How to properly use hot melt adhesive for furniture edge banding

The use of edge banding hot melt adhesives.

1 The temperature at which the edge is banded.

Since the performance of edge banding hot melt adhesive is affected by temperature, temperature is a very important indicator in the edge banding process. The temperature of the hot melt adhesive, the temperature of the substrate, the temperature of the edge banding material and the temperature of the working environment (the workshop where the edge banding machine is located) are all very important edge banding parameters. On the automatic edge banding machine, because the glue is applied to the substrate, the substrate with too low temperature will make the hot melt adhesive cured in advance, resulting in the glue can stick to the substrate, but the edge banding material cannot be firmly adhered to, and the temperature of the substrate is best kept above 20 °C.

The ambient temperature of the edge banding machine affects the curing speed of the glue. Factories often have edge banding problems during the low temperature season, due to the faster curing of hot melt adhesives at low temperatures and the shorter bonding time. If the feed speed of the edge banding machine cannot be changed (in most cases), the panels and edge banding materials must be preheated to ensure the quality of the edges.

2 Treatment of edge banding glue line.

The glue line between the sheet and the edge banding after edge banding can have a negative effect on the appearance of panel furniture. If the amount of glue is too large, the glue line will be obvious, and conversely, it will reduce the strength of the edge banding. For the phenomenon of discontinuous or uneven glue lines, there are many reasons, and the following factors should be comprehensively considered:

The cutting accuracy of the plate, the edge of the plate must be at a 90° angle with its plane; Whether the pressure of the pressure roller of the edge banding machine is evenly distributed and the size is appropriate, and the pressure direction should be at an angle of 90° with the edge of the plate; Whether the gluing roller is in good condition, whether the hot melt adhesive is uniform on it, and whether the amount of glue is appropriate; The sealed edge of the board should be kept in a cleaner place with less dust as much as possible, and the dirty things should be avoided from contacting the glue line during the finishing process.

The use of edge banding glue should first be divided into machines, manual machines - low-temperature edge banding glue. Semi-automatic machine - medium temperature glue, fully automatic machine - high temperature edge banding glue; There is also the need to choose the right glue according to the thickness of the edge banding, and the season and environment will also affect the use of the edge banding glue. It is recommended to try it before use, and by the way, I recommend Shanghai Wei Industrial Company.

Furniture edge banding hot melt adhesive is a kind of adhesive specially used for the pasting of man-made panels, it is an environmentally friendly, solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it changes from a solid state to a molten state, and when it is coated on the surface of the wood-based panel substrate or edge banding material, it cools and becomes a solid state, bonding the material to the substrate. Next, we will introduce the characteristics of furniture edge banding hot melt adhesive and the precautions for the use of furniture edge banding hot melt adhesive.

Features of hot melt adhesive for furniture edge banding.

1. The solid content is 100%, and there is a gap filling, which avoids the deformation, dislocation and shrinkage of the adhered parts caused by edge rolling, bubbles and blind cracking. Because it is solvent-free, the moisture content of the wood does not change, and there is no risk of fire or poisoning.

2. The bonding is fast, the interval between gluing and bonding is only a few seconds, the saw head and trimming can be completed within 24 seconds, no drying time is required, and it can be used for continuous and automated wood bonding lines, which greatly improves production efficiency and saves plant costs.

3. It has a wide range of uses and is suitable for bonding various materials.

4. It can be bonded several times, that is, the hot melt adhesive is coated on the wood, and when it does not meet the requirements due to cooling and curing, it can be reheated for secondary bonding.

5. There are high-temperature, medium-temperature, low-temperature and other furniture edge sealing hot-melt adhesives to choose from.

Precautions for the use of hot melt adhesive for furniture edge banding.

1. When the edge banding machine is not working, the temperature of the rubber tank should be reduced to about 150 °C, on the one hand, it can avoid the carbonization of the hot melt adhesive at the use temperature for a long time, keep the rubber tank clean, and will not cause the blockage of the glue supply system and reduce the heating performance; On the other hand, when re-working, the canister can be quickly heated up to the service temperature. In addition, more than 2 3 glue must be kept in the rubber tank, otherwise black carbonization will be produced around the rubber tank.

2. It is necessary to clean the rubber tank and rubber roller regularly, as excessive carbonization around the rubber tank and residue on the rubber roller will reduce the performance of the heating system and the rubber supply system.

