Ultra-clear glass why can reduce the probability of steel blew?
Engineering with ultra-white glass is a boutique float glass. Ultra-clear glass can significantly reduce the tempered glass blew the probability of the reasons for the following:
①, ultra-clear glass In order to ensure product quality, the general use of ultra-white sand and fine ingredients, the use of natural gas fired from raw materials to reduce the production of nickel sulfide possibility.
② ultra-clear glass technology and quality control more common than ordinary float glass, reducing the stones, bubbles and other issues caused by the steel blew.
What is tempered glass hot dip?
What is the probability principle of hot dip to reduce the tempered glass blew?
Hot-dip treatment, also known as homogeneous treatment, commonly known as "detonated." Hot-dip treatment is the tempered glass heated to 290 ℃ ± 10 ℃, and insulation for a certain time, to promote the nickel sulfide in the tempered glass in the rapid completion of the crystal phase transformation, so that after the original use of polished glass can be artificially broken in advance of the factory Hot-dip furnace, thereby reducing the use of tempered glass after installation. The method is generally used hot air as a heating medium, foreign called "Heat Soak Test", referred to as HST, literal translation for the hot dip treatment.
Hot dip difficult. From the principle point of view, hot dip treatment is neither complicated nor difficult. But in fact to achieve this process is very difficult. Studies have shown that the specific chemical structure of nickel sulfide in glass, such as Ni7S6, NiS, NiS1.01, etc., not only the proportion of various components, and may be doped with other elements. The phase change is highly dependent on the temperature level. Studies have shown that the rate of phase change at 280 ° C is 100 times that at 250 ° C, so it is necessary to ensure that the glass in the furnace experiences the same temperature regime. Otherwise the low temperature of the glass on the one hand due to insufficient insulation time, nickel sulfide can not completely phase change, weakening the effectiveness of hot-dip. On the other hand, when the glass temperature is too high, or even lead to reverse phase transition of nickel sulfide, or stress is too high lead to excessive reduction in steel stress, causing greater hidden dangers. Both of these conditions can lead to hot dip treatment and reactive and even counterproductive.
With the relevant foreign statistics in the strict sense of the hot dip, can be reduced to the tempered glass blew probability can be reduced to 400 tons of glass per case, that blew probability can be reduced by 2 orders of magnitude. Because the strict sense can not be absolutely ruled out the steel blew, whether the glass is hot can not be detected; the same time hot-dip process time-consuming, labor, equipment and process requirements are higher, so many domestic non-standard production enterprises, often false Baptist or incomplete hot dip also affects the acceptance of hot-dip processes in the country.

Why is the back of the phone back to the glass?
July 11 BYD institutions to accept research, said most flagship mobile phone shipments next year, 15% -20%, that is, there are about 300 million mobile phones before and after the cover will use 3D glass, the total demand for 3D glass about 6 Billion, 3D glass will lead the appearance of smart phone innovation.
Perfect fit, curved screen
3D glass is currently the only better and the surface of the screen fit, and has a light, clean, anti-glare, good weather resistance and other characteristics.
High value, modeling cool
3D glass as a whole is curved, looks Ambilight, and gives a high-end viewing visual perception, with excellent touch feel and wireless charging function, beautiful and beautiful.
Materials and applications to enhance the demand, only 3D glass can do
Smart phone shell material through the plastic, metal, glass development process. At present, most of the mainstream flagship mobile phone using 2D / 2.5D glass, the back of the metal body. From the demand point of view, wireless charging, 5G and other new transmission mode is approaching, more and more complex wireless band, metal chassis shielding become a major bottleneck, backplane materials need to be replaced by non-metallic materials. Samsung S7, for example, the use of glass after the shell, the design can avoid three-stage design, and can achieve wireless charging.
From the material point of view, the current can do the phone shell of non-metallic materials are usually poly titanate (plastic, functional machine commonly used, has been eliminated), carbon fiber (cost too high) and so on. Glass because of its material, feel and processing and other characteristics, is currently the most likely non-metallic materials in the first application of the material.
From the application point of view, with the extensive application of flexible OLED, cover glass need to be made with 3D shape, and backplane glass based on grip and aesthetic requirements also need to upgrade to 3D glass.
Glass appearance has been applied in a variety of intelligent hardware, glass cover 2D to 3D upgrade, the future surface display will be used in a large number of smart phones, OLED is also a flagship mobile phone with a 3D cover a large catalyst.

