First, the solid wood door
The solid wood door material is taken from the natural logs of the forest, mostly precious wood, and the raw materials are increasingly scarce. Pure natural pollution-free, low-carbon, environmentally friendly.
Second, solid wood composite door
The solid wood composite door is a solid body or a nearly solid body made of wood, glue and the like as a main material, and the surface layer is a wooden veneer veneer or other covering material. Variety of styles and rich styles.
Third, the paint-free door
As far as the name suggests, the paint-free door is a wooden door that does not need to be painted. Most of them refer to PVC veneer doors. The outermost part of the solid wood composite door or molded door is made of PVC veneer vacuum blister processing.
Fourth, the paint door
The paint door is mostly made of MDF as the substrate, the back side is melamine, and after painting, the paint door is heated and dried in the drying room. Bright color, good surface finish, easy to scrub, good moisture and fire resistance, but the process is complex, the processing cycle is long, and the price is relatively high.
Five, molded door
The molded door is made of wood of artificial forest, which is peeled, sliced, screened, ground into dry fiber, mixed with phenolic glue as binder and paraffin, and then molded at high temperature and high pressure. The door panel is hollow, and the sound insulation effect is worse than that of the solid wood door, and it cannot be wet and bumped. The same is the wooden door, why is the price difference so much? I saw the "core" to know! The core material of the wooden door largely determines the quality of the wooden door. Which core materials are currently on the market: particleboard, fiberboard, honeycomb paper, thin core board, pure solid wood panel
Particle board
The particle board is mainly made of wood scraps, which are glued together by glue and form a certain thin plate by extrusion.
Advantages: This material is mainly cheaper and the material source is better.
Disadvantages: the load bearing is relatively poor, so the extrusion is not very good, the normal wooden door internal filling is not recommended to use particle board, so it is easy to deform when exposed to water, and is not soundproof.
Application: So it is easy to have after-sales problems during the use process, but some merchants will replace the internal core material with cheap particleboard in order to save money. Therefore, pay attention to the purchase of brand wooden doors during the purchase.
Fiberboard
It is mainly made of wood fiber or other plant fiber, and is made of glue to make artificial core material.
Advantages: moderate density, good dimensional stability and small deformation.
Disadvantages: Because many merchants produce some low-density boards in order to save money, the pressure resistance of the boards is not the same, so the sound insulation effect of the wooden doors is poor, and it is susceptible to cracking or deformation problems in the later stage.
Application: The rational use of wood for fiberboard can reduce deforestation without protecting the ecological environment.
Pure solid wood panel
Pure solid wood panels use wood as the core material for the entire panel and are completely added.
Advantages: The cost of pure wood-filled wooden doors is relatively high, the wood texture is uniform, and the bearing capacity is relatively strong.
Disadvantages: Because the cost of the wooden door of this material is relatively high, the requirements for the production process of the wooden door are relatively high, so it is relatively rare in the wooden door.
Application: In the purchase, it can be identified by sound, etc. The sound of pure solid wood wooden door is relatively dull, and it will be accompanied by a certain thick feeling, and the weight is also heavy, so it can be used as a reference in the purchase. standard.
Thin core board
The thin core plates are mainly made of composite veneers, which are mainly adhered by glue and then processed by a hot pressing process.
Advantages: This kind of thin core board is more common, the thickness of the board is not equal, and the cost is relatively cheap.
Disadvantages: It is prone to cracking of glue during use, and the use of glue for bonding is prone to excessive formaldehyde content, so it is not very environmentally friendly.
Application: Select the fine core board (plywood) to pay attention to the following points
1. Plywood should not be damaged, bruised, bruised, or smashed.
2. Plywood has the difference between front and back. When selecting, the plywood should have a clear wood grain, a smooth and smooth front surface, and no roughness.
Honeycomb paper
Honeycomb paper is made according to the principle of honeycomb structure in nature. It is a method of bonding corrugated paper into a myriad of hollow three-dimensional regular hexagons to form a whole force-carrying paper, and bonding the paper on both sides. A new type of sandwich structure for environmentally friendly energy-saving materials.
Advantages: light weight, less material and low cost.
Disadvantages: Honeycomb paper is very deadly, its anti-destructive performance is poor, it is very easy to destroy, moisture resistance is also very poor, and it is easily deformed by moisture. Therefore, the life of wooden doors using honeycomb paper as the core material is generally short.
Application: Honeycomb paper is made of flexible paper core and paper, with good toughness and resilience. The unique honeycomb sandwich structure provides excellent cushioning performance and higher energy per unit volume in all cushioning materials. Absorbance, high-thickness honeycomb paper can replace the EPS plastic foam cushion that has been used in large quantities.
