Glass in the future 2-3 years or will maintain a tight supply


The glass industry is limited by the supply-side reform, capacity can not expand, only the stock capacity recovery. Excluding the short concentrated cold repair during the epidemic in 2020, the average annual capacity growth rate of glass from 2019 to 2021 is only 3% based on the low capacity in 2019. The industry’s in-production capacity from 2021 to mid-July is 52.24 million tons/year, up 10.6% from the same period in 2020 and 8.8% from 2019. The gap between supply and demand has led to continued strength in glass in recent years. In addition, China’s photovoltaic installed capacity is increasing rapidly, the market is expected to accompany the advent of the photovoltaic parity era, the industry is expected to maintain a compound growth rate of more than 20% before 2025.

Depp on Securities said that under the guidance of the goal of “carbon peak, carbon neutrality”, the photovoltaic industry is expected to maintain rapid development in the future. It is expected that during the “14th Five-Year plan”, the world’s annual average new installed capacity will reach 210-260GW. At the same time, with the continuous improvement of the permeability of dual-glass components, the demand for photovoltaic glass will maintain high growth. West China Securities analysis, a neutral conservative estimate of photovoltaic glass during the 145-year average annual demand of 12.5 million tons, even considering the production of new capacity, the industry will maintain a tight supply in the next 2-3 years.

Road to the decarbonization of the glass industry: electrification

Road to the decarbonization of the glass industry: electrification


Unlike steel and cement, glass has a clear path to decarbonization: electrification.

However, renewable power has been scarcer than the industry had hoped, raising concerns about its ability to meet EU climate targets.

The recovery rate of the glass bottle industry is as high as 70%.

To meet the EU’s 2030 decarbonization target, the glass bottle industry now hopes to switch gas furnaces to electricity supply, providing 80 percent of electricity and 20 percent of gas for businesses in a “Kiln of the Future” pilot.


Although recycling consumes less energy than producing glass bottles, it is still energy-intensive.

The energy used so far has been based on fossil fuels, making recycling and glass bottle production generally less green than is often assumed.

As a result, according to a senior spokesperson for THE European glass container industry body, FEVE, the glass container industry emits about 8-9 million tons of CARBON dioxide per year, which accounts for more than 1% of the EU’s 27 industrial emissions, a significant share.

In the face of decarbonization pressure, the glass packaging bottle industry for electrification.

The aim is to build a proof-of-concept furnace in Germany, where the Ardagh Group, a multinational glassmaker, is building a new plant.

Ardagh declined to comment on the construction status.

The goal is to build an electric furnace by 2023 that will use electricity to melt glass of various sizes and colors while being twice as energy-efficient as a traditional fossil fuel furnace.


Fabrice Rivet, FEVE’s technical director, said, “We want to show that it’s possible to meet with 80 percent electricity, and that’s the goal.”

For technical reasons, first-generation electric stoves were forced to derive 20 percent of their energy from natural gas.

For the second generation, we will definitely see how to replace 20 percent of the natural gas to bring some heat to the melt.

To do this, the industry is considering options such as second-generation electric heating, hydrogen or biogas, and the development of the second-generation electric furnace will begin in 2027.”

If the initial pilot goes according to plan, the model could be rapidly replicated across the glass container industry, achieving a 50% reduction in emissions by manufacturers across all plants.

However, high research and development and power costs hold back the industry, which needs public support.

The Furnace of the Future project hopes to tap into EU innovation funds and is currently in the second phase of the selection process with a €20 billion grant.

Recently, the European industry has been increasingly vocal about its challenges in decarbonizing production and remaining competitive.

While the industry’s new electric stoves will be more energy efficient than traditional fossil fuel stoves, their decarbonization effect will also largely depend on the availability of renewable electricity.

About 20 percent of Germany’s electricity comes from coal and the industry is seeking green power purchase agreements to ensure sufficient quantities of renewable energy for the future.

However, the glass industry’s shift to renewable energy has also heightened concerns in other energy-intensive industries: rising demand and the slow growth of renewable electricity.

As the economy is electrified, demand for clean power is rising in new sectors such as transportation, construction, and industry.

According to industry experts, Germany’s electricity demand will soar from 567.6 billion kilowatt-hours in 2019 to 700 billion kilowatt-hours in 10 years.

As a result, UlrikStridbæk of Danish energy company ø Rated warns that renewable power capacity needs to be increased quickly, or the supply of renewable energy will soon become a bottleneck for other sectors, such as green hydrogen production.

“We need to double existing renewable energy capacity to meet the 55% greenhouse gas target set by the EU climate law by 2030,” warns Michaela Holl.

This will further encourage EU countries and private investors to build renewable power generation capacity as soon as possible.

