The charm of glass is that it is a kind of magical material full of tension. It is like water when it is soft, and it is like diamond when it is drilled. The strong plasticity makes it its extraordinary charm. Glass belongs to the second largest category in the building materials industry. Unlike other building materials products, the development of modern science and technology makes glass an indispensable product of the national economy. Today, glass has been widely used in home decoration, automotive machinery, health care, industrial construction, aerospace and other fields. Wenzhou fire glass manufacturer
First, the development status of the glass industry
China's glass industry has experienced more than 30 years of reform and opening up, the scale of industry has been expanding, and the quality of technology and technology has made a qualitative leap, especially since the beginning of the new century, and has achieved brilliant achievements. The production of customized flat glass in Wenzhou tempered glass increased from 200 million weight boxes at the beginning of the century to nearly 800 million weight boxes in 2014, and quadrupled. In 2015, the output of flat glass was more than 800 times that of the 920,000 weight boxes in the early days of the founding of the People's Republic of China. More than 40 times of 17.84 million weight boxes, accounting for 56% of the global total; has ranked first in the world for 26 consecutive years. Industrial development has met the needs of China's national economic construction and the continuous improvement of people's living standards. Wenzhou fire glass customization
From the perspective of downstream demand, real estate is the main application area of glass, accounting for about 75% of the total demand, mainly used in decorative products such as doors and windows, curtain walls, furniture. In addition to real estate, automobile manufacturing and export are also important areas of flat glass applications, accounting for about 10% respectively. In the first 10 months of 2017, the vehicle output was 23.494 million units, an increase of 5.3% year-on-year. The sales volume of automobiles was 22.9271 million units, a cumulative increase of 4.13%, which was lower than the growth rate of 16 years, but still maintained a steady growth. It is expected that the auto sector will be in the short term. Still providing stable demand.
It is understood that China's automotive glass, glass technology has reached the world's advanced level, Fuyao's automotive glass is the world's higher processing technology. The float process in the world's three major glass processes is the core technology of China's non-national diplomatic patents.
Second, the problems facing the glass industry
After more than 20 years of rapid development, the glass industry has achieved remarkable results. However, it is undeniable that the efficiency of resource allocation is declining, the ability to innovate is insufficient, and overcapacity is increasing. We should recognize the problems in the glass industry:
1. The surge in production capacity is caused by severe overcapacity. At present, the total amount of flat glass is excessive, mainly due to the serious excess of ordinary float glass for construction, while the high-end product guarantee capability is insufficient. Most of the products have low added value and are still at the low end and subordinate status of the value chain. There is a surplus of ordinary float glass, the ratio of high-quality float method is low, and there is a big gap in the quantity and depth of secondary processing; the level of ordinary glass technology is not high, and the company has continuously launched a new production line in order to seize market share, resulting in a vicious circle; Some high-end automotive glass, super-hard glass for high-speed trains and aircraft, borosilicate fire-resistant glass, and ultra-thin glass for the electronics industry are also required to be imported. Because of overcapacity, the glass industry also has low utilization. Wenzhou tempered glass manufacturer
2. The glass industry is not only a resource-intensive industry, but also a typical large-scale industry. In recent years, as resources, energy prices and labor costs continue to rise, it is difficult for financing to be included in overcapacity industries, which has led to a significant increase in production and operating costs. On the one hand, the market demand is insufficient, the product price continues to decline; on the other hand, the cost increase, which weakens the profitability of the enterprise and becomes a constraint factor for transformation and upgrading and structural adjustment.

3. The industrial organization structure is unreasonable. At the end of 2015, the concentration of 10 glass enterprises was only 59%. The leading companies with strong technology leadership, strong resource allocation ability and strong brand influence have led the industry to lack development capability.
4. From the technical structure, the energy consumption level is about 20% higher than the international advanced level; the low-level float glass production line uses coal tar and petroleum coke as fuel, and the air pollution emission problem is more serious.
