This article shares the practical application of B681-2 hot melt adhesive for pocket spring bags in the production of independent pocket spring bags, focusing on the semi-automatic production scenario. It details the product's usage parameters, gluing effect, and performance, providing a reliable bonding solution for the production of independent pocket spring bags with semi-automatic equipment.
- Applied Product: Independent pocket spring bags (special independent pocket springs for mattresses)
- Adapted Material: Non-woven fabric (special wrapping fabric for independent pocket spring bags)
- Production Equipment: Semi-automatic independent pocket spring bag production equipment
- Operating Temperature: Around 160℃ (stable melting, suitable for semi-automatic equipment operation)
- Gluing Method: Spray gluing (uniform atomization, no stringing, no glue overflow, suitable for the rhythm of semi-automatic production)
Combined with the semi-automatic production process, through performance tests at different time periods, B681-2 hot melt adhesive has a stable application effect, which is fully suitable for the production needs of independent pocket spring bags. The specific performance is as follows:
- Adaptability to Production Efficiency: The independent pocket spring bags required for one mattress are completed every 15 minutes. When the spring bags are offline from the equipment, the glue layer is basically completely cured; no additional curing time is needed, which effectively matches the semi-automatic production rhythm and does not slow down the production progress.
- Initial Bonding Performance: 30 minutes after gluing, the viscosity of the glue layer reaches a stable state, with firm bonding and an achievable material failure effect (the non-woven substrate tears, and the glue layer does not detach, proving that the bonding strength is better than the substrate itself).
- Medium-term Bonding Strength: After being placed for 4 hours, the viscosity of the glue layer is significantly improved, the bonding strength is further enhanced, and a large external force is required for material failure, which can effectively ensure the structural stability of the independent pocket spring bags.
- Long-term Service Performance: After being placed for 12-24 hours (one night), the glue layer has no embrittlement when pressed, and the glue line remains soft when folded, without fracture or degumming. It can withstand the extrusion and vibration during the use of the mattress for a long time, avoiding degumming and abnormal noise of the spring bags.
B681-2 hot melt adhesive for pocket spring bags is suitable for semi-automatic independent pocket spring bag production equipment. Under the operating temperature of around 160℃, the spray gluing effect is good, without stringing or glue overflow; the glue layer cures quickly, which can match the semi-automatic production efficiency, and the bonding performance at different time periods is gradually improved. Finally, it achieves the high-quality effects of strong adhesion, pressure resistance, no embrittlement and no glue breakage, with up-to-standard material failure rate. It can effectively ensure the bonding reliability and service life of independent pocket spring bags, adapt to the mass production needs of mattress independent pocket spring bags, and is the preferred hot melt adhesive product for bonding independent pocket spring bags in semi-automatic production scenarios.