Container freight rates soared by 300%

Due to the spread of the global epidemic, the entire cross-border market is ups and downs, especially the logistics efficiency is the most inefficient. Also, shipping companies have increased prices unanimously, the global supply chain is unbalanced, and the actual capacity is still very tight. These conditions add up to full container space, price increase, shortage of containers, and suspension of shipping.



Since June, the freight rates of many routes such as the US route, Africa route, Mediterranean route, and Nordic route have continued to soar. According to the latest data, the US West and US East have increased by 161.6%

Glass brick is a brick body made of glass. It is made of two types of transparent or colored glass materials: hollow glass brick and solid glass brick. Especially for small apartments, when lighting conditions are limited, you want to separate areas without affecting the sense of transparency. It can also become a wall independently.

There are two main types of glass tiles: hollow glass tiles & solid glass tiles.

Hollow glass bricks are made by first using a mold to make grooved glass like an ashtray, and then two pieces of high-temperature melted grooved glass are glued together with a hollow in the middle. Such glass bricks can be soundproof and heat-insulated. .Hollow glass brick wall is suitable for non-load-bearing interior and exterior decorative walls of buildings.

The solid glass brick is made by pouring high-temperature glass liquid into the mold and directly fixed and formed and then polished by multiple procedures in the later stage. It is relatively heavy. It has a special name, crystal brick.

Glass bricks are applied to exterior walls: it has both the physicality of the wall and the transparency of the window, and more, light transmission, sound insulation, fire prevention, etc., which can be said to serve multiple purposes. High-end office buildings, hotels, and other large places can use glass bricks. Such as the Hermes House in Ginza, Tokyo

Glass bricks are used in partitions: Use glass brick walls to decorate the partitions, which can divide the large space while maintaining the integrity of the large space. This is a smart design that can bring dramatic effects, that is, it can achieve privacy while maintaining the interior Transparent feeling. Are not kitchens, living rooms, dining rooms, bathrooms, toilets, office spaces, etc. ideal places for applying glass tiles? Especially for some dark rooms without windows, it is especially suitable.

Glass bricks are used in corridors and passages: they are used in corridors to solve the contradiction between lighting and safety. As long as one wall is replaced with glass bricks, the entire corridor will become very transparent and bright. Compared with solid walls, it has good The lighting effect can effectively improve the problem of poor indoor lighting,

In addition to the common brick types, there are also many different styles of art glass bricks. Art glass tiles can be applied to various occasions, and the colors and shapes are also more diverse. They are especially suitable for partitions and small local decorations.




convex mirrors

How well do you know convex mirrors?

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Among them, convex mirrors are the most common in life.

principle of convex mirrors

A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focal point (F) and the center of curvature (2F) are both imaginary points “inside” the mirror, that cannot be reached. As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror


The convex mirror manufacturing process is divided into glass molding and mirror plating. In the factory, workers cut the glass into a round shape, then put it in a customized mold, put it into the furnace, and adjust the temperature according to the required arch height. The glass softens at high temperatures and naturally sags to form a curved surface. Because it relies on softening to sag naturally, the error range of the arch height is relatively large. The inspection standard is mainly based on the qualified diameter. After cooling, the qualified products are selected and sent to the plating mirror. The colored convex mirror uses colored glass as the raw material, and the silver convex mirror uses low-iron glass as the raw material.

How to use tempered glass safely?

Reasons for strengthening glass breakage:

The tempered glass surface is a layer of compressive stress, and the internal tensile stress layer is corresponding to the balance state. When the surface flaw extends to the internal tensile stress layer, it will cause cracking.

This type of scar can be divided into several types:
Scratches caused by hard objects, sparks during welding, flying objects, etc.
Glass damage during handling and storage.
Damage to the glass when it is embedded.
Thermal stress and damage to system stress.
?External force impact.
It is caused by impurities that occasionally exist in the glass.
unknown reason.

Characteristics of tempered glass rupture:

As long as the tempered glass is partially damaged and ruptured, it will lose the balance of stress and cause full fragmentation. Some of the fragments are scattered by granules, and some are still attached together to form a piece of fragmented aggregate. When a rupture occurs, a person in the vicinity may be hit by rain-like particles or may be hit by a large piece of aggregate. If the fragmentation block is large enough, it may hurt the human body.

Reaming or drilling of tempered glass:

After the glass is cut or drilled, the strength of the surrounding structure will be greatly weakened. In the part subjected to external force, such processing should be avoided as much as possible; if it is not, the strengthened laminated glass should be used.

When tempered glass is used in each of the following locations, it is desirable to use reinforced laminated glass:

The top of the patio is said to be used in horizontal or near-horizontal glass, such as skylights and skylights.
The outer wall of the building is used vertically. If it falls, it will hurt the objects on the ground and the glass of the human body.
Armrests or guardrails, such as glass that may cause the body or objects to fall when broken.
