An important step in the decoration process is the artificial veneer, which can complete the complex shape that the machine can't do. However, in the process of skinning, there are often cases of foaming. If the iron is used after blistering, it will cause cracking. How to avoid these situations and better complete the work of furniture decoration? Dry goods are coming!
Reasons for foaming and cracking of veneer
Analyze the causes of foaming and cracking of veneer carbonized furniture. The above conditions are roughly the following in operation:
1. The bottom of the substrate is not flat, that is, the substrate of the MDF is not polished and the appearance is not flat.
2. The veneer used is too thick, while the veneer is not wet. Usually the thickness of the veneer is less than 0.3mm. It is very difficult to apply too thick a craft, and it is simple to ask.
3. The temperature of the iron is not well controlled, usually the temperature is too low and simple foaming. In addition to the above doubts, the cracking in ironing is also related to the excessive ironing temperature, too frequent ironing times, and too short intervals.
4. Glue doubts, the use of substandard glue, resulting in no glue, perhaps not evenly coated. Therefore, the choice of high-quality glue is the key to sticking veneer.
How to paste veneer
Analyze the above reasons, then we should pay attention to avoiding the blistering and cracking of the skin:
1. The substrate treatment is flat. It is important to select a flat surface with no deformation.
2. The veneer of the craftsmanship should be 0.2 mm, and try not to exceed 0.25 mm.
3. The temperature of the iron should not be too low. Of course, it can't be too high, and the temperature should be suitable.
4. The viscosity of the glue should be suitable, the solid content should not be too low, too thin and not sticky, simple foaming, uniform glue, pay attention to the quality of the glue.
5. The veneer should be infiltrated, and then dried to dry humidity suitable for reuse. The veneer cannot be wetted by carbonized furniture, which of course requires practical experience.
6. The end face or curved face should be ironed repeatedly and pay attention to the interval.
7. The end veneer should not be cut by the blade as much as possible, and it should be ground with a wooden board pad. There are also more experiments, standardization of operations, and the cultivation of careful professional operators.
