>>>Recommendation: Room door knowledge and wood door color choice
Home security "door" face work to do three
The importance of interior doors is not a matter of opinion. However, from the material point of view, there are also solid wood doors, steel doors, solid wood composite doors, molded wooden doors, etc., which have their own advantages and disadvantages. According to industry insiders, these doors can also be reasonably purchased according to their indoor use and their own economic conditions.
Solid wood door key technology
The solid wood door is also called the original wood door, and is made of natural wood as the core of the door. After being dried, it is processed scientifically by blanking, planing, slitting, drilling, high-speed milling and other processes. Solid wood doors are made of high quality materials such as cherry, walnut, teak, sabilly, rosewood, etc. They have good sound absorption and sound insulation.
The natural wood grain texture and color of the solid wood door is undoubtedly the best choice for the family who admire the style of return to nature. Solid wood doors reveal a kind of warmth since ancient times. They not only look beautiful, and are exquisitely carved, but also have a variety of styles. The market price ranges from 1,500 to 3,000 yuan. Generally high-grade solid wood doors do well in the dewatering process. The relative moisture content is about 8%. After the doors are formed, the doors are not easy to deform and crack, and the use time is longer.
However, the solid wood door market is quite confusing and the surface material of the wooden door is difficult for consumers to distinguish if there are no professional sales personnel. Industry insiders told reporters that due to the use of wood processing, the flat surface area is large, and there are few fixed points, so it is one of the most likely causes of deformation and cracking. The deformed wooden doors will directly affect the sound insulation, airtightness and aesthetics of the house. Paint is used as a post-manufacturing process for the set of wooden door factories. Its advantages and disadvantages directly affect the final use effect. At the same time, the paint cost is also one of the largest parts of the wooden door. If poor paint is used, the harmful components contained in the paint may also have a certain impact on human health. In addition, coupled with the overall processing technology or not, have a direct impact on the texture, feel, moisture, environmental protection, durability, resistance to yellowing and other issues.
Countermeasures: Insiders said that when you buy a door, besides buying more than three major brands, weight is a method of identification. In order to cover up the material, some businesses will seal all around the door, including the bottom, so that people can not distinguish from the appearance, while the regular business around the door and the bottom is not painted. In addition, the price of ordinary solid wood slat doors for purchase and transportation costs at least more than 1,000 yuan. If they claim to sell solid wood doors for seven or eight hundred yuan, they must have quality problems.
Recommendation: Solid wood doors have high requirements for door frame sets due to their heavy weight, and some also require installation of springs and other devices. They are not suitable for use in home renovations. They can only be used as gates, or the wooden door can be selected as the master bedroom of a villa.
Steel wood interior door selection is a bit difficult
Steel-wood interior doors are interior doors that extend from security doors. The process is similar to that of anti-theft doors. The main frame is made of wood. The imported high-quality steel plate is combined with the wood inner rib embossing, and some surfaces are covered with PVC material. Environmentally friendly materials are subjected to polyurethane foaming and honeycomb filling. The appearance is beautiful, sturdy, environmentally friendly, easy to clean, and the price is relatively low.
Steel wood interior doors have the advantages of moisture-proof, insect-proof, no deformation, no cracking, firmness and durability, and good insulation performance. It can be freely used with wooden frames, aluminum frames, steel frames, and steel frames, and is suitable for walls of different thicknesses. It is easy to install, has a variety of colors, and is individually designed to meet the needs of different customers. However, steel doors are scarred and it is difficult to repair them once they are scratched. This kind of door is easy to form small nests, because the surface is only a thin layer of steel, but it may rust after a long time. In addition, the steel plate is a hard medium, which often has surface unevenness or is difficult to recover due to inadvertent collision.
At this exhibition of building materials, the reporter saw that the steel doors have been accurately matched with stainless steel hinges and stainless steel screws to ensure that the doors are not easily deformed.
Countermeasures: Steel doors are painted on the surface, but also coated with imitation paint and wood. High strength, no deformation, strong and durable, outstanding cost performance. However, when you buy it, you have to carefully screen it, and you have a lot of inferior goods.
Recommendation: High security and strong privacy, but whether it is a surface paint or a film, there will be hidden concerns about the rust of the surface layer of shed metal. How to look at the surface wood is false, uncomfortable, and easy to aging, can not easily make up after the scratch paint.
