Border profile
The base material of sliding door is generally aluminum alloy and plastic steel. Because aluminum alloy has the characteristics of light weight and high strength, it is a high-grade material for sliding door base material and has gradually replaced plastic steel products. Aluminum alloys are divided into ordinary aluminum-magnesium alloys and aluminum-titanium-magnesium alloys. Titanium has the characteristics of high strength, small specific gravity, and high toughness. Therefore, its price will be several times more expensive. In addition, advanced surface treatments include anodizing, electrophoretic carbon coating and other processes, which have higher hardness and aesthetics than simple spraying and electroplating [1] .
thickness
If glass or silver mirror is used as the door core, generally 5mm thick; if wooden board is used as the door core, 10mm thickness is the best. In order to save material costs, some manufacturers use thinner boards (8mm or even 6mm) instead. Too thin wooden boards will appear frivolous and shaky when pushed and pulled, and the stability is poor. Moreover, after a period of use, it is easy to warp and deform, and the guide rails will be stuck, resulting in unsmooth pushing and pulling, affecting normal use.
paint finish
The paint surface has undergone double-layer melting before spraying and transferring, that is, the surface is dust-removed and impurity-removed and melted, which increases the adhesion of the paint surface, and the paint surface will never fall off, while the profiles of some small manufacturers are simply melted. It does not even melt, so the paint surface is easy to fall off and the texture is not clear.
The surface of the profiles of the manufacturers of large sliding doors is processed by the company itself, and then processed with imported advanced technology. The paint surface of the product is smooth and delicate, uniform and full, and the texture is clear. The manufacturer of small sliding doors wholesales the finished colored profiles from the profile factory. The surface cannot be processed by themselves. The color is single and the color of the door type is not interchangeable. Matching, chromatic aberration, etc.
plate
The wooden boards (mainly fiberboard and particleboard) used for sliding doors are man-made boards, and the adhesives used contain formaldehyde and other harmful substances. There are many closet door manufacturers on the market, and most of their wood panels are produced in China, and even use poor and inferior panels. Many panels have excessive formaldehyde content, which emits indoors and pollutes the environment. In the cold season in the north, when doors and windows are closed, it will have a greater impact on the health of consumers.
pulley material
The pulley is the most important hardware component in the sliding door. There are three kinds of pulleys on the market: plastic pulleys, metal pulleys and fiberglass pulleys. Metal pulleys are strong, but are prone to noise when in contact with the track. Carbon fiberglass pulleys, including roller bearings, push and pull smoothly, wear-resistant and durable, box-type closed structure is effective against dust, more suitable for northern areas with heavy wind and sand, and two anti-jump devices ensure safety and reliability when sliding. The wheels of some low-grade sliding doors are made of organic plastics, which are very easy to wear and deform. Over time, they will rise and fall. The open wheel structure is easy to enter dust and wear the internal bearings. It is difficult to ensure the flexibility of pushing and pulling. , It is easy to derail when pushing and pulling, which is very unsafe.
Shake 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 slide rail. If the sliding door is of good quality, the gap between them is almost zero, so that there will be no vibration when sliding, and it will be smooth and smooth. Therefore, the tight combination of the upper pulley and the slide rail determines the smoothness of its sliding.
Bottom wheel pros and cons
Only the bottom wheel with super large bearing capacity can ensure its good sliding effect and long service life. The high-grade sliding door is made of carbon fiberglass, with balls inside, and attached with non-drying lubricating ester. The poorer pulleys are often made of engineering plastics or organic plastics, and the bearing capacity is small. Over time, it is easy to deform, affecting the push-pull effect
board style
Partition: As a partition door, most of them are relatively transparent panels, which can make the space more open, take into account the decorative effect, and match the overall room style.
Cabinet door: The materials are wood, glass, mirror and others. The height of the glass sliding door should not exceed 2.5 meters, and the mirror sliding door should not be selected for the bedroom. The plate sliding door is simple, elegant, and safe. In addition, there are also shutter series sliding doors and plate sliding doors.
stop device
The stop block is generally made of steel sheet, but if the rigidity is good, the durability will be stronger, and the rigidity is not good. In fact, metal has a fatigue period, and it is easy to deform after a long time of work, and the stop block made of copper is corrosion-resistant and can remain stable for a long time, so you can try to choose such a material
