Since the door is painted, the door is painted, the door The core plate is generally inlaid. Two consequences:

One is that moisture will enter and exit the wood from here, causing the expansion or contraction of the wood;

The second is that when the door core plate shrinks, it will expose the unless paint in the groove, which will produce ugly white edges. P> So why does the solid wooden door selling in the market not cause such problems? :

This is the cross-section of high-end solid wooden doors on the market. We can see that and traditional and traditional Compared with the approach, there is almost no complete material for this solid wooden door. Even if there is, it is tightly wrapped in inside and outside. Is the tofu residue project? No, this is the various efforts of the manufacturer\’s efforts to maintain the stability of the wooden door, and these efforts happen to bring another benefit, which is to reduce the cost.

Regardless of whether If you believe it or not, most of this cost reduction will directly reflect in product prices. The courage of the year

I have seen a local tyrant. The core plate is 7.5cm, carved by hand, and a door weighs more than 200kg. What about the market? Therefore, reducing costs within a reasonable range is actually a win -win situation. In fact, all methods are to ensure the stability of the wooden door, we explain it in detail.

It can be seen from the bottom that the structure is like sandwich biscuits. This is the principle of different contraction rates between different wood species and different thickness to hold each other to achieve a balance. </P.

The picture on the right is the form of small material stitching. There will be a difference, the reason is here. At the same time, it also has an important advantage that the annual wheel direction between the wooden bar is different, so the trend of deformation is different, which is more balanced.

Remember When I was a kid, there was a text, swan, prawns, and canarfish.The car, the direction is different, causing the car to move. This principle is used here.

Then there is a door core board. The door core plate is also a sandwich structure. There are usually two ways. One is three layers of wooden boards staggered horizontally, like an ultra -thick triple board. The second is the density board in the middle, with wooden boards on both sides.

The first price will be much more expensive. Because the wood -cut sheet is very large, except for the simply guarantee of 100%solid wood gimmick, it is of little significance.

The second price is relatively cheaper, and the effect will not be too worse.

There is also the third, that is, the door core board is completely density board with wooden skin on the surface. This process is used more on the kitchen cabinet door. Because the density board does not produce radial deformation, the stability is equally good. However, the moisture -proof performance of the density board is extremely poor. If the paint is not good, it will cause damage.

Putting the leather door core board is difficult to see that the method of trying is to look at wood grain. Because the door core plate will use milling out of the lace on the edge, the broken wood of wood fibers will appear. If the pattern is integrated with the panel, it can be considered as a pendant.

This is a complete set of solid wood door cross-section. Although Strong> Although this sandwich structure will save a little on the material, it takes more working hours, so the price will not be reduced, and sometimes it may be more expensive. /p>

Last summary

Everything in the world is a balanced result, and solid wood doors are not exceptions. . But after balance, it not only solved the problem of stability, but also greatly reduced the cost, and finally got a win -win result. Risk. Pollution.
