The door core of the solid wood composite door is mostly made of pine, fir or imported filling materials. It is made of Osong board and solid wood veneer. It is made by high temperature and hot pressing, and is sealed with solid wood lines. Generally high-grade solid wood composite doors, the door core is mostly high-quality fir, and the surface is solid wood veneer. Due to the high density, light weight and easy control of water content, the finished door has a light weight and is not easily deformed or cracked. In addition, the solid wood composite 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 solid wood door.

In addition to good visual effects, it is also accepted by people with its characteristics of sound insulation, heat insulation, high strength and durability.
The new set of solid wood composite door is composed of three parts: door leaf, door cover and door sleeve line. This structure makes the wooden door style change variously, and solves the problems of easy deformation and cracking of the solid wood door. The complete set of solid wood composite doors are factory-made, which is quick and easy to install, avoiding the air and noise pollution caused by the painting on the construction site.
Door variety
By face material
There are mainly walnut, cherry, sapele, shadow wood, maple, teak, ash, ebony, rosewood, crape myrtle, zebra, science and wood, pine, fir and so on.
By function
There are mainly bedroom doors, study doors, kitchen doors, apartment doors, corridor doors, office and commercial doors, hotel doors and so on.
By way of opening
1. Slide rail door: It is opened horizontally and does not take up space. Mainly used for kitchen doors, bathroom doors, balcony doors
2, hinge door: steering open, mainly used for entry doors, bedroom doors, office doors.
By surface treatment
1. Baiqimen: There is no door to paint. After buying it, you need to find the oil painter to paint it by hand. Because of the brushing of the hand, the quality of the door is lowered.
2, paint door: also known as the finished door, the paint door has been painted in the factory, can be installed directly.
By door form
1. Flat door: The edge of the door is flat. The traditional door is all flat door. Due to the opening of the lock, there must be a gap of 3 mm between the door and the door frame.
2, T-port: a new type of door imported from Europe, the edge of the door is a T-shaped mouth, the protruding part is pressed on the door cover, and is equipped with a sealing strip, the sealing sound insulation effect is good, the overall appearance is beautiful.
By door type and process
1. Plate type door: It is closed type, no perspective light transmission point, and is mostly used for door and bedroom door. This door can engrave concave line and make convex line. The shape is beautiful and generous, and the integrity is good.
2, core board door: in the middle of the door is equipped with one or more core boards, convex, three-dimensional artistic.
3, full glass door: glass door as the main door, the door has only four sides and dock, the rest are made of glass, with bright light, good permeability, rich in artistry and appreciation.
4, half glass door: the above half is glass, the lower half is plate type, with proper transparency.
Craftsmanship
The door leaf adopts the frame of fir integrated timber. It needs to be thickened and sanded and pressed 3 l"nn.1 thick MDF. After thick sanding, hot pressing and covering the veneer is good for the unevenness of the substrate in the original process, resulting in stickers. The back surface of the veneer is corrugated. The door core plate adopts the peripheral end face milling type to make the door leaf more three-dimensional. The pressure plate is used to fix the door core plate, so that the door core plate has the replaceable thickness, and the original process core is improved. When there is a problem with the board, the problem of replacing the entire door leaf is required.
The manufacturing process of the door cover adopts the balance structure of double-sided pressing of the MDF board to enhance the bending resistance, avoid the deformation of the door cover, the door closing is not tight, and the gaps around the door are not the same. The veneer finish ensures the same texture of the door leaf and door cover.
The door sleeve is made by vertical gluing of two MDF plates, which comprehensively utilizes the high longitudinal and transverse bending strength of the MDF. The wooden door cover after the improvement process is combined with solid wood and wood-based panels, the cost is reduced, the product quality is improved, the product structure is rational, and the surface is beautiful. This process has been tested and has been matured in production, achieving mass production and being recognized by the market.
