Why should we pay attention to the surface treatment of slide rail?

Choosing the right metal surface treatment process is not just for color and matching home. It is also a complex process, and different choices will affect the function and life. Most of the corrosion of metal materials occurs in the atmospheric environment, which contains oxygen, humidity, temperature changes and pollutants and other corrosion components and corrosion factors. Salt spray corrosion is a common and powerful destructive atmospheric corrosion. Salt spray on the corrosion of metal materials, mainly conductive salt solution into the metal internal electrochemical reaction, the formation of "low potential metal-electrolyte solution a high potential impurities" micro battery system, electron transfer, as the anode of the metal dissolved, the formation of new compounds that corrosion. Salt spray corrosion damage process plays a major role in the chloride ion, it has a strong penetration ability, easy to penetrate the metal oxide layer into the metal, destroy the metal passive state; at the same time, the chloride ion has a very small hydration energy, easy to be adsorbed on the metal surface, replace the protection of metal oxide layer of oxygen, so that the metal is damaged. The 2008 China Olympic Games is held, the world's attention to Beijing, and the Bird's Nest as the global host of the 2008 China Olympic Games, its surface treatment is how to do it? The bird's nest anti-corrosion technology bird's nest "shape structure is mainly composed of a huge portal steel frame, a total of 24 truss columns. The top of the stadium building is saddle-shaped, with a long axis of 332.3 meters, a short axis of 296.4 meters, a high point height of 68.5 meters, and a low point height of 42.8 meters. The anti-corrosion project of "Bird's Nest" steel structure is one of the more anti-corrosion coating procedures for domestic building steel structures. As the world's largest single steel structure project, the "Bird's Nest" steel structure coating area of 284000 square meters. The Bird's Nest will wear a 6-layer antiseptic mask that will last for more than 25 years. There are 6 manufacturers in the country to produce steel products required for the "Bird's Nest. In the country of origin, these steel products will be painted with primer and sealer, which are yellow and red respectively, which are the first two anti-corrosion masks. Then, all the steel products are concentrated on the construction site and coated with intermediate paint and fluorocarbon color paint, which is the third and fourth processes. From the fourth lane, the color of the paint becomes gray. After that, the shelving and assembly of the steel structure are started, and the top coat and finish coat are applied in turn. There are many different application methods and application environments for slide rails. In the process of producing slide rails, we need to protect our slide rails from various factors like a bird's nest. This is why we integrate the rail surface treatment scheme to suit its different application environments. A surface treatment is a protective chemical coating that helps the metal surface resist corrosion. In addition to stainless steel, steel is even susceptible to slight moisture. Therefore, proper anti-rust treatment can extend the service life of drawer slides for decades. What ingredients are added to the slide surface treatment? Let's take a look. 1. Blue and white zinc plating 2. Black electrophoretic paint 3. White baking paint Galvanizing is one of the three common surface treatment agents:. It uses a zinc-based coating made of clear or black chromate coating, the standard coating, which can resist moderate corrosion. It is suitable for indoor environments, such as office and home cabinets. In contrast, black electrophoresis, which is often used, can provide several times the corrosion resistance of the galvanized layer, and tends to be used on dark cabinets. White paint has stronger corrosion resistance and can be used in kitchen furniture and appliances-the first is usually white appearance. These colors help the slide to blend in with its application environment. Our weather-resistant slide rails add an additional coating on the basis of standard galvanized, which can protect the slide rails from outdoor environmental factors.

