I think the main reason for the price increase of white glass is the price increase of raw materials. After this year's epidemic, white glass has just been sold out in the previous inventory, and it is slow to return to work because of the epidemic. Many people who used to work chose to work after the epidemic, or didn't want to leave home during that time. And the glass industry is not as simple as some other production lines. For example, the glass production line itself can't stop all day. For example, the melting furnace of the glass factory has been running for many years before it stops for maintenance. Moreover, the maintenance cycle is also very long, so the production line must be mass-produced, and the market demand is great.

Especially now, the reason for returning to work is mostly the huge demand for real estate. Although the epidemic situation is a force majeure factor, it is still necessary to hand over the house on time after the delay. Therefore, most buildings can be started, and we will seize the time to catch up with the construction period. In this way, the supply is in short supply, and the supply of glass is in short supply, which is the reason for the price increase of glass.

Then, the country began to implement the requirements from 20 18, and it was impossible to increase the production of glass in large quantities. So it took a long time to stop production, and now it is impossible to increase the production line. So glass can't keep up with the market demand. In addition, in fact, the demand and supply of glass before was actually very stable. This year is a special situation, so this situation is caused, so it is normal for prices to rise during this period.

After a large number of reasons for returning to work, there is still a high demand for glass for several months. Originally, the price of glass will rise in recent months, but this year's special situation makes this demand in short supply more obvious, so the price increase will be even greater than in previous years.

I think this phenomenon will definitely last for some time. After the output keeps up, various industries will gradually return to normal, and perhaps prices will be reduced. Therefore, it is also a long-term risk for glass manufacturers now, and they will feel that short-term price reduction is still relatively rare, so they will definitely buy more glass raw materials than before, but the price reduction will definitely happen, only a matter of time.
