1. What is a paint-free board?
Paint-free board is a decorative material that can be decorated without painting on the board. More specific boards, such as melamine boards and eco-boards, belong to paint-free boards. Because such a board is not painted, it can well avoid the harm of unhealthy gases and carcinogens to our health, so the paint-free board is very environmentally friendly and healthy. Paint-free board is mainly used for decorative materials in furniture manufacturing, indoor decorative materials and architectural decorative materials.
Second, the types of paint-free board
1, density boards are attached to both sides of the board core, and melamine is added to decorate the paint-free board. This kind of paint-free board is not environmentally friendly, and it is not allowed to hold nails repeatedly, because its internal stress is unbalanced, so it will easily lead to deformation.
2. The plywood is attached to the paint-free board of the board core substrate. But this paint-free board is easy to open.
3. Add the middle board to the board core, and then paste the paint-free board with melamine finish. Although this paint-free board has high adhesion and good stability, it will have high requirements for construction technology.
Third, PVC wire is sealed.
I believe everyone is familiar with the so-called card strip closure, that is, a U-shaped card strip with the same color as the paint-free board is directly attached to the cross section of the paint-free board and fixed with nail-free glue to protect the appearance. Of course, there is also a problem with the closure of the card strip, that is, the width of the card strip is higher than the width of the plate, so if you don't pay attention in the later use, the edge of the card strip will be damaged, and it is still more troublesome to maintain.
The carpenter of my friend's house didn't use the card to handle the edge closing and sealing. Instead, it is treated with PVC wire, and the construction method can be treated with nail-free glue or edge banding machine. The advantage of closing in this way is that it can be flush with the plate after closing, and it is not easy to be damaged in the later stage. I think this method is much more practical.
At the same time, in the head-on part, the master also used aluminum alloy edge sealing treatment, and then selected colors according to the overall decoration style of the home. After such treatment, the cabinet will look very high-grade. Of course, the service life is longer than that of wood thread. I didn't know I could do it until I saw my friend's master handle it like this. I regret it now. I blame myself for not knowing before. If I had known, I would have done it.
From the above situation, it is indeed a very good method to close the paint-free board with lines. In fact, there are many materials and colors about sealing lines. When decorating, you can go to the market and choose according to your own needs. Of course, the craftsmanship is also very important, because the craftsmanship will directly determine the effect after edge sealing. Therefore, we should also understand this point.
Four, paint-free board edge sealing skills
1. Hot melt adhesive film for adhesive edge sealing of paint-free board. It is a film product with or without release paper, which can be conveniently operated continuously or intermittently. Generally used for bonding various fabrics, paper, polymer materials and metals.
2. When using hot-melt film for edge sealing, first lay the adhesive side of the film down on the edge of the paint-free board, then iron it with an iron to make the film stick to the edge of the board, then tear off the release paper on the back and leave the film on the paint-free board. Then, the sealing edge of the paint-free board is attached to the adhesive film and ironed with an electric iron with the temperature less than 140 degrees. Finally, let it cool naturally before pruning. In order to avoid damaging the board surface, pay attention to the angle of 20 degrees between the plane and the board surface when trimming.
3. Another skill of edge sealing of paint-free board is to use special putty for automobile to treat the bonding surface. The basic method is to use putty as the base, and polish it after curing for 24 hours. In fact, it is also very simple and beautiful.
The above is not about the knowledge of paint-free board, including what is paint-free board, the types of paint-free board, and the edge sealing method of paint-free board. You should have no doubt about the paint-free board. Now more and more people attach great importance to health and environmental protection. Therefore, when buying furniture and building materials, environmental protection has become the primary condition. Under such high demand, paint-free board stands out and is welcomed by many consumers. Therefore, if you need to buy building materials, you may wish to choose paint-free board.
