Ceramic sheet opens a new era of energy saving

Recently, the State Council issued the "Opinions on Accelerating the Development of Energy-saving and Environmental Protection Industries" and established that energy-saving and environmental protection industries will become the new pillar industries of the national economy.

The architectural ceramics industry has always been known as “three highs and one low” (high energy consumption, high pollution, high consumption of resources, and low output). China's ceramics account for 60% of the world's production, but behind this is the astonishing resource consumption of 120 million tons of mineral raw materials and 32 million tons of standard coal, which is an incalculable environmental pollution cost.

Therefore, in the context of the national strategy for energy conservation and environmental protection development, whether it is from the perspective of social responsibility or corporate development, the ceramic industry's "three high models" are not sustainable.

In fact, according to Meng Zhengqiang, general manager of the sheet division of Mona Lisa New Materials Group (hereinafter referred to as “Mona Lisa”), the traditional architectural ceramics industry can also be transformed into a low-carbon direction. “That is the thin type of products. "."

It is understood that most of the tiles in the market are currently in the "overweight" state, the conventional polished bricks 300 * 300mm thickness of 6 ~ 7mm, 600 * 600mm is about 9mm, and 800 * 800mm to reach 12mm. Many industry sources pointed out that thick bricks are actually a kind of waste. Generally speaking, the current life span of domestic buildings is generally less than 30 years. Generally, polished bricks only consume less than 1 mm of their thickness in their life spans. scrap.

Compared with traditional products of the same kind, the ceramic sheet achieves the same area of ​​64.62%, saves 20.83% of electricity, saves 63.20% of water, reduces overall energy consumption by 41.33%, reduces the emission of pollutants such as dioxide*65%, and reduces the discharge of waste 71.70 %, to become a veritable low-carbon building material.

Therefore, it can be said that the thinning of ceramic tiles has become a low-carbon direction for the continuous development of the industry. It is reported that ceramic thinning has been formally written in the “Twelve Five-year Development Plan Outline of the National Building Materials Industry”.

However, in the traditional concept of consumers, the ceramic tile must be thick and solid to be durable. “The compactness of the previous tile was so poor that it would break off at a glance,” causing the thick bricks to become more popular, and the thinning of the tiles would be crowned as “stealing "The charge.

In fact, as early as the 1980s, Japan had proposed the concept of ceramic sheeting. By 2004, Spain’s ceramic sheeting had been introduced to the market. By 2007, more than 70% of European ceramics brands had ceramic sheeting. In recent years, ceramic sheets have taken up a large proportion of the market.

The domestic Mona Lisa has also started to set up a research team since October 2005 and launched the “large-size architectural ceramic sheet” (abbreviated as “pp board”) project. At present, the physical and chemical properties of the Mona Lisa building ceramic sheet (thickness 3.5mm and 5.5mm) are not compromised at all, reaching or even surpassing the traditional ceramics; fracture modulus ≥ 24MPa, breaking strength ≥ 4200N, water absorption ≤ 0.5, various Material performance far exceeds the traditional ceramics, stone, aluminum-plastic plate and other materials.

According to statistics from related agencies, China currently has about 2 billion square meters of new buildings each year, and it has 44.1 billion square meters of existing buildings, most of which are high-energy buildings. In addition, the life expectancy of buildings in China is generally low, and the energy consumption of buildings has been greatly increased in the demolition and new construction. Therefore, the production and use of building materials, including ceramic tiles, face the urgent need for energy conservation and consumption reduction. The production, transportation and use of thin bricks are important ways to reduce the energy consumption of buildings.

Today, the strategic partnership between Mona Lisa and Vanke has been eight years old. It has provided tens of millions of square meters of architectural ceramic products for 200 real estate projects across China. The main promotion of Vanke's residential industrialization project is the strategic focus of Mona Lisa.
