INSULATING GLASS ADVANTAGE
The trend of modern architecture is to use large-area glass or even glass walls, but the advantages of single glass in lighting, weight reduction, and magnificence cannot conceal its fatal weakness of high energy consumption in heating and cooling. Hollow glass is the way to solve this contradiction. The so-called insulating glass is two or more layers of flat glass made of aluminum frames filled with desiccant and bonded with butyl rubber and polysulfide adhesive. In addition, there is also the use of vacuum pumping or argon filling in the cavity, rather than just dry air. The advantages of insulating glass are energy conservation and environmental protection. The main energy consumption in modern buildings is air conditioning and lighting, with the former accounting for 55% and the latter accounting for 23%. Glass is a thin and easy to heat transfer material in the exterior walls of buildings. The concept of insulated glass window is that the glass of the window is made of double-layer glass, filled with inert gas in the middle to form a dry gas space, and then separated by an aluminum spacing frame filled with molecular sieves and sealed with sealant strips. The trend in modern architecture is to use large areas of glass or even glass walls, but the advantages of single glass in lighting, weight reduction, and magnificence cannot conceal its fatal weakness of high heating and cooling energy consumption. Hollow glass is the solution to this contradiction. The so-called insulating glass is a two-layer or multi-layer flat glass made of an aluminum frame filled with desiccant, and bonded with butyl rubber and polysulfide adhesive.

Three major directions for the future development of the insulating glass equipment industry
The development of the insulating glass equipment industry has been nearly thirty years. The overall development level of the insulating glass equipment industry has undoubtedly taken a significant step forward. From the introduction and imitation of insulating glass equipment, to the digestion and absorption of submissions, and to today's independent innovation, insulating glass equipment has gone through these three traditional stages. With the launch of Made in China 2025 and German Industry 4.0, the equipment manufacturing industry of insulated glass equipment must keep up with the pace of Made in China 2025, keep up with the times, focus on increasing technological investment, continuously improve technological innovation capabilities, and make great efforts in intelligent manufacturing to align with the development level of insulated glass equipment in the world. From the current perspective, the future development of insulated glass equipment should focus on grasping the following three major directions: 1. The development direction of insulating glass equipment is first and foremost towards intelligence. The traditional production method of insulating glass needs to be changed. Conventional insulating glass, whether in terms of processing function, accuracy, or processing efficiency, cannot guarantee the production requirements of today's high-tech intelligent insulating glass. Developing intelligent door and window equipment suitable for the production of modern intelligent insulating glass is a need for the develop

India's anti-dumping duties on solar glass imported from China may be extended for another two years
The Directorate General of Trade Remedy (DGTR) has proposed an extension of anti-dumping duties on tempered glass (solar glass) imported from China for another two years. DGTR found that solar glass continued to be exported to India at below normal value, leading to continued dumping. During the sunset review investigation, the dumping margin increased compared to the original investigation. According to the findings, the volume of imports from China could increase substantially, given the dumping and harmful prices of exported goods. DGTR found that Chinese solar glass producers and exporters are highly export-oriented, and they have a lot of excess capacity. After a review of dumping, injury and the likelihood of continuation or recurrence of dumping and injury, the DGTR concluded that continued anti-dumping duties are necessary. background The Ministry of Finance has imposed anti-dumping duties on Chinese solar glass for five years, effective August 18, 2017. The DGTR launched an anti-dumping investigation at the request of Indian solar glass maker Borosil Renewables. After investigation, DGTR found that there is no essential difference between solar glass exported from China and solar glass produced in India. The bureau believes that domestic solar glass is comparable to imported products in terms of physical properties, production technology, manufacturing process, and uses.

