>>> Cabinet knowledge: selection of cabinets and process identification
Some hanging cupboards and closet doors will bend and deform after being used for a period of time, and they cannot even be opened or closed. Why does this happen? This boils down to the indispensability of a "water":
(1) The wood moisture content is too low or too high. If the moisture content is too low, it will swell and deform after absorbing moisture; the moisture content is too high and it will shrink after drying.
(2) Painted on the front of the door leaf, not brushed on the inside, not brushed on one side of the wooden material due to single-sided moisture absorption, dry evaporation, so that doors and windows bending deformation. Coupled with the general hanging cupboard, closet doors and windows are relatively thin, the thinner the more you can not withstand the impact of the external environment, easily deformed.
(3) Because of the material of the wood itself, the door is deformed with the change of moisture content and temperature.
In view of the above situation, the control of these aspects should be strengthened during the production of hanging cupboards and closets.
The moisture content of wood is generally controlled at about 15% in areas with relatively high air humidity in the south, about 12% in the northern and relatively dry areas, and generally not less than 8% in order to avoid the influence of moisture absorption. switch.
The purpose of brushing paint is to protect the wood from the external environment. Therefore, the inside and outside of the cabinet, the closet door, and the top and bottom of the door should be painted. If the plastic surface, then it should be fully posted.
In addition, the thickness of the door leaf should not be less than 20mm. The material used to make the door leaf should adopt blockboard and multiple sandwich plates. If wood is used, avoid using easily deformable wood (such as manchurian ash) and parts (such as the edges of round logs).