High-iron glass: four secrets you do not know
Secret one: why do not look out the window does not stare the scene is not deformed?
Glass refractive index of the same train damping performance is good
High-iron car front window glass is a hyperboloid structure, the glass itself has a lot of layers, between layers and layers to maintain a high degree of consistency, this will not affect the optical effect of glass to see things not deformed. High-caliber side window glass visual effect is excellent, improve the glass in the thickness, flatness on the error, and do the glass material composition of the full homogenization, to ensure that the same refractive index, see the scene will not be deformed, and no glass Visual effects, looks comfortable, not dazzling.
The ordinary glass due to the existence of a certain optical distortion, through the glass to see the scene will produce deformation, at the same time, for high-speed movement of the scene will produce the speed of superposition, resulting in dazzling, bring a sense of dizzy. High-speed EMU train shock absorption performance is good, irregular bumps reduced, the scene shaking smaller, running very smooth, quiet, to the passengers with a slow feeling, the passengers sit there will not have a sense of dizzy.
Secret II: high-speed rail operation in the process of encounter small stones will be broken it?
The window can not be urged to withstand the speed of 355 km of aluminum bomb impact!
The current high-speed rail train running speed of 380 km / h, high speed also means that high-risk, high-speed train will be around the air compression, air resistance greatly improved, which makes the train in the process of moving through a road Brick wall, the resistance can be imagined. Therefore, in order to ensure the safety of the train, the most vulnerable windshield in the train must be hard to remind.
High - iron glass impact test
The above video is the impact test of high-iron glass, 1kg heavy aluminum bombs at a speed of 355 km per hour to the high-speed rail train on the glass, although the floor is broken glass, the window was aluminum bombs hit a pit, but the glass And was not penetrated and off the box, the window and no glass slag splash, hand hit the impact area is still very strong.
High-speed rail special attention to high-speed impact of glass material performance, which is the glass processing enterprises in the production of a threshold. Take the CRH380A EMU as an example, which requires the front windshield to withstand 1kg of aluminum bombs at a speed of 540km / h and can not be penetrated. Side window glass requires good visual performance, safety performance, energy saving performance and environmental performance.
How to prevent the glass curtain wall leakage and seepage problems
Curtain wall accessories expert analysis led to the curtain wall water seepage and leakage of the basic conditions of the three conditions: the existence of porosity; the presence of water; there is a water pressure cracks exist. So the treatment strategy: First, try to reduce the pores; Second, cover the rain, so as not to soak the gap; Third, to reduce the wetted gap at the wind pressure difference. Specific practices are as follows:
1, the design of the first consideration of the curtain wall waterproofing device design and construction, the use of isobaric principle, in the curtain wall aluminum plate is set on the pressure chamber and the special pressure into the hole, so that the pressure inside the pressure chamber through the introduction of special pressure and external pressure balance, The pressure difference to reach the indoor side of the rain, so there is no water pressure in the water there is no pressure and there is no water pressure, to prevent the use of external water pressure difference into the curtain wall, which is active waterproof measures.
2, in the curtain wall accessories on the opening of the aluminum flow to the outdoor drainage holes, through the small gap into the curtain wall of the internal collection of water outside the curtain wall, while row of glass, aluminum and aluminum buckle between the pressure chamber A small amount of water, which is one of the effective method of water control.
3, the design can also be considered in the glass curtain wall to set up the collection of pipes and drainage pipes, will penetrate the cracks into the curtain wall fittings within the water collected together, through the drainage pipe smoothly discharged to a designated indoor drainage hole, which is another Reliable water control measures.
4, the choice of high-quality structure of silicone sealant, weathering silicone sealant, wall glue, but also to strengthen the inspection to prevent expired use. Selection of high quality float glass, glass must be treated by the edge, glass size error in line with the standard requirements.
5, pay attention to control the use of sealant environment, is strictly prohibited rainy days for weathering silicone sealant construction. Structural plastic construction workshop requires clean dust, indoor temperature should not be higher than 27 ℃ (different brands of structural adhesive its performance is different from the indoor temperature requirements are slightly different), relative humidity should not be less than 50%.
6, the structure of silicone sealant, weathering silicone sealant, wall glue before injection, should first aluminum frame, glass or cracks on the dust, grease, loose and other dirt removed, Packing, surface formation, strengthen the conservation, to prevent hand touch, water red and so on.
7, according to the specification requirements, the glass curtain wall construction process should be layered anti-rain leakage performance inspection, in order to repair, the middle control curtain wall quality.

Indoor decoration should not use colored glass
Often someone in the home decoration will be the original colorless transparent flat glass windows, replaced by blue or green, brown and other colored glass, this decoration is wrong.
Colored glass is a special kind of glass, also known as endothermic glass, usually can block about 50% of the sun radiation. Such as 6 mm blue glass can only pass through 50% of the solar radiation. Brown, bronze heat-absorbing glass only through 25% of the sun. Therefore, the endothermic glass for both the need to light and heat the hot areas of the building doors and windows or outside the wall, so that both play a role in insulation and anti-glare, but also to create a beautiful cool atmosphere, but In most of the urban residential buildings can play a sterilization, disinfection, in addition to the role of taste, if these colored glass blocked out, it is worth the candle.
In addition, some households installed screens, the light transmittance of 70%, and colorless transparent ordinary glass combination, the total light transmittance of about 61%, just right, but coupled with colored heat-absorbing glass, its light transmittance only For 35%, certainly affect the indoor lighting requirements. There are also some households will be closed with colored glass insulation glass live. The balcony is the only place where the room is in direct contact with nature, and should not be closed, but not decorated with colored glass.
If long-term living in the blue-gray, brown and other low light environment, the indoor line of sight quality must decline, easy to make people physically and mentally exhausted, the health will have a negative impact. Interior decoration should use high transmittance of ordinary glass, out of the window with open and convenient shading equipment, indoor can be installed transparent or translucent and opaque window mantle. In this way, both can play a wind, shelter, heat, sound absorption and other good effects, but also fully enjoy the sun bath.
