🪑Guidance on the use of adhesives in furniture industry
1. PUR hot melt adhesive (polyurethane hot melt adhesive)
Applicable scenarios: Furniture edging, veneering, laminating, etc.
Usage suggestion:
Preheating equipment: Ensure that the hot melt adhesive equipment is preheated to the recommended temperature (usually 120 ° C to 140 ° C).
Glue application method: Roll coating or spray coating is used to ensure a uniform adhesive layer.
Pressing time: After gluing, the pressing should be completed within the opening time, usually 30 seconds to 2 minutes.
Curing process: PUR hot melt adhesive is cured by reacting with moisture in the air, and complete curing may take 24 hours.
2. Edge Bonding Adhesive
Applicable scenario: Edge banding of furniture.
Usage suggestion:
Glue application temperature: Keep within the recommended temperature range and avoid being too high or too low.
Glue application amount: Adjust the glue application amount according to the material type to ensure the bonding strength.
Compression pressure: Apply appropriate pressure to ensure that the edges are tightly adhered.
đź‘• Guidelines for the use of adhesives in the textile industry
1. Hot Melt Adhesive Film
Applicable scenarios: seamless clothing, functional fabric lamination.
Usage suggestion:
Temperature control: Set the appropriate hot pressing temperature (usually 120 ° C to 160 ° C) based on the type of adhesive film.
Pressure and time: Apply uniform pressure, and the hot pressing time is usually 10 to 20 seconds.
Cooling treatment: After hot pressing, cooling treatment should be carried out to ensure firm adhesion.
2. Waterborne Compound Adhesive
Applicable scenario: Composite of fabric and film materials.
Usage suggestion:
Glue coating method: Use scraping or rolling coating to ensure a uniform adhesive layer.
Drying process: After coating, appropriate drying treatment should be carried out to avoid residual moisture affecting the bonding effect.
Composite time: Composite is carried out when the adhesive layer is dry and not sticky to the hands, ensuring the bonding strength.
đźš—Guidelines for the use of adhesives in the automotive industry
1. Lamp Assembly Glue
Applicable scenarios: Sealing and bonding of automotive lighting fixtures.
Usage suggestion:
Surface treatment: Ensure that the bonding surface is clean, dry, and free of oil stains.
Glue application method: Use glue or line glue to avoid the generation of bubbles.
Curing conditions: Control the curing time and temperature according to the product instructions to ensure sealing performance.
2. Waterborne Compound Adhesive
Applicable scenarios: body seams, door and window sealing.
Usage suggestion:
Glue application equipment: Use specialized glue application equipment to ensure even glue lines.
Curing time: Adjust the curing time according to the ambient temperature and humidity to avoid premature movement affecting the sealing effect.
Post treatment: After curing, necessary polishing or coating treatment can be carried out.
📦Guidelines for the use of adhesives in the packaging industry
1. Carton Glue
Applicable scenarios: carton sealing, carton bonding.
Usage suggestion:
Glue application temperature: Maintain within the recommended temperature range, typically 160 ° C to 180 ° C.
Glue application amount: Adjust the glue application amount according to the material and thickness of the cardboard box to avoid penetration or weak adhesion.
Pressing time: After applying the adhesive, it should be pressed immediately to ensure a firm bond.
2. Label Adhesive
Applicable scenarios: label pasting, barcode label bonding.
Usage suggestion:
Surface treatment: Ensure that the surface to be pasted is clean, dry, and free of oil stains.
Glue application method: Spray or roll coating is used to ensure a uniform adhesive layer.
Adhesive pressure: Apply appropriate pressure to ensure that the label is tightly adhered to the surface.
🔧 Equipment Setup & Maintenance
1. Hot Melt Appliator device calibration
Temperature setting:
· PUR：120–140 °C
· EVA：160–180 °C
· APAO/PSA：90–130 °C
Pressure and flow rate: Based on the equipment model and nozzle diameter, refer to the manufacturer’s recommended parameters to maintain smooth dispensing.
Nozzle cleaning: After each shift, use a dedicated cleaning agent to wipe the nozzle to prevent glue blockage.
2. Roller Coating&Lamination Machine Maintenance
Roller maintenance: Regularly check whether the roller surface is uniform. If there is adhesive layer accumulation, clean it with a non damaging cleaning agent.
Tension adjustment: Adjust the tension of the upper and lower rollers according to the thickness of the film and substrate to avoid stretching or wrinkling.
Temperature balance: Ensure that the temperature in the preheating zone and the pressing zone is stable to avoid poor adhesion caused by differences before and after.
🛠️ Common Troubleshooting
| Problem | Possible reasons | Solution |
| Insufficient adhesive strength | The glue temperature is too low; The substrate is not cleaned; The opening time is too short | Raise the temperature by 10 ° C; clean the surface of the substrate; Extend the glue opening time |
| Surface blistering or pinholes | Adhesive contains gas; The substrate humidity is too high | Use a defoamer to process the rubber material; Ensure that the substrate is dry |
| Rubber wire drawing | Excessive glue temperature; Insufficient adhesive pressure | Reduce temperature by 5-10 ° C; increase adhesive pressure |
| Edge raised | Insufficient bonding pressure; Insufficient opening time | Increase the compression pressure; Appropriately extend the glue opening time |
| Nozzle blockage | Failure to clean in a timely manner; Use low-quality cleaning agents | Using professional cleaning agents, thoroughly clean after work |
