Fire rate entri door, refers to the solid or close to the solid body made of wood and adhesive material, and the door of the veneer veneer or other covering material.
The door core of the MDF door is mostly made of pine, Cunninghamia lanceolata or imported filling material, and the outside density board and wood bark are made of high temperature hot pressing and sealed with solid wood lines. In general, the MDF doors are mostly high-quality white pine, and the surface is solid veneer. Because white pine is small in density and light in weight and easy to control moisture content, the weight of finished doors is lighter, and it is not easy to deform and crack. In addition, the 1 hour fire rated wood door has the characteristics of heat preservation, impact resistance and flame retardance, and the sound insulation effect is basically the same as that of the solid wood door.
In the MDF door, it is often used as the base material of common wood. It plays the structure connection and frame function to improve the anti deformability; the wood texture is ornamental and the thin wood made with precious tree species, which is used as the surface decoration material of the door, and can truly reflect the characteristics of the wood; the wood-based panel used is mainly medium fiber board. The material is uniform and the milling performance is good. It can be used as a molding component. Therefore, the solid wood composite door makes full use of the excellent properties of various materials and avoids the use of precious precious wood, which reduces the cost of production effectively without reducing the use and decorative performance of the door. In addition to good visual effects, it also has the characteristics of sound insulation, heat insulation, high strength, good durability and so on, which is accepted by people.
The new set of MDF doors is composed of three parts: door fan, door cover and door cover line. This kind of structure changes the variety of wooden door style, and solves the problems of easy deformation and cracking of all real wood doors. The whole set of MDF doors are manufactured in factories, and the installation is simple and quick. It avoids the air and noise pollution caused by painting on the door.