3. If you want to remove the residual glue in the rubber tank, you can put a T-shaped object into the glue before the edge banding machine stops working, when the glue is still in a melting state, and wait for the glue to cool down completely, and then re-instruct Zhaoyan to heat it up, because the bottom of the rubber tank and the glue around it are first heated and melted, at this time you can use the T-shaped object to take out most of the residual glue. Then wash the residual glue with a 1:1 mixture of toluene and methylene chloride.

What is the hot melt adhesive used for furniture edge banding? In fact, it is very easy to understand, as the name suggests, you will know it! It is a binder specially used for the pasting of man-made panels, and the hot melt adhesive for furniture edge banding is a very environmentally friendly and solvent-free thermoplastic adhesive.

When heated to a certain temperature, it becomes molten, and when it is coated on the surface of a man-made sheet or edge banding material, it condenses into a solid state, bonding the material to the substrate tightly. Next, let's take a look at the characteristics of furniture edge banding hot melt adhesive and its precautions.

First, the characteristics of furniture edge sealing hot melt adhesive.

1. The bonding speed is fast, and it solidifies quickly after contact with the man-made board or edge banding material, and does not need to be dried and other procedures, which can be used for continuous, wood bonding flow or water distribution line, which not only improves the production efficiency, but also saves the cost of the plant;

2. According to the actual needs, you can choose different temperatures of furniture edge sealing hot melt adhesive;

3. If it is found that the expected bonding effect is not achieved, it can be reheated and then re-bonded.

2. Precautions for use.

1. If the edge banding machine is not in working condition, the temperature of the rubber tank should be kept at 150

c, one is to avoid the phenomenon of carbonization of hot melt at the use temperature for a long time, and the other is to quickly reach the use temperature when working again. In addition, the hot melt adhesive in the rubber tank should be kept above 2 3, because it can avoid the formation of black charcoal around the rubber tank. Answered.

2. The rubber tank and rubber roller in use should be cleaned frequently, because the carbonization and some residues on the four walls will not only affect the heating system, but also reduce the performance of the hot melt adhesive.

3. If you want to remove the residual colloid in the rubber tank, you should put a T-shaped object into the melting rubber tank while the edge banding machine is still working, and then heat the rubber tank after cooling, and then use the T-shaped substance to remove most of the residual colloid, and finally clean the residual glue with toluene and methylene chloride in a ratio of 1:1.

Furniture edge banding hot melt adhesive is mainly divided into two categories: EVA high, medium and low temperature hot melt adhesive and PUR hot melt adhesive, which is suitable for automatic and manual edge banding machines, with good feeding performance, good thermal stability, strong adhesion, and toughness and hardness of the adhesive layer. It can be used for fully automatic and manual edge banding or coating of PVC, pin melamine, polyester, resin-impregnated paper, veneer and other materials in furniture manufacturing.

1. Furniture should be glued at home. EVA (ethylene-vinyl acetate copolymer resin) based melt adhesive, this hot melt adhesive can be divided into filler and no filler. The use of EVA as the binder is the most common technology for the production of furniture edge banding, and its main limitation is its poor heat resistance.

2. The ambient temperature of panel furniture with EVA hot melt adhesive edge sealing should not be higher than 120°C; Pol Yamide (polyamide) binder hot melt adhesive, this hot melt adhesive has the characteristics of good heat resistance and fast curing, the main disadvantage is that it is expensive. Rush forward.

It is necessary to keep the adhesive surface clean every time, and the glue box of the edge banding machine should be cleaned frequently, and the requirements for the edge banding glue are different for different edge banding strips.

There are several analyses:

1. There is too much glue, so it will overflow, generally 1mm thickness is enough.

2.If you don't stick well, it may be that the temperature is not well controlled. Try and explore a few more times.

3.The biggest one may be that the quality of the glue is too poor.

1.Frequently check the surface of the gluing roller to remove impurities and ensure that the gluing is evenly applied;

2.Frequently calibrate the temperature of the temperature control system;

3.The temperature should be reduced by 30-40 during the working interval;

4.When the temperature of the environment and the material is around 15, the temperature of the gluing roller should be set to 215, and the temperature of the glue tank should be set to 210;

5.Unused hot melt adhesives should be stored tightly sealed to avoid contamination and moisture absorption.
