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.
The world's photo-voltaic installed demand has increased significantly this year, and the prices of upstream and downstream products of the industry have been rising. With such a good market, the price of photo-voltaic glass has been exposed that suddenly dropped by about 30%. Is the price reduction true? What is the impact on PV module enterprises and the whole industry?Why is the price of photo-voltaic glass reduced by 30%?Recently, news of price reduction of photo-voltaic glass came out intensively in photo-voltaic industry. According to media reports, the price of 3.2mm coated photo-voltaic glass is expected to be reduced from 40RMB per square meter to less than 30 RMB per square meter. It is estimated that the price will drop by about 30%. Some organizations confirmed the news. The information analyst Wang Shuai from Zhuo Chuang also told reporters that the new price of photo-voltaic glass in April has dropped. Wang Shuai said: "in April, the new unit price: 3.2mm coating price is 28 RMB per square meter, down 30% month on month and 3.45% year on year. At present, the new orders of photo-voltaic glass machinery manufacturers are insufficient and the inventory growth is obvious. Due to the increase in inventory of some glass manufacturers, there is still room for bargaining. "It is predicted by domestic and foreign organizations that the new installed capacity of photo-voltaic in the world this year will be as high as 180gw, a year-on-year increase of 27%. The new installed capacity of photo-voltaic in China will reach 55-65gw, a significant increase compared with last year. In this context, the price of photo-voltaic glass in the upstream of the industry is cut by 30%, and there is still room for negotiation, which obviously deviates from the heat of the whole photo-voltaic market. What is the reason? According to Wang Shuai's analysis, the main reason is that the downstream PV module enterprises are squeezed by the high cost of the upstream and have reduced production. Wang Shuai said: "after the Spring Festival, the price of silicon material rose significantly, the price of battery slice rose, the cost of other raw materials such as aluminum frame, welding strip and silver paste rose. Meanwhile, the price of glass was at a high level, and the cost of component manufacturers was higher than the selling price. Therefore, the operating rate dropped, and the comprehensive production of components decreased by 35% or more."A person in the industry told reporters that at present, before the construction of domestic power stations, the cost of photo-voltaic modules is generally calculated according to the price of 1.65RMB per W, but this price is lower than the cost of module enterprises, so it is normal to reduce production. While, how good is the 30% price reduction of upstream photo-voltaic glass for module enterprises? Industry insiders said that photo-voltaic glass is only a small part of the cost of photo-voltaic modules, and the benefits brought by the price reduction are limited. At present, only when the prices of silicon and aluminum are adjusted, can the supply and demand of the whole industry chain be restored to balance. Industry insiders said: "although the demand for (components) is very good now, no one dares to supply, and no one dares to sign a large number of contracts, because they are all at a loss. If the downstream stops to put in due to the high price, the power station will not be put into operation, then the demand for components will drop, and that of silicon materials will also drop, reaching a balance. " At a recent press conference, the National Energy Administration said that photo-voltaic development will enter the stage of parity from this year, get rid of the dependence on financial subsidies, and realize market-oriented and competitive development. Industry insiders pointed out that if the price of upstream raw materials remains high, it is still a little difficult for photo-voltaic power generation to get on the grid at low price. Industry insiders said: "for example, in some places,such as Guangdong, some places in Northeast China and northern Hebei, it can be (affordable). But for most places, parity is still a little difficult to come true this year. "
On May 6th-9th, 2021, the 31st China International Glass Industry Technology Exhibition (China Glass 2021) will kick off at the Shanghai New International Expo Center. Guangdong ENKONGS Machinery Co., Ltd. (booth No.: N4-133) will also dress up for the exhibition, and look forward to communicating and cooperating with you. Enkong Glass Machinery as an influential industry event in the global glass industry in 2021, the 31st China Glass Exhibition always presents the development results of the world glass industry from a professional and international perspective, and builds a professional technology and business exchange platform for the industry on a large scale of exhibition . The 7 exhibition halls of the Shanghai New International Expo Center will be used in this exhibition.N1 hall is the International Exhibition Area,gathered the German and Italian national pavilions and many main stream brands in the world glass industry.N2 hall is for original glass film manufacturer and large comprehensive glass machine equipment manufacturer.N3\N4\N5\W5 hall are all for the glass production and glass deep processing equipment manufacturers.W4 hall is SMEs display area,concentrated in the fields of daily-use glass, decorative glass, abrasives, accessories, hardware, accessories, etc.Affected by the overseas epidemic, the number of foreign manufacturers participating in the exhibition has declined, but the confidence of main stream manufacturers in the foreign glass machine industry in participating of the exhibition remains undiminished. This exhibition will hold a series of professional technical lectures and manufacturer promotion activities. The topics cover glass deep processing new technology and equipment, sintered refractory materials, special glass new materials, silicon-based new materials, also the preparation and performance research field for glass machine technology and equipment development and photochromic glass.At present, the domestic glass spot goods market is generally stable, shipments in some regions have slowed down slightly, and production and sales are also weaker than that of the previous period. Although the orders in processing factory are still relatively abundant, due to the high inventory both in traders and downstream chain, coupled with the end of Huber's insured price, the willingness to keep stocking up may weaken, and the pace of mid- and downstream replenishment has slowed, so the total inventory of glass manufacturers has declined slightly this week. With the acceleration of vaccination, the surge in global demand for vaccine glass bottles has boosted the market upon the sentiment.
