What is the internal material of the wooden door? Is it environmentally friendly? Here can be tested from three aspects;
First, try to choose manufacturers with good brand reputation. These manufacturers are standardized in scale, product quality and service system. Second, we can measure what the product structure is by checking whether the relevant qualification certification of the manufacturer is complete and true against the relevant industry standards.
Third, pay attention to the final inspection by looking at the internal material of the door lock hole before installation.
Wooden doors are generally divided into solid wood doors, solid wood composite doors, molded doors and ordinary plywood doors according to materials.
(1) solid wood door
Solid wood doors are made of natural logs from forests, which are dried, cut, planed, tenoned, drilled and milled at high speed. Solid wood doors are mostly precious wood, such as cherry, walnut and teak. The finished door after processing has the characteristics of no deformation, corrosion resistance, no cracking and thermal insulation. At the same time, the solid wood door has good sound absorption and effectively plays the role of sound insulation.
(2) Solid wood composite door
The door core of solid wood composite door is mostly made of pine, Chinese fir or imported filling materials, and the density board and solid wood veneer are pasted outside, hot pressed at high temperature and sealed with solid wood lines. Generally, high-grade solid wood composite doors are made of high-quality unlined wood as the core and solid wood veneer as the surface. Due to low density, light weight, easy control of moisture content, light weight of finished door, and difficult deformation and cracking. In addition, the solid wood composite door also has the characteristics of heat preservation, impact resistance and flame retardant, and the sound insulation effect is basically the same as that of the solid wood door.
(3) Molded wooden door
Die-pressed doors are favored by middle-income families because they are more economical, safe and convenient than solid wooden doors. The molded wooden door is made of two high-density fiber molded door skins with modeling and simulated wood grain by mechanical pressing.
Molded wooden doors are covered with wood and coated with "varnish" veneer, which keeps the decorative effect of natural texture of wood and can also be used for panel inlay, which is beautiful, lively, economical and practical. Die-pressing doors also have the characteristics of moisture resistance, small expansion coefficient and deformation resistance. After a period of use, there will be no surface cracking and oxidation discoloration.
(4) Panel door
Ordinary plywood decorative doors are made of solid wood as the frame, and both sides are glued to the frame with decorative surfaces (plywood, multilayer board and decorative plywood). This kind of door is light in weight and low in price, but it has good decorative effect and is widely used in home decoration.
