Home decoration, choose wooden doors, do not blindly

When buying wooden doors, many owners are very confused. In order to save time, they often choose a door. In fact, wooden doors still occupy a very important position in our home life, so we buy wooden doors. When you want to remember to blindly buy. The following Xiaobian is very honored to have two home improvement experts Wu Chenxi and Zhang Penglai and we explain how to scientifically purchase wooden doors.

1. Buy a door and buy a solid wood door

“Chinese people tend to love solid wood products for ten minutes, but they ignore the natural properties of wood.” Wu Chenxi pointed out that the stability of solid wood doors is not strong, and it is easier to produce door deformation, splicing and surface than other types of doors. Cracking and other phenomena. In fact, the performance of solid wood composite doors with good environmental performance is not worse than that of solid wood doors, and even the stability will be better than solid wood doors.

2. The heavier the door, the more solid wood door

“It is impossible to judge the inherent quality of the product from the weight alone.” Zhang Peng pointed out that the weight of the particleboard is sometimes heavier than that of the solid wood. “Although the raw material used to make the particleboard is broken wood, it is applied during the production process. Many adhesives, which account for a considerable proportion of the adhesive after curing, result in a component that is not light.” In addition, due to the difference in the size and thickness of the door leaf and the filler of the door core, it also causes the weight of the wooden door to be different. Therefore, the specific weight is not the most reasonable basis for judgment.

3. Shop around, choose cheap

“Wooden doors are not the same as other goods. Consumers can only see the surface of the door, and the internal quality cannot be judged.” Zhang Peng pointed out that even if it is an expert, it is sometimes difficult to judge the internals of the wooden door simply by observing the appearance. Consumers are advised not to only look at the price of the cheap, but ignore the inherent quality of the product. Wu Chenxi pointed out that the environmental performance of the door is extremely critical. "Consumers and their cheaper solid wood composite doors, it is better to choose expensive paint-free doors, so environmental protection is more secure."

4. Judging the door core material through the door lock hole

Some "smart" consumers observed that the door lock of the wooden door was installed on site. "Why don't you use the door lock to keep the hole in the door to observe the core material of the purchased wooden door?". However, Zhang Peng pointed out that in the manufacturing process of wooden doors on the market, in order to make the locks more secure after installation, the strength of the door lock hole area will be strengthened, and most of them are lining laminated materials, so the door lock is retained. It is not very realistic to inspect the core of the wood door.

5. Focus only on the door leaf, don't care about the door cover

When consumers choose wooden doors, they often only pay attention to the quality of the door leaf. However, Yang Bin pointed out that many of the after-sale problems of wooden doors are actually from the door sets. There are three kinds of solid wood multi-layer door covers, MDF door covers and solid wood door sets on the market. The waterproof and moisture-proof performance of the MDF door cover is relatively poor, and it is easy to cause the wooden door to sink and scrape. The solid wood door cover is generally tooth-joined, and the screw is easy to form a smashing phenomenon. She pointed out that the best choice for solid wood composite doors is the standard door panel with solid wood multi-layer board, which can guarantee the service life of wooden doors.

6. Never allow color difference

Zhang Peng said that some of the consumer complaints received by the association are concentrated on the issue of color difference. "The problem of color difference can't be completely avoided." Zhang Peng explained that, for example, the paint-free door of the same suit may have different colors due to different factory batches of the cover material, and consumers may see it in the store. The color is slightly different from that at home. The paint door of solid wood veneer is even more so. The parts of solid wood veneer are different, the age of the wood is different, and the color of the cut pattern is not the same. "The same is black walnut, and some may have darker colors, which may be shallow. This is caused by the natural properties of the wood; the difference in the number of paint passes and the difference in the color of each paint may cause slight deviations in color, so consumers cannot excessively pursue the color difference of the wooden door."

7. If the wooden door cracks, it is required to return the goods.

"From the perspective of protecting the environment and conserving resources, it is recommended that the problems of wooden door products be based on maintenance." Zhang Peng explained that it is normal for the paint door to appear fine cracks. "The wood has the characteristics of shrinkage and swelling, which is a natural defect of wood. This problem has been difficult to overcome since ancient times. The current technical means can only minimize the occurrence of cracks, but it is impossible to completely eradicate it." He pointed out that paint The small cracks in the door can be solved by maintenance. The return to the factory is not the only way. Some minor problems can be repaired in the consumer's home.
