Now more and more consumers choose to go to the store to buy fashionable and designed finished doors. However, as the "face" project of home, the door is the most important link that affects the renovation period. We must do our homework well before selecting wooden doors.
Before purchasing
Pay attention to whether the formaldehyde and moisture content of the product are qualified.
The detection of wooden doors mainly tests the formaldehyde emission of samples according to GB18580-2001 "formaldehyde emission limits in interior decoration materials man-made Board and their products" (national mandatory standards), and then refer to JG/T122-2000 "building wooden doors, wooden window (industry recommended standard) WB/T1024-2006 wood door industry standard tests 4 Properties of sample moisture content, dipping and peeling, surface bonding strength and sandbag impact.
Therefore, when purchasing, the owner mainly needs to understand the environmental protection performance of the product, such as whether formaldehyde exceeds the standard, as well as the moisture content, dipping and stripping index of the product.
Since most wooden doors use urea formaldehyde resin as adhesive when they are made, some formaldehyde that does not participate in the reaction will remain in wooden doors, which will be released to the surrounding environment during use. If the formaldehyde emission of wooden doors exceeds the standard limit, in the process of use, it will not be conducive to the human health of the occupants. Therefore, the state has made strict regulations on the formaldehyde emission of man-made Board for interior decoration and its products, issued mandatory national standard GB18580-2001, and stipulated that the formaldehyde emission of wooden doors is less than or equal to 1.5mg/L.
In addition, the differences of various brands are mainly reflected in three aspects: moisture content, dipping and peeling, and surface bonding strength. The moisture content index mainly affects the stability and deformation of the door and directly affects the use effect of the door. Wooden doors with too high or too low moisture content may have dry shrinkage, expansion, cracking, deformation and other phenomena in use, which will affect the service performance of the doors.
The index of dipping and stripping mainly reflects the bonding performance between various layers of wooden doors under humid conditions. The better the dipping stripping quality is, the better the gluing performance and moisture-proof performance are, and the longer the service life of wooden doors is. Otherwise, the gluing performance is poor, which affects the service life of products.
The above problems are related to the production process, small batch production, storage and transportation of wooden doors. Therefore, it is best for owners to choose products with mature brands when purchasing wooden doors.
When purchasing
Multi-Channel understanding of product brand information
It is reported that as the world's largest producer and consumer of wooden doors, there are more than 10000 production enterprises nationwide, and there are more than 3,000 wooden door production enterprises with a certain scale and mainly mechanized production, therefore, the owner may wish to follow the following four points when purchasing.
(1) learn more about wooden door classification, quality, after-sales service and other related knowledge through the Internet, quality inspection announcements, newspapers and other channels.
(2) it is best to choose well-known enterprises or brands in the industry. At the same time, the distribution unit can be required to provide quality inspection reports issued by authoritative departments, and purchase wooden doors in formal building materials supermarkets or professional building materials markets, thus ensuring more rights and interests.
(3) pay attention to the outer packaging of the product. Experts from building materials Machinery Institute of Fujian Institute of product quality inspection said that the packaging logo of qualified formal commodities should include information such as the brand of the product, the name of the manufacturer, the implementation standard, grade, address, production date, etc. Good enterprise products will also be equipped with standard product instructions and operating instructions.
(4) pay attention to the appearance quality of the product. Surface finishing veneer of wooden door with good quality should be free of obvious pitting, glue marks, scratches, indentation, layering, folds, worn-out, edge sealing and splicing gaps; the appearance of the paint surface should not have obvious paint film scratches, wrinkles and leakage of paint, etc., there should be no paint film peeling, pollution and paint film particles, and the hand induction at the Groove Line is smooth.
After purchase
Proper maintenance can prolong the service life of wooden doors.
Reasonable use and maintenance is an important way to prolong the service life of wooden doors. In the installation initial stage of using, we should try to increase the circulation speed of indoor air to eliminate the residual odor in the surface paint of door body; Usually, other decoration will be arranged after the wooden door is installed, special attention should be paid to avoid the pollution of decoration materials such as paint and glue; Avoid the impact and scratch caused by placing hard objects within the opening range of the door. Generally speaking, wooden doors conform to the suitable temperature and humidity for people to live in, and the relative humidity of indoor air should be kept between 40% and 80%.
Generally, users should do the following aspects when using and maintaining:(1) door panels and door set of wooden doors are made of wood or wood-based materials. Although they are treated with moisture-proof, however, it still cannot resist the long-term soaking of water. During daily use, contact with water should be avoided as much as possible.
(2) the buffer device of 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 on the door panel to install pendants or hang heavy objects, in order to avoid shortening the life span. Prevent the wooden door from abnormal impact. When opening and closing the door leaf, the strength should be moderate. Do not push too hard 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 be kept closed frequently, and the bolt should be inserted into the double door to prevent collision and damage; During the special period of heating, the door leaf should be kept in the open state, avoid the deformation of the door leaf caused by uneven temperature on both sides of the door leaf caused by heating. The covering material on the surface of the door panel not only has the function of decoration, but also bears the function of moistureproof and protection. If it is accidentally damaged, it should be repaired in time to avoid moisture entering and causing greater deformation of the door panel.
