Misunderstanding one: the quality of mortise joint is better

In the market, some salespersons will say when introducing the advantages of their own products that the wooden doors of other manufacturers may be spliced ​​and glued, while their own wooden doors are made of mortise, which is more environmentally friendly and has more stable quality. Le Si Fu fireproof decorative board tells you that it is better to do mortise joints?

Professional doubt: Tenon and tenon joint is a wood joining method invented by our ancestors for thousands of years, and it is still used in a small number of occasions. But it is not suitable for industrialized processing, let alone mechanized assembly line operation. If the solid wood door is combined with tenon and tenon and does not use any adhesive, it can be described as a more "environmental protection" concept, but it is also prone to deformation and cracking.

Misunderstanding 2: Pure solid wood is more high-quality and environmentally friendly

In the minds of many people, solid wood doors are definitely more environmentally friendly and the quality is relatively better due to the use of more solid wood materials.

Professional question: whether the glue used in the wooden door is environmentally friendly and whether the heavy metal content in the opaque painted wooden door exceeds the standard. From the point of view of production methods, solid wood doors may contain slightly less glue, but as long as they comply with national standards, they are environmentally friendly.

The finished solid wood door after processing has the characteristics of environmental protection, small deformation, corrosion resistance, resistance to cracking, heat insulation, etc., and also has good acoustic performance, which effectively plays a role in sound insulation. However, the quality of the craftsmanship of solid wood doors is very demanding, and the advantages are luxurious, beautiful and unique in shape. Through the fusion of modern precision craftsmanship and traditional hand-carving techniques, solid wood doors are more of an artistic value, but the market price is high, and they are high-end wooden door products.

Due to structural problems, solid wood composite doors have the characteristics of stability, small deformation, resistance to cracking, heat preservation, sound insulation, impact resistance, and flame retardancy. It solves the problem of cracking, deformation and shrinkage of the door core board due to seasonal changes, differences in average moisture content in different regions, inherent dry shrinkage and swelling of wood and various differences, as well as the white edge phenomenon caused by shrinkage around the door core board after painting. The materials and styles of solid wood composite doors are more diverse, giving consumers a wider choice of space.

Misunderstanding 3: Buying cheap goods is more cost-effective

"Pick the cheapest" is the consumer psychology of many people. When buying wooden doors, many consumers naturally think that the cheaper the better, the more cost-effective.

Professional troubleshooting: When buying wooden doors, you should carefully choose the cheapest product. Products that are lower than the normal market price are usually products that are overstocked by enterprises, trial-produced products, processed for some reason, or products whose quality may not meet the standard requirements. After using such a product for a period of time, there may be no quality problems, or quality problems may gradually be exposed. Most of the quality problems of low-priced wooden doors will gradually be exposed after several years of use, and once they occur, they are difficult to repair. On the contrary, high-quality products usually have a service life of 20-30 years or even longer. If you pay a reasonable price, you will get comfort and peace of mind during the whole process of using the wooden door.

Misunderstanding 4: The lower the release of formaldehyde, the better

When choosing wooden doors, many people require that the lower the amount of formaldehyde emission, the better. They think that the lower the amount of emissions, the more environmentally friendly wooden doors are.

Professional answer: The amount of free formaldehyde released is indeed the most important environmental indicator for wooden doors. Free formaldehyde is inherent in all wood-based panel products that use urea-formaldehyde resin glue as the adhesive. Just because free formaldehyde is harmful to humans, the country has issued a mandatory standard GB18580 "Indoor decoration materials, wood-based panels and their products formaldehyde emission limit". Strictly limit the release of free formaldehyde from wood-based panel substrates.

However, consumers should treat this environmental protection index in a correct way, and the release of free formaldehyde is not as low as possible. Free formaldehyde affects the strength of wood-based panel products to a certain extent, and the production of wood-based panels for wooden doors requires urea-formaldehyde resin glue as the adhesive. If the free formaldehyde is too low, the strength of the wooden composite door product is difficult to be guaranteed, and the quality is relatively poor. Generally speaking, compared with other large-area indoor decoration materials, indoor doors only occupy a small part, and the free formaldehyde release in the family only accounts for a small part. Therefore, as long as the free formaldehyde release meets the requirements of the national mandatory standards For interior doors, consumers can choose with confidence.
