Aluminium-plastic Composite Panel for Curtain Wall Testing

July 3, 2009 - PRLog -- Curtain wall aluminium composite panel refers to the composite panel applied as building curtain wall, which is the composite panel with plastic material as the central layer and aluminium on two sides of it as well as decorative and protective coatings or films as the decorative sides. Now, there are stricter quality requirements for new materials in construction and building decoration. The manufacturers, based on those requirements, bring more standard quality control methods and means.
The peeling strength of curtain wall aluminum-plastic composite panel is of vital importance. The competence of composite strength between the aluminum panel and the plastic layer is the guarantee for future stable and reliable performance. The testing is as follows:
Peel two ends of the aluminum material to be tested, of which, cut the central plastic part and aluminum part of one peeled end. Then, clamp the remaining aluminum on the upper panel and connect with the upper clamp. Clamp the other peeled end on the roller. Keep the length axis in vertical direction with the central axis of the roller, clear zero of the tester load, and connect the lower panel with the lower clamp of the tester; set the testing speed of 25mm/min for tensile until a minimum of 150mm is peeled. Record the peeling strength and curve simultaneously. Though there are detailed regulations of specimen preparation in the standard, the specimen preparation process would affect status of the two ends of the aluminum specimen. Therefore, in order to obtain accurate data and reduce the influence of the preconditioned (pre-peeling) process to the testing results, the tester should have a function of end deletion. Labthink PARAM XLW Auto Tensile Tester specializes in the material peeling strength testing. It is of high precision, equipped with powerful software and the end deletion function, which can better suit the peeling strength testing demand of the aluminum-plastic composite panel.
Besides, PARAM Auto Tensile Tester can perform 180 degree peeling strength, roller peeling strength, tensile strength and elongation rate testing of protective film and laminated adhesive film (high polymer film) of aluminum-plastic composite panel.