Veneer: Since the inner material of solid wood composite door adopts ordinary wood and MDF, the use of solid wood veneer veneer is the most important process of solid wood composite door, which has a decisive effect on its final quality and use effect.
Wood and MDF glued wood and medium density MDF are bonded with adhesive. In order to ensure the quality of the glue, it is necessary to ensure the processing precision of the mating surface. In addition, it is necessary to select rubber grades with high bonding strength, such as urea-formaldehyde resin glue and poly Vinyl acetate emulsion, etc.
raw material
It is a medium-density fiberboard that greatly reduces the amount of wood used and is very environmentally friendly and low-carbon.
Core
The solid wood composite door is generally a five-layer hot-pressed composite structure. Most of the manufacturers' door core materials use fir laminated timber, and the higher-grade solid wood composite door adopts pine integrated pine.
Veneer
Since the inner material of the solid wood composite door adopts ordinary wood and medium-density board, the thin wood veneer is the most important process of the solid wood composite door, which has a decisive effect on its final quality and use effect.
Great production flexibility
1. Unloading a component to process a component finish to process an assembly. The process is characterized by first machining the components and surface treatment and then assembling them into a door. Since the finishing material is very thin and does not have the conditioning conditions, the processing precision of the components is required to be high.
2, a component is processed, one assembly is assembled, and one finish is processed to handle the corner. The process feature is that after the overall processing of the composite door is completed, the finishing process is performed, and the door blank can be trimmed before the veneering.
3. Make a door blank, a milling shape, and a finish. The panel of the solid wood composite door adopts a 18 mm thick MDF, and the milling cutter produces various concave and convex effects similar to the solid wood door, so that the shape is flexible and the selectivity is strong. By improving the above conventional process, the author proposes a more practical solid wood composite door processing technology.
Purchase instructions
According to the material
The material of the door panel and panel has a great influence on the overall quality. Honeycomb paper, large core board, imported door core board and other materials use different sound insulation effects. You should choose whether to use the door core board according to the specific functions and requirements. There are dozens of varieties of panels, such as oak, walnut, maple, rosewood and other different woods have their own natural texture and quality, should choose different types of panels according to the actual decoration style and preferences.
According to the structure
The high-quality finished door can be divided into two categories: flat structure and solid wood structure (including panel structure and panel structure).
From the appearance of the panel door and the panel door, the three-dimensional sense of the line, the shape is prominent, the weight is heavy and the cultural quality is displayed. It belongs to the traditional craft production, the workmanship is excellent, the structure is stable, the fly in the ointment is the high cost, suitable for European, neoclassical, New Chinese style, country, Mediterranean and other classic styles after time precipitation can be integrated into the entire building space, enhancing the purity of style decoration and the sense of history and culture.
The flat door has a simple exterior, a strong modern feel, a wide selection of materials, rich colors, strong plasticity, easy cleaning, and reasonable price, but the visual impact is weak. Suitable for modern, simple, avant-garde and other free, modern styles, can add vitality to the space. The flat door can also be used to shape the changing classical style by boring and milling, but the three-dimensionality of the lines is poor and lacks heavy feeling, but the cost is relatively moderate.
According to paint
1, look at, touch the fullness of the paint film, this will be more than a few times will be seen. The paint film is full, indicating that the quality of the paint is good, the polymerization power is strong, and the sealing of the wood is good. At the same time, the painting process is relatively perfect, and there is no suspicion of cutting corners;
2. Stand at the oblique side of the door to find the reflective angle of the facade, see if the paint film on the surface is flat, whether the orange peel phenomenon is obvious, whether there are fine particles protruding, if there are obvious small particles, the factory’s The painting equipment is relatively simple, at least there is no full-pressure dust-free paint booth, which is the necessary equipment to control the quality of the paint surface. If the orange peel phenomenon is more obvious, it means that the baking process of the paint film is not enough;
3, fancy modeling door, it depends on the edge of the line that produces the shape, especially the negative angle (that is, the angle that can not be seen), there is no cracking of the paint film.