Essentials for insulating glass: energy saving, durability and seal life.
Insulating glass must meet two basic requirements: energy saving and durability and sealing life. If the energy-saving effect of an insulating glass is poor, even if the durability and sealing life are long, it is still a low-grade insulating glass. On the contrary, if the energy saving performance of insulating glass is good, but the durability and sealing life are short, it is not what people are pursuing. Obviously, the ideal insulating glass should have the best energy-saving effect and the longest sealing durability at the same time. The main factors affecting the energy-saving performance of insulating glass are: glass, spacers (frames) and gases. In terms of glass, choose white glass or low-emissivity glass, cold edge (aluminum spacer) or warm edge in spacer, air or inert gas such as argon in gas. Under other conditions unchanged, the energy-saving effect of insulating glass with white glass, air and cold edge is the worst, while the energy-saving effect of insulating glass with low-emissivity glass, argon-filled interior and warm edge is the highest . The main factors affecting the durability and sealing life of insulating glass are: insulating glass sealant, sealing structure, spacers, desiccant (molecular sieve), and the quality of manual operation. It has been proved that the sealing life of insulating glass with double seal, continuous spacer and 3A molecular sieve is the longest, while the sealing life of insulating glass with single seal, four-sided gusseted aluminum spacer and 4A molecular sieve is shorter. This is also confirmed by the 20-year tracking results of the North American Insulating Glass Association on the actual use of insulating glass. In addition, the results of the accelerated aging test of insulating glass (P1 test) show that the expected sea

[Market] The German glass industry is recovering from the crisis!
The latest manufacturing data from BV Glas shows that despite the decline in sales in the first half of 2020, economic indicators show that various industries have begun to improve. In the first half of 2020, the total sales of the German glass industry was approximately 4.70 billion euros, a decrease of 4.1% from the same period of the previous year (4.9 billion euros in the first half of 2019). Domestic and foreign sales fell 5.7% and 1.8%, respectively. The most difficult industry was flat glass manufacturing, where sales fell 15% to 454 million euros (in 2019 it was 534 million euros). Flat glass is an important supplier to the automotive industry. After being severely impacted by the stagnation of the automotive industry, the flat glass refinery has also suffered losses: the overall performance was 1.74 billion euros, a decrease of 6.7% (2019: 1.87 billion euros) . However, the current business cycle index shows that the flat glass industry has begun to rebound. Affected by the poor economic conditions of commercial glass manufacturers, insulating glass composed of container glass and economical glass (beverage glass) also declined, with sales of 1.28 billion euros, a decrease of 2.1% (2019: 1.31 billion euros) . In contrast, the output value of the container glass industry increased by 8.5%, which benefited from the shift to beverage and food consumption by households. Pharmaceutical glass manufacturers have positive business expectations, and manufacturers are preparing to produce millions of glass containers to meet the demand for a vaccine against the new crown. Glass fiber and specialty glass manufacturers also increased their sales in the first half of 2020. The glass fiber industry is

Float glass terminal demand increases, manufacturer price adjustment!
From the regional point of view, the quotation of glass production enterprises in Shahe area continued to rise slightly today, the market transaction situation was fair, and the volume of goods picked up by traders and processing enterprises was relatively high. In the near future, the quotation of manufacturers in Southwest China has also increased to follow up the price changes of manufacturers in other regions. Regional trends are as follows: East China: In the near future, the general trend of glass spot market in East China is fair, the speed of de stocking of production enterprises is not reduced, and the market sentiment is improved month on month. Generally speaking, with the weather getting better, the orders of processing enterprises in the terminal market have increased month on month. It is understood that the orders of processing enterprises in the terminal market have increased by about a week, and the average orders of large, medium and small processing enterprises are relatively average. It shows that the demand of terminal market is getting better, showing the characteristics of universality. Recently, the spot price of glass has also increased and changed to a certain extent, which is basically the same as that of the same period last year. However, from the perspective of production capacity, the recent capacity increase in East China also has a certain speed, and some capacity demand will recover in the later stage. Overall, the short-term capacity increase has little impact on the spot price. South China: Today, the overall trend of glass spot market in South China is fair, and the ex warehouse situation of production enterprises maintains the level at the early stage, and the market confidence is good. The recent rise in spot prices in various regions of the country has also played a good role in supporting the higher spot prices in South China. However, it is worth noting that since this year, the increase rate of p

