Things you must know about the selection of furniture edge Banding hot melt adhesive
Guide: When selecting the hot melt adhesive for furniture edge Banding, first confirm which type of hot melt adhesive is applicable, and then confirm the selected weight after confirming the material. If the weight cannot be confirmed, it needs to be confirmed by testing.
The furniture edge Banding hot melt adhesive belongs to the industry specific hot melt adhesive film product. According to its name, it can be known that it is a kind of hot melt adhesive film suitable for edge Banding of furniture and building materials. The furniture edge Banding hot melt adhesive is an environment-friendly, solvent-free thermoplastic adhesive. It is essentially different from the traditional solvent based edge Banding glue. However, in the current furniture and building materials industry, there are still two kinds of edge Banding methods!
1、 The adhesive used for traditional solvent based adhesive edge Banding traditional furniture edge Banding and bonding between plates is solvent based adhesive, which is also known as glue. It can be said that the use method is relatively simple. Spray glue evenly on the surface of the board, and then cover the other side of the board and press it flat. When the glue is dry, it will be pasted. The same is true for edge Banding. Brush glue on the edge of furniture, and then stick the edge Banding strip and press it flat. The operation process of furniture edge Banding is common in home decoration. After the carpenter completes the closet and wardrobe, he needs to seal the edges, which are generally sealed with solvent based glue.
2、 The process of using hot melt adhesive for edge Banding is slightly more complicated than that of using solvent based glue, because the hot melt adhesive needs to be heated to a certain temperature first to make the hot melt adhesive change from solid state to molten state. When it is coated on the surface of the wood-based panel substrate or edge Banding material, the cold state becomes solid, and the material is bonded with the substrate. The advantage of hot melt adhesive for edge Banding is that it is more environmentally friendly than solvent based adhesive. The hot melt adhesive film needs to be melted at high temperature during processing and production, which makes harmful substances volatilize. Although high temperature melting is required again during product compounding, no harmful substances will volatilize. The furniture materials compounded with solvent based glue will cause long-term volatilization of harmful gases, such as formaldehyde, benzene and other harmful substances, which will easily cause indoor air pollution.
3、 Selection of the type of hot melt adhesive for furniture edge banding Common words The hot melt adhesive for furniture building materials includes EVA hot melt adhesive, TPU hot melt adhesive and PA hot melt adhesive. The characteristics of hot-melt adhesives of different materials are also different. According to different composite requirements, select the hot melt adhesive of corresponding materials. It should also be noted that the weight of hot melt adhesive used for different bonding strengths is not the same. For example, the bonding strength of 18g EVA hot melt adhesive for edge bonding and 20g EVA hot melt adhesive for edge bonding will vary a lot. When selecting the hot melt adhesive for furniture edge Banding, it is necessary to first confirm which type of hot melt adhesive is applicable, and then confirm the selected weight after confirming the material. If the weight cannot be confirmed, it needs to be confirmed by testing.
