In the production process of panel furniture, hot melt adhesive is a key material for edge sealing and splicing, and its usage directly affects the appearance quality and service life of the furniture. Incorrect operation not only leads to edge sealing, glue peeling, and edge warping, but may also increase rework costs. Therefore, mastering the correct use of hot melt adhesive is crucial for improving production efficiency and product quality.
1、 Choose the appropriate hot melt adhesive
The commonly used hot melt adhesives for panel furniture include EVA hot melt adhesive and PUR hot melt adhesive. EVA hot melt adhesive is suitable for edge sealing of most boards, with good fluidity and moderate price; PUR hot melt adhesive is suitable for high-end boards or products with high requirements for waterproofing and moisture resistance. After curing, it has strong adhesion and excellent weather resistance.
When choosing hot melt adhesive, it should be matched according to the type of board, the material of the edge banding, and the production environment. For example, it is recommended to use filler free EVA or PUR hot melt adhesive for materials such as highlight boards and PET boards to ensure that the adhesive fully wets the surface of the board and improves the bonding strength.
2、 Control equipment temperature and pressure
The melting temperature of hot melt adhesive is the key to ensuring the bonding effect. If the temperature is too low, the colloid cannot be completely melted, the flowability is poor, and it is prone to false adhesion; If the temperature is too high, it may cause colloid carbonization, discoloration, and affect aesthetics.
The pressure of the edge banding machine also needs to be adjusted reasonably. Insufficient pressure can cause the edge banding to not adhere tightly to the board, while excessive pressure may squeeze out the glue, resulting in uneven glue lines. The best operation is to adjust the temperature of the glue pot and the pressure of the pressure roller according to the process parameters provided by the hot melt adhesive manufacturer to ensure stable edge sealing quality.
3、 Surface treatment of sheet metal
The cleaning and drying of the surface of the board is a prerequisite for the adhesive strength of hot melt glue to be exerted. If there is dust, oil stains or moisture on the surface of the board, it will affect the penetration of glue and reduce the bonding strength. Before production, the surface of the board should be kept clean and dry, and the workshop temperature and humidity should be adjusted appropriately according to the environmental humidity to reduce moisture problems.
4、 Correct operating procedures
1. Heat the hot melt adhesive to the recommended temperature to ensure complete melting of the gel;
2. Adjust the pressure and operating speed of the edge banding machine according to the thickness of the board and the material of the edge banding tape;
3. During the edge sealing process, keep the board stable and avoid shaking or deviation;
4. After completing the edge sealing, allow the colloid to cool and solidify sufficiently to avoid stress before solidification;
5. Regularly inspect the glue pot, glue delivery system, and edge banding equipment to prevent blockages or temperature fluctuations.