Characteristics and Usage of Rebound Slide

Features: 1. Rebound: new design scheme can be realized without handle. 2. Three sections: can be pulled out completely. 3. Bottom support: hidden installation, which can leave a small installation distance, and the hardware is not exposed. The rebound slide can completely pull out the inner rail. The installed slide rail is difficult to see from the outside, so it will not affect the appearance of the cabinet. Simply press the front panel to open the drawer. Therefore, there is no need for a handle or gripper, and the cabinet looks flat and tidy. The amount of pressing is small, even if you hold items in both hands, you can easily open the drawer by slightly pressing the front plate with your elbow. The drawers can be easily removed. The press opening device is built into the slide rail, which is the same as the previous slide rail, and the installation is simple and convenient. Note: Do not close the drawer violently or impact it violently. Otherwise, the drawer may be accidentally damaged. Do not slam open or pull out the drawer when closed. Otherwise, damage to the rails can occur. Installation: First of all, there must be a product drawing of the steel ball slide rail. According to the slide rail drawing, the clearance required to install both sides of the slide rail is given. Generally, the left and right installation clearance of the 45m wide rebound slide rail is about 13.3mm. It should be noted that the installation of the rebound steel ball slide rail needs to reserve space for the drawer to touch the rebound. 2. Determine the screw hole position according to the fixed rail (outer rail) given in the manufacturer's drawings (there are all kinds of slide rails in the market, and basically the steel ball slide rail hole positions produced by each manufacturer are different, so it should be processed according to the drawings of the slide rail manufacturer you purchased). According to actual requirements, those with less personal consumption can be punched manually, and those with a large amount of furniture can be punched mechanically. The scribing method can also be used for positioning. 3. After the drilling is completed, pick up the slide rail and pull out the movable rail (inner rail) with hand, separate it from the fixed rail (outer rail), lock the two fixed rails (outer rails) to the side plates on both sides of the cabinet body with screws according to the hole positions, and then lock the two movable rails to the side plates on both sides of the drawer according to the hole positions. 4. After completing the above steps, then align the ends of the movable rails (inner rails) on both sides of the drawer side panel with the ends of the fixed rails (outer rails), and then gently push them inward to clip the movable rails to complete the installation of the rebound steel ball slide rails.

Why can stainless steel slide rail be adsorbed by magnet?

Some friends in the purchase of stainless steel slide rail, will use a magnet to attract a suction, think that stainless steel material, by the magnet adsorption is false, not by the magnet adsorption is true, in fact, this is a very wrong judgment. Generally speaking, stainless steel is magnetic and non-magnetic, austenitic stainless steel is weakly magnetic or non-magnetic, such as 201,304, martensite or ferrite is magnetic, 430,310, etc. Due to improper heat treatment during smelting, there is a small amount of martensite or ferrite in austenitic stainless steel, so there will be micro-magnetism in stainless steel. The small accessories inside the slide rail produced by the general slide rail hardware company are made of stainless steel, and the manufacturer has not done demagnetization treatment, so there will also be the phenomenon that magnets can be adsorbed. It is not widely circulated that stainless steel can be adsorbed is fake, but cannot be adsorbed is real.

Why does stainless steel slide rail rust?

Stainless steel slides are generally made of 304 stainless steel or 201 stainless steel. Stainless steel has the characteristics of corrosion resistance, oxidation resistance, easy processing, high hardness, and good ductility. It is widely used in all walks of life, but stainless steel will rust over time. This is not a quality problem, but caused by the use environment! So why does the stainless steel slide still rust? This is because stainless steel can resist part of acid, alkali and salt corrosion in dry air, and can prevent rust to the general humidity of the air. However, it is easy to rust in coastal cities where the air contains a lot of salt spray, because stainless steel is an extremely thin, strong, fine and stable chromium-rich oxide film (protective film) formed on its surface to prevent the continuous infiltration and oxidation of oxygen atoms and obtain the ability to resist rust. Once there is some reason, this film has been constantly destroyed, the oxygen atoms in the air or liquid will continue to penetrate or the iron atoms in the metal will continue to separate out, the formation of loose iron oxide, the metal surface will be constantly corroded. There are many forms of damage to this surface film. The following are common in daily life: 1. The surface of stainless steel contains dust containing other metal elements or attachments of heterogeneous metal particles. In humid air, the attachments The condensed water between the object and the stainless steel connects the two into a micro-battery, causing an electrochemical reaction, and the protective film is damaged, which is called electrochemical corrosion. 2. Stainless steel surface adhesion of organic juice (such as vegetables, noodles soup, phlegm, etc.), in the case of water and oxygen, constitute organic acid, long time organic acid on the metal surface corrosion. 3. Stainless steel surface adhesion contains acid, alkali, salt substances (such as the decoration of the wall of alkaline water, lime water splash), causing local corrosion. 4. In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), the condensed water forms sulfuric acid, nitric acid and acetic acid liquid points, causing chemical corrosion.