The Advantages of Insulating Glass
①Greater energy saving effect High-performance insulating glass, due to a layer of special du metal film, can achieve a shielding coefficient of 0.22-0.49, which reduces the load of indoor air conditioning (air-conditioning). The heat transfer coefficient is 1.4-2.8W (m2.K), which is better than ordinary insulating glass. It also exerts great efficiency in reducing indoor heating load. Therefore, the larger the window is opened, the more obvious the energy-saving effect. ②Improve the indoor environment High-performance insulating glass can intercept considerable energy from the sun into the room, thus preventing discomfort caused by radiant heat and reducing dazzling caused by sunset sunlight. ③Rich tones and artistry High-performance insulating glass has a variety of colors, which can be selected according to needs to achieve a more ideal artistic effect. Extended information The use of hollow glass is suitable for public facilities such as office buildings, exhibition rooms, libraries, and special buildings such as computer rooms, precision instrument workshops, and chemical factories that require constant temperature and humidity. In addition, it can also be used for sun protection and anti-dazzling places. Note: Dry air is enclosed in the hollow glass. Therefore, according to changes in temperature and air pressure, the internal air pressure also changes, but only a small deformation occurs on the glass surface. In addition, slight warpage may occur during man

The traditional peak season is coming soon, what opportunities and challenges will the glass industry face?
In 2020, under the impact of the "black swan" of the coronavirus, all industries, including the glass industry, have suffered considerable impact. Due to the severe impact of the coronavirus, the average inventory level of float white glass from January to March exceeded 50 days, and the price dropped rapidly from a high of 1,800 yuan/ton to a historical low of 1,200-1300 yuan/ton. All float glass companies generally entered a state of loss. Especially in March-April, the market price of glass original films dropped by a cliff, and the central China area even dropped to the lowest price in five years of 53 yuan/heavy container. As the demand side is difficult to influence and exert force, under the coordination of the association, float glass companies jointly reduced production by 30% to stabilize market prices. When the industry was crying, a company in Shandong took the lead to increase the price based on the high ex-factory price of 64 yuan/heavy container at that time. At the beginning, the industry was not optimistic about this wave of price increases, thinking it was just hype. However, the price hike has lasted for more than a few months! Companies that focus on high-end glass have advanced from the lowest ex-factory price to about 1,800 yuan/ton; on May 14, 2020, a company rose by 120 yuan/ton in a single day, which was more than ten years The highest price increase in a single day. It can be described as "rising"! Professor Niu Xiao believes: This is not a rise! Is returning to normal and reasonable prices!

Development status of glass industry
(1) Development status of glass industry in China China's daily glass industry has experienced different stages of development: in the early days of the founding of the people's Republic of China, almost all of the domestic glass industry used manual production, with backward technology and extremely low output; in the 1970s, the domestic daily glass industry began to use kilns and automatic molding equipment to produce, with an annual output of about 1 million tons. Reform and opening up to the end of the 1990s, through the introduction and reference of foreign advanced technology and equipment, China's daily glass industry has been greatly developed, but there are also low-level repeated construction, overcapacity, poor product sales and other problems, a number of daily glass enterprises closed down or even went bankrupt due to losses. After entering the 21st century, driven by the rapid growth of domestic economy and the accelerated transfer of international industries to China, China's daily glass industry, especially the glass packaging container industry conforming to the concept of green and safety, and the glassware industry closely related to modern lifestyle, has entered a period of rapid development, which is reflected in the continuous growth of industry income and profit scale, and the product quality With the continuous improvement of quality and grade, the technology gap with international advanced enterprises has been narrowing. The national enterprises represented by Shandong Huapeng, Guangdong Huaxing and Anhui Deli have begun to rise and grow, and industrial integration is in the ascendant. China has now developed into a major producer of daily glass products in the world. According to the statistics of the National Bureau of statistics, in 2013, there were 890 domestic glassware and glass packaging container

Argon Gas Filling will be more poupar
How to improve the technical performance of insulating glass auxiliary equipment Although the application of insulating glass auxiliary equipment is very extensive, but to obtain a wider range of applications, based on the market, it is necessary to continue to innovate and transform, so it is necessary to improve the technical performance of insulating glass auxiliary equipment, then how to improve it? ? The thickness of the gas spacer layer is controlled to form a heat transfer of the turbulent airflow inside the hollow glass, and the hot and cold gases of the gas are controlled to interfere with each other or the rising and falling airflows interfere with each other, thereby controlling the convective heat transfer. Filling the inside of the insulating glass with inert gas can reduce the heat insulation and sound insulation of the insulating glass. For example, the filling of argon gas and sulfur fluoride can improve the heat insulation and sound insulation performance of the insulating glass. Through the above how to improve the technical performance of insulating glass auxiliary equipment, I hope that everyone can understand the relevant methods to improve the technical performance of insulating glass auxiliary equipment.
