These two kinds of equipment can be used in glass edging, one is glass edging machine, the other is edge pulling machine. These two kinds of equipment can be used for glass edging, but the effect is different.The difference between glass grinding and pulling edge shows that one is grinding and the other is pulling. Grinding edge is better understood than drawing edge, while the edge drawing is mainly in the process of glass production.Differences in Glass Edging Machine and Edge Pulling MachineGlass edge grindingGlass edge grinding generally uses glass edge grinding machine to grind the edge of the glass, so that the sharp edge becomes smooth and does not hurt people. At the same time, special-shaped glass edge grinding machine can be used to reprocess the shape of the glass. ENKONGS is mainly committed to the R & D and production of glass edging machine.Glass edge pullingGlass edge pulling is generally used in the production process of glass, which is mostly used in the production and molding of float glass.Working principle of glass edge drawingTwo kinds of liquid with different specific gravity, the one with small specific gravity floats on the top, and the one with large specific gravity floats on the bottom. The float glass is formed in the tin bath, that is, the molten glass continuously flows into the tin bath from the overflow channel and the launder, spreads out on the tin surface and drifts forward under the traction of the driving roller. Under a certain temperature, it is flattened and thinned by surface tension and gravity. After cooling, the glass is lifted up by the transition roller platform, left the tin bath and entered the annealing furnace. Finally, the glass is crosscut, inspected and packed. The float glass produced by special technology has the characteristics of good quality, many varieties, high output and long operation cycle.Float glass can be roughly divided into two types:Colorless transparent float glass: transparent float glass is a glass liquid which melts evenly through the channel and enters into the tin bath. Due to its own gravity and surface tension, the glass liquid is naturally flattened on the surface of molten tin liquid and becomes a glass belt, which is made by external force pulling and temperature adjustment.Glass edge drawing characteristics:Smooth surface, no ripple, good perspective.The specification can be elastic fit to reduce the slice loss.It can provide materials for manufacturing various processing levels.The difference between glass grinding machine and glass pulling:Different uses: glass edge grinding machine is glass reprocessing, glass edge pulling is a production process.Different time: glass edge grinding machine is used after the completion of glass production, glass edge pulling is used in the glass production process.Different machines: glass edging machine is used for grinding edge, glass pulling machine is used for drawing edge.Edging machine can be divided into: glass linear edging machine, glass linear beveling machine, special-shaped edging machine, crystal steel door glass edging machine, cabinet glass edging machine, etc.Edge pulling machine is divided into: glass edge pulling machine, glass edge rolling machine, etc.Different products: edge grinding is based on the inherent glass products, while edge drawing is to directly produce a certain kind of glass machine products.

Switchable glass is a new type of special photoelectric glass product with sandwich structure, which is composed of liquid crystal film and two layers of glass, glued by high temperature and high pressure. The user controls the transparency and opacity of the glass by controlling whether the current is on or off. The glass itself not only has the characteristics of all safety glass, but also has the privacy protection function of controlling whether the glass is transparent or not. Due to the characteristics of the liquid crystal film interlayer, the switchable glass can also be used as a projection screen to replace the ordinary curtain to present high-definition images on the glass.Switchable glass and its daily maintenanceSwitchable glass was invented and patented by researchers at Kent State University in the late 1980s. In China, people used to call switchable glass as intelligent electronic switchable glass, intelligent glass, liquid crystal glass, electronic control glass, color changing glass, PDLC glass, smart glass, magic glass, etc. Intelligent electronic control switchable glass began to enter the domestic market in 2003. Due to the high price and the lack of knowledge, it developed slowly in China in the next decade. With the sustained and rapid growth of the national economy and the rapid development of the domestic building materials market, the intelligent electronic control switchable glass has gradually been accepted by the construction and design industry and started to be applied on a large scale, With the further reduction of cost and market price, switchable glass has entered the application field of home decoration. I believe that this practical high-tech product will enter thousands of households in the near future.What are the basic maintenance methods of switchable glass? The following is for reference.1.Do not collide the glass surface with force at ordinary times. In order to prevent the glass surface from scratching, lay a tablecloth. When putting things on the switchable glass furniture, you should handle them with care and avoid collision.2.In daily cleaning, wipe it with wet towel or newspaper. In case of stains, wipe it with a towel dipped in a little beer or warm vinegar. In addition, use the glass cleaning agent currently on the market. Avoid cleaning with strong acid-base solution. In winter, the surface of the glass is easy to frost. It can be cleaned with cloth soaked in salt or wine.3.Using a cloth sprayed with detergent can also make the glass stained with oil to be clean. First of all, spray the special cleaning agent for the switchable glass, and then stick the preservative film to soften the solidified oil. After 15 minutes, tear off the preservative film, and then wipe it with a wet cloth. If you want to keep the switchable glass bright and clean, you must always clean it. If there is any writing on the glass, you can rub it with rubber soaked in water, and then wipe it with wet cloth. If there is paint on the glass, you can scrub it with cotton dipped in hot vinegar. If you wipe the glass with clean dry cloth dipped in alcohol, you can make it as bright as crystal.4.Keep away from kitchens, such as stoves. In addition, avoid wetting. Stoves should be isolated from acid, alkali and other chemical reagents to prevent erosion and deterioration.5.Switchable glass furniture placed in a more fixed place, do not randomly move back and forth, to place objects smoothly, heavy objects should be placed at the bottom of the glass furniture, to prevent furniture center of gravity instability caused by overturning.6.Once the patterned switchable glass is dirty, you can use a toothbrush dipped with detergent to wipe it in circles along the pattern. So the glass is clean and bright.7.Glass serious scratches can not be repaired, if it is a very slight scratch can be repaired with the repair polishing wheel.
