Study On Peeling Strength Of Edge Banding Of Wood Frameless Honeycomb Panel

As one of the common green materials,wood frameless honeycomb panels have the advantages of light weight,high strength,low cost,and customizable production.However,the application of wood frameless honeycomb panels in furniture production is rare.Among them,the edge sealing process This is one of the main issues that affect its promotion.This paper studies the peel strength of wood frameless honeycomb panels in furniture production,optimizes the peeling detection method,and then uses soft edge banding(PVC as an example)And hard edge banding(aluminum alloy as an example)two categories,respectively,explore the influence of process factors on the peel strength of edge banding,and have a certain positive effect on the optimization of wood frameless honeycomb panels in furniture production.effect.1.The paper firstly analyzes the peel strength test method of edge banding.The peel strength test of soft edge banding is in the relevant industry standard "QB/T 4448-2013 Determination of the peeling strength of soft cladding materials on furniture surface".When the edge strip is bent 180 degrees,the bending strength is greater than the peel strength,which leads to inaccurate test results and the edge band is bent too large and breaks.According to this,a design is designed to ensure that the peeling angle is 90 degrees through two fixed pulleys.Test device for testing.In the relevant industry standard "QB/T 4448-2013 Determination of the Peel Strength of Hard Cladding Materials on Furniture Surfaces",the peeling strength of hard edge banding strips is tested.When the bending strength of the edge banding Based on the problem of the bending strength of the edge strips,a test device was designed to fix the peeling through the upper and lower clamps for testing.2.Aiming at the edge sealing process of the soft edge banding of wooden frameless honeycomb panels,the four process factors of the core layer type of the panel,the thickness of the panel,the type of adhesive,and the thickness of the edge banding are selected for specific research.The expansion experiment of thick honeycomb panel(upper and lower panel 5mm core layer 30mm),the results show:?The average peel strength of the panel with the core layer is 1628N/M,which is about 1.67 times that of the core layer with the second side.The main reason is that the No.1 side core layer can provide a certain bonding strength,and the No.2 side core layer hardly provides bonding strength.?With the increase of plate thickness,the edge sealing peel strength of wooden frameless honeycomb panel shows a decreasing trend.Compared with 25mm thick plate,the average peel strength of 40mm thick plate is 1628N/M,which is a 21%decrease.The main reason is that the peel strength of the surface plate is greater than the peel strength of the core layer.?When using PUR hot-melt adhesive,EVA hot-melt adhesive and polyurethane foam adhesive for edge sealing,the average peel strength of PUR hot-melt adhesive edge sealing is 2762N/M,and the average peel strength of EVA hot-melt adhesive edge sealing is 1629N/M.The average peel strength of styrofoam edge sealing is 773N/M,and the edge sealing process of PUR hot melt adhesive and EVA hot melt adhesive is relatively simple.?As the thickness of PVC edge bands increases,the peel strength of edge bands tends to increase slightly.The average peel strength of 0.8mm thick edge bands is 1629N/M,and the average peel strength of 1.2mm thick edge bands is 1650N/m.When the 2mm thick edge band is peeled off,the bending strength of the edge band has a great influence on the peel strength,and the test result is not entirely the peel strength.After analysis and conclusion,when 1.2mm thick edge banding and PUR hot melt adhesive are used to seal the core layer of 40mm thick plate as the No.1 edge,the peel strength of the plate edge is the highest,and through comparative experiments,the optimal process conditions Below,the peeling strength of wood frameless honeycomb panel is greater than the peeling strength of wood framed honeycomb panel when the traditional edge sealing process is used.3.According to the hard edge banding process of wooden frameless honeycomb panels,four process factors of panel core layer type,panel thickness,adhesive type,and edge band shape are selected for specific research.The 40mm thick honeycomb panel was launched and the results showed that:?The core layer type has no effect on the peeling strength of the hard edge banding strip.?The thickness of the board has little effect on the peeling strength of the hard edge banding.The main reason is that a layer of glue film can be formed at the core layer of the board,which ensures that the bonding strength of the core layer and the surface board is not much different.?When using epoxy resin and white latex to seal the edges,the average peel strength of the epoxy resin edge is 10687N/M,and the average peel strength of the white latex edge is 8075N/M.The curing time of the white latex edge is relatively long..? The average peel strength when using U-shaped edge banding is 10687N/M,and the average peel strength when using several types of edge banding is 10905N/M.The peel strength is not much different,but the edge sealing effect is different.Compared with soft edge banding,the edge banding process of hard edge banding is relatively complicated,but the peeling strength of edge banding is much greater than that of soft edge banding.At the same time,it can also strengthen the plate.Through the above experimental research,the relatively superior edge sealing process of wood frameless honeycomb panel is obtained,which enriches the research on the edge sealing process of wood frameless honeycomb panel,and the application of wood frameless honeycomb panel in the furniture industry Has a certain promoting effect.
