Furniture Edge hot melt adhesive (Edge banding Hot-Melt Adhesive) is a class dedicated to artificial board Edge Adhesives, as a solvent-free thermoplastic rubber. When the hot melt adhesive is heated to a certain temperature, it will from the solid state to a molten state. When applied to the surface of wood-based panels plate or Edge cooled into a solid edge banding material plates bonded together. Edge glue general of the office furniture will be adopted EVA-based hot melt adhesive, Furniture Edge generally require the use of hot melt adhesive to need to meet the following characteristics: 1. Faster cure speed; 2 good heat resistance; 3. Thermal stability good performance; 4 can not be brushed; edge banding and wood have good adhesion.
Edge banding Hot-Melt Adhesive EVA problems and solutions
1.Temperature Effect
Edge hot melt adhesive is mainly affected by temperature, so the edge-sealing process, the temperature is a great need for indicators of concern. when you are banding, hot melt adhesive temperature, the temperature of the plate (a variety of wood-based panels), edge banding material (various PVC tape, veneer and fire board, etc.) and the temperature of the temperature and the working environment (edge banding machine where the plant workshop), all is a very important parameter.
(1) Ineffective adhesion
<1>Problems that may occur：1.1 Hot melt adhesive just stop at the Edge surface
1.2 The surface of the substrate has been processed
1.3 A glue roller occur charring, smoke
1.4 Glue roller and furniture plate contact surface effect is not obvious
1.5 Plate temperature anomalies
1.6 Hot melt adhesive and furniture plate incompatible
<2> Corresponding solutions：2.1 Curing too fast, increase the temperature of the glue appropriately, or increase the amount of glue
2.2 Improve the processing temperature
2.3 Reduce the temperature of the use of edge banding machine, proofing machine temperature regularly
2.4 An appropriate increase in the temperature of the use of edge banding machine, proofing machine temperature regularly
2.5 Plate temperature recommended constant above 20 ℃
2.6 Replace another hot melt adhesive
<3>Suggestion: Edge banding machine working environment temperature will affect the curing speed of the rubber. The reason is that factories often in the low temperature of the season will appear Edge: In winter, hot melt adhesive curing speed becomes faster, the shorter the effective time of the adhesive. If feed edge banding machine speed can not be changed (in most cases), then they would have to ensure that the edge banding quality must preheat plate and edge banding material. While selection of a wide adaptability temperature hot melt adhesive, to do more with less.
2.Edge banding machine type of furniture edge
Edge banding machine feed speed is very important for the selection and use of hot melt adhesive. The fast feed edge banding machine must select open time (time start from glue to glue the effective viscosity) short hot melt adhesive, otherwise, the election open long hours of hot melt adhesive.
(1) The Plate Edge incomplete or excessive Epoxy
<1>Problems that may occur：1.1 Edge banding machine feed speed too fast / too slow
1.2 Hot Melt Adhesive open time is too short
1.3 Glue roller poor contact
1.4 The slow speed of the hot melt adhesive closed
1.5 Operating temperature does not comply
1.6 Edge banding machine nozzle clogging
1.7 Sheet specifications conflict
1.8 Edge irregular
<2> Corresponding solutions：2.1 Checking the speed of the edge banding machine, and appropriately adjusting the feed material rate
2.2 Increase the opening hours of hot melt adhesive
2.3 Regulate the spacing of the glue roller and the plate.
2.4 Raise the temperature with plastic, or an appropriate increase in the volume of glue
2.5 To maintain the temperature of the room temperature, the temperature of the sheet and edge banding machine in the appropriate range
2.6 Periodically clean edge banding machine
2.7 Rated sheet size in accordance with the specifications of the edge banding machine
2.8 Use of more high-quality hot melt adhesive
3.Human operator
(1) Irregular plate appearance after edge banding
<1>Problems that may occur：1.1 Glue line is too obvious
1.2 The glue line appears discontinuous
1.3 Uneven sheet Edge
1.4 Sheet and veneer moisture content is too high
1.5 Internal integrity of the glue roller
1.6 The plates surface with debris
<2> Corresponding solutions：2.1 Appropriate to reduce the use of plastic
2.2 Determine the precision of the sheet is expected to open, to ensure that we must keep to the side of the plane 90 °
2.3 Ensure edge banding machine Roller pressure is evenly distributed, pressure direction and plate edges at a 90 °
2.4 Maintain warehouse ventilated and dry
2.5 Check glue roller and roll on the hot melt adhesive is uniform and neat
2.6 Clean up the plate before feeding