4, ask the type of paint, the basic answer is PU paint (polyurethane paint), PU paint has the advantage of easy to polish, the process saves time and effort, the disadvantage is that the paint film is soft, slight bumps are easy to produce white shadow dents. If at least one layer of PE paint is in the paint layer, this possibility is greatly reduced. The advantage of PE paint (polyester paint) is that the paint film is hard, the hiding power is strong, the transparency is good, and the veneer texture can be better expressed. The disadvantage is that it is difficult to polish, and the processing process is time-consuming and laborious. Most manufacturers are not willing to use PE coating. This is also a good indication of a manufacturer's attitude towards products. Here to explain, the general promotion of the training will not involve this aspect, so at this point they are not very likely to deceive consumers, they themselves do not understand the difference between the two paints.
According to the flatness
1. The veneer is foamed, indicating that the veneer is unevenly heated during the attaching process, or the glue is not uniform, and the flat hot press can solve the problem of uneven heating when the flat door is pasted;
2, the flatness of the wooden door surface is not enough, indicating that the plate selection is relatively cheap, the flatness of the plate is not enough, it can be imagined that the environmental performance is also difficult to meet the standard, a little leaf Yiqiu means it;
3, see if the process seam is even and small
See if the joints of the craft are even and even, which is almost the same as the car, which directly reflects the comprehensive technical level of the enterprise;
4, see the quality of installation
Although the finished product door is finished in the factory, it is only finished when the product is handed over to the customer. Therefore, the factory is only a semi-finished product, and installation is a key link. A good installation process, good installation tools, and experienced installation technicians are the key to success. The installation of the hard door should be horizontal and vertical, the gap is even and small, the opening and closing is smooth, and it will not move automatically when it is opened at any angle (except for installing the door closer). The hardware such as hinges and door locks are fine and smooth. And horizontal and vertical.
Cleaning and maintenance
1. Don't hang heavy items on the door leaf or avoid sharp objects bumping or scratching. When opening or closing the door leaf, don't use too much force, don't hit the wooden door.
2. Do not open the door lock with wet hands or splash corrosive solvents onto the solid wood composite door and door lock. Do not use excessive force when opening the door lock or turning the door lock handle. Frequently moving hardware such as hinges, door locks, etc., should be tightened immediately when loose. When the door lock is not working properly, you can add a proper amount of pencil core foam and other lubricants to the key hole for lubrication.
3. When wiping the glass, do not allow the cleaning agent or water to penetrate into the gap of the glass bead to avoid deformation of the bead. Do not use excessive force when wiping the glass to avoid damage to the glass and the human body. If there is a big bump after the glass is broken, be sure to ask a professional for repair.
4. When removing the stain on the surface of the solid wood composite door (such as fingerprint), you can use a soft cloth to wipe it. Hard cloth is easy to scratch the surface. If the stain is too heavy, use a neutral detergent, toothpaste or furniture-specific cleaning agent. After decontamination, wipe it off immediately. Do not rub the corners of the solid wood composite door frequently to avoid fading and damage of the facing material at the corners. When removing dust from the wooden door, use a vacuum cleaner to remove it when not using a soft cotton cloth. In order to maintain the gloss and service life of the wooden door, it should be cleaned and dusted regularly. The surface of the wooden decoration product can be used to maintain the surface.
5, spring and winter should maintain good indoor ventilation, so that the solid wood composite door is in a normal temperature and humidity environment, to prevent the solid wood composite door due to humidity, temperature difference is too large deformation, metal fittings appear eclipse, edge banding, facing materials appear to fall off . When using electric heaters or other heating equipment in winter, keep away from solid wood composite doors to avoid deformation.
6. When painting the wall, cover the solid wood composite door to avoid the paint coating peeling off and fading the wooden door finishing material, which affects the overall appearance.
