Now more and more consumers choose to go to the store to buy stylish and design finished doors. However, the door as the "face" project of the home is the most important part affecting the renovation period. You must do your homework before selecting the wooden door.
Before buying
Pay attention to whether the product formaldehyde and water content are qualified
The wooden door detection mainly tests the formaldehyde emission of the sample according to GB18580-2001 "Inner decoration decoration material and its formaldehyde release limit" (national mandatory standard), and then refer to JG/T122-2000 "Building wooden door, wooden window 》(Industry Recommended Standard) WB/T1024-2006 "Wooden Door" industry standard tests four properties of sample moisture content, immersion peeling, surface bonding strength and sandbag impact.
Therefore, when purchasing, the owner mainly needs to understand whether the environmental performance of the product, such as formaldehyde, exceeds the standard, as well as the moisture content of the product and the immersion and peeling index.
Since most of the wooden doors are made of urea-formaldehyde resin as the adhesive, the wooden door will retain some formaldehyde which is not involved in the reaction. It will be released to the surrounding environment during use. If the formaldehyde emission of the wooden door exceeds the standard limit, it will be disadvantageous during use. The human health of the occupants. Therefore, the state has made strict regulations on the amount of formaldehyde released from wood-based panels and their products for interior decoration and decoration, and introduced the mandatory national standard GB18580-2001, and stipulated that the formaldehyde emission of wooden doors is ≤1.5mg/L.
In addition, the differences between the brands are mainly reflected in the three aspects of water content, dip peeling and surface bonding strength. The moisture content index mainly affects the stability and deformation of the door, and directly relates to the use effect of the door. Wooden doors with too high or too low moisture content may cause shrinkage, expansion, cracking, deformation, etc. during use, which may affect the performance of the door.
The immersion peeling index is mainly reflected in the gluing performance between the various layers of the wooden door under wet conditions. The better the impregnation and peeling performance, the better the gluing performance and moisture resistance, and the longer the service life of the wooden door, and vice versa, the poor bonding performance and the service life of the product.
The above problems are related to the production process of wooden doors, small batch production, storage and transportation. Therefore, when the owner buys wooden doors, it is best to choose a more mature brand.
When purchasing
Multi-channel understanding of product brand information
It is reported that as the world's first wooden door production and consumption country, there are currently more than 10,000 production enterprises nationwide, and there are more than 3,000 wooden door manufacturers with a certain scale and mechanized production. Therefore, when the owners are shopping Please follow the four points below.

At the same time, the distribution unit can be required to provide the quality inspection report issued by the authoritative department, and purchase the wooden door in the formal building materials supermarket or building materials professional market, and the rights are more guaranteed.
(3) Pay attention to the product packaging. Experts from the Building Materials Machinery Institute of Fujian Provincial Product Quality Inspection Institute said that the packaging mark of qualified formal products should include the brand of the product, the name of the manufacturer, the implementation standard, grade, address, date of manufacture and other information. Good corporate products will also be equipped with standardized product manuals and instructions for use.
(4) Pay attention to the appearance quality of the goods.

After purchase
Proper maintenance extends the life of the wooden door
Reasonable use and maintenance is an important way to extend the life of wooden doors. In the initial stage of installation and use, we should try to increase the circulation speed of indoor air to eliminate the residual odor in the paint on the surface of the door; usually, other decoration will be arranged after installing the wooden door, and special attention should be paid to avoid the pollution of decoration materials such as paint and glue; Avoid hitting and scratching by placing hard objects within the open range of the door. Generally speaking, the wooden door is compatible with the suitable temperature and humidity of the person living, and the relative humidity of the indoor air should be kept between 40% and 80%.
Generally, users should use the following aspects when using and maintaining: (1) The door panels and door covers of wooden doors are made of wood or wood-based materials. Although they are protected from moisture, they cannot withstand long-term immersion of water. In the process, contact with water should be avoided as much as possible.
(2) The shock absorber of the door body can only resist the impact within a certain limit. Avoid leaning against the door leaf or hanging on the door handle. Do not drill holes or hang heavy objects on the door panel to avoid shortening the life. Prevent the wooden door from being subjected to abnormal impact. When opening and closing the door leaf, the force should be moderate. Do not use too much force or the opening angle is too large. Repeated strong impact will damage the normal use of the door.
(3) Under normal circumstances, the door leaf should always be kept closed, and the double door should be inserted into the bolt to prevent collision and damage. In the special period when heating starts, keep the door fan open, avoiding uneven temperature on both sides of the door and fan due to heating. Causes the door leaf to deform. The covering material on the surface of the door panel not only has the decorative function, but also bears the protection against moisture and protection. If it is inadvertently damaged, it should be repaired in time to prevent moisture from entering and cause greater deformation of the door panel.
