1, border profile
The sliding door base material is generally aluminum alloy and plastic steel. Due to its light weight and high strength, aluminum alloys are high-grade materials for sliding door substrates and have gradually replaced plastic steel products. Aluminum alloy is divided into ordinary aluminum magnesium alloy and aluminum titanium magnesium alloy, titanium metal has high strength, small specific gravity, high toughness and other characteristics, therefore, its price will be expensive several times. In addition, advanced surface treatments include anodization, electrophoretic coating, and carbon coating. These processes have higher hardness and aesthetics than simple spraying and plating.
If a glass or silver mirror is used as the core of the door, it is generally 5mm thick; if the wooden door core is used, the thickness of 10mm is the best. Some manufacturers use thinner boards (8mm or even 6mm) to save material costs. Too thin planks, push-pull up appears to be frivolous, shaking, poor stability, and after using for a period of time, it is easy to warp deformation, card guide rails, resulting in push and pull is not smooth, affecting the normal use.
The paint surface has undergone double-layering in the spray transfer process, ie, dust removal and impurity removal on the surface, which increases the adhesion of the paint surface and the paint surface will never come off. However, some small manufacturers' profiles are simply fired. Even without melting, the paint is easy to fall off and the texture is not clear.
The surface of the profiles of large sliding door manufacturers is handled by the company itself and then processed using imported advanced technology. The product's paint surface is smooth, smooth, even and full, and has a clear texture. Manufacturers of small-sized sliding doors wholesale the finished colored material from the profile plant. The surface cannot be processed by itself. The color is single and the door color is not interchangeable. If the profile is scratched during transportation or installation, the color of the original door is not Matching, color differences and other issues.
The planks used to make sliding doors (mainly fiberboard and chipboard) are man-made boards, and the adhesive used contains harmful substances such as formaldehyde. Many of the closet door manufacturers on the market, most of their wood production in the country, and even the use of poor plate, a lot of formaldehyde content of the plate exceeded the standard, distributed indoor, polluting the environment. In the cold season in the north, when the doors and windows are closed, the health of consumers will be more affected.
5, pulley material
The pulley is the most important hardware component in the sliding door. The material of the pulley on the market is plastic pulley, metal pulley and glass fiber pulley. Metal pulleys are strong but tend to produce noise when in contact with rails. Carbon fiberglass pulleys, including roller bearings, sliding smooth, durable wear, box-type closed structure is effective in dust, more suitable for large northern sand areas, two anti-jump devices to ensure safe and reliable slide. The wheels of some low-grade sliding doors, made of organic plastic, are easy to wear and deform. The time of long-time push-pull is high and low, the open-wheel structure is easy to enter the dust and wear the internal bearings, it is difficult to guarantee the push-pull flexibility, and there is no anti-jump device. It is easy to derail when pushing and pulling. It is not safe.
Swing the sliding door in the vertical direction of the slide rail, the smaller the degree of shaking, the better the stability. When shaking, pay attention to the upper pulley and the upper rail. If the sliding door is of good quality, the gap between them is almost zero. In this way, there will be no vibration and smoothness and smoothness. Therefore, the tight combination of the upper pulley and the slide rail determines the smoothness of its sliding.
6, the advantages and disadvantages of the bottom wheel
Only the bottom wheels with large bearing weight can guarantee its good sliding effect and long service life. The high-grade sliding door is made of carbon glass fiber, with inner ball, and with lubricating grease. The poor pulleys are often made of engineering plastics or organic plastics. The load-bearing force is small, and it may not cause serious problems when it is used. A long time is easy to deform, affecting the push and pull effect
7, board style
Partition: As the partition door, most of the more transparent board surface can make the space more open, taking into account the decorative effect, and match the overall living room style.
Doors: There are planks, glass, mirrors and other materials. The height of glass sliding doors should not exceed 2.5 meters. The bedroom should not choose mirror sliding doors. The sliding door of the plate is simple and generous, and the safety is good. In addition, there are shutter sliding doors and sliding panels.
8, stop device
The stop block is generally made of steel sheet, but the durability of the steel is good and the steel is not good. After a long time collision, it will shift, and the sliding door cannot be stopped in place. In fact, metal has a fatigue period. After a long time of work, it is easily deformed. The stop block made of copper is corrosion-resistant and stable for a long time. Therefore, it is possible to select the material as much as possible.