The future trend of solid wood composite doors
The door core of the solid wood composite door is mostly made of pine, fir or imported filling materials, and is laminated with a density board and solid wood veneer, made by high temperature hot pressing, and sealed with solid wood lines. General high-level solid wood composite door, its door core is mostly white pine, the surface is solid wood veneer. Due to the small density and light weight of the white pine, and the easier control of the moisture content, the weight of the finished door is lighter, and it is also less prone to 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 a solid wood door.
Because of the diverse shapes and styles of solid wood composite doors, or the exquisite European-style carvings, or the Chinese classic colored mosaics, or the modern fashion, the doors of different decorative styles give consumers a wide selection space, which is also called a solid wood model door. High-grade solid wood composite doors not only have the characteristics of smooth touch, soft color, but also very environmentally friendly, durable. It maintains the effect and perception of solid wood, but it is more stable than the quality of solid wood doors and the price is more economical than solid wood doors.
Because of the inherent internal stress of wood, solid wood doors can easily bring about problems such as cracking and deformation. Solid wood composite doors make wood properties more stable through drying, finger-jointing, cooking, planing, hot pressing, and compounding. The effect is more beautiful.
Compared to the pure solid wood door expensive cost, the price of solid wood composite doors is generally around 1200~2300 yuan. Such as high-grade rosewood doors, about 2300 yuan a fan; in the high-end walnut, cherry, Sapele and other wooden doors, the price is less than 2,000 yuan a fan.
However, the reporter walked around the market and found that many economical solid wood composite doors, in order to cut corners and materials, would be filled with lumber at the places where the wooden doors are close to the door locks and the hinges, and inferior wood was used in other places. Because the installation of the door lock needs to be digged, consumers can see the material inside the wooden door, so that the configuration can bypass the sea.
There are also wooden stickers on the surface of the door that are affixed with veneer wood. The texture of the grained paper surface is very similar to the texture of the real wood grain. The average consumer does not discern it at all. However, the prices of the two are quite different. The same area of ​​woodgrain paper is three or four hundred dollars cheaper than wood veneer, and is afraid of water and is easily damaged.
Countermeasures: According to professionals, the grainy paper lines are relatively dull and even, and several wooden doors with the same stickers are lined together. The lines will show consistency. If you encounter a groove, the paper will be more rounded and docile; and the veneer will have knots. The phenomenon of blemishes, spots, black lines, etc., when several doors are put together, the lines are definitely inconsistent. If the veneers meet the grooves, they are neither round nor docile.
Suggestion: The most important thing is to consider the privacy of the bedroom door and create a warm atmosphere. Therefore, more light-transmitting weak and solid doors are used. The solid wood composite door is a good choice, and the price is moderate, to the professional large formal The building materials market chooses some big brands of products to ensure quality. Bedroom doors, rooms and children's rooms can be tailored according to the style of the decoration. General apartment, a few space doors to choose the same style appearance is more secure.
Molded wooden door easy pollution source
Molded wooden doors are favored by middle-income families because they are more affordable and safer than solid wood doors. The molded wood door is mechanically repressed by two high density fiber molded door skins with modeling and simulated wood grain. Since the door panel is hollow, the natural sound insulation effect is worse than that of a solid wood door, and it cannot be wet.
Molded wooden doors are veneered and brushed with "clear varnish" wood veneer board to maintain the decorative effect of natural wood texture. At the same time, it can also be used for panel mosaic, which is beautiful, lively and economical. Molded door also has the characteristics of moisture-proof, small expansion coefficient and anti-deformation. After a period of use, there will be no surface cracking and oxidative discoloration.
General composite molded wood doors are delivered with a neutral white primer. Consumers can go home and paint on white neutral primers to suit individual preferences. This meets the individual needs of consumers. Compared to hand-made solid wood doors, molded doors use mechanized production, so their cost is also low. At present, the molded wood doors in the market are mostly between 380 and 500 yuan, and the cheapest is only about 200 yuan. Because the construction process of the molded door is relatively simple, it does not seem that the solid wood door is thick and beautiful.
Countermeasures: The molded wooden doors with poor quality have a long time and are easily affected by humidity, temperature, and air, causing the surface to deform. Some of the doors on the market that do slot milling are also known as using melamine finishes. In fact, they are all made of plastic, because melamine cannot press out the concave and convex shapes at all.
Identify the quality of molded wood doors mainly from two aspects, one is the surface flatness, and the other is the door shut. When looking at the side light, if you find that the flatness of the door panel is poor, the door panel is not uniform in reflection. If you look at plastic material, you should not buy it.
Suggestion: Molded wooden doors are mainly used in balconies, storage rooms and other places that are not frequently opened. However, one problem is very serious, that is, it will release harmful gases in itself and may become a source of indoor air pollution.