Comparison of Damping Slide and Ordinary Slide

In recent years, China's national strength is growing day by day, the people's life is getting better and better, and the pursuit of products is getting higher and higher. The slide rails in furniture products are now beginning to pursue a better experience. Damping slide rail The damping slide rail slows down the speed, reduces the impact force, and has a gentle effect when it is closed. Even if you push the drawer hard, it will gently close, ensuring perfect and quiet movement. For home life has played a embellishment of life. Damping slide principle: Through the hydraulic cylinder, there is oil in it. When the slide is facing extreme closure, it forms resistance and has a buffering effect. There is also air pressure. The principle of this air pressure is similar to hydraulic pressure, but it is oil. Changed to air. Damping slide rail structure: fixed rail, middle rail, movable rail, ball, clutch and buffer. The buffer is installed in the fixed rail; the buffer includes a piston rod, a shell, and a piston. The piston is provided with a through hole and Hole, when the piston rod drives the piston to move, the liquid can flow from one side to the other through the through hole, thereby playing a buffering and damping effect. Ordinary slide rail ordinary slide rail has no hydraulic cylinder or cylinder compared with damping slide rail. When purchasing, attention should be paid to quality and fullness of steel balls. During installation, horizontal installation should be adjusted. One side is high and the other side is low. During use, one side is not allowed to be opened and closed frequently. Some businesses exaggerate the data when publicizing the slide rail, saying that the life of the slide rail is very long, more than 100000 times (100000 times), but in fact, the life standard of a pair of slide rail in the industry is about 50000 times (50000 times).

Is it better to use three ordinary slides or damping slides for drawer slides?

Is it better to use three ordinary slides or damping slides for drawer slides? Answer: Generally speaking, ordinary damping slide rails are very popular as products now. If you want to have a good use experience for the cabinet table in your home, you recommend use damping slide rails. However, if you have a deep cabinet in your home, you can pull out the damping slide rails, and the rebound time will be longer. It feels "a little slow" to use, so you can recommend ordinary slide rails. Damping slide features: excellent: reduce friction, so that the drawer closed silently, protect the furniture. Lack: the installation process is relatively accurate, relatively ordinary steel ball guide rail easy to break. In addition, for integrated stoves, the slide rail of the dishwasher cannot be used because of the chemical composition inside the damping slide rail.

Basic Terms of Slide

At present, the sliding rails on the market include roller sliding rails, steel ball sliding rails, wear-resistant nylon sliding rails, gear sliding rails, etc. regular steel ball sliding rails are composed of steel balls, inner rails, outer rails, three-section rails and middle rails. Classification of slide rail: load classification: light, medium and heavy section classification: 2-section and 3-section application classification: industrial application/household appliance application/furniture application/medical application structure of slide rail: steel balls, beads, beads, plastic parts, inner rails, outer rails and middle rails form double-layer and single-layer differential strokes: I .e. 2/3 strokes of the length that the slide rail can be drawn from the cabinet: the pull-out length is 2/3 of the total length of the slide rail. For example, the full stroke of the 2701 model means that the pull-out length is equal to the total length of the slide rail. For example, the 4501 overstroke means that the pull-out length exceeds the total length of the slide rail. For example, the two-way stroke means that the pull-out direction of the slide rail is two directions. For example, the installation gap of 2704B200: the load test of the slide rail is based on a pair of sliding tests with a length of 400mm. There is no problem, and the slide rail above 400mm will be lowered. Split method: most of the slide rails are detachable, and some customized slide rails are not detachable

The thickness of slide material directly affects the quality of slide rail

In the slide rails in the hardware industry, the material thickness of the three-section slide rails commonly used in ordinary drawers is generally 1.0*1.0*1.2mm, and the higher-grade slide rail is 1.2*1.2*1.4mm. This is the thickness of the standard three-section slide rail, and the thickness of the heavy-duty three-section slide rail will be thicker. However, some slide rail manufacturers, in order to save the cost of the slide rail, have produced 0.8mm, 0.7mm or even 0.6mm material thickness of the slide rail. When the thickness of the slide rail is thinner, its load-bearing capacity will be lower. The thickness of the material will not only affect the load-bearing capacity of the slide rail, but also directly affect the quality of the slide rail. If the material is too thin, the overall effect and quality of the slide rail will be reduced. So in the choice of hardware slide rail, do not in order to save a little bit of cost and let the quality of the whole product is affected, because of small losses!
