At present, there are many types of wooden doors on the market, and the name is also very confusing, which makes it difficult for consumers to purchase. Classification of wooden doors: wooden doors can be divided into three categories: all solid wood smashing doors, solid wood composite doors, and splint molded hollow doors. Correspondingly, the wooden doors are usually divided into: solid wood doors, solid wood craft doors, molded doors and ordinary plywood doors. Let us start with the production process of wooden doors to see the quality of various wooden doors.
First, natural wood insulation and sound absorption
Pure solid wood door:
It is made of natural logs from the forest, made by degreasing and drying, and then processed by cutting, planing, boring, eye-catching, high-speed washing and other processes. Pure solid wood doors are mostly made of precious wood, such as cherry wood, peach, walnut, rubber wood, gold teak, oak, etc., with no deformation, corrosion resistance, no seams and thermal insulation. At the same time, the solid wood door has good sound absorption and effectively plays a soundproofing role. The high-grade solid wood door has a relative moisture content of about 8%, which is not easy to crack and deform, and the use time will be longer. However, since it is made of natural wood monolith, there are disadvantages such as relatively large color difference and slight shrinkage seam.
Solid wood craft door
The door core is mostly made of pine wood, fir, etc., and is attached with MDF or Liuan board. The veneer is made of solid wood veneer, which is made by high temperature and hot pressing, and is sealed with solid wood lines. Advanced solid wood craft door, door core with high quality fir, surface hot pressed 45-60 silk natural veneer (equivalent to more than three times the veneer). Because the density of Chinese fir is small, and it is easier to control the water content, the finished door has good stability and is not easy to crack and deform. In addition, the solid wood craft door also has the characteristics of heat preservation, impact resistance, flame retardancy, etc., and the sound insulation effect is basically the same as that of the pure solid wood door.
Second, compression molding high-density simulation
The molded door is mechanically pressed from two high-density fiber molded door panels with styling and simulated wood grain. The molded door panel is made of wood of artificial forest, which is peeled, sliced, screened, ground into dry fiber, mixed with binder and paraffin, and molded at a high temperature. From this process, the molded door also belongs to the plywood door, except that the door panel is made of high-density fiber molded plate.
Plywood process is light and low
The ordinary plywood door is made of wood, perforated plate, high-density board, etc., and the flat parts on both sides of the door are pressed and pressed on the frame by the decorative panel, and the groove part is pasted with veneer or paper skin, and processed. This kind of door is light in weight and low in price, but it is limited by the process, and the surface color difference is large. Only the veneer, paper skin or nailed wood edge can be attached around the door.
The door has a variety of choices, which is a good news, but there are so many varieties, there is no standard rule, it is bound to bring confusion to consumers, making it difficult for Chinese wooden doors to go to the world.
Anti-Aging Masterbatch, also name UV Masterbatch,makes through optimization of composite processed by selecting efficient light stabilizer and antioxidant, used in plastic processing of PE,PP,ABS, can effectively reduce the heating oxidation caused the explanation effect in plastic products processing, and greatly relieved degradation caused by ultraviolet light irradiation in plastic products using processing, then significantly improve the anti-aging properties of plastic products, prolonging the service life.
