Chemically strengthened glass promotes the popularity of smartphone cover glass
Beijing time July 01 news, China touch screen network news, chemically strengthened glass refers to glass whose strength has been increased through chemical strengthening treatment. It is known because the US Apple "iPhone" and "iPad" use Corning's chemically strengthened glass "Gorilla Glass". In the past, the surface covers of older mobile phones were mostly made of resin. Smartphones and tablet computers, on the other hand, mainly use chemically strengthened glass, which is not easily scratched on the surface and has high strength, in order to facilitate users to operate the touch screen. Among them, the market share of Gorilla Glass is far ahead, and the second place is "Dragontrail" of Asahi Glass. Chemically strengthened glass usually refers to aluminosilicate glass that has been chemically strengthened. While soda-lime glass used in windows and the like can also be chemically strengthened, chemically strengthened aluminosilicate glass is superior in strength. Aluminosilicate glass contains sodium ions. By immersing the glass in a high temperature potassium nitrate (KNO3) solution, the sodium ions on the surface of the glass are replaced by potassium ions (ion exchange). Potassium ions have a larger diameter than sodium ions, so through ion exchange, the surface area of the glass increases. But in reality, the volume does not change, so a "compressive stress" occurs. This is how increasing strength through chemical strengthening works. Recently, "OGS (one glass solution)" has attracted attention as a method to reduce the number of glass substrates used. OGS specifically refers to the integration of the touch panel on the glass cover. However, chemically strengthened glass is less compatible with OGS. Chemically strengthened glass is not easy to cut, so it was originally made by the glass cover manufacturer after cutting the final shape, and then chemically strengthened. To use OGS to reduce costs, the best way is to combine the patterns of multiple touch panels to improve them, and then cut them. Therefore, in order to be able to use the OGS method, glass manufacturers provide large-sized glass that is easier to cut and chemically strengthened.

Glass can be seen everywhere in our life, it can be said to be all over the world. We all know that glass is a kind of thing that is easily broken. How much do you know about tempered glass? What is the difference between the two types of glass? Tempered glass definition: Tempered glass, also known as tempered glass, is actually a kind of prestressed glass. It is made by heating ordinary glass electrically in a tempering furnace and rapidly cooling it with a fan. It is commonly used as flat tempered glass. Tempered glass application areas: Tempered glass is widely used in furniture, electronic appliances, construction, decoration, bathrooms, cars, escalators, and other places that require special safety and have drastic changes in temperature, and can be used as a raw material for insulating glass and laminated glass. piece. Brief Description of Tempered Glass: Tempered glass is a physical or chemical method to form a compressive stress layer on the surface of the glass. The glass itself has a high compressive strength and will not cause damage. When the glass is subjected to external force, this pressure layer can offset some tensile stress and avoid glass breakage. Although the tempered glass is in a state of large tensile stress, the interior of the glass has no defects and will not cause damage. , and then arrive at the intention of increasing the strength of the glass. Tempered glass classification: According to the original glass used, it can be made into general tempered glass, endothermic tempered glass, color tempered glass, tempered insulating glass, etc. Tempered glass market prospects: Most of the tempered glass on the market is used in the decoration industry, and its products are mainly bonded to the glass surface through a reinforced film, so that it can strengthen the explosion-proof effect. If the glass is damaged due to external force, the glass fragments will be tightly adhered to the high-strength and high-strength polymer film, and will not fall off, and the safety function is high. There are countless types of reinforced film. Compared with the typical colored reinforced film, commonly known as "photo film", this product uses ink modification skills, so that the color painting is reflected on the film, and then reaches the role of stained glass. Eco-friendly features are low. There are also color films made of printing composite technology. There are many such products on the market, and the types of these products vary from manufacturer to manufacturer. The typical "Diwei film", "Meidi color film", "Dia film" etc., its product characteristics are better than "photo film", the substrate is mostly made of environmentally friendly PET, and the environmental protection and safety functions are ideal. Currently, this product is mostly used in the production of tempered glass.

5 methods of how to detect high temperature tempered glass
High temperature resistant tempered glass is a common auxiliary tempered glass product for industrial boilers and industrial furnaces. There are five main inspection methods: 1. Scale inspection: use a ruler or tape measure with a minimum scale of 1mm to measure the diameter of the glass, Length, width and thickness. When it comes to high precision, it can be measured with a micrometer or an instrument of equal precision, with millimeters (mm) as the unit and accurate to two decimal places. 2. Anti-shock function inspection: including wind pressure resistance function inspection and anti-heavy object falling ball function inspection. 3. Bending inspection: put the high temperature resistant tempered glass upright, and place the ruler horizontally against the surface of the glass for measurement. The bow is expressed as a percentage of the ratio of the height of the arc to the length of the chord. Waveform, expressed as a percentage of the ratio of the trough-to-peak height to the peak-to-peak (or trough-to-trough interval). 4. Fragment condition inspection: place the high temperature resistant tempered glass sample on another sample of the same shape and size, bond the two samples with photosensitive paper, and use scotch tape to stick around the periphery. On the longest side and base line of the sample at a distance of about 20mm around the periphery, impact with a small hammer or punch with a tip curvature radius of 0.2mm ± 0.05mm to break the sample. 5. Appearance inspection: take the product as the real object, and inspect it with the naked eye under better natural light or scattered light conditions. Today's tempered glass not only integrates into our life, but also adds a color to our home. The emergence of tempered glass has deeply driven the development of the glass industry. After many of our homes have such a home, we can be safer and more assured.
