In the production of panel furniture, edge sealing is a very important process that uses zui frequently, and it is also a process with many product quality problems. To judge the quality of a piece of panel furniture, it is easy for Zui to see the quality of edge banding. The quality of other links of enterprises that can do well in edge banding is generally not poor. Common methods and materials for edge banding: linear edge banding, irregular edge banding (soft forming edge banding) and post forming edge banding are widely used for edge banding of modern panel furniture. Among them, Zui usually uses straight edge banding. As long as the edge sealing material used as the base plate conforms to: strip or tape

The imported vacuum suction plastic has many advantages. First, it has strong environmental protection performance, harmless, no odor, no reactivity, no formaldehyde and other harmful gases; Secondly, it has adjustable hardness, high temperature resistance and good elasticity; In addition, it has special adhesive properties, low viscosity, good spray and good bonding properties. In view of the growing demand for vacuum suction plastic in the market, Lego vacuum suction plastic has a wide range of models and uses. It can be applied to the PVC film covering of cabinet door panels and sliding doors, as well as products with high requirements for adhesives, such as high gloss panels, high gloss films, etc., with high degree and high heat resistance.

The main reasons for the edge degumming after plastic suction forming are as follows: 1. The set activation temperature is low; 2. The workpiece is placed too close; 3. The amount of sprayed plastic is uneven or the amount of glue is too small; 4. The heat resistance of glue is too poor; 5. The initial adhesion of plastic suction glue is poor; 6. The table top of the plastic suction machine is too deep. The solution for the edge degumming after plastic suction forming is: 1 If the activation temperature of the adhesive layer is not reached, the adhesive film does not react before compression, and cannot produce effective bond strength, thus degumming. 2. If the workpiece is placed too close to each other, the leather cannot be effectively stretched and completely close to the lower part of the edge of the workpiece, resulting in the inability to completely wrap the workpiece. 3. Groove and corner position

There are only a few steps for furniture woodworking edge sealing, but if it is not done in a proper way, it may affect the effect of woodworking edge sealing. Needless to say, the importance of carpentry edge banding should be emphasized, and the standardization of its steps should be strictly observed. Woodworking edge sealing is a very important step in furniture manufacturing. The completion of every step is an expected signal to achieve a good edge sealing effect. Many small furniture factories do not pay much attention to the steps of edge banding when carrying out edge banding. As long as they can finally meet certain edge sealing requirements, this is the attitude of most small workshops. Although carpentry edge sealing is not complicated, it is just a few simple

1. First, spray the glue evenly to the edge of the wood through the spray gun. The amount of glue should be applied until there is a uniform layer of white glue on the wood. 2. After the glue dries naturally, it can be evenly discharged into the vacuum plastic machine. The standard of complete drying is that the white glue becomes transparent before, and there is no residue after gently pressing the fingerprint with your finger. 3. Then use the vacuum plastic machine to wrap the wood. Due to the different specifications of various equipment and the heat resistance of PVC skin, the heating temperature displayed on the vacuum plastic machine is different and varies widely. However, it is generally subject to the plane temperature of the actual wood, which is generally

Description, product features and precautions of vacuum suction plastic is a kind of waterborne adhesive polyurethane adhesive. Waterborne polyurethane adhesive is widely used in the market because of its water-based, harmless and convenient use. With the pursuit of low-carbon and environmental protection, a series of water-based adhesives have been developed. Vacuum absorbing plastics usually use polyurethane emulsion as the main component, which has good film forming performance and good heat and water resistance after crosslinking. A, Features of vacuum suction plastic: 1. It is harmless, safe, odorless, non reactive, free of formaldehyde and other harmful gases, and easy to clean; 2. Soft and hard

Analysis of various problems of edge bonding adhesive after use Lego Chemical Technology provides 1. Release after bonding ① Unqualified materials Release substances that cause degumming at the bottom of edge bonding. ② Unqualified PVC edge sealing primer (medium) is incompatible with hot melt adhesive. ③ The oily wood edge sealing is bonded with incompatible hot melt adhesive. ④ When wood veneer edge sealing is used as primer, the proportion of Tiannaoshui or other diluents is too large and the diluent is too strong, which causes the expansion of hot melt adhesive, and then the adhesive edge sealing will bond and loosen. ⑤ The reason is that the hot melt adhesive is cooled (sharply cooled) during the bonding process, and it should maintain stable bonding conditions, including temperature, pressure, and working speed

The specific operation process of vacuum plastic suction shows that Lego Chemical has been engaged in the production of vacuum plastic suction for many years. Lego vacuum plastic suction is mainly used for bonding computer desks, office desks, plastic doors, sound boards, cabinet boards and other plastic suction boards (pieces), and is widely accepted by the market with its advantages of high quality and high price. The rich experience summarized the operation process of vacuum plastic suction for reference. The vacuum plastic suction process includes roughly 12 steps: 1. First, the preparation of materials: MDF 1. Ensure the cleanness of the board surface, 2. For the cut MDF, the four sides should be polished with the finest sandpaper as possible. So during the glue spraying process

Analysis of the problem about the durability of hot melt adhesive for edge bonding and glue overflow This problem generally occurs in summer. Due to the hot weather, the temperature in some places has exceeded 40 degrees, and the edge bonding machine is still at the original temperature, which will lead to high glue temperature and strong glue fluidity (too thin glue), which will inevitably lead to more glue application in the edge bonding industry, Or glue overflow occurs. The reason for this problem is not that the edge bonding glue is not good. To solve the problem, reduce the temperature of the edge bonding machine by about 10 degrees, and then see if the problem has been improved, or open the glue box to see how the liquidity of the glue is. If it is not ideal, reduce the temperature again, and then

About the selection method of LEGO furniture hot-melt edge bonding adhesive products 1. After the bonding strength of furniture edge bonding adhesive is completed, tear the edge bonding tape to visually feel the tensile strength and observe how much wood chips the edge bonding tape sticks to, or conduct a tensile peel test. Under the same conditions (referring to the same edge bonding machine, edge bonding strip, operation method and environment), select products with strong tensile force. In general, the strength of high-temperature adhesive is stronger than that of low-temperature adhesive. Bonding strength is a fatal factor affecting the quality of edge banding. 2. Initial adhesion strength and affinity The initial adhesion strength and affinity of hot-melt adhesives of different brands (Leguma brand) are different to some extent. The adhesive with high initial adhesion strength is helpful to enhance adhesion
