluminum honeycomb panel, due to the hot press pressure, more difficult to control, in order to prevent collapse of aluminum honeycomb core, often placed pad. If the pad is high, it will affect the applied pressure, resulting in low bonding strength. Such as the use of flat thermal composite machine, because the pressure is provided by the elastic force, can be adjusted by the height to control the applied pressure, therefore, the use of this process of production of aluminum honeycomb panel bonding strength is high, and very stable.

The oil, dirt and naturally formed loose oxide layer on the aluminum surface will seriously affect the bonding effect of the aluminum honeycomb panel. Therefore, it must be cleaned and pretreated. Aluminum surface can be phosphated or chromized, aluminum honeycomb plate peel strength factors make the aluminum surface to form a layer of close chemical conversion film, after treatment of aluminum bonding effect is good.
